SMITHSONIAN INSTITUTION UNITED STATES NATIONAL MUSEUM PROCEEDINGS UNITED STATES NATIONAL MUSEUM VOLUME 47 WASHINGTON GOVERNMENT PRINTING OFFICE 1915 ADVERTISEMENT. The scientific publications of the National Museum consist of two series — Proceedings and Bulletins. The Proceedings, the first volume of which was issued in 1878, arc intended primarily as a medium for the publication of original papers based on the collections of the National Museum, setting forth newly acquired facts in biology, anthropology, and geology derived there- from, or containing descriptions of new forms and revisions of limited groups. A volume is issued annually or oftener for distribution to libraries and scientific cstablislnnents, and, in view of the importance of the more prompt dissemination of new facts, a Hmited edition of each paper is printed in pamphlet form in advance. The dates at which these separate papers are published are recorded in the table of contents of the volume. The present volume is the forty-seventh of this series. The Bulletin, publication of which was begun in 1875, is a series of more elaborate papers, issued separately, and, like the Proceedings, based chiefly on the collections of the National Museum. A quarto form of the Bulletin, known as the "Special Bulletin," has been adopted in a few instances in w^hich a larger page was deemed indispensable. Since 1902 the volumes of the series known as ''Contributions from the National Herbarium," and containing papers relation to the botanical collections of the Museum, have been published as Bulletins.

By August Busck. Of United States Department of Agriculture. The following is the second installment ^ of descriptions of Micro- lepidoptera from Panama, based on material collected by the writer while a member of the Smithsonian Biological Survey of Panama, dming two periods, from January to June, 1911, 1912. The type material is deposited in the United States National Museum, and cotypes are, as far as Dossible, exchanged with the British Museum. The citation of the type under each genus does not signify that the fixation is original in this paper, in most cases it is not; but in some as yet debatable cases the citation is necessary in order to define the author's conception of the genus in question, and the uniform citation of the genotypes will be a convenience for future students. Family COSMOPTERYGID^. Genus ERITARBES Walsingham. Type. — Eritarhes otiosa Walsingham. ERITARBES GUTTATA, new species. Labial palpi straw-yellow, with terminal joint blackish toward the face. Face, head, and thorax straw-colored. Antennse nearly as long as the forewings, straw-yellow, faintly dotted on each joint with black. Forewings shiny light straw-yellow, overlaid on exterior half with light brown; a conspicuous deep black elongate spot on the fold equidistant from apex and base of the wing; an inconspicuous dark-brown dot at the end of the fold, a few dark-brown scales at apex. Cilia straw-colored. Hindwings dark straw-colored above; underside of both wings blackish brown. Abdomen yellow. Legs whitish ochreous. Alar expanse. — 14 mm. Habitat. — Cabima and La Chorrera, Panama, May, June, Type-specimen.— Qsit. No. 16668, U.S.N.M. Reminds one in a general way of Sitotroga cerealella Ohvier. 1 The first paper was published In the Smithsonian Miscellaneous Collection, vol. 59, No. 4, 1912. Proceedings U. S.

PERIMEDE ANNULATA, new species. Labial palpi blackish brown, terminal joint somewhat lighter. AntennsB dark brown with last dozen joints silvery white. Face, head, and thorax shining black. Forewings uniformly shining black with four small deep-black tufts of erect scales, one en the cell, one at the end of the cell, one on the middle of the fold, and one near the end of the fold, all encircled with whitish scales. Ciha gray. Hind- wings light fuscous. Abdomen dark fuscous. Legs blackish; tarsal joints very indistinctly annulated with white. Alar expanse. — 11 mm. Habitat. — Corozal and Paraiso, Isthmian Canal Zone, March, May. Type-specimen.— C^t. No. 15814, U.S.N.M. Very close to Perimede particornella Busck, but of deeper black color and distinguished by the narrow wliite circlets around the tufts of raised scales. Genus WALSHIA Clemens. Type. — Walshia amorphella Clemens. WALSHIA ALBICORNELLA, new species. Labial palpi dull ochreous, shaded with black; terminal joint nearly black with extreme apex pale. Antennse ochreous, annulated with black and with apical fourth silvery white. Face ochreous. Head and thorax oclireous, dusted with brown and black. Forewings shiny ochreous, with black and brown ill-defined markings; from base of costa to basal fourth of dorsum runs an oblique, broad, black fascia containing two large tufts of raised scales; near the end of the cell is an oblique, transverse row of raised ochreous scales mottled with black; at tornus is an ill-defined group of black and brown scales, and along the terminal edge is a row of three black dots; apical part of the wing mottled with scattered black scales; cilia Ught fuscous. Hindwings dark fuscous with lighter cilia. Abdomen blackish fuscous above, underside and anal tuft ochreous. Legs ochreous with broad black bars and black tarsal annulations. Alar expanse. — 10-11 mm. Habitat. — Paraiso and La Chorrera, Panama, February, May. Type-specimen.— Cat. No. 15813, U.S.N.M. Very close to the type of the genus and difficult to distinguish from it except by its smaller size and the white- tipped antennae. WalsMa calcarata Walsingham, which also has the white-tipped antennae, differs by the white head and the clothed posterior spurs. NO. 2043. NEW MICROLEPIDOPTERA FROM PANAMA— BV8CK. 3 Family GELECHIID^ FORTINEA, new genus. Type. — Fortinea auriciliella, new species. Labial palpi long, thin, recurved; second joint slightly thickened with appressed scales, compressed, slightly ruffled in front; terminal joint slender, acute, as long as second. Antennse finely ciliate. Forewings very elongate, broadest just within tornus; costa straight until apical fourth, thence somewhat deflected to the well defined apex; termen but little oblique; dorsum straight; 11 veins; veins 10 and 11 so closely approximate and parallel as to unite thi'oughout their length into one heavy vein, only separable into its constituents under magnification; 7 and 8 stalked; 7 to costa; 2 from near middle of cell; 3 from before the end of the cell; 4 from end of cell; 1 h furcate at base. Hindwings broader than forewings; costa straight; apex pointed; termen straight, oblique; dorsum straight; 8 veins; 6 and 7 stalked; cell produced at their stalk; 5 cubital, separate; 3 and 4 separate, but approximate. Posterior tibisB hairy above. A genus of uncertain affinity though probably related to Catalexis Walsingham and Logisis Walsingham; from both of these genera it differs in having vein 9 of the forewing free and in the unusual semi- coincidence of veins 10 and 11. FORTINEA AURICILIELLA, new species. Labial palpi hght oclireous brown. Face and head hght straw- colored. Antennse light straw-colored, faintly annulated with dark brown toward their tips. Thorax hght brown. Forewings hght ochreous brown; extreme costal edge blackish brown; below tliis runs a thin, Hght ochreous, submarginal hne from base to apex, whence it turns obhquely inward straight to the middle of the fold; this thin ochi'eous Hne is edged above with dark brown and is faintly continued along the fold to the base of the wing; it gives the wing a superficial appearance of a much narrower, elachistid wing with a long cilia represented by the tornal part; along the terminal edge is a dark brown submarginal line, beyond which the wing and the cilia are strongly metalHc golden; dorsal ciHa not metallic, dark greenish browTi. Hindwings dark brownish fuscous with golden yellow tips; apical ciHa golden yellow with a deeper yellow basal line; dorsal ciHa brown. Abdomen dark brown above; underside oclireous. Legs ochreous, shaded externally with dark brown. Alar expanse. — 24 mm. Habitat. — Porto Belle, Panama, May. Type-specimen.— Qs^t. No. 15815, U.S.N.M. 4 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.47. ATOPONEURA, new genus. Type. — Atoponeura violacea, new species. Labial palpi long, recurved; second joint thickened with appressed scales, compressed, slightly rough posteriorly; terminal joint thickened with scales except at extreme tip, compressed. Antennae three-fourths, simple. Tongue well developed, spiraled. Head and thorax smooth. Forewings elongate, narrow; costa and dorsum nearly straight and par- allel; tip of the wing rounded; apex below the median Hne; termen rounded; 11 veins; 7 and 8 coincident; 6 to costa; 5 to apex; 2 and 3 stalked. Hindwings broader than forewings; costa deflected beyond the middle; apex blunt; termen slightly sinuated; dorsum nearly straight; flexus prominent; 8 veins; 3 and 4 connate; 5 cubital; 6 and 7 closely approximate; cross vein between 7 and 8 at basal fourth. Posterior tibisB hairy above. Nearest to and correlated with Simo.neura Walsingham and like it with vein 6 in the forewing running to costa but further advanced in having 5 to apex and 3 and 4 stalked. The form of the labial palpi also distinguishes it from this genus. Only one other American genus is known with a similar venation in the forewing, i. e., Idwcrates Meyrick,^ which differs, however, in having vein 2 and 3 separate while the venation of the hindwings [6 and 7 parallel and 5 absent] proves it not at all related to the present genus. ATOPONEURA VIOLACEA, new species. Labial palpi golden metallic yeUow with base and terminal joint shaded with black exteriorly. Antennae purphsh black. Head and thorax bluish black, iridescent; face a shade hghter. Forewings black, overlaid with metallic, hght blue scales and with a strong purplish sheen, especially toward apex, which, as well as the ciha, in certain light appear like burnished copper. Hindwing dark fuscous. Abdomen bluish fuscous. Legs bluish gray on the inside, black exteriorly. Alar expanse. — 14 mm. Habitat. — Trinidad Eiver, Panama, March. Type-specimen.— CQ.t. No. 15816, U.S.N.M. The species appears plain black and inconspicuous in dull light, but in reflected light it is a very brilliant insect. BELTHECA, new genus. Type. — Beltheca picolella, new species. Labial palpi long, recurved; second joint thickened with scales, which are smoothly applied on the under side, but form a short brush on the upper side; terminal joint longer than second, slender, acute. 1 Trans.

All of the thirty-odd specimens were taken on mossy tree trunks in the deep forest and their colors blended so well with those of the bark, that even when I saw them alight and after they had been disturbed by a puff of tobacco smoke, I would again and agam lose sight of these quite large speci- mens. On one large tree trunk near Alhajuela, where the majority of the specimens were taken, many hundred were quietly sitting and could not be detected except by makmg them fly up, though I knew they were there. ANACAMPSIS BISTRIGELLA, new species. Second joint of labial palpi black exteriorly with apical edge white; inner side of second jomt and the terminal joint whitish ocherous with a black dot just before the tip.

ANACAMPSIS UNISTRIGELLA, new species. Very similar to the foregoing species though somewhat darker and more greenish in color. The costal spots are nearly contiguous ; the first one smaller than in Ustrigella; the second and third separated only by a thin, white streak; there is only one white streaklet on the costal margin beyond the fascia and the longitudinal, black streak at the angle of the fascia is surrounded by white scales contiguous with the fascia; at the end of the cell are two, elongate, black streaks and the cell and dorsal part are not mottled.

Uricli from the pods of Crotolaria. There has been for many years a specimen of this species in the United States National Museum, bred by Dr. H. G. Dyar from pods of ' 'woman's tongue," Acaciaf sp. at Nassau, Providence Island, British West Indies, in 1891, which indicates a quite extensive range of the species. While collating Mr. Meyrick's descriptions of East Indian genera with my sjmoptic tables I recognized in his Paraspistis ioloncJia^ described from four Ceylon specimens my Lipatia crotolariella, described from Trinidad, and sent Mr. Meyrick a specimen of the latter for verification. Mr. Meyrick concurred in this synonymy and was good enough to give me the further synonomy of Gelechia palpigera Walsmgham, described from East Africa. This interesting species, previously also recorded by the author from the Bahamas, was taken at Alhajuela and Corozal, Panama, April, 1911. It breeds in the pods of Crotolaria and has attained its remarkable geographic distribution with its food-plant. Genus RECURVARIA Haworth. Type. — Recurvaria nanella Hiibner.

This large, handsome species has a noteworthy resemblance to the somewhat larger Arctiid moth, Automolis (Cratoplastis) diluta Felder.^ and even more strLkingly so to the Lithosiid Diarhahdosia coroides Schaus^ and to the Stenomid moth, Stenoma lampyridella Busck,^ both of which were taken at the same place and at the same time as Costoma hasiroseUa. The same coloration in all these species, though differently placed, give the same general impression at first sight; they all probably imitate a large lampyrid beetle, CratomorpTius sp., which occurred commonly at the same time and place as the last three named Lepidoptera and which both in flight and alighting resemble them very remarkably.

This, however, is not the case in either of the two species described, the type C. lepisma Walsmgham and C. stenota Walsingham. With the evidence of additional material the specific identity of these is apparent; the species is quite variable; simoto was founded on two rubbed specimens in poor condition, and the name should be placed as a synonym of C. lepisma Walsingham. Types and cotypes of both are in the U. S. National Museum, and I now have a large series from all parts of Panama; the species has vein 4 approximate to but separate from 2 + 3. Such is also the condition in the two following species, while in the third, C. obnulila, the veins are as described by Lord Walsingham. These modifications, which in any of the higher families, Gelechiidee, Oecophoridse, or Cosmopterygidse, would be definite and sound gi'ounds for generic differentiation, I do not consider of such value in the generically far less crystalized family Stenomidse. 36 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.47.

Genus ATHLETA Walsingham. Athleta Walsingham, Biologia Centrali-Americana, vol. 4, Heterocera, 1912, p. 155. Type. — Atlileta trisecta Walsingham. In the description of the genus Athleta vein 2 of the forewmg is given as separate and distant from vein 3. Such, however, is not always the case in the type species under consideration. With several additional specimens from Porto Bello and Trinidad River, Panama, it is found that this character is not stable \\dthin the spe- cies, but that vein 2 may be separate, connate, or even short stalked with vein 3. wSimilar instabihty of these vems within the species is found in other groups of this family and makes the character of little value generically. The genus Atlileta may, how^ever, be separated from its nearest ally, Catarata Walsingham, by the anastomosis of veins 2 and Ic, which appears to be constant; from whatever start- ing point vein 2 runs nearly at right angles downward and into vein Ic, separating from it again just before tornus. The male of this species, which was not known at the time of the description, has a very noticeable short fold along vein 1& of the hindwings, which contains a large expansible tuft of yellowish hairs ATHLETA NIGRICANS, new species.

Type. — Jonaca compulsana Walker. Though Walker's generic descriptions are entirely inadequate for present day requirements and though my generic notes on the type of his genus Jonaca, made several years ago, are unfortunately not full enough for absolute determination, I feel reasonably safe in applying this name to the following species, which has the general habitus of the type of the genus. Below are given the generic characters of the present species, which I believe also apply to the type of the genus, J. compulsana Walker; a cursory examination of the type of this species in the British Museum will easily determine this.

Female.- — Not known but probably much larger. The species has the venation of the present genus, but the wing ornamentation of Cnissostages Zeller, which is not known to me except through descrip- tions and figures. Mr. Durrant states that this latter genus has vein 9 and 10 in the forewing stalked with 8 free, and if this proves a constant character it will amply separate the two genera, which, how- ever, are closely related. Cnissostages is also a fungus feeder, according Zeller, on Boletis arhorum. Family TINEID/E. HARMACLONA, ne^A^ genus. Type. — Harmaclona cossidella, new species. Labial palpi recurved; second joint long and bushy, especially laterally, reaching to middle of face; terminal joint very short and blunt, erect.

A large, typical, narrow-winged species, close to S. coloradella Dietz, but without any dorsal ochreous markings. SCARDIA MINIM ELLA, new species. So nearly identical in coloration and markings to the foregoing species as to suggest their identity, but only about half the size ot S. isiJimiella. The only difference seems to be the more clearly defined costal geminate spots, the lighter underside of the wing, and the lighter colored abdomen of S. minimella, all of which might be variation only. Such extreme variation in size, however, is not normal within this genus, and it is clearly obligatory, as well as undoubtedly correct, to consider them distinct. Alar expanse. — 14-17 mm.

Face and head light ochreous brown mixed with gray and white scaleso Thorax ochreous brown. Forewing light ochreous brown mixed with white, dark brown, and black scales; pattern very poorly defined, but a broad, oblique, dark brown streak may be made out from the middle of the fold to costa just before apex, adjoining the base of which is a large, blackish brown spot on the lower edge of the cell; a series of well defined, blackish brown costal spots and some diffused marginal brown spots on terminal edge. Ilindwings dark brownish fuscous. Abdomen dark brown with light ochreous under- side and anal tuft. Uncus and lateral claspers slender, curved down- ward and inward at tip. Legs oclireous on their inner side, dark brown exteriorly; tarsal joints blackish brown with narrow ochreous annulation. On the underside of the thorax just under the forewing is a large, dense tuft of ochreous gray hairs, which can be erected so as to obscure the sides of the head and the base of the fore wings. Alar expanse. — 10-12 mm. The females which were repeatedly taken in copulation with the males are considerably larger and with more pointed wings and rather lighter in general color. The labial palpi are hardly as long as in the males and more porrected. They have no thoracic tufts. Alar expense. — 17-21 mm. Habitat. — Alhajuela, Cabima, Trinidad River, Tabernilla, Paraiso, and Corozal, Panama, April, May and June. Type-specimen.— Qiit. No. 16771, U.S.N.M. In a series of more than sixty males, hardly two are quite alike and the different state of preservation adds much to the variation, but the general habitus, as well as the structural characters, makes it easy to place the species, which appears to be close to A. ridicula Meyrick, described from a unique male from Dutch Guiana. ACROLOPHUS BIFURCATA, new species.

Rathbun, Assistant Curator of Marine Invertebrates, United States National Museum. The new species and subspecies here described will be illustrated in the final report on the collections obtained in Philippine and adjacent waters during the years 1907-1910 by the steamer Albatross of the United States Bureau of Fisheries. The new forms are as follows: VaruTia altimana. PtycTiognathus guijulugani. Sesarma (Sesarma) palawanense. Sesarrna (Sesarma) vicentense. Sesarma (Sesarma) mindanaoense. Sesarma (Sesarma) edwardsi philippinense. Sesarma (Sesarma) sequifrons. Sesarma (Sesarma) tectum. Sesarjna (Holometopus) limhense. Sesarma (Parasesarma) dumacense. Sesarma (Parasesarma) moluccense jamelense. Sesarma (Parasesarma) pangauranense. MacropMhalmus sandakani. Dotilla sigillorum. Tympano7nerus pJdlippinensis. The genus Varuna^ is expanded to include those species of Ptychognatlius in which the front is prominent, sublaminar, its margin horizontal and distant from the anterior border of the antennular cavities; the antero-lateral teeth well-marked and acute; the upper surface of the wiist subquadrilateral and armed at the inner angle with a tooth or spine; all of which characters are common to typical Varuna. The species added to VaruTm resemble PtycTiog- nathus in having the exognath wider in the male than in the female. » Milne Edwards, Diet. Class. Hist. Nat., vol. 16, 1830, p. 511. Proceedings U. S.

Type.— Cat. No. 44558, U.S.N.M. Dimen^ons. — Male type, length 20.7 mm., width 21.8 mm. Surface uneven; H-depression deep; a groove either side of the intestinal region; a transverse groove runs inward behind the second and behind the third tooth; frontal and hepatic regions depressed; surface finely punctate and covered with still finer reticulating lines formed by flattened, confluent granules. Front broad, prominent, feebly bilobed, its lateral margms making an obtuse angle with the anterior margin. Upper border of orbit strongly S-shaped, forming at its union with the front a closed fissure ending in a triangular sinus. Antero-lateral margms moderately convergent, 3 teeth acute, with straight sides and separated by deep, narrow sinuses. Postero- lateral marguis subparallel, shghtly smuous; a granulated fine, begiiming a little ways from the margin and considerably behind the last lateral tooth, forms the upper boundary of the very short and broad obUquely-vertical section of the branchial region. Antennules obliquely folded; nasal lobe triangular. Sides of ischiognath parallel; in the male the exognath is large and much swollen; reaching nearly to the end of the merognath and one and three-fifths times as wide as the ischiognath; in the female the exognath is much flatter and narrower, being not quite so mde as the ischiognath. Chehpeds stout in male; a fringe of hair on upper and inner edges of merus; carpus with a long spine which is triangular at the base, the tip acuminate, a tubercle at base of spine, just below anterior margin of segment; palms high, postero-inferiorly much swoUen, posteriorly rugose; upper margin compressed and elevated in a flat lobe occupying the proximal two-thirds; fiiigers very broad and flat, narrowly gaping; immovable finger horizontal, with a blunt longi- tudinal ridge continued almost imperceptibly on the palm, and a NO. 2044. NEW PHILIPPINE CRABS— RATHBtJN. 71 sinus in the prehensile margin near the tip, teeth 9-11; dactyhis strongly arched, armed with about 13 irregular teeth. Chelipeds of female weak, the palm and fingers each with a well-marked ridge. Legs narrow; margins hairy; last 3 joints heavily fringed below; a sharp, subdistal spine on merus. Abdomen of male subtriangular; terminal segment one and one- half times as long as its middle width. This species is nearest to V. affinis (de Man) ^ but has a more sinuous orbital margin, a different-shaped maxiUiped (exognath wider, and ischiognath not widening distally), a longer, slenderer carpal spine, a lobe on upper margin of hand, a gape between the fingers. F. spinicarpus ^ has a more even carapace; less sinuous orbital margin; nasal lobe with sides angled, not straight; hand without a lobe above; merus-joints of legs with a small, inconspicuous spine; abdomen of male narrower. The lateral margins of the carapace are less incurved anteriorly than in V. tomentosa ^ or litterata * so that the carapace is squarer. The union of the anterior with the lateral edges of the front makes more of an angle than in either of those species, where the corners are rounded off. PTYCHOGNATHUS GUIJULUGANI, new species.

Exognath broader than iscliiognath in both sexes, more so in male than in female; ischiognath with subparallel sides; antero-external lobe of merognath very broad. In the male the inner angle of the wrist is rectangular, not toothed ; hand massive, with a squarish patch of hair at the distal end, which is continued part way on the fingers. The dactylus is a little more than twice as long as the upper margin of the palm, is finely toothed, and when closed leaves a gap between it and the horizontal fixed finger; the latter has fewer teeth, 2 or 3 of which near the middle are large. In the female the wi'ist bears an equilateral, acute tooth at its inner angle, the chela is weak, with a well-marked granulate ridge above the lower margin, and grooved fijigers; near the tips there is on the inner and outer surfaces a row of short hau's which are appressed against the horny tips. Legs rather narrow; no spine on meropodites; last 2 joints moder- ately hairy; the second and third pairs are about one and tliree- fomi-hs times, the last pair one and one-fourth times, the length of the carapace. Differs from P. harbata ^ in having the carapace a little narrower; front more advanced and less deflexed, lacking the double row of granules in that species; upper line of orbit more oblique and more sinuous; epistome about half as wide; distance between epistome and maxillipeds greater; in the male the exognath is wider, ischiog- nath narrower, and lobe of merognath larger, than in harbata; these characters are present, though less marked, in the female ; inner angle of wrist of male squarer, inner distal margin of wrist shorter, so that upper surface of wrist is more oblong than in harbata (this differ- ence less evident in female); in the presence of a row of short hairs about the ends of the fingers in the female.

NEW PHTLTPPINE CRABS— RATHBUN. 73 Carapace a little broader than long, narrowing behind, the sub- rectangular epibranchial tooth at some little distance behind the acute orbital angle, the margin behind the second tooth slightly con- cave. Surface covered with tufts of coarse hair, intervening spaces smooth except for the customary granulate lines on the postero-lateral portions. Regions deeply separated from one another. Postfrontal lobes separated by deep and wide U-shaped smuses, of which the median is much larger than the lateral; submedian lobes more than one and one-half times as wide as outer lobes. Surface of front veiy much as in S. tseniolatum White, ^ bemg concave and smooth except for a few tubercles; lower margin very smuous. Upper margui of orbit long and sinuous and directed backward to the orbital tooth. Upper margin of merus of cheHped armed with a large flat sub- distal tooth; inner margin sparingly denticulate or spinose and expanded distally in a broad tooth. Outer surface of merus and carpus covered with granulated hncs and tubercles; inner angle of carpus armed with a subrectangular tooth; outer and upper surface of propodus covered with tubercles, which for the most part are depressed and separated by reticulating grooves; fingers devoid of granules or tubercles except on the upper part of the dactylus; upper margin of palm thin, crossed by short, crowded and nearly longitudinal lines of granules, close to which runs a single Une of smaller granules extendmg from the articulation with the carpus to the tooth at the distal end of the upper margin; no pronounced transverse elevation on imier surface of pahn, but a feeble trace of a ridge; this surface is sparingly dotted with granules; fingers with a narrow gape (in the female), prehensile edges furnished with low uneven teeth; upper edge of dactylus margined, and milled incon- spicuously on the proximal haK with about 25 grooves which stop short of the basal end. Ambulatory legs broad; third pair one and two-thirds times as long as carapace; merus joints broad, that of thu'd pair a little over twice as long as broad, and armed with a strong, acute subdistal tooth ; propodi long and dactyli short, the latter seven-tenths as long as the former in the tliird pair. Terminal segment of female abdomen a little longer than wide and so deeply invaginated in the sixth segment that the latter reaches nearly as far forward as does the terminal segment. Closely allied to S. tseniolatum from which it differs in its longer and narrower carapace; narrower front; in the greater difference in the width of the outer and iimer frontal lobes; in the granulate, not pectinate, ridge near the upper margin of the palm, which is closer to that margin and not straight but follows the slight curve of the margui; and in the absence of a transverse ridge inside the palm.

Our species resembles also S. lafondii Hombron and Jacquinot/ which has a similar ornamentation on the upper margin of the palm, no ridge inside the palm, but the upper margin of the movable finger entirely smooth; in this last character, S. palawanense is intermediate between tseniolatum and lafondii. The latter has an even broader carapace than tseniolatum, and its side margins are parallel instead of convergent. SESARMA (SESARMA) VICENTENSE, new species.

This crab is densely covered with pubescence everywhere except on the cornese, the terminal half of the fingers and the horny tips of the legs; tufts of longer hairs are disposed on carapace, chelipeds, and legs, including a tuft on each tubercle. Carapace almost square, except for the two lobiform teeth which project laterally beyond the orbital tooth and make the carapace wider at those points. Regions limited by wide grooves. The prin- cipal tubercles are as follows: One large, behind each frontal lobe, the middle pan further back than the outer pair; one in the middle of the mesogastric region, and one on each side and nearly in the same line on the protogastric region; two side by side on the cardiac region; about three on each branchial region. Before the hairy coat is removed the tubercles seem to be more numerous. The surface is in the main smooth and shining, and there are no oblique ridges on the postero- lateral regions. Frontal lobes promment and deeply separated, the outer a little narrower than the inner. The front widens from above downward, is lowest at the outer ends and most prominent along the lower margin; this last is convex in front view, but sinuous from above, showing six shallow prominences; surface of front uneven. Upper margin of orbit very oblique; orbital tooth very slightly advanced, outer margin convex. Chelipeds of female equal, of moderate size.

Carapace deeply sculptured; not only are the mterregional grooves deep, but the grooves separating the postfrontal lobes are continued halfway to the mesogastric region, and the branchial region shows several areolets along its inner border. Surface punctate and shining, with numerous very short and inconspicuous hairs. The antero- lateral tooth projects forward but not outward. Where the foremost of the oblique ridges joins the side margin, the latter is a little swollen. The front is about 4 times as wide as high, surface concave, sides converging below, lower margin shghtly sinuous, and in front view, arcuate as well; a bunch of coarse granules near the middle of either half. Postfrontal lobes somewhat obHque, outer pair sUghtly nar- rower than inner pair. Arm without spine above; inner margin with a triangidar tooth denticulated on the edge. Palm rather smooth, sparingly punctate, with fine rugse near the wrist and sparse granules near the top ; upper margin a smgle slightly angled, granulated line ruiming obliquely backward and outward from the distal angle of the palm to the point where it curves down to the articulation of the wrist. Within this margin and forming part of the inner surface, although visible from above, there are 2 or 3 granulated lines, the upper of which is, in the male, parallel to the upper margin; the others are also oblique but not parallel. The upper margin of the finger bears 8 or 9 scalari- f orm tubercles in the male ; in the female the tubercles are low and only 5 or 6 proximal ones are discernible. 1 Journ. Asiatic Soc.

Legs long and narrow, the third pair more than twice as long as the carapace, and its menis two and one-third times as long as wide. The spine on the upper margin of the merus- joints is acuminate. The propodites are unusually long, the anterior margin of the third one being 4 times as long as its greatest width; the dactyls, on the other hand, are rather short, that of the third leg about two-fifths as long as the propodus. The dactyli are of uncommon form, convex on the anterior margin and also, but very slightly so, on the posterior margin, down to the long-pointed tip. This species has no resemblance to any other of the subgenus Holometopus, but its general aspect is much like that of a Samoan species of the subgenus Parasesarma, which I shall describe later.

Allied to S. plicatum} The sides of the carapace are slightly con- cave; the antero-lateral tooth is acute; its outer margin does not curve inward toward the tip as in S. plicatum, but the tooth projects strongly outward. The interregional grooves are very deep, as are also the grooves separatmg the postfrontal lobes; these grooves are continued back nearly to the angles of the mesogastric region. On each branchial region there is a smooth longitudinally obhque ridge running near the side of the cardiac and intestinal regions. The lateral margins of the deflexed front converge below, while in iMcatum they diverge; that part of the front lying before the antennules is very swollen. The propodus of the cheliped is more slender than in the female of iMcatum; on the upper surface of the palm there is a pectinated ridge beginning at the distal inner angle of that surface and running in a longitudinally obhque direction, not in a trans- versely oblique direction, as in 'plicatum, parallel to this ridge there is a fine granulated ridge near the posterior margin. The protuber- ances on the upper margin of the movable finger are low and scalari- form; there are about 7 on the proximal half, after that they become very faint; each one is divided by a transverse line into a large proximal portion and a small tubercuhform distal portion.

On outer half of merus of maxilUped there is a groove subparallel to the outer margin. Chelipeds twice as long as carapace, granulate; wrist without tooth at inner angle; hands as high as their length at the middle, a little longer than the fingers measured horizontally; lower margin of propodus strongly sinuous, the manus convex below, the finger bent downward; upper margin of dactylus finely serrulate, a low tooth on the basal half of the prehensile edge; no tooth nor sinus on the prehensile edge of the immovable finger; that edge in both fingers denticulate. Legs long and narrow, sparingly hairy; merus joints dilated, without tympana, dactyli nearly as long as propodi. First two segments of abdomen very short; third longer than first and second together, sides rounded; fourth not quite so long nor wide as third, its distal edge trilobate; fifth segment about as long as its distal width, constricted at base, sides sinuous; sixth segment broader than long, sides sinuous, forming a small tooth at proximal end. The species in general appearance resembles T. stapletoni de Man,^ which has transverse orbits, horizontal immovable fingers, almost smooth palms, and stout legs. T. pusillus (de Haan)^ has a more pentagonal carapace than the new species, the orbits and also the lateral margins being more oblique; the granules on the palm are reticulated, the immovable finger is horizontal, and both fingers have a strong ridge through the middle of the outer surface; the merus joints of the legs are provided with tympana. In T. orientalis (de Man)^ the surface of carapace and hand is smooth, the carapace widens posteriorly, the cheliped and especially the carpus is elongate. In T. ceratophora (Koelbel),* the eyes talk bears a long stjdet which projects beyond the cornea, the cheUpeds are elongate, the immovable finger has a strong tooth on its prehensile edge. » Eec.

NAMES APPLIED TO THE NORTH AMERICAN BEES OF THE GENERA LITHURGUS, ANTHIDIUM, AND ALLIES.^ By T. D. A. COCKERELL, Of the University of Colorado. The Anthidiine and Lithurgine bees, representing two groups of Megachiiidae, are interesting on account of their habits, and fre- quently well-marked or even very peculiar structural characters. The Anthidiines, nearly always spotted or banded with yellow on the abdomen, are very well represented in our fauna, and are even to be found in the IMiocene deposits of Colorado. Lithurgus, on the other hand, has only a few species in our fauna, although it is an old genus, found in the European Miocene, and widely spread over the earth, even to Australia and the islands of the Pacific. LIST OF SPECIES. Genus ANTHIDIUM Fabricius, A genus of many species, found in most parts of the world, but absent from Australia and New Zealand. The females use cottony fibers in making their nests, and are called by Fabre "Cottoniers." For a discussion of the Palearctic genera and groups included by authors in Anthidium, see Entomologist's Record, vol, 21, No. 12. Tables. (1) Cockerell, Bull. So. Cal. Acad.

New name for A. maculatum Smith, preoccupied. 1 The asterisk (*) indicates that the species is in the collection of the United States National : Some species sent to the United States National Museum by Prof. T. D. A. Cockerell labeled "cotypes," are herelisted as "paratypes," since Professor Cockerell ases the name "cotype" in the sense in which the museum uses "paratype." The museum has considerable material in the Anthidiine group and when this material is all determined the number of species in its collection will be considerably increased. Of the 107 names (fossil species omitted) in this list in the Anthidiine bees, 47 are represented by speci- mens in the collection. Of this 47, 20 are types or paratypes.— J. C. Crawford.

Dyar, Custodian of Lepidoptera, United States National Museum. These strikingly colored Noctuids have long been favorites with collectors. They are best known under the name Palindia of Guenee. The DyowAjx have been generally associated with the Palindia, and are apparently allied. Dyomyx has a very long thhd joint to the palpi and presents none of the modifications of the hmd tibise of the male, so general in Palindia. Some of the species have been fre- quently interchanged between the genera. The first species of Palindia made known were by Cramer, under the general terms Phals&na Noctua and Phalsena Geometra. Hiibner ranged them m two genera, Eulepidotis and Phrygionis. The type of the latter is generally considered to be cuUaria Hiibner ( = politata StoU, not poUtia Cramer), the first species, a Geometrid. Of the former, the type is ilyrias Cramer, the first species, fixed by Butler (1892), a Palindia. Guenee next established Palindia and Dyojnyx. Walker made no new genera in this group. Butler divided Palindia in three pai'ts, using Eulepidotis for the green ones, Palindia for the white ones, and Phrygionis for the yellow ones. Bar placed them all in Palindia, included Dyomyx as closely related, if not a sub- genus, but separated the species with curved outer line under the name Calydia. The species will be treated here as done by Guenee under two names, but it will be necessary to substitute the older Eulepidotis for Palindia. Three species have been reported in the United States, Eulepidotis dominicata Guenee from southern Texas, where it may even be estab- lished, E. micca Druce, recently reported from Texas by Barnes and McDunnough, and Dyomyx merricki Holland from Pennsylvania, where it was probably accidentally imported on tropical fruit. Nothing is known of the larvae or life history of any of the rather numerous species. One hundred and three species are here considered of Eulepidotis and twenty of Dyomyx. Proceedings U. S.

THE GENERA PALINDIA AND DYOMYI—DYAR. It) 5 EULEPIDOTIS SYLPHA Dyar. Tills will be more fully described in my fourth paper on Mexican Lepidoptera to be published in the present volume of the ProceecUngs of the United States National Museum. The two types are before me — a male from Costa Rica and female from Mexico. EULEPIDOTIS GLAUCOPASA Dyar. This also will be considered in my fourth Mexican paper. Five specimens are before me, all from Mexico. EULEPIDOTIS SCHEDOGLAUCA, new species. Grass green; fore wing with the costa very narrowly brown; lines slender, brown, straight, shghtly widened and luteous filled on costa, converging a little in the direction of tornus; costal area of liind wing shaded with orange; outer margin entire, without modification or marginal mark; a spot of raised scales before the margin, black within, silver without; tornus and fringe at submedian touched with orange; a terminal black line, touched with silver; fringe interHned with green and tipped with brown. Beneath greenish, washed over with brown; two curved brown lines on fore wing. Expanse, 27 mm. Coty pes. —Male and female. Cat. No. 15705, U. S. Nat. Mus.; St. Jean, Maroni River, French Guiana, July, 1904 (W. Schaus). Another male from Aroa, Venezuela (Schaus collection), is a little larger, otherwise identical. EULEPIDOTIS HOLOCLERA, new species. Green; forewing with pale brown edge of costa linear; Unes slender, brown, straight, without costal widening, but minute light dots at costa, converging a little in the direction of tornus; fringe green. Hindwing with large orange area at apex and costa; a small red-brown incision at submedian fold, followed by a narrow terminal line and one minute black dot. Beneath green at the bases of both wings, shaded with rusty outwardly; forewing with one faint outer Hue or clouded brown area. Expanse, 32-34 mm. Cotypes. — One male, two females. Cat. No. 15706, U. S. Nat. Mus.; St. Jean, Maroni River, French Guiana, July, 1904 (W. Schaus). Though so nearly related to E. schedoglauca, the present species has no hair tufts on the liind tibise of the male. These tufts are large and conspicuous in schedoglauca. EULEPIDOTIS STIGMASTICTA Dyar. This will be more fully mentioned in my fourth Mexican paper. Two cotyjjes, both females from Mexico, are before me. EULEPIDOTIS CROCEIPARS, new species. Fore wing green; the three lines of a duller shade, slightly con- verging in the direction of tornus; fringe tipped with brown.

Butler runs this in with juncida Guenee = aglaura Bar, wrongly, I thmk. He does not mention mdbis Guenee m this connection, as he had evidently misidentified the name (see Dyomyx fumata Felder and Rogenhofer) , apparently from followmg Walker.^ Seventeen specimens are before me from French Guiana, one from Venezuela, and one from Mexico, the latter an aberration with purple shading fillmg in the basal space up to the central line.

Walker a]:)par- ently misidentified mabis, as he describes his thecloides, which is the same thing, immediately after. Bar recognized the variability of the species, but did not recognize it as juncida Guenee, which he 1 Cat. Brit. Mus., Lep.

Packard's type was collected by the Smith- sonian Expedition to South America in 1867 "on the route from Quito across the Andes, down the Napo River, and along the river Maranon." Druce described from Ecuador. EULEPIDOTIS FORTISSIMA, new species. Shhiing white; abdomen dull ocher on posterior half; head and collar brown. Forewing with broad, dark brown band, widest on costa and running to tornus, contiguous on its lower half to the outer brown area; this is broad, bent toward base in middle, termi- nated by a double line, dull ocher filled below; a vague pale sub- marginal shade, preceded by a darker area. Hindwing yellowish, with a white ray on either side of submedian fold; a large black patch at apex; a short tail on outer margm, preceded by a black spot with white dash on one side and marginal white Ime on the other, preceded by a brownish area with scattered blkck scales, and before this a very short brown line at end of outer white ray.

Described from Brazil. I have specimens from there, the Guianas, Venezuela and Costa Rica. This species has been recorded from the United States,^ but on what material is unknown to me. I should rather expect rectimargo or electa to occur with us, as these species are in my experience much more abundant than dominicata and extend farther north. EULEPIDOTIS PERSIMILIS Guenee.

Recently Mr. Schaus and the writer, in considering the identifica- tion of Herrich-Schaffer' s name, have concluded that it is probably not a Palindia at all, or even a Noctuid, but is an earlier name for Parid- nea TiolopTisealis Ragonot, a Pyralid of the subfamily Chrysauginse.

NEW GENERA AND SPECIES OF AMERICAN BRACHYRHYNCHOUS CRABS. By Mary J. Rathbun, Assistant Curator of Marine Invertebrates, United States National Museum. The forms here described belong to the group formerly known as the Catometopa or Grapsoidea. The type-specimens of three of the species are in the Museum of Comparative Zoology and were kindly lent for description through Dr. Walter Faxon; paratypes of the same as well as t3^pes of the remaining species are in the United States National Museum. FAMILY" GONEPLACIDJD. Subfamily C^RCITsTOPLj^CIISr^E:. TRIZOCARCINUS,' new genus. Ty])e of the genus. — Trizocarcinus deritaius (Rathbun). Carapace deep, subquadrilateral, broader than long, w4th little dis- tinction of regions, convex fore and aft and from side to side. Fronto- orbital border about three-fourths of the greatest width of the carapace; antero-lateral borders arched, dentate. Front square-cut, straight, between one-third and one-fourth the width of the cara- pace, faintly notched in the mid- dle, deeply separated from the su- pra-orbital angles. Upper margin of orbit with two distinct notches. Basal segment of antenna short, the flagellum standing loosely in the orbital hiatus. The anten- nules fold transversely. Buccal cavity increasing in width dis- taUy, maxillipeds widely gaping, their merus-joint with concave an- terior margm, the antero-external lobe projecting forward not outward. Efferent branchial channels well defined. A stridulating ridge formed of parallel strife runs obliquely backward from the antero-external angle of the buccal cavity; it is played upon by a short ridge on the merus of the chehpeds.

In both sexes all seven abdominal segments are distinct and in the male the third segment covers the whole width of the sternum between the bases of the last pair of legs. This genus is closely related to Carcinoplax ^ of the Indo-Pacific region, but differs chiefly m the form and disposition of the maxil- ipeds, the separation of the front from the orbit, and the presence of striduiating apparatus.

Type of the genus. — Cyrtoplax spinidentata (Benedict). Carapace much broader than long, convex longitudinally and transversely. Regions well marked. Antero-lateral margins arcu- ate, dentate; postero-lateral margins converging. Fronto-orbital width three-lifths of width of carapace. Front advanced, lobes arcu- ate, separated only by a furrow from the orbital margin. Eyestalks tapering, corneas small. Basal joint of antemia rather Avide, inner angle just touching the front; flagellum standing in the orbital hiatus. Buccal cavity widening distaily; maxillipeds gaping, merus broader than long. Chelipeds stout, unequal, wrists subtriangular in dorsal aspect, bispinose; palms high, fingers strongly deflexed. Legs long and slender; dactylus of last pair upcurved. The first and third abdominal segments of the male do not cover the sternum; the third* fourth, and fifth segments are fused. This genus is much further removed than Eucrotopsis from the Xanthid genus Panopeus. The carapace is much broader than in Eucratopsis, the eyestalks are slenderer, the eyes smaller, and the base of the male abdomen wider, but the first segment does not cover 1 Milne Edwards, Ann.

Carapace convex antero-posteriorly and from side to side; surface covered with j^unctae and fine reticulations; coarser strise cross the anterior half transversely and nearly all the branchial region ob- liquely. Surface of fi'ont covered with short strise and minute gran- ulation; free edge arcuate and faintly bilobed, each lobe appearing in front view slightly bilobed; edge a raised finely granulated rim; post- frontal lobes low. Anteio-lateral margins convex, with one blunt tooth behind the tooth at the angle of the orbit; postero-lateral mar- gins nearly straight, convergent. Chelipeds equal, massive; upper and lower margins of arm trans- versely striated, inner expansion irregularly denticulated; outer sur- face of wrist finely striated, tooth at inner angle blunt; surface of palms nearly smooth, shining, punctate, upper surface rounded, cov- ered with finely granulated longitudinal lines which, become oblique proximally. Fingers stout, prehensile edges narrowly gaping, den- tate, a larger tooth at middle of fixed finger. Legs short and broad; third foot one and one-half times as long as carapace; merus of third pair three-fifths as broad as long; dactyli short and stumpy, armed with coarse spines. Many species of Planes have been described in the past, all of which are referable to variations of P. minutus; ^ but this form ap- pears to be distinct. It has a great resemblance to Pachygrapsus also, and forms a link between the two genera. From Planes minutus it differs in its broader carapace, somewhat depressed about the middle instead of uniformly convex; in the postero-lateral margins being nearly straight as in Pachygrapsus, not arcuate as in Planes minutus; in the more extensive striation of the dorsal surface; in the broader basal joint of the antenna; the broader merus-joint of the outer maxilliped, both its inner and outer lobes being more strongly developed; in the feebler dentation of the distal end of the inner expansion of the arm. 1 Cancer minutus Linnaeus, Syst.

AMERICAN BRACHYRHYNCH0U8 CRABS— RATHBUN. 121 Our species resembles Pachygrapsus crassipes Kandall ^ but the carapace is narrower and more convex, the post-frontal lobes lower, the lateral tooth not acute nor prominent, the postero-lateral margins less convergent, dorsal striae finer and more broken, those of the branchial region less extensive, palm without a definite marginal line above, last four segments of the abdomen of the male more regularly triangular.

Type.— Male, Cat. No. 6126, M.C.Z. Two male paratypes in U. S. National Museum, Cat. No. 22835. Dimensions. — Length of carapace of type male 16.8 mm., width of same, 18.4 mm. This species while closely related to C. angulatus Dana,- which inhabits the same region, is much smoother and less ornate so that there is no likelihood of their being confused. The carapace is not strongly areolated though the regions are well defined; the gastric region lacks the beaded transverse ridge charac- teristic of the older species. The surface is densely covered with fine depressed granules and somewhat less numerous punctse; it appears almost smooth to the naked eye, while in angulatus the surface is obviously roughened with coarser granules. As to shape, the carapace has no sharp lateral angles, the antero-lateral margins are shorter than in angulatus, and the postero-lateral margins are longer and subparallel to each other. The antero-lateral margins have four teeth, including the orbital tooth, but they are small, .especially the last two, and do not project beyond the marginal line; the intervals between the teeth diminish successively in length. There is no indica- tion of a postero-lateral tooth. The front is relatively wider than in angulatus and is feebly emar- ginate at the middle; the orbits are correspondingly smaller. The outer maxillipeds have much the same shape in the two species, but in altimanus they are shorter and wider and the gape narrower. The palms in the adult male are much higher in our species, espec- ially at the distal end, and the movable finger is strongly dcflexed; the immovable finger is nearly horizontal; there is a triangular space between the fingers for their proximal half only. 1 Journ.

As 4 specimens from different localities in Mexico agree in presenting certain characters which separate this form from the African P. spectahilis de Man, it seems best to consider it as a distinct species. The fourth tooth of the lateral margin is farther back than in spectahilis and the postero-lateral margins behind this point are less convergent and more nearly parallel. The margin of the front is more distinctly 4-lobed and the median sinus is larger and more U-shaped. The dorsal surface of the carpus is not oblong but of nearly the same length and width. The merus and carpus joints of the ambulatory legs are narrower and their sides more nearly parallel. Subfamily SKSA-RMIIN"^. SESARMA (SESARMA) VERLEYI, new species. Plate G.

There is no raised or granulated line bounding the dorsal plane on either side, but the dorsal rounds smoothly into the lateral surface. As in maracoani the anterior margin of the carapace or superior margin of the orbit is transversely sinuous, forming a triangular tooth at the antero-lateral angles, and the front between the eyes is extremely narrow and spatuliform, its median furrow linear and not reachmg the broadest part of the spatula. The lower margin of the orbit is deeply crenated or turreted throughout. The large cheliped of the male is much smoother than in the Atlan- tic form. The inner border of the arm has a large lammar expa^ision directed upward, edge arcuate, denticulate. The wrist is more elongate than in maracoani. The tubercles of the palm are few and indistmct. Fingers quite smooth except at the margins and at the base of the dactylus, where there are a few depressed tubercles. On the immovable finger there is, as in maracoani, a raised line just above the lower margin and continued backward on the palm; there is, however, no broad lobe or tooth on the proxmial half of the prehensile edge. The movable finger has a different shape from that of the allied species; while the upper margin is a regular and moderate curve, the prehensile edge is concave for its basal three-eighths, then straight to near the tip, forming a small tooth at the meeting of the two Imes; this brings the widest part of the finger just proximal to its middle. In maracoani, the widest part of the finger is near its distal > I have adopted the specific name used by Prof. Louis Agassiz on a Museum label, but hitherto unpublished.

The ambulatory legs are almost bare except the dactyli. The chief difference m the form of the male abdomen of the two species lies hi the penultimate segment: m monilifera it is less than twice as wide as it is long; in maracoani just twice as wide as long.

The hiteral angle of the carapace, marking its greatest width, is farther back. The gi*anules of the palm are of more uniform size. The palm is scarcely depressed near the immovable finger. The dac- tylus is more strongly arched. The transverse ridge across the inner surface of the palm is very prominent, is bent at an obtuse and rounded angle and is armed for nearly its whole length Avith a row of large tubercles. Near the proximal lower corner of the inner sur- face there is a longitudinally oblique stridulating ridge extending from the articulation mth the carpus to the lower marginal line of the palm almost below the angle of the transverse ridge. The strid- ulating ridge is made up of closely placed parallel lines obUque to the axis of the ridge and subparallel to the lower margin of the palm. Wlien the cheliped is flexed the ridge plays against a line of granules on the lower or anterior surface of the first ambulatory leg; this line extends nearly the whole length of the carpal segment and part way along the merus. The third to sixth abdominal segments of the male are more completely fused. EXPLANATION OF PLATES. Plate 1. Trizocarcinus dentatus, male type, X 2.. Fig. 1. Antero- ventral 'View. 2. Dorsal view. 3.

HYMENOPTERA, SUPERFAMILIES APOIDEA AND CHAL- CIDOIDEA, OF THE YALE DOMINICAN EXPEDITION OF 1913. By J. C. Crawford, Associate Curator, Division of Insects, United States National Museum. The material here listed came, unless otherwise stated, from the island of Dommica and was collected during June and July, 1913, by ^Ir. H, Wo Foote. As ahnost nothing has been recorded in the Hy- menoptera from this island, the collection is of especial interest. Superfamily APOIDEA. MELIPONA VARIEGATIPES Griboda. Eight workers of this form were taken. CENTRIS LANIPES Fabricius. One female from Guadaloupe. CENTRIS VERSICOLOR Fabricius. Six females and three males.

Habitat. — Island of Dominica, West Indies. Described from one specimen. Type.— Cat. No. 16732, U.S.N.M. ' M. cajennensis which has similarly colored legs has the mandibles yeUow at base and no dark hairs on the doi-sum of the mesonotum. The specimens recorded from the West Indies, as this species, are probably M. rufodentata Smith, which, however, may be a synonym of cajennensis. MELISSA IMPERIALIS Ashmead. Three females and eight males. One female. One male. XYLOCOPA BRASILIANORUM Linnseus. MEGACHILE FLAVITARSATA Smith. MEGACHILE MULTIDENS Fox. One female and one male. The latter smaller than the typical specimens and with the median pair of teeth on the apex of the abdomen longer and narrower. This species appears to be close to M. concinna Smith, wliich I have not seen. It differs in the female from the description of that species only in being smaller and having the ventral scopa on the penultimate segment black only at extreme sides. MEGACmLE ELONGATA Smitli. Two males which differ slightly in the last segment but otherwise agree perfectly. They are, in this one character, slightly different from another male in the collection of the United States National NO. 2048. BYMENOPTERA FROM DOMINICA— CRAWFORD. 133 Museum from Santo Domingo. As all three agree except for the slight difference of this one character, it would appear that in this species the amount of indentation of the last dorsal segment and the exact formation of the two teeth formed thereby is not constant. All three specimens are smaller than the measurements given by Smith, being only 10-12 mm. MEGACmLE BINOTATA Guerln, Two females. COELIOXYS ABDOMINALIS Guerin. Two females and one male.

TWO COTTOID FISHES FROM MONTEREY BAY, CALIFORNIA. By Charles H. Gilbert, Of Stanford University, California. The two Cottoid fishes here noted are new to Monterey Bay and one of them represents an undescribed species. The material was collected and donated by Mr. Frederick Woodworth, and was taken with a small boat dredge in shallow water near the shore. ENOPHRYS TAURINUS, new species. Plate 11, fig. 1. Type. — A specimen 64 mm. long, dredged m shallow water in Monterey Bay, near Pacific Grove, California. Cat. No. 75064, U.S.N.M. Measurements in hundredths of length without caudal fin: Length of head, 48 ; greatest depth of body, 3 1 ; least depth of caudal peduncle, 6.5; length of snout, 12.5; diameter of eye, 14; interorbital width, 7; length of maxillary, 17.5; length of preopercular spine, 21; length of occipito-nuchal ridge, 18; length of opercular ridge, 11; length of pectoral fin, 30; length of ventral fin, 19. Most closely related to E. claviger, with which it agrees in the high compressed snout and the small mouth, in the presence of a band of fine prickles above the lateral line, and in the absence of the lengthwise median plate between the nuchal ridges, which is present in E. hison. It differs from E. claviger in the shorter, more robust preopercular spine, and from both claviger and hison in the reduced number of rays in the dorsal and anal fins. Ten specimens of E. hison from Puget Sound have the fin rays as follows: Dorsal spines. Dorsal rays. Anal rays. vni IX 11 12 8 9 8 2 fi 4 3 7 Proceedings U. S. National Museum, Vol. 47— No. 2049. 135 136 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.47. In E. claviger, the fin rays are still more numerous, 5 specimens from Bering Sea examined by us having the dorsal VIII-14, and the anal with 11 or 12 rays. In both type and cotype of E. taurinus, the dorsal rays are VII-9, the anal rays 7. The orbital region is compressed and high, strongly arched above the occipital and the nasal regions. Interorbital space concave, the occipital region more deeply so. Anterior profile nearly vertical. Mouth small, the maxillary reaching vertical from front of pupil. Eye large, its diameter about twice the interorbital width, equaling the length of the snout. Nasal spines strong in the type, the nasal bones sculptured. Preorbital with two strongly protruding spinous processes in the young type, these little marked in the adult cotype. Upper preopercular spine robust, reaching well beyond the opercular margin; the usual three strong spines below it. Opercular ridge very high, rough-granular. All exposed bones of head finely granular. A single short filament at tip of maxillary, the cotype with a papilla or undeveloped filament anteriorly at its base. Teeth fine, in broad bands in the jaws, a narrow band on the vomer, the palatines naked. A short slit behind the fourth gill-arch. Isthmus very wide, equaling the distance separating the two pectoral fins. Plates of the lateral line higher than long, those anteriorly with a sharp lengthwise crest, which becomes rounded in the posterior scutes. The lateral line opens principally in a single minute pore above each plate and a similar one below it, but occasionally more than one such pore is present, especially in the anterior part of body. The space between the lateral line and the base of the dorsal is covered with fine prickles, more evident in the young than in adults. The anus is but little in advance of the first anal ray, not reached by the tips of the ventral fins. Upper parts olive or olive-brown, marbled or mottled with lighter, and with scattered small blackish brown spots. Under parts light, a white streak below middle of sides sending irregular incursions into the darker area above, this more noticeable in the adult specimen. A double dark bar below the soft dorsal, one encircling caudal pe- duncle below, a dark blotch at base of lower caudal rays. Pectoral with a dusky basal area which intensifies posteriorly to form a brown bar on middle of fin; beyond that a broad white bar, the terminal area of fin with a second narrow brown bar or with small brown spots. In the cotype, the entire lower side of head is dusky. In addition to the type, a specimen 160 mm. long, here designated a cotype, is in the collection of Stanford University, from Albatross station 2893, in the Santa Barbara Channel, southern California, depth 145 fathoms. The dorsal spines of this specimen have been injured, but can be counted without possibility of error, and the other fins are intact. NO. 2049. TWO COTTOID FISHES FROM CALIFORNIA— GILBERT. 137 ORTHONOPIAS TRIACIS Starks and Mann. Plate 11, fig. 2. Orthonopias triads Starks and Mann, Univ. of Cal. Pub. Zool., vol. 8, 1911, p. 11, fig-1- Tliis species has been known heretofore only from the type-speci- men, taken in shallow water on Cortez Banks, near San Diego. A second specimen is here recorded from Monterey Bay, where it was taken by a dredge at a depth of a few fathoms only. D. IX-16; A. 12; P. 15; V. I, 3. Lateral line with a series of 38 scales, the upper and the posterior margbis of which are wholly free and are throughout very fuiely toothed. In Astrolytes, only a part of the posterior margin is exposed and this is faintly or not at all toothed. In Axyrias, both margins are exposed and are serrulate, though less so than in Orthonojnas. Axyrias and Astrolytes are not very well separated, for while Axyrias has tjqjically a simply furcate preopercular spine, occasional exam- ples develop a thhd tooth, as is always the case in Astrolytes. If this character is disregarded, there is nothing essential to distmguish the two genera. Orthonopias is also very closely related, but may claim a certain distmction in the location of the anus, which is placed well forward near the base of the ventral fins, while in the other two genera mentioned it is almost immediately in advance of the first anal ray. The longest oblique series of scales in the dorso-lateral band contains 14 scales, while several others contain 13. A very narrow naked strip intervenes between this band and the base of the second dorsal, and even this is i^artly filled with small spinous scales lying at the base of the dorsal rays, one or two to each ray. The cirri are somewhat differently disposed than m the type. The four forming a line on top of head behind each eye are present, but the one behind eye is lacking. There is one on each nasal spine, and one or two on each of the three lower preopercular spines. The two on tip of maxillary are as described, and two are present closely apposed on posterior opercular angle. There is one on shoulder, behind the opercular angle, and several others scattered along the length of the lateral hue. This species was set aside as new prior to its pubUcation by Starks and Mann, and the figure then prepared is here reproduced. The first two dorsal spines are here represented as much shorter than those which follow. As this was apparently not true of the type, it may in this specimen be due to injury, although the fin has not that appearance. REPORT ON THE LEPIDOPTERA OF THE SMITHSONIAN BIOLOGICAL SURVEY OF THE PANAMA CANAL ZONE. By Harrison G. Dyar, Cii!(todian of Lepidoptera, United States National Museum. The present paper deals with the so-called Macrolepidoptera col- lected in Panama under the auspices of the Smithsonian Biological Survey, in the Canal Zone and from localities outside of it. Most of the specimens here treated were collected by Mr. August Busck, who went primarily to collect ' ' Micros ' ' and took the ' 'Macros ' ' only as a side issue. Consequently the larger "Macros," especially the Papilionoidea and the larger moths will be found poorly repre- sentsd in this list. The little "Macros," especially the small Noc- tuidse, LithosiidfB, and Pyralidge, will be found unusually well repre- sented, many hitherto undiscovered species being among them. There are reported on here 8,254 specimens in 1 ,713 species. Some additional material, which proved impracticable to incorporate, will raise the total number of specimens in the collection to about 9,000, but will not increase the number of species greatly.

HYLESIA INVIDIOSA, new species. Soft gray; discal mark a dark cloud; lines pale, indistinct, con- verging toward inner margin; marginal space pale on lower half. Hind wing with a single pale band, nearly straight, situated just be- yond the end of the cell. Abdomen with ocherous hair, especially dorsally. Expanse, 32-34 mm. Cotypes.—T^vo males. No. 15764, U.S.N.M.; Taboga Island, Feb- ruary, 1912 (Busck). Comes nearest to athlia Dyar, but smaller, the fore wing not rounded at apex; markings less distinct, the line on hind mng straighter and even nearer the cell. HYLESIA CRESSIDA Dyar (?). 4. Taboga Island, February and June, 1912 (Busck). The specimens are jnore rosy than alinda before me from Costa Rica and the fore wing less falcate, agreeing with cressida; but all the specimens are males, and without a female can not be placed with certainty. HYLESIA sp. A. 11. Tabogalsland, January, 1911 (Busck); Tabernilla, Canal Zone, May, 1907 (A. H. Jennings). This form lies near 'pollex Dyar, umhrata Schaus, and valvex Dyar, without agreeing entirely with either. The specimens are all in poor condition, so that a positive identification is unsafe. Mr. Busck sent up two distinct species of Hylesia larvse, but made no association of them with adults.* HYLESIA sp. B. 2. Cabima, May, 1911 (Busck). Two females, close to schausi Dyar, but less coarse in appearance, less distinctly marked; the discal spots are more distinct than the bands. There are in the collection three other females of the same character, one from Chiriqui, one from Guapiles, Costa Rica, and one from Sixola River, Costa Rica. The Costa Rican females were ten- 1 Since writing the above, I have received a bred female in good condition from Dr. S. T. Darling, together with preserved larvae, the latter conrpicuously different from either of the larva sent by Mr. Busck. Doctor Darling found the larvae on a Cashew tree (Anacardiaceae) and bred the adults. The form may be named Hylesia darling!, new species. Closest to B. pollex. Dyar from Venezuela; markings less bright and contrasted in the male; both sexes with the costa concolorous with the paler part of the wing, not with a strong dark shade as in pollex: discal spots of both wings clouded and more obscure than in pollex; abdomen of female without the paler ocherous posterior lateral tufts, the hairs concolorous with the rest of the lateral ones. Type.— Female, No. 1G038, U.S.N.M.; Ancon, Canal Zone, April, 1913 (S. T. Darling). iana.— Head rounded, about as wide as high, smooth, cherry-red, the tips of the mandibles and a spot on each side of labrum black. Body robust, cylindrical, tapering a little anteriorly; whitish, with black angular marks and spots; dorsal line forming a series of dashes mtersegmentally and little specks in the centers of the segments; two joined siibdorsal and lateral blotchcb in segmental incisures, a ring around sub- dorsal horns, spot below laterals, and lateral dot and dash on posterior third of segment; spiracles brown with irregular black dashes between; below a broad straight pale substigmatal area, then a blackish broken and vacuolated subventral band, the venter itself pale. Thoracic feet reddish; abdominal ones pale with black claspers. Horns whitish with pale branches and hairs, subdorsal, lateral, and substigmatal rows and single dorsal one on joints 12 and 13, none on anal plate, which is light reddish with black area before it on joint 13. No cervical shield. Horns all about the same length, the anterior and posterior ones but slightly longer and slenderer, none as long as the diameter of the body. NO. 2050. LEPIDOPTERA OF TEE PANAMA CANAL ZONE—DYAR. 159 tatively labeled by Mr. Schaiis as females of his ruhrifrons and dalina, respectively, but they do not possess the red feet of these forms. The present form must await the association of males for positive identification. HYLESIA sp. C. 1. La Chorrera, May, 1912 (Busck). One female similar to the above but much darker, the Hues slender and distinct; apex very dark with light lilacine spot. It does not agree with anything be/ore me, but description from the single female seems inadvisable. LONOMIA CYNIRA Cramer. 3. La Chorrera, May, 1912 (Busck); Trinidad Kiver, June, 1912 (Busck).

This falls in Agylla nivea Walker by Hampson's monograph ; ^ but Walker says of nivea, " Head black above, luteous in front " and " abdo- men testaceous above." Of the synonyms given by Hampson, mon- oleuca Walker has "palpi fawn color;" argentea Felder has the vertex of head yellow, collar shaded with purplish fuscous; virginea Schaus is a small form with pale ocher vertex and collar and abdomen gray doi-sally; plateada Dognin is Hke argentea Felder, but with ocherous abdomen instead of white; florecilla Dognin has the vertex of the head as well as the whole front and collar gray. None of the described forms, therefore, agree with the one before me. I have two males and three females of niphostibes also from the Guianas, col- lected by Mr, Schaus. APISTOSLA jmOAS Hiibner. 5.

Mr. Busck took a pair, the male marked like normal angulosa Walker, except that the lower part of the central band is yellow, the female of a form hke itJiomia Felder. The species is not itliomia, which I identify in three specimens from Costa Rica agreeing with. Felder's figure, but so much like it that five specimens in the collec- tion are so named. The present form, irenides, has a tendency to obsolescence of the basal red markings of fore wings in both sexes; of 12 before me from Panama only four have the red well developed. In two others it is reduced and in the remaining six entkely absent. Mr. Busck made the following note about the defensive secretion of this species: "On capture these butterflies, male and female, emit NO. 2050.

Near G. liquida Moschler, smaller, brown costal area confined to a small triangle not reaching below center of reniform and obliquely cut below; outer line strongly excurved, forming an obtuse angle, to which a broad streak nms from below apex, dislocated and con- tinued to center of reniform. Expanse, 23 mm. Typg.— Female, No. 15852, U.S.N.M.; Cabima, May 1011 (Busck). GONODES DENSISSIMA, new species. Dark brown; fore wing with coppery tint, especially in terminal space and inner area; Unes dark, obscure; a straight dark shade from apex to before tornus is most distinct; inner, medial and outer lines curved, slight, wavy; a waved and broken subterminal Une near the margin, dark without, coppery mthin. Hind wing solidly black-brown. Expanse, 28 mm. Type.— Female, No. 15838, U.S.N.M.; Trinidad River, IMarch, 1912 (Busck). The angulation on the outer margin is at vein 3 instead of 4 as usual in the genus; the palpi are obliquely ascending instead of sharply upturned; the eyes have long cilia from behind and below, none at all from the upper side or in front. The species does not fit well in Gonodes, or even in the subfamily Acronyctinae, but vein 5 of hind wing is weak and arises from middle of discocellulars, so that it can not be placed in the Plusiinse. MENOPSIMUS CRAMBIFORMIS, new species. Fore wing deep brown; inner line golden yellow, obscure, pro- duced outward in an angle in cell; outer Hne far outward, with a sharp outer angle in upper third preceded in the angle by a patch of lilacine scales and followed by a broad band of these below; costa at apex white-streaked; termen pale, with two or three black streaks; a black line followed by dull golden before fringe; an obHque whitish mark for reniform, joining outer line. Hind wing fuscous, Ughter at base. Expanse, 12 mm. Type.—No. 15840, U.S.N.M., selected from a series of 32; Trinidad River, May, 1911 (Busck); Paraiso, Canal Zone, May, 1911 (Busck); La Chorrera, May, 1912 (Busck). Since preparing the above, I have examined the type of Hypenodes dubia Schaus and beheve it to be the same species as Menopsimus cramhiformis. The type of dubia, a female, is in such poor condi- tion, rubbed and without palpi or legs, that I decide to let my new name stand, preferring a synonym to a possible misidentilication.

Hampson exammed one of the Mexican specimens and pronounced it to be his C. hsematopis, described from Argentina. It appears to me to differ in the presence of the heavy gray costal shade 202 PROCEEDINGS OF THE ^\ITI0NAL MUSEUM. vol.47. and in the course of the lines, to judge by Hampson's figure and de- scription. His male specimen from San Salvador is probably the present species, ISCADIA LEENA Druce. Gadirtha (?) leena Druce, Biol. Cent.-Amer., Lep. Het., vol. 2, 1898, p. 508. 4. Porto Bello, March, 1912 (Busck); Cabima, May, 1911 (Busck). The present species does not agree well with the characterization of the subfamily "retiaculum of male bar-shaped," the structure being a fold, twice as wide as long. But as Casandria stroca Schaus has an enthely smiilar structure and Iscadia aperta Walker has no retmaculum at all, the species may be included here among the other exceptions. MEDAVA DIMINUTA, new species. Fore wing whitish gray, shaded with purple at base and narrowly along costa; inner Ime slender, denticulate, broken into three black points m the cell; outer Une denticulate, followed by whitish, starting from costa above the large annular reniform, maldng a broad half circle to below reniform, then to inner margm; subtermmal line blackish, denticulate; terminal dots small, in a purplish shade.

Hampson's diagnosis of the genus Medava in his key ^ is in error in placing it in the section "Palpi with the third joint long and dilated at extremity." This joint is really short, as described on page 450. EGCHIRETES, new genus. Fore wing with veins 7-8 from end of accessory cell, 9 absent, 10 from top of accessory cell, 11 free.

The specimens are somewhat grayer, but appear to agree specifi- cally with a series from Santo Domingo, Cuba, and Jamaica, which I consider to be Walker's disseverans. Apparently there are three dis- tinct species here, latipes Guenee, ranging from Argentina to the United States, including the West Indies; disseverans Walker, from the Greater Antilles to Florida, Texas, Central America, and Panama; and marcida Guenee, from Texas, Mexico to Panama. These three species all occur hi the United States and have been regarded as varie- ties of repanda Fabricius. This, however, comes from the Lesser Antilles and can be distinguished at once from disseverans, which it otherwise resembles, by the abundant dense yellow scaHng on the imderside of the hind wings of the male. The larvae described by me as latipes ^ should be referred to disseverans. GONITIS EDETRIX Guen6e. 1. Corozal, Canal Zone, July, 1912 (C. P. Crafts). ANOMIS EXACTA Hubner, 7.

Closely allied to R. prxrupta Dognin from French Guiana, which, however, lacks the basal arc and has the liind wing less whitish at base. The Sixola River specimen is marked "-B. condita Schs. fide B. M." but I can not associate it with the male type of condita, of which we have no female. The Tuis specimen is marked "myconos Schs. 9 " but the type of myconos from Peru is a female and clearly distinct. NAVARCOSTES LIMNATIS Schaus. 1. Cabima, May, 1911 (Busck). NAPREPA CYLLOTA Druce. 1.

Close to A. costimacula Warren, the markings being essentially the same, but the fore wing of the male long and narrow, hind wing mod- erate, not broadly expanded, while the basal two-thirds of both wings below are washed with yellowish. Female j)ale brown above, but with the markings of the male on both sides. Expanse, male, 23 mm.; female, 21 mm. NO. 2050.

For the determination of A. costimacula I depend upon a specimen from Costa Rica labeled by Mr. Schaus. The female from French Guiana before me labeled by Mr. Warren agrees perfectly with the male type of A. argentilinea Schaus. The female type of argentilinea has lost the pale spot of hind wing on both surfaces. CHRYSOCESTIS FIMBRIARIA Cramer. 10.

Similar to the preceding, but the lines lost in a black irrorate shade that replaces the outer line and its duplication and runs along costa to base, formmg streaks on the veins ; browii marking on inner mar- gin to tornus distinct; terminal markings reduced to irrorations. Hind wing pale, with more fuscous margm. Expanse, 12 mm. Cotypes.— Two males. No. 16084, U.S.N.M.; La Chorrera, May, 1912 (Busck). Possibly this is the male of xscliyntela, of which the single male cited as paratype is badly rubbed. NOLA NEPHELEPASA, new species. Pale gray, the markmgs nearly obliterated; an aggregation of dark scales near middle of costa entering the cell; a few specks for outer line; subterminal line a waved cloud.

Near N. artata Schaus from Costa Rica, but the costal patch is longer and more outwardly oblique. NOLA NIMBIMARGO, new species. Similar to chauna, the marginal clouding blacker; subterminal line obscure; outer line powdery, denticulate, not smooth; costal band distinct on basal two-thirds, enlarged mto a small patch at the end. Hind wing translucent fuscous. Expanse, 12 mm. Ty^^e.— Female, No. 16093, U.S.N.M.; Cabima, May, 1911 (Busck).

In analytica, all the marks are orange-yellow on a white ground, broadened, diffused, the terminal line also orange, except the three minute dark dots below apex. Terminal line on hind wing a little darker than the other mark- ings, but not dark as in meliusalis. Expanse, 19 mm.

There appear to be six species among this material, but there are too few of a kind for satisfactory treatment. In the collection are three specimens labeled apygalis, two from ^Mexico (not alike), both females, and one from Costa Rica, a male, with prominence on basal joint of antenna, but it does not agree with either of the Mexican specimens. Two other species are before me from Costa Rica, but unnamed, -one with prominence on basal joint of male antenna, the other without this structure. I name herewith aU of the Panama forms, as I do not think that any of them are Guenee's apygalis, described from Colombia from a single female with the costal dots opened into rings. My nacohora is the only one showing this marking, and it does not appear to agree otherwise with apygalis. No. 1. HOHASlIS, new species.

Closely allied to B. rliealis Druce; smaller, wliiter, the subterminal line on both wings straighter, not forming two arcs as in that species; the inner line of fore -whig is very slender and faint whereas it is as distinct as the others in rhealis. Expanse, 13 mm. Type.— Female, No. 16137, U.S.N.M.; Cabima, May, 1911 (Biisck). I have placed rhealis and magnalis Guenee in BoccJioris instead of Nacoleia as done by Hampson, because I think the front of the head might as properly be described "flat and obUque" as "rounded," it being of an ambiguous shape, and by so domg I associate these species with the others wliich they resemble in markings.

Also 13 specimens from French and Dutch Guianas and three from Aroa, Venezuela (Schaus collection). One of the latter is labeled " Wachyzancla segrotalis Zell. $ " by Sir G. F. Hampson, but the palpi do not seem to me to agree with those of Pachyzaiida. The specimen examined by Sir George has the palpi broken, but anyway the specimen is very much too large for the female of segrotalis, of which I have many of the same size as males. The present species is near 8. silicalis Guenee, but the markings darker and more clearly written, the costa also dark. SYLEPTA LATICALIS Lederer. 1. La Chorrera, May, 1912 (Busck).

Two entirely different insects have been under this name in the collection, one from Ecuador, identified by Schaus, the other from French Guiana, identified by Hampson. The Panama specimens agree with the one from French Guiana, and I have accordingly accepted Hampson's identification of the species. PILETOSOMA TmALIS, new species. A little larger and broader-winged than novalis, the male antannse with a thickening bearing short hairs near the middle, the anal tuft very small and brush-like, inconspicuous; outer margui of fore wing quite straight, with a small notch at end of submedian fold. Color as in novalis and equally without markings, the darker patch at anal angle of hind wing somewhat larger and a little less contrasted. Expanse, 32 mm.

Wings broad, the outer margui rounded below, without notch; male antennae minutely cihate, unmodified; anal tuft large and rather long, but nothing like the enormous development of this structure in novalis. Bro\v'n-black with sUght bronzy reflection; NO. 2050.

As determined by Mr. Schaus from Costa Rican specimens (latilini- halis Giumee = co7itactalis Dognin), but not the latilimhalis of liis Guiana collections, nor the contactalis labeled by Mr. Dognin. In the present form, the spot on fore wing is very much larger (JLatilim- halis is "assez petite") and has no oblique prolongation below (as in contactalis). The band on the hind wing also is much wider. This is evidently a race, if not a good species. The name epime- tralis is accordingly proposed. 1 Two species before me from the Guianas are closely alied, and may be characterized here. LYGROPLA GLAPHYRA, new species.

The male has the costa yellow { = Sameodes jiavilaccata Hampson ^) ; in the female it is black and the markings are broader { = Pyrausta diledicolor ^ Dyar) . Under the name fiambaccata, Mr. Schaus sent three distinct species from his Costa Rican collections. The bright yellow one I take to be the real Jlavihaccata and the name falls before the earlier diledicolor. The reference to Sameodes mstead of Pyrausta seems preferable. The two other species agree with specmiens m the collection labeled Bocchoris insipidalis Lederer and B. actealis Walker, respectively. I therefore transfer these two names from Bocchoris to Sameodes, as the palpi of the species seem structurally identical with those oi fiambaccata. SAMEODES ACTEALIS Walker. 5.

A larger race of this species from Costa Rica has been identified as geUiasalis by Mr. Schaus, but the markings of hind wing and the color agree with declivalis. A form of this species occurs m the West Indies, for which I propose the name indianalis, in which the mark- ings are very famt, hardly legible on either wmg.

Guiana specimens are the same, and of three before me from Grenada, British West Indies, only one agrees with Ragonot's character, the two having veins 7 and 8 anastomosing nearly to apex. I have no specimens from Haiti, the type locality, but believe the character to be valueless, as the specimens all agree otherwise. MYELOIS DECOLOR Zeller. 2.

Crafts); Porto Bello, October, 1912 (G. F. Cleveland). Druce's characterization is insufficient to distinguish between the three species before me, consequently I adopt Schaus's identification of soraella in Costa Rican specimens, the male with a raised shining black disk in the cell of hind wing below, adjoined by a hair tuft. The specimens have very dark hind wings and do not agree well with Druce's figure (Plate 101, fig. 28), which comes nearer to cinilixa. I therefore suggest the alternative name drucella for this form. Type.— Male, No. 16373, U.S.N.M.; Porto Bello, October, 1912 (G. F. Cleveland). DRESCOMA CYRDIPSA, new species.

" DiscojMlpia Ragonot ^ was supposed to have been founded on Myelois fiavicans Zeller, but according to the above note, Ragonot's specimen was misidentified. Fiavicans falls in Piesmopoda, and Discopalina, with this tj^pe, therefore becomes a synonym of Piesmopoda, its diagnosis being in error, taken from a different, unnamed species.

THE VARIATIONS EXHIBITED BY THMINOPHIS ORDI- NOIDES (BAIRD AND GIRARD), A GARTER-SNAKE IN- HABITING THE SAUSALITO PENINSULA, CALIFORNIA. By Joseph C. Thompson, Surgeon, United States Navy. INTRODUCTION. The garter-snakes of the Pacific coast found west of the Sierra- Nevada-Cascade Range, from Vancouver in the north to the Teha- chapi Mountains in the south, have been assembled in the Memoir of Dr. A. G. Ruthven, under the one name of Thamnophis ordinoides (Baird and Girard).^ Tliis species presents a remarkably large series of variations, is equaled by no other in the genus, and is only approached by T. ele- gans and T. radix which occupy regions five to eight times greater in extent. The specimens upon which tliis study is based were captured on the Sausafito Peninsula, which forms the northern boundary of the Golden Gate, the entrance to San Francisco Bay. They were all taken within a radius of 3 kilometers. METHODS. In addition to enumerating the number of scale rows on the various parts of the body, it has been found that most instructive records may be obtained if note is taken of the exact gastrostege level at which an added row begins or a suppressed row ends. Assuming that a normal specimen is being examined, the following is about what may be expected: At the beginning of the neck there may be counted 10 rows of scales on each side of the median, a total of 21 rows; a little further back there are 9 rows and the median, a total of 19 rows; where this reduced count begins it will be seen that it is caused by the IV row (counting the row next to the gastrostege as the first row) being suppressed, and this occurs usually at the level of the sixth gastrostege. From tliis point on there are 19 rows until about the twenty-fifth gastrostege, where the count is increased to 21 rows; this is brought about by the addition of a row on each side, the added row being the V. This V row, with the accompanying total of 21 rows, continues to about the sixty-fifth gastrostege, when the V row is suppressed and the count of 19 rows is resumed. The 19 rows continue to the level of the eighty-fifth gastrostege, when the 1 Bull. 61, U. S. NationalMnseum, 1908, p. 147. Proceedings U. S. National Museum, Vol. 47-No. 2051. 351 352 PROCEEDINGS OF THE NATIONAL MUSEUM. rV row is suppressed, leaving 17 rows, which continue throughout the rest of the body. A specimen such as just described would have the scale rows recorded as — Neck, 19. Body, 19-21-19-17; the sequence of addition and suppression of the scale rows as — Neck, —IV. Body, + V, —V, —IV; and the complete data showing the gastrostege level at which the added rows begin and the suppressed rows end may be presented as follows : Neck. Body., 21-IV. 19+V. 21- -y. 19-IV. 17 cont'd. rt. It. rt. It. rt. It. rt. It. rt. It. 6 6 25 25 65 65 85 85 One of the variations in the scale formulae is where the body instead of having 19-21-19-17 rows, has only 19-17, that is, 19 rows ante- riorly and 17 posteriorly. In this type it is the fourth row in actual counting which is lost. In order that the data be correctly coordinated the scale rows must be given permanent numbers on that part of the body on which the highest count occurs in the species. In this case it is 21 rows, and the series are numbered from I to X in addition to the median. A specimen in which the highest count is 19 rows must be assumed to have the V rows suppressed constructively. It will have 9 rows on each side of the median; for these to be recorded in terms of the max- imum number for the species they must be counted as I, II, III, IV (V suppressed constructively), VI, VII, VIII, IX, and the median row. Another variation is where the count is 19-17-15. In tliis type the 19 rows become reduced to 17 by the suppression of the IV row, and occasionally the 17 rows become 15 by the loss of the fifth row in actual count, but this row when recorded in terms of the maximum rows for the species must be counted as the VI row. Behind the posterior pair of geneials there are usuaU}^ one or two pairs of small gular shields; these are followed by from one to three shields in the median hue which increase in width in pyramidal fashion. The shield that is regarded as the first gastrostege is the first one that is nearly the standard width; it is usually distinguished by being colored similarly to the rest of the ventrals and not white or cream-colored like the throat. VARIATION IN NUMBER OF DORSAL SCALE ROWS. Combining the records obtained by Doctor Ruthven^ with the data secured from the present series it appears that there are eight dis- 1 Bull. 61, U. S. Nat.

VARIATIONS OF THAMN0PHI8 ORDINOIDES—THOBIPSON. 355 This specimen varies from the normal in four additional characters, the shields involved being the postoculars, the posterior temporals, the supralabials, and the urosteges. This is the largest number of variations found in a smgle specimen. It also possesses the lowest number of scale" rows, 13, that has been recorded in this species. The reduction is brought about by the suppression of the scale row adjoining the median. Doctor Ruthven has demonstrated that the normal sequence of suppression in Thamnoiiliis, m terms of the max- imum number of rows, 23, for the genus is the V, VI, IV, and VII rows.^ These are adjoining rows, whereas the reduction in this speci- men from 15 to 13 rows was brought about not by the suppression of an adjoining row, but by that of one several series away, the one next to the median. Some 10 species of DipsadomorphinsD have been examined and where the scale formula was 21-19-17, 19-17-15, or 17-15-13 the sequence of suppression was first a lateral row, the IV, and then the row adjoining the median; or the sequence was reversed, and the row adjoining the median was the first to be suppressed followed by the row on the flank. BILATERALLY ASYMMETRICAL. No. 50260, male, ventrals 163. Anteriorly there are 19 rows. On the right side the V row is absent; on the left side it is very short, as it begins at the level of the thirty-ninth gastrostege and is sup- pressed at the forty-second. Over this segment of the body there are 20 rows, and posterior to it the count of 19 is resumed. The IV row is suppressed on the right at the eighty-sixth and on the left at the eighty-fifth gastrostege, leaving 17 rows, which are continued throughout. It will be noted that this series of three scales in the V row on the left side is an mtermediate condition between the normal 19-21-19-17 type and the reduced 19-17 type. No. 50313, male, ventrals 157. On the neck the IV row is sup- pressed on the right at the fifth and on the left side at the sixth ventral. Anteriorly there are 19 rows; on the right side the V row is absent, on the left it beguis at the thirty-fifth, and is suppressed at the forty-first ventral; over this short segment of the body there are 20 rows. Posteriorly the IV row is suppressed on the right at the eighty-third and on the left at the eighty-second ventral, leaving 17 rows which are continuous throughout. It will be noted that this specimen closely approaches the 19-17 type except for the short series of scales in the V row on the left side, which extends over the space of but 6 ventrals. OTHER VARIATIONS. Besides the variations in the scale formulae the specimens vary in eight additional dermal characters. The sliields involved are the pre- oculars, the postoculars, the anterior temporals, the posterior tempo- rals, the supralabials, the infralabials, the anal, and the urosteges. 1 Bull. 61, U. S. Nat. Mus., p. 17. 356 PROCEEDINGS^ OF THE NATIONAL MUSEUM. vol.47. VARIATION IN PREOCULARS. The normal condition is a single preocular. Where two exist it is due to the fragmentation of the lower one-third of the normal shield. In many normal specimens the lower one-third of the shield is indented at the margins and is lighter in color. Per cent. 1 normal 86 1-2 asymmetrical 10 2 bilateral 4 VARIATION IN POSTOCULARS. The normal condition is three shields. Where two exist it is due to the fusing of the normal middle and lower shields and where there are four it is due to the normal lower shield being horizontally divided. In some normal specimens the lower shield is enlarged and shows traces of a tendency to become divided.

The normal condition is to have 8 supralabials with the fourth and fifth entering the eye. Where the number is reduced to 7 it is due to the fusing of the normal second and third shields; in this tyi^e the third and fourth enter the eye. Wliere the count is in- creased to 9 it is due to the dividing of the normal eighth shield into 2 in which the posterior is the smaller. Per cent. 8 normal 94 8-7 asymmetrical 4 8-9 asymmetrical 2 VARIATION IN INFRALABIALS. The normal condition is to have 10 infralabials. Where the num- ber is increased to 1 1 it is due to the normal fourth shield being divided.

If compared with the two previous tables for the normal scale formula several points of interest may be ehcited. The V row is usually added, giving the maximum count of 21 rows, at the level of the base of the heart, and becomes suppressed beyond the posterior half of the liver where that organ begins to taper. The IV row is very con- stantly suppressed, leaving 17 rows, just posterior to the gall bladder. There is no variation from the normal position of the viscera in specimens with the abnormal or less frequently occurring scale formulae. Where the count is 19-17, the IV row is usually suppressed, exactly as in those with the normal formula, a little behind the gaU bladder. - As to the length of the spinal column, it is clear that whatever increase or decrease in the number of dorsal vertebrae that takes place in an individual specimen is brought about by the addition or sub- traction of vertebrae in that part of the column that is between the posterior end of the left kidney and the base of the tail. HABITAT. The Sausahto Peninsula is bounded on the east by San Francisco Bay and on the west by the Pacific Ocean; it is about 10 km. long and 5 km. wide. The hills, many of which reach an altitude of from 200 to 300 meters, are almost bare of trees. The valleys are deeply eroded and are clothed with fairly dense groves of laurel, scrub oaks, manzanita, and willows. In all the canyons the brooks cease to flow during the dry season, but in places water continues to trickle and there are many damp spots and a few water holes. 360 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.47. FOOD. There is a big salamander population, but the frogs and toads are very scarce. As the garter-snakes do not eat the salamanders, and as there are not enough frogs to support them, it proved instructive to look into their food supply. This was found to consist almost entirely of large slugs, of the genus Ariolimax. One specimen had eaten a small rodent, and another had devoured two young of its own species. This diet of slugs, eked out with an occasional indulgence in canni- balism, is an interesting example of the straits a species may be brought to when its normal food supply is not obtainable.

A NEW PEAHLY FRESHWATER MUSSEL OF THE GENUS HYRIA FROM BRAZIL. By L. S. Frierson, Of Frier son, Louisiana. Wliile looking over the Lea collection in the United States National Museum the shell to be described below was noted, the label attached to it being " Eyria corrugata, from the Amazon River, Brazil, from Captain Brown." It differs so much from that species indeed as to be only placed in Hyria on account of the radial beak sculpture, and epidermis. The shell resembles, perhaps, the Prisodon hrownianus Lea more than it does the ordinary Hyrias, but that shell is smooth, and the teeth differ considerably. The shell is decidedly novel, and really appears to be a connecting link between the genera Hyria and Diplodon. (It is not impossible that this species may be the " Hyria Tiumilis Troschel," unpublished so far as I am aware, a species said to be from Guiana, and referred to by Wiegmann in 1847, the name being suggestive.) HYRIA AMAZONIA, new species. Plate 12. Shell small, sohd, triangular, inflated. Length, 4; height, 2.7; diameter, 2 cm., narrow in front, and almost square with the base, which is straight almost to the posterior end, where there is a hint at a sulcus. The dorsum is nearly straight, rising into a slight wing, which in the type-specimen is just behind the middle. The posterior end descends rapidly to the rounded posterior point. The beaks are heavily radiately corrugated, breaking up in the center of the shell into pustulations, and becoming smooth next to the margin. Epi- dermis dull reddish brown, without other markings. The cavity of the shell is tray shaped, beak cavities very shallow. In the left valve there are two laterals, short, and remote from the cardinals, of which there is one low, compressed, and nearly vertical, in front, and a hint of another just beneath the beak. In the right valve there is one lateral and one low ragged split-up cardinal. The protractor-pedis scar is either absent or placed above the adductor scar, and is very small, confluent behind.

Very close to T. modesta Schaus, described from Costa Rica, but which I have also from Jalapa, Mexico^ In the female of modesta the hind wings are pale with a curved extra-discal gray band, which beneath is strongly arcuate and submacular. In cacodoxlca, the hind wings of the female are entirely fuscous shaded, the band beneath shaded, obscure and only shghtly arcuate. Mr. Schaus's Costa Rican specimen was identified by him as the female of modesta. Hampson' s description of the genus is in error in the statement "Proboscis absent." It is true that in the type-specimen of T. acutalls Schaus the tongue is absent, but it has been broken off, and is plainly visible in other specimens before me from the same locaUty. The large discal spot of the type is a variation only, the other speci- mens showing minute discal dot or replaced by a large white patch. A similar variation occurs in T. modesta.

Henderson and Paul Bartsch, OJ the United States National Museum. INTRODUCTION. During July, 1913, the writers made a short trip to Chincoteague, on the Atlantic shore of Accomac County, Virginia, for the purpose of ascertaining the local marine famia. Owing to the inaccessibility of this strip of coast, generally known as the "Eastern Shore," collectors seem to have neglected it. At all events, there appear to be but few records and no critical lists published of the shallow water shells from any locality between Cape May, New Jersey, and Beaufort, North Carolina. Ovir chief desire was to find out of just what ele- ments the moUuscan fauna consisted — to see how many, if any, species of southern range lapped over from Hatteras, and what northern species still persisted in this faunal area. We were happy in om- somewhat haphazard choice of a locality for we encountered at Chincoteague a greater variet}' of stations than likely can be found at any other one point along this section of the coast. There are, fnst, the interior sounds of very considerable extent. These are very shallow (4 to 12 feet), more or less thickly sown with oyster beds and with patches of eel grass, the bottom ranging from hard sand through varying degrees of hard clay to soft mud. Second, we found the unusual feature of a bight or protected cove formed by the southward drift at the southern end of Assateague Island, pro- tected from heavy wave action by a long, curved sand spit. This bight has a soft mud bottom, mth a temperature possibly 8° less than that of the open sea. The mud which we brought up with the dredge seemed almost icy to the touch. This condition is probably produced by cold springs seeping through the floor of the bight. This colder water of the bight yielded to our dredge Yoldia limatula, large and fine, and Nucula proxima, whereas just around the pro- tective spit of sand, on the ocean side, we found dead Terebras of two species, some young Busycon perversa and a valve of Cardium robustum, a somewhat startling association of species. Then, lastly, Proceedings U, S. National Museum, Vol. 47— No. 2055. 411 412 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.47. we had the open sea, which here presumably differs in no manner from other open-sea stations along the 200 miles or more of this coast. The bottom di'ops off very gradually to the edge of the con- tinental shelf, some 75 or 100 miles out. The open-sea stations we occupied were, as might be expected, very poor. The smooth, hard sand bottom seemed almost barren of life, and the softer patches that we explored contained only many dead shells — mostly small bivalves. We should admit, however, that our work in the open sea was scarcely a good test, although we made probably 20 hauls from the shore out some 4 or 5 miles, but the chart somidings indicated some more promising areas of pebbly bottom a few miles beyond what we considered the safety zone for a small motor boat. Tlie inner waters of the sound we found imexpectedly rich in molluscan life, the species, for the most part, not having been taken outside or in the bight. We spent but two full working days, and were fortunate in securing an excellent boat and obliging skipper. The material has been identified with great care, all the critical species having been sub- jected to the most rigorous investigation. The following is the list of our catch: LIST OF SPECIES COLLECTED. OSTREA VIRGINICA Gmelin. ANOMIA GLABRA VerrUl. PECTEN GIBBUS IRRADIANS Lamarck. MYXaUS EDDLIS Linnaeus. SCAPHARCA TRANSVERSA Say.

It seems useless to attempt any divisions into sub- species based upon color characters only. EUPLEURA CAUDATA Say. Exceptionally large. UROSALPINX CINEREUS Say. The enormous size of our specimens taken from the oyster beds at first led us to suspect a new species. Say's type, however, came from the Maryland shore and is much larger than the shells of this species from either north or south of this region. These, then, are probably typical cinereus and specimens from Long Island as well as those from Hatteras south belong to a much smaller race. Some of our shells measure 51.5 mm. long by 26.4 diameter, while the general average is not very much less. A few specimens (dead) dredged in the open sea are of the smaller race generally knoAvn to collectors (20.8 mm. long by 11.4 mm). EPITONIUM VIRGINICUM, new species. Plate 13, fig. 1. Shell very small, broadly conic, white. Nuclear whorls 4, well rounded, polished, separated by a strongly impressed suture. Post- nuclear whorls inflated, marked by very slender lamellar, retractive axial ribs, of which 36 occur upon the first, 48 upon the second, and 60 upon the last turn. The spaces between the axial ribs are a little more than twice as wide as the ribs, and are crossed by very fine spiral threads which run up on the sides of the ribs but do not cross their summit. Of these spiral threads about 20 occur between the sutures on the middle whorl. These threads are about one-half as wide as the spaces that separate them, and are a little more closely spaced at the summit than on the middle of the whorls. Suture strongly constricted. Periphery of the last whorl well rounded. Base well rounded, marked by the continuations of the axial ribs, which extend undiminished to the umbilical region, where they approach each other to such an extent that they become almost fused. Aperture very broadly and very regularly oval; outer lip thin, showing the external sculpture within; inner lip appressed to the body whorl, evenly curved; parietal wall covered with a thick yellowish callus. The type, Cat. No. 252568, U.S.N.M., was dredged at Chincoteague, Vu-ginia. It has a trifle more than three post-nuclear whorls, and measures: Length, 3 mm.; diameter, 1 J mm. This little gem appears to be a full-grown individual, judging by the slight thickening of the lip.

TURBONJLLA (PYRGISCUS) POCAHONTASAE, new species. Plate 14, fig. 4. Shell broadly conic, bluish white. Nuclear whorls 2 J, forming a depressed hehcoid spire, the axis of which is almost at right angles to the axis of the succeeding turns, in the first of which it is partly immersed. Post-nuclear whorls very slightly rounded, moderately shouldered at the summit, marked by strong, slightly pro tractive, broad, well rounded, somewhat curved axial ribs, of which 18 occur upon all the whorls. The intercostal spaces are about twice as broad as the axial ribs. They are well rounded and shallow. They are marked by 5 broad spiral grooves and a number of fine incised lines. The space between the summit and the first broad groove is about twice as wide as that between any of the grooves. This space is crossed by 6 fine incised spiral lines, which are not quite equally spaced, the second and third and the fourth and fifth being a little closer to each other than the others. The space between the first broad groove and the second is crossed by a strongly incised fine spiral line, and the space between the third and fourth is likewise crossed by a fine incised line. Suture well impressed. Periphery of the last whorl feebly angulated, marking the termination cf the axial ribs.

TURBONILLA (PYRGISCUS) TOYATANI, new species. Plate 14. fig. 5. Shell broadly conic, wax yellow. Nuclear whorls decollated. Postnuclear whorls appressed at the summit, marked by almost vertical axial ribs, which are about two-thirds as broad as the spaces that separate them. Of these ribs 22 occur upon all but the last turn, which has 24. Intercostal spaces marked by 6 equal and equally spaced, rather broad, deeply incised spiral lines, the first of which is about 1 ^ times as far anterior to the summit of the whorls as it is separated from the second, and three very fine lines. Two of these fine spiral lines occur between the summit and the first deeply incised line, while the third occurs halfway between the firat and second deep spirals. Suture well marked. Periphery of the last whorl feebly angulated, marking the termination of the axial ribs, which become evanescent here. Base moderately long, well rounded, marked by 13 incised spiral lines of somewhat varying strength and irregular distribution. The space between the first of these lines and the first line of pits on the spire is wider than any of the spaces be- tween the strongly incised lines of the spire. Aperture ovate ; posterior angle acute; outer lip thin, showing the external sculpture within; inner lip oblique, slightly curved, and somewhat reflected; parietal wall covered with a thin callus. The type, Cat. No. 252572, U.S.N.M., was dredged at Chincoteague, Virginia. It has 10 post-nuclear whorls, and measures: Length, 5.3 mm.; diameter, 1.5 mm.

Shell elongate-conic, wax yellow with a darker golden yellow band, which occupies the space bounded by the third and fourth incised spiral grooves. Nuclear whorls decollated, the 3 succeeding badly worn, the remainder well rounded, ornamented with retractive, rounded, moderately strong, axial ribs, which are about two-thirds as broad as the spaces that separate them. Of these ribs 22 occur upon the fourth and fifth, 26 upon the sixth, and 28 upon the penulti- mate whorl. In addition to the axial sculpture, the whorls are marked by 5 equal and almost equally spaced, strongly incised spiral lines, the first one of which is at a little greater distance below the summit than the space which separates the first and second NO. 2055. MARINE MOLLUSKS— HENDERSON AND BART8CII. 417 incised lines. The space between the summit and the first incised line is crossed by 3 very fine equal and equally spaced spiral striations. The incised lines pass up on the sides of the ribs but do not cross the summit. In addition to the above sculpture, the entire surface of the shell is marked with microscopic lines of growth and spiral striations. Suture strongly impressed. Peripheiy of the last whorl well rounded. Base moderately long, well rounded, marked by the continuations of the axial ribs, wliich disappear shortly after passing the peripheiy, and 15 incised spiral lines of somewhat varying width. There is a plain band between the fifth spiral line of the spire and the first incised line of the base a little broader than the band at the summit. Aperture ovate; posterior angle acute; outer lip thin, showing the external sculpture within; inner lip thin, some- what sigmoid, and slightly revolute; parietal wall covered with a thin callus. The type, Cat. No. 252573, U.S.N.M., was dredged at Chincoteague, Virginia. It has 8 post-nuclear whorls, having lost the nucleus and probably the first post-nuclear turn, and measures: Length, 4.2 mm.; diameter, 1.4 mm. Another specimen, in not quite as good condition as the type, has 9 post-nuclear whorls, and measures: Length, 6.2 mm.; diameter, 1.7 mm. TURBONILLA (PYRGISCUS), species? A specimen apparently of an undescribed species, but too poor to serve for description. TURBONILLA (PYRGISCUS), species? The above remarks apply also here. ODOSTOMIA (CHRYSALLIDA) TOYATANI, new species. Plate 13, fig. 2. Shell small, elongate-ovate, bluish white. Nuclear whorls obliquely immersed in the fii'st of the succeeding turns, above which only half of the last volution projects. Post-nuclear whorls feebly rounded, shouldered at the summit, marked by somewhat retractive axial ribs, which are about as broad as the spaces that separate them. Of these ribs, 20 occur upon the first, 22 upon the second and third, and 24 upon the last turn. In addition to the axial ribs, the whorls are crossed by 4 spiral cords which equal the axial ribs in strength and render the junction of the axial ribs and the spiral cords nodulous. The first of these cords is at the summit, and the fourth bounds the peripheral sulcus. The spaces inclosed between the axial ribs and the spiral cords are strongly impressed, rectangular pits, having the long axis parallel with the spiral sculpture. Suture channeled. Periphery of the last whorl marked by a strong sulcus.

Post-nuclear whorls moderately weU rounded, weakly shouldered at the summit, marked by decidedly retractive lines of growth and exceedingly fine spu'al striations. A slender spiral thi'ead is situated a little posterior to the suture, forming a slight angulation from which the whorls bend a little more abruptly to the inferior tuture. Suture strongly impressed, base of the last whorl moderately long, somewhat inflated, strongly rounded and openly umbilicated. Aperture oval; posterior angle obtuse; outer lip thin; inner lip decidedly oblique, curved and somewhat revolute; parietal wall glazed with a tliin callus.

Plate 14, fig. 1. Shell broadly conic, white. Nuclear whorls 4, the first half of the first turn smooth, the rest marked by 2 spiral cords and numerous very fine axial threads. Post-nuclear whorls well rounded, the first 4 marked with 2 tuberculated spiral cords, of which one is immedi- ately below the summit and the other a little posterior to the pe- riphery. Beginning with the fifth whorl a third spiral thread makes its appearance between the two, and on the last turn attains a size equal to the one posterior to the periphery. In addition to the spiral cords, weak axial riblets are present, which render the spiral cords tuberculated, 16 tubercles appearing on the first and second whorl, 18 upon the third and fourth, 20 upon the remaining. Suture some- what channeled. Periphery of the last whorl marked by a strong spiral cord, which is separated from the supraperipheral spiral cord by a sulcus as wide as that which separates the supraperipheral cord from the median. This sulcus is crossed by the continuations of the axial riblets, which stop at its posterior margin. Base moderately produced, marked by two spiral cords, one at the insertion of the columella and the other halfway between this and the peripheral cord. Aperture irregular, decidedly channeled anteriorly (outer lip fractured, thin) ; inner lip appressed to the base, and fused with the heavy callus which covers the parietal wall and renders the peritreme complete.

Nuclear whorls two and one-half, well rounded, smooth. The first 3 post-nuclear whorls rather well rounded ; the succeeding turns less so, while the later ones are almost flat. The whorls are marked with 420 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.47. poorly developed axial ribs which are almost obsolete on the early turns, where they are merely indicated. Of these ribs. 14 occur upon the third and fourth, 16 upon the fifth, 18 upon the sixth, and 20 upon the remaining turns. The intercostal spaces are fully twice as broad as the ribs, and are crossed by 4 low spiral bands between the sutures, which are a little wider than the spaces that separate them, rendering the axial ribs feebly nodulous at the junction with the ribs. On the last 2 turns the second spiral cord below the summit spHts, thus forming 5 spiral cords on these whorls. Beginning with the fifth whorl the cord anterior to the periphery makes its appear- ance in the suture as a small spiral band, becoming more and more exposed in the succeeding turns. The spaces inclosed between the the axial ribs and the spiral cords are shallow, impressed, squarish pits on the middle whorls, and elongate pits having their long diam- eter parallel with the spiral sculpture, on the early turns and the last 2 whorls. Suture moderately impressed. Periphery of the last whorl well rounded. Base moderately long, well rounded, marked by the feeble continuations of the axial ribs and 9 spiral cords, wliicli grow successively narrower from the periphery to the umbilical area. These cords are separated by grooves about half as wide as the cords. A strong varix, forming a decided callus, is j^resent diametrically op- posite the aperture on the last turn. The spiral cords, preceding and extending partly upon this callus, are tinged with dark chestnut brown. Aperture decidedly patulus, ear shaped, slightly channeled posteriorly and decidedly anteriorly; outer lip thin, decidedly ex- panded, evenly rounded, flesh colored with a checkerboard pattern of brown, when viewed by transmitted light, which is formed by squarish brown spots marking the intercostal portion of the spiral cords; inner lip reflected, somewhat sigmoid; parietal wall covered by a thick callus, rendering the peritreme complete. The type, Cat. No. 252569, U.S.N.M., and about 2,000 specimens were collected on the eel grass at Chincoteague Bay. The type has 11 whorls, and measures: Length, 8.3 mm.; diameter at the aperture, 3 mm.; and 2.2 mm. at the antepenultimate whorl. There are several species of Diastema tied up under the names of Bittium nigrum Totten, and Diastoma varium Pfeiffer. It would be out of place in the present paper to discuss this subject at length, as it is to be dealt with shortly in a forthcoming monograph upon these small shells by Dr. Paul Bartsch, in which the s^monymy as well as the systematic relationship of these shells will be completely dis- cussed. The present species is more nearly related to Diastoma varium Pfeiffer, a truly West Indian species, than it is to the mol- lusk which has been known to us under that name from the shores of the South Atlantic States.

Shell minute, dark chestnut brown, except the apex, which is yel- lowish white. Nuclear whorls 4, well rounded, smooth. Post-nuclear whorls well rounded, marked by strong axial ribs, of which 16 occur upon all the whorls but the last, which has 18. In addition to the axial ribs, the whorls are marked by 3 strong spiral cords of which the first, wliich is a little less strong than the rest, is at the summit. The junctions of the axial ribs and the spiral cords form strong tuber- cles, which are slightly elongate on the fii-st two cords below the summit, while on the last cord they are truncated posteriorly, sloping gently anteriorly. The spaces inclosed between the spiral cords and the axial libs are rectangular pits on all the whorls but the last; on which they are well rounded. Suture strongly constricted. Pe- riphery of the last whorl marked by a strong somewhat flattened keel, to which the axial ribs extend. Base moderately produced, marked by two spiral cords, one at the insertion of the columella, and another halfway between this and the peripheral cord. Aperture irregular, decidedly channeled anteriorly; posterior angle acute; outer lip thin, showing the external sculpture within. The type. Cat.

A list of Dominican Lepidoptera was published many years ago by Godman and Salvin and Herbert Druce.^ The present list adds some species, but others abeady reported are missing from this collection. All the specimens were taken by H. W. Foote, either in June and July, 1913, or without definite data. The data are therefore omitted under the specific headings. The names of the species are followed by the number of specimens taken. PAPILIONOIDEA. DANAIS PLEXIPPUS Linnaeus. 1. COLAENIS CILLENE Cramer. 5. AGRAULIS VANILLAE Linnaeus. JUNONLA GOENLA. Hubner. 4.

HOLLISTER, Assistant Curator, Division of Mammals, United States National Museum. INTRODUCTION. The nomenclatorial history of the Grasshopper Mice, or Scorpion Mice, begins with 1841, when Maximihan, Prince of Wied, in his Reise in das innere Nord-America, described Hypudaeus leucogaster from what is now the State of North Dakota. Coues, in the Mono- graphs of North American Rodentia, 1877, recognized two species, Hesperomys iOnychomys) leucogaster (Maximihan) and Hesperomys (Onychomys) torridus Coues. The only definite synopsis of the group since that date was pubhshed by Merriam in 1889,^ In this paper Onychomys was for the first time properly diagnosed and given full generic rank. Four species and one subspecies were recognized. The latest list of North American mammals,^ pubhshed in 1912, in- cludes 19 named forms, 11 of which stand as full species. Four sub- species have since been described. In the present revision of the genus two names are placed in syn- onymy, one is revived and one new subspecies is described. These changes leave the total number of recognized forms at 23, a net in- crease of 4 since 1912. While the number of races has been increased, the number of actual species has been reduced to two, the leucogaster and torridus of Coues's report of 1877. Such changes appear to be the inevitable result of study of the magnificent series of American mammals now preserved in our museums, particularly the collection of the Biological Survey. With a suite of specimens such as these collections afi'ord, direct intergradation between many supposedly distinct species is apparent, and with the increase in the number of geographical races a decrease in the number of recognizable species is to be expected. 1 North Amer.

This revision of Onychomys is the result of the study of 1,562 specimens/ almost all of which have been modern well-made skins with perfect skulls, A few alcoholic specimens and skeletons have been examined. Except in a few cases the material has been suffi- cient to work out the ranges of the subspecies in a fairly satisfactory manner, though good series of specimens, including a sufficient num- ber of adults, fi'om certam regions, will modify somewhat the bound- ary lines between forms as at present mapped. All of the 23 existing type-specimens have been examined. FORMS, CHARACTERS, AND PELAGES.
