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, are 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 establishments, and, in view of the importance of the more prompt dissemination of new facts, a limited 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 which 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.

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, during 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 possible, 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.— Eritarbes otiosa Walsingham. ERITARBES GUTTATA, new species. Labial palpi straw-yellow, with terminal joint blackish toward the face. Face, head, and thorax straw-colored. Antenne 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-specumen.—Cat. No. 16668, U.S.N.M. Reminds one in a general way of Sttotroga cerealella Olivier. 1 The first paper was published in the Smithsonian Miscellaneous Collection, vol. 59, No. 4, 1912. re PROCEEDINGS U. S. NATIONAL Museum, VOL. 47—No. 2043. 84843°—Proe.N.M.vol.47—14——1 J 2 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. Genus PERIMEDE Chambers. Type.—Pervmede errantella, Chambers. PERIMEDE ANNULATA, new species. Labial palpi blackish brown, terminal joint somewhat lighter. Antenne dark brown with last dozen joints silvery white. Face, head, and thorax shining black. Forewings uniformly shining black with four small deep-btack tufts of erect scales, one on 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. Cila 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-specumen.—Cat. No. 15814, U.S.N.M. Very close to Perimede particornella Busck, but of deeper black color and distinguished by the narrow white 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. Antenne ochreous, annulated with black and with apical fourth silvery white. Face ochreous. Head and thorax ochreous, 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 light 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-specuemen.—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 antenne. Walshia calcarata Walsingham, which also has the white-tipped antenne, differs by the white head and the clothed posterior spurs. NO. 20438. NHW MICROLEPIDOPTERA FROM PANAMA—BUSCK. 3 Family GELECHIDA FORTINEA, new genus. Type.— Fortinea aurieiliella, 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. Antenne 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 throughout 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 6 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 tibize hairy above. A genus of uncertain affinity though probably related to Catalezis 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 light ochreous brown. Face and head light straw- colored. Antenne: light straw-colored, faintly annulated with dark brown toward their tips. Thorax light brown. Forewings light ochreous brown; extreme costal edge blackish brown; below this runs a thin, light ochreous, submarginal line from base to apex, whence it turns obliquely inward straight to the middle of the fold; this thin ochreous line 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 metallic golden; dorsal cilia not metallic, dark greenish brown. Hindwings dark brownish fuscous with golden yellow tips; apical cilia golden yellow with a deeper yellow basal line; dorsal cilia brown. Abdomen dark brown above; underside ochreous. Legs ochreous, shaded externally with dark brown. Alar expanse.—24 mm. Habitat—Porto Bello, Panama, May. Type-specumen.—Cat. 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. Antenne 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 line; 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; crossvein between 7 and 8 at basal fourth. Posterior tibie hairy above. Nearest to and correlated with Simoneura 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., Idiocrates 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 yellow with base and terminal joint shaded with black exteriorly. Antenne purplish black. Head and thorax bluish black, iridescent; face a shade lighter. Forewings black, overlaid with metallic, light blue scales and with a strong purplish sheen, especially toward apex, which, as well as the cilia, 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 River, Panama, March. Type-s pecomen.—Cat. 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 prcolella, 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. Ent. Soc. Lond., 1900, p. 19. No. 2048. NHW MICROLEPIDOPTERA FROM PANAMA—BUSCE. 5 Fore wings elongate, ovate, apex round pointed, termen oblique; 11 veins: 7 and 8 coincident to costa; 6 to apex; 2, 3, 4, and 5 equi- distant; (7 and 8), 9,10, and 11 equidistant; 11 from beyond middle of the cell; 1b furcate at base. Hind wings somewhat narrower than the forewings with costa gently arched, apex produced, termen strongly sinuate, dorsum straight; 7 veins: 6 obsolete; 7 to apex; 2, 3, 4, and 5 well separated, equidistant. Posterior tibie rough haired above. A development from Aristotelia, correlated with Chrysopora Clemens, from which it differs by the coincident veins 7 and 8 of the forewings. BELTHECA PICOLELLA, new species. Second joint of labial palpi whitish gray with blackish tuft; third joint black with a broad, longitudinal, silvery line and with silvery apex. Eyes in the living specimen red. Lower face silvery white; upper face and head dark iridescent brown. Thorax blackish brown. Forewing blackish brown with a thin outwardly oblique white streak- let just beyond middle of costa and with two triangular white dashes just before apex; a few scattered white scales at the end of the cell and on the fold. Cilia black; just below apex it is short so as to give the wing a slightly emarginate appearance. Hind wings blackish fus- cous with a bluish cast; cilia black. Abdomen iridescent blackish fuscous with silvery white underside. Legs blackish brown with white tarsal annulations. ; Alar expanse.—9-10 mm. Habitat —Cabima, Panama, May. Type-specimen.—Cat. No. 16669, U.S.N.M. A striking little species reminding one of the genus Apopira Wal- singham. BESCIVA, new genus. Type.—Besciva longitudinella, new species. Labial palpi long, recurved, sickle-formed; second joint somewhat thickened with scales, smooth; terminal joint longer than second, pointed. Antenne shorter than the fore wings. Fore wings narrow, elongate ovate with apex pointed; 11 veins: 7 and 8 coincident to costa; 6 separate to termen; 2, 3, 4, and 5 separate, nearly equidistant ; 11 from beyond middle of cell, subobsolete toward the edge of the wing. Hind wings somewhat narrower than the fore wings with costa and dorsum nearly straight and parallel; apex produced, termen sinuated below apex; 8 veins: 6 and 7 longstalked; 6 to apex; 3 and 4 shortstalked; 5 cubital. Posterior tibise hairy above. Allied to Untomia Busck, from which it differs in the separate veins 3 and 4 of the fore wing, the stalked veins 3 and 4 of the hind wing, and in having vein 6 of the hind wing to apex. 6 PROCEEDINGS OF THE NATIONAL MUSEUM. vou, 47, BESCIVA LONGITUDINELLA, new species. Second joint of labial palpi white, barred exteriorly with light brown; terminal joint white with two indistinct brown annulations. Antenne light brown with white annulations. Face, head, and thorax white laterally with a light brown central streak. Fore wings with the white ground color strongly overlaid by light ochreous brown and black scales; a nearly continuous, longitudinal, undulating line runs through the middle of the wing from base to apex, bordered above with pure white; another black longitudinal line covers basal four- fifths of the fold; the rest of the wing area is ochreous brown, with the costal edge slightly dusted with black. Hind wings blackish fuscous with ochreous cilia. Abdomen blackish above, light ochreous on the under side. Legs whitish ochreous, dusted exteriorly with brown. Alar expanse.—9 mm. Habitat.—La Chorrera and Trinidad River, Panama, March, April. Type-specimen.—Cat. No. 16670, U.S.N.M. GALTICA, new genus. Type.—Galtica venosa, new species. Labial palpi long, sickle-formed, reaching far beyond vertex; sec- ond joint slightly thickened with appressed scales; terminal joint nearly as long as second, slender, acute. Fore wings elongate ovate; apex bluntly pointed; termen rounded; 11 veins; 7 and 8 coincident; 4 and 5 shortstalked from the end of the cell; 2 and 3 widely separate from before the end of the cell; transverse vein nearly obsolete; 16 furcate at base. Hind wings wider than the forewings; costa nearly straight, slightly deflected beyond the middle; apex bluntly pointed; termen and dorsum rounded; 8 veins; 6 and 7 separate, though approximate; 3 and 4 connate; 5 cubital. Posterior tibie with heavy spreading tufts of long bristly hairs above. This genus comes nearest to Diadytica Walsingham, from which it differs in having veins 4 and 5 of the fore wing shortstalked and in having 3 and 4 of the hind wings connate, not shortstalked; more strikingly distinguished in the very remarkable hair development of the posterior tibie; those of Diadytica being nearly smooth. GALTICA VENOSA, new species. Labial palpi straw-yellow, with a thin, longitudinal, anterior, deep black line from base to apex, somewhat broader on the terminal joint. Face, head, and thorax purplish black, mottled with a few yellow scales. Forewings deep dull black with a broad, ill-defined, yellow band across the wing near base and with all the veins on the outer half of the wing indicated by narrow, yellow lines; an irregular aggregation of yellow scales at tornus; cilia blackish with a yellow base line. Hindwings dark fuscous. Abdomen blackish fuscous. no. 2048. NEW MICROLEPIDOPTERA FROM PANAMA—BUSCK. a Legs blackish with yellow tarsi; posterior tibie with very striking spreading tufts of yellow and black hairs, displayed conspicuously when the insect is at rest; posterior first tarsal joints thickened with smooth, dark metallic blue scales. Alar expanse.—18 mm. Habitat.—Porto Bello, Panama, April. Type-specimen.—Cat. No. 15817, U.S.N.M. Genus ANACAMPSIS Curtis. Type.—Anacampsis populella Clerck. ANACAMPSIS PECULELLA, new species. Labial palpi silvery gray, shaded with darker gray, especially an- teriorly on the terminal joint. Antenne dark brown with narrow silvery annulations. Tongue silvery white. Mead and thorax dark brownish fuscous; face somewhat lighter. Ground color of the fore- wings is white but so strongly and evenly overlaid with dark brown scales as to be obscured, except under magnification; near the base is a broad, outwardly oblique, dark brown costal streak, reaching beyond the fold; on the middle of costa is a large, triangular spot, reaching to the lower edge of the cell; at the end of the cell is a small, moon-shaped, dark brown spot; just before termen and parallel with it is a broad, dark brown fascia, and between it and the discal spot is a narrower, less pronounced and slightly convex, dark brown fascia; cilia dark brown with lighter tips. Hindwings dark brown- ish fuscous. Abdomen dark brown above with each joint tipped with silvery white. Underside of body silvery white. Legs silvery white, barred and annulated with dark brown. Alar expanse.—11-12 mm. Habitat—Paraiso, Porto Bello, Trinidad River, and La Chorrera, Panama, February—May. Type-specomen.—Cat. No. 15818, U.S.N.M. This species is very close to Anacampsis siderophaea Walsingham, but differs in the darker and more pronounced wing ornamentation and the lighter legs and body. A. siderophaea Walsingham has the abdomen uniformly dark brown above, without the silvery white crosslines possessed by the present species. ANACAMPSIS LAGUNCULARIELLA Busck.

Second joint of labial palpi and base of third black, iridescent; upper four-fifths of terminal joint white. Antenne black, with basal fourth and extreme tip white. Face smoky; head and thorax whitish ochreous. Forewing whitish ochreous with a large, blackish brown, oval, dorsal spot, occupying more than a third of the wing space, beginning near the base and reaching to apical third of the dorsal edge and beyond the middle of the wing; apical part of the wing largely occupied by a strongly iridescent pearly area before and after which the wing is shaded with brown; apical third of costa blackish brown with a short, oblique, ochreous streak before a tri- angular apical spot; three short, black, longitudinal streaks on the terminal edge; cilia white with a brown line parallel to the wing edge. Hindwing dark fuscous with whitish costal edge. Abdomen dark fuscous with ochreous anal tuft and a series of lateral ochreous spots. Legs light ochreous with broad black bars on tibize and tarsi. Alar expanse.—13-14 mm. Habitat.—Trinidad River, Porto Bello, and La Chorrera, Panama, April, May, and June. Type-specimen.—Cat. No. 15819, U.S.N.M. I have tried to identify this species with fuliginosa Felder and Rogenhofer, which, according to the figure, is very similar, but deem it safer to keep it under a separate name. ANACAMPSIS PHYTOMIELLA, new species. Second joint of labial palpi blackish green on the outer surface, whitish at apex and on the inner side; terminal joint with basal half white, except for a broad, dark green annulation and with outer half golden brown; extreme tip black. Head and thorax dark olive green; face a shade lighter green. Forewing dark green, mottled with light ocherous and blackish brown scales; on the middle of the costal edge is a black spot and at apical third is a similar spot; from both of these run faint, irregular, darker green, zigzag fascie across the wing out- wardly narrowly edged with ocherous; scattered irregularly over the wing are small tufts of blackish brown, raised scales and around apical and terminal edge is a subterminal row of black dots. Hind- wings dark blackish brown; darkest and nearly black towards the tip; costal edge above vein 8 silvery white. Abdomen blackish brown above, greenish fuscous below. Legs greenish brown with narrow, white annulations on the tarsal joints. Alar expanse.—18-19 mm. Habitat—Alhajuela, Cabima, and Porto Bello, Panama, March- June. Type-specimen.—Cat. No. 15820, U.S.N.M. no. 2048. NHW MICROLEPIDOPTERA FROM PANAMA—BUSOK. 9 (2 A very good example of protective coloration. 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 again 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 making 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 joint and the terminal joint whitish ocherous with a black dot just before the tip. Antenne ochreous with dark brown annulations. Face, head, and thorax light ochreous fuscous. Fore- wings light ochreous fuscous with white and blackish brown markings; costal edge with three blackish markings, one from base to basal fourth with a smaller projection obliquely outward, one an obliquely out- wardly directed streak on the middle and the third a large spot cover- ing apical third of the costal edge but interrupted by a thin, white, transverse, outwardly angulated fascia across the wing at apical fourth and by two, small, perpendicular streaks beyond this fascia; at the angle of the fascia is a narrow, longitudinal, black streak; apical edge with a marginal, black streak; cell and dorsal part of the wing mottled with several, irregular, small, blackish brown spots. Hind- wings dark fuscous. Abdomen dark fuscous with light ochreous underside. Legs fuscous; tarsi blackish brown with the tips of the joints ochreous. Alar expanse.—8-9 mm. - Habitat—Alhajuela and Cabima, Panama, April, May. Type-specimen.—Cat. No. 15822, U.S.N.M. It reminds one in coloration and pattern of the North American Aproerema nigratomella Clemens. 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 bistrigella; the second and third separated only by a thin, white streak; there is only one whitestreaklet 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.

Second joint of labial palpi light gray with blackish apex; terminal joint white with a broad, black band just below the tip. Face whitish gray. Head and thorax dark gray. Forewings dark gray, finely irrorated with minute greenish ochreous dusting; outer half of costal edge with an oblique, white streaklet at apical third and a per- pendicular, white streaklet just before apex; this latter nearly con- nects with a thin, perpendicular, white line across the wing, outside of which the tip of the wing is light gray with a single black longitudinal dash and a broad black marginal line narrowly edged with yellow. Hindwings dark brownish fuscous with basal half of costa silvery white. Abdomen dark fuscous above, silvery on the underside. Legs silvery gray; the tarsi blackish with narrow ochreous annulations.

Bred by Mr. Urich from the pods of Crotolaria. There has been for many years aspecimen of this species in the United States National Museum, bred by Dr. H. G. Dyar from pods of ‘‘woman’s tongue,” Acacia? 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 synoptic tables I recognized in his Paraspistis ioloncha, 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 Walsingham, 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 Hitbner.

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, Cratomorphus 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.

Family STENOMIDA. Genus CATARATA Walsingham. Type.— Catarata lepisma Walsingham. In the definition of this genus in the Biologia Centrali-Americana it is stated that vein 4 is out of the stalk of vein 2+3 in the forewings. This, however, is not the case in either of the two species described, the type C. lepisma Walsingham and C. stenota Walsingham. With the evidence of additional material the specific identity of these is apparent; the species is quite. variable; stenota 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. obnubila, the veins are as described by Lord Walsingham. These modifications, which in any of the higher families, Gelechiide, Oecophoride, or Cosmopterygide, would be definite and sound grounds for generic differentiation, I do not consider of such value in the generically far less crystalized family Stenomide. 36 PROCEEDINGS OF THE NATIONAL MUSEUM.

Athleta WALSINGHAM, Biologia Centrali-Americana, vol. 4, Heterocera, 1912, p. 155. Type.—Athleta trisecta Walsmgham. In the description of the genus Athleta vein 2 of the forewing 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 Trinided River, Panama, it is found that this character is not stable within the spe- cies, but that vein 2 may be separate, connate, or even short stalked with vein 3. Similar instability of these veins within the species is found in other groups of this family and makes the character of little value generically. The genus Athleta may, however, be separated from its nearest ally, Catarata Walsingham, by the anastomosis of veins 2 and 1c, which appears to be constant; from whatever start- ing point vein 2 runs nearly at right angles downward and into vein 1c, 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.

It is recorded from French Guiana, Para, Brazil, and from the Canal Zone, Panama. The larva is a case maker and feeds in silk-lined galleries in Polyporus. ARRHENOPHANES CHIQUITA, new species. Male.—Labial palpi light ochreous, tinged with brown. Tongue absent. Antenne finely ciliated throughout. Face and head ochreous. Thorax ochreous, mixed with dark brown; posterior tuft long and thin. Basal two-thirds of the forewings golden brown suffused with dark burnt brown; an indistinct, oval, light ochreous spot on the middle of the fold edged with black; a larger, quadrangular, whitish ochreous spot at basal third of costa; at the end of the cell an indistinct group of black scales and base of costa darker than the rest of the wing; apical third of the wing, rather sharply separated from the basal dark part, is covered with large, circular or oval, whitish, semitransparent spots, with the narrow intervals light golden brown; cilia white with a dark brown pencil at apex and with tornal part blackish brown.

Abdomen and legs golden yellow; claspers and uncus very long, nearly a third of the abdomen. Alar expanse.—12 mm. Habitat—Cabima, Panama. Type-specimen.—Cat. No. 16766, U.S.N.M. 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 ae genera, which, how- ever, are closely related. Geesaces is also a fungus feeder, according Zeller, on Boletis arborum. Family TINEIDA. HARMACLONA, new 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. Antenne in the males very short, bipectinate; in the females somewhat longer, but less than half the forewing; thickened with scales; simple. Face and head clothed with erect scales. Fore- wings long, narrow; costa and dorsum straight, parallel; apex bluntly pointed, termen oblique; 12 veins; 2 from outer fifth of cell; 3 and 4 approximate from end of cell; 7 and 8 stalked, both to costa; 11 from before middle of cell; internal veins prominent, one from between 10 and 11 to between 6 and 7, another from base to vein 5.

Pos- terior tibiz with long loose hairs above. The short, pectinated male antenne and the strong internal veins as well as the robust body and the sparse scaling remind strongly of the family Cosside. HARMACLONA COSSIDELLA, new species. Labial palpi white, sprinkled with reddish brown. Face and head reddish white sprinkled with brown. Antenne dark brown with slight fugitive white scaling in the male.

Thorax black. Forewing light ochreous suffused with brown and black; entire costal edge broadly black; a round black dot at the end of the cell; the area between this dot and tornus strongly mottled with black and dark brown; a small black dot at the base of dorsal edge; entire wing irregularly sprinkled with single black and brown scales; cilia light ochreous mottled irregularly with black. Hind- wings dark brownish fuscous with lighter ochreous cilia. Abdomen dark brown. Legs dark brown; tarsi broadly annulated with black.

NEW MICROLEPIDOPTERA FROM PANAMA—BUSCK. 65 Genus SCARDIA Treitche. Type.—Scardia boleti Fabricius. SCARDIA ISTHMIELLA, new species. Labial palpi ight ochreous brown on the inner side, blackish brown exteriorly. Face and head light ochreous brown; vertex touched with blackish brown. Antenne ochreous. Thorax blackish brown; tips of patagina ochreous. Forewing dark bluish brown overlaid with black and with strong golden and iridescent reflections; costal edge with small, indistinct, geminate, ochreous spots, hardly discernible on basal half, more distinct on apical third; a broad, light, ochreous area along termina] edge sprinkled with black and brown scales; the ochreous space reaches from just before apex on the costal edge to apical third of dorsum; the edge toward the basal dark part is undulat- ing; a black projection at the end of the cell encroaches upon the light part and just below the light part projects into the dark area; a series of small, dark brown dots along the apical and terminal edges. Hind- wings dark purplish brown, with yellowish cilia. Abdomen dark brown above, light ochreous on the under side. Legs ochreous, strongly barred with blackish brown exteriorly. Alar expanse.—30 mm. Habitat.—Porto Bello, Panama, March. Type-specumen.—Cat. No. 16769, U.S.N.M. A large, typical, narrow-winged species, close to S. coloradella Dietz, but without any dorsal ochreous markings. SCARDIA MINIMELLA, 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. asthmella. 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 scales. 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. Hindwings 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 ochreous 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 forewings. 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 —Althajuela, Cabima, Trinidad River, Tabernilla, Paraiso, and Corozal, Panama. April, May and June. Type-specumen.—Cat. 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. Labial palpi dark grayish brown, very long, slender, overarching the head but held rather erect; each joint thickened with scales toward the tip; in the third joint these apical scales form a small free brush, no. 2043.

By Mary J. Ratupun, 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: Varuna altimana. Ptychognathus guijulugani. Sesarma (Sesarma) palawanense. Sesarma (Sesarma) vicentense. Sesarma (Sesarma) mindanaoense. Sesarma (Sesarma) edwardsi philippinense. Sesarma (Sesarma) xquifrons. Sesarma (Sesarma) tectum. Sesarma. (Holometopus) limbense. Sesarma (Parasesarma) dumacense. Sesarma (Parasesarma) moluccense jamelense. Sesarma (Parasesarma) pangauranense. Macrophthalmus sandakani. Dotilla sigillorum. Tympanomerus philippinensis. The genus Varwna' is expanded to include those species of Ptychognathus 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 wrist 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 Varuna resemble Ptychog- nathus in having the exognath wider in the male than in the female. 1 Milne Edwards, Dict. Class. Hist.

VARUNA ALTIMANA, new species. Type-locality Point Jamelo, Luzon; river, in 20-foot seine; July 13, 1908; 1 male. Type.—Cat. No. 44558, U.S.N.M. Dimensions.—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 bebind 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 margins 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 margins moderately convergent, 3 teeth acute, with straight sides and separated by deep, narrow sinuses. Postero- lateral margins subparallel, slightly sinuous; a granulated line, beginning a little ways from the margin and considerably behind the last lateral tooth, forms the upper boundary of the very short and broad obliquely-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 wide as the ischiognath. Chelipeds 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 swollen, posteriorly rugose; upper margin compressed and elevated in a flat lobe occupying the proximal two-thirds; fingers 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—RATHBUN. 71 sinus in the prehensile margin near the tip, teeth 9-11; dactylus 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 maxilliped (exognath wider, and ischiognath not widening distally), a longer, slenderer carpal spine, a lobe on upper margin of hand, a gape between the fingers. V. 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. Type-locality.—Guijulugan, Negros; April 2, 1908; 2 males, 2 females, adult (1 female ovig.). Type.—Cat. No. 44668, U.S.N.M. Dimensions.—Length of largest male, 8 mm., width 9.3 mm. Length of ovigerous female 8 mm., width 9 mm. Associated with P. barbata at Guijulugan, were four specimens of a closely allied species. Carapace a little broader than long, flat, regions indistinct; post- frontal tubercles well marked; the oblique portion of the branchial region is separated from the horizontal portion by a fine granular line in the posterior half. Front sinuous, prominent, half as wide as greatest width of cara- pace; edge without a line of granules. Antero-lateral teeth 3, blunt, the first or orbital tooth the longest, the last tooth very small; teeth not projecting sideways, sinuses triangular. Upper border of orbit sinuous and oblique. The antennules fold nearly transversely. Epistome very narrow, almost linear; posterior border crenulate. 1 Ptychognathus affinis de Man, Zool.

Exognath broader than ischiognath 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 paim, 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 wrist 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 fingers; near the tips there is on the inner and outer surfaces a row of short hairs 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 three- fourths times, the last pair one and one-fourth times, the length of the carapace. Differs from P. barbata' 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 barbata; 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 barbata (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.

No. 2044, NEW PHILIPPINE 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 sinuses, of which the median is much larger than the lateral; submedian Iobes more than one and one-half times as wide as outer lobes. Surface of front very much as in S. teniolatum White,’ being concave and smooth except for a few tubercles; lower margin very sinuous. Upper margin of orbit long and sinuous and directed backward to the orbital tooth. Upper margin of merus of cheliped 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 lines 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 line of smaller granules extending from the articulation with the carpus to the tooth at the distal end of the upper margin; no pronounced transverse elevation on inner surface of palm, 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 half 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 third 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 third 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. teniolatum from which it differs in its longer and narrower carapace; narrower front; in the greater difference in the width of the outer and inner frontal lobes; in the granulate, not pectinate, ridge near the upper margin of the palm, which is closer fo that margin and not straight but follows the slight curve of the margin; and in the absence of a transverse ridge inside the palm. 1 Alcock, Journ.

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 teniolatum and lafondw. The latter has an even broader carapace than teniolatum, and its side margins are parallel instead of convergent. SESARMA (SESARMA) VICENTENSE, new species. Type-locality.—Port San Vicente (Luzon side), Palaui Island, off northern Luzon; beach; Nov. 15, 1908; 1 male. Type.—Cat. No. 45758, U.S.N.M. Dimensions.—Male, length 8.8 mm., width at orbital angles 9.2 mm., posterior or greatest width 9.7 mm., width of front 4.6 mm. A small, square species with 3-toothed side margins and a vertical front. Carapace a little wider than long, sides nearly parallel but slightly diverging posteriorly, and a little concave behind the third tooth; dorsal surface almost flat, except near the front and postero- lateral corners; regions delimited, surface roughened with crowded flattened granules anteriorly and with confluent grooves and pits posteriorly; on the hepatic and anterior branchial regions there are also unequal bead-granules. Suprafrontal lobes nearly transverse, separated by very small emarginations, the lobes of the inner pair a little more than one and one-half times as wide as those of the outer pair; from these lobes the front descends abruptly, lower margin horizontal, sinuous with two broad, shallow lobes and an equally broad median sinus; sides of front parallel, lower corners rounded, surface finely granulous, a tubercle on each side near the lower margin almost in line with the notch between the outer and inner postfrontal lobes. Upper margin of orbit inclined obliquely backward and outward to the acutangled antero-lateral tooth; this is separated by a well- marked notch from the second tooth which is small and obtusangled; the third tooth is simply a smooth swelling of the margin. Epistome covered with vesicular pubescence. Merus of outer | maxillipeds equal in length to the ischium, its antero-lateral angles rounded off. Only the left cheliped is present and that is rather small, not one and one-half times as long as the carapace. Lower and inner margins of merus denticulate, outer surface covered with short ruge, upper margin formed by parallel, oblique rugee. Upper surface of carpus crossed by granulated ruge, inner angle bluntly rounded. Outer surface of hand nearly smooth, punctate, upper surface covered with sharp granules, and near the margin, with obliquely longitudinal and 1 Voy. l’ Astrolabe, Atlas of Zoology, Crustacea, 1852 (?), pl. 6, figs. 4 and D.

The fingers do not gape when closed, although the irregular teeth do not fit snugly together; the upper margin of the dactyl bears 6 spinules on the proximal half. Merus joints of legs diminishing toward both ends, upper surface roughened with fine granules, anterior margin with a short subdistal tooth tipped with a back bristle, merus of third pair about two and three-fourth times as long as wide. Last three joints narrow, bor- dered with dark bristles; dactyli nearly straight till near the tip, a little longer than their respective propodi. In the male abdomen the margins are concave from the beginning of the fourth to the beginning of the sixth segment; terminal segment large, as wide as long, and as wide as the adjoining end of the sixth segment. This species is most nearly related to 8. sinense Milne Edwards.!_ It differs from sinense in its narrower front, only half as wide as the dis- tance between the orbital angles, in having a third tooth on the side margins, in the middle part of the outer surface of the palm being nongranulate, and in the absence of a transverse granular line on the inner surface.

Distinguished by the slightly marked frontal lobes and the well- defined upper surface of the palm. Carapace sensibly wider than long, wider anteriorly than poste- riorly, widest at the single epibranchial tooth, lateral margins a little concave; surface everywhere punctate, mesogastric region defined, as is also the posterior cardiac lobe; oblique lateral lines few, about seven, the anterior of these crossing the epibranchial tooth. Front very wide, widening below, superior lobes separated by shallow fur- rows, the lateral ones very short; outer lobes a little narrower than inner; surface of front nearly vertical, lower margin arcuate, although nearly straight at the middle. Upper margin of orbit directed very obliquely backward to the short and slightly advanced orbital tooth, next tooth subrectangular. Maxillipeds widely gaping, the merus joints obliquely transverse. Chelipeds of male unequal; outer surface of arm, wrist, and proximal half of palm crossed by fine granulated rugze which on the middle of the palm are longitudinal; no spine on upper margin of arm, only a blunt angle; inner margin sparingly denticulate and with a shallow rounded prominence; no tooth at inner angle of wrist; chele punc- tate; upper surface of palm flattened, limited outwardly by a smooth blunt ridge and inwardly by an uneven granulated margin; a trans- verse line of granules inside palm, otherwise surface nearly smooth. Fingers moderately gaping; the horny extremity embraces the sub- terminal tooth on each finger; upper margin of dactylus with a line of four distant spinules; lower margin of immovable finger straight except at tip; prehensile edges irregularly toothed, three teeth on each finger enlarged. Ambulatory legs of moderate length; carpal and propodal segments densely hairy. Abdomen of male narrow, with a large terminal segment which is nearly as wide as long. Resembles the very briefly described S. lave A. Milne Edwards ! in its smooth shining carapace, but the carapace is narrower than in leve (where it is 7 mm.

This crab is densely covered with pubescence everywhere except on the cornex, 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 pair 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 prominent 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. Merus with a subter- minal tooth on upper margin, and a slight prominence but no tooth on the inner margin. Outer surface of carpus covered with low tuber- cles; inner angle blunt. Chele, when hair is removed, smooth and shining, without ornamentation in the way of granules or lines but with two or three depressed and inconspicuous tubercles on upper surface, and fine puncte in a reticulating pattern where the hairs are inserted; upper margin of palm blunt; lower margin of propodus nearly straight; fingers slender, prehensile edges finely toothed as far as to the horny extremities which occupy the distal third and are slightly notched where the tips cross each other.

Terminal segment of abdomen of female inserted up to its middle in the sixth segment. S. tectum, in the absence of rugose lines on the postero-lateral por- tions of the carapace, in the shining surface, lack of roughness or granulation, coat of sete and hairs, resembles S. lanatum Alcock,* but the latter has a considerably wider carapace, with the tufts of hair smaller, more numerous and more uniform. SESARMA (HOLOMETOPUS) LIMBENSE, new species. Type-locality—Limbe Island, Gulf of Tomini, Celebes; November 12, 1909; 1 male (type), 2 females (1 ovigerous). Type.—Cat. No. 45920, U.S.N.M. Dimensions.—Male type, length of carapace 6.8 mm., width at antero-lateral angles 7.7 mm., width at postero-lateral angles 7.2 mm., width of front 4.4 mm.; ovigerous female, length of carapace 11.7 mm., width at antero-lateral angles 12.9 mm., width at postero- lateral angles 12.7 mm., width of front 7 mm. Carapace deeply sculptured; not only are the interregional grooves deep, but the grooves separating the postfrontal lobes are continued halfway to the mesogastric region, and the branchial region shows several areolets along itsinner 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 slightly sinuous, and in front view, arcuate as well; a bunch of coarse granules near the middle of either half. Postfrontal lobes somewhat oblique, outer pair slightly nar- rower than inner pair. Arm without spine above; inner margin with a triangular tooth denticulated on the edge. Palm rather smooth, sparingly punctate, with fine rugz near the wrist and sparse granules near the top; upper margin a single slightly angled, granulated line running 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- form tubercles in the male; in the female the tubercles are low and only 5 or 6 proximal ones are discernible. 1Journ. Asiatic Soc.

Legs long and narrow, the third pair more than twice as long as the carapace, and its merus 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. SESARMA (PARASESARMA) DUMACENSE, new species. Ty pe-locality.—_Dumaca River, Luzon; February 25, 1909; 1 female, thin-shelled. Type.—Cat. No. 45922, U.S.N.M. Dimensions.—Type female, length of carapace 13.2 mm., width between antero-lateral angles 17.6 mm., width between postero- lateral angles 15.7 mm., width of front 9.8 mm., length of propodus of cheliped below 7.9 mm., same above 3 mm., height of same 3.4 mm., length of merus of second leg 10.7 mm., width of same 4.8 mm. 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 separating 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 oblique ridge running near the side of the cardiac and intestinal regions. The lateral margins of the deflexed front converge below, while in plicatum 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 plicatum; on the upper surface of the palm there 1s a pectinated ridge beginning at the distal inner angle of that surface and running in a longitudinally oblique 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 tuberculiform distal portion.

This form differs from typical moluccense de Man,' in having the carapace a little narrower in proportion to its length; in the front also narrower in proportion to the width between the antero-lateral angles; in the 9 or 10 tubercles on the upper margin of the movable finger being obliquely transverse instead of longitudinal, each tubercle trending forward or distally toward the inside of the finger, as in S. lenzit de Man.? As in the typical species, the carapace is widest at the anterior angles; the surface of the front bears an elongated transverse tubercle near the lower margin on either side of the middle, and a round tubercle underneath the outer corner of the postfrontal lobes of the inner pair; the upper margin of the arm has no subdistal spine, only an obtuse tooth, the lower margin has a triangular expansion with denticulate border, and a spine or sharp tooth at the angle; the upper surface of the palm has two oblique pectinated ridges sub- parallel to the posterior margin, the ridges being prolonged back- ward by simple granulated lines toward the articulation with the carpus; in the female the ridges are more longitudinal; the merus joints of the legs bear a sharp spine on the upper margin; the abdomen of the male is shaped as in S. lenzii.2 SESARMA (PARASESARMA) PANGAURANENSE, new species.

The lateral margins of the carapace are slightly concave behind the acute antero-lateral spine; the upper margin of the orbit is long and sinuous; the surface is coarsely punctate, and on the anterior part, single coarse bristles proceed from some of the puncte. Front high, about one-fourth its width, sides parallel, lower margin most produced downward at the middle. Outer postfrontal lobes scarcely more than half as wide as inner ones, their anterior margin being continued downward toward the lower outer angle of the front. Arm without subdistal spine on upper margin, but with a trian- gular spine on inner margin. The outer surface of the palm has a microscopic granulation and is coarsely and sparsely punctate; on the upper part there are a few larger granules; the upper surface is crossed by three irregular longitudinally oblique ridges subparallel to the posterior margin. Inner surface of palm without transverse ridge. The upper margin of the finger has a row of very small and low tubercles, of which there are about 11 on the proximal half; on the distal half no tubercles are perceptible. Legs slender, especially in the last three segments; the merus joints have no subdistal spine above, but only a right-angled tooth; the dactyli are long and straight to near the end. Color.—The carapace in alcohol is dark, and the legs are cross- banded with dark; on the propodal segments there are two dark bands. This little species, for the mature female is only a quarter of an inch wide, has much in common with S. calypso, in which, however, the front is wider and lower, the meropodites of chelipeds and legs have a superior spine, the meropodites of the legs are wider and the dactyli more curved.

Carapace very convex, short and broad, nearly smooth, and naked; a broad furrow on the front is continued across the gastric region; from each side of the mesogastric region a deep narrow groove runs back on the branchial region to a point opposite the cardiac region, where it turns outward and forward, forming a loop. Orbit shallow, oblique, its upper limit indicated only by a fine smooth rim as far as the tooth at the outer end; this last is very obtuse-angled and bounded posteriorly by a shallow notch. The orbit is on a much lower level than the apparent margin of the cara- pace; this margin is partially indicated by a very fine granulated line, which is present above the middle of the ocular peduncle, and also about the antero-lateral angle. There is a similar granulated line above the postero-lateral margin and the base of the last leg. Sides of the carapace vertical and horizontally grooved. Front narrow, deflexed vertically, lateral margins convergent, slightly hollowed at base of eye-stalks, extremity broadly triangular; surface smoothly elevated along the sides, a circular elevation in the center of the broad median furrow.

EULEPIDOTIS JUNETTA Dyar.! This species from Tabernilla, Canal Zone, Panama, will be more fully described in a forthcoming report dealing with the results of the Smithsonian Biological Survey of the Panama Canal Zone. EULEPIDOTIS MAGICA, new species. Dark slaty brown, finely peppered over thorax and fore wings, the scales having bright tips as in sabina Bar, shading to orange brown over apex; three lines of metallic green, the inner bent subcostally, then slightly oblique, followed by brown; mesial line more oblique, lost below the subcosta except for a faint dark trace; outer line oblique above, less so below vein 5, running to tornus, preceded by orange at costa; a leaden subterminal lne. Hindwing nearly black, with- out tail; three blue spots in a row along submedian fold, the middle one black outwardly, the outer marginal one nearly all black, raised; a slight black prominence on margin above this last,spot. Expanse, 23-25 mm. Cotypes.—One male, one female, No. 15697, U. S. Nat. Mus.; St. Jean and St. Laurent, Maroni River, French Guiana, October and November, 1904 (W. Schaus). EULEPIDOTIS DIVES Butler.

I have three specimens of this from French Guiana. EULEPIDOTIS SUZETTA, new species. Yellow, unusually clear; lines straight, dark ocherous, edged on one side by a fine brown line, on the other by a broad band of metallic bluish scales ; inner line with colors reversed; mesial line more oblique than the others; a subterminal leaden line preceded by a brown line. Hindwing clear yellow; a rounded metallic blue spot on submedian fold, well before margin, at about outer third of wing; on the margin three silvery patches, marked by a few brown scales, the lower one opposite the submedian patch is the largest. Expanse, 24 mm. Type.—Male, Cat. No. 15698, U. S. Nat. Mus.; St. Jean, Maroni River, French Guiana, April, 1904 (W. Schaus). The specimen bears a label “corinna Cr., fide B. M.’’; but Bar’s identification must be respected since Cramer’s figure is so poor as to be uncertain if considered alone. EULEPIDOTIS STELLA Bar. Palindia stella Bar, Ann. Soc. Ent. France (5), vol. 5, 1875, p. 297. I have no specimens of this species, which seems very distinct, judging from Bav’s figure. EULEPIDOTIS CORINNA Cramer. Phalena Noctua corinna CraMER, Pap.

I have specimens from Trinidad, British and French Guianas, and Venezuela. EULEPIDOTIS PRISMATICA, new species. Dull ocher, shaded with sordid nearly all over the wings; lines double, the centers dull ocher, inner line blackish, outer metallic violet, but appearing dark leaden in most lights, inner line reversed; both mesial and outer lines bent more or less in the middle; reniform a dusky shade; submarginal line leaden; terminal row of dark dots. Hindwing with costa smoky, disk only dull orange; a curved streaked band with violet scales across disk; three silvery patches on margin preceded by black dots. Beneath rather uniformly light ocherous straw color. Expanse, 20-24 mm. Cotypes.—One male, two females, Cat. No. 15699. U. S. Nat. Mus. St. Jean, Maroni River, French Guiana, July, 1904 (W. Schaus). Close to corinna Cramer, but, I think, distinct. It is generally duller, less contrastingly colored, and beneath the uniform light ocherous tint is different from the bright yellow contrasted markings of corinna. 102 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47. ee ee EULEPIDOTIS TRANSCENDENS, new species. Thorax, basal segment of abdomen, and basal space of fore wing pale glaucus green; fore wing lilacine brown, apical half yellow, form- ing a clear wedge on costa before outer line and a blotched area at apex; lines broad, double, orange filled, slender inner line dark brown, outer broad, metallic blue; subterminal line silvery; fringe dark. Hind wing nearly solidly fuscous; a yellow area in fringe below apex and at tornus; patch on submedian fold metallic blue, followed by minute lines to the silvery marginal patches, the lower of which has its black dots fused into a crescent. Expanse, 25-27 mm. Cotypes.—Two males, one female, Cat. No. 15700, U.S. Nat. Mus.; St. Jean, Maroni River, French Guiana, July, 1904 (W. Schaus). This species is abnormal in lacking entirely the hind tibial tufts of the male. EULEPIDOTIS PENUMBRA, new species. Dark brown; forewing rather roughly scaled, apex yellowish; lines double but rather narrow, curved, orange brown, but slightly relieved from the ground; metallic edges blue, narrow, that of midline obso- lete below subcosta; subterminal line leaden. Hindwing with clear yellow apex, involving the fringe, the rest of the wing of color of forewing, shading to blackish on costal half; two raised patches of scales on submedian fold, with blue metallic tint, the outer one mar- ginal and followed by a second smaller spot above; a dark line from subcostal dark region to inner submedian spot. Expanse, 27 mm. Type.—Female, Cat. No. 15701, U.S. Nat. Mus.; St. Jean, Maroni River, French Guiana, March, 1904 (W. Schaus). EULEPIDOTIS REGALIS Butler. Phrygionis regalis Butter, Trans. Ent. Soc. Lond., 1879, p. 31, note. I have one specimen from French Guiana, identified by Schaus. EULEPIDOTIS SELECTA, new species. Forewing brown over orange under tint, which appears subapically in a triangular diffused area; lines orange brown, with slender dark inner edges and metallic blue outer ones (inner line reversed), mner and mesial lines straight, the mesial more oblique; outer line curved in upper half; subterminal line silvery; terminal dots black. Hind- wing fuscous brown, a ght patch near apex; disk with a reddish area, followed by a metallic blue band, then an area of black irrorations; three marginal silvery elongate patches with black dots. Beneath contrastingly marked, orange-yellow and fuscous, the apex of fore- wing broadly fuscous; hindwing with two streaks on costa. Expanse, 27 mm. Type.—Female, Cat. No. 15702, U. S. Nat.

The description of superior is without locality; dewitzii is from Porto Rico and deva from Mexico and Panama. I have a long series from Mexico, Costa Rica, and Venezuela, none from the Antilles, though Méschler’s description leaves no doubt of the identity of dewitzii. The species varies considerably in shading. Generally the ground color is uniform, but occasionally the terminal space is paler and without the purple shading, and again it is markedly darker than the rest of the wing.

THE GENERA PALINDIA AND DYOMYX—DYAR. 105 EULEPIDOTIS SYLPHA Dyar. This will be more fully described in my fourth paper on Mexican Lepidoptera to be published in the present volume of the Proceedings 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, slightly widened and luteous filled on costa, ’ converging a little in the direction of tornus; costal area of hind 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 interlined with green and tipped with brown. Beneath greenish, washed over with brown; two curved brown lines on fore wing. Expanse, 2/7 mm. Cotypes.—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; lines 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 line 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 hind tibize 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 cotypes, both females from Mexico, are before me. EULEPIDOTIS CROCEIPARS, new species.

This species is not before me, but should be readily recognizable from Bar’s excellent figure. EULEPIDOTIS ERINA, new species. Green; abdomen green above at the base, fuscous posteriorly. Fore wing mossy green; three crossbands double, brown-filled, wavy or subcrenulate, close and all terminating perpendicular to inner margin, curved on costal half; inner line angularly bent in the middle; a fourth wavy shaded subterminal line; a row of irregular blotches through cell outwardly to margin; a row of terminal white dots; fringe brown. Hindwing blackish fuscous; a green ray before submedian fold and triangular patch on margin beyond it, containing a blackish speck; a narrow outer curved line running near margin toward tornus. Beneath shaded with fuscous brown, especially outwardly; both wings with two curved fuscous bands. Expanse, 27 mm. Type.—Female, Cat. No. 15708, U.S. Nat.

Ihave five specimens from there, one from Costa Rica, one from Panama, and two from Venezuela. Possibly it is not more than racially distinct from hebe Méschler of the Antilles. The two are certainly very close. EULEPIDOTIS HEBE Mischler. Palindia hebe MiscuteER, Abh. Senck. Nat. Ges., vol. 14, 1886, p. 195. Eight specimens are before me from Cuba. No. 2046.

Closely allied to hebe, apparently a degenerate offshoot from it. The colors are dulled and very variable, the white costal ornamen- tation obsolete, the markings of hind wing reduced. I have five specimens from Cuba. EULEPIDOTIS PERDUCENS Walker. Palindia perducens WALKER, Cat. Brit. Mus., Lep. Het., part 15, 1858, p. 1767. Described from Jamaica. I have no specimens.

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

This species varies in the amount of purple shading. In typical juncida there is none, except in the terminal space; it gradually increases as a general smoky suffusion of the pale parts until the wing is wholly and uniformly shaded (var. mabdis). Walker appar- 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 Guenée, which he 1Cat. Brit. Mus., Lep. Het., part 12, 1857, p. 850. 108 PROCEEDINGS OF THE NATIONAL MUSEUM. vou, 47. refers to as unknown to him. Butler also recognized the variation, but went a step too far by including also julianata Stoll. I have 135 specimens before me from Brazil, the Guianas, Venezuela, Panama, Costa Rica, and Mexico.

I have four specimens before me from Ecuador, Colombia, and Costa Rica. Dr. A. S. 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. Shining white; abdomen duil 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 margin, preceded by a black spot with white dash on one side and marginal white line on the other, preceded by a brownish area with scattered black scales, and before this a very short brown line at end of outer white ray. Expanse, 40-44 mm. Cotypes.—T wo males, one female, Cat. No. 15709, U.S. Nat. Mus.; Rio Janeiro, Brazil (Schaus collection); Omai, British Guiana (Schaus collection); Juan Vinas, Costa Rica, February (W. Schaus). Near dominicata Guenée, but distinctly larger and the ornamenta- tion of the hind wing different. EULEPIDOTIS DOMINICATA Guenée. Palindia dominicata GUENEE, Spec. Gen., vol. 6, 1852, p. 276. 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 Guenée. Palindia persimilis GuENEE, Spec. Gen., vol. 6, 1852, p. 276. I have a single specimen from Brazil, the type-locality. 1 Bull. 44, U. S. Nat. Mus., 1893, p. 361. No. 2046.

This will be described more fully in my fourth Mexican paper. I have six cotypes from Mexico and Venezuela. EULEPIDOTIS ELECTA Dyar.! This will be mentioned more in detail in my forthcoming Panama report. Twenty-six specimens are before me from Venezuela, Panama, Costa Rica, and Mexico. EULEPIDOTIS RECTIMARGO Guenée. Palindia rectimargo GUENEE, Spec. Gen., vol. 6, 1852, p. 276. Thirty-five specimens are before me from Brazil, Paraguay, the Guianas, Venezuela, Panama, Costa Rica, and Mexico. EULEPIDOTIS METAMORPHA, new species. Very similar to rectimargo, differing principally in the direction of the crossband, which runs obliquely from tornus to costa at basal third and is joined completely to the base by the costal dash. Hind wing with the mark fainter, its preceding dash very distinct. Ex- panse, 30 mm. Type.—Male, Cat. No. 15110, U. S. Nat. Mus.; Matanzas, Cuba, November, 1902 (W. Schaus).

This is not before me. Butler makes it a synonym of alabastraria, but none of my series of that species show the little bar close to margin of hind wing seen in Bar’s figure, so I hold the name separate. EULEPIDOTIS HEMILEUCA Guenée. Palindia hemileuca GUENEE, Spec. Gen., vol. 6, 1852, p. 275. One specimen from Brazil is before me. EULEPIDOTIS MICROLEUCA, new species. As in hemileuca Guenée, except that the basal white space of fore wing is filled in with black and brown scales nearly down to vein1. In hemileuca this space is white with a black spot on costa and dot below. Expanse, 29 mm. Type.—Male, Cat. No. 15712, U.S. Nat. Mus.; Rio Janeiro, Brazil (Schaus collection). This may be an aberration of hemileuca, but my series of both forms is so limited that I can form no idea of the range of variation. EULEPIDOTIS VINCENTIATA Stoll.

This is the continental form of modestula Herrich- Schiffer. UNPLACED SPECIES. PALINDIA PRIMULINA Druce. Palindia primulina Druce, Ann. Mag. Nat. Hist., (7), vol. 5, 1900, p. 518. Evidently a peculiar and characteristic species, unlike anything known to me. The following is Mr. Druce’s description: Male.—Head, antenne, collar, tegulz, thorax and abdomen pale primrose-color; the under side of the thorax, abdomen, and legs white. Primaries and secondaries pale primrose-yellow; primaries, the costal margin edged with white, three curved chrome- yellow bands cross the wing from the costal to the inner margin, the first two bands nearest the base, the third beyond the cell; the marginal line white, with minute black dots; the fringe chrome-yellow; secondaries with a few metallic scales near the anal angle, above which is a short chrome-yellow line; the under side of both wings pale primrose-yellow. Expanse, 1 inch. Hab.—Colombia, Valparaiso (Mus. Druce). PALINDIA REFLEXA Herrich-Schiffer. Palindia refleca Herricn-Scuarrer, Corr.-Blatt zool.-min. Ver. Regensb., vol. 22, 1869, p. 154. Easily to be recognized by the very peculiar secondary sexual character of the male, a round, white, hairy lappet on the costa above. I have seen nothing at all approaching such a structure. The following is Herrich-Schiffer’s description: 114) reflexa HS. 489/625. foem.—449/1047 mas.—Kleiner als corinna, Hfl auf R 3 sehr schwach geeckt. Rostbraun, Vfl mit 2 ganz geraden, gegen den IR divergirenden QStreifen, von 1/3 und 2/3 des VR und weisser W der Franzen. Auf den Hfl nur ein weisser Schrigstreif in Z 1 a als innere Begrenzung eines rostrothen Fleckes. Beim kleineren Manne sind beide Streife der Vfl undeutlicher, weniger divergirend, der VR aber hinter der Mitte in einen grossen, halbscheibenférmigen, weissen, rothbraunge- wimperten Lappen nach oben umschlagen. Recently Mr. Schaus and the writer, in considering the identifica- tion of Herrich-Schiffer’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 holophxalis Ragonot, a Pyralid of the subfamily Chrysaugine.

Palindia striatia Herricu-Scuarrer, Corr.-Blatt zool.-min. Ver. Regens., vol. 22, 1869, p. 153. Unknown to Guenée (1852), who placed it in Palindia from his- interpretation of Cramer’s figure. Also unknown to Walker,’ who follows Guenée. Herrich-Schiffer had a specimen from Cuba which 1 Cat. Brit. Mus., Lep. Het., part 12, 1857, p. 850. No. 2046.

NEW GENERA AND SPECIES OF AMERICAN BRACHYRHYNCHOUS CRABS. By Mary J. Ratusun, 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 types of the remaining species are in the United States National Museum. FAMILY GONEPLACID. Subfamily CARCINOPLACIN &. TRIZOCARCINUS,! new genus. Type of the genus.— Trizocarcinus dentatus (Rathbun). Carapace deep, subquadrilateral, broader than long, with 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.

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 Carcinoplaz' of the Indo-Pacific region, but differs chiefly in the form and disposition of the maxil- ipeds, the separation of the front from the orbit, and the presence of stridulating apparatus.

Carapace convex antero-posteriorly and from side to side; surface covered with puncte and fine reticulations; coarser striz cross the anterior half transversely and nearly all the branchial region ob- liquely. Surface of front covered with short strive and minute gran- ulation; free edge arcuate and faintly bilobed, each lobe appearing in front view slightly bilobed; edge a raised finely granulated cim; post- frontal lobes low. Antero-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, coy- 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 Linnzeus, Syst.

Tt Our species resembles Pachygrapsus crassipes Randall! 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 strize 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. Subfamily VARUNIN 4. CYRTOGRAPSUS ALTIMANUS, new species. Plate 4. Type-locality—San Matias Bay, Patagonia; Hassler Expedition. Additional locality—Rio Grande do Sul, Brazil. 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 puncte; 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 deflexed; 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. spectabilis de Man, it seems best to consider it as a distinct species. The fourth tooth of the lateral margin is farther back than in spectabilis 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 SHSARMIN 4. SESARMA (SESARMA) VERLEYI, new species. Plate 6.

Supra-frontal lobes deeply separated, the median groove larger than the lateral grooves; middle pair of lobes transversely arcuate; outer pair narrower, oblique, trending forward toward the orbit. Front relatively broad and low, about 5 times as wide as high, sides vertical, lower margin arcuate in front view, sinuous in dorsal view, surface concave in both directions. Upper margin of orbit nearly straight, up to the short, acute tooth at the outer angle of the orbit.

N., collector, 1859. Type.—Male, Cat. No. 1578, M. C.Z.; 1 male paratype in U.S. National Museum, Cat. No. 22180. Dimensions.—Length of carapace of type male 28.7 mm., width at antero-lateral angles 45.4 mm. This is the Pacific representative of the well-known fiddler crab with narrow front and broad fingers, Uca maracoani (Latreille)?, which is distributed on the Atlantic coast of South America from Cayenne to Rio de Janeiro. U. monilifera is considerably larger than maracoant, as the carapace of a large specimen of the latter measures 22X34 mm. 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 lear and not reaching 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 laminar expansion directed upward, edge arcuate, denticulate. The wrist is more elongate than in maracoami. The tubercles of the palm are few and indistinct. 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 proximal 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 lines; 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 11 have adopted the specific name used by Prof. Louis Agassiz on a Museum label, but hitherto unpublished. 2 Ocypode maracoani Latreille, Hist.

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

The granules 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 with 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 with 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 oblique to the axis of the ridge and subparallel to the lower margin of the palm. When 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. Trizocarcunus dentatus, male type, X 2 Fic. 1. Antero-ventral‘view. . Dorsal view. 3.

HYMENOPTERA 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 isnot constant. All three specimens are smaller than the measurements given by Smith, being only 10-12 mm. MEGACHILE BINOTATA Guerin. Two females. COELIOXYS ABDOMINALIS Gverin. Two females and one male.

GiLpert, 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 in 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, 31; 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 EF. 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 F. bison. It differs from FH. claviger in the shorter, more robust preopercular spine, and from both claviger and bison in the reduced number of rays in the dorsal and anal fins. Ten specimens of £. bison from Puget Sound have the fin rays as follows: Dorsal spines. | Dorsal rays. Anal rays. Vill Ix 11 12 8 9 Specimenstivetecocessosecee 8 2 6 4 3 7 PROCEEDINGS U. S.

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. Kye 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 lme 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. *t + no. 2049. TWO COTTOID FISHES FROM CALIFORNIA—GILBERT. ot ORTHONOPIAS TRIACIS Starks and Mann. Plate 11, fig. 2. Orthonopias triacis SrarKs and Mann, Univ. of Cal. Pub. Zool., vol. 8, 1911, p. 11, fig. 1. This 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. DEER eT6eeAG 2 a Poabs Vo 13. Lateral line with a series of 38 scales, the upper and the posterior margins of which are wholly free and are throughout very finely toothed. In Astrolytes, only a part of the posterior margin is exposed and this is faintly or not at all toothed. In Azyrias, both margins are exposed and are serrulate, though less so than in Orthonopias. Azyrias and Astrolytes are not very well separated, for while Axyrias has typically a simply furcate preopercular spine, occasional exam- ples develop a third tooth, as is always the case in Astrolytes. If this character is disregarded, there is nothing essential to distinguish the two genera. Orthonopias is also very closely related, but may claim a certain distinction 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 partly 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 in 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 line. This species was set aside as new prior to its publication 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, Custodian 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- tuide, Lithosiidee, and Pyralide, will be found unusually well repre- sented, many hitherto undiscovered species bemg 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.—Two 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 wing straighter and even nearer the cell. HYLESIA CRESSIDA Dyar (?). 4. Taboga Island, February and June, 1912 (Busck). The specimens are more rosy than alinda before me from Costa Rica and the fore wing less faleate, agreeing with cressida; but all the specimens are males, and without a female can not be placed with certainty. HYLESIA sp. A. 11. Taboga Island, January, 1911 (Busck); Tabernilla, Canal Zone, May, 1907 (A. H. Jennings). This form lies near pollex Dyar, wmbrata 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 larve, 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 larv, the latter conspicuously different from either of the larvee sent by Mr. Busck. Doctor Darling found the larve on a Cashew tree (Anacardiacez) and bred the adults. The form may be named Hylesia darlingi, new species. Closest to H. poller 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 pollez; discal spots of both wings clouded and more obscure than in poller; abdomen of female without the paler ocherous posterior lateral tufts, the hairs concolorous with the rest of the lateral ones. Type.—Female, No. 16038, U.S.N.M.; Ancon, Canal Zone, April, 1913 (S. T. Darling). Larva.—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 intersegmentally and little specks in the centers of the segments; two joined subdorsal and lateral blotches in segmental incisures, a ring around sub- dorsal horns, spot below lateralis, 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 aod posterior ones but slightly longer and slenderer, none as long as the diameter of the body. no. 2050. LEPIDOPTERA OF THE PANAMA CANAL ZONE—DYAR. 159 tatively labeled by Mr. Schaus as females of his rubrifrons 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 lines slender and distinct; apex very dark with light lilacine spot. It does not agree with anything before me, but description from the single female seems inadvisable. LONOMIA CYNIRA Cramer. 3. La Chorrera, May, 1912 (Busck); Trinidad River, 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 eray dorsally; plateada Dognin is like 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. APISTOSIA JUDAS 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 like ithomia Felder. The species is not ahomaa, 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 entirely absent. Mr. Busck made the following note about the defensive secretion of this species: ‘‘On capture these butterflies, male and female, emit no. 2050.

Dark brown; fore wing with coppery tint, especially in terminal space and inner area; lines 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 line near the margin, dark without, coppery within. Hind wing solidly black-brown. Expanse, 28 mm. Type.—Female, No. 15838, U.S.N.M.; Trinidad River, March, 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 Acronyctine, but vein 5 of hind wing is weak and arises from middle of discocellulars, so that it can not be placed in the Plusiine. MENOPSIMUS CRAMBIFORMIS, new species. Fore wing deep brown; inner line golden yellow, obscure, pro- duced outward in an angle in cell; outer line 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 oblique whitish mark for reniform, joining outer line. Hind wing fuscous, lighter 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 believe it to be the same species as Menopsimus crambiformis. 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 misidentification.

The specimens agree with the types of dacula from French Guiana, except that the brown shading within the outer line is less extensive. This is apparently a distinct species and not a race of Jf. dasarada Druce. MICRATHETIS TECNION, new species. Somewhat smaller than dacula and more sharply marked; middle line not so strongly oblique, bent a little at the black punctiform reniform, preceded by a slight brown shade; subterminal line oblique from apex, where it is marked by a black dash; terminal series of minute points. Hind wing pale, with slight yellowish tint, paler than in dacula, not so white as in dasarada. Expanse, 13 mm. Cotypes.—Six males, two females, Cat.

Allied to @. emessa Druce, but lighter colored and smaller. Hind wing palestraw color, shaded with reddish brown on margin. Fore wing paler than in emessa, the basal space rosy violet, the shading on inner half of median space olive brown; outer line excurved in the middle. Expanse, 27 mm. Cotypes—Two females, No. 15845, U.S.N.M.; Alhajuelo, April, 1911 (Busck). Also a male and two females from Aroa, Venezuela (Schaus collection). CLOSTEROMORPHA RUFIFACTA, new species. Similar to C. reniplaga Felder; the large costal patch is brown-red, ending in black outwardly; the ground color is suffused with reddish; the lines are faint, the outer bent at an obtuse angle; the discal marks small, faintly pale ringed. Expanse, 30 mm. Cotypes.—Two females, No. 15858, U.S.N.M.; Trinidad River, March and June, 1912 (Busck). A male of this form is before me from Omai, British Guiana (W. Schaus). Since preparing this description, a female from St. Jean, French Guiana, has been sent to the Museum by Mr. Schaus, labeled ‘‘ C. cupreiplaga Hamps.,” a manuscript name at the time but lately published.* AMOLITA SENTALIS Kaye. 30. Porto Bello, February, 1911 (Busck); Taboga Island, Febru- ary, 1912 (Busck); Corozal, Canal Zone, March and April, 1911 (Busck); La Chorrera, April, 1912 (Busck); Alhajuelo, April, 1911 (Busck); Cabima, May, 1911 (Busck). This is a very small species. The North American A. obliqua Smith is very similar in markings, but of twice the size and I believe a distinct species, not a synonym of sentalis. In obliqua a faint longitudinal band runs below the cell and joins the inner of the two lines. This is only slightly indicated in sentalis. AMOLITA PEPITA, new species.? 5 A medium-sized species, marked as in sentalis Kaye. The inner of the two lines is distinct and broad, black next the apex, partly Ne eee eee ee ae 1 Ann. Mag. Nat.

The single specimen is a female and much rubbed, but I think refer- able to this species. CASANDRIA INTERSTITIA, new species. Similar to leucopis, more shaded with dark red; reniform mark larger; lines similar, mesial line forming a coarser zigzag below; subterminal spots distinct and separated, not shaded together, pre- ceded rather than followed by yee shading. Hind wing with broader fuscous border. Type.—Female, No. 15912, U.S.N.M.; Cabima, May, 1911 (Busck). A male from Guapiles, Costa Rica (W. Schaus), has more white shading, especially preceding the subterminal spots. Hind wing pure white to the margin without terminal line. CASANDRIA ABSEUZALIS Walker. 1. La Chorrera, May, 1912 (Busck).

Smooth dark gray with reddish tint; lines much asin abseuzalis but gray, faint, scarcely legible on the dark ground; subterminal dots sagittate and subconfluent, black, distinct, forming a dentate sub- terminal line; terminal dashes obscure. Hind wing fuscous, veins darker. Expanse, 24-26 mm.

Trinidad River, March, 1912 (Busck). A badly rubbed female, but I think certainly to be this species. CASANDRIA FLOTSAMA, new species. Gray; fore wing stained with reddish, all the marks obliterated, only a large irregular reniform ring in dull red, formed by a segment of the outer line distantly bordering the reniform spot, as this marking is modified in steniptera Schaus; dark streaks at base; a dark gray clouded subterminal shade, rising broadly on inner margin, narrowing above, edged outwardly by a little pale gr ay Hind wing dark ee Expanse, 20 mm. Type-—Female, No. 15918, U.S.N.M.; Trinidad River, March, 1912 (Busck). CASANDRIA SIOPERA, new species. Costa gray in and beyond cell; subterminal line blurred, dentate; the rest of the wing carneous gray, the lines faintly indicated in dark red; reniform round, pale with red center. Hind wing pure white in the male, with broad blackish border in female, running up along the veins. Expanse, 26 mm. Cotypes——Two specimens, No. 15916, selected from a series of twelve; La Chorrera, May, 1912 (Busck); Cordoba, Mexico, May, 1906 (W. Schaus); Orizaba, Mexico (Schaus collection and R. Miller). Sir G. F. Hampson examined one of the Mexican specimens and pronounced it to be his C. hematopis, described from Argentina. It appears to me to differ in the presence of the heavy gray costal shade 202 PROCEEDINGS OF THE NATIONAL 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 (?) lena 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 entirely similar structure and Jscadia aperta Walker has no retinaculum 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 line slender, denticulate, broken into three black points in the cell; outer line denticulate, followed by whitish, starting from costa above the large annular reniform, making a broad half circle to below reniform, then to inner margin; subterminal line blackish, denticulate; terminal dots small, in a purplish shade. Hind wing black on the margin, pale over the disk; frmge whitish. Ex- panse, 18 mm. Type-——Male, No. 15919, U.S.N.M.; Corozal, Canal Zone, June, 1912 (Busck). 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. Hind wing with 4 absent, 3 and 5 from cell. Palpi with the second joint fringed above with hair toward extremity, third jomt moderate, tapered. Fore wing convex at base as in Sarrothripa. Type of the genus.—Egchiretes nomimus, new species. EGCHIRETES NOMIMUS, new species. Dark gray; fore wing with a white patch on inner margin at basal third; subbasal line double, slender, blackish, from costa to sub- median; black dashes on subcostal and a spot on submedian; inner line blackish, waved, filled by whitish; two black discal points in a white spot, followed by a white streak toward apex; outer line black, fine, single, denticulate, gently curved, with an ward dentation at vein 2, followed by white; subterminal line whitish, preceded by fuscous, broken by a white spot below costa; minute terminal black 1Cat.

Hampson’s Catalogue of the Lepidoptera Phalene were not available at the time of writing. Two are before me as proof is read, but to use them would require a complete resetting of the type. In the following the subfamilies and genera will be found mixed, the arrangement being provisional.

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 Guenée, 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 Guenée, from Texas, Mexico to Panama. These three species all occur in 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 scaling on the underside of the hind wings of the male. The larve described by me as latipes t should be referred to disseverans. GONITIS EDETRIX Guenée. 1. Corozal, Canal Zone, July, 1912 (C. P. Crafts). ANOMIS EXACTA Hiibner. 7.

Trinidad River, May, 1911 (Busck). 1 Two other species were confused with aroata in the collection. They may be designated as follows: BETOLA DENSISSIMA, new species. Male antennz bipectinate on basal half. Fore wing with the markings finer and more densely crowded than in aroata, the costa not darkly shaded; pale subcostomedial area not contrasted, without a distinct, pale ray to apex; central ray at vein 5 divided by a double brown streak. Hind wing fuscous tinged, especially on the veins, inner margin, and terminally. Expanse, 43 mm. Cotypes.—Four males, No. 15950, U.S.N.M.; St. Jean, Maroni River, French Guiana, May, 1904 (W. Schaus); Geldersland, Surinam River, Dutch Guiana (W. Schaus); Omai, British Guiana (W. Schaus). BETOLA APOSTATICA, new species. Male antennz subserrate and fasciculate. Fore wing with the markings coarse, broad, and open; central clay-colored area running from base to apex as in aroata, washed with red-brown, not olive as in aroata; no pale ray at apex; ray at vein 5 reduced to a streak with an angled mark above. Hind wing fuscous tinged, especially on inner and outer margins; veias dark. Expanse, 45 mm. Cotypes.—Four males, No. 15951, U.S.N.M.; Rio Potaro, British Guiana (W. J.

Paraiso, Canal Zone, January and February, 1911 (Busck); Porto Bello, April, 1912 (Busck). The Porto Bello specimen is a male, agreeing with the type from Colombia, but small. The two females from Paraiso are darkly suffused, showing only a trace of the mesial light marking; but as the female of tuna was heretofore unknown, this may be the normal marking of that sex. HETEROCAMPA VIRIDESCENS Walker. 1. Cabima, May, 1911 (Busck). HETEROCAMPA LOPODITES, new species. Blackish and brown, a little green tinted especially along costa. Inner line white, angular, showing a sharp zigzag next to inner margin, within which is a basal ocherous ray, edged with black below; discal mark brown with reddish field; outer line geminate, reddish filled, becoming white above inner margin; subterminal spots black. Hind wing with costal edge gray, crossed by a waved pale line; discal area more or less pale; fuscous shaded with linear terminal line. Expanse, 33-37 mm. _ Cotypes. Three males, No. 15952, U.S.N.M.; Paraiso, Canal Zone, Panama, January, 1911 (A. Busck); Tuis, Costa Rica, June, 1907 (W. Schaus); Sixola River, Costa Rica, March, 1907 (W. Schaus). Allied to H. proba Schaus, less green and with distinctive markings on inner margin. Mr. Schaus did not make a positive determination of this species. He evidently recognized it as distinct, but did not wish to describe it. MASCHANE ERRATIPENNIS Walker. 1. Alhajuelo, April, 1911 (Busck). RHUDA FOCULA Cramer. 1. Cabima, May, 1911 (Busck).

Light gray; at base of fore wing a curved black streak staimed with brown from base to inner margin at inner line; inner line double, curved, dentate, cutting off a dark gray-filled blotch on costa; reni- form constricted, with an inner appendage above; outer line double, stained with brown, lunulate, followed by a row of round black blotches, encircled by gray and clouded without the lne from costa subapically and approximate to outer line below; subterminal linear, black, dislocated into segments above and projected on the veins below. . Hind wing whitish at base, dark fuscous without; fringe white. Expanse, 42 mm. Cotypes.—Three females, No. 15953, U.S.N.M.; Taboga Island, Panama, February, 1912 (A. Busck); Sixola River, Costa Rica, August, 1907 (W. Schaus). Closely allied to R. prerupta Dognin from French Guiana, which, however, lacks the basal arc and has the hind wing less whitish at base. The Sixola River specimen is marked “R. 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. 2 ” 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.

VoL. 47, fovea. Straw-color, the margin purplish to outer line, which is dark and irregular; discal dot minute; two shaded marks on costa; all the marks faint and not contrasted. Expanse, 9 mm. Female.—Wings more pointed; markings the same but more dis- tinct, discal dot and broad purple border, reaching almost to the edge, but little vacuolated with straw-color on the margin, limited within by the darker, more purplish line, which is slightly irregular; two faint marks on costa; no marginal dots. Expanse, 10 mm. Cotypes.—Male and female, No. 16061, U.S.N.M.; Taboga Island, June, 1911 (Busck).

PTYCHOPODA UMBRIMARGO, new species. Male with a hair-tuft on the mid tibiz, which are short and have one very long spur and one short one; fore wing simple. Brownish straw-color, irrorate with purple; discal dots black; outer line evenly curved, scarcely at all irregular, the marginal space filled in with purplish except along the apex and tornus, where it is pale; a row of terminal black dashes; fringe pale. Expanse, 11 mm. Cotypes——Male and female, No. 16062, U.S.N.M.; Cabima, May, 1911 (Busck).

Close to P. onca Druce, female, but the outer line is more parallel to the margin, making the marginal purple area more uniform and broader at tornus. Differs from P. subcrinita Schaus, female, in the even outer line. PTYCHOPODA VAGATA Warren. 1. Trinidad River, March, 1912 (Busck). PTYCHOPODA SINCERIO, new species. Male with a hair-tuft at base of middle femur and large one on tibia; a tuft covering the base of the small hind leg. Hind wing small, oval, with but one anal vein close to the margin. Pale straw- color, the margin broadly purplish, limited by the irregular outer line, vacuolated on the termen; a row of terminal dashes. Hind wing with the outer half purplish, a little mottled. Expanse, 11 mm. no. 2050. LEPIDOPTERA OF THE PANAMA CANAL ZONE—DYAR. 237 Type.—Male, No. 16065, U.S.N.M.; La Chorrera, May, 1912 (Busck) Two females, which I have tentatively associated, closely resemble P. cedrica cited above, but are rather darker; Cabima, May, 1911 (Busck) ; Corozal, Canal Zone, July, 1912 (J.

Allied to rufarenaria Warren. GONIACIDALIA BALMATA, new species. Uniformly purplish, evenly irrorated; discal dot large; outer line crenulate. Hind wing notched on the margin, the anal angle lobed and distorted; a groove in the center of the wing above containing orange hairs. Expanse, 12 mm. Type.—Male, No. 16063, U.S.N.M.; Taboga Island, February, 1912 (Buseck). Also four other males, Corozal, Canal Zone, March, 1911 (Buseck); La Chorrera, May, 1912 (Busck). Like G@. furciferata Packard, but smaller and darker. Some of the females cited under P. umbrimargo above may appertain to this species. Accurate association of the sexes is difficult.

Male with yellow hairs along inner area of hind wing below. Expanse, 11-12 mm. Cotypes.—Two males, No. 16067, U.S.N.M.; Trinidad River, March, 1912 (Busck). Near D. caudata Warren, but the hind wing squarer, less pointed at tornus. DEINOPYGIA GOSPERA, new species. Similar to the preceding, the wings more rounded, less acute; hind wing rounded, outer margin scarcely excavate, anal angle not at all tailed; below in the male with yellow hairs along inner margin. Band of fore wing more upright, more bent, indistinctly attaining the costa; terminal dots all along the margin. Lines of hind wing slen- derer, linear, less oblique. The female is similar, but the band on hind wing is broad. Expanse, male, 10 mm.; female, 11 mm. Cotypes.—Male and female, No. 16068, U.S.N.M.; Taboga Island, February, 1912 (Busck), and Porto Bello, April, 1912 (Busck).

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 pale 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.

RGSELIA HYPOPECTA, new species. Whitish gray; a square black blotch on the middle of costa reach- ing down to median vein; a wavy median line just beyond it and close to the outer line, which is slender, straight, running obliquely between veins 6 to 2; subterminal line wavy, shaded, blackish, fol- lowed by brown except at apex, the brown ending in dark terminal points. Hind wing pale fuscous. Expanse, 13 mm. Type.—Female, No. 16078, U.S.N.M.; La Chorrera, May, 1912 (Busck). RESELIA MICROPECTA, new species.

Whitish, rather coarsely irrorate with blackish; a dark spot on base of costa; inner line shaded, curved; outer line oblique to costa, bordering a dark oblique patch, then curved around parallel to mar- gin; subterminal line regular and even, parallel to margin, finely den- ticulate; the gray irrorations denser on the margin. Hind wing pale, fuscous tinged along veins and margin. Expanse, 15 mm. Type.—Male, No. 16081, U.S.N.M.; Cabima, May, 1911 (Busck). NOLA ZXSCHYNTELA, new species. Pale gray with black irrorations in clusters; inner line slender, curved, irregular; outer line dotted, excurved over cell and less so below, preceded by a black shade throughout, but most distinct below with red-brown shading on margin and tornus; subterminal line spot- ted and diffused, blackish; margin darkly irrorate. Hind wing fus- cous, pale at base; discal dot darker. Expanse, 14 mm. Cotypes.—Two females, No. 16083, U.S.N.M.; Trinidad River, March and June, 1912 (Busck). Also one male and six females with additional localities, La Chorrera, May, 1912 (Busck); Paraiso, Canal Zone, January, 1911 (Busck). NOLA BRUNNEIFERA, new species. 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, forming streaks on the veins; brown marking on inner mar- gin to tornus distinct; terminal markings reduced to irrorations. Hind wing pale, with more fuscous margin. Expanse, 12 mm. Cotypes.—Two males, No. 16084, U.S.N.M.; La Chorrera, May, 1912 (Busck). Possibly this is the male of xschyntela, of which the single male cited as paratype is badly rubbed. NOLA NEPHELEPASA, new species. Pale gray, the markings 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. Hind wing gray, pale at base; no trace of discal dot. Expanse, 15 mm. Type.—Female, No. 16085, U.S.N.M.; Corozal, Canal Zone, April, 1911 (Busck). NOLA CHAUNA, new species. Whitish, broadly gray on the margin, cut by the whitish sinuate subterminal line and narrowly separated below from the slender, powdery, blackish outer line, which forms two smooth arcs; costa shaded with brown, broadening out beyond base and forming a larger patch beyond middle; a few dots toward apex. Hind wing fuscous no. 2050. LEPIDOPTERA OF THE PANAMA CANAL ZONE—DYAR. DA tinged, most strongly so outwardly, the veins darker. Veins 7-10 stalked, 9 absent, 11 straight. Expanse, 9 mm. Cotypes.—Three males, No. 16086, U.S.N.M.; Cabima, May, 1911 (Busck); Alhajuelo, April, 1911 (Busck). 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 into a small patch at the end. Hind wing translucent fuscous. Expanse, 12 mm. Type.—Female, No. 16093, U.S.N.M.; Cabima, May, 1911 (Busck). More like artata in costal marking than chawna is, but the outer line does not form a prominent coarse tooth on submedian as in artata. I have also placed here two females in poor condition from La Chorrera, May, 1912 (Busck), and Trinidad River, March, 1912 (Buseck). : NOLA PROTHYMA, new species. Whitish, the margin gray and with a roundedly irregular, clouded submarginal line; a spot at base of costa; inner line coarse and den- tate, obsolete below; a triangular costal, median, brown mark, from which a straight line runs across the wing; outer line slender, pow- dery, and a little broken, forming an arc above and a small one below.

NOLA QUINTESSA, new species. Pale gray, irrorate, the irrorations a little denser at the margin; subterminal shade rather remote, clouded, undulate on its outer mar- gin; outer line nearly straight, oblique, shaded, and powdery, outbent a little in the middle; inner line broad, shaded, subparallel to the outer and likewise oblique. Hind wing pale gray; no discal dot. Expanse, 13 mm. Type.—Female, No. 16091, U.S.N.M.; Corozal, Canal Zone, March, 1911 (Busck). Allied to N. apera Druce, but the outer line not forming points on the veins. NOLA ZETECI, new species. Blackish gray, dark, the fore wing narrow, its margins subparallel; a dark blotch at base and a large one near middle of costa, clouded and diffused across the wing; outer line oblique, dotted on the veins; subterminal somewhat dotted, obscure; a row of terminal black dots. Hind wing pale with fuscous margin and discal dot. Ex- panse, 14 mm. 248 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. Type.—Male, No. 16090, U.S.N.M.; Corozal, Canal Zone, July, 1912 (J. Zetek).

Fore wing washed with pale yellow from base to outer line, with black irrorations and a central shade in place of inner line; costa pale brownish with two inconspicuous expansions; outer line black- ish, distinct, smooth, evenly excurved above; terminal area pale gray, clouded with darker gray next the outer line and termen; sub- terminal line sinuate, denticulate, narrow, dark. Hind wing fuscous, paler at base; no discal dot. Expanse, 16 mm. Type—Female, No. 16095, U.S.N.M.; Trinidad River, March, 1912 (Busck). NOLA HABROPHYES, new species. Head and thorax pure white. Base of fore wing white, with dark brown basal costal spot; terminal two-thirds of wing black-brown, bounded by an upright, straight edge; black area with scattered dark and silvery blue scales; a faint pale, smooth outer line visible, excurved over cell; some pale scales before the apex. Hind wing blackish gray; discal dot darker. Expanse, 13 mm. Type.—Female, No. 16082, U.S.N.M.; Trinidad River, March, 1912 (Busck). CELAMA SORGHIELLA Riley. 10. Corozal, Canal Zone, July, 1912 (J.

Hind wing pale grayish, darker on the margin: no discal dot. Expanse, 11-13 mm. xo. 2050. LEPIDOPTERA OF THE PANAMA CANAL ZONE—DYAR. 249 Cotypes.—Male and female, No. 16096, U.S.N.M.; Trinidad River, March, 1912 (Busck). Also 14 others with additional localities Cabima, May, 1911 (Busck); La Chorrera, May, 1912 (Busck); Ta- boga Island, February, 1912 (Busck). Three out of the sixteen specimens retain vein 8 in the fore wing and would therefore be referable to Nola, if this were not evidently a case of variation. Family COCHLIDIID.

The specimens agree with a female from Costa Rica labeled by Mr. Schaus. In the male, there is a slight swelling on the costa between end of first line and discal dot. SYNGAMIA SCIAGRAPHALIS, new species. Differs from abnormalis (Snellen) Schaus in being tinged with ocher, especially along inner margin, the costa of the male straight, without swelling; lines of hind wing not quite as coarse and rigid as in abnormalis, the whitish bordering shades less contrasting.

Similar to L. meliusalis, with which it was confused in the collection, but with the blackish scales almost wholly removed. In meliusalis there are indistinct dark edgings to the stigmata and a dark terminal line, which breaks into three distant dots below apex, derived from the coropetype. 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.

A smaller species with straight costa in the male, resembling S. cognatalis (identified by Schaus); more uniformly straw-yellow, with- out the general dark shading of cognatalis, the lines of hind wing not so flexuous and irregular, though much less rigid than in abnormalis or sciagraphalis, but easily distinguished from all by a patch of long black seales at base of costa of hind wing of male on both surfaces of the wing.

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 jomt 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 jomt of male antenna, the other without this structure. I name herewith all of the Panama forms, as I do not think that any of them are Guenée’s apygalis, described from Colombia from a single female with the costal dots opened into rings. My nacobora is the only one showing this marking, and it does not appear to agree otherwise with apygalis. No. 1. HOHAELIS, new species. Small, nearly white, the male without modification at base of antenna; costal dots of fore wing confused, at base reaching to sub- costal vein; lines slender; ground color not much shaded with dark; space between outer and subterminal lines moderately wide, narrowly reaching costa but cut off from inner margin; discal dots of both wings with the centers nearly occluded.

SPARSALIS, new species. Medium sized, faintly straw-yellow tinged; costal dots of fore wing small and sparse, on costa only, separated by twice their own diam- eters or more; lines moderate; ground color shaded with dark along the margins of both wings; space between outer and subterminal lines moderately wide, narrowly reaching costa and indistinctly so the inner margin; discal dot of fore wing of two lines joined by a bar, of hind wing solid. Expanse, 12 mm. Type.—Female, No. 16130, U.S.N.M.; Trinidad River, March, 1912 (Busck). No. 3. APPROPRIALIS, new species. Medium sized, pale straw yellow; costal dots of fore wing numerous and rather dense, those near base reaching subcostal vein; lines moderate, distinct; ground color strongly shaded with brown along the margins of both wings, not elsewhere; space between outer and subterminal lines moderately wide, narrowly reaching the costa and. indistinctly so the inner margin; discal dot of fore wing closed above and crossed by a central bar, of hind wing small, solid, forming part of the mesial line. Expanse, 13-14 mm. Cotypes.—Two females, No. 16131, U.S.N.M.; Trinidad River, March, 1912 (Busck). I associate with these the unidentified male from Costa Rica (Banana River, March, 1907, W. Schaus) without modification at the base of the antenne. No. 4. DIFFERENTIALIS, new species. Medium sized; pale straw yellow; costal dots small, but rather numerous and dense; lines very fine and open, the marginal shade slight, giving a general pale, unshaded appearance; space between outer and subterminal lines wide, reaching costa and margin; orbicular annular, semidetached from the inner line; discal dot closed above and with central bar, of hind wing not quite occluded and detached from the inner line. Expanse, 13-14 mm. Cotypes.—Four females, No. 16132, U.S.N.M.; Corozal, Canal Zone, July, 1912 (J. Zetek, C. P. Crafts), November, 1912 (C. P. Crafts). No. 5. DENSALIS, new species. Small, pale straw yellow, shaded with ocher-brown beyond the discal mark; costal dots dense, regular, reaching subcosta, where there is a longitudinal shade; ground color slightly irrorated and with patches of dark brown shading at origins of discal venules of both wings, the marginal shading broken up into patches; space between outer and subterminal lines moderately wide, reaching costa; discal dot of fore wing lunate, annular, of hind wing solid.

Rather larger than the others and with broader, squarer wings; white, tinged with sordid creamy; costal dots small, sparse, the basal three distinctly annular; lines slender, blackish, the inner running within the orbicular instead of joming it above; reniform widely annular; marginal shade represented by a few dots only, the sub- terminal line faint and running close to the outer line above. Hind wing with discal dot narrowly annular; a dusky shade between the inner and outer lines; termen as on fore wing. Expanse, 14 mm. Type.—Female, No. 16134, U.S.N.M.; Trinidad River, June, 1912 (Busck). BOCCHORIS EDAPHODREPTA, new species. Rather small, the wings narrow and acute at apex; antenne of male without basal modification; white with irrorations and shades of pale creamy brown; thorax and base of fore wing heavily and densely dotted with black; lines slender, dark, the inner straight, upright, outer oblique, running in along vein 2 to a sinus, then to inner margin; discal mark solid; a faint subterminal brownish shade; two black dots on the costa subapically. Hind wing with solid discal dot, with black shade thence to inner margin; two outer lines joining near costa, roundedly and widely separated mesially, then close and parallel on inner third; a brown subterminal shade, espe- cially toward apex. Expanse, 11.5 mm. Type.—Male, No. 16135, U.S.N.M.; Porto Bello, May, 1911 (Busck). BOCCHORIS INVIDIOSA, new species. A larger species than the preceding, the wings rather narrow and square at tip; whitish, lightly tinted with straw color, the brown marginal shade dark and continuous on fore wing, paler and scattered on hind wing; lines slender, the outer finely denticulate, both on its outcurve below costa and before the retreat along vein 2; similar on hind wing, straight only from vein 2 to tornus; costal dots small, annular, well spaced, less than twice their own diameters apart; reniform open above and below, without cross-bar; on hind wing widely annular with a slightly curved line running to above tornus. Expanse, 18 mm. Type.—Female, No. 16136, U.S.N.M.; Trinidad River, May, 1911 (Buseck). Nearest to Guenée’s characterization of apygalis of any before me. The specimens in the collection allied to this (one species of two females from French Guiana, one species of three males and four females from Aroa, Venezuela) were all placed under Hileithia decostalis Guenée, on general appearance, evidently, as they differ in venation, while none bear identification labels. There are evi- dently a considerable number of allied species in this group, and apygalis can only be positively identified from Colombian material. 268 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47. BOCCHORIS RHEHABALIS, new species. Closely allied to B. rhealis Druce; smaller, whiter, the subterminal line on both wings straighter, not forming two arcs as in that species; the inner line of fore wing 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 (Busck). I have placed rhealis and magnalis Guenée in Bocchoris instead of Nacoleia as done by Hampson, because I think the front of the head might as properly be described “flat and oblique” as ‘‘rounded,” it being of an ambiguous shape, and by so doing I associate these species with the others which 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 “ *Pachyzancla xgrotalis Zell. @ ” by Sir G. F. Hampson, but the palpi donot seem to me to agree with those of Pachyzancla. The specimen examined by Sir George has the palpi broken, but anyway the specimen is very much too large for the female of exgrotalis, of which I have many of the same size as males. The present species is near S. silicalis Guenée, 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 THIALIS, new species. A little larger and broader-winged than novalis, the male antenne with a thickening bearing short hairs near the middle, the anal tuft very small and brush-like, inconspicuous; outer margin of fore wing quite straight, with a small notch at end of submedian fold. Color as in novalisand equally without markings, the darker patch at anal angle of hind wing somewhat larger and a little less contrasted. Expanse, 32 mm. Type.—Male, No. 16147, U.S.N.M.; Corozal, Canal Zone, March, 1911 (Busck). PILETOSOMA ARGOPONALIS, new species. Wings broad, the outer margin rounded below, without notch; male antenne minutely ciliate, unmodified; anal tuft large and rather long, but nothing like the enormous development of this structure in novalis. Brown-black with slight bronzy reflection; no. 2050. LEPIDOPTERA OF THE PANAMA CANAL ZONE—DYAR. oS lines showing only in traces; reniform small, annular; inner and outer lines faintly pale, the outer looped under reniform, thence oblique and irregular to inner margin.

As determined by Mr. Schaus from Costa Rican specimens ((atilim- balis Guenée=contactalis Dognin), but not the latilimbalis of his Guiana collections, nor the contactalis labeled by Mr. Dognin. In the present form, the spot on fore wing is very much larger (latilim- balis 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. LYGROPIA GLAPHYRA, new species. Bronzy brown-black; fore wing with a small yellow costal spot at outer third; a narrow band at basal third, not attaining costa, bent below cell at right angles toward base and joining some diffused yellow on inner margin.

It approaches modialis Dyar, but the broadening of the bands is not so great, while the size is not increased. GLYPHODES BUSCKI, new species.

The male has the costa yellow (=Sameodes flavibaccata Hampson *) ; in the female it is black and the markings are broader (= Pyrausta dilecticolor? Dyar). Under the name flavibaccata, Mr. Schaus sent three distinct species from his Costa Rican collections. The bright yellow one I take to be the real flavibaccata and the name falls before the earlier dilecticolor. The reference to Sameodes instead of Pyrausta seems preferable. The two other species agree with specimens in 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 of flavibaccata. SAMEODES ACTEALIS Walker. 5.

Type.—No. 16174, U.S.N.M., selected from a series of eleven spec- imens; Taboga Island, February, 1912, and June, 1911 (Busck); La Chorrera, May, 1912 (Busck); Aroa, Venezuela (Schaus collection). A larger race of this species from Costa Rica has been identified as gelliasalis by Mr. Schaus, but the markings of hind wing and the color agree with declivalis. A form of this species occurs in the West Indies, for which I propose the name indianalis, in which the mark- ings are very faint, hardly legible on either wing. The hind wings have a whitish tint toward base. Expanse, 13 mm. Type.—No. 16175, U.S.N.M., selected from 20 specimens, Santiago de Cuba, Cuba, June, 1902 (W. Schaus); Jamaica (Schaus collection) ; Culebra Island, Porto Rico, February, 1899 (A. Busck); Grenada, British West Indies (Schaus collection). STENIA ACUMINALIS, new species. A rather large form, brownish black shaded, with a slight ocherous tint, which comes out strongly on the costa in rubbed specimens; lines whitish, black edged, essentially as in gelliasalis. Hind wing black, whitish only on the costa, the lines as in declivalis, but softened and somewhat less contrasted. Expanse, 14 mm.

Cotypes—Male and female, No. 16275, U.S.N.M.; male, Porto Béllo, April, 1912 (Busck), female, Cabima, May, 1911 (Busck).

The males vary in color from light red to a dark purple like the females. Range in size for males, 8-10 mm.; for females, 8-10 mm. The females are constant in coloration. I possess specimens like these (except that veins 4—5 of fore wing are stalked) from Trinidad and French Guiana labeled ‘“ Lepidomys fuscalis Hampson, cotype ¢” [recte 92], from Venezuela labeled “ Lepidomys cuprealis Hampson, cotype ¢, type @,” and one from Mexico with the same label (fuscalis, cotype male). In this latter, veins 4 and 5 of the fore wing are from the cell, as in the Panama specimens. Lepidomys Guenée! was described as a Noctuid and its single species, L. irrenosa Guenée was credited to New York. The name stood in our old lists, but I omitted it from Bulletin 52, United States National Museum, as the late Prof. J: B. Smith stated that it was not North American. Hampson did not include it in his papers on the Pyralinz (1895-8), evidently having discovered that it was a Pyralid only subsequently to that date.2 As the species L. trrenosa is unknown to me, I use the new name Restidia, which can be made a synonym if no differences appear. The names fuscalis and cuprealis of Hampson apply to the forms with veins 4—5 of fore wing stalked, to light and dark males on one species, in my opinion. I have also specimens identified by Mr. Schaus as Lepidomys lineosa Druce (Azamora lineosa Druce*), one from Mexico, one from Costa Rica. They are not conspecific, and neither, perhaps, the true lineosa from Ecuador, but they appear from Guenée’s description to be simi- 1 Spec. Gen., vol. 6, 1852, p. 201. 2 Ann. Mag. Nat. Hist.

If really related, and irrenosa proves structurally similar, they may be easily separated generically by the absence of vein 10 in fore wing, so that the genus Restidia will be justified.

Specimens from the Guianas have been labeled by Mr. Schaus “Cataclysta perlalis Led.; trilinealis Walk.” But I have been unable to trace these names. The species can not be a Cataclysta on account of the absence of the tongue. MACROTHECA PECILOSTIGMA, new species.

The Costa Rican series runs strongly marked. The Panama one runs about like a series from Venezuela before me, that is rather con- trastingly marked, more so than the Guiana series.

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.

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 ciniliza. 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.

The Guatemala sp. on which Discopalpia is founded is quite distinct.”” Discopalpia Ragonot' was supposed to have been founded on Myelois flavicans Zeller, but according to the above note, Ragonot’s specimen was misidentified. /lavicans falls in Presmopoda, and Discopalpia, with this type, therefore becomes a synonym of Piesmopoda, its diagnosis being in error, taken from a different, unnamed species.

THE VARIATIONS EXHIBITED BY THAMNOPHIS ORDI- NOIDES (BAIRD AND GIRARD), A GARTER-SNAKE IN- HABITING THE SAUSALITO PENINSULA, CALIFORNIA. By Josrera 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).! This species presents a remarkably large series of variations, is equaled by no other in the genus, and is only approached by 7. ele- gans and T. radix which occupy regions five to eight times greater in extent. The specimens upon which this study is based were captured on the Sausalito 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 this 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 rowsisresumed. The 19 rows continue to the level of the eighty-fifth gastrostege, when the 1 Bull. 61, U. S. National Museum, 1908, p. 147. PROCEEDINGS U. S. NATIONAL MUSEUM, VOL. 47—No. 2051. 351 oon PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47. IV 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. One of the variations in the scale formule 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, ITI, IV (V suppressed constructively), VI, VII, VIII, IX, and the median row. Another variation is where the count is 19-17-15. In this 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 usually one or two pairs of small gular shields; these are followed by from one to three shields in the median line 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 THAMNOPHIS ORDINOIDES—THOMPSON. 3855 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 single 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 Thamnophis, in 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 Dipsadomorphine 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 intermediate 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 begins 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 formule the specimens vary in eight additional dermal characters. The shields 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. 8. Nat. Mus., p. 17, 856 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 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.

The normal condition is three shields.

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 type the third and fourth enter the eye.

If compared with the two previous tables for the normal scale formula several points of interest may be elicited. 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 formule. Where the count is 19-17, the [V rowis usually suppressed, exactly as in those with the normal formula, a little behind the gall bladder. As to the length of the spinal column, it is clear that whatever increase or decrease in the number of dorsal vertebre that takes place in an individual specimen is brought about by the addition or sub- traction of vertebre in that part of the column that is between the posterior end of the left kidney and the base of the tail. HABITAT. The Sausalito 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 Ariolimaz. 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 PEARLY FRESHWATER MUSSEL OF THE GENUS HYRIA FROM BRAZIL. By L. S. FRrIEeRson, Of Frierson, Louisiana. While 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 “ Hyria 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 brownianus 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 contiecting link between the genera Hyria and Diplodon. (It is not impossible that this species may be the “ Hyria humilis 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, solid, 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. Nacre white and purplish (somewhat dis- eased in the center of the type-specimen). Type.—Cat. No. 83877, U.S.N.M. Proceepinas U. S.

Type of the genus.—Gorgora morga, new species. 378 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47, GORGORA MORGA, new species. Black; thorax dorsally, palpi and hairs on femora orange. Fore wing shining greenish black, the marks edged with dull black; a large round orange discal spot; a marginal orange band, dentate out- wardly, touching termen by its dentations on the veins, the fringe black. Hind wing black, with only a little metallic gloss. Expanse, 34 mm. Type.—Female, No. 15463, U.S.N.M.; Mexico City, Mexico, Sep- tember, 1912 (R. Miiller). Genus TROGOBLEMMA Hampson. TROGOBLEMMA CACODOXICA, new species. Fore wing with the outer margin excavate in its upper half, leaving a projection at middle; red-brown, irrorate with purplish and a little red; markings illy defined. A small black discal dot. Hind wing light fuscous. Expanse, 15-20 mm. Cotypes—Three females, No. 15464, U.S.N.M.; Orizaba, Mexico (Schaus collection); Juan Vinas, Costa Rica, November, 1909 (W. Schaus). Very close to 7. 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 cacodoxica, the hind wings of the female are entirely fuscous shaded, the band beneath shaded, obscure and only slightly 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 7. acutalis Schaus the tongue is absent, but it has been broken off, and is plainly visible in other specimens before me from the same locality. 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 7. modesta.

Resembles Zophodia dryopella Schaus very closely in markings. One specimen is labeled ‘‘ Vitula edmandsit Pack.” in Sir G. F. Hampson’s writing and on another is the same name in Mr. Schaus’s hand; but this determination is extremely wild and must be due to some mistake. Genus ANCYLOSTOMIA Ragonot.

By Joun B. HENDERSON and Paut Bartscu, Of 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 fauna. 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. Our chief desire was to find out of just what ele- ments the molluscan 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 our somewhat haphazard choice of a locality for we encountered at Chincoteague a greater variety of stations than likely can be found at any other one point along this section of the coast. There are, first, 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, with 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 Cardiwm 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 drops off very gradually to me edge of the con- tinental shelf, some 75 or 100 miles out. The open-sea stations we occupied were, as ey 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 soundings indicated some more promising areas of pebbly bottom a few miles beyond what we considered the safety zone for a small motor boat. The inner waters of the sound we found unexpectedly 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 Verrill. PECTEN GIBBUS IRRADIANS Lamarck. MYTILUS EDULIS Linnaeus. SCAPHARCA TRANSVERSA Say.

It seems useless to attempt any divisions into sub- species based upon color characters only. EUPLEURA CAUDATA Syy. 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 known to collectors (20.8 mm. long by 11.4 mm). EPITONIUM VIRGINICUM, new species. Plate ds iond: 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, Virginia. It has a trifle more than three post-nuclear whorls, and measures: Length, 3 mm.; diameter, 14 mm. This little gem appears to be a full-grown individual, judging by the slight thickening of the lip.

TURBONILLA (PYRGISCUS) POCAHONTASAE, new species. Plate 14, fig. 4. Shell broadly conic, bluish white. Nuclear whorls 24, forming a depressed helicoid 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 protractive, 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.

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 14 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 first 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.

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 xo.2055. MARINE MOLLUSKS—HENDERSON AND BARTSCH. AT i 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. Periphery of the last whorl well rounded. Base moderately long, well rounded, marked by the continuations of the axial ribs, which disappear shortly after passing the periphery, and 15 incised spiral lines of somewhat varying width.

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 first 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. Suturechanneled.

The two specimens of this species, Cat. No. 252578, U.S.N.M., were dredged at Chincoteague Bay, Virginia. One of these, the type, has 5 postnuclear whorls, and measure: Length, 2.2 mm.; diameter, 1 mm. ODOSTOMIA (CHRYSALLIDA), species? A specimen which we are unable to refer to any of the known forms, but which is too poor to serve as type for a new species. ODOSTOMIA (MENESTHO) IMPRESSA Syy. Two specimens. ODOSTOMIA (EVALEA) VIRGINICA, new species. Plate 13, fig. 3. Shell small, elongate-conic, bluish white, with a narrow pale yellow band a little anterior to the summit. Nuclear whorls decidedly obliquely immersed in the first of the succeeding turns, above which the tilted edge of the last volution only projects. Post-nuclear whorls moderately well rounded, weakly shouldered at the summit, marked by decidedly retractive lines of growth and exceedingly fine spiral striations. A slender spiral thread 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 thin callus. The type and 4 specimens were dredged at Chincoteague, Virginia. The type, Cat. No. 252576, U.S.N.M., has 6 post-nuclear whorls and measures: Length, 2.7 mm.; diameter, 1.2 mm.

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. The type, Cat. No. 252571, U.S.N.M., was. dredged at Chinco- teague. It has 7 post-nuclear whorls, and measures: Length, 2.7 mm.; diameter, 0.9 mm. TRIPHORIS NIGROCINCTA C. B. Adams. DIASTOMA VIRGINICA, new species. Plate 14, fig. 3. Shell elongate-conic. The early whorls are chestnut brown, the succeeding turns flesh colored, mottled and variegated with brown; in some specimens the chestnut brown extends over the entire shell. 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. Vou. 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 splits, 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, which 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 present 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, 3mm.; and 2.2 mm. at the antepenultimate whorl. There are several species of Diastoma 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 synonymy 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. no. 2055.

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, which 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 first 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 ribs 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.

Dyar, Custodian of Lepidoptera, United States National Museum. 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 already 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.

Ho uisrer, Assistant Curator, Division of Mammals, United States National Museum. INTRODUCTION. The nomenclatorial history of the Grasshopper Mice, or Scorpion Mice, begins with 1841, when Maximilian, 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 (Onychomys) leucogaster (Maximilian) and Hesperomys (Onychomys) torridus Coues. The only definite synopsis of the group since that date was published 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,’ published 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 afford, 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.

VOL. 47. 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, from certain 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. One of the results of the reduction in the number of distinct species to two, and the increase in the number of geographical races of each of these, is the increased difficulty in finding hard and fast, easily defined, conspicuous characters to diagnose these two species. While the two groups of subspecies as two specific units occupy an immense range, one to the north and one to the south, the actual area of overlapping is small.2_ At these points of overlapping, where intergradation could, but does not, take place, the two species are well differentiated externally, there is never the least doubt concerning the species to which a specimen belongs, and a working key to the species in this overlapping area could be made on a great number of simple differences, both external and cranial. Since all the numerous and widely diversified forms have been found to intergrade indirectly with either leucogaster or torridus, however, all of the superficial characters which hold good to identify the species at the few over- lapping points fail with some far removed form, which, although intergrading indirectly with only one of the early named species, may really resemble in any one or any combination of such char- acters some race of the other species with which it has no real con- specific relationship. The teeth present the best characters by 1 The material examined is from collections as follows: United States National Museum, Biological Survey collection...................-..- 1,041 United States National Museum proper’. ...ssehcce-seeece seca sseceee eee esee eee 163 American Museum of Natural History, New York...-............--.--.------------= 118 Museum of Vertebrate Zoology, University of California......................-....- 83 HieldbMuseumjot Natural History, Chicagos....4..2se5 sec ccnence nce ee ee eee 70 Museum of Comparative Zoology, Cambridge. -....---- 2.2225. cee ene c eee seco eee 35 Academy, of Natural Sciences; Philadelphia s:-: 222222252.) see ee ss eee eee 31 Universityof- Nebraska, Lincoln: < 26.25 soem see ae oe ee 15 Kansas University Museum of Natural History, Lawrence..-.................-.---- 5 Biological’ Survey of South, Dakotaiiie< - 2242 22-0. once see ree ee ee eee 1 Total numberof specimens:3-< a5... has -c ance ee aances eee eee Oe eee eee ee 1, 562 2 Tn only four cases do forms of the two species overlap in distribution, for comparatively limited areas in each case, as follows: O. 1. brevicaudus and O. t. longicaudus in western Nevada and Mono County, California. 0.1. ruidosz and O. t. torridus in southwestern Arizona, northern Sonora, southern New Mexico, northern Chihuahua, and extreme western Texas.

The subspecies of each group are closely related and intergradation is in almost every case shown by the material examined. The races are, in the main, well marked over a considerable territory and usually exhibit some conspicuous deviation in color accompanied by varia- tions in dimensions or relative cranial characteristics. The marked diversity in color of skins of Onychomys from almost any locality has given rise to a general impression that true dichro- matism is, in a measure, responsible for the wide differences exhibited. That such is not the case has been one of the general results of the present study. Cases of supposed dichromatism represent various stages in a definite sequence of pelages, shown by a comparison of animals of various ages as determined by the relative wear of the teeth. In torrdus and its subspecies this sequence of pelages is especially complex and, in both groups, abrasion and fading, combined with a gradual moult and renewal, has made the study of the pelages an interesting problem. In an account of the various subspecies it is necessary in nearly every case to describe fully the color of several stages of pelage, so widely do individuals of the same form differ with age and season. MEASUREMENTS. In the tables of measurements appended only the dimensions of fully adult animals have been considered. Measurements of selected specimens showing considerable tooth wear and from as many localities as possible have been used. The total length, tail, and foot measurements are from collector’s notes, made from fresh speci- mens. The length of ear has been taken from the dry skin. The cranial and dental measurements were made with sliding calipers registering tenths of a millimeter. Condylobasal length was taken from condylion to alveolar point, not to most anterior point of the premaxille. ACKNOWLEDGMENTS. An intelligent revision of the grasshopper mice would not have been possible without assembling the collections from various museums for study. Thanks are due the custodians of several mammal collections for the loan of material, which has, in several cases, included types and type series. To Dr. J. A. Allen, of the American Museum of Natural History, New York; to Mr. Joseph Grinnell, Museum of Vertebrate Zoology, University of California; to Mr. Charles B. Cory and Mr. W. H. Osgood, Field Museum of Natural History, Chicago; to Mr. Samuel Henshaw and Mr. Outram 4380 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. Bangs, Museum of Comparative Zoology at Harvard; and to Dr. Witmer Stone, Philadelphia Academy of Sciences, I am indebted for the loan of valuable material, all of which was assembled by the Biological Survey, through the courtesy of Mr. E. W. Nelson. In the lists of specimens examined I have indicated the source of all material from locaJities not represented in the United States National Museum collections. Mr. Vernon Bailey, of the Biological Survey, has given me much information regarding physiographical conditions in localities from which the small number of specimens examined hardly warranted the mapping of boundaries of forms, without inti- mate knowledge of the country.

(See fis 12) Remarks.—Onychomys differs from Peromyscus, its nearest generic relative, in its more hypsodont molars, and in the position and shape of the front cusp of m', which is distinctly in the outer row of cusps, more coniform, less broadened transversly, and with the unworn as | wh. \ or ANE ES Fig. 1.

Although it exter- nally resembles Cricetulus much more than it does Peromyscus, it is as shown by a study of the teeth, separated from the old-world genus by both Peromyscus and Baiomys. The latter, with its close approach to the six-tuberculate pattern in m', appears, of the three groups, the nearest to Cricetulus. Osgood! has pointed out certain peculiari- ties of resemblance between the subgenus Podomys, of Peromyscus, and Onychomys; and has suggested the possibility that Podomys is an intermediate form between Onychomys and typical Peromyscus. The reduction in the number of plantar tubercles in Podomys is prob- ably of no importance in this connection, but the higher-crowned teeth and the relative position of the anterior cusp of the first molar 1 North Amer. Fauna, No. 28, p. 227. Apr. 17, 1909. 432 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. are characters that make the closer relationship seem very probable. Though distinctly belonging with Peromyscus, Podomys is the nearest approach within that genus to Onychomys. List OF SPECIES AND SUBSPECIES WITH TyYPE-LOCALITIES. Onychomys leucogaster.

By A. N. CaupDEL1, Custodian of Orthoptera, United States National Museum. The Orthoptera collected by the Yale expedition to Dominica in 1913 comprises 57 specimens, representing 20 species. Two, a Phas- mid and a Locustid, apparently new, are herein described. No more definite locality is given than that expressed by the following label, which is uniform for each specimen: ‘‘Dominica. June—July, H. W. Foote, Yale Exp. 1913.” By previous agreement types, uniques, and one-half of the remain- ing specimens are deposited in the United States National Museum. Family BLATTIDAE. PLECTOPTERA POEYI Saussure. One female. This specimen is somewhat larger than ones in the United States National Museum from the Greater Antilles and the United States, the elytra measuring 6 mm. in length. Synonymy very surely exists among the species of this genus and a revision is desirable. : PANCHLORA HYALINA Stoll. Four females. EPILAMPRA CRIBROSA Burmeister. One female. This unique specimen seems to fit the description of cribrosa better than that of any other described form which might be expected to occur in Dominica. PYCNOSCELIS SURINAMENSIS Linnaeus. Two immature specimens. In addition to the above roaches there is in the collection a very young nymph of a Blattid which I am unable to determine. Family PHASMIDAE. PARAPRISOPUS ANTILLARUM, new species. One female. Head densly covered with blunt tubercles, a broad transverse furrow between the eyes with a deep longitudinal sulcus above it and a couple of obscure slightly oblique longitudinal furrows, PROCEEDINGS U.S. NATIONAL Museum, VoL. 47—No. 2058. 491 4992 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47. one on each side of the deep median sulcus; occiput with a pair of tubercles very slightly larger than the others, one on each side of the median sulcus. Antenne heavy and basally flattened, especially the basal segment, which is barely longer than broad. Pronotum quad- rate and covered with large tubercles, four, situated two on each side of the median line on the anterior half, somewhat larger than the others; just anterior of the middle of the pronotum is a deep trans- verse furrow and near the anterior border is a second shorter one. There is a pair of shallow posteriorly divergent furrows on the posterior part of the pronotal disk. Mesothorax about twice as long as the anterior width, the width noticably and gradually increasing from the front backwards; surface of mesonotum covered with large rounded tubercles, less elevated than those of the pronotum. Metanotum transverse, the surface covered with tubercles similar to those on the mesonotum. Median segment about twice as long as the metanotum and, like it, covered with bluntly rounded tubercles. Abdomen also covered with rounded tubercles, the segments very slightly longer than broad, the fourth, fifth, and sixth ones more distinctly so; oper- culum falling short of the end of the abdomen, barely exceeding the apex of the eighth segment, apically terminated by a short, blunt pro- jection; cerci short and heavy. Kiytra present as small apically rounded lobes, broader than long and not reaching the posterior margin of the metanotum; wings immovable, fossil-like plates, their apical margin broadly rounded and coincident with that of the posterior margin of the metanotum. Legs short, broad and heavy, all the femora broadly flattened and the margins, especially the lower margins of the middle and hind ones, undulately toothed or tuberculate; fore femora with the basal curve terminating two-thirds the distance from the base; middle femora but twice as long as broad, the hind ones about four times as long as broad. Tibize somewhat flattened and more or less distinctly undu- late above. Tarsi heavy, and as long as the tibie, the anterior ones a little longer. All the legs are covered with tubercles similar to, but smaller than, those that cover the rest of the insect. General color brownish with the tubercles mostly ash-colored, especially those on the head and pronotum; eyes dark brown; there is some black on the occiput and on the front part of the pronotum; some of the segments of the antenne are darkened basally, giving it a ringed appearance; the tibie are variegated with blackish and the hind and middle femora are black on the inner face. Measurements: Length, entire insect, 63 mm.; pronotum, 4; meso- notum, 8; metanotum, 2; fore femora, 7; middle femora, 5; hind femora, 8; width, head, 5; middle femora, 2.5. Type.—Cat.

The above series of this common species exhibits much variation but no extremes not paralleled by specimens in a series of some 300 or more in the United States National Museum collectionfrom Paraguay, named by Professor Bruner. Family LOCUSTIDAE. MICROCENTRUM DIVISUM Walker. Two males. This species will very surely prove synonymous with some one of the later described species of Brunner. NEOCONOCEPHALUS GUTTATUS Walker. One female. The Conocephalus exaltatus of Walker seems very near this species and may indeed be the same. CONOCEPHALUS PROPINQUUM Redtenbacher. One adult male and a female nymph. LEUROPHYLLUM LURIDUM Brunner. Two males. These specimens are a little larger than the measure- ments given in the original description. LICHENOCHRUS FULVICOSTA, new species. Four females. General color greenish mottled with dark brown. Head with front retreating; fastigium of the vertex small and declivent, not nearly as broad as the basal segment of the antenna and apically pointed, the whole sunk deep between elevated antennal scrobae, the tip below that of the frontal fastigium, which is apically tuberculate; basal segment of antenna armed on the inner side with a long spur, more than half as long as the segment. Pronotum sub- sellate, without lateral carinae, the disk anteriorly roundly produced, posteriorly less so, the surface uneven but scarcely ruggose, the transverse sulci very distinct; lateral lobes twice as long as high, the lower margin horizontal and with a shallow intromarginal sulcus, Abdomen plump, the ovipositor heavy, very little curved upwards, lower margin regularly curved, the upper margin straight in basal half or a little more and then tapering to the pointed apex in an almost straight line, the margins almost smooth, very slightly undulately toothed. Legs long and stout; all the femora armed beneath on the cephalic margin only, the fore ones with four, the middle with five or six, and the hind ones with about a dozen stout spines, those of the hind femora especially much flattened; all geniculations briefly but acutely spined; all tibise armed beneath on both margins with several short stout spines; fore tibie unarmed above or with one or two small spines on the caudal margin in the apical half, none apical; middle tibie armed above on the caudal margin only with 4 or 5 494 PROCEEDINGS OF THE NATIONAL MUSEUM. vou, 47. spines, none apical; hind tibiz with both dorsal margins bearing long, basally flattened, backward curving spines, an apical one on the inner margin only. Tarsi broad and flat, especially the third segment. Elytra slightly longer than the wings when folded, extending a fifth their length beyond the tips of the hind femora; costal and anal margins almost equally and uniformly curved, the tips narrowly rounded. Wings nearly as broad as long, uniformly and deeply fuliginous with even darker cross-veins except a broad grayish-brown strip along the costal margin and extending from the base to near the apex and as broad mesially as the pronotal width. Face, like the entire head except the brown eyes, light yellowish brown, the mandibles blackish apically and the clypeus and labrum very slightly margined laterally with darker color; antennz brown, with some lighter segments here and there. Abdomen generally yellowish brown, the sides of the last segment shining piceous, the ovipositor yellowish basally and black apically. Legs greenish brown mottled with black, the black mottling of the tibize sometimes gathered into the form of illy defined obscure bands. Elytra green- ish with blackish mottlings; wings colored as described above. Length: Pronotum, 10 mm.; fore femora, 18; middle femora, 17; hind femora, 37; elytra, 65; wings, 57; ovipositor, 37. Width: elytra, at the middle, 18; wings, at widest part, 46; ovipositor, at middle, 5.5. Type.—Cat. No. 18252, paratype No. 18252a U.S.N.M.; paratypes 182526 and 18252¢ Yale University. The paratypes are about as the types except that the general color is dark brownish, the green of the type specimen being mostly absent. The armature of the anterior tibie seems very variable. In the type-specimen and paratype a one of these tibie, the left, is wholly unarmed above while the opposite one has one small spine at about the apical fourth. Paratype 6 has the left with one small spine and the right unarmed and paratype ¢ has two spines on the left one and one on the right. In general this species bears some superficial resemblance to the insect described and figured by Redtenbacher as Bliastes striolatus but in structure it is very different. LUTOSA CUBENSIS Haan. One female. Family GRYLLIDAE. CRYPTOPTILUM ANTILLARUM Redtenbacher. Two females. The measurements of these two specimens are somewhat less than those given by Redtenbacher for the types from St. Vincent and the form is a little more slender than United States specimens in the National Museum collection determined by Rehn No. 2058. ORTHOPTERA FROM DOMINICA—CAUDELL. 495 and Hebard. But these Dominican specimens are badly rubbed and show some indications of immaturity. ANUROGRYLLUS MUTICUS DeGeer. One female. The lateral lobes of this brachypterous specimen are almost wholly blackish, showing variation toward the larger A. fuscus Caudell from Peru. This latter species may prove to be but of varietal distinctness. An interesting malformation of the male type of this Peruvian form is presented by the metatarsus of the left hind tarsus, which is unarmed above. GRYLLODES RUFIPES Redtenbacher. One adult female and three nymphs, one a nearly mature female and two smaller males. The adult female, which has the end of the ovipositor broken off, agrees with the original description of the species except that the elytra are not separated above. This may indicate a different species, a variation or a difference due merely to a shriveling of the type specimen in drying. This can be definitely determined only when more material from the Lesser Antilles is available for study. LARANDUS MARMORATUS Redtenbacher. One female. This specimen, the first of its sex known I believe, seems to resemble the male, as described by Redtenbacher from St. Vincent, except that it is entirely apterous and measures as follows: Length, pronotum, 38 mm.; posterior femora, 11; ovipositor, 7; width, pronotum, 3.5; hind femur at widest part, 3.25. The ovipositor is moderately curved upward and the tip is con- siderably broadened and spear-shaped, the valves almost unarmed. The cerci are almost one half longer than the ovipositor. CYRTOXIPHA IMITATOR Saussure. One male. This specimen seems specifically identical with the male recorded by Rehn from Cuba. AMPHIACUSTA CARAIBEA Saussure. One male. OROCHARIS, species. Two males, one female. In spite of the fact that these specimens are in fairly good condition I am unable to place them with certainty. They are probably what has been sometimes recorded from the Antilles as Orocharis gryllodes or O. saulcyr but they differ from both these species as represented in the collection of the United States National Museum. Orocharis, like so many of our orthopterous genera, is in need of revision. he i ee Ait hay 5 - ths: ay TY. b. i: Vat { thay tei rian ey eS Pon Jy eae Bi — V es Fy a ard es eo a Lea ieee i LH “rhe te! wr Ss nat tsiee uals Lb nite 4 Pt - Li ms tad, a spits) ‘ re Bik am ; 7 Hint iia rich) rd uf heard: iby ha!

By ALEX WETMORE, Of the Biological Survey, United States Department of Agriculture. Sometime ago Dr. C. W. Richmond, of the United States National Museum, called my attention to certain peculiarities in the rectrices of the Giant Hornbill (Rhinoplax vigil) and the following notes are the outcome of his kindness in allowing me to examine the material under his care’. Nine specimens, six males and three females, of this fine bird are at hand, all collected by Dr. W. L. Abbott. In none of these are the rectrices perfect as will be noted in the detailed description below, and it was this fact that first drew attention to them in Doctor Richmond’s search for a specimen to be mounted and placed on gen- eral view. The elongated median tail feathers at once catch the attention on examining this Hornbill, and their length is no less extraordinary than the apparent manner of their growth to which I believe attention has not been called previously. Ten rectrices are found in the completely developed tail of this bird, eight outer feathers of moderate size and two central feathers, which when completely developed, are from 2 to 3 feet in length. The only apparent difference between male and female in the growth of the tail is that of relative size, the male being the larger bird. Following is a brief description of the condition of development of the caudal feathers in the specimens at hand, arranged in chrono- logical sequence: Cat. No. 159447, U.S.N.M.; female; Lay Song Hong, Trong, Lower Siam, September 16, 1896. The eight lateral tail feathers are all present but of the central pair, one long feather, faded in color and somewhat worn, is developed. On the right side a second long feather, bright and new in color, is growing with its tip about one and one-half inches beyond the shorter lateral feathers. Cat. No. 159448, U.S.N.M.; male; Lay Song Hong, Trong, Lower Siam, September 24, 1896. The eight outer rectrices are fully crown and one long central feather somewhat worn appears on the left side. 1 To Mr. H. C. Oberholser thanks are due for suggestions during the preparation of this paper. PROCEEDINGS U. S. NATIONAL Museum, VoL. 47—No. 2059. 34843°—Proc. N.M.vol.47—14——32 497 498 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. Its coordinate on the right has attained two-thirds the length of the lateral retrices. Cat. No. 181104, U.S.N.M.; male; Aru Bay, East Sumatra, Novem- ber 18, 1905. In this bird seven of the lateral paired feathers are fully developed with an eighth outermost just appearing on the right side, while its mate on the left has evidently been fully developed for some time. The fourth from without on the right is a bright clean feather which has not quite attained its growth, a small portion at the base being still inclosed in a sheath, while the corresponding feather on the left is old, much worn, abraded at the tip, and dull in general color. Of the central pair, the left feather is longer and is faded and much worn, while the right rectrix, 6 inches less in length, is still growing as is shown by the sheath-inclosed base. Cat. No. 159449, U.S.N.M.; female; Lay Song Hong, Trong, Lower Siam, November 21, 1896. The four outer pairs of rectrices are developed normally, while one alone of the central feathers is fully grown and it is faded and somewhat abraded. At its base on the left side is the other member of the median pair, a bright, new, developing feather three-fourths as long as the outer rectrices. Cat. No. 181105, U.S.N.M.; male; Aru Bay, East Sumatra, January 1, 1906. The eight shorter feathers. are intact and comparatively new. The right member of the central pair is fully developed and in fair condition as regards color and abrasion; while its companion on the left is one-fourth the length of the lateral rectrices and has just broken its sheath. Cat. No. 180966, U.S.N.M.; male; Tarussan Bay, West Sumatra, January 9, 1905. The tail is well developed, the four outer pairs of rectrices being entirely bright and new. One long feather on the right side is comparatively new, showing few signs of wear. Its companion on the left shows only in that the sheath projects one-half inch beyond the skin of the pygal elevation and as yet shows no sign of breaking to allow the vane to expand. Cat. No. 181699, U.S.N.M.; male; Balik Papan Bay, East Borneo, February 9, 1909. This specimen has three of the outer feathers on the left side fully developed, the second from the outside being one- third as long as the others. On the right half only two feathers are fully developed; the first is just breaking its sheath and the second is one-half as long as its fully grown companions. Of the median pair, the left is longer while its parallel on the right is a trifle shorter and is evidently older and in poorer condition, being worn at the tip nearly to the shaft. Cat. No. 181249, U.S.N.M.; male; Sungei Makapan, East Sumatra, February 18,1907. The right member of the fourth pair barely shows as a projecting quill from the uropygium, while its companion on the left is double its length and is just breaking the tegumentary sheath. no. 2059. TAIL, FEATHERS OF GIANT HORNBILL—WETMORE. | 499 The central feathers are identical in condition with those in the bird immediately preceding except that the right rectrix is the longer and younger as is shown by its color and condition as regards wear. Cat. No. 181250, U.S.N.M.; female; Makapan, East Sumatra, February 20, 1907. The eight lateral tail feathers are present and but one fully developed central feather on the right side, which has the vane faded and broken below the distal extremity. On the left its mate has grown out until it is 44 inches longer than the lateral rectrices. It will be noticed at once that in none of these nine birds which have been critically examined are both feathers of the central pair equal in length, apparent age, or development. In the three birds (Nos. 181104, 181699, and 181249) in which both feathers are approxi- mately the same length one of them is noticeably a feather of a pre- vious molt which is about to be shed and which is so worn and abraded that part of the shaft has been broken off, leaving it shorter than the newer feather. The other specimens all have one central feather fully grown and the other at different stages of development from a newly appearing pin feather barely projecting beyond the flesh to a bright new feather more than three-fourths the length of its companion. From these facts it is evident that but one of these feathers is devel- oped at one time. This feather grows to full length and is retained at the next molt while another starts on the opposite side. When this second feather attains its growth the two are found together for a short time until the old rectrix is shed, leaving the newly devel- oped feather as a projecting vane in the tail, when the process is repeated. Curiously enough each new feather, whether on the right or left side, grows out beneath the vane of the older feather, thus securing protection from abrasion and fading until mature. The long feather is apparently dropped sometime between Decem- ber and March, though I have not been able to ascertain the exact time or the age which these feathers attain, as the nine birds studied come from four separate localities, and different climatic conditions undoubtedly modify the breeding season and so change the time of the post-breeding molt. However, between September and January six birds are found to have these feathers of unequal length and in two specimens collected in February the new feather is fully grown and the other still in its place, while signs of growth are present in the other feathers, pointing to a duration of two years for each of these giant rectrices, though it may be found that they are renewed at shorter intervals, each one, however, being retained more than a year. It is very evident that these feathers remain in position for more than one year, from the great wear and fading which they show when com- pared with the other tail feathers and the remiges. 500 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47. Other irregularities are apparent in the molt of the bird as in four specimens from eastern Sumatra taken from September to February one or more primaries is found to be in an undeveloped condition, and variation is shown in the renewal of the shorter pairs of lateral rectrices. To summarize, in the Giant Hornbill (Rhinoplax vigil) but one feather of the central pair is developed at one time and this spike, much longer than the other rectrices, on reaching maturity, remains in position for more than a year, probably for two. Its companion, beginning its growth after the other has gained its extreme length, then equals it in size. The first feather is then molted and is gradu- ally replaced by another, so that in the renewal of this central pair there is a continual alternation instead of the usual method by which these feathers are renewed synchronously on the right and left sides. It is difficult to determine how this peculiar situation has been brought about, but it is apparently an interesting case of aberrant evolution. Upon the facts as outlined above, we may, however, base the hypo- thesis that originally a Hornbill with tail feathers more or less equal in length, through some accident retained a central feather which grew, outstripping its fellows until it had more than doubled their size and then later was cast off. In the meanwhile its companion attained an equal length, reaching maturity before the fall of the first feather and, remaining in position, maintained the peculiar spike-like form unique in this genus among the Hornbills. That this change has been rather recent is testified by the fact that these long central feathers have a broad white tip and a black subapical band conform- ing exactly in width and color to the bands found on the shorter lateral feathers. 1Since this was written three additional specimens of this Hornbill, collected by Mr. H. C. Raven, have been received from Borneo, as follows: Cat. No. 182804, U.S. N. M., adult male, Sungei Karangan, October 28, 1913; Cat. No. 182805, U.S. N. M., young female, Sungei Karangan, December 8, 1913; Cat. No. 182806, U. S. N. M., adult male, Sungei Pelawan, January 5, 1914. The two adult males exhibit the same peculiarities as the series discussed above. In each bird one of the central rectrices is worn and abraded, while its companion is bright and new. In the October speci- men the new feather is three inches shorter than its older companion, while in the January bird the two are about equal, and the older feather would soon have been dropped. Great interest, however, attaches to the development found in the immature specimen. This bird is about three-fourths grown, the primaries are still shorter than the secondaries and are worn and dirty, as though the bird had recently left the nest, and the huge knob on the culmen is in the early stages of growth. In the tail THE SAME CONDITION IS NOTED ASIN THE ADULTS. The right feather of the central pair of rectrices is worn and broken, one third being gone. The left rectrix while worn is evidently a newer feather. As in the adults the new feather grows out under the old one. From this it is evident that a single median tail feather grows out to full length while the bird is STILLIN THENEST. Whether another feather appears with it to be pushed out by one following later can be determined only from more material. NOTES ON WOLFRAMITE, BERAUNITE, AND AXINITE. By Epear T. WHERRY, Assistant Curator, Division of Mineralogy and Petrology, United States National Museum. OBSERVATIONS ON WOLFRAMITE. The studies herein presented were undertaken at the suggestion of Mr. Frank L. Hess, of the United States Geological Survey, who desired information as to the composition of these two occurrences of wolframite. No. 1 is a large specimen in the exhibition collection of the Museum (Cat. No. 80179), labeled “Cornwall, England,” although unfortu- nately with no statement as to the exact mine or district from which it came. It shows, however, the characteristic features of the min- eral as found in that region, occurring as long bladed crystals, with granular chalcopyrite, in white vein quartz. Along cracks in the solid wolframite a yellowish powder is developed, which apparently represents an alteration product, although the amount is too small to determine its character. No. 2 is a mass about 6 by 9 by 12 cm. in size, showing a very black wolframite intimately associated with bright green chrysocolla, with here and there between the two, as well as throughout the wol- framite, streaks of an olive green, waxy, copper tungstate mineral. The associated gangue minerals are microcline and gray quartz, the occurrence being evidently in a pegmatite vein. It came from Cave Creek, north of Phoenix, Arizona, and was presented to the Museum by Mr. S. H. Brockunier, through Mr. Hess (Cat. No. 87283). Material for analysis was selected from portions free from visible impurities, finely powdered and dried in a dessicator over sulphuric acid. Preliminary trials of the method of distillation in a stream of sulphur monochloride mixed with chlorine, recently recommended by Bourion,! gave rather unsatisfactory results in that it was ex- tremely difficult to recover all the tungsten, some of it sticking to the glass apparatus, and further, although most of the manganese and all the silica, calcium, copper, and magnesium remained behind in the boat, some iron was also left, so that it was necessary to run 1 Ann, chim, phys., ser. 8, vol. 21, 1910, p. 87. PROCEEDINGS U. S. NATIONAL MUSEUM, VoL. 47—No. 2060. 501 502 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47, both the residue and the distillate through the whole course of analysis. The method of fusion with sodium carbonate as outlined by Tread- well’ was therefore adopted, although modifications had to be introduced to obtain the copper in No. 2. The rare metals were also separated by the course recommended by Treadwell, that of decomposition by nitro-hydrochloric acid. It was found that on washing the residue insoluble in ammonia with pure water, the oxides of columbium and tantalum tended to become colloidal and run through the filter paper, a turbid filtrate under these conditions constituting a very delicate test for their presence; adding a little ammonium nitrate to the wash water coagulated them again, how- ever, and permitted their retention on the filter. In sample 1 the unusually high value of 0.80 was obtained for calcium. As it seemed of interest to know whether this was due to included calcite gangue, or to scheelite, half a gram was ignited for 30 minutes in a platinum crucible at the highest temperature of a modern complete combustion burner, and tested with neutral phe- nolphthalein solution. Not the slightest alkalinity was shown, although calcite should have been readily decomposed under these conditions. It was then thought that treatment with tartaric acid might throw some light on the question. Half a gram of the sample was heated on a steam bath with a solution of 10 grams of tartaric acid in 50 ec. of water for three hours, the undecomposed mineral filtered out, and ammonium hydroxide and ammonium oxalate added to the filtrate. On standing overnight a precipitate of cal- cium oxalate came down, which on being filtered out, ignited, and weighed, gave 0.82 per cent, showing that all the calcium had gone into solution. In the filtrate from the calctum oxalate ammonium sulphide gave a black precipitate of ferrous sulphide, which was filtered out, dissolved in hydrochloric acid, and its iron precipitated with ammonium hydroxide and weighed as ferric oxide. A small amount of manganese oxide, determined as 0.07 per cent, was also recovered here. The filtrate, from which iron, manganese, and calcium had now been completely removed, was evaporated to dry- ness three times with concentrated nitric acid to destroy the tartaric acid, and the separated tungsten trioxide dissolved off the dish with ammonium hydroxide, and poured through a filter into a crucible in which it was ignited and weighed as tungsten trioxide. The amount of tungsten trioxide obtained was not sufficient to satisfy all of the bases, but it seemed most probable that it had ia united with all of the calcium and part of the iron. To determine whether scheelite is soluble in tartaric acid, some clear crystals were broken from a specimen from Zinnwald, powdered, and 1 Quantitative Analysis, translated by W. T. Hall, 3d edition, 1911, p. 296. no. 2060. WOLFRAMITE, BERAUNITE, AND AXINITE—WHERRY. 5Q3 0.2250 gram heated on the steam bath with 10 grams tartaric acid dissolved in water, for two days. The amount of powder was seen to gradually decrease, and that remaining at the end of this period weighed only 0.0302 gram, representing thus only about 15 per cent of the origi- nal material. This would no doubt have dissolved completely had it been finely enough powdered, or had the heating been continued longer, so it is evident that scheelite is essentially soluble in tartaric acid. This reagent therefore can not be used to differentiate scheelite from calcite as an impurity in wolframite, but in the present case the failure to obtain an alkaline reaction on ignition seems clear evidence of the absence of calcite, so the calcium has all been regarded as in the scheelite form. As noted in the description of the mineral, a yellowish powder is visible in some cracks on the specimen; although every- thing of this sort was carefully removed from the material used for analysis, the presence of invisible cracks along which incipient altera- tion by calcium-bearing solutions has occurred is quite within the range of possibility. The tartaric acid dissolved from the wolframite 4.16 per cent of tungsten trioxide. The 0.82 per cent of calcium oxide found would be united with only 3.40 per cent, if in the form of scheelite, so that 0.76 per cent tungsten trioxide remains to be accounted for. But 0.90 per cent ferric oxide and 0.07 manganous oxide were also found to be dissolved. The manganous oxide would take 0.23 tungsten triox- ide, leaving 0.53 which was united with ferrous oxide. The amount of ferrous oxide corresponding would be, however, only 0.17 per cent (0.20 as ferric oxide), which, subtracted from the total ferric oxide found, leaves 0.70 free ferric oxide which was dissolved by the tartaric acid. This, which is perhaps present as limonite, has been listed separately in the analysis, the equivalent amount of ferrous oxide, 0.63 per cent, having been subtracted from the total ferrous oxide found. But on calculating the mineral composition of the original material, following Mr. Hess’s plan of assigning the tungsten first to the manganese, calcium, magnesium, etc.,! a total excess of ferric oxide of 2.2 per cent was found. Since the form of the remaining 1.5 per cent of this is indeterminate, it has been necessary to include it with the ferrous oxide, although it may be present as a ferric oxide insoluble in tartaric acid, perhaps hematite, or possibly in solid solution (see below). Mr. Hess ? has found such an excess of iron to be very frequent in wolframite. No. 2 was fused with sodium carbonate at as low a temperature as possible, to prevent alloying of any of the copper with the platinum crucible, and then, when the oxides insoluble in water were dissolved in acid, the copper was first precipitated by hydrogen sulphide before the determination of the iron and manganese, and weighed as oxide, 1U.S. Geol. Sury., Bull. 583, 1914, p. 21. 2Idem, p. 38. 504 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47, after repeated ignition with dry ammonium carbonate. Here the cal- cium was only moderate in amount, but the columbium and tantalum oxides seemed sufficiently high to attempt to determine the relative amounts of the two. For this purpose the oxides were fused with potassium acid fluoride, reprecipitated, and ignited as recommended by Foote and Langley ! and the specific gravity then determined. Although the impossi- bility of duplicating the conditions exactly renders the result uncer- tain, it is probably quite as dependable as that obtained by any of the direct methods of determination. The 2.20 per cent of mixed oxides obtained had a specific gravity of 7.02, corresponding to about 2/3 tantalum, so that the percentages of the two oxides are stated as tan- talic oxide 1.50, columbic oxide 0.70. No tin or titanium could be detected in either sample of wolframite. Analyses.

Wolframite, Cornwall, England. U.S. Geol. Surv., Bull. 583, p. 27. 2. Wolframite, Cave Creek, Arizona. Idem, p. 32. In calculating the approximate mineral composition of 1 it was assumed that the only free base was the iron oxide, that the iron manganese ratio was the same in the columbite-tantalite as in the wolframite, and that equal proportions of columbium and tantalum were present. In calculating that of 2 it was again assumed that the iron and manganese were present in the columbite- tantalite in the same ratio as in the wolframite, and that the deficiency in the summation of the analysis was due to the manganese being too low. A few words should be added concerning the nomenclature here adopted.?, The names wolframite, scheelite, columbite, and tanta- lite are used as series names, that is, as referring to any and all inter- mediate members of the isomorphous series, no matter what the relative proportions of the basesare. For the theoreticalend members, chemical prefixes are applied to these roots.’ This method is pre- 1 Amer. Journ. Sci., ser. 4, vol. 30, 1910, p. 393. 2 Which represents an extension of that proposed in Science, vol. 39, 1914, p. 575. 3The end members are described as theoretical because they can not be expected to occur in nature, elements being apparently never found free from at least small amounts of their isomorphs. Their chemical-prefixed names should therefore not be included in ‘‘lists of new mineral names.’’ no. 2060. WOLFRAMITE, BERAUNITE, AND AXINITE—WHERRY. 505 ferred to the use of distinct names for the end members because, while both are ambiguous in being ordinarily used for quite distinct things, it seems simpler to restrict the chemical terms to one mean- ing. Thus, both ferrowolframite and ferberite may be used either for pure ferrous tungstate, or for a ferrous tungstate containing a lit- tle manganese isomorphously replacing the iron; manganowolframite and hiibnerite for either pure manganese tungstate or manganese tungstate containing a few per cent of iron in isomorphous replace- ment; cuproscheelite and cuprotungstite for various mixtures of cop- per and calcium tungstates, etc. If mineralogy is ever to have anything like a quantitative system of nomenclature, such ambiguity will have to be avoided, and it seems to the writer that the best way to avoid it will be through restricting the use of words with chemical prefixes to the end mem- bers, whether found in nature or not, and doing away with distinct names for them. The method used in the well-known quantitative classification of igneous rocks could be adopted here, using the pre- fixes: Permangano when Mn: Fe is greater than 7: 1; domangano between 7:1 and 5:3; ferromangano between 5:3 and 3:5; doferro between 3:5 and 1:7; and perferro less than 1:7. Named according to this plan, the wolframite from Cornwall would be ferromangano- wolframite and that from Cave Creek doferrowolframite. Such names are of course too cumbersome for everyday use, although it is possi- ble that in certain cases they might be employed with advantage for purposes of classification or comparison. It is especially urged, however, that they, like those of end members, be omitted from lists of mineral names, for arbitrarily partitioned-off portions of isomor- phous series are not to be regarded as definite minerals. It is of course impossible to refer in the names to all constituents of the minerals, but that does not mean that some of the minor ones are not of considerable importance; and the significance of the colum- bium and tantalum found in these samples is certainly worth dis- cussing. In the table of calculated mineral compositions these have been regarded as united with iron and manganese, to form the colum- bite and tantalite molecules. No columbite and tantalite are present as Visible inclusions, for the brilliant cleavage surfaces of the wolfram- ites look perfectly uniform under the microscope. But they might exist either 1, in chemical combination; 2, as submicroscopic inclu- sions; in one of the types of solid solution: 3, isomorphous replace- ment; or 4, mix crystals; or, finally, 5, as an adsorption compound. The tendency of the ‘‘metallic acids’”—columbium, tantalum, tita- nium, tungsten, vanadium, etc.—to enter minerals in these ways is very evident when the variability in composition of many colum- bates, of the titaniferous magnetites, etc., is considered. But vari- ous interpretations have been put on it by different observers. 506 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. 47. Thus Dr. J. T. Singewald, jr.,1 concluded that the presence of titanium in magnetites showing no visible ilmenite intergrowths proved the existence of a ‘‘titanomagnetite”; but he had found the lamellas of ilmenite to vary continuously from 4 mm. down to 0.001 mm. in length, and there is no reason at all why they should cease to exist at just the latter size, for the limit of microscopic visibility is determined by the wave length of light, and has no significance as far as the molecules are concerned, a particle of this size containing thousands of molecules. So submicroscopice inclusions may well account for much of the titanium. Stopford Brunton,’ from similar studies, assumed the titanium to be present in “solid solution,” but evidently used this term to cover all cases where no inclusions are visible, making no attempt to differentiate the various possibili- ties listed above. It seems to the writer that we should be more specific in stating just what mode of combination the evidence favors in any particular case, so the data in regard to wolframite will be further discussed here. The absence of the elements columbium and tantalum from some specimens of the latter mineral, and their variable amount when found, clearly indicate that they are not chemically combined with the tungs- ‘tates. That their presence might be due to inclusions of columbite and tantalite has been suggested,’? without definite proof; and only the existence of visible inclusions would justify the assumption of submicroscopic ones, as in the titaniferous magnetites above men- tioned. There remain, therefore, only the possibilities of solid solu- tion and adsorption, 3, 4, and 5. A solid solution, according to van’t Hoff, the first to employ the term, is a solid homogeneous complex of two or more substances, the relative proportions of which may vary, but the homogeneous charac- ter be retained.t| Two principal types can be distinguished, isomor- phous replacement, where the substances are closely related chemi- cally and may be regarded as taking one another’s places in the point system constituting the crystal structure; and mix-crystal forma- tion, where the substances are so different in character that mutual replacement is out of the question. The formation of mix crystals, in which, as has been shown more especially by O. Lehmann,’ two or more crystalline substances grow together so intimately that they appear homogeneous under the microscope, yet mutually affect one another as to crystallization, producing changes in habit, crystal angle, optical properties, etc., is probably a much more frequent and important phenomenon than is ordinarily supposed. It takes the 1 Econ. Geol., vol. 8, 1913, p. 207; U. S. Bureau of Mines, Bull. 64, 1913. 2Tdem, p. 670. 3 Damour, Bull. soc. géol. France, ser. 1, vol. 2, 1848, p. 108; Hess, loc. cit. 4 ZeitS. phys.

WOLFRAMITE, BERAUNITE, AND AXINITE—WHERRY. 507 place in crystalline substances that adsorption does in colloids, and, indeed, is probably the same effect. At least it is among the elements the compounds of which show the greatest tendency to take on the colloidal form that mix crystal formation is most frequent. Tungsten and columbium are alike only in that both can act as anions toward the more strongly electro-positive elements, and dif- ferent in practically every other chemical property—in valence, behavior with reagents, etc.—so that they can not be expected to replace each other isomorphously. The most reasonable explanation of the condition of the columbium and tantalum oxides in wolframite is, then, that they are present as mix crystals, or, in other words, that the several point systems have interpenetrated to such an extent that they have become at least pseudohomogeneous.' Wolframite is of course not susceptible to optical examination, nor can any crystal angle measurements be made on the present specimens, but if they could be so studied effects such as those shown by other mix crystals would no doubt be observed. Such intergrowth produces marked effects on the crystal angles of the columbite group of minerals, which, as will be more fully explained elsewhere, are probably to be regarded as composed of mix crystals of a very few fundamental compounds; the principal ones, the compositions of which are R’’Cb,O, and R’’Ta,0,, are trimorphous, having isometric, tetragonal, and orthorhombic forms; so that, even admitting that the analyses of members of this group are to some degree correct, the number of “species” into which it should be separated is greatly overestimated. In summary, two wolframites have been analyzed and their compo- sitions discussed, astandard nomenclature for such isomorphous mix- tures recommended, and the columbium and tantalum oxides found shown to most probably exist in mix crystal form. A NEW OCCURRENCE OF BERAUNITE. The rare iron phosphate beraunite was discovered near Hellertown, Northampton County, Pennsylvania, by the department of geology of Lehigh University in 1911. The exact locality is the northeast corner of an abandoned iron-ore pit, 1 mile southeast of the center of the town. It was analyzed by Mr. J. S. Long, assistant in the department of chemistry, and later more thoroughly studied by Mr. Louis H. Koch, assistant in mineralogy, as part of the work for his degree of master of science at Lehigh. Specimens were brought by the writer to the United States National Museum (Cat. No. 87284), and further investigated and the combined results of all the work are here presented. 1The apparent excess of iron oxides, if not due to analytical errors, may be explained in the same way, which would be favored by their similar crystallization: Prior, Mineralogical Magazine, vol. 13, 1903, p. 217. 508 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, 47. The material shows a deep brown nodular crust up to 5 mm. thick, and flat radiations up to 1 cm. in diameter, on the surface of an iron-stained quartzite. In some specimens it bears implanted globules of psilomelane, yellow needles of cacoxenite, and powdery clay. Internally the crusts are coarsely fibrous, with the fibers perpendicular to the surface, and the material was evidently origi- nally a gelatinous precipitate, which has become hard and crystalline in place, thus representing a ‘‘meta-colloid,’’ as defined by the writer in a recent paper.’ After a preliminary analysis (1) had shown the general nature of the mineral, material for further study was obtained by crushing selected fragments, and the powder looked completely crystalline and homogeneous under the microscope, except for the presence of a trace of clay or fine sand. Standard methods of analysis were used, the iron being determined with permanganate, the manganese by the bismuthate and the Ford methods, and the phosphorus weighed aS Magnesium pyrophosphate after separation by molybdate. A small amount of water—less than 0.5 per cent—was given off below 100°, and the analyses were made on coarsely powdered material dried at this temperature, for the fineness of the grinding and the humidity of the air were found to have a distinct effect on the water content.

WOLFRAMITE, BERAUNITE, AND AXINITE—WHERRY. 509 ever, with beraunite. The specific gravity, determined by a pycno- meter, varied from 2.850 to 2.920; Dana gives 2.95. The indices of refraction were found to be approximately @ and 8=1.78, ;=1.81, extinction straight (elongated parallel to b.), and sign of elonga- tion —. No optical data have been published for beraunite, but Dr. E. S. Larsen, of the United States Geological Survey, kindly exam- ined for comparison a specimen of the variety ‘‘eleonorite” (U.S.N.M. Cat. No. 80622) from the type-locality at Giessen, Germany, and obtained the values: w=1.775, @=1.786, y=1.815, which are essen- tially the same as those above given. Two possible explanations of the variation in composition shown suggest themselves. The first, that the law of definite proportions does not hold in this, and other iron phosphates, would be capable of introducing a rather chaotic condition into mineral chemistry, and seems entirely improbable. If the mineral were a colloid, how- ever, the results could at once be interpreted in a second way—that the mineral is an adsorption compound of ferric and manganic hydroxides with phosphoric oxide and water. It is, however, a meta-colloid, that is, a colloid which has become crystalline without dissolving or losing its solidity. If, when this crystallization took place, the adsorbed constituents united as well as they could into definite compounds which formed mix crystals (or, as it is often called, solid solution), the results obtained could easily be accounted for. The R,O,:P,0,; ratio shown here varies from 1.72:1 in No. 2 to 1.93:1 in No. 1, while that indicated by the best previous beraunite analyses is 1.50:1, and the best dufrenite analyses, 2.00:1. The simplest explanation of the variation and indefinite ratios shown by the specimens under investigation is that they represent mix crystals (solid solutions) of these two fundamental compounds. The dufrenite molecule is in excess over the beraunite, although the properties are those of the latter mineral; it might therefore be called dufreniberaunite. AXINITE FROM DELAWARE COUNTY, PENNSYLVANIA. In the pegmatite cutting the granite gneiss of the Leiper Quarry at Avondale, Delaware County, Pennsylvania, an occurrence of the min- eral axinite has been discovered, certain features of which are so unusual that it has seemed worth while to make it the subject of special study and description. It was in fact at first supposed to be a new mineral, and its true character was only recognized toward the end of the investigation. Specimen 1 (U.S.N.M. Cat. No. 87232) consists of three small frag- ments, showing @ columnar mineral with a resinous luster, of a pale yellow to salmon pink color, associated with pink microcline, granular 510 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. 47, quartz, and muscovite. It was found at the locality in 1904, and analyzed by the writer when beginning the study of quantitative analysis. The results, given in column 1a in the table below, showed it to have a composition distinctly different from that of any pre- viously known mineral, although, because of lack of experience, it is probable that they are not altogether accurate, some silica having no doubt been weighed with the sesquioxides, and some manganese with the calcium or magnesium; but the boric acid, having been determined by the writer’s volumetric method,! is probably exact. The matter was then laid aside because of the pressure of other work, but when the writer became connected with the Museum, it was taken up again. To obtain a check on the previous analysis, all the mineral that could still be broken from the specimens, amounting to less than half a gram, was sent to Mr. J. E. Whitfield, of the firm of Booth, Garrett & Blair, of Philadelphia, who has been doing considerable analy- tical work for the Museum, and his results are given in column 10. Meanwhile a mass of yellow plates, about 4 by 2 by 1 cm. in size, was found at the quarry by Mr. J. Watts Mercur, jr., of Wallingford, Pennsylvania. (U.S.N.M. Cat. No. 87233). Although showing no planes definite enough for crystallographic measurement, this ma- terial had the aspect of axinite, and the same specific gravity, 3.250. A clear fragment was sent to Mr. Whitfield for analyis, and he obtained the results in column 2a; but as the boric acid seemed rather low, probably owing to incomplete decomposition, two deter- minations were made by the writer, and 5.98 and 6.09, average 6.04, obtained (column 20). Using this value, the agreement with the theory for axinite is so close as to leave no doubt that it is the mineral represented. The question as to whether No. 1 was a new mineral, or only an im- pure axinite, remained unsolved, so powder from both specimens was submitted to microscopic examination. No.2 showed a mean index of refraction of 1.680, birefringence 0.008, and sign —, thus agreeing with typical axinite. The greater part of No. 1 gave essentially the same values, but scattered through this material could be seen pinkish, pleochroic grains with a much higher index, 1.700, but still lower birefringence, 0.005, showing, in fact, ultrablue interference colors, also extinguishing straight and + in sign. These properties identified it as zoisite, a mineral which had previously been reported from the locality.2, Here, then, was the explanation of the difference between analyses la and 10, as well as their deviation from the theory for axinite: the material is not homogeneous, but contains a variable 1Journ.

NORTH AMERICAN PARASITIC COPEPODS BELONGING TO THE LERNAEOPODIDAE, WITH A REVISION OF THE ENTIRE FAMILY. By CuarLes Brancn WILSON. Department of Biology, State Normal School, Westfield, Massachusetts. INTRODUCTION. The present is the eleventh’ paper in the series based on the collection of parasitic copepods in the United States National Mu- seum and deals with the family Lernaeopodidae. For several reasons the necessity of supplemental study has been greater than in connection with any of the families previously treated. The Lernaeopodidae are soft-bodied, without any chitin framework, external or internal, to hold theminshape. Consequently they shrink and often become so distorted during preservation that the museum specimen gives very little idea of the original. Most of the species are transparent when alive, and much of their internal anatomy can then be plainly seen. But ina preservative they become opaque and require dissecting or sectioning before anything can be learned with regard to their internal structure. Finally a knowledge of both sexes of the various genera, and of the developmental stages through which the larvae pass has been found necessary for the establishment of a rational basis of classifica- tion. And the greater bulk of such information must be obtained outside of a museum collection. The development of the family was worked out at Lake Maxin- kuckee, Indiana, during the summers of 1906, 1908, and 1909, and has already been published as the ninth paper of the present series. Isolated developmental stages and the males of many species were obtained at Beaufort, North Carolina, while working for the United 1The ten preceding papers, all of which were published in the Proceedings of the United States National Museum, are: 1.

For these excellent advantages the author is indebted to the courtesy of the Hon. George M. Bowers, former United States Commissioner of Fisheries. The internal anatomy has been derived partly from the study of living specimens at each of the above localities, and partly from serial sections made in the laboratory of Johns Hopkins University, as noted in the ninth paper above mentioned. A number of specimens, including several of the new species, were collected by Dr. Edwin Linton during his investigations on the cestode and trematode parasites of fishes, and were generously turned over by him to the present author. These specimens are always excellently preserved and have proved of great value in the present study. Several years ago Dr. R. R. Gurley, at that time in the employ of the United States Bureau of Fisheries, collected in manuscript form all the available data regarding copepods parasitic upon our North American freshwater fishes. These notes have been placed at the author’s disposal, and as they included complete translations of everything written on North American species by foreign authors they have proved extremely valuable. Acknowledgment is made in the text whenever these notes have been incorporated. Dr. Nathan Fasten, of the Department of Zoology at the Univer- sity of Wisconsin, has recently published three excellent papers on the habits and development of a species of this family which infests the common brook trout. At the author’s request Dr. Fasten very kindly loaned mounted specimens of the copepodid larvae and male of this species, Salmincola edwardsii, which have been of much use for study and comparison. As here constituted the family includes 23 genera and 136 species, of which 12 genera and 21 species are new to science. In addition there are several other genera and species which at one time or another have been included in this family, but which must be regarded as synonyms or as not sufficiently well established to be definitely located. ECOLOGY. Wherever the Lernaeopodidae may be placed in any scheme of classification, all authors will agree that they are fixed parasites and extremely degenerate. Consequently we should look for marked sexual dimorphism, a partial or total loss of the powers of locomotion, and a corresponding complexity in the means of prehension. And we find these abundantly exemplified. Sexual dimorphism.—The differences between the sexes manifest themselves not only in an enormous disparity in size, coupled with a corresponding dissimilarity in the structure of the body and its appendages, but also in the methods and extent of prehension and no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 567 locomotion. Such dimorphism as has to do with structure will be treated under morphology (see p. 571), while that which concerns locomotion and prehension follows under those headings respectively. Locomotion.—The larvae alone in this family possess the ability to swim about freely and that only for a remarkably short period, during which they must seek out a host and attach themselves to it. During this free stage the larva swims about actively with a jerky spiral motion by means of its two pairs of swimming legs. Fasten in his experiments with the brook trout parasite, Salmincola edwardsii, found that the average distance covered by a single contraction of the swimming legs was about an inch. When the motion ceased the larva at first took an upright position, then turned upside down and sank to the bottom where it lay as it struck, with either the dorsal or ventral side uppermost. It was also able by means of its first antennae to cling to the side of the aquarium, or to suspend itself from the surface film of the water. By means of its peculiar spiral locomotion it is enabled to cover the maximum of territory with the minimum of muscular energy. Female.—After the female larva has once become attached it can not loosen this connection and form another, but must remain in the same place all the rest of its life. If the arms (second maxillae) are short, as in many species of Clavella, scarcely any freedom of motion can be enjoyed. The parasite is not only fixed in position, but it can not turn or flex its body, and becomes fully as helpless as some of the Lernaeidae or Chondracanthidae, whose head and neck are buried in the flesh of their host. On the other hand, if the attachment organs are long and slender as in many species of Brachiella, Lernae- opodina, etc., while the tips of these arms remain at a fixed point the body of the parasite can describe quite an arc. The arms are sup- plied with powerful muscles which swing the body to one side or restore it again when once displaced. In this way the animal often escapes being brushed or scraped off from the fish, especially those species which attach theselves to the fins, where, of course, there is the greatest danger. After the female is once fastened to her host she loses during subsequent moults the two pairs of swimming legs which were all the locomotor organs she ever possessed. She finds excellent aeration for her eggs and a good position from whence to discharge the copepodid larvae when once they have matured. And there is also an abundance of food, so that she is well provided for during life. Male.—The free-swimming period of the male larva is no longer than that of the female, and the two often fasten themselves side by side upon the same fish. But while this attachment is permanent in the case of the female, it is only temporary for the male. When the two have become sexually mature the male, on swinging around upon its attachment filament and coming in contact with the 568 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL, 47, body of a female, lets go of the filament and fastens himself to the female by his second maxilae and maxillipeds, and remains upon her body for the rest of his life. Not being permanently fixed, he is able to crawl about over the female’s body, and is found sometimes in one position, sometimes in another. But such motion is slow amd laborious and probably is only practiced when necessary. Unlike the female the male does not always lose his swimming legs, but may retain them; they become very small and dwarfed, however, and lose all their swimming setae, so that they are no longer of any service as locomotor organs. Furthermore the male does not increase in size with successive molts like the female, but remains dwarfed, little if any larger than in its copepodid stage. The mating of the sexes in this family takes place upon reaching maturity, just after the molt at the close of the second copepodid stage. But the male may remain clinging to the body of the female long after this mating, sometimes possibly throughout the life of the latter. Prehension.—The organs of prehension are the second maxillae and maxillipeds. As explained elsewhere,! the copepodid larvae, both male and female, seize their host with the maxillipeds, rub the frontal margin of the head against the skin of the gill arch or fin until the outer end of the attachment filament is firmly glued in place by means of the adhesive fluid it contains. As the coiled filament is drawn out of the head, or subsequently, the larva grasps its inner end between the claws at the tip of its second maxillae. Fasten,? observing Salmincola edwards under the microscope, describes its attachment as follows: . . . ‘“As soon as the copepod comes in contact with the filament of the gill its mouth parts (max- illipeds) are inserted into the flesh, and by means of the powerful claw-like second maxillae it begins to rasp the filament until it forms a cavity within it. As soon as this occurs, the anterior portion of the copepod’s head, the frontal margin, is brought in contact with the cavity and the inclosed attachment filament is injected into the hole. The spherical mushroom body adheres to the flesh and the regenerat- ing tissue of the gill soon incloses it tightly, thereby fastening the organism firmly. The mouth parts are then withdrawn from the flesh of the gill filament. In this condition the parasite remains attached for a short time. Then the second maxillae detach the pos- terior region of the attachment filament from the head margin and they themselves become permanently attached to this end of the filament.”’ The exact time or even the method of attachment are specific or generic in significance. That which concerns us in dealing with the family is the fact that the larva is attached at the first by a frontal 1 Proc. U. S. Nat. Mus., vol. 39, p. 211. 2Journ. Animal Behavior, vol. 3, No. 1, p. 56. no. 2068, NORTH AMERICAN PARASITIC COPEPODS—WILSON. 569 filament. The proximal end of this filament is afterwards transferred to the second maxillae, which thus become the organs of prehension intheadult. The hold thus secured is retained by the female through- out life, the second maxillae gradually elongating and fusing with the filament. In most of the species these organs become so long that they entirely usurp the function of prehension, and leave the maxilli- peds out of commission, so far as holding the parasite on its host is concerned. In the male such fusion does not take place, but as soon as he has found a female the second maxillae release the frontal filament and are afterwards used in anormal manner as prehensile organs along with the maxillipeds. Accordingly in the male the second maxillae retain their original musculature, which is similar to that of the maxillipeds. And the male uses these two pairs of appendages in exactly the same manner, moving about the little that it is able by employing them alternately, grasping with the maxillipeds while it reaches forward with the maxillae and obtains a new hold, then releasing and reaching forward with the maxillipeds. In this way the organs serve the double purpose of prehension and locomotion, in fact all the locomo- tion of which the adult males are capable. In the female, on the contrary, the musculature of the second maxillae becomes highly modified. There is no further use for the claws, and so the muscles that would otherwise move them become atrophied. The rest of the muscles are gathered into long bands or bundles, which run the entire length of the maxilla and are strong enough to move the whole body. Such modified organs of prehension are, so far as known, peculiar to the females of the present family, and nothing like them is found in any of the other copepods. After being once attached the females are incapable of any further locomotion, even the sort practiced by the males so that neither pair of appendages can function for this purpose. If there were not some further use for the maxillipeds we should expect to find them dwarfed or degener- ated, but they retain to the full their shape and powerful musculature. This is because the female uses them in procuring her food. Ordi- narily her body hangs free from the host, supported solely by the second maxillae. In order to obtain requisite nourishment the head and mouth of the parasite must be drawn up to, and held in contact with, the skin of the host. This is done by means of the maxillipeds, and is fully as important a function as the one served by the second maxillae. Hosts.—This family of parasites is widely distributed amongst fishes in both salt and fresh water. Some of our best food and game fish are infested with them, and when they once obtain entrance to a stock pond, fish hatchery, or aquarium they usually multiply so rapidly as to become a serious nuisance, and may even kill the fish. 570 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. Their free swimming period is, of course, the only time that their enemies can get access to them, and this period is so brief that not many of the larvae are killed. But the brevity of this period also operates as a regulator to pre- vent the parasites from becoming too numerous. For unless they find a host during this period they quickly perish. The shorter the period, therefore, the fewer will be those whose search is successful. In the crowded confines of a stock pond, on the contrary, practically every larva is sure of finding a host. And all too often the gills of the fish become so crowded with parasites that they can not perform their normal functions, and the fish are suffocated. Among fresh- water hosts the various species of trout and salmon, the white fish of the Great Lakes region, and the bass and perch are the ones most infected, the parasites being confined to the two genera Salmincola and Achtheres. Among salt-water fish many members ot the large family of Gadidae, particularly the cod and haddock, the mullets (Mugilidae) the rays (Dasyatidae), the skates (Rajidae), and the sharks are the most com- mon hosts. Food.—These parasites feed upon the blood of their host, as is shown by the fact that they fasten to the gills or fins. They are also furnished with mandibles which were evidently designed for piercing the skin of their host, and whose margin is cut into saw teeth, which not only penetrate the flesh but also lacerate the wound and thus stimulate the flow of blood. Adult females are frequently obtained with their alimentary canal filled with blood, but the color of the latter is quickly removed by the digestive fluids. It is a question whether the male ever eats anything at all, and if he does, what con- stitutes his food. The following facts and considerations have an important bearing on this question: 1. The adult male possesses a pair of mandibles as large, as power- ful, and as suited for laceration as those of the female. He has also a well-developed esophagus and stomach, but in all those examined there is no trace of an intestine or anus. 2. There are no digestive glands connected with the alimentary canal, but the stomach is lined with large gland cells, which are filled with a liquid that undoubtedly aids in digestion. The abundance of these cells more than compensates for the lack of glands, and would be amply sufficient to digest such food as blood. 3. The excretory glands are exceptionally large and are provided with good-sized ducts. It would seem as if they could take care of all the residue that would be left undigested. 4. The male does not live on the body of the host, but clings tightly to some convenient place on the body of the female, and no specimens have ever been found on the fish’s gills, although repeated search has been made for them. Males have been found clinging to the second no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. Sl maxillae of the female, and it is possible that they can crawl] along these appendages to the fish’s gills and there obtain food. But that does not seem very likely, because there are many species in which the second maxillae are as long as the entire body, and a few species in which they are two or three times the body length. Such a distance would make a rather long journey for so slow moving a creature as the male, and if it was a case of traversing the distance or going hungry, 1t would most likely result in the latter. Possibly the male may be brought close enough to the gill when the female draws her body down to obtain food. At all events the male must derive what- ever food he eats from the. fish host and not from the body of the female. 5. The spermatophores attached by the male to the sexual open- ings of the female are large and contain a goodly number of sperma- tozoa. Probably a single pair of them would supply the female with sufficient spermatozoa to fertilize all the eggs she can lay during her lifetime. Furthermore, the careful study of the sexual organs of the male given on pages 590, 691, indicates that only a single pair of these spermatophores are formed. Hence it is unlikely that the male lives very long after fastening the first pair in place. 6. Both sexes necessarily go without food during the free swimming period, since their mouth parts then are only suited for obtaining food parasitically. During the second copepodid stage they both suck the blood of the fish upon which they have fastened. The female uses this food to increase greatly in size, as well as to develop her various organs. The male does not increase at all in size, but devotes all his food to the maturing of the spermatophores. After these are fully developed and put in place on the body of the female no more food is required unless a second pair is to be formed, and even then the amount of food demanded would be relatively much smaller. Onthecontrary, the female must have an abundance of food to ripen her eggs, to carry them in the external sacks until they hatch, and to form, ripen, carry, and hatch successive new batches of eggs. In view of these considera- tions it is reasonable to suppose that the duration of life for the male is much shorter than that of the female. He requires little, if any, food after he has transferred from the host to the body of the female. And the absence of an intestine and anus would insure the complete digestion and absorption of all the food taken previously. It seems probable, therefore, that the male does eat the fish’s blood while it remains attached to the gills, but that it gets no food after it has transferred to the body of the female. MORPHOLOGY. General body form of female-—Owing to the degeneration consequent upon fixed parasitism there has been a fusion and elimination of the various body regions. We can no longer distinguish a cephalon, a 572 PROCHEDINGS OF THE NATIONAL MUSEUM. VOL. 47, free thorax, a genital segment, and an abdomen as in the less degen- erate families. These are separated in the copepodid stages of development, and may then be discerned with comparative distinct- ness. But they are entirely lost in subsequent moults, and the body of the adult female usually shows only two regions, and even these are sometimes (Basanistes) so fused that it is difficult to distinguish them. The first region corresponds to the cephalothorax in other copepods, and includes the head with its antennae and mouth parts, the neck, which is sometimes half the entire length or more, and the organs of attachment, the second maxillae. The remainder of the animal is fused together to form the other region, which we may call the trunk and which thus includes the posterior portion of the thorax, the genital segment and the abdomen. In the copepodid stages the segmentation of the trunk is distinct, but it gradually disappears with maturity, until it becomes wholly lost in the adult (Clavella, Basanistes), appears only in the anterior portion of the trunk (Lernaeopoda), or is indistinct with a fusion of some of the parts (Achtheres). But even in those genera which exhibit the most complete fusion of the body parts the musculature is still broken at regular intervals, each of which indicates a point of segmentation. In some species of Salmincola, Clavella, etc., there is also a small knob at the posterior end of the trunk, which is well separated from the rest of the body and which has always been called an abdomen. But it is so rudimentary and insignificant when it does appear, and it is so often lacking that it would not be worthy of consideration as a separate body region were it not for the fact that we do find well-dif- ferentiated abdomens in the genera Achtheres and Naobranchia. Accordingly we must determine whether the knob is a true abdomen, corresponding morphologically to those in the two genera just men- tioned or whether it is simply a process. On examining serial sec- tions of Clavella uncinata we find that the anus opens on the posterior end of the trunk, ventral to the base of the process, while the intestine does not enter the process at all. There is an opening at the distal end of the process, and a tube leading through its center. But this is a sperm tube and leads into a sperm receptacle, which is dorsal to the intestine. The outgrowth, therefore, can not in any way be regarded as an abdomen, but is purely sexual im structure and function. And we would propose for it the name of genital process. To this knob the male clings while he fastens the spermatophores on its tip; from these spermatophores the sperms pass into the tube and thence up into the sperm receptacle. As further proof that this is not an abdo- men there are never any anal laminae on it, while they frequently do occur on the posterior end of the trunk (fig. 1). no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 573 The size of the process is somewhat proportional to the size of the male; in the genus Clavella both the male and the process are very small, while in Brachiella the males are large and the process is increased proportionally. In the cephalothorax the general relations and the varying struc- ture of the head, neck, arms, and trunk furnish very useful generic characters. We may distinguish first genera in which the head and neck are long and slender and flexed dorsally at an angle with the trunk. Thesecond maxillae may be in the same line with this elong- ated cephalothorax and of about the same length, the two standing across the anterior end of the trunk like the top of the letter T (Brachiella, Thomsonella, Brianella). Or the second maxillae may be much shorter than the cephalothorax and inclined at a different angle (Cla- vellodes, Clavellopsis, Naobranchia). Sometimes the cephalothorax is bent back so far that it rests against the dorsal surface of the trunk and the creature looks as if it were folded and hung from the bend of the fold (Cla- vella). And in one genus (new) there has been a fusion after such a bend- ing, and as a result the cephalothorax is attached to the center of the dorsal surface of the trunk and stands out at right angles to the axis of the latter, while the second maxillae areattached Fie. 1—Srction oF CLAVELLA UNCINATA toithe’ anterior‘end of the-trunk some *220¥2NE-4: ANUS; .00; GENIAL OBENING, gp, GENITAL PROCESS; sr, SPERM RECEP- distance from the base of the cephalo- TACLE; st, SPERM TUBE; i, INTESTINE. thorax (Clavellisa). In a second group we find genera in which the head and neck are shorter and stouter, and they either stand in line with the axis of the ‘ trunk or are curved over (not flexed at an angle) ventrally. Thesecond maxillae may also be short and stout and stand out at right angles to the trunk axis, and they as well as the posterior margin of the trunk may be hung with fimbriate processes (Thysanote, Thysanotella). Or they may be perfectly smooth while the posterior margin of the trunk is furnished with cylindrical processes (Brachiella, Eprbrachiella). Again the second maxillae may be long and slender and inclined at an acute angle to the trunk axis, either forward or backward. They may be entirely separate, each ending in a clasping process (Charopinus), or they may be joined by an ordinary bulla. In this 574 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. 47. latter condition the posterior margin of the trunk may be wholly with- out processes (T'racheliastes) or may have a single ventral pair (Para- brachiella) or a single dorsal pair (Charopinus). In the third group we find genera in which there is no neck at all; the head is short and wide and may be in line with the trunk axis or inclined to it. When the two are in the same line we may find a sin- gle pair of processes on the posterior margin of the trunk which are either ventral (Lernaeopoda) or dorsal (Lernaeopodina) to the egg strings. If there are no posterior processes (Vanbenedenia) the sec- ond maxillae extend straight forward, are rigid, and their base has been moved until they are virtually dorsal instead of ventral or lateral, and cover the back of the head. When the head and trunk are inclined to each other we find no posterior processes, but there may be an unpaired median genital process (Salmincola) like that in Clavella. Thesecond maxillae are also usually turned backward along the ventral surface of the trunk and their bases are connected around the posterior end of the head by a stout ridge. Calling the second maxillae by the common name of arms, these enlarged bases correspond to a pair of misshapen shoulders. Sometimes the trunk is covered with longitudinal rows of knobs or tubercles (Basanistes). Again there are neither knobs or shoulders, but there is a well-defined abdomen behind the bases of the egg strings (Achtheres). General body form of male.—The male never becomes fixed in posi- tion and hence does not usually show as much degeneration as the female. The second maxillae are never permanently attached by means of a bulla and so do not develop into long arms, but retain their claws and are very similar to the maxillipeds both in form and function. The trunk is distinctly segmented more often than in the female and is usually furnished at the posterior end with a pair of well-defined anal laminae. In some genera the cephalon and in others the whole body is cov- ered with a carapace, but in the majority of genera this is lacking. The male remains a pigmy and there is a greater disparity in size between the two sexes than can be found anywhere else among the © parasitic copepods. There is also a folding of the body in these males, but in a manner different from that just described for the females. In the female the cephalothorax was flexed either forward or back- ward and sometimes rested against the dorsal surface of the trunk, but there was no fusion of the two parts except in the single genus Olavellisa. ere in the males, on the contrary, the cephalothorax is always folded forward against the ventral surface of the trunk, and the two are frequently so thoroughly fused as to be indistinguishable. no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. SD The different genera show varying amounts of flexion and fusion and we may separate the types as follows: 1. The cephalothorax and trunk may be approximately in the same straight line, when of course there is neither flexion nor fusion. These are large males, a millimeter or more in length; the mouth tube, the antennae, and the first maxillae point forward in the same direction as the body axis, or but little inclined to it and the anal laminae similarly point backward; the second maxillae and maxillipeds extend outward at right angles to this axis. The trunk may be well segmented (Achtheres and Thysanotella), partially segmented (Lpibrachiella) , or wholly devoid of segmentation (Thysanote, Brachiella, and Vanbenedenia). There is a carapace coy- ering the entire body in Thysanote, a well-defined cephalic carapace in Brachiella, a poorly defined one in ELpibrachiella, and none at all in the other three genera. 2. The cephalothorax may be turned forward at right angles to the trunk axis, so that the mouth tube, the antennae, and the first maxillae point outward parallel with the second maxillae and maxilli- peds; the anal laminae usually point outward also, though they may point backward (Charopinus), or may even be turned dorsally (Lernaeopoda). The trunk may be well segmented (Charopinus, im- mature Lernaeopoda), or may show no signs of segmentation (Pro- brachiella, Parabrachiella, adult Lernaeopoda). Lernaeopoda has a dis- tinct cephalic carapace, Charopinus has a larger but less distinct one, while Parabrachiella and Probrachiella have no trace of any. 3. There may be two flexures, the mouth tube and antennae being parallel with the greatly reduced trunk, as well as with the maxillae and maxillipeds, while the posterior portion of the cephalothorax stands at right angles to all of them. This is found in the single genus Lernaeopodina, whose males are considerably smaller than those of the other genera already mentioned. We have here therefore complete flexion but no fusion; there is no carapace visible and the trunk shows no traces of segmentation. 4. There may be similar flexion combined with fusion so that we can no longer distinguish the body regions. The sexual opening is at the end of a rounded process just behind the second maxillae, and extending outward parallel with them, and the anal laminae have entirely disappeared. What was originally the long diameter of the body may still be longer than the transverse diameter (Naobranchia, Clavellopsis) or the latter may have increased sufficiently to exceed the former (Clavellisa, Clavellodes). The result in Clavellodes is peculiar; there is apparently an oblong body, squarely truncated at one end, with the mouth tube and all the appendages arranged along this truncation, parallel with the long axis. But this is really the same flexion that was seen in Lernaeopodina combined with complete 576 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47, fusion, so that the long axis is actually transverse and not longi- tudinal. . In Naobranchia the sexual process is as long as the maxillipeds and suggests very strongly the trunk of Lernaeopodina; there is also a carapace which covers the entire body. 5. Finally in the genus Clavella there has been an even greater flex- ion and fusion of the body, for now the sexual process is closer to the second maxillae and sometimes is carried forward to a point between them, so as to be concealed in side view. The transverse diameter is still longer than the longitudinal one, and there are no signs of any carapace. The eye.—None of the adults in any genus possess eyes; the eye in this whole family is extremely rudimentary, appears only for a short time during the development stages, and then entirely disappears.’ The appendages.—In the adults of both sexes there are six pairs of appendages, namely, two pairs of antennae, one pair of mandibles, two pairs of maxillae, and one pair of maxillipeds. The reason for regard- ing the penultimate pair as second maxillae is that they appear in early development in front of the suture which separates the head from the thorax, while the posterior pair appear behind that suture.” In the adult males of the genus Achtheres there may be also one or two pairs of very rudimentary swimming legs. But these are only vestiges of the developmental stages and probably disappear at the first molt after the male has attached himself to the female. Kurz claims (1877, p. 400) to have found in the female of Clavellisa emar- ginata on the posterior end of the trunk the rudiments of the last pair of swimming legs. Before admitting this claim we must consider - first the fact that only two pairs of legs appear during development and these are attached to the two anterior segments of the free thorax. If either of these pairs remained in the adult stage they must have migrated the whole length of the trunk in order to appear on its pos- terior margin. On the other hand, it would be rather strange for the rudiments of the fifth or sixth pair of legs to appear in the adult when only two pairs appeared in the developmental stages. Again, if Kurz’s three figures (pl. 25, figs. 8, 9, and 10) be carefully compared with respect to the orientation of the trunk, it will be seen that figure 8 (designated ‘‘Bauchansicht’’) actually represents the ventral surface of the trunk and the dorsal surface of the cephalo- thorax, except the head, which is turned in profile. In figure 10 (designated ‘‘vom Bauch gesehen”’) the cephalothorax has been turned forward out of its natural position, and we are actually looking at the dorsal surface of both cephalothorax and trunk. But this is 1 Proc. U. S. Nat. Mus., vol. 39, p. 204. .

The antennules or first antennae.—These are attached to the frontal margin of the head, between the bases of the second antennae and the proboscis, often somewhat more on the ventral than on the dorsal surface, but usually the most dorsal of all the appendages. In Tracheliastes and Basanistes they arise on the dorsal surface of the head and are not turned downward and forward as in the other genera. ‘They are extremely simple and are made up of three or four joints, more or less distinctlyseparated. The basal joint is the thickest and is fused with the head, the other joints are cylindrical and taper distally, and the terminal joint is armed with a few short nonplumose setae or spines. The antennae, or second pair.—These are characteristically modified in the present family. They arise from what may be termed the anterior corners of the head on either side; they are flattened laterally and turned forward and inward along the anterior margin of the head, until in some species their tips meet or even overlap at the midline. They are made up of a thick basipod and two short rami, one dorsal and one ventral; the endopod or dorsal ramus is usually much larger than the exopod, is thick and fleshy, unsegmented, and bluntly rounded at the tip, where it is armed with a few short spines or teeth (Charopinus, Achtheres, Brachiella), sometimes with olfactory cylin- ders (Clavella, sp.) or even with claws (Lernaeopoda, sp.). The exopod is slender and cylindrical, usually two-jointed, and is tipped with tactile hairs, olfactory cylinders, or a chitin claw. The claw is more common in the male, where these antennae serve as attachment organs, where they have a stout musculature, and where the claw sometimes shuts down against the terminal joint and is chelate in function. In rare instances in the female the two rami are arranged like the jaws of a chela and must function as a grasping organ (Lernaeopodina longvmana and Charopinus ramosus). The mouth tube or proboscis.—This is attached between the bases of the second antennae, is conical in shape, and is directed downward and forward against the skin of the host. Itis composed of an upper and an under lip; each side of the latter is split into two lamellae, between which is fastened the corresponding side of the former, so that the two lips are loosely joined along their lateral edges to form a closed tube. But they are not held together very firmly, and it is an easy matter to separate them with a needle (fig. 2). At the base of these lateral seams both lips are cut away a little to form a three-cornered opening through which the mandible projects into the interior of the tube. The under lip is somewhat larger than the upper and more spoon- shaped, so that its anterior end, around the mouth opening, is curved like a horseshoe. The upper lip is flatter, broadened at the base, and 34843°—Proc.N.M.vol.47—14——37 578 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. narrowed toward the tip, which is bluntly rounded and armed witha tuft of fine hairs, or with a short spine. Each lp is supported around its margin by a chitin framework, which is articulated with the chitin framework of the head, so as to allow the proboscis to move freely backward and forward. The anterior margin of the under lip around the mouth opening is also divided into two lamellae, of which the inner one serves to contract the mouth opening while the outer one is cut into a fringe along its free margin. The length and thickness of this fringe varies considerably in different genera and species. Usually it is more than half the width of the lamella, in which case the fringe looks as if it were made of stiff hairs standing in rows around the mouth opening. Again, the fringe may be so short “ss that it can only be detected with difficulty, and hence appears to be lacking (Naobranchia). When the proboscis is applied to the host for the purpose of drawing blood, this border- ing fringe, together with the rest of the mem- brane, is spread out around the tip of the proboscis like a sucking disk and probably assists in obtaining the blood. There are no chitin rods nor any supporting framework in this sucking border, as was Fig. 2.—CROSS SECTION OF PRO- clearly shown by Kurz. BOSCIS (DIAGRAMMATIC); upl, The mandibles are rigid chitinous blades, UPPER LIP; onl, LOWER LIP. . . . . ‘operating inside the proboscis, although they originate on the ventral surface of the head, outside of it, and only become inclosed when the edges of the upper and lower lips are fastened together. The base of the mandible always remains outside of the proboscis, inserted in a fold of the skin, and only the blade or terminal portion enters the mouth tube through the triangular open- ing at the base of the two lips. The blade of the mandible reaches to the tip of the proboscis, or may even project a little beyond the latter. It is strongly flattened dorso-ventrally and brought to a sharp edge along the two lateral margins. It is widest at the center and tapers toward both ends; it is also frequently bent at or near the center, so that the terminal portion curves in toward its fellow on the opposite side. At the tip the inner margin is cut diagonally and set with wicked teeth. Kurz distinguished three kinds of these mandible teeth; the first he called principal teeth (Hauptzihne). They are much larger and stouter than the others, they usually curve backward, and they alter- nate with the second kind, which he called intermediate teeth (Zwi- schenzihne). These are very minute, triangular in shape, and they occupy the base of the angles between the principal teeth. The vee. no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 579 third kind were called secondary teeth (Nebenzihne), and they are found in a continuous row behind the principal teeth. They are much smaller than the latter and diminish rapidly in size from in front backward. The mandibles in the genus Naobranchia (Kurz’s Oestopoda), and rarely in the males of other genera, have no interme- diate teeth, and the other two kinds are often so nearly of the same size that it is hard to distinguish them. The mandibles are operated as follows: The base being inserted in the fold of skin outside the proboscis holds the appendage rigidly in position, with its toothed tip at the opening of the proboscis, the two mandibles almost or just touching, and the two rows of teeth facing each other. The proboscis is then thrust against the skin of the host and the mar- ginal fringe is flat- tened out, laying bare the tips of the mandibles. These are pushed into the skin far enough for the teeth to get a good hold. The eS mandibles are then =. ea drawn back into SD the proboscis by & .

As the base of the mandible is pulled by this muscle the skin fold in which the mandible is inserted is turned inward like the end of a glove finger. The withdrawal of the mandibles also brings the fold of the host’s skin, in which their teeth are caught, up into the mouth opening. Here the skin is further lacerated by a sawlike motion until the blood flows freely. During retraction the mandible is also twisted through an angle of 90° upon its long axis, as was first discovered by Kurz. This brings the teeth around, so that instead of facing each other, as at first, the toothed portions of the mandibles both point in the same direction—-ventrally. This flexion, after the mandibles have been thrust into the skin of the host, gives them a better hold and keeps the wound open so that the blood will flow freely. The maxillipeds, and in some species the second antenne, are also inserted in the host’s skin and help to hold it up against the mouth tube. 580 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. The first mazillae (mz, fig. 3) are very rudimentary and palplike and contain no chitin, but are soft and flexible like the first antennae. They have been variously interpreted by different authors, the most of whom have called them palps and have connected them with the second antennae or the mandibles. But Kurz proved conclusively that they are appendages of the same rank as the antennae and man- dibles; that they have no connection with either, but are moved by an entirely independent set of muscles, and that in the majority of instances they are themselves furnished with a very respectable palp. Furthermore, it was found by the present author ' that these appendages are innervated by a separate nerve from the infra-esopha- geal ganglion, which adds the final touch to the proofs already accu- mulated. Their position is on the sides of the proboscis, close to its base and much nearer the ventral than the dorsal margin, and they do not usually reach beyond the mouth opening. Their general form is narrow and cylindrical, shghtly contracted at the base where they join the proboscis, and divided at the tip into two or three fingerlike rami, each of which terminates in a stout and acuminate soft seta. At or near the center, on the ventral surface and at the inner margin, each maxilla gives off a palp, which is usually divided at the end, like the maxilla itself, into two or three fingerlike processes, each armed with a soft seta. There is no genus in which the maxillae show definite segmentation, but they always appear one-jointed. The maxillae in the male correspond very closely with those of the female of the same species. The second mazxillae have become the principal organs of attach- ment in the present family, and accordingly we find them modified in various ways to serve this function. When they first appear in the metanauplius stage they are clawed appendages, similar in all respects to the maxillipeds. In the free-swimming or first cope- podid stage, when the larva attaches itself toits host or shortly afterwards, these second maxillae are fastened to the proximal end of the frontal filament. In the female this union of maxillae and filament becomes permanent throughout life, and the two fuse thoroughly until all that is left of the filament is the button or bulla which joins the tips of the maxillae and serves to anchor them firmly in the tissue of the host. No such union takes place in the male and his second maxillae remain clawed appendages, very similar to the maxillipeds. In the female, after the fusion of the maxillae and filament, the former lose their claws and all traces of segmentation. Even the internal muscles are entirely changed and become longitudinal bundles running the whole length of the appendage without a break. This length varies greatly in the different genera and furnishes, with 1 Proc. U. S. Nat. Mus., vol. 39, pl. 34, fig. 33. No. 2068. NORTH AMBERICAN PARASITIC COPEPODS—WILSON. 581 other coordinate differences, excellent generic characters as already noted (see p. 573). In one species, Lernaeopodina longimana, the arms, as these transformed second maxillae are called, are as slender as threads and fully three times the length of the entire body. On the other hand some species of Clavella have no arms at all; they have entirely disappeared and the attachment bulla is sessile upon the ventral surface of the body. Yet even in these species we find the remains of the maxillary muscles arranged in pairs on either side of the sessile bulla. Between these two extremes there is almost every gradation. The arms are usually separated to their tips, where they are united to the pedicel of the bulla. In the genus Clavella, however, the’arms are fused together more or less, sometimes for their entire length. When they first appear these second maxillae are on the head and in front of the maxillipeds, but during subsequent development the two usually exchange places. The second maxillae then migrate onto the first thorax segment and may move a long distance behind the other mouth parts (Clavellisa, Brianella, etc.). The bulla is composed of the hardened secretion of the frontal gland and is usually mushroom-shaped, but may be club-shaped -(Basanistes, Salmincola thymalli), button-shaped (Clavellopsis sargi, Brachiella trigle), funnel-shaped (Clavellopsis fallax), goblet-shaped (Brachiella hostilis), star-shaped (Tracheliastes stellifer), or even flattened out like a plate (Salmincola inermis). The way in which this bulla is fastened to the host has already been described. There is one thing to be added which was also noted by Kurz. The viscid secretion which fastens the bulla to the skin of the host acts as an irritant and causes the skin to fester and swell into a wall or fold, which rises up around the bulla and finally entirely envelops it. This adds greatly to the security of the attachment; in fact the only way in which the parasite can be detached is by dissecting out the bulla, which usually proves to be a difficult process. We should also notice the peculiar muscle bands which serve as second maxillae in Naobranchia, and the unique sucking disks just outside the base of the maxillipeds (see p. 662). The mazillipeds—These are clawed appendages, similar to those found in all the copepod families. They consist of a powerful basal . joint well supplied with strong muscles, which operate the terminal claw and flex it down against the inside of the basal joint. The claw is usually straight or slightly curved, and is often reinforced near the’tip by a short spine or secondary claw. The inner surface of the basal joint, against which the claw shuts, is also roughened and armed with various teeth, processes, spines, etc., to increase the firmness of the hold. In the male the claw is 1Proc. U. S. Nat. Mus., vol. 39, p. 211. 582 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. usually curved more than in the female, and in Thysanotella, if Bassett-Smith’s figure be correct, it describes three-quarters of a circle. These maxillipeds in the female have lost their function of attachment organs, and are used only for pulling the head down to the skin of the host and holding it while the parasite gets its food. In Tracheliastes even this function is lost, and it is difficult to under- stand how they can be used at all, situated as they are between the bases of the second maxillae (see plate 40, fig. 106). The muscular system.—This is extremely simplified, and is as much reduced as is possible con- sistent with retaining any power of motion. We may divide the musculature of the adult female as follows: 1. Dorsal muscles.—Along either side of the median line of the dorsal surface are two bands of longitudinal muscles, the outer band considerably wider than the inner one (fig. 4). These bands are curved length-" wise, being farther apart at the center and closer together at the ends. The four bands are each broken at the points which repre- sent the dividing lines between the different body segments, and thus furnish the best, and in some gen- era (Basanistes, Clavella, etc.) the only, evidence of segmentation. According to this evidence the~ body of the female of Achtheres is made up of a cephalothorax, which is a fusion of the head and first Fic. 4.—DORSAL MUSCLES OF ACHTHERES AM- thorax segment, and a trunk, BLOPLITIS. . . which is made up of three thorax segments, a genital segment, and a one-segmented abdomen. The inner pair of muscle bands start from a common point of attachment at about the center of the dorsal surface of the cephalothorax. They diverge until they reach its posterior margin, run approximately par- allel through the second and third thorax segments, and converge in the fourth segment, meeting again at its posterior margin. In the genital segment and in the abdomen there is but a single fused muscle band along the median line. A similar fusion takes place on the ventral surface, this time between the components of the right and left pairs. No. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 583 The outer pair of dorsal muscle bands start also from a common point of attachment in what may be called the throat of the parasite on the ventral surface of the first thorax segment, just behind the mouth parts. They run upward toward the dorsal surface and rap- idly outward, so that at the posterior border of the second segment each is outside of the inner pair. They then run backward outside of the latter and parallel with them as far as the posterior border of the genital segment, where they abruptly cease. 2. Ventral muscles.—Y our similar bands run along the ventral surface, but with these differences; they start side by side at the ante- rior border of the second thorax segment, diverge a little, then converge, and end abruptly at the poste- rior margin of the genital segment. Instead of the median pair being fused it is the two on either side of the median line which are partially fused in the fourth segment and completely fused in the genital seg- ment (fig. 5). 3. Muscles of the second maxillae.— During the cope- podid stages these append- ages are two-jointed and furnished’ with claws, and the muscles are arranged like those of other two- jointed appendages. But after fixation to the host and the subsequent fusion of the second maxillae with the attachment filament the jointing in these appendages is lost. And in place of the original musculature we now find two bands of muscles running the entire length of the appendages without a break, even though that be three times the length of the entire body (Lernaeopodina longimana). In those genera like Clavella, where the second maxillae are often lacking, leaving the attachment bulla on the ventral surface of the thorax, we still find the rudiments of a pair of longitudinal muscles, which represent the original appendages.

Similarly in those species in which the second maxillae are united throughout their entire length these longitudinal muscles remain sepa- rate and thus witness to the paired origin of the attachment organs. 4. Muscles of the other appendages.—The mandibles and first max- illae are each supplied with the usual muscles. The one attached to the base of the mandible (rm, fig. 3) is a powerful retractor, which not only draws the mandible back into the proboscis tube but also turns it sidewise, so that the toothed edge points ventrally. There may be either one or two muscles connected with the base of the first maxillae, but the amount of mo- tion they produce is very Re nn ee slight. The maxillipeds are provided with the usual muscles found in apes such two-jointed ap- pendages, those design- ed for the flexion of the terminal claw being usu- ally very powerful. The ae iia «| muscles of the first and | second antennae also 2 produce but little mo- So Ne corn aaa tion; these appendages are often very obscurely jomted and the muscu- lature then gives the most reliable informa- tion as to the number of joints. In some genera (Basanistes, etc.) the second antennae are ex- ceptionally developed and are furnished with the musculature neces- sary to enable them to function as organs of prehension. The mouth tube is also furnished with muscles by means of which it can be directed and held against the skin of the host or withdrawn at pleasure. 5. Special muscles.—In addition to the muscles already enumerated there are others which serve specific purposes and which consequently deserve particalar notice. The first of these may be termed the circu- latory muscles, since it is through their contraction and relaxation that the meager circulation in these parasites is maintained. There are three pairs of them, an anterior pair in the third thorax segment, a median pair in the fourth segment, and a posterior pair in the fourth U partir v Fic. 6.—CIRCULATORY MUSCLES OF ACHTHERES AMBLOPLITIS. a, ANTERIOR; ™, MEDIAN; P, POSTERIOR. no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 585 and fifth segments. The anterior pair (a, fig. 6) are short and cylin- drical and each originates in the groove separating the second and third thorax segments on the dorsal surface about half way from the lateral margin to the midline. Jt then runs diagonally inward and backward and is inserted in the side of the digestive tube, a little above the center. The median pair (m) are strongly flattened dorso-ventrally; each originates at the center of the lateral margin of the fourth segment, extends directly inward, and is inserted in the wall of the stomach; it is narrow at its origin but widens out greatly at its insertion. The posterior pair (p) are cylindrical again; each originates on the dorsal Fic. 7.—THE MALE OF CLAVELLISA CORDATA. aN’ AND an’’, ANTENNAL MUSCLES; md, MANDIBLE MUSCLE; mx’ and mz’’, MAXILLARY MUSCLES; ™ztp, MUSCLES OF THE MAXILLIPED. wall of the genital segment, extends diagonally forward and inward, fuses with its fellow from the opposite side, and is inserted in the cen- ter of the dorsal wall of the intestine. The anterior and posterior pairs pull the digestive tube backward and forward, while the median pair pull it to the right or left. Another pair of special muscles may be called the ejaculatory muscles; they are situated on the dorsal surface of the semen recep- tacle in the genital segment (em, fig. 8). Each extends from the thickened margin of the external opening of the oviduct diagonally inward and backward to the center of the dorsal surface of the sperm receptacle. A contraction of these muscles aids in forcing the eggs out into the external sacks, and may at the same time help to dis- charge the contents of the sperm receptacle. 6. The musculature of the male——In those males in which the cephalothorax and trunk are either in the same line (Achtheres, etc.) or somewhat flexed without any fusion (Brachiella, etc.) the general 586 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47, scheme of musculature is similar to that of the female. But where there is not only flexion but also complete fusion (Clavella, Clavellisa, etc.) the musculature is entirely changed. We no longer find any dorsal and ventral body muscles, or any special respiratory muscles, but all the movements of the body are accomplished by means of muscles connected with the appendages. The male of Olavellisa may be taken as an example (fig. 7). The muscles of the left side only are given in the figure, and it is to be understood that each is duplicated on the right side. It will be noted that there are single muscle strands connected with the first and second antennae (an’, an’’), larger and more powerful single muscles connected with the first maxillae (mz’) and the mandi- bles (md), while there are three stout muscles attached to each sec- ond maxilla (mz’’) and maxilliped (mxp). Each of these muscles is inserted in the base of the append- age to which it belongs and runs diagonally into the body to its origin, somewhere on the dorsal or Fic. 8.—DoRSAL VIEW OF EJACULATORY MUS- lateral walls. fee RO ee, Allthe necessary iaotions +n the male are accomplished by these ap- pendage muscles. In these pigmy males, therefore, the last vestige of segmentation, namely, the interrupted longitudinal muscle bands, has completely disappeared. RESPIRATION. There is in this family nothing which resembles, or functions as, a respiratory organ; there is not even the opening and closing of the anus and rectum (anal respiration) so prevalent among the free- swimming forms and in the Caligidae and Ergasilidae. In the female there are no oblique muscles attached to the sides of the rectum, and in the male there is no anal opening, so that such a method of respiration is impossible in both sexes. Apparently the only means of aérating the blood is through the body walls, which are comparatively thin. Furthermore the demands for aération have been reduced to a minimum in these parasites, who have lost all freedom of motion, whose food is very easy to digest, and whose circulation is extremely crude. CIRCULATION. There is no heart nor any blood vessels in the Lernaeopodidae; there are not even any lacunae through which the blood might flow. The body is virtually a bag, in the cavity of which are suspended the various organs, while the spaces around them are entirely free, and No. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 587 every part is in direct communication with every other part. The blood moves about freely through these open spaces and a sort of circulation is accomplished by a rhythmic contraction of the three pairs of special muscles already described (see p. 584). The muscles in each pair contract alternately and pull the intestine away from the midline, now toward the right side and now toward the left, or forwards and backwards. When the intestine is pulled to the right the blood on that side of the body is pushed precipitately forward into the head. At the same time on the left side of the body the blood streams backward from the head to fill up the space formerly occu- pied by the intestine. These motions are reversed when the intestine is pulled to the left, and this backward and forward streaming con- stitutes all the circulation. The strong peristaltic movements of the stomach and intestine help to push the blood along if it lies in contact with the wall of the digestive tract. We have used the term blood here, but of course it can bear that name only by courtesy. It is not really blood like that found in the Argulidae, Caligidae, and Chondracanthidae, but is simply the liquid which fills the body cavity. It has no corpuscles but may serve to distribute the oxygen absorbed through the body walls. In the male there is not even this apology for a circulation, and in all those which have been examined there has never been observed a streaming of the liquid contents of the body in any direction. The body of the male is reduced to such a small size that probably enough oxygen can be obtained by direct absorption through the body walls. THE DIGESTIVE SYSTEM. In the present family this consists of a mouth, an esophagus, a stomach, and an intestine. The mouth-tube is turned forward and is the most anterior part of the body, with the mouth-opening at its tip. The structure of the mouth and the mode of filling it with blood have already been described (see p. 577). There are no glands connected with the mouth and the only use it serves is as a funnel to guide the blood into the esophagus, which is slender and thread-like and almost straight (fig. 122). It passes abruptly into the enlarged stomach, a thick sphincter muscle being found at the point of junction. This latter is in the head and about on a level with the bases of the maxillipeds, even in those genera (Clavella, Clavellisa, etc.) which have very long necks. In such genera most of the stomach, and by far the most important part, is located in the neck. The stomach passes so insensibly into the intestine that it is impossible to distinguish any point of separa- tion. Both stomach and intestine possess thick walls made up of an outer serous membrane, a median muscular layer, and an inner 588 PROCBEDINGS OF THE NATIONAL MUSEUM. vou. 47, glandular layer. The latter contains many modified cells, which are filled with a digestive fluid, and thus take the place of digestive glands. In the long-necked genera that portion of the stomach, if any, which enters the trunk is narrowed and flattened and so crowded by the reproductive organs that it functions only as an intestine. THE EXCRETORY SYSTEM. In the Lernaeopodidae the excretory system is made up of two pairs of glands. The maxillipedal pair are on the dorsal side of the body, behind the bases of the maxillipeds. Each starts at three different centers, one median and two lateral, which increase in size and grad- ually fuse together. A spirally convoluted duct leads to the base of the maxilliped where it opens to the surface. The maxillary pair are situated at the bases of the second maxillae; a straight duct leads from each gland outward and opens on the inner surface of the maxilla (fig. 141). In those genera (Clavella, Clavellisa, etc.) where the second maxillae have disappeared and the bulla is on the ventral surface of the trunk, the maxillary glands have migrated into the trunk and can be found on either side of the bulla. This is also the case in Naobranchia where the second maxillae are present but are so modified that they can not contain the glands (p. 661). In many species also, of various genera, the second maxillae are so slender and their inner cavity is so filled with the longitudinal muscles that there is little room left for the glands. In such species there is often a swelling on the outer surface of-the maxilla near its base, and in this swelling is located the gland (fig. 221). Or the swelling may be on the side of the neck near the base of the second maxillae (fig. 109.) THE NERVOUS SYSTEM. The nervous system’ consists of a very large infra-esophageal ganglion and an equally small supra-esophageal ganglion (fig. 122). From the anterior end of the latter two pairs of nerves are given off, one of which goes to the first antennae and frontal margin, while the other larger pair supply the second antennae and upper lip. From the posterior end a third pair of nerves run backward along the anterior walls of the stomach, the dorsal portion of the head, the frontal gland, and the maxillipedal gland. From the anterior end of the infra-esophageal gland a pair of nerves run forward to the base of the lower lip and send a branch to the mandibles. From the ventral surface of this ganglion a slender nerve goes to the first maxilla on either side, another to the second max- illa, and from the postero-ventral corner a larger nerve runs to the maxilliped. Just in front of this last nerve a delicate nerve thread 1 Good figures of the nervous system of both sexes were published in these Proceedings—vol. 39, plate 34. no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 589 runs diagonally to the sides of the maxilli-pedal and maxillary glands. At the posterior corner of the ganglion a slender nerve extends back- ward along the ventral walls of the stomach and close to its fellow from the other side. These nerves show no ganglionic swellings and no ganglion cells. The nervous system is thus practically concentrated in the infra-esophageal ganglion. THE REPRODUCTIVE ORGANS. The reproductive system in the female consists of paired ovaries and oviducts, an unpaired sperm receptacle, and paired cement glands. In the male it consists of paired testes and vasa deferentia, and paired spermatophore receptacles. The ovaries and testes lie in what may be termed the small of the back, between the stomach and the dorsal body wall. From the posterior ends are given off the oviducts and vasa deferentia which run around the stomach to the ventral surface, and then backward to the openings in the sides of the genital segment. In both sexes these ducts become so convoluted and swollen at maturity that they fill the entire cavity on either side of the digestive tract, which is flattened laterally into a mere slit. The sperm receptacle in the female lies in the posterior portion of the trunk, sometimes dorsal and sometimes ventral to the mtestine. In those genera (Achtheres, etc.) which have an abdomen the recep- tacle is dorsal and consists of a bag nearly twice as long as wide, placed transversely in the trunk and flattened dorso-ventrally. Each end of the bag is prolonged at the anterior corner into a slender tube which runs outward to the oviduct and opens into the latter just inside of its external opening; at the posterior corner into a canal, the vagina, which leads diagonally backward and inward to the posterior margin of the abdomen, where it opens to the exterior alongside the midline. In those genera (Clavella, etc.) which have no abdomen the sperm receptacle is ventral to the intestine, is not as long as in Ach- theres, and the vaginae are usually more or less fused. They run back through the genital process and open at its tip, either closely side by side or, if fused, in one common opening. When the spermatophores are fastened by the male upon the abdomen or genital process of the female their tubes enter these external openings (vulvae). And the spermatozoa which they contain are discharged through the vulvae and vaginae into the receptacle. In the present family there is no crossing of the tubes of the spermato- phores, as in the Caligidae, but each spermatophore empties into the vagina on its own side of the body (fig. 8, p. 586). Even in those genera where the vaginae are fused and have a common vulva the spermatophore tubes are still uncrossed. 590 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. When once filled the sperm receptacle holds enough to fertilize all the eggs the female will ever lay. Whenever an egg is sufficiently matured it passes down the oviduct and out into the external cases. As it passes the opening of the sperm tube it is fertilized, and this individual fertilization is responsible for the remarkably small num- ber of eggs that fail to develop. The cement glands are very large and in Achtheres fill the entire sides of the thorax segments in front of the genital segment. Each is crescent-shaped, its outer convex surface fitting snugly inside the lateral body wall, while its inner surface is nearly straight. It consists of three parts, separated by well-defined constrictions. The anterior, terminal portion (f) is about one-quarter of the entire length and is filled with a fine-grained matrix out of which is formed the cement substance. This is the real glan- dular portion where secretion is carried on. The central half (c) is a little broader than the terminal portion and is somewhat flattened dorso-ventrally; its wall is trans- versely striated and must contain muscle fibers since it is more or less contractile. It is evidently used for the storage of the cement sub- stance until the eggs have fully ripened (fig. 9). Fig, 9.—CEMENT GLANDS OF ACHTHERES AM- The posterior basal portion (6) BLOPLITIS. 6, BASAL PORTIONS; ¢, CENTRAL; forms the duct or tube through ee Rak which the cement substance passes out into the oviduct. It has a sharp curve or bend on its inner margin around which the tube passes and which acts as a sort of valve to regulate the flow. The cement glands of all the other genera in which they have been observed are similar to those of Achtheres. In the male the vasa deferentia lead around the side of the stomach to the ventral surface, swing back again to the dorsal surface, run diagonally backward to the center of the lateral surface, turn a little toward the dorsal surface, and finally pass diagonally backward to the opening on the ventral surface of the genital segment. The swollen anterior portion of these convolutions is a combination of cement gland and vas deferens, the fine-grained gland cells secreting the viscid substance which composes the covering of the spermato- phore. The posterior portion in the adult male is enlarged into a receptacle within which the spermatophores are gradually matured and filled with spermatozoa (compare fig. 198). no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 591 ONTOGENY. The complete life history of Achtheres ambloplitis has already been published.' Fasten has also given us an account? of the free swimming larva of Salmincola edwards. Some of these copepodid larvae, admirably mounted, were loaned to the present author for study and comparison, and have proved of great value. It only remains, therefore, to restate the life history very briefly, and to compare the larvae of the two genera above named with those of Clavella, the material for which is here presented for the first time. Inside the ovary are many long filaments, which are connected with the older oocytes and whose terminal cells develop successively one after the other. In Clavella uncinata (fig. 10) these filaments are given off dorsally and pass down ventrally into the convolutions of the oviduct, where the end cells can be seen in various stages of development. These filaments are longer and less convoluted in Olavella and Clavellisa (fig. 11) than in Achtheres or Naobranchia (fig. 12). They stain readily and in double-stained sections always show a dark purple color. A vi- Fig. 10.—Eae ese AND DEVELOPING EGG 2 ee IN CLAVELLA UNCINATA. telline membrane is visible around the end cell, even before it separates from the filament. Inside of this*membrane the entire substance of the egg is made up of yolk globules evenly distributed through a fine matrix of protoplasm. Seat- tered about are numerous large vacuoles of different sizes, those nearest the periphery being usually the smallest. As the eggs pass down the oviduct they are each fertilized at the opening of the sperm tube, and are covered with a layer of the cement substance before they pass out into the external sacks. In the latter they segment, and the larvae develop through the nauplius and metanauplius stages before hatching. Segmentation is entirely superficial, the cytoplasm sepa- rating from the yolk, migrating to the surface and there forming blastoderm cells around nuclear centers. The yolk remaining inside the egg and afterwards inside the embryo serves to nourish the latter not only through the nauplius and metanauplius stages but also through the free swimming copepodid stage. Since neither the nau- plius nor the metanauplius can escape from the egg, their unfolding is necessarily condensed. Usually the three nauplius appendages de- velop and serve their temporary function before the other appendages 1 Proc. U. S. Nat.

But here in the Lernaeopodidae the mouth parts and the first two pairs of swimming legs appear simultaneously with the nauplius appendages, and they all develop together. The early larval stages are thus so thoroughly fused as to become virtually one single period, and the peculiarities which characterize the different stages overlap one another, several some- times being present at the.same time.

NORTH AMERICAN PARASITIC COPEPODS—WILSON. 593 First copepodid or free-swimming stage-—Body elongated, flattened dorso-ventrally and made up of a cephalothorax, three free thorax segments, and a fused gen- ital segment and abdomen, carrying the anal laminae. The cephalothorax is a more (Clavella) -or less (Ach- theres and Salmincola) com- plete fusion of the head and first thorax segment. In the latter genera the separation of the two is indicated by notches on the lateral mar- gins and by a dorsal groove; in the former genus these do not appear. The shape of ' this cephalothorax is ellipti- cal in Salmincola, ovate in Clavella, and elliptical or sub- quadrilateral in Achtheres. A characteristic copepod eye is found at about the center of the cephalothorax in Clavella cance? and Salmincola. The eye in (yr 1\\ Achtheres is so rudimentary 0.2mm, Hf \X that it can not be seen except 4 . 1 in sections. In the front of Ji the head, close to the dorsal Lp \ surface, lies the attachment filament which is characteris- tic of this family. It con- sists of a long cylindrical rod, enlarged at either end; the A j i enlargement of the distal end / is in the shape of a mushroom or umbrella, and is the part that sticks to the flesh of the Fic. 13.—COPEPODID LARVA OF CLAVELLA UNCINATA. host, and becomes the bulla or attachment organ of the adult parasite. The cylindrical rod is folded in a single loop in Salmincola, coiled like a rope in Achtheres, and wound into a tight spiral in Clavella (fig. 13). The first thorax segment is two-thirds as large as the head, is fused with the latter, and tapers posteriorly, terminating in two large lobes which correspond to the posterior lobes of the carapace in the Caligidae. The second (first free) thorax segment is much larger than the seg- 34843 °—Proc.N.M.vol.47—14——38 594 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. ments which follow it in Achtheres and Salmincola, but is the same size or a trifle narrower in Clavella. The third and fourth segments are about the same size and length in all the genera, but their relative size compared with the cephalothorax or with the second segment varies greatly. In general they are very narrow in Achtheres and Salmincola and very wide in Clavella. The last segment is a fusion of the posterior portion of the thorax and the abdomen, and it carries the anal laminae, which are variously armed with setae in the different genera. The first antennae are four-jointed and extend directly out- ward at right angles to the body axis in Salmincola and Achtheres; in Clavella they ap- parently have fewer joints and are turned backward along the b sides of the carapace. d The second antennae are biramose, the exo- pod one-jointed and tipped with a single eee seta, the endopod two- : jointed and ending in Fia. 14.—CopEPoDID LARVA OF CLAVELLA UNCINATA. @, MANDIBLE; a pow erful hook ed b, FIRST MAXILLA; €, SECOND MAXILLA; d, MAXILLIPED. claw. The mouth- tube projects downward and forward from between the bases of the second antennae. It is made up of an upper and under lip, the lat- ter grooved and fluted, overlapping the edges of the upper lip, and consisting of two halves, which are often not entirely fused. The mandibles are outside the base of the mouth-tube, one-jointed and tipped with short setae; the first maxillae are also uniramose but two-jointed and tipped with longer setae; the second maxillae are stout, two-jointed, and tipped with a long and slender claw, bent into a half circle; the maxillipeds are also stout, three-jointed, and tipped with a stouter and straighter claw (fig. 14). Swimming legs biramose, the basal joints broad and laminate, and furnished with powerful muscles, the rami small, one-jointed, and armed with long plumose setae (fig. 15). : As soon as this copepodid larva escapes from the egg it begins an active search for a host. By means of its two pairs of swimming legs it moves about actively in a more or less spiral path.' This movement is kept up for 24 to 48 hours, and then relaxes, the larva becoming so wearied that it can scarcely move at all. Conse- quently it must find a host within this time or perish; if it is fortu- nate enough to come in contact with the right kind of fish it fastens 1 Fasten, Journ. Animal Behavior, vol. 3, 1913, p. 43. No. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 595 itself at once to it. It is a general rule that every species of fish has its own peculiar parasites, and hence the latter must have seme means . of selecting the right host. It is also true that the more fixed the parasite becomes and the less capable it is of moving about, the ‘more exclusively is it confined to one species of fish. It is only the free-swimming forms like Argulus and some of the Caligidae that have a long list of hosts. Eyesight probably has very little to do with the selection of the particular host, especially in the present family, where the eyes are so rudimentary as to be practically useless. Fasten’s experiments with Sal- mincola edwardsvi, together with re- peated observations by the present author, would indicate that the choice is made by some chemical means, smell or taste, or a combina- tion of the two. Actual attachment is accomplished by bringing the frontal margin of the head in con- Qe tact with the skin, fin, or gill of the host. The mushroom end of the at- tachment filament then sticks fast, and the filament is withdrawn from the head. In Salmincola, according to Fasten, the larva remains a short time attached by the frontal filament; in the other genera such an attach- ment has not yet been observed. But in any case this attachment lasts only a short time; the proximal Fic. 15.—Firsr (upper) AND SECOND swIM- bud-otthe filament is grasped by the oc Oo Cre Mars or second maxillae and detached from the frontal margin of the head. The maxilla and filament are then thoroughly fused, and remain as the so-called arms or permanent attachment organs of the adults of this family of parasites. There is always an absorption of the filament, and there may be also an absorp- tion of the maxillae until all that is left of the original apparatus is the distal mushroom enlargement of the filament, the bulla, buried in the flesh of the host. Many species of Clavella show such a condition, the bulla being fastened directly to the ventral surface of the trunk. On the other hand, after the filament has been absorbed the arms sometimes lengthen until they may become two or three times the length of the entire body, as in Lernaeopodina. The male does not become permanently attached in this way, but retains his hold on the filament for a short time only and then lets 596 PROCEEDINGS OF THE NATIONAL MUSEUM. you. 47. go and clings to the body of the female for the rest of his life. Sub- sequent to attachment the changes which take place in the copepod are chiefly concerned with the development of the reproductive organs. In the fixed female the legs, the segmentation of the body, and frequently the anal laminae disappear. At the same time the trunk or so-called genital segment increases through the develop- ment of the convolutions of the oviducts and becomes relatively as well as actually much larger than before, and finally the external egg sacks are formed, which may be regarded as the completion of the life cycle. The male does not increase much in size, but remains a pygmy; he usually loses the two pairs of swimming legs, but retains, in part at least, the body segmentation. The maturimg of the spermato- phores and their subsequent attachment to the genital process of the female marks the completion of his life cycle, and he does not probably live very long afterwards. SYSTEMATIC. Historical—tIn the first edition (1735) of his Systema Naturae Linnaeus placed all the crustaceans among the wingless insects under three genera. It is very doubtful if any member of the present family was included in this first edition. But later in the second edition of the Fauna Suecica (1761) he described Lernaea salmonea, which is really a Lernaeopod and probably the oldest member of the family, and which he located among the mollusks. Having thus begun under the genus Lernaea, the present family was for a long time included with the Lernaeidae. On account of their degenerate form they were not placed with the crustacea by any of the earlier zoologists. Lamarck, after locating them among the mollusks (1801) and the annelids (1809) went so far as to create a separate group to receive them (1812) which he called the Epizoaria and placed between the worms and the insects. In his Handbuches der wirbellosen Thiere (1816) he writes that he had found Lerneans which showed a transition from insects to worms so that the Epizoaria could be regarded only as a-provisional or temporary class. Bose, also following Linnaeus, placed them among the mollusks (Historia Vermium, n. d.), but contended that they were closely related to the intestinal worms. Oken, in his Lehrbuch der Natur- geschichte (1815-16), included some of the Lernaeopodidae in two different places. First he placed among the worms (pp. 182-184), between Echinorhynchus and Hamularia, the genera Philline, Schis- turus, and Lernaea. Second as a separate group, the Armwiirmer (pp. 357-359), between Asterias and Gordius, he placed not only Axine, Clavella, Pennella, and Lernaea, but also Dichelesthium, Caligus, no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. boy and Argulus. But while locating them thus wrongly, he at the same time pointed out their close relationship to the Entomostraca, and thus made a notable advance over his predecessors. De Blainville published in the Bulletin des Sciences, Paris, 1816, a new classification of the animal kingdom in which he placed the Lernaeopodidae with other copepod parasites, in a subclass Epizoaires under the class Tetradecapods and the group Articulates. Later he made a special study of the Lernaeidae and gave (Journal de Physique, 1822) the first good account of their anatomy. He divided the family into a large number of new genera, which he arranged according to their morphol- ogy and the nearness with which they approached Caligus. The seventh of these was the new genus Lernaeopoda, the type of the present family. Latreille in Cuvier’s Régne Animal keeps the Lernaeans among the intestinal worms even as late as 1830. He admits that other authors have claimed that these parasites are crustacea, as is shown by the males, but he adds, ‘‘pour consacrer cette opinion, il foudrait pouvoir rétrouver ces males” (vol. 3, p. 256). He introduces with Oken’s Clavella the new genera Anchorella and Brachiella, which belong to the Lernaeopodidae and are of course ascribed to Cuvier. In 1831 he published a Cours d’Entomologie in his own name wherein he described the Siphonostoma as an order of the section Edentata of the class Crustacea. He calls the second family of this order Lernaciformes, but does not include in it any of the Lernaeidae, thus failing to recognize their relationship with the Siphonostomata and other crustacea. Desmarest, in his monograph of the crustacea (1825), after showing that the Lernaeidae belong with the Caligidae among the crustacea, finally places them under the Poecilopoda, an order of the subclass Entomostraca. Wiegmann, in his Grundriss der Zoologie (1823), was the first to give the Lernaeidae their proper position, partly agreeing with Blainville, partly with Desmarest, and partly with other German investigators like Nitzoch and Leuckart. He was fol- lowed by Nordmann (1832) and Burmeister (1833), who confirmed the position assigned. to the Lernaeidae, and added many of the facts necessary to confirm their views. Nordmann established the new genera Achtheres, Basanistes, and Tracheliastes, and described new species in several of the old genera. Burmeister at the close of his paper adds some general considerations in which he gives us the first division of the group Siphonostoma into five families. The second of these, the Lernaeoda, corresponded almost exactly with the modern family Lernaeopodidae, but included, beside the true Lernaeopod genera, Chondracanthus and Lernanthropus. Milne Edwards was thus furnished with a large amount of necessary data which enabled him in his great work, Histoire Naturelle des Crustacés (1840), to perfect the classification of the parasitic cope- 598 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. pods in many particulars. He recognized two orders, the Siphonos- toma, including the Argulidae, the Caligidae, the Pandaridae, the Dichelestiidae, and the Ergasilidae, and for the second order the Lernaeidae, including the Chondracanthidae, the new family, the Lernaeopodidae, and the Lernaeoceridae. The family was thus first introduced by Milne Edwards, and since that introduction the only changes in it have been the addition or removal of various genera. Family LERNAEOPODIDAE Milne Edwards. Family characters of female ——A fixed parasite; head usually sepa- rated from the thorax, often borne on a long neck; trunk usually unsegmented, with or without posterior processes; abdomen and anal laminae often lacking; first antennae small and with few joints; second antennae biramose, flattened laterally, not prehensile; upper and under lips prolonged into a sucking tube fringed with hairs; mandibles toothed; first maxillae rudimentary, palplike; second maxillae modified into attachment organs, usually joined at the distal end and furnished with a bulla; maxillipeds of the usual pre- hensile form, tipped with claws; no swimming legs; egg strings large, multiseriate. Male.—A pigmy clinging to the body of the female but free to move about; head usually separated from the trunk, the latter more ‘often segmented than in the female; anal laminae usually present; first maxillae similar to those of female; second maxillae and maxilli- peds large and powerful, and furnished with prehensile claws; first two pairs of swimming legs sometimes present in the adult (genus Achtheres), but degenerate and useless. Remarks.—The different investigators have adopted very different methods of classification in dealing with this family. Burmeister (1833) used the structure and position of the attachment organs (Haftorganen) as the basis of the first division, and the length and shape of the cephalothorax as the basis of the second division. Milne Edwards (1840) used the same basis for his first division, but for the second one he introduced the relative position of the second maxillae and maxillipeds.1_ Baird (1850) used the structure and fusion of the second maxillae for his first and only division, which is really a generic one, since he included in the family simply the two genera Lernaecopoda and Anchorella. Heller (1865) based his first division on the presence or absence of maxillipeds, his second on the structure of the second maxillae, and his third on the form of the cephalothorax. Gerstaecker (1881) used the length and thickness of the cephalothorax for his first division, the separation or fusion of the neck and body for 1 He called them first and second maxillipeds. no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 599 the second division, and the structure of the attachment organs for the third division. Since Gerstaecker there has been no serious attempt at a revision of the classification of this family, though valuable suggestions have been made by Neresheimer (1909) and others. The following scheme of classification is a combination of all these which have preceded it, with such additions as more recent investi- gations demand. The most important of these additions and the one thing which can give the present scheme any credit, if indeed it can claim such, is the use of the male. The males are less degenerate than the females and the only reason why they have not hitherto been employed by systematists has been the fact that so few of them have been known. Neatly every investigator has called attention to the desirability of the male as a basis of generic distinction. Some have plainly stated that the ultimate decision in every question of generic validity must rest with the male. This being appreciated even by those who lacked the facts necessary to use it, it follows that type distinctions among the males ought: to possess superior value in distinguishing the genera. Accordingly, so far as has been pos- sible in the following classification, each genus presents a certain type of male, which is fully described and figured in the genus diag- nosis. To facilibate comparison these 17 male types are shown side by side in plates 25 to 28, the scale mark by the side of each repre- senting one-tenth of a millimeter. TABLE OF GENERA. 1.

Synonyms.—The mouth parts being difficult to discern while the swimming legs are entirely lacking, the old investigators were com- pelled to depend largely upon the general form, the external appear- ance, and the egg strings. These features are changeable enough at their best, but when we reflect that practically every specimen described by those investigators had been preserved in strong alcohol we wonder that they located so many of them correctly. The alcohol warps and distorts the soft and unresisting tissues, wrinkles the skin, changes or bleaches out the color, and shrinks the bodies. In view of these facts it is not surprising that the same animal in three or four different kinds of preservation has served as the type of as many distinct species or even genera. In consequence there are very few of the genera which do not have at least one synonym, while some of them have as many as four. The following is a list of the synonyms as at present recognized: Pediculus—Baird in his British Entomostraca says: ‘‘the first notice taken of any species appertaining to the genus [Lernaeopoda] was by Gisler in 1751, who, in the twelfth volume of the ‘Acta Suecica,’ describes and figures a species of Lernea found by him on the salmon, and which he called ‘Pediculus salmonis or Lax-lusen’”’. 'There is no twelfth volume, 1751, of the Acta Suecica, but in vol. 12, 1751, of Kongl. Svenska Vetenskaps Academiens Handlingar, p. 185, Nils Gissler described ‘‘Lax-lusen,” but did not mention Pediculus. Hence the name must be dropped, especially as it was afterwards used by Linnaeus for a genus of Epizoa. 602 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47. | Schisturus.—This name was applied by Rudolphi in 1809 to a genus of worms, and by Oken in 1815 to a single species of the genus Cla- vella. In this latter use it becomes a synonym. Entomoda.—Applied by Lamarck in 1818 to the genus Lernaeopoda; but as the type or first species named by Lamarck under his new genus was Ef. cornuta, which belongs to the genus Chondracanthus, established in 1811, it is evident that the name can not be used for a Lernaeopod. Anchorella.—Proposed by Cuvier in 1830 for a single Lernaean which he wished to establish as a new genus, and afterwards applied by other authors to the entire genus Clavella, excluding the latter name. But the name Clavella had been published by Oken in 1815 and hence Anchorella is either a distinct genus or becomes a syno- nym (see p. 667). Lernaeomyzon.—Proposed by Blainville in 1822 for this same genus Clavella, but the latter had seven years’ precedence. Hessia.—In 1870 Edouard van Beneden published a paper‘ en- titled “Developpement des genres Anchorella, Lernaeopoda, Brachiella, et Hessia.”’ No description of this last-mentioned genus is given, nor any figures except of the eggs and one larval stage. Beneden says of it that it approaches on the one side Anchorella, which it resembles in all the phenomena of development, while on the other hand it is like certain of the Chondracanthidae in its external appearance; that it is a very common parasite along the coast of Brittany in the gill cavity of Trigla lineata. It may be the same species that Richiardi afterwards designated as Anchorella carusi. But he also has given us no description or figures; hence both designations become mere names until something further is known about them. Cestopoda.—Kurz in his admirable paper on the Lernaeopodidae (1877) described and figured a new genus and species which he des- ignated as Cestopoda amplectens. But 14 years before Hesse had described a new genus and species which he called Naobranchia cygni- formis. The two genera are identical, although the species are dis- tinct, and hence Kurz’s name must become a synonym of that given by Hesse.’ Stylophorus.—In 1878 Hesse published the description and figures of another new genus and species which he called Stylophorus hippo- cephalus. But on examination this proves to be the same genus that Kréyer had designated as Charopinus in 1863. Hence Hesse’s name must become a synonym of Kréyer’s. Thynnicola.—Miculicich in 1904 described what he thought to be a new genus and species under the name Thynnicola ziegleri, but which 1Bull. Acad. Roy. Belgique, ser. 2, Vol. 29, p. 223. 2 Annales des Sciences Naturelles, ser. 4, vol. 20, p. 101, pl. 1. no. 2063. NORTH AMERICAN PARASITIC COPEPODS—WILSON. 603 proved to be the same that Cuvier had named Brachiella thynni. The former thus becomes a synonym of the latter name. LERNAEHEOPODINAH, new subfamily. Subfamily characters of Female—Cephalothorax shorter than the arms, and in line with the body or bent forward at an angle; trunk plump, sometimes with, sometimes without, posterior processes, but _ often showing more or less distinct segmentation; a genital process in some genera but no anal laminae; second maxillae outside of maxilli- peds and the two close behind the base of the mouth tube; the maxillae united only at the tips, sometimes entirely separate; bulla, when present, of the ordinary type; egg strings usually short and plump. Male.—Cephalothorax separated by a well-marked groove from the body, which is often segmented; anal laminae present and usually directed backward; second antennae biramose and armed with a claw. SALMINCOLA, new genus. Generic Characters of Female.—Cephalothorax short, stout, and inclined at an angle to the body axis; separated from the trunk by a groove, but with no definite waist; no dorsal carapace; trunk short and stout, often flattened dorso-ventrally, with no signs of seg- mentation; no abdomen, anal laminae, or posterior processes; a small transparent genital process is present in the young female and often in the adult. First antennae indistinctly three-jomted, usually showing no segmentation; second antennae biramose, both rami one- jointed, the endopod larger than the exopod; first maxillae tipped with three spines and without a palp; second maxillae short and stout, joined at the tip by a button or mushroom-shaped bulla, often joined also at the base around the back of the thorax, forming a pair of ‘‘shoulders;’ maxillipeds with a stout basal jomt and a slender terminal claw; egg strings usually long and slender, eggs small and numerous. Generic characters of male.—Size small (0.50 mm.); cephalothorax about the same length as the trunk, the two bent into the form of a semicircle; no dorsal carapace; trunk a little stouter than the ceph- alothorax and indistinctly segmented, with a pair of short anal laminae curved dorsally; no abdomen; first antennae three-jointed; second antennae biramose, the exopod (ventral ramus) uncinate; second maxillae and maxillipeds each three-jointed, attached to the concave margin of the semicircle at the center, their tips reaching the same level as the tips of the antennae and the anal laminae; maxillipeds stouter than the second maxillae and attached inside the bases of the latter. 604 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47. | i Type.—Salmincola salmonea (Lernaea salmonea Gissler). (Salmincola, Salmo, the host family and incola, a dweller.) Remarks.—This new genus differs from Lernaeopoda in the absence of a dorsal carapace on the cephalothorax, in the fact that the first thorax segments are not differentiated, in the absence of posterior processes and a palp on the first maxillae, and in the presence of a genital process. From Lernaeopodina it may be distinguished by the absence of a dorsal carapace, posterior processes, and the palp on the first maxillae, by the presence of a genital process, and by the structure of the maxillipeds.
