BY F. C. HOTTES. The summers of 1931 and 1932 offered exceptional oppor- tunities to collect aphids on the Western Slope of Colorado, a section of the state not as thoroughly worked by Professors Gillette and Palmer as that more conveniently located for them near Fort Collins, on the eastern side of the mountains. As a result of the two seasons work the new species and hitherto undescribed forms of Aphiidae are here described. Most of the forms described here were collected between Skyway (a summer post-office and supply store, located on the shore of Mesa Lake), and the top of Grand Mesa (a volcanic plateau of some 10,000 feet altitude), upon the top of which four of the species described here were collected. In this region spring comes late and fall puts in its appearance unmistakably early so that the full cycle of events in the family life of an aphid species must of necessity be crowded into two short months. I would gratefully acknowledge the opinions of Professors Gillette and Palmer and Dr. P. W. Mason to whom certain of these species were sent for study before being definitely con- sidered as new. In this paper I have chosen to use the generic terms Dactynotus .and Adactynus proposed by Rafinesque for the generic terms Macrosyphum and Myzus, and I shall continue to do so until the Zoological Congress rules otherwise. Cinara fornacula Hotites. STEM MOTHER. Size and general color.—Average length from vertex to tip of anal plate, 4.49. Entire body slightly pruinose. Head somewhat yellowish or light dusky brown with a rather conspicuous dark median line. Thorax and 1—Proc. Bio. Soc, WasuH., VoL. 46, 1933, (1) 2 Proceedings of the Biological Society of Washington. abdomen light pea green. Cornicles concolorous with abdomen. Cauda slightly dusky. Im mounted specimens small browned wax pore-plates may be seen on the dorsum of the abdomen and thorax. The first antennal segment is concolorous with head at the base but is lighter toward its distal end; the second and third antennal segments are light yellowish in color. The third segment may occasionally be light dusky toward its apex. Fourth, fifth, and sixth antennal segments light dusky with their apical ends darker; the sixth antennal segment is considerably darker than the other segments. Eyes dark brown. Beak with last three segments dark brown, remaining segments considerably lighter in color, apical portion of long segment more or less mottled, or entirely brown. Coxae and femora of all legs light yellowish brown (femora darker towards apex). Tibiae light yellowish-brown with apical portions brown. Tarsi dusky brown. Head and appendages.—Average width of head across eyes, .90. Antennal segments with the following comparative lengths: I[I—.57 to .67, average .62; IV—.20 to .24, average .23; V—.24 to .29, average .27; VI—.16 to .20, average .18 plus .04. Secondary sensoria confined to apical half of fifth antennal segment, numbering from 0 to 2, usually 1. Primary sensorium on sixth antennal segment large and rarely with more than three widely scattered marginal sensoria. Hairs on third antennal segment brown; about one-fifth longer than width of segment, considerably longer than this on fourth and fifth antennal segments. The hair on the antennae are fairly straight and leave the segments at an angle of approximately 45°. For the genus, they are comparatively few in number. Compound eyes with ocular tubercles. Beak long, reaching beyond metathoracic coxae. Thorax and appendages.—Lateral and dorsal portion of thorax with approximately twenty-four wax pore-plates arranged in groups of two, in four, more or less irregular rows, two more or less lateral and two dorsal. All femora with a row of sensoria on their posterior surfaces. Tibiae comparatively straight, hairs on outer surface of tibiae inclined at an angle of 45°, and approximately one-seventh shorter than width of segment. Second segment of tarsus considerably curved and approximately seven times as long as the first tarsal segment. Abdomen.—Width of base of cornicles approximately .24. Exact width often difficult to determine because of lack of differentiation between cornicles and rest of abdomen. Hairs on base of cornicles of one kind considerably finer in quality than those on remaining portion of abdomen. Lateral and dorsal portions of abdomen with approximately thirty wax pore-plates arranged in four more or less irregular rows, rows on anterior portion of abdomen with more wax pore-plates than those on posterior portion of abdomen. Cauda broadly rounded, approximately five times as wide at the base as long. Hairs on body long and spine-like. OVIPAROUS FEMALE. Size and general color.—Average length from vertex to tip of anal plate, 3.08. Color essentially similar to that of stem mother, but differing in the Hottes—Descriptions of Aphiidae from Western Colorado. 3 following respects: Head lighter in color; antennal segments five and six alone dusky; tibiae almost uniform in color, very slightly if any darker at apex; tarsi brownish at base, dark brown toward apex; tip of abdomen more farinose than remaining portion of abdomen. Head and appendages.—Average width of head across eyes, .71. Antennal segments with comparative lengths as follows: I1I—.46 to 53, average .50; IV—.16 to .20, average .185; V—.23 to .29, average .255; VI—.14 to .19, average .16 plus .04. Secondary sensoria confined to fifth antennal segment, numbering from 0 to 1, usually 1. Long segment of beak extending to base of metathoracic coxae, and last segment extending to the beginning of the femora. Head with usual transverse line. Thorax.—Dorsal margin of thorax with approximately six very small groups of wax pore-plates. Hind tibiae with approximately fifty sensoria on apical half of segment. Abdomen as in the stem mother except for the wax pore-plates which are very small and considerably lighter in color. Abdomen with posterior portion decidedly narrowed and elongated beyond cornicles. Abdomen in mature specimens usually containing but two or three eggs which are afterward deposited on the needles of the host. ALATE MALE. Average length of two specimens, 2.04. Head and thorax dark brown, shading to black. Abdomen with exception of genitalia light pea green. Antennae with exception of basal portion of third antennal segment dark brown. Beak colored as in stem mother; in length extending to beginning of femora of metathoracic legs. Proportional lengths of antennal segments as follows: I1I—.70 to 71; [V—.24 to .27; V—.80 to .84; VI—.19, plus .07. Secondary sensoria distributed as follows: I1I—85 to 96; IV—82 to 24; V—10 to 19; VI—O. Secondary sensoria distributed on all surfaces and throughout length of segments except on fifth segment where sensoria are more nearly confined to one side. The wings of both specimens are partly injured and consequently not good for study of veination. The hairs on the antennae are comparatively scarce, inclined at an angle of about 45°, and about one and two-fifths as long as the width of the segment. On the outer surface of the hind tibiae, the hairs are about three times as long as the width of this segment. ‘Toward the base of the tibiae the hairs are quite upright, but toward the apex they are inclined at an angle of about 45°. The hairs on the male are much finer in quality than those of the females. Data associated with specimens described here: July 15, 1931, immature stem mother observed; July 31, the mature stem mothers taken; August 5, viviparous female taken; August 24, oviparous female and males taken. All specimens were taken on Picia pugens Englm. growing in a compara- tively small area on the top of Grand Mesa near Skyway, Colorado. The specimens were for the most part taken by vigorously beating the branches of trees, suspected of harboring this species, over a net. After their presence * on a tree was detected by beating, a few specimens were obtained in the usual manner. These aphids occur singly at the base of the needles of the 4 Proceedings of the Biological Society of Washington. present season’s growth. They are not attended by ants. Their protective coloration is ideal, being nearly that of the color of the needles at their base. Once disturbed, the specimens move about very actively, somewhat suggest- ive of large spiders. It is surprising that no alate forms were observed during the collecting seasons of 1931 and 732. On August 16, 1932, bright orange colored specimens, identical in all other respects to specimens herein described were collected.

Hottes—Descriptions of Aphiidae from Western Colorado. 11 This species is very closely allied to Amphorophora davidsont Mason, to which alate viviparous females key in Mason’s revision of the genus Amphorophora. I am provisionally retaining Amphorophora arnicae as a good species until further collecting substantiates my opinion that the species migrates between thimbleberry and Arnica. In the two years that I have collected Amphorophora arnicae, I have never taken it before July 4th, and at that time only alate viviparous females were taken. This might be taken as evidence that the species migrates between thimbleberry and Arnica, were it not for the fact that I have taken but three apterous viviparous females in the two years collecting. The oviparous females are evidently not produced in Arnica, while the males are. This further indicates that a host other than Arnica is the primary one. The differences shown by the males of the two species are but minor differences, with the possible exception of the presence of abdominal tubercles, in the case of the male of Amphorophora davidson and not in Amphorophora arnicae. The fact that the males agree so nearly in peculiar characteristics such as the absence of sensoria on the fourth antennal segment and the short cauda would seem to further suggest that the species are extremely closely allied if not synonymous. Through the courtesies of Professor Glendenning and Dr. Mason, I have been privileged to study cotypic material of the two species concerned.

Apterous viviparous females of this species key with difficulty to Amphor- ophora amurensis Mordvilko (known only from the apterous viviparous female) in Mason’s revision of the genus Amphorophora. While admitting that Amphorophora tigwatensa may be a synonym of the species described by Mordvilko, my specimens differ from the description of Amphorophora amurensis, as translated by Mason, by having the antennae longer than the body, antennal segments three and four not of the same relative lengths, Hottes—Descriptions of Aphiidae from Western Colorado. 13 by the third antennal segments not having capitate hairs, and by the hairs being shorter than three-fifths the width of segment, by the cornicles being imbricated, and by the cornicles being proportionally longer to the length of the body.

Head, thorax, and abdomen bluish with a reddish tinge, entirely pruinose; color not unlike that found on certain varieties of plums when ripe and unrubbed. Anterior margins of head dusky. Margins of thoracic lobes dusky and the four segments anterior to the cornicles with lateral portions usually dusky. Antennae black or very dark brown except for base of third and all of first and second antennal segments, which are only brown or dusky brown. Beak brown with terminal segment darkest. Coxae and trochanters yellowish. Femora yellowish at extreme base, shading gradually to brown, the brown quickly becoming black or blackish- brown. The area thus colored being equal to about one-third of the length of the segment. Tibiae and tarsi black or blackish-brown. Hairs on antennae and legs with their basal papillae yellowish. Stigma yellowish- brown, accessory radial thickening present. Outer margins of wing slightly fuscous. Veins brownish with just a suggestion of a fuscous border. This border is more pronounced along the radial sector than the media. Corni- cles black or very dark brown except for extreme basal portion which may be yellowish or yellowish-brown. Cauda light yellowish brown. Anal plate brownish. Head and appendages.—Average width of head through the eyes, .60. Antennal tubercles well developed. Antennal segments with the following proportional lengths: IJI—1.03 to 1.14, average 1.09; IV—.93 to 1.00, average .965; V—.77 to .83, average .81; VI—.17 to .20, average .19 plus 1.26 to 1.29, average 1.28. Secondary sensoria confined to third antennal segment, arranged in a straight row, quite small and due to dark color of the segment very difficult to distinguish, numbering from 8 to 19, aver- aging 13. Hair on basal half of third antennal segment subequal to width of segment. Hair on apical half of third antennal segment either equal to or longer than width of segment. The beak is short, failing to reach the Hottes—Descriptions of Aphiidae from Western Colorado. 15 mesothoracic coxae by a distance equal to the width of the coxae at their base. Thorax.—Prothorax without lateral tubercles. Radial sector very much bowed. Second fork of media closer to margin of wing than to first fork. Second segment of hind tarsus, exclusive of claws, equal to basal portion of sixth antennal segment. Cornicles varying in length from 1.14 to 1.31, average 1.21. Reticulated area at apex of cornicles varying from .14 to 17, average .16, and never equal to more than one-seventh of the length of the cornicles, usually nearer one-eighth their length. Portion of cornicles not reticulated distinctly imbricated. Cornicles neither constricted nor swollen, but tapering gradually from a rather wide base to the apex. Cauda varying in length from .50 to .57, average .55, usually with four hairs on one side and five on the other, each hair arising from an angular area which causes the sides of the cauda to appear very coarsely serrate. Cauda constricted just before middle. APTEROUS VIVIPAROUS FEMALE. Size and general color.—Average length from vertex to tip of anal plate, 2.73. Average width of head through the eyes, .60. Color essentially similar to that of alate viviparous female; structurally similar in all respects to alate viviparous female. Antennal segments with the following propor- tional lengths: I1I—1.03 to 1.14, average 1.11; IV—.74 to .86, average .77; V—.64 to .76, average .70; VI—.14 to .19, average .16 plus .96 to 1.09, average 1.04.

Reticulated portion of cornicle averaging .16 in length or a little more than one-eighth of the total length of the cornicles. Cauda varying from .57 to .64, average .61. Otherwise similar to that of alate viviparous female. This species is closely allied to Adactynus pseudorosae (Patch) (although it will not key to this species) from which it may be separated by its color in life and by the relative proportional lengths of the third antennal segment and cornicles to each other, and the two of these to the length of the anal vein. It also differs from Adactynus pseudorosae by having the cornicles reticulated for one-seventh or less than one-seventh of their length rather than one-sixth or more than one-sixth of their length. In Dr. Patch’s key to the genus Macrosyphum (Main Agricultural Bulletin #282) speci- mens of this species key to Macrosyphum californicum. In the key to the genus Macrosyphum in the Plant Lice or Aphiidae of Illinois, the species keys to Macrosyphum laevigatae Essig. (The specimens studied by Patch and Hottes and Frison unquestionably being the same species in spite of the use of different names.) From Adactynus laevigatae it may be distin- guished at once by its color. Specimens of this species may be collected on the under surfaces of the leaves and the flower stems of Zygadenus sp. and Sieversia ciliata.

This species in some morphological respects is suggestive of Adactynus granarium (K), (to which it may be keyed in the Plant Lice or Aphiidae of Illinois), from which it differs in size and in characteristics shown by cauda, cornicles, and the presence of pulverulent matter. Holotype.—Alate viviparous female, Skyway, Colorado, August 22, 1932. Morphotype.—Apterous viviparous female, Skyway, Colorado, August 4, 1932.

This species may be collected preferably by beating Dasyphora fruticosa (as they never occur abundant enough to make collecting in the usual manner worth while). Once observed by beating, single specimens may be taken on the undersides of the leaves of the host plant. So far only apter- ous viviparous females have been observed in spite of the fact that alate viviparous females were searched for biweekly throughout two seasons collecting. Specimens of this species are somewhat suggestive of minute specimens of Adactynus pist (Kalt.). Holotype.—Apterous viviparous female; Skyway, Colorado, August 4, 1932, on Dasyphora fruticosa, deposited in U. S. National Museum. Dactynotus wahinkae, new species. ALATE VIVIPAROUS FEMALE.

In light colored specimens there may be distinguished, beginning with the thorax, about ten rows of brownish spots arranged transversely across the Hottes—Descriptions of Aphiidae from Western Colorado. 21 dorsum of the body. These spots show only along the margin of the ab- domen in the darker forms. The spots on the thorax are more or less confluent on the dorsum. On the dorsum of the abdomen each spot gives rise to a hair which is slightly enlarged at the tip. The lateral spots on the abdomen may bear two or more hairs each. Antennae brownish with the apical portion of the segments darker. Beak, cauda, cornicles, and legs as in the alate viviparous female or but slightly darker.

This species may be collected on the flower heads and later on the seed pods as well as on the under-side of the leaves of Delphinium occidentale. It is very difficult to place generically. It differs from Aphis rociadae Cockerell, the only other species recorded from the host, generically, in color, and biologically. I know of no near relative within the genus that I have placed it in. Late in the fall there is a tendency for this species to produce bright reddish-orange colored specimens which are morphologically identical, in all respects, with the species here described.

BY E. D. BALL, Umiwversity of Arizona, Tucson. Treehoppers are as a rule strictly confined to a single host or to closely related species of plants. It is little wonder then that intensive collecting in the arid Southwest should bring to light a number of new species and that a number of these should represent genera, not previously known from the United States, while others represent new and striking adaptations in food plants as compared with their eastern relatives. Palonica nogalana Ball, n. sp. Similar to viredza but smaller, narrower with a higher and more foliaceous crest, green with a dusky line on the back of the crest. Length @ 10 mm., o 8 mm., width 5.5 mm. Pronotum long low acute; crest nearly equilaterally triangular, much higher and more angular than in viridia; as long as in tremulata, but more definitely angled above, the apex rounding with a slight but definite step on the posterior face. Humeral angles one-half longer with the anterior margin less rounding than in viridia. The crest as seen from in front is higher and much narrower with a definite separation between its slope and that of the metapodium. Color light green, not polished as in wiridia. The carina on the apex of crest, and a line bordering the posterior face dusky. The apex of pronotum and elytra smoky. _ Holotype! 2, allotype o’, and a pair of paratypes taken by the writer at Patagonia, Arizona, May 21, 1931. Two male paratypes taken at the same place, May 10, 1931, and one female taken at Nogales, May 23, 1929. Nymphs and adults taken on the valley cottonwood (P. wislizent). The high narrow crest, the long humeral angles and the different shade of green will at once distinguish this species. 1Types in the author’s collection. 2—Proc. Bion. Soc. WasH., VoL. 46, 1933. (25) 26 Proceedings of the Biological Society of Washington. Telamona calva Ball, n. sp. Smaller and darker than gibbera, the crest tall, upright with the dorsal margin nearly horizontal. Testaceous with a light line. Length 9 8 mm., o' 7 mm., width 4 mm. Pronotum moderately long narrow with faint rugae. A tall narrow up- right crest arising just back of the humeral angles as in gibbera, the anterior margin almost upright, rounding over to the nearly horizontal dorsum, which either rounds over to the slightly sloping posterior margin or else becomes oblique posteriorly and the dorsal margin meets the posterior margin in a slight angle. Crest no longer than in gibbera and the pronotum immediately behind it flattened, then arched and carinate before the acute apex. Humeral angles nearly right angled, narrower than in gibbera or tarda. Male inclined to be hairy with a narrow upright crest, lower than in the female, uniformly rounding above. Color rich testaceous; the face and metapodium with a greenish cast, the central carina of the latter dark, anterior margin of crest narrowly light, posterior margin broadly so, the light areas bordered with dark. Holotype 9, allotype o’, and two female paratypes taken by the writer June 24, 1931, on Blue Blossom (Ceanothus thyrsiflorus) growing on a bluff at Big Trees, California. This species should be placed between gibbera and tarda. Xantholobus nigrocincta Van Duzee. This species was described from a single female by Van Duzee and placed in the genus Ophiderma. The writer collected a fine series in 1930 and upon study discovered that the females show the three-humped outline of a Xantholobus quite plainly. The male differs from the female in color as is usual in this genus and is described below. Male smaller than female, black with white markings. Length 5mm. Face, metapodium and pro- notum back to the first inflation white, finely and thickly irrorate and punctured with black, omitting narrow white margins against which the black is emphasized, and increasing in depth of color on the pronotum until it becomes black with a posterior white band and a pair of lateral areas light. The elytral nervures are black; the legs black above, light below. Allotype o, Huachuca Mountains, Arizona, May 4, 1930, taken by the writer. Genus BAJULATA Ball, n. gen. Resembling Vanduzea in size and venation with the pronotum bearing two extremely large inflations. Metapodium about as in Vanduzea, the humeral angles more prominent and placed farther back. Pronotum sparsely pubescent, as seen from above similar in shape to Vanduzea; in profile with two humps like a bactrian camel, the anterior one situated just before the middle, slightly higher and more acute than the posterior one, which is considerably nearer the an- terior one than the apex. The posterior portion of pronotum sloping from Ball—Some New Treehoppers from the Southwest. 27 base of inflation to the blunt apex, which about equals the apical cell. Elytra relatively short and broad. Venation similar to Vanduzea, the outer discal cell broad and only slightly curved, the apical short and broad, the base truncate with the petiole attached a little nearer the costal margin, thus forming a quandrangular second apical. Type of the genus Vanduzea bajula Godg. This genus bears about the same relation to Vanduzea that Xantholobus does to Ophiderma with the exception that in Xantholobus there are typi- cally three inflated areas, an anterior and posterior inflation of about equal size with a smaller median one above and between. In Bajulata the anter- ior inflation appears to be absent and the median one to have increased in size. Amastris lycioda Ball, n. sp. Smaller, paler and with a lower arch than obéegens which it otherwise resembles. A small long oval pale green species. Length @ 4 mm.; o 3 mm. Metapodium not quite vertical and rounding over into the long low arch of the pronotum, which in turn rounds over to the blunt apex. The meta- podium as seen from the front forms an equilateral triangle and the carinate dorsum of the crest is only slightly foliaceous posteriorly, the highest point about the middle instead of in front as in obtegens. Elytra scarcely exceeding the pronotum. Venation similar to that in obtegens except that the apical cell is larger with the petiole nearer the center than shown by Fowler for that species. Color uniform pale green, the males with venter and femora black. Holotype 2, allotype <’, and five paratypes July 24, 1930, five paratypes August and September, all taken by the writer at Tucson, Arizona. This is the first representative of this tropical genus to be taken north of central Mexico. Its small size, green color, and long oval outline will at once distinguish it. Amastris templa Ball, n. sp. Resembling lycioda in form but slightly smaller, rounder, with a broader pronotum. Straw color (green in life). Length 9 3.75 mm.; 33 mm. Metapodium rapidly rounding back to a point back of the humeral angles, where it joins the arch of pronotum without a sinuation. Pronotum as seen from side lower and more uniformly rounding than in lycioda. Apex much broader and more bluntly rounding than in obtegens or lycioda. As seen from in front the metapodium is roundingly narrowing above, the pronotum broader and flatter than in lycioda with only traces of a carina. The elytra are broader and there are usually extra cells along the costa. The apical cell is small and rests against the costa rather than the apex, the base is obtusely angled and the petiole short. Color pale powdery green in life, fading to straw yellow, the venter and femora black in the male. Holotype @, allotype o, and ten paratypes taken by the author at 28 Proceedings of the Biological Society of Washington. St. George, Utah, May 17, 1913. The broader form, more uniform oval and the small cells along costa will readily separate this species. Publilia modesta var, brunnea Ball, n. var. Form and structure of modesta nearly the metapodium rounding back and joining the crest without an angle or sinus. Pronotum smooth, polished, without lateral carinae and with a long acute apex. Color uniform shining mahogany brown. Length o 4.3 mm. Holotype o and one paratype o Trinidad, Colorado, August 8, 1925 (C. J. Drake), one paratype o Ames, Iowa, May 15, 1897, taken by the author. This may prove to be a distinct species when its life history and food plants are determined. Variety reticulata V. D. appears to be a dis- tinct species with an almost vertical metapodium forming a definite angle with the dorsal line, instead of rounding over as in modesta. Stictopelta caerulea Ball, n. sp. Slightly larger and broader than nova. Brownish olive above with lateral caerulean crescents. Length 7-8 mm., width 4.2 mm. Metapodium broader and flatter than in arizona, rounding into the broad flat dorsum of the pronotum, much less arched than in nova, face relatively shorter and broader than in either species, lateral angles broad as in nova. Apex of pronotum as seen from side rounding up from below to a blunt tip. Color pronotum pale olive brown in female, dark olive brown in the male, with the lateral margin from the humeral angle to just before the apex broadly marked with a caerulean blue stripe, the upper boundary of which is arched. The base of metapodium with a white line which extends to the humeral angles. Holotype @, allotype o’, and eight paratypes, September 22, 1929, four paratypes, September 19, 1930, and one October 10, 1931, all taken in Sabino Canyon near Tucson, Arizona, by the author. This is a strikingly distinct and beautiful species allied to varians of Fowler but differing in color. Sticopelta pulchella Ball, n. sp. Shorter and broader than nova with a higher pronotum. Olive brown (female), or dark brown (male), with two transverse white bands enclosing small black spots. Length 6-7 mm., width 4 mm. Metapodium higher and more upright than in caerulea, the pronotum higher and shorter, therefore more arched as seen from the side. The humeral angles broad and rounding. Apex of pronotum broad, abruptly narrowed from both sides. Color, female with the pronotum pale olive green, a broad irregular margined transverse white band just before the dark brown apex, another interrupted white band between this and the humeral angles. The latter appears as a pair of broad white triangles that do not reach the median Ball—Some New Treehoppers from the Southwest. 29 line above. These white areas with a few rather large round dark spots. Male brown to dark brown or pitchy with the same white areas. Holotype @, allotype o, and four pairs of paratypes, Baboquivari Mountains, September 19, 1931, six paratypes Sabino Canyon, September 22, 1929, all taken by the author. Another beautiful and distinct species. Scalmophorus minutus Ball, n. sp. Resembling reézculatus but smaller, narrower with the horn bluntly rounding instead of pointed. Uniform pale cinnamon brown. Length 5-6 mm., width scarcely 1 mm. Face and metapodium in the same plane, the metapodium gradually and regularly narrowing to the slightly foliaceous apex of the horn with only a trace of a carina. Horn as seen from the side extending upwards at a very slight angle, straight or very slightly curved downwards at the apex. Horn as long as the remainder of the pronotum, gradually tapering to a bluntly rounding apex one-half as wide as the base. Pronotum back of horn very low, slender and tapering to the apical cells, with a single strong carina on the apical portion. Venation slightly reticulate with a petiolate apical cell of varying size. Color uniform cinnamon with only the eyes darker. Holotype @, allotype o’, and one paratype taken by the writer on Chihuahua Pine (P. leiophylla), Chiricahua Mountains, August 23, 1931. Hypsoprora nogolata Ball, n. sp. A small straw-colored species with brown mottling. The pronotum long slender and strongly bisinuate, the dorsal process short, nearly upright, much inflated. Length of body 3 mm., of process in female 2 mm., in male, 1 mm. As seen from the front the dorsal process is slightly more constricted above the metapodium than in anatima and less than half as long, only slightly longer than the metapodium or face in the female and still shorter in the male. From the side the dorsal process in the female is inclined anteriorly but is shorter thicker and more upright than in simplex, while the posterior processes are similar. In the male it is very short, about half the height of the metapodium, upright in front and overhanging behind with a faint carina in both sexes. The elytra are coriaceous on the basal half and deeply pustulate, the pustules extending farther along the nervures. The venation is irregularly reticulate. Holotype ¢@, allotype o’, and six paratypes, Nogales, Arizona, September 20, 1931. Hight paratypes, Tombstone, Arizona, June 14, 1932, all taken by the author on the Desert Broom (Baccharis sarothroides), and only on clumps growing singly on dry hills. Microcentrus lynx Ball, n. sp. Resembling perdita, slightly longer and slenderer, with the dorsal pro- cesses taller, parallel margined and overhanging in the female. Color 30 Proceedings of the Biological Society of Washington. brown but appearing almost silver gray owing to the heavy white pubescens. Length 8 mm., width 2.6 mm. Much smaller and narrower than schaefferi, with the super-humeral smaller and more upright in the female, spreading, acute and spine-tipped in the males. As seen from the front the superhumerals in the female are almost upright on their outer margins and do not equal the humerals, while in schaeffert they overhang the humerals by more than the width of those processes. In the male the superhumerals are lower and much more flaring, almost horizontal at the apex and slightly wider than the humerals. As seen from above the male superhumerals are wing-like, angled in front and emarginate behind with an acute tip like the ear of a lynx. Posterior process more strongly arched and crested than in perdita, less so than in schaeffert. Face with a pair of conical protuberances on the upper margin above the ocelli. Color pearly gray due to a heavy pilosity over a cinnamon brown base. Minute brown spots on wings. Holotype 9, allotype o’, and four paratypes, Palmer Lake, Colorado, July 23, 1900, a pair of paratypes, Durango, Colorado, August 3, 1900, all taken from low mat-like clumps of oaks (prob. Q. gambelli), by the author. In general the humerals of schaefferi extend forward while the foliaceous portion is vertical, and in this species they extend upward and the foliaceous portion is horizontal. Microcentrus auirtus, Ball, n. sp. Resembling lynx, slightly stouter, darker, the superhumerals in the female longer, more inclined forward and expanded towards apex, chocolate brown with a light sheen. Length 8-9 mm., width3 mm. Color of schaefferi nearly smaller with the superhumerals in the female extending obliquely forwards and outwards in a straight line much longer and more expanded at apex than in lynx, with the posterior (upper) half obliquely shorter than the anterior lobe. Male superhumerals almost horizontal, inclined forward more than in lynx, and wider toward apex with a similar spine-like tip. Posterior process of same length and with a node-like crest at each end as in lynx. Upper margin of face with a pair of conical protuberances as in lynx. Holotype @, allotype o’, and one paratype Huachuca Mountains, Ari- zona, June 15, 1930, paratypes Chiricahua Mountains, July 5, 1930, August 23, 1931, Santa Rita Mountains, January 30, 1929, July 13, 1930, and two from Granite Dells, Oct. 6, 1929, all taken on oaks by the author. Microcentrus nicholi Ball, n. sp. Much smaller and more fragile than lynz, with small slender superhum- erals in the female and only low carinae in the males. Color yellowish testaceous. Length 6-7 mm., width 1.7 mm. Face short, sharply retreating on a line below the eyes, thus appearing still shorter. Projections on the upper margin above the ocelli broadly angularly protuberant. Metapodium with a definite shelf back of frontal Ball—Some New Treehoppers from the Southwest. 31 projections, then upright to the truncated-cone-like dorsum, the margins slightly carinated and dark lined in the male, the lateral margins obliquely elevated into long triangular projections which are again dark lined in the female. Posterior process short as in caryae, only slightly exceeding the forks of the scutellum. Elytra with the clavus and the corium back to the cross nervures entirely coriaceous and heavily pustulate, beyond this point hyaline. The ovipositor and pygofers are extremely long and slender and the female segment is only broadly excavated. Color testaceous, paler behind the superhumerals and across the base of the clavus, the posterior process white with a black tip. Holotype @ and one paratype 9 taken on pine in the Chiricahua Moun- tains, June 20, 1928, by A. A. Nichol. Allotype o and one paratype o taken by the writer from Pinus leiophylla in the same place, August 23, 1931, named in honor of Mr. A. A. Nichol, whose observations on food plants and life histories of Homoptera have proved to be exceptionally accurate and valuable. Enchenopa permutata Van Duzee. Van Duzee described this species in 1908 from 10 females from St. George, Utah, and two females from Arizona. He called attention at the time to its characters as intermediate between Hnchenopa and Leioscyta and stated that he formerly considered it as the female of L. ferrugipennis var. testacea. This species is common on Lyciwm wrighti in southern Utah and Arizona and the writer has collected hundreds of examples in each area trying to find a male with the dorsal horn like the female. Instead, he has found that all the males are without horns, and that many of the females are hornless. While the rest of the females possess definite horns which vary somewhat in size and in the angle of projections but do not grade down to the hornless condition. ‘The hornless forms are typical representatives of Leioscyta and resemble testacea. They are, however, quite distinct from that form as represented by the types from Rifle and Grand Junction, Colorado. The writer has collected testacea in abundance on greasewood (Sarcobatus vermt- culatus) in western North Dakota, Colorado, Utah, Nevada, and California as far south as the Mojave Desert. He has not taken it in extreme southern Utah or in Arizona, and has never found a horned female. It is likely that the examples of testacea that Van Duzee cites from St. George, Utah, and Arizona, were really the hornless forms of permutata. In 1929 Goding redescribed the horned female as Tritropidia utahensis from a single female from Santa Clara, Utah. This location is only a few miles from St. George, the type locality of permutata. In the same paper he redescribed the hornless form as Lezoscyta trinotata from a single female from Millican, Utah. The female of this remarkable species appears to have had entirely too much attention while the male has not been men- tioned; it may be characterized as follows: Male resenbling the unarmed female, smaller and usually darker, the angle of the metapodium and dorsum very slightly acute but the apex is — 32 Proceedings of the Biological Society of Washington. broadly rounded with the carina less prominent than in testacea or nitida. The anterior sinuation on the dorsum either weak or wanting as it is in the unarmed female. Color varying from soiled straw to dusky brown, an oblique pale band across the pronotum and elytra in the region of the cross nervures empha- sized and black bordered on the pronotum. Length 4~4.5 mm. Allotype co’, St. George, Utah, May 17, 1913, taken by the writer on Lycium. Tylocentrus reticulatus Van Duzee. This species was described from southern Utah and Arizona, where it occurs commonly on the mesquite. Goding has recently redescribed it as Orthobelus felinus from an Arizona female. It is certainly entirely out of place in the West Indian genus Orthobelus even if it had not been made the type of T'ylocentrus.

The discovery of a new species of Aristelliger on Navassa Island by Major Chapman Grant! and the description of a related form from Great Inagua Island by Dr. Noble and Mr. Klingel? have prompted me to re-examine the rather scanty material of that genus from Haiti. In accordance with Dr. Noble’s prediction that a related form might be expected to occur in Haiti, I have found that a small gecko, which I had assumed was the young of Arzstelliger lar, in reality represents a new species, linked closely to the Navassa and Inagua species because of the similarity of their toe structure.

Dimensions.—Head to posterior border of ear, 15 mm.; head and body, 51 mm.; tail (reproduced), 59 mm. Color in alcohol.—Above drab gray; a seal brown stripe originating behind the nostril, continuing on the lores, passing well above the ear-opening and widening above the shoulder as an enlarged blotch; behind this blotch a fainter continuation of the lateral stripe which becomes very irregular posteriorly and fades out on the sides of the tail; six or seven very narrow dorsal bars between these lateral stripes, the anterior interrupted in the middle and ending as a forward-curving blotch on each side of the nape, the remaining bars somewhat similar in shape but paler; a faint irregular roundish marking on the occipital region; traces of wavy crossbars on the upper limb surfaces; upper and lower lips minutely spotted with pale dots; lower surfaces immaculate pale olive buff darkening slightly below the tail. Paratypes.—M. C. Z. 25425, from Pte. 4 Raquette, Gonave Island, col- lected in 1927 by W. J. Eyerdam, is similar to the type in proportions and generally in coloration, although the pattern of dorsal crossbars is stronger than in the type specimen, and the entire body is darker in hue. The upper and lower labials are dark, and the lower surface of the body is heavily powdered with gray dots. This paratype has six upper and six lower labials on the right side of the head to a point beneath the center of the eye; on the Cochran—A New Gecko from Haitt. 35 left side of the head there are seven upper and six lower labials. The chinshields in this specimen fail to meet behind the mental, being separated by a single small scale. The postnasals are much smaller and more irregular. There are about 16 ventral scales and 26 lateral and 28 dorsal granules in the distance between tip of snout and center of eye. M. C. Z. 13847, also from Gonave Island, collected in 1919 by G. M. Allen, is very pale in color and practically devoid of pattern except for a faint suggestion of the wide stripe along the side of the head and neck. It has six upper labials on both sides, six and five lower labials on right and left respectively; the chinshields fail to meet, being separated by one scale; the postnasals are small, numerous and regular, and there are about 13 ventral scales and 23 lateral and 26 dorsal granules in the distance between tip of snout and center of eye. A third paratype, M. C. Z. 13322 from Thomazeau, Haiti, collected in 1919 by G. M. Allen, is very similar to the type in coloration, except that in this paratype-the dark bands on the limbs are somewhat more heavily accentuated. This individual has six upper and five lower labials on both sides of the head; the chinshields are in contact behind the mental; there are but two postnasals, and these are relatively large, followed by much smaller granules; there are about 13 ventral scales and 24 lateral and 28 dorsal granules in the distance between tip of snout and center of eye. Relationships.—As I have already indicated, the new species is very close to the Navassa and Great Inagua species because of their similarity in the arrangement of the terminal phalanges of the digits. From Aristelliger cochranae of Navassa the new species differs decidedly in color pattern, in having a somewhat longer snout, and in having larger granules on top of the snout and between the eyes as well as on the back. From the Great Inagua form, which Noble and Klingel named Aristelligella barbouri, the Haitian species differs in having more lamellae under the toes, and appar- ently also in having a weaker color pattern. These three species differ from Arvstelliger lar of Hispaniola, A. praesignis of Jamaica and A. zrregularis of Cozumel in having more of the digits with “friction pads”’ at their terminations. y od la 7? ? alee hove, Aram ny VES, on oe Learn nine NT be are Senate vee hs vial mest HER NN Ea ae a ae ete soe hy Rie ee dea | Rbk ah oats ae ais , Mi PA ie ee a NA ey 1 Pay) He ‘es00 Ree ) , iY yi or i) a vr W lh a Sep eA Caicis |e me ARS TAL Rs edo Aman Pen | yi ; . i Waa pene Tell es vl inh mye hh coe iy iy a 1 ‘hae ‘ ee rg i iT r } , fei , ue ] ; ¥ Whe ii pase i ri nat yy ee PHF kl an a ee ta ra 1y ALYY i Wyre i{ vo 4 W } , i ; y GC. “Ai i‘ 4 £ me ned A ay) és ra » ) J ite n a Ya a's f i Ty : What i wee J 7 oe mm! i 19 i t p : ¢ 4 Wb 1 ‘ Ra i ; ie i} bet ! : Me Erie ( Z 7 le yore Vol. 46, pp. 37-38 February 20, 1933 PROCEEDINGS BIOLOGICAL SOCIETY OF WASHINGTON 10). A> AN UNDESCRIBED JACK-RABBIT, GENUS LipugJSiU™ 7” FROM CARMEN ISLAND, GULF OF CALIFORNIA, MEXICO.: BY WILLIAM HENRY BURT. In the spring of 1930, when Mr. Harry H. Sheldon visited Carmen Island, in the Gulf of California, Mexico, he collected an adult female black-tailed jack-rabbit which differed appre- ciably both in skull and skin characters from the jack-rabbits occurring opposite on the mainland of Lower California. In January, 1932, the writer obtained three additional specimens from Carmen Island, the four specimens now being in the col- lections at the California Institute of Technology. In my opinion the island specimens differ sufficiently from the known races of jack-rabbits to warrant distinction by name. It is a pleasure to name this island race for Mr. Harry H. Sheldon, who collected the first specimen from the island. Lepus californicus sheldoni, subsp. nov. CARMEN ISLAND JACK-RABBIT. Type.—Female adult, skull and skin; no. 18061, collection of Donald R. Dickey; Carmen Island [ (latitude 26° north, longitude 111° 12’ west), Gulf of California], Lower California, Mexico; March 22, 1930; collected by H. H. Sheldon; original no. 6338. Measurements of type.—Total length, 560 mm.; tail vertebrae, 95; hind foot, 118; ear (from notch, dry), 126. Skull: basilar length of Hensel, 70.9; leneth of nasals, 37.5; breadth of rostrum at posterior termination of premaxillae (taken from outer borders of frontal processes lateral to pre- maxillary tongues), 20.8; depth of rostrum in front of premolars, 20.1; interorbital width (including supraorbital processes), 26.7; least inter- orbital width, 12.8; parietal width of skull, 30.6; diameter of audital bullae, 14.6. 1Contribution from the California Institute of Technology. 4—Proc. Bion. Soc. WassH., Vou. 46, 1933. (37) 38 Proceedings of the Biological Society of Washington. Distribution Known only from Carmen Island, Gulf of California, — Mexico. Characters.—A moderately dark-colored race of the californicus group of jack-rabbits, as defined by Nelson (North Amer. Fauna No. 29, pp. 126-128, 1909), with large audital bullae and with frontal area depressed below plane of supraorbitals. Differs from Lepus californicus xanti Thomas, as represented by specimens from Cape San Lucas, Los Burros, and Delores Bay, Lower California, in more nearly iron gray coloration with only a trace of the pinkish buffy of the upperparts which is so notice- able in wanti, in larger, more inflated audital bullae, and in more depressed frontal area in region of supraorbitals. Skull similar to that of Lepus californicus martirensis Stowell, but relatively and actually broader with larger bullae. Differs from Lepus californicus magdalenae Nelson chiefly in darker, less buffy, coloration and larger size. Remarks.—Jack-rabbits were seen only at the north end of Carmen Island, particularly along the foothills east of the salt works where there was a rather dense growth of mesquite. Vol. 46, pp. 39-40 February 20, 1933 PROCEEDINGS | aig BIOLOGICAL SOCIETY OF WA sHINGTON Sen A NEW SWIFT OF THE GENUS REINARDA FROM VENEZUELA. BY J. H. RILEY.! Several years ago the United States National Museum acquired a single specimen of Reznarda collected in the Brazilian state of Ceara. Later when a series of six specimens were received from the National Geographic Society collected on the Brazo Casiquiare, Venezuela, it was at once apparent that two forms were represented. Lately to clear the matter up, the American Museum of Natural History has kindly lent me a series of this genus from northeast Brazil and the Academy of Natural Sciences of Philadelphia has forwarded the type of Cypselus squamatus Cassin. To the authorities of both insti- tutions I wish to extend my thanks. An examination of the above type shows that the Venezuelan form is the one requiring a name. It may be known as Reinarda squamata semota, subsp. nov. Type.—Adult female, U. S. National Museum, no. 326,806, El Mango, Brazo Casiquiare, Venezuela, February 5, 1931, collected by Holt, Blake, and Agostini (original number 4988). Similar to Reinarda squamata (Cassin), but the upperparts a shining greenish black instead of brownish black; the pectoral band broader and darker; the feathers of the throat and center of the breast only fringed with white, the dark bases of the feathers showing plainly and predominating instead of being predominantly white; under tail coverts a shining greenish black with only a very narrow white fringe on the inner web instead of nearly the whole inner web being white and the outer web sometimes narrowly edged with white. Wing 106; outer tail feather 71; middle tail feather 31.5 mm. Remarks.—The U. S. National Museum received six specimens collected 1Published by permission of the Secretary of the Smithsonian Institution. 5—Proc. Biou. Soc. WassH., VOL. 46, 1933. (39) 40 Proceedings of the Biological Society of Washington. on the Brazo Casiquiare, Venezuela, by the National Geographic Society’s Brazil-Venezuelan Expedition. I am indebted to the authorities of the American Museum of Natural History for the loan of eleven specimens of Reinarda from the states of Bahia, Piauhy, Parahyba, and Ceard4, Brazil, and to the authorities of the Academy of Natural Sciences of Philadelphia for the loan of the type of Cypselus squamatus Cassin. The U.S. National Museum previously to the receipt of the Venezuelan series possessed only a single specimen of Reinarda from the state of Ceard, Brazil. It is a very light colored specimen with scarcely any light edging to the feathers of the back; in fact, it is much lighter than any specimen in the American Museum series mentioned above. It is so light that it is either aberrant or a very old bird. All the other specimens from Brazil have the feathers of the upperparts more or less fringed with whitish. In the Venezuelan series the upperparts are much less heavily fringed with whitish; in fact in the type of semota the light edges to the upperparts are very faint; it is the only one in the series marked as adult. In the series examined from Brazil all, except one, of the specimens have the under tail coverts predominantly white while in semota this area is predominantly black. The Venezuelan series is fairly uniform; the type has the edges to the feathers of the upper- parts less prominently fringed with whitish. The type of Cypselus squa- maius Cassin agrees with the series from Brazil rather than with that from Venezuela, Cassin says that his type was presented to the Academy by Dr. Henry G. Dalton of Georgetown, British Guiana, who stated it was a @ common resident bird in that country. The species has been recorded from Peru, but birds from there will almost certainly prove to be different from the more eastern birds. There appears to be no appreciable difference in size between the Vene- zuelan and Brazilian series.

RAYMOND HALL anp ROBERT T. ORR, Museum of Vertebrate Zoology, Univ. of California, Berkeley, Calif. Knowledge of the existence in the Museum of Vertebrate Zoology of the series of topotypes, obtained in 1930 by Miss Annie M. Alexander and Miss Louise Kellogg, of the several kinds of pocket gophers named from eastern Washington and Oregon, induced one of us (Orr), when visiting that region, to direct special effort toward obtaining additional specimens, from other localities, judged as probably of importance in con- tributing to a better understanding of the genus Thomomys there. One result of this effort was the taking of certain specimens, inthe Wallowa Mountains of Oregon, which, when studied together with other specimens previously taken from the same mountain mass, give basis for recognition of the here- tofore unnamed geographic race described below. Thomomys quadratus wallowa, new subspecies. Type.—Male, adult, skin-and-skull; no. 54701, Mus. Vert. Zool.; Cather- ine Creek, seven miles east Telocaset, 3500 feet altitude, Union County, Oregon; June 29, 1932; collected by Robert T. Orr; original no. 570. Range.—Wallowa Mountains of northeastern Oregon and adjoining mountains in southeastern Washington. Diagnosis.—Size: small (see measurements). Color (summer pelage): near (1) Snuff Brown! above; sides lighter (more grayish); underparts washed with Cinnamon Buff; hind feet and tail whitish. Skull: rostrum short and broad; premaxillae extending considerably behind nasals; zygomata nearly parallel but not broadly expanded; tympanic bullae small; dorsal margin of foramen magnum evenly rounded; maxillary arms of zygomata abruptly depressed. Comparisons and relationships——As compared with the geographically adjacent Thomomys columbianus Bailey, T. q. wallowa, cranially, is smaller with less well developed temporal ridges, in side view has the maxillary 1Capitalized color terms after Ridgway: color standards and color nomenclature, 1912. 6—Proc.

The two last mentioned characters show approach to 7’. q. quadratus, from which wallowa differs jn smaller size, less well developed temporal ridges, less widely expanded zygomatic arches, more inflated tympanic bullae and in having the maxil- lary arms of the zygomata, in side view, not as nearly vertical. Selected differences of 7. g. wallowa, from Thomomys fuscus fuscus (specimens from Smith Mountain, Adams County, Idaho) are as follows: Auditory bullae less inflated ventrally and in mastoid portion; maxillary arms of zygomata more nearly vertical; rostrum relatively, as well as actu- ally, shorter and broader; premaxillae extending farther behind nasals; dorsal margin of foramen magnum, without, rather than with, distinct indentation. The three last mentioned characters are ones in which wallowa agrees with T. q. quadratus. The two first mentioned features are ones in which wallowa is intermediate as between quadratus and fuscus. Other features in which wallowa resembles fuscus and departs from quadratus are: small size; narrow braincase; and narrowness across the zygomatic arches. Four specimens, two of which are young, from Ochoco Ranger Station, 4000 feet altitude, Crook County, Oregon, deserve mention in the present connection. The locality is geographically intermediate as between the territories known to be inhabited by quadratus and wallowa. The skulls of the two adults are intermediate in general size as between wallowa and quadratus and the degree of inflation of the tympanic bullae is intermediate as between these two forms. The braincase is wider as in quadratus. Indeed the skull throughout is relatively wide as in quadratus and further agrees with that form as regards the nearly vertical position of the maxil- lary arms of the zygomata. The specimens are referred to quadratus. At the same time, they are regarded as in the nature of intergrades toward wallowa and on this account we think justify use of the specific name quadratus with the here newly proposed name wallowa. T. q. wallowa itself is intermediate in cranial characters as between quadratus and fuscus. In fact, it stands very near the center of the gap which separates the two forms. By one line of reasoning these structural features of wallowa might justify uniting fuscus and quadratus as subspecies of a single species. However, a gap of some size, even though only about half as great as formerly thought, still exists between fuscus and animals of the quadratus type. If, and when, intermediates are found between fuscus and wallowa, as we have just described from Ochoco Ranger Station, between quadratus and wallowa, then we should have but little hesitancy in treating quadratus and fuscus as geographic races of one and the same species. However, we have seen no specimens from intermediate localities which bridge the gap between the long, narrow rostrum of fuscus on the one hand and the short, wide rostrum of quadratus and wallowa on the other. Specimens examined.—Total number, 8, as follows: Anthony, Baker County, Oregon, 4; Catherine Creek, seven miles east of Telocaset, 3500 feet altitude, Union County, Oregon, 2; twenty-five miles southeast of Dayton, Blue Mountains, Columbia County, Washington, 1; Humpeg Falis, Columbia County, Washington, 1. 43 Hall and Orr—A New Race of Pocket Gopher. *sso001d [BurAIOB] ay} JO asVq oy} JO PUS [B10}¥[ 9} 4B VI[IXBUI OY} 0} S[esvM 04} JO opI0g IOLIej}UB 94} JO O[PPrU oY} WO} UEYe} SUA OATS OIOY SB UUNIZSOI Jo YYSUSTz OP ON re 89 “OD eyVG O BILE PO SO 6 OTE CEO ne OS "aI “OD woyVG © TILE C2000 0) Oe OUR OC ON AO “op yVG@ © 6OLE Ce 1) 90 Ge I 0 Ole Ol cS Lae Gh AO “OD uo YP ed4y, OO Oe OV LG 06 YSeM “OD BIquINOH 5 66ITZ So Fe et iS} 0g og = 09 og © © 2 Ste ee @ 5 Ss S = EF 3" a © = Z ee < Me 6 Se Se Se ee E 3 oo 5 a e 3 oe > = ct 9 - © 5 5 © or g R = 5 EE: ee ck a 3 @ aD ——— ct ee ae + 4 2 > B &¢ Ss 5, S “‘pnoyjom snyoiponb shwowmoy J, 40 SNAWIOGdG LIAGY DALY JO ‘SUMLAWITIY, NI ‘SLNEWaYOSVa] i 7 rah es i at By! ty folie a | ) 4a) ’ vey es i ' i 4 Bay! ) da ole aE!

J. DRAKE anp H. M. HARRIS, Ames, Iowa. The present paper is based upon material belonging to the U. S. National Museum, the Carnegie Museum (Pittsburgh), and the private collection of the writers. It contains descrip- tions of six species of Rhagovelia, six species and a variety of Velia, and three species of Microvelia. The place of deposition of the types is indicated after the description of each species. Velia capillata, n. sp. Brown to dark brown, the pronotum darker, sometimes blackish; rather densely clothed with long, erect, fine, brownish hairs. Head brown, hairy, with the usual impressed lines and a large fovea on each side above. An- tennae long, slender, rather thickly clothed with both long and short hairs; proportions, 35 : 20: 42: 45. Rostrum reaching almost to middle coxae. Pronotum coarsely and deeply pitted, sometimes with an indistinct median carina, the sides constricted before the middle, the base rounded behind, the humeri quite prominent. Hemelytra infuscate, the veins prominent and paler, an irregular longitudinal patch at the base and a rounded spot on each side of membrane near apex whitish. Body beneath brown. Legs fuscous brown, tending to be lighter toward base, rather long, very hairy; the tarsi of intermediate legs with the basal segment short, and the apical about as long as the other two conjoined. Male.—The last segment of venter subequal in length to preceding one, its apical margin deeply excavated. Clasper long, strongly bowed, its apical portion flattened and expanded. Pronotum not as broadly rounded behind as in female. Length, 4.2 mm.; width, 1.73 mm. Holotype, macropterous male; allotype, macropterous female, Chapada, Brazil; Carnegie Museum. Paratypes, several males and females taken with types, in collection of the authors and Carnegie Museum. Velia capillata, var. cognata, n. var.

Holotype, macropterous male, Maranhao, Brazil, writers’ collection. Velia hungerfordi, n. sp. Dark brown, legs and antennae paler, each hemelytron with an elongate stripe on basal third and a slightly broader and shorter stripe along median line at apex white. Head with the usual impressed lines. Antennae moderately stout, apical segments slightly darkened; proportions, 32 : 26: 28: 33. Rostrum extending to end of mesosternum. Pronotum very coarsely pitted, with a fairly distinct raised median line, rather broadly rounded behind. Legs long, hairy, segments two and three of intermediate tarsi subequal. Sides of thorax and body beneath, except last segment of venter, deeply and coarsely pitted. Length, 4.61 mm.; width, 1.76 mm. Holotype, winged female, Chapada, Brazil; in collection of Carnegie Museum. Paratype, winged female, Brazil; in authors’ collection. The white markings on the eyltra, the antennal proportions, and the pitted venter serve to identify this pretty species. It is named in honor of Dr. H. B. Hungerford, who has taken a very keen and active interest in the aquatic and semiaquatic Hemiptera. Velia kahli, n. sp. Brownish black, the disc and anterior portion of pronotum brown; legs and antennae brown. Elytra with a basal streak and a rounded spot on disc of membrane whitish; upper surface sparsely clothed with long black hairs. Pronotum deeply pitted, with a median raised line, broadly rounded behind, the humeri prominent. Head black, with usual impressed lines. Antennae moderately long; proportions, 28 : 16:37:37. Rostrum ex- tending slightly beyond middle of mesosternum. Legs clothed with short, recumbent hairs; intermediate tarsi with segments two and three subequal; hind femora bowed, slightly longer and thicker than intermediate. First genital segment of male strongly constricted, armed on each side with a flattened, triangular tooth, the hind margin deeply and broadly excavated at the middle, also with a distinct notch on each side. Last genital segment short and plump. Clasper broad, curved, constricted near the base and beyond the middle, the apex broad. Length, 4 mm.; width, 1.2-1.4 mm. Holotype, winged male and allotype, winged female, Chapada, Brazil; in collection of Carnegie Museum. Paratypes, 2 males and 3 females, taken with types, in collections of Carnegie Museum and the writers. In this species the connexivum is indistinctly marked with paler at the basal angles of the segments and the edge is beset with numerous, short black spinules. The species is named in honor of Dr. Hugo Kahl, in charge of the insect collection at the Carnegie Museum. Velia parilis, n. sp. Very similar to V. kahli, n. sp., but differing from it in the slenderer body and the structure of the male claspers. Pronotum dark brown to Drake and Harris—New American Veliidae. 47 brownish black, the disc with a large, elongate brown patch; median carina moderately distinct. Markings of hemelytra and antennal proportions as in kahlz. Length, 4 mm.; width, 1.2-1.38 mm. Male.—Last segment of venter a little longer than preceding, truncate behind. First genital more deeply excavated behind than in kahit, the teeth smaller and narrower. Clasper long, curved, the apex sharply curved and pointed. Holotype, winged male, and allotype, winged female, Chapada, Brazil; in collection of Carnegie Museum. Paratypes, male and female, taken with type; in authors’ collection. The female of this species is very difficult to separate from that of kahli, the male, however, has very differently constructed claspers. Velia nexa, n. sp. Very similar to the two preceding species in size, form, and markings. Pronotum dark brown, the large central part of disc lighter; with a fairly distinct median carina, deeply and coarsely pitted, with a row of promi- nent pits on the collar as in above species, humeri prominent. Legs and antennae very dark brown. Head with usual impressed lines and pits. Antennal proportions, 30 : 18 : 35 : 35; last segment paler. First genital segment of male depressed on each side, with a broad, flattened ridge along median line, without teeth or lateral notches, the apex slightly excavated at middle. Clasper hairy, long, broad, stout, curved inwardly and narrowed and darkened toward the apex. Length, 3.54 mm.; width, 1.35 mm. Holotype, winged male, and allotype, winged female, Maranhao, Brazil, in authors’ collection. This species belongs to the same section of the genus as rotundanotata Hungerford, but is darker in color than that species, with less prominent humeri, without spinules and with differently formed genital claspers. The genital characters are very different from those of kahlt and parilis, n. spp. Velia splendoris, n. sp. Apterous form.—Brown, the entire body conspicuously armed with short black spinules and somewhat sparsely clothed with long, fine, dark hairs. Head with the usual impressed lines, the spinules prominent and directed upward and slightly posteriorly. Antennal proportions, 25 : 18 : 22 : 28. Rostrum reaching beyond middle of mesosternum, its apex black. Legs testaceous to brownish testaceous, all femora rather thickly beset beneath with black spinules, the coxae and trochanters also with a few spinules. Intermediate legs with last tarsal segment distinctly longer than the preceding two segments together. Pronotum broadly rounded behind, rather coarsely pitted, with raised median ridge more distinct anteriorly; the front portion transversely raised behind collar. Connexivum moder- ately broad, the margins slightly bowed, the spinules slightly larger than elsewhere. Abdomen above with basal parts of segments two, three, and 48 Proceedings of the Biological Society of Washington. four with closely set, large foveae. Sides of thorax deeply, coarsely pitted. Last segment of venter of male slightly emarginate behind. Genital seg- ments short and plump, the clasper long, strongly bent near base, the distal part curved and somewhat foliaceous.

Paratypes, three males and one female, taken with types; in collections of authors and Carnegie Museum. Rhagovelia hambletoni, n. sp. Apterous male.—Black, the sides of pronotum and body beneath with an aenous luster; clothed with fine pale to brownish hairs. Basal portion of first antennal segment, coxae and trochanters of front and hind legs, base of front femora, and edge of intermediate acetabula pale to testaceous. Antennal formula, 39 : 22: 26:25. Pronotum short, about one-fourth as long as broad, its hind margin slightly sinuate, the flavous spots fairly distinct. Mesonotum arched, a little shorter than broad, rounded behind. Connexiva slightly widened toward middle, the margins shiny, almost straight. Abdomen above with shiny patches on apical three segments. Venter with an indistinct median ridge toward base, the last segment black, nearly one and a half times as long as preceding, slightly depressed on each side of median line near the posterior margin, its apical margin slightly excavated. Genital segments plump, the last segment above bluntly rounded at apex. Intermediate legs, 77 : 59 : 36: 36. Posterior femora slightly enlarged, armed beneath near the middle with a long, sharp, backward pointed tooth and from there to apex with seven or eight much shorter teeth, these diminishing in size toward apex. Posterior tibia with a short apical spur. Apterous female.—Color, markings, and clothing similar to male. Con- nexivum broad, strongly reflexed behind, the basal segments clothed along inner margin with long brown hairs, the apex slightly raised and clothed with a compact group of stiff hairs. Intermediate legs, 38 : 64 : 40 : 39. Posterior femora armed within at apical third with a prominent spine and sometimes from there to apex with three or four much smaller teeth. Venter slightly carinate down the middle, the last segment shiny black, its apical margin convexly sinuate. Length, 3-3.4 mm.; width, 1-1.21 mm. Holotype, apterous male; allotype, apterous female, Vicosa, Minas Geraes, Brazil, June 6, 1932, E. J. Hambleton; in collection of authors. Paratypes, several apterous males and females, taken with types. This pretty little species belongs to the group with short pronotum. It is named in honor of the collector, who is taking a keen interest in Brazilian insects. Drake and Harris—New American Veliidae. 49 Rhagovelia tantilla, n. sp. Black, clothed with very fine brown pubescence, pronotum with a transverse yellowish-brown spot in front, its sides and the entire ventral surface, excepting last abdominal segment and genital segments, grayish; basal portion of first antennal segment, all acetabula, the anterior and posterior coxae and trochanters, and basal portion of front femora pale testaceous. Head with the usual impressed lines, vertex somewhat arched. Antennae moderately long, first segment strongly curved; formula, 30:18: 20:21. Pronotum about one-third as long as broad, raised posteriorly. Mesonotum evenly arched above, without median impression, about three times as long as pronotum, somewhat rounded behind. Inter- mediate legs, 65: 45 : 25: 32. Posterior tibia straight, without evident spine at tip. Length, 2.4-3 mm.; width, 1.1-1.2 mm. Male.—Connexivum with outer margins slightly rounded, without pale markings. Posterior femora slightly incrassate, reaching slightly beyond apex of genital segments, with a long, fine, black spine at the middle within and with five or six regularly shorter spines before apex. Venter strongly convex, with longer hairs on median part; the last segment shiny, with faint median keel to each side of which it is slightly depressed. Genital segments short and plump, the last segment bluntly rounded behind. Clasper short and broad. Female.—Hind legs with femora slightly less swollen than in male and the spines a little smaller. Abdomen smooth above, without hairy coating except on basal two segments, the apical two segments with shiny patches. Connexivum broadest at middle, quite hairy along the sides and at apex. Last segment of venter shiny, terminal genital segment broadly rounded. Holotype, apterous male, and allotype, apterous female, Punta Gorda, British Honduras, in authors’ collection. Paratypes, numerous apterous males and females taken with types. This species is somewhat closely related to regalis D. & H., from which it may be separated by its smaller size, shorter appendages, more convex body, narrower head, less strongly widened thorax, and differently con- structed claspers of male. In all females at hand the connexiva are turned up and the abdomen longitudinally depressed so as to form a trough-like depression on the dorsum. Rhagovelia plana, n. sp. Apterous male.—Black, rather small, distinctly flattened, and narrowed posteriorly. Pronotum flattened, short, about one-fourth as long as mesonotum. Antennae moderately long, with bristly hairs as in other species; formula, 40 : 20 : 22: 22. Connexivum not produced at apex, the margins shiny, nearly straight, and converging posteriorly. Intermedi- ate legs, 80: 52: 36:33. Hind femora moderately incrassate, with a long spine near the middle and shorter spines from there to apex; shorter than tibia (60 : 66), the latter straight, with an indistinct spur at apex. Venter with last segment a little longer than the preceding, truncate at the apex. Genital segments plump, black. All acetabula, intermediate and posterior coxae, and trochanters pale. 50 = Proceedings of the Biological Society of Washington. Apterous female-—Mesonotum not so strongly depressed as in male. The hind femora not quite as incrassate as in male, armed as there. Con- nexivum much broader than in male, the outer margin rounded and be- coming quite hairy posteriorly. Tip of abdomen also hairy. Length, 2.8-3 mm.; width, 1.2 mm. Holotype, apterous male, and allotype, apterous female, Punta Gorda, Br. Honduras; in authors’ collection. Paratypes, numerous apterous males and females taken with types. This species is closely allied to regalis D. and H. and tantilla, n. sp. It may be recognized by its depressed form and short legs. The female of the latter has a peculiarly formed abdomen that will aid in its identification. Rhagovelia ainsliei, n. sp. Apterous male.—Black, the margins of connexivum, basal portion of first antennal segment, and all coxae and trochanters testaceous to flavous. Body finely pubescent, also with short brownish hairs, the legs with longer pale hairs in addition to blackish bristles. Antennae moderately long; proportions, 50 : 32 : 23 : 22. Head black, with the usual impressed lines. Pronotum with bristly hairs along its sides, the disc deeply and coarsely pitted, with a fairly distinct median longitudinal carina, the front and sides plumbeous, with an indistinct testaceous spot on each side before apex, as long as broad, the base rounded, covering mesonotum. Connexivum with margins nearly straight, tapering regularly to apex. Anterior tro- chanters armed with a short, brownish spine before apex. Proportion of intermediate legs, 104 : 68 : 45: 42. Hind trochanters with a few small, black teeth. Hind femora moderately to strongly incrassate, armed at basal two-fifths with a long, backwardly projecting spine-like tooth, from there to apex with a double row of short teeth, the base before long tooth also with a row of short teeth. Posterior tibia nearly straight or sometimes distinctly sinuate, armed within with short, stout teeth, those at apical third often much larger than others, the apex with a stout spur. Venter sharply carinate down the middle on basal two segments, the last segment shiny, strongly impressed on each side of the broad, median, somewhat triangular portion. First genital segment conspicuously clothed with pale hairs; last segment above strongly mucronate. Clasper moderately long and broad. Apterous female——Color, markings, punctuation, and general body clothing as in male. Antennae, 48 : 29 : 21: 20. Connexivum strongly reflexed against the sides of the abdomen, with long brownish hairs along basal margin, narrowed toward apex, the tips with tufts of black hairs. Last segment of abdomen fringed with long brown hairs. Last segment of venter brown, shiny, about twice as long as preceding. Posterior legs with femora moderately slender, armed before distal third with a slender tooth and with several smaller teeth from there to apex. Genital segments hairy, the last strongly mucronate. Winged male.—Pronotum longer than broad, triangular behind, the tip raised and slightly produced, the median carina fairly prominent. Winged female.—Pronotum produced behind into a long horn, this Drake and Harris—New American Veliidae. 51 curved downward, and its apical portion densely clothed with long, brown hairs. Length, 3.8-4.1 mm.; width, 1.3-1.4 mm. Holotype, apterous male; allotype, apterous female, Guatemala City, Guatemala, C. N. Ainslie, collector, in collection of the writers. Morpho- types, winged male, and paratypes, several winged and wingless males and females, all taken with types. This species is perhaps nearest related to R. spinigera Champion. The intermediate femora of the females lack the strong constriction character- istic of that species, although they are somewhat compressed dorso-ven- trally. The males may be discriminated by the spine on the trochanter, the nature of the last segment of venter, the hairy genital segment, the sharply pointed apical segment, and the more triangular base of pronotum of winged form. - Rhagovelia ignota, n. sp. Winged male.—Size, form, color, and markings very similar to R. spinigera Champion. Antennal proportions, 40 : 22: 21 : 22; intermediate legs, 80 : 60: 26: 38. Posterior femora moderately to strongly incrassate, armed as in spinigera. Venter carinate along median line in front and depressed on distal four segments; the last segment deeply and roundly excavated behind, with a very strongly raised prominent hump on each side, the crest of each hump being a little in front of the middle of the segment. First genital segment with the posterior portion beneath hairy and very greatly swollen. Clasper a little broader and less pointed than in spinigera. Pronotum strongly pitted, faintly carinate along median line, and angularly produced behind. Apterous male.—Pronotum broadly rounded behind and not so distinctly carinate along median line. Connexivum with the margins nearly straight; bordered with brown. Hind femora strongly incrassate. Posterior tibiae straight, with a spur at apex. Female.—Very similar to R. spinigera Champion. Pronotum a little longer, its sides in front more depressed, and in the apterous form the base not so broadly rounded behind. Legs constricted as in spinigera. Length, 4—4.2 mm.; width, 1.5 mm. Holotype, winged male, Chiquimula, Guatemala, June, 1930; in authors’ collection. Allotype, winged female, Tegucigalpa, Honduras, August 18, 1918, F. J. Dyer, collector; U.S. N. Museum. Paratypes, two males and four females, taken with the allotype. The male is recognizable at a glance by the peculiar structure of the apical segment of the venter and the hairy and strongly tumid first genital segment. As in spinigera, female specimens sometimes bear tufts of long hairs at the apex of the abdomen. Rhagovelia cuspidis, n. sp. Black, thickly clothed with fine golden pubescence, the front margin of pronotum, connexival margins, base of first antennal, prosternum, all coxae, anterior and posterior trochanters, base of anterior femora and part of hind femora testaceous to brownish testaceous. Head with the : 52 Proceedings of the Biological Society of Washington. usual impressed lines. Eyes large, coarsely faceted. Antennal formula, 45 : 25: 27: ?, the second segment with long hairs on dorsal surface, the third slightly expanded. Pronotum extending over mesonotum, broadly rounded behind, with an indistinct median ridge, with rather numerous indistinct, but deep punctures. Abdomen tapering slightly posteriorly, the margins nearly straight, terminating behind in prominent somewhat laterally projecting spine-like processes; last segment a little longer than preceding, with a patch above shiny, the apex truncate. Last genital segment ending in a long, sharp process. Legs moderately hairy, the anterior tibiae strongly compressed, somewhat expanded and shallowly excavated beneath. Intermediate legs long; formula, 102 : 76 : 35 : 38. Apterous male.—Venter bluish black, clothed with longer hairs, last segment shiny black, strongly depressed behind, the apex truncate. Genital segments plump, the first segment carinate along median line at base. Clasper long, very broad at base, the terminal portion sub-cylindrical, of about equal width throughout, slightly curved inwardly, blunt at apex and about three times as long as basal portion. Hind femora rather strongly incrassate, reaching to genital segments, armed with nine or ten progres- sively shortened, black-tipped testaceous spines; the first of these is much longer than the others and situated slightly before the middle; also armed along the basal half, before the long spine, with a distinct row of closely set, black teeth and along the distal half, beneath the spines, with an irregular row of short, black teeth. Posterior trochanter with numerous short black teeth. Hind tibia nearly straight, armed within with numerous short black teeth, the apex with a long, stout, slightly-bent black spur. Apterous female.—Posterior femora slightly incrassate, with a row of black-tipped, testaceous spines as in male. Connexivum broader than in male, the outer margins nearly straight, the apical spine as in male. Length, 4.42 mm.; width, 1.15 mm. Holotype, apterous male, and allotype, apterous female, Punta Gorda, British Honduras; authors’ collection. Paratypes, three apterous males, taken with types. The connexival spines, the mucronate terminal abdominal segment, and the character of the armature of the hind femora will serve to separate this species from allied forms. Microvelia diffidentis, n. sp. Moderately large, obovate, brownish black with brown markings; moderately hairy. Head rather long, black, with a prominent median impressed line. Eyes brown, rather large. Antennae brown, lighter at base, rather long and slender, the first segment not greatly enlarged, II slightly more hairy beneath than others, it and III also with a few setae above; formula, 19: 18: 28:22. Pronotum narrowed anteriorly, much broader than long, indistinctly pitted; a transverse spot in front, the median line and a smaller spot behind brownish. Connexivum quite hairy, the outer margins and segmental sutures blackish. Legs brownish, paler toward base, moderately hairy. Intermediate legs much the longest. Last segment of venter as long as the two preceding ones conjoined. Drake and Harris—New American Veliidae. 53 Length, 2.52 mm.; width, 1.20 mm. Holotype, apterous female, Sao Matheos, Brazil; in authors’ collection. Paratypes, four apterous females, taken with type. The hairs of the prosternum and connexivum are black and quite bristly. This species and the following one differ from other known Microvelia in the structure of the intermediate legs, reminding one in this respect of Rhagovelia except that the tarsi are not constructed as in that genus. Microvelia turmalis, n. sp. Form and general color pattern somewhat similar to diffidentis, n. sp. Head black, brownish along the eyes, with the usual impressed lines. Antennae brownish black, the first two segments paler, II and III with bristly setae as in difidentis; formula, 15 : 14 : 20: 18. Rostrum not quite attaining middle of mesosternum. Pronotum broader than long, rather deeply pitted, black, with a transverse brownish spot behind collar, this brownish portion smooth and slightly raised, the basal margin broadly sinuate. Connexivum with the segments largely brown, not so hairy as in diffidentis; in female terminating at apex in rather long, brown spines. Legs brownish, darker above, the tarsi blackish. Intermediate legs much the longest. Body beneath grayish black. Last venter about twice as long as the preceding. Length (o'— @), 1.9-2.44 mm.; width, 1.3 mm. Holotype, apterous female, and allotype, apterous male, Punta Gorda, Br. Honduras; in authors’ collection. Paratypes, many males and females taken with types. This species is closely related to diffidentis, n. sp. The connexival spines serve to identify the species at once. In the male the connexivum does not terminate in spines. Microvelia venustatis, n. sp. Very small, very broad through humeri, brownish-black, collar testa- ceous; wings brown, a little lighter at the base; antennae brown, the basal segment in greater part testaceous; legs brown, the trochanters and most of the femora testaceous. Head short and broad, with brownish pubescence. Eyes large, widely separated. Antennae rather short, segment I stout and curved, III slenderest, IV stout and fusiform; formula, 8:6: 7: 11. Pronotum arched, almost three-fifths broader than long, with a distinct median ridge, triangularly produced and somewhat rounded behind, the humeri rounded. Hemelytra brown, paler toward base, the nervures prominent and darker. Length, 1.6 mm.; width, .8 mm. Holotype, winged male, Brazil; in authors’ collection. This pretty little species is most closely allied to marginata Uhler and summerst D. & H. From the latter it differs in being a little longer and by having much more prominent humeri, and much narrower abdomen. From marginata it is to be discriminated by the much less distinct median line on head, the concolorous pronotum, shorter body and _ proportionally broader pronotum. ett i mn ae mH 7) 7 ‘a fi wl Th : 5 i ) q y ' i « ‘ . ‘Vet; Hi i Hii ve »! be hs ? aa ‘ shee eae UL Late vi AB tee oh eM Pulte Giau7 a rf 7 }. wy a & 4 ‘ « J 7*} i ‘ dit me bra ‘a ,. \ Bia * 7 a a ‘ a dd ’ 1 ‘ - ‘ t i is iy | y v i : i 4; y By i j { ‘i rae si Nee a mh me i) ths we r SAG ' 4.06) is Vol. 46, pp. 55-56 Mareh’24, 1933 OF THE f BIOLOGICAL SOCIETY OF WAS BATS FROM SZECHWAN AND KWHEICHOW, CHINA. BY COLIN CAMPBELL SANBORN.! Among the thirteen species of bats collected by the Marshall Field Chinese Expedition of Field Museum of Natural History are five of especial interest from localities which greatly increase their known distribution. In addition to these, the following also were taken: Rhinolo- phus blythi szechwanus And., R. rouxt sinicus And., R. episcopus G. M. Allen, Myotis laniger Peters, M. moupinensis Milne- Edw., Pzpistrellus pulveratus Peters, Murina aurata Milne- Edw., all from Szechwan; and Hipposideros armiger Hodgson from Szechwan and Kweichow. Lyroderma lyra sinensis Andersen and Wroughton. Eucheira sinensis Andersen and Wroughton, Ann. Mag. Nat. Hist. (7), 19, p. 186, 1907—Amoy, Fukien, China. A series of thirty-five specimens was taken at Ta Cho Fu (Lat. 29° 20’ N., Long. 102° 45’ E..), western Szechwan. This series, compared with six specimens of sinensis from Fuching, Fukien, kindly loaned by the American Museum of Natural History, are larger throughout. The fore- arms measure 70-71 mm., against 64-68.4 mm. The Szechwan specimens are much lighter in color, being decidedly brown instead of grayish-brown. The ears and nose-leaves are about the same size as measured on dried specimens. The total length of the skulls of the Szechwan series is 30.5-31 mm., against 29.3-29.6 mm. Most of the added length appears to be in the rostrum. The posterior edge of the nasal notch is broader and more V- shaped, while in the Fukien skulls the edge is narrowed and rounded. It appears that the southern sinensis bears the same relationship to the Szechwan specimens that L. l. caurina And., and Wrought., does to L. l. lyra Geoff., and, as the authors of cawrina said, can only be distinguished by average characters. Lyroderma sinensis was described from two specimens with forearms of 65.5 and 68 mm., and skull lengths of 29.3 and 32 mm. It is not stated in 1Published by permission of the Director, Field Museum of Natural History, Chicago, Illinois. 8—Proc. Bion. Soc. WasH., VOL. 46, 1933. (55) 56 Proceedings of the Biological Society of Washington. the list of measurements which specimen is the type nor is any mention made of the color. Until skulls of the Szechwan series can be compared with the larger of these skulls of sinensis it would not be wise to separate this series on size alone. Also, as it is well known that color varieties exist among many species of bats, a color difference in but two localities would not seem a safe separable character. Rhinolophus rex G. M. Allen. Rhinolophus rex G. M. Allen, Am. Mus. Novitates, No. 85, p. 3, 1923— Wanhsien, Szechwan, China. A female from Tung Wong Tien, Kweichow, almost due south of the type locality, is referred to this species. It equals a topotype of rez in all meas- urements except those given for the horseshoe and sella. These are much lower and narrower, the sella being 6.7 mm. high by 4.2 mm. wide. The topotype was taken in November and this specimen in May so that season might account for the difference in size. ; Triaenops wheeleri Osgood. Triaenops wheeler Osgood, Field Mus. Nat. Hist., Zool. Ser. 18, p. 224, 1932—Muong Moun, Tonkin, French Indo-China. It has seemed advisable to refer three specimens from Tung Wong Tien, Kweichow (40 miles 8. W. of Wen-shui), to this species. The specimens are preserved in alcohol and were so badly shot that but one skull is com- plete enough for study. The skull and wing measurements are both slightly larger than those of the type series but from one specimen, which was dried, the color appears to be the same. More material may show these Chinese specimens to represent a slightly larger subspecies but the present material is not sufficient to characterize them. This is the first record of this genus for China. Ia io Thomas. Ia io Thomas, Ann. Mag. Nat. Hist. (7), 10, p. 164, 1902—South Hupeh, China. A male was collected at Tung Wong Tien, Kweichow, which is about five hundred miles west and a little south of the type locality. The speci- men agrees with the description of the type and about equals it in size. Mr. A. de C. Sowerby (China Journal, 17, no. 6, p. 304, 1932) mentions a second specimen from Nanking but gives no information about the record. This Kweichow specimen appears to be the third to be recorded. Kerivoula depressa Miller. Kerivoula depressa Miller, Proc. Biol. Soc. Wash., 19, p. 64, 1906—Biapo, northeast of Tounghoo, southern Burma. A single specimen taken at Yang Cha Shan, five miles east of Kao-ku- ch’ang, southeastern Szechwan, must be referred to this form. It is larger throughout than the measurements given for the type. A specimen from Muong Mo, Tonkin, is externally equal to the type but has a larger skull than either it or the Kweichow specimen. This appears to be the first published record for this species in China.

The collections reported in this paper were obtained by Mr. Laurence R. Lawler of Lake Charles, chiefly in 1932, or only a few specimens in 1931. These materials are mostly from Lake Charles (1), 32 miles west of Lake Charles (2), 20 miles south- southwest of Lake Charles (8), Prien Lake (4), Caleasieu Lake (5), Calcasieu River at Kinder (6), and 5 miles west (7), 40 miles up stream from Lake Charles (8), Clear Lake at Reeves (9) and the Sabine River at Merryville (10) and 5 miles west (11). They are accompanied by extensive field notes in which a few large species, not represented by specimens, are here included and indicated by an asterisk. Mr. Lawler’s specimens number about 200. Mr. Morrow J. Allen sent me a collection of 85 marine fishes obtained at Breton Island (12), in 1932. These notes are given as including a number of marine species not often met with in fresh water, besides others of interest as locality records. A few specimens were also sent to me by Mr. J. Louis Troemner, obtained at New Orleans (13), October 28, 1929. The numbers following the names of the species pertain to those in parentheses following the localities as given above.

H. RILEY. Sona muse —— : a ant In 1929, I described in these Proceedings, page 162, Niltava smithi, founded upon a single female from the summit of Doi Sutep, Siam. Later the same year de Schauensee? described Niltava williaminae from the same locality, also founded upon a single female. Recently Dr. Hugh M. Smith has sent the U.S. National Museum two adult males and two adult females of Niltava smithi, from Siam, taken at Khun Tan at 4,000 feet. With the acquisition of the males it became at once apparent that the form was closely related to Niltava davidi and possibly was the same as Niltava davidi lychnis of western China. I am indebted to the Museum of Comparative Zoology for the loan of three males and one female of the latter and to the Academy of Natural Sciences, Philadelphia, for forwarding the type of Niltava williaminae, for study in this connection. The males of Niltava smithi are similar to those of N. davidi lychnis, but the black frontal band is narrower, the pileum duller blue, the back duller, duskier blue, the shining blue spot on the sides of the neck is duller, less bright and the size larger. The females of N. smithi and N. davidi lychnis are quite distinct. The female of the latter has the frons and pileum concolor or only a little lighter dresden brown than the back, while in N. smzthz, the frons is narrowly clay color; the feathers of the pileum and nape deep olive-gray at the tip, a little deeper sub-terminally, presenting a somewhat scaled appearance; in N. d. lychnis the mentum is white, followed by a small buffy spot, the cheeks, ear-coverts and sides of throat like the chest, buffy brown, the jugular spot white, while in N. smzthz the lores, chin, throat, ear-coverts, and ocular area are clay color edged or tipped with deep olive-gray, making these areas more or less flammulated, the chest dark olive-buff, the jugular patch deep colonial buff. In N. d. lychnis the belly and under tail-coverts 1Published with permission of the Secretary of the Smithsonian Institution. 2Proceedings Acad. Nat. Sci. Phila., vol. 81, p. 469. 10—Proc. Biot. Soc.

The mantle in N. smithi is buffy brown with a grayish cast and the upper tail-coverts buckthorn brown; in N. d. lychnis the back is dresden brown and the upper tail coverts cinnamon brown. The tail in N. smithi is prouts brown on the middle feathers and on the outer web of the remainder, dusky on the inner web of the outer feathers and the tips of all the feathers, the shafts blackish, while in N. d. lychnis, the tail is cinnamon brown and the shafts of the feathers are the same. The wings in N. smithi are blackish, the feathers only narrowly edged with the color of the back. In N. d. lychnis, they are dusky, the feathers broadly edged with cinnamon. The female of N. smithi and the only female examined of N. davidi lychnis, both lack the light soft blue-violet neck patch of the female of N. sondara, though La Touche* describes the female Niltava davidi davidi as having it. The type of Niltava williaminae, marked as a female, when compared with the three females of N. smithi collected by Dr. Hugh M. Smith, has the pileum more washed with brownish; the back a deeper, more reddish buffy brown without the grayish cast; the upper tail-coverts a deeper, more reddish brown; below the breast and belly are more washed with clay-color and the under tail-coverts deeper buff. While the type does not exactly match any of the three females of N. smithi, I am nevertheless of the opinion that it is only an individual variation of this species, as none of the differences are great. It may be that the type of williaminae is really a young male. A young male of Niltava sondara denotata in the U.S. National Museum shows this same degree of difference when compared with the female of the same form. It remains to say a word concerning the males of N. smithi and N. sondara denotata. In the former the pileum, neck patch, shoulder patch, and rump are a much darker, less shining blue; the back duskier; below the differences are not as great, but denotata is lighter, near raw sienna, while smithi has more of a tawny cast. It seems strange that the males of N. smithi, N. davidi, and N. sondara should be so similar and the females so different, but it is a case similar to that of many species of Cyornis. The specimens measure as follows: 2 oo of Niltava smithi: wing 93.5-100; tail 78-82; culmen 12-13 mm. 3 oo of N. davidi lychnis: wing 88.5-94 (91.2); tail 66-74 (69.8); culmen. 11.5-12 (11.7) mm. 3 22 of N. smithi: wing 92-100 (95.7); tail 68-81 (74); culmen 12-12.5 (12.2) mm. 1 9 of N. d. lychnis: wing 92; tail 62.5; culmen 11 mm.

Indeed, in some ways each of the American species is more like one of the Indian species than it is like its American relative. The distribution, the Punjab, the east coast of southern Mexico, and the west coast of Nicaragua, is quite weird; but the American species have certainly no direct relation- ship with any other American Eumeces. Save for the recently described schmidti from Honduras, which is close enough to fasciatus, schwartzet and managuae are the only New World Eumeces south of the Mexican Plateau. I am somewhat inclined to use Eurylepis Blyth (1854, Journ. Asiatic. Soc.

BY IAN McTAGGART COWAN, Museum of Vertebrate Zoology, University of California. Tee ee roe en ment A study, now in progress, of the deer of the Pacific coast area has revealed the presence of a hitherto unnamed race of mule deer in eastern California. The proposed name, together with the characteristics of the new race, follows. Odocoileus hemionus inyoensis, new subspecies. INYO MULE DEER Type.—Male, adult; skin, skull and skeleton; no. 16363, Mus. Vert. Zool.; “Kid Mountain” at altitude of 11,000 feet, 10 miles west Big Pine, Inyo County, California; October 15, 1911; collected by H. A. Carr, orig. no. 656. Range.—Eastern slope of southern Sierra Nevada, in Owens Valley district of California. Diagnosis.—A medium-sized race of mule deer (measurements of type: total length, 1740 mm., tail, 180 mm., hind foot, 485 mm.). Color (in full winter pelage): Above, in general tone, Cream Buff to Chamois (only capitalized color terms are from Ridgway, Color Standards and Color Nomenclature, 1912); tips of hairs black, producing pepper-and-salt effect usual in any mule deer; dark vertebral stripe originates anteriorly in the dark brow patch and proceeds posteriorly as a narrow median stripe, increasing in width and merging with color of rest of upper parts on rump; brown of back extended mid-dorsally to root of tail, thus interrupting dorsal margin of white rump patch; brow patch yellowish brown with sharply defined black V-shaped mark extending, from point on midline about 2 inches anterior to eyes, midway along eyebrows; face yellowish gray; muzzle whitish except for usual black ring posterior to rhinarium; ears, outside dark gray, inside white; white patch at base of ear restricted; ears not shaggy; black tip of tail as long as white portion; white of inguinal region extending forward in two wedge-shaped areas to within 6 inches of axillae and separated by a narrow posterior projection of gray color of brisket extending back to anterior border of inguinal region; brisket brownish gray; metatarsal gland 4 inches long. Skull short, relatively wide across zygomata and narrow across mastoids, giving appearance of 12—Proc. Biot. Soc. Wasu., VoL. 46, 1933. (69) 70 ~=Proceedings of the Biological Society of Washington. high occiput; that part of squamosal arm of zygoma which forms mandib- ular fossa elevated at outer margin so that posterior part forms angle of 90 degrees with anterior part; lower lachrymal duct larger than upper and piercing rim of orbit anterior to center of rim; nasals relatively broad posteriorly. Comparisons.—From Odocoileus hemionus californicus (Caton), O. h. inyoensis differs in slightly greater average size and predominantly yellowish rather than dusky dorsal surface; crown patch yellowish rather than black with gray flecking; dark vertebral stripe neither so broad nor so well defined. Dark stripe from apex of dark V on forehead, to base of rhinarium, absent; white of inguinal region more extensive; brisket lighter, brownish rather than blackish; skull larger in every part measured save mastoid width which is relatively as well as actually less (mastoid width 97% rather than 104% of orbital width). From Odocoileus hemionus hemionus (Rafinesque), O. h. inyoensis differs as follows: Average size less; general coloration yellower; brow patch yellow rather than gray; ears shorter and much less shaggy, darker behind and with white spot at base more restricted; brisket brown rather than black; inguinal white patch more extensive, projecting up onto breast in two wedge- shaped areas; metatarsal gland shorter, averaging 4 inches in inyoensis as against 5 inches in hemionus. Selected cranial characters in which inyoensis differs from hemionus are as follows: Zygomatic width 59% of basilar length, measured from anterior lip of foramen magnum to posterior margin of incisive foramen, as against 55% in the latter form; palatal width 45% rather than 43% of palatal length; mastoid width 68% rather than 72% of zygomatic width. Remarks.—On point of external appearance, inyoensis shows close ap- proach to representatives of hemionus from northeastern California, but an analysis of the cranial characters indicates the nearest affinity of this race to be with californicus. From both of these races, however, inyoensis can readily be distinguished by the large amount of white on the under- parts and breast, and by the relatively narrower mastoid region. A few specimens of hemionus from Siskiyou County, California, show a tendency to have the white of the abdominal region extended forward onto the breast, but not to such a marked degree as is exhibited by znyoensis. Comparable specimens from Nevada, Colorado, and Placer County, Cali- fornia, show no such tendency. Two juvenile specimens from the type locality, nos. 16361 and 16362, Mus. Vert. Zool., agree with the type in all essentials of coloration, with the exception that the ears are darker outside and in one there is a dark spot at the base of the tail. In making cranial comparisons the average measurements of 6 adult male hemionus from Modoc County, California, and 26 adult male cali- fornicus from Santa Barbara County, California, were used.

Study of the series accumulated in recent years, however, reveals distinguishing characters for this isolated northern colony. My thanks are due to Mr. H. E. Anthony, Curator of Mammals, American Museum of Natural History, for his kindness in loaning the type of S. apache for comparison. The type of Thomomys chrysonotus Grinnell, from Ehrenberg, Arizona, remained unique until 1931 when a fine series of specimens from at or very near the type locality was taken by George Willett for the Los Angeles Museum. Eight of these. specimens, delineating the general range of individual variation, renders it possible to determine more definitely the relationship of chrysonotus to neighboring forms. As a result specimens from the desert plains of southwestern Arizona, hitherto as- signed to chrysonotus, are found to be quite different, and a single example from the Harquahala Mountains presents characters that appear to be quite distinctive. Four new subspecies of Thomomys are here described. For the privilege of studying the topotypes of chrysonotus | am much indebted to Mr. Willett. Sciurus chiricahuae, sp. nov.

WasH., VOL. 46, 1933. (71) ZION, AL W use! i 72 Proceedings of the Biological Society of Washington. National Museum (Biological Survey collection), collected by E. A. Goldman, August 16, 1923. Original number 23527. Distribution.—Known only from the Chiricahua Mountains, Arizona. General characters.—A vividly colored species, with tawny thighs and forearms contrasting strongly with grizzled back. Closely allied to Sciurus apache of the Sierra Madre of Mexico, but color richer, more intense, the fore-limbs, under parts, orbital rings and post-auricular patches near tawny instead of ochraceous buff; cranium more evenly arched in upper outline, the frontal region less flattened anteriorly as viewed from the side. Color.—Type (summer pelage): General dorsal area from top of head to rump a nearly uniform mixture of light ochraceous buff and black producing a grizzled effect, extending well down to a sharp line of demarcation on lower part of sides; limbs and under parts near pure light tawny, contrasting strongly with grizzled general body color; orbital rings, post-auricular patches, tip of nose and lips light tawny like under parts; tail above ochraceous buff mixed with black, the individual hairs tricolored, ochra- ceous buff at base, black on median third, becoming abruptly lighter ochra- ceous buff toward tips; tail below light tawny along broad median line, interrupted by a black zone giving way to broad, light ochraceous buffy marginal areas. In some specimens the outer sides of the thighs are deeper tawny than in the type. Skull.—Very similar to that of S. apache, but shorter and relatively slightly broader; frontal profile more convex across anterior roots of zygo- mata, giving the cranium a more evenly arched upper outline as viewed from the side; nasals shorter, broader anteriorly, the anterior nares opening more widely; dentition about the same. Measurements.—Type: Total length, 552 mm.; tail vertebrae, 275; hind foot (c. u.), 75. Average of ten adults (including type) from Chiricahua Mountains (5,200—-9,000 feet); 544 (580-552); 264 (250-275); 75.5 (73-80). Skull (type).—Greatest length, 63.7; condylobasal length, 58; zygomatic breadth, 38.2; interorbital constriction, 21.5; length of nasals, 21.5; greatest width of nasals anteriorly, 9.8; maxillary toothrow (alveoli), 11.7. . Remarks.—Sciurus chiricahuae and S. apache are obviously very closely allied, but the differences pointed out appear to be trenchant, and in view of their geographic separation by intervening desert plains the two may be treated as specifically distinct. Specimens from the San Luis Mountains, a northern spur of the Sierra Madre extending across the Mexican Boundary in southwestern New Mexico, are referable to apache. Comparison has been made with 38 specimens of apache from various localities within its range, which extends southward at least to El Salto, southern Durango. Specimens examined.—Eleven, all from the Chiricahua Mountains, Arizona. Thomomys fulvus phasma, subsp. nov. TULE DESERT POCKET GOPHER. Type.—From two miles south of Tule Tank, Tule Desert, near Mexican Boundary, Yuma County, Arizona. No. 203026, @ adult, skin and skull, Goldman—New Rodents from Arizona and New Mexico. 73 U. S. National Museum (Biological Survey collection), collected by E. A. Goldman, December 8, 19138. Original number 22355. Distribution.—Lower part of Gila River Valley and desert region of southwestern Arizona, from the Colorado River east at least to Quito- baquito, ranging south into northwestern Sonora. General characters.—One of the palest of the known forms of the genus. Closely allied to and in color about like Thomomys perpallidus albatus of the western side of the Colorado River in California, but smaller and cranial characters distinctive. Similar to Thomomys fulvus chrysonotus of the eastern side of the Colorado River Valley near Ehrenberg, Arizona, but paler, less yellowish, and audital bullae decidedly smaller. Differing from Thomomys fulvus cervinus and Thomomys fulvus modicus, its geographic neighbors on the east, by pallid coloration and combination of skull characters. Color.—Type (acquiring summer pelage): Upper parts between pale pinkish buff and pinkish buff (Ridgway, 1912), scarcely modified by dark- tipped hairs, except for a fine admixture on face, top of head, and median dorsal area, passing gradually into white along lower part of sides; under parts overlaid with white, the light plumbeous basal color showing through except on chin and inner sides of forearms; muzzle dusky; ears blackish; black post-auricular spots small; limbs and tail white. In some specimens the black post-auricular spots are scarcely discernible and the under parts are nearly pure white to roots of hairs. One example from Tule Wells, near the type locality is darker, or more pinkish buff than usual, while another from the same place and in the same winter pelage exhibits the pallor normal in the subspecies. Skull.—Closely resembling that of T. p. albatus, but smaller, less angular, more smoothly rounded; braincase usually narrower; upper outline more evenly curved as viewed from the side (tending to bulge upward more prominently across anterior roots of zygomata in the older adults of both sexes in albatus); nasals shorter; incisors narrower. Smaller than that of T. f. chrysonotus, with shorter nasals; bullae smaller, less bulging below level of basioccipital; incisors much narrower. Still more decidedly smaller than that of 7. f. cervinus, and differing otherwise in about the same charac- ters as from chrysonotus, except the audital bullae which are relatively about the same. Compared with that of T. f. modicus the skull is relatively shorter, broader, and more flattened; nasals shorter; audital bullae similar; incisors slightly narrower. Measurements.—Type: Total length, 199; tail vertebrae, 66; hind foot (c. u.), 29. An adult female topotype: 195; 68; 29.5. Skull (type): Condy- lobasal length, 34.1; zygomatic breadth, 22; greatest breadth across squamosals (over mastoids), 18.9; interorbital constriction, 6.3; length of nasals, 11; maxillary toothrow (alveoli), 7.7; width of upper incisors (cutting edge), 3.8. Remarks.—In describing new pocket gophers from Arizona (Journ. Washington Acad. Sci., vol. 21, no. 17, pp. 416-417, Oct. 19, 1931), I pointed out the close affinity of the pocket gophers inhabiting the eastern and western sides of the lower course of the Colorado River. This was —— 74 Proceedings of the Biological Society of Washington. regarded as due to the shifting channels and the probable transfer of colonies from one side to the other from time to time. While animals from near the delta on the opposing sides are nearly identical in color and differ only slightly in combination of cranial characters progressive divergence is shown in series from more distant points. Specimens from Quitobaquito are darker and apparently grade toward modicus in color, but the skulls are about like those of typical phasma. Specimens examined.—Total number, 38, as follows: Arizona: Colorado River (at Mexican Boundary Monument 204), 1; Gadsden, 7; Somerton, 1; Quitobaquito, 2; Tacna, 1; Tule Tank (type locality), 3; Tule Well (near type locality), 2; Yuma, 11; Yuma (18 miles south), 7.

HARQUAHALA MOUNTAIN POCKET GOPHER. Type.—From Harquahala Mountains, Yuma County, Arizona (altitude 3,000 feet). No. 227803, @ adult, skin and skull, U. 8. National Museum (Biological Survey collection), collected by E. A. Goldman, October 14, 1917. Original number 23356. Distribution.—Known only from the Harquahala Mountains, but may inhabit other desert ranges of western Arizona. General characters.—A very small, rather pale form with a weakly- developed skull. Most closely allied to Thomomys fulvus desertorum of the Detrital Valley region of northwestern Arizona, but smaller and paler, more cinnamon buffy (near tawny or ochraceous tawny) in desertorum, with a more slender skull. Much smaller and paler than 7’. f. fulvus of San Francisco Mountain. Darker and contrasting strongly in delicate structure with its geographic neighbors, 7’. f. chrysonotus and T. f. flavidus, of the Colorado River Valley. Color.—Type (acquiring fresh pelage): Upper parts near cinnamon brown, purest on cheeks, shoulders, and sides, finely and rather incon- spicuously mixed with black along median dorsal area; small patches of worn pelage on posterior part of back near cinnamon in tone; face and top of head darker, the dusky hairs more numerous; under parts, forearms, and thighs pinkish buff; muzzle dusky; ears and small post-auricular areas deep black; feet and tail whitish. Skull.—Small, slender and delicate in structure, with a narrow but high and rounded braincase. Rather closely resembling those of T. f. fulvus, and 7. f. desertorum but smaller, with a narrower, relatively more highly arched, more smoothly rounded braincase; zygomata more slender, almost thread-like; audital bullae rather small, but fully inflated as in desertorum; dentition light. The skull is similar to those of 7. f. chrysonotus and T. f. flavidus in general form, but differs so widely in diminutive size that close comparison is not required. Measurements.—Type: Total length, 183; tail vertebrae, 60; hind foot Goldman—New Rodents from Arizona and New Mexico. 75 (c. u.), 25. Skull (type): Condylobasal length, 30.8; zygomatic breadth, 19.2; greatest breadth across squamosals (over mastoids), 16; interorbital constriction, 6.5; length of nasals, 10.2; maxillary toothrow (alveoli), 6.8; width of upper incisors (cutting edge), 3.2 Remarks.—With some hesitation a new subspecies is proposed on the basis of a single female specimen. ‘The characters presented, however, appear to be well beyond the range of individual variation in the neighbor- ing forms, and adult males may be expected to reveal more distinctive features. The new form may prove to have an extensive range in the desert mountains of the general region. Thomomys fulvus mutabilis, subsp. nov. VERDE VALLEY POCKET GOPHER. Type.—From Camp Verde, Yavapai County, Arizona (altitude 3,200 feet). No. 214611, & adult, skin and skull, U. 8. National Museum (Biological Survey collection), collected by Walter P. Taylor, July 25, 1916. Original number 269. Distribution.—Valleys and lower slopes of mountains in the Gila River drainage along the southern side of the Mogollon Plateau, Arizona, ranging mainly in Lower Sonoran Zone. General characters—A medium-sized, cinnamon buffy subspecies. Closely allied to Thomomys fulvus fuluus of San Francisco Mountain, Arizona, but color distinctly more cinnamon buffy, instead of cinnamon (Ridgway, 1912), the upper parts less mixed with black, and skull more massive. Probably intergrading with 7. f. cervinus of the Salt River Valley near Phoenix, but smaller and color rich cinnamon buff, instead of dull pinkish buff. Similar in color to T. f. desertorwm of Detrital Valley, north- western Arizona, but usually darker, and skull larger, more massive. Differing from 7’. f. toltecus of northwestern Chihuahua mainly in smaller, less massive skull; color usually somewhat brighter, more cinnamon buffy. Color.—Type (acquiring fresh pelage): Upper parts near cinnamon buff with a light tawny admixture, purest along sides, the top of head and median dorsal area somewhat obscured by dark-tipped hairs; muzzle blackish; ears and small but sharply defined post-auricular areas deep black; under parts, forearms, and thighs cinnamon buff; feet whitish; tail light brownish above on basal two-thirds, lighter below, becoming whitish all around toward tip. Topotypes varying in tone from cinnamon buff to near tawny. Skull.—Very similar to that of 7. f. fulvus but heavier; basicranial region usually decidedly broader; audital bullae larger. Resembling that of T. f. desertorum, but larger and more massive. Similar to those of T. f. cervinus and T. f. toltecus, but smaller than either, with relatively smaller audital bullae. Measurements.—Type: Total length, 236; tail vertebrae, 71; hind foot, 31. Average of seven adult female topotypes: 216 (203-228); 68 (64-73); 29 (27.5-30.5).

Remarks.—Thomomys f. mutabilis ranges in the valleys and along the lower southern slopes of the Mogollon Plateau from the Verde River east to near the New Mexican Boundary. Specimens vary slightly from locality to locality, as usual in the group. The region of the type locality is inter- mediate in geographic position and specimens from it tend to bridge the gap between 7’. f. fulvus and 7. f. cervinus, but differ too widely to be properly referred to either. Specimens from Safford in the upper part of the Gila River Valley are somewhat larger and apparently grade toward T. f. toltecus. Specimens examined.—Total number, 44, all from Arizona as follows: Camp Verde (type locality), 21; Cazador Spring (south base of Nantan Plateau), 1; H-bar Ranch (10 miles south of Payson), 2; Montezuma Well (near Camp Verde), 3; Rice, 6; Safford, 9; Turkey Creek, Yavapai County, 2. Thomomys fulvus emotus, subsp. nov. ANIMAS MOUNTAIN POCKET GOPHER. Type.—From Animas Peak, Animas Mountains, Hidalgo County, southwestern New Mexico (altitude 8,000 feet). No. 157005, o& adult, skin and skull, U. S. National Museum (Biological Survey collection), collected by E. A. Goldman, August 3, 1908. Original number 19929. Distribution. Known only from the upper slopes (7,000-8,000 feet) of the Animas Mountains, New Mexico. General characters.—A small, dark brown subspecies, with a short, broad skull; upper incisors curving directly downward (not projecting forward beyond anterior plane of nasals). Similar to Thomomys fulvus collinus of the Chiricahua Mountains but smaller and color darker cinnamon; skull smaller and differing in detail. Closely resembling Thomomys fulvus intermedius of the Huachuca Mountains, and Thomomys burti of the Santa Rita Mountains but color brighter, more uniform cinnamon brownish, without a well-defined black median dorsal area, and skull shorter than in either. Differing from Thomomys mearnsi of the Animas Valley and lower slopes of the Animas Mountains, in decidedly darker color and cranial details, especially the more strongly decurved upper incisors. Color —Type (worn summer pelage): Upper parts near cinnamon brown (Ridgway, 1912), somewhat lighter, and nearer cinnamon along lower part of sides; middle of back dusky, owing apparently to wearing away of cinnamon brown tips of hairs; muzzle, face, and top of head blackish; under parts overlaid with cinnamon, the under color of pelage dark plumbeous nearly everywhere; a small, irregular, pure white spot (without special significance) on middle of breast, and one on each wrist; ears and auricular spots deep black; forearms and thighs cinnamon; feet and tail dull whitish. A topotype is nearly identical in color. Skull.—Cranium small, short, and light in structure, with strongly decurved upper incisors. Similar to that of 7. c. collinus, but decidedly smaller, less angular; braincase more smoothly rounded; temporal ridges Goldman—New Rodents from Arizona and New Mexico. 77 more widely separated and lambdoid crest less prominent in mature males; interorbital region less constricted; dentition rather light; upper incisors more decurved than in the type of collinus. Differing from that of T. mearnst in about the same characters as from collinus, except that the upper incisors contrast still more markedly in directly downward curvature (upper incisors inclined strongly forward and projecting beyond anterior plane of nasals in mearnsi). Approaching in size and closely resembling that of the geographically isolated form, 7. burti, but somewhat shorter and slightly flatter, the upper outline apparently straighter; rostrum slightly shallower; nasals narrow and deeply emarginate posteriorly as in burti, and dentition about the same. Measuremenis.—Type: Total length, 202; tail vertebrae, 60; hind foot, 26. An adult male topotype: 197; 55; 27. Skull (type): Condylobasal length, 34.6; zygomatic breadth anteriorly (zygoma broken posteriorly), 21.2; greatest breadth across squamosals (over mastoids), 17.5; interorbital constriction, 7.2; length of nasals, 12.5; maxillary toothrow (alveoli), 7.2; width of upper incisors (cutting edge), 4. Remarks.—Specimens of the present form were assigned by Bailey (North Amer. Fauna, no. 39, p. 85, Nov. 15, 1915) to T. f. intermedius. The collection of additional material in southern Arizona has, however, indicated that intermedius must be accorded a more restricted range, and that several closely allied forms inhabiting the upper slopes of high moun- tains in the general region present distinctive characters and warrant separate recognition. Intergradation with 7. mearnsi, which occurs from 5,000 feet on the open plains of Animas Valley up to 5,800 feet on the lower slopes of the Animas Range, is not definitely shown but is strongly suggested by general comparisons. Specimens examined.—Three (including type), all from near the top of the Animas Mountains, New Mexico. — ——— ——— AED ee cwi\t i ao Rk Pan ue fh Lae Bld 4 1 iv Md wis} wa Vist dit i Ait ( \ ia } i ie ey ‘ Hy! ay 1 y uh i}, ' pe Wha ties Lois saat msTo or Sy A bl LN ees Y Vo CLL ANAC ’ a a st nrg ' jay yy Frit 5 i ‘ hy i a; \ . wd brs i i wah re 1 4 \ i A , ‘ ‘ ‘ i iy by * af ; , yi ‘ Ae UY i l* vy 4 i ’ ‘ ‘ / \ ih i ad t i ¥ we ie ; woe \ ran J ty BT vAe a if ‘ isi i : | Vol. 46, pp. 79-82 April 27, 1933 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON ~ | AZ fk OY 2 \\ ys NUD hn fed J YA FIVE NEW SHREWS OF THE GENUS?, onyproris si FROM MEXICO AND GUATEMAEA>—— BY HARTLEY H.

Type in the U. S. National Herbarium, no. 1,283,260, collected at Rio Frio, Quebrada Rodriguez, Santa Marta, Colombia, Mar. 15, 1925, by Fred Walker (no. 1211). Four species of Hiraea have been reported to occur in Santa Marta, viz: H. reclinata Jacq., H. velutina Ndzu., H. transiens Ndzu., and H. opulifolia (Rusby) Ndzu. The first of these differs from Hiraea sanctae-marthae in its more coriaceous leaves, which are nearly glabrous beneath except on the midvein, and in its larger flowers. H. velutina is more closely related, differing in its velutinous-tomentose under leaf-surface (rather than silvery-sericeous) and in its stipules, which are borne considerably above the base of the petiole. The Santa Marta record for this species is based on H. H. Smith 1514. The sheet of this number in the U. S. National Herbarium is a mixture of perhaps three species, probably none of which is H. velutina. The largest specimen is quite typical Hiraea sanctae-marthae. H. transiens has glabrate leaves and long petioles stipulate near the apex. The remaining species, Hiraea opulifolia, is known to me from description only, but it must be quite unrelated to the group of species here discussed. Hiraea colombiana Morton, sp. nov. Subg.

Type in the U.S. National Herbarium, no. 1,517,269, collected at the edge of woods near Loso, north of Toledo, Eastern Cordillera, Dept. Norte de Santander, Colombia, alt. 2,200—2,400 meters, Mar. 6-7, 1927, by E. P. Killip and A. C. Smith (no. 20474). A second specimen is mounted ° on sheet no. 1,355,512. The fruit is described from a second collection, this also from the Eastern Cordillera, in thickets along stream on the road from Pamplona to Toledo, crossing the divide between Rio La Teja (Maracaibo drainage) and Rio Mesme (Orinoco drainage), Dept. Norte de Santander, Colombia, February 28, 1927, by Killip and Smith (no. 19824). The small subgenus Archthiraea contains only four members: H. spruce- ana, H. brachyptera, H. brachypoda, and the present species. The only one to which H. colombiana is related is H. spruceana, described from the Rio Chasuan, on Chimborazo, Ecuador (Spruce 6152), which differs in its golden tomentose young twigs and lower leaf-surfaces, obovate larger leaves (merely rounded at base), and longer petioles, these bearing a pair of stipules near the base. Furthermore, the calyx is 8- (not 10-) glandular and the flowers in an umbel are more numerous.

SNYDER, ~———— Senior Entomologist, Bureau of Entomology, United States Department of Agriculture. A small collection of termites received from J. C. M. Gardner, systematic entomologist, Forest Research Institute, Dehra Dun, India, contains two new species that are not included among those mentioned in another paper of mine, now in press, on new termites from India. These two new species, described herewith, give India a total of 86 known termites; in continental United States there are 56 known species. One of these species is in the subgenus Huhamitermes Holmg., genus Amitermes Silv., represented by hamatus Holmg. from Malacca and indicus Holmg. from India, and known only from the soldier caste; these termites are very rare and only one colony of each has been found. The other new species is in the genus Microtermes Wasm. and may be the sexual form of a species known only from the soldier caste, although it is very different from any known sexual form. Both new species were found in a mound nest of Termes (Cyclotermes) obesus Ramb. The king and queen of the new Microtermes were in a cell about 11% feet above the ground level. It is not known from what part of the nest the soldier of the new Euhamitermes was found. The king and queen of the host termite, a common fungus- growing species, were also collected. There is a marked con- trast between the Termes and Microtermes queens. The obesus queen is an old, physogastric, macropterous female, 68 mm. in length and 17 mm. in width. The usual dark, longitudinal streak runs down the middle of the dorsal area, as is character- istic of old obesws queens. In older and larger queens (over 18—Proc. Biou. Soc. WasH., VOL. 46, 1933. (91) 92 Proceedings of the Biological Society of Washington. 100 mm. in length and 25 mm. in width) of African termites in the Termes group, this blackish area is not present. Such queens are over 160 times the size of the king, as determined by volu- metric displacement, whereas this obesws queen has only 75 times the volume of the king. Descriptions of the new species follow: Microtermes unicolor, n. sp. King (slightly physogastric, dealated male)—Head castaneous brown, with dense long hairs, the bases of which appear as white dots. Post-clypeus yellow, strongly bulging and bilobed, length about half its width. Labrum yellow, tongue-shaped. Fontanelle a raised white spot at the convergence of the lines from the ocelli to the vertex, namely, at the beginning of the epicranial suture. Eyes black, large (small in stndensis Desn.), projecting, not round, very close to lateral margin of head. Ocelli white, large, suboval, separated from eyes by a distance less than half the short diameter of ocellus and at an oblique angle to eyes. Antennae with 13 segments (broken?), second slightly longer than third and fourth segments, which are subequal. Pronotum of about the same color as the head and with the same pu- bescence; subcordate; sharply and deeply, but narrowly, emarginate an- teriorly; shallowly and angularly emarginate posteriorly with a T-shaped or shallow Y-shaped white median marking and an ocellus-like marking on the upper corner of each lobe. Anterior wing scale slightly longer than posterior. Meso- and meta-nota slightly lighter colored than pronotum; unlike in obesi Holmg., the fore part of the meso- and the meta-notum is lighter colored than the hind part; the mesonotum is more deeply incised posteriorly than the metanotum. The meso- and meta-thoracic legs are missing on the left side, and there is a black bite scar on the mesothoracic coxa.

The head of lighti is larger than that of hamatus and the dentition of the left mandible appears to be different; the pilosity appears to be similar, but the cotype is in poor condition. The head of lighti is shorter and broader than that of indicus, and indicus does not have the rather thick mat of short hairs in addition to the longer bristles. A. indicus has a very few short hairs. There are differences in the size of the head and lighti has a wider gula; cotype of zndzcus in poor condition. Named in honor of Dr. S8. F.

BY EDWARD A. CHAPIN, Taxonomic Investigations, U. S. Department of Agriculture. Recently Dr. George N. Wolcott of the Insular Experiment Station, Rio Piedras, Puerto Rico, submitted a series of adult specimens of a coccinellid which had been reared from larvae found attacking Icerya purchasi Mask. at Dorado, Puerto Rico. At the same time larvae were submitted to Dr. A. G. Boving, who will describe them in a subsequent paper. At first glance the species appears to be related to Rodolia Muls., and further, its anatomical characters are not in accord with those of the species of Scymnus known to the writer in dissected specimens. However, since Dr. Boving’s study showed the larva to be undoubtedly scymnine in its affinities, certain of the West Indian species were studied as dissections in balsam. It is now evident that a small group of species inhabiting this region should be withdrawn from Diomus Muls. and be given a separate name. Diomus thoracicus Fabr., type of the genus Diomus, and other species including D. rosezcollis Muls. of the West Indies, possess antennae of eleven segments (fig. 2) and tarsi of four segments (fig. 1). The new group, to which I assign the name Decadi- omus, is immediately distinguished from Dizomus by having ten-segmented antennae (fig. 4) and three-segmented tarsi (fig. 3). In addition to the type species, Scymnus (Diomus) bahamicus Casey 1899, there are four species before the writer, all of which appear to be undescribed. 19—Proc. Bron. Soc. WasH., Vou. 46, 1933.

Small to minute Scymnini, with antennae short, composed of ten seg- ments, first segment more or less inflated, second globose, third as long as the three succeeding combined, seventh a little longer and wider than sixth, eighth to tenth forming a distinct club. Mandible with apex bifid, outer margin arcuate, basal tooth subacute, notch triangular to rectangular, cutting edge between apical tooth and notch very finely serrate or smooth. Maxilla with lacinia and galea, neither of which is terminated with a spinous or hook-like process, maxillary palpus of usual form, terminal segment securiform, without special sensory pits or spines on outer face. Ligula truncate at apex, bearing four long setae evenly spaced across truncature, lateral portions thickly studded with denticles. Labial palpus two-seg- mented, the apical segment obtusely conical, shorter and narrower than basal segment. Clypeus broadly rounded. Epistoma slightly prolonged. Pronotum narrower at base than elytra. Elytra with epipleura moderately wide at base, strongly narrowed apically, without impressions to receive legs. Abdomen with six visible ventral segments. Metacoxal arcs joining posterior margin of first sternite at lateral thirds.

Body small, elliptical to nearly circular, flesh-pink to red, ornamented with piceous to black markings. Head somewhat shining, very finely and rather sparsely punctured, uniformly pale. Eyes large and prominent, though partially concealed beneath anterior angles of pronotum. Pro- notum transverse, sides narrowly rounded, slightly narrower across anterior than across posterior angles, surface finely and sparsely punctured, feebly shining, uniformly pale. Scutellum pale. Elytra more strongly and distinctly punctured, humeral callus prominent and shining. Each elytron bears two dark spots, one at the base lying between the humeral callus and the scutellum and extending backward about one fifth the length of the elytron, the pair of spots (on the two elytra) usually flowing together to form a cordate spot, the apex of which lies on the suture at about the basal third. The second spot, slightly postmedian, is roughly circular or elliptical with the long dimension parallel to the long dimension of the beetle. Rarely does this pair of spots join across the suture. Under parts feebly shining. Metathorax sometimes infuscate, first abdominal sternite as long as second and third combined, suture between first and second distinct. Length 1.6 mm., breadth 1.1 mm., altitude 0.6 mm. (measurements of type specimen). Type and five paratypes (U.S. N. M. Cat. No. 44714), one of which is 98 Proceedings of the Biological Society of Washington. mounted on slide in euparol, from Dorado, Puerto Rico, collected as larvae July 11, 1932, and reared by Mr. Sein. The larvae were found feeding on Icerya purchasi Mas. Three paratypes, same data, returned to Doctor Wolcott. Decadiomus hubbardi n. sp. Fig. 7. Body small, oval, yellow-testaceous, ornamented with three piceous spots. Head strongly shining, sparsely and rather coarsely punctured, eyes prominent. Pronotum transverse, sides straight and convergent from the obtuse posterior angles to the broadly rounded anterior angles, surface shining, rather sparsely punctured at sides, more sparsely so on disc. Scutellum pale. Elytra shining, distinctly but not deeply punc- tured, humeral callus not especially prominent. Maculation as follows: A large cordate scutellar spot reaching to middle of base of each elytron and posteriorly to near basal third of suture, and on each elytron a small nearly circular spot near apical third at middle of width. Under parts shining, thorax not visibly punctured, abdominal sternites moderately coarsely punctured, first and second sternites combined as long as rest of abdomen, suture between first and second not visible. Length 1.32 mm., breadth 0.9 mm., altitude 0.6 mm. Type: (U. S. N. M. Cat. No. 44728) from Montserrat, W. I., Apr. 8, 1894, H. G. Hubbard. Decadiomus tricuspis n. sp. Fig. 5. Body small, oval, very pale stramineous (almost white), ornamented with piceous to almost black markings. Head shining, not visibly punc- tured, eyes prominent, black. Pronotum transverse, sides narrowly rounded to both anterior and posterior angles, surface shining, not visibly punc- tured, basal margin on either side of scutellum with small dark spot ad- jacent to basal elytral spot. Scutellum dark. LElytra shining, coarsely and sparsely punctured, submarginal groove with about ten coarse punc- tures along middle third of length, epipleura descending. Maculation as follows: A large basal spot which includes the scutellum and which is roughly seven-angulate; basally two angular processes extend onto the pronotum, laterally one process to each humeral callus, posteriorly a long median process along suture to a little beyond basal third, flanked on either side by a shorter process. On apical half, each elytron with a single subtriangular spot which appears to be a continuation of the posterolateral process of the basal spot. Underparts pale, first sternite almost as long as next three combined, suture between first and second distinct. Length 1 mm., breadth 0.66 mm., altitude 0.48 mm. Type and two paratypes (U. 8. N. M. Cat. No. 44726) from Rio Piedras, Puerto Rico, January 21, 1925, H. L. Dozier, collected on Carica papaya, feeding on Metaleurodicus sp. Proc. Brot. Soc. WasH., Vou. 46. Puate I. Chapin—A New Genus of West Indian Coccinellidae. 99 Decadiomus peltatus n. sp. Figs. 8, 9. Body small, oval, pale stramineous, ornamented with a single dark scutellar spot. Head shining, not visibly punctured, eyes prominent, black. Pronotum transverse, sides feebly rounded and strongly convergent anteriorly, angles very narrowly rounded. Scutellum dark. Elytra moder- ately shining, coarsely and sparsely punctured, submarginal groove without coarse punctures, epipleura descending. Color pale, with a dark spot which varies considerably in size. In its greatest development this spot extends along the bases of the elytra nearly to the humeral calli; its great- est width is at the basal fourth, where it is as wide as the distance across the humeri. From this point its margin runs obliquely backward to a point near the suture and at apical third of the length, turning thence to the suture. At about the middle of the length and near the suture each elytron bears a small pale spot. In its least development this spot occupies roughly the sutural third of the basal third of each elytron. Underparts pale, first and second sternites together as long as rest of abdomen, suture between first and second absent across middle. Length 1.08 mm, breadth 0.7 mm., altitude 0.5 mm.

BOVING, Neer ace “a U.S. Bureau of Entomology, Washington, D. C. Three larvae of the coccinellid species Decadiomus pictus Chapin were received from Dr. George N. Wolcott, Isabella, Puerto Rico, together with pupae and adults reared from identic larvae. Dr. Wolcott states that this lady beetle was found attacking the cottony cushion scale on Casuarina and Citrus on Miss Livingstone’s place, Dorado, Puerto Rico. Larvae were collected by F. Sein and George N. Wolcott and reared to adults July 11, 1932; additional specimens of larvae and pupae were secured on September 12, 1932. This coccinellid beetle represents, according to Dr. KE. A. Chapin, who has described. and figured the adult, a new genus and new species of the tribe Scymnini. Decadiomus pictus Chapin. (U.S. National Museum; one vial with one larva, one vial with two pupae, and two glass slides with anatomical details of two larvae and one larval skin; specimens marked: “‘Decadiomus pictus Chapin; new genus, new species, P.

Wolcott, Isabella, Puerto Rico dedit.’’) The full-grown larva (figs. 4 and 5) is about 3 mm. long, sub-ovate in outline, tapering forward from metathorax and backward from the sixth abdominal segment, dorsally arched, ventrally rather flat; the tenth abdominal segment is bent downward forming a well developed locomotive sucker. The specimen preserved in alcohol shows the prothorax dorsally light, the head and the entire medio-dorsal part of the rest of the body between the alar areas darker, the lateral and ventral parts light, and the 20—Proc. Biot. Soc. WassH., VoL. 46, 1933, (101) 102 Proceedings of the Biological Society of Washington. legs light. The whole larva is concealed under a thick coat of white, woolly wax threads. The cranium (figs. 4 and 9) (stretched out horizontally in the figures to show its form and proportion to the body) is in its natural position bent downward and its posterior margin is covered by the fleshy anterior part of the prothorax. It is about twice as broad as long, subrectangular with rounded anterior and posterior corners, darkly pigmented, and with the region in which the ocelli are seated darker than the rest. The labrum (fig. 9) is almost perpendicular, broad with arched surface, and covers the flexed mandibles like an eye shade. Its anterior margin is slightly trilobed, and laterally it is somewhat sclerotized. There are a series of six long setae near the posterior margin and two pairs of smaller setae anteriorly. The clypeus is not distinct, no epistomal sclerome being developed. The frons is completely fused with the epicranium, and neither frontal nor epicranial sutures are present. There are three large ocelli on each side, arranged in a triangle just behind the antennal foramen. The antenna (fig. 1) is considerably shorter than the mandible, broadly conical, and attached by a large basal membrane; there are only two anten- nal joints; the proximal of these is probably composed of the fused basal and second joints of other coccinellid larvae (I+II fig. 1) as it carries a puncture, the landmark of the basal joint, at its posterior margin, and also two setae, the landmark of the second joint, at its anterior margin; the apical joint (III fig. 1) is minute, externally inserted in the membranous top of the proximal joint, and carries a long seta; a tactile filament extending as far as the end of this seta projects from this same membrane on the inner side of the antenna. The mandibles (fig. 2) are symmetrical, falciform with a simple, strongly bent, acutely pointed apex; the inner margin of each is somewhat sulcate; the lacinia mandibularis is triangular, fairly large, and membranous; a mola-like enlargement is present and particularly hard and dark on the buccal margin toward the well developed hypopharyngeal sclerome, with which it links closely. The maxillae (fig. 7) are deeply retracted, large, fleshy, and fused with the labium almost for their entire length. The cardo is indistinct, with a splinter-like sclerome (ca, fig. 7). The stipes is large, posteriorly fused with the cardo, and membranous except anteriorly where the margin is marked by a thin sclerome that is somewhat triangularly enlarged in the corner toward the labium and from here prolonged into a pair of fine rods for the support of the inner face of the maxillary mala (fig. 10). The mala is an entire, large, obtusely rounded, membranous, and whitish lobe covered proximally on the ventral surface by a thin, dark plate in which three long setae are inserted; distally, and mainly on the dorsal surface, are three small cylindrical pegs and one larger tactile projection. The palpiger is rather large and entirely membranous. The maxillary palpus is stout and conical; it consists of only three distinct joints, the subapical joint, nor- mally present in other coccinellid larvae, being eliminated and merely indicated by the long seta that characterizes it; the prebasal joint has the Proc.

The labium (fig. 7), only apically free, is large and fleshy, with submen- tum, mentum, and prementum completely fused. The labial palpus is distinctly two-jointed, with a short, wide, basal joint and a long, conical, apical joint terminally provided with tactile papillae. The ligula is in- distinct. The body (fig. 4) is entirely without scleromes or setae bearing verrucae. Dorsally and laterally the segments are covered densely with minute pointed papillae. There are many rather short, fine, soft, and irregularly distributed setae, and several cylindrical, peg-like organs with curved, obtuse, clear ends (cyl. p., fig. 4). Dorsally on each side of the mesothorax and meta- thorax is a long, exteriorly curved, secretory slit garnished with a row of long, stiff, pointed setae, and dorsally on the abdominal segments are many circular secretory spots (ss, fig. 6). In the skin between the meta- thorax and the first abdominal segment, and between the rest of the abdominal segments, except the last two, are found large, spindle shaped foveae (fo, fig. 6), which secrete bloodlike fluid (haemorrhée or blood secretion). The spiracles are small, circular, and belong to the annular type; they occur on the mesothorax and the first eight abdominal segments. The spiracular tracheae are provided with double-armed closing apparatus (fig. 8) situated comparatively far inside of the spiracles. The legs (fig. 3) are well developed, lightly sclerotized, and of about equal length. They articulate with thin riblike episternal and epimeral scleromes. Each leg consists of a large, obliquely inserted coxa, a distinct trochanter, a somewhat cylindrical femur, about as long as, but more slender than coxa, a slightly longer and slender tibio-tarsal piece,! that tapers toward the ungulus.! This latter is short, curved, with a broad base and long point. It is surrounded by five long, capitate bristles from the end of the tibio-tarsus, and itself carries a short seta at the base of its concave inner side. The setae on the other parts of the leg are few and of average length. Of particular interest are their number and arrangement on the tibia-tarsus where, besides the already mentioned five capitate, terminal setae, there are three equidistant normal setae on the exterior face and three on the interior face; in no case are the setal cups carried on top of small tubercles. It has not been found necessary to offer a full description of the propor- tional dimensions, the pigmentation, and the whole chaetotaxy of the cranium, mouth parts, body, and legs, as these details are shown on the 1In substituting the term “‘tibio-tarsus”’ for the term “‘tibia,’’ formerly applied by me, and “‘ungulus”’ instead of ‘‘clawshaped tarsus,’’ I am following Grandi, who has used these terms for many years, for instance, in his ‘‘ Descrizione di un nuovo Coccinellide africano, Serangium giffardi n. sp., 1914.’”’ In so doing, I have been influenced by Snodgrass’s thorough studies of the scleromes and muscular structures of the legs in insects.

The type specimen of Dicksonia Pearcet Baker, at Kew, consists of two smallish fronds (without rhizome) collected in the ‘eastern Andes of Ecuador, at 8,000—9,000 ft.” by Pearce (no. 251) and presented by Messrs. Veitch in 1884. It agrees with type material of Loxsomopsis Lehmannii from Ecuador (Lehmann 506), and the earlier species name must accordingly have precedence, under Loxsomopsis. GLEICHENIACEAE. Dicranopteris pallescens (Mett.) Maxon. Gleichenia pallescens Mett. Ann. Sci. Nat. V. Bot. 2: 267. 1864. Founded on Lindig 273, from Velez, Colombia, of which I have seen an isotype at Kew. Here is to be referred, without doubt, a recent collection by William Seifriz (no. 60), from ‘‘ Cincinnati,” on the lower slopes of Mount San Lorenzo, near Santa Marta, Colombia, alt. 1,300 meters. This is a well-developed plant, somewhat larger than the immature Lindig specimen. . The under surface is subglaucous merely, like the varietal form mentioned by Mettenius. The segments are 2 to 3 mm. broad, the larger ones 3 to 3.5 em. long. POLY PODIACEAE. Elaphoglossum Hayesii (Mett.) Maxon. Acrostichum Hayesvi Mett.; Kuhn, Linnaea 36: 43. 1869.

It is a member of the difficult and variable group of FZ. piloselloides (Presl) Moore. Polypodium phlegmaria J. Sm. London Journ. Bot. 1: 194. 1842. Polypodium tovarense Klotzsch, Linnaea 20: 374. 1847. Polypodium phlegmaria was founded on Schomburgk 161, from British Guiana; P. tovarense on Moritz 251, from Tovar, Venezuela. The latter has been reduced to synonymy under P. phlegmaria by Christensen, and a comparison of Moritz 251 with the type specimen of P. phlegmaria (both at the British Museum) shows that this disposition is correct. The follow- ing additional specimens are in the National Herbarium: Near Santa Rosa, Dept. Antioquia, Colombia, alt. 1,700-2,000 meters, Lehmann 7589; upper slopes of Mount Roraima, 7m Thurn 179. These plants agree closely. The rhizomes bear abundant scales at apex, and the rigidly spongiose fronds are glabrous. At Kew the two British Guiana collections (Schomburgk 161 and im Thurn 179) are mounted on the same sheet, and are identical. Both, how- ever, are annotated by Baker as P. tovarense, notwithstanding that P. phlegmaria (type, Schomburgk 161) has five years’ priority. Hieronymus also has identified? the Colombian collection above cited (Lehmann 7589) as P. tovarense, making no reference whatever to P. phlegmaria. Since both Baker and Hieronymus failed to adopt the earlier name the writer remained in doubt as to the correctness of Christensen’s treatment, until (in 1930) he was able to examine Moritz 251. The name tovarense was then found to apply without doubt to P. phlegmaria rather than to the next species, which superficially is similar. Polypodium Alfarii Donn. Sm. Bot. Gaz. 33: 262. 1902. Polypodiwm oligosorum Moritz, Bot. Zeit. 12: 855. 1854, nomen nudum; Mett. ex Kuhn, Linnaea 36: 132. 1869. Not P. oligosorum Klotzsch, 1847. The present species, though indicated by Moritz as new (under the name P. monosorum Moritz) on the basis of Moritz 460, was first actually de- scribed as P. oligosorum Mett., three collections from Venezuela being cited, viz. Moritz 460, Fendler 208, Karsten 10, of which the first may be regarded as the type. The name oligosorwm itself is invalid, as shown above. Agreeing with Moritz 460, however, there are at hand numerous Costa Rica and Panama specimens (previously identified by the writer as P. Alfariz) and two additional South American specimens. It is apparent that the name P. Alfarzi must be used for the whole series. In general appearance P. Alfarii somewhat suggests P. phlegmaria (P. tovarense), with which it grows in at least one locality, Colonia Tovar. It differs widely from that in many morphological characters, nevertheless, 3Bot.

It is actually more closely related to P. Randalli Maxon,® of Jamaica, and P. Hombersleyi Maxon,® of Trinidad, although both of these are diminutive and bear numerous scales upon the rhizome.

Smith’s type material of G. patens, collected in Panama by Seemann, has been examined at Kew and the British Museum, and is well matched by recent Panama specimens, all from the lowlands of the Canal Zone region (Killip 2681a, 2695, 2702; Standley 26174). The name patens not being tenable under Polypodium, this species must be known as P. flagellare Christ, founded on specimens from western Costa Rica, Biolley 2671 (not 2691, as published). Fragments and a photograph of a specimen of the type collection in the Costa Rican National Herbarium are at hand. Dryopteris blanda (Fée) C. Chr. Known previously from Mexico, Guatemala, and Costa Rica, this species may now be reported from British Honduras, on specimens collected in 1907 by Prof. M. E. Peck (no. 707). Dryopteris melanochlaena C. Chr. This remarkable species, hitherto known only from the type specimen collected near Cobdn, Alta Verapaz, Guatemala, by John Donnell Smith (no. 168 in part), may now be reported from eastern Mexico on the basis of an excellent specimen collected at Zacuapam, Veracruz, August, 1929, by C. A. Purpus (no. 13061). The very dark scalelike indusia, beset with rigid whitish cilia, are an excellent diagnostic character. 4Mettenius mentions ‘‘very minute”’ rhizome scales, a character which may be taken from the Fendler or Karsten specimens, these not seen by the writer. b5Amer.

Fronds several, cespitose, recurved-ascending, proliferous, about 65 cm. long, conform; stipes two-thirds as long as the blades, stout (2-2.5 mm. thick), olivaceous, deciduously paleaceous; blades pinnate, 35-40 em. long, linear, about 6 cm. broad at middle, scarcely narrowed at base, about 2 cm. broad at the truncate proliferous apex, the terminal bud large and conspicuously paleaceous, viviparous; pinnae about 30 pairs, alternate, approximate, horizontal, mostly sessile (basal ones petiolulate), trapeziform-oblong, rounded-subauriculate, mucronate at the abruptly acutish tip, mostly 2-3 em. long, 1-1.4 cm. broad, biserrate, the major serrations 2-3 mm. broad, 1-2 mm. long, submucronate, with a short erect tooth in the sinuses; leaf tissue coriaceous, dull green, semiopaque, the margins cartilaginous; veins arcuate, mostly 2—4-forked, impressed above, elevated beneath, here bearing a few very minute, laxly substellate scales; sori slightly supramedial, uniserial, 6-8 on the proximal side, 10-15 on the distal, abraded in the specimens at hand. Type in herb. Univ. Bot. Mus. Copenhagen, collected in mossy forest of Loma La Vieja, Constanza, Prov. de la Vega, Dominican Republic, alt. 2,000 meters, Nov. 7, 1929, by E. L. Ekman (no. H. 14058). A frond from this specimen is in the U. 8. National Herbarium (no. 1,555,593). Most closely related to P. Underwoodii Maxon, of Jamaica, which grows at about the same altitude and has the fronds similarly non-cirrhate and invariably proliferous. That species differs consistently, however, in its subentire pinnae and in leaf-shape, the blades being narrowly elongate- triangular, the attenuate apical portion consisting of numerous, gradually reduced, oblique pinnae, which are decurrent, the uppermost broad! confluent. Polystichum Ekmani is represented also by Ekman H. 12791, from the Moncién region, Prov. Monte Cristi, Dominican Republic, alt. 1,900 meters. One frond of this collection bears at its tip a plant 3 cm. high.

Among the mammals collected during the summer and autumn of 1932 by Miss Annie M. Alexander and Miss Louise Kellogg in the southwestern United States, and given to the Museum of Vertebrate Zoology of the University of California, are specimens representing two undescribed races of Perognathus amplus. One series obtained on the black sand in the vicinity of the Wupatki Ruins of the Wupatki National Monument in northern Arizona represents a race having the highest degree of dark pigmentation yet known in the subgenus Perognathus. Another series from near the Little Colorado River at Cameron, Arizona, is distinct from the Wupatki series and also from other described races of Perognathus amplus. Perognathus amplus cineris, new subspecies. Type.—Male, adult, skin and skull, no. 55771, Mus. Vert. Zool.; from near the Wupatki Ruins, Wupatki National Monument (about 27 miles northeast of Flagstaff), Coconino County, Arizona; collected October 12, 1932, by Annie M. Alexander; original number 1932. Distribution—Known only from ground covered with black sand (volcanic cinders) in the vicinity of the Wupatki Ruins, but possibly also occurring in similar places elsewhere in the San Francisco Mountain volcanic field. Diagnostic characters and comparisons.—A race of Perognathus amplus characterized by small size, nearly black dorsal coloration, and dark ventral coloration. Compared with P. a. amplus Osgood and P. a. pergracilis Goldman: distinctly smaller (see measurements); dorsal coloration prevail- ingly blackish rather than yellowish, subterminal bands much narrower and less richly colored, belly hairs heavily pigmented rather than lightly pigmented or unpigmented, ears much more heavily pigmented, tail less 22—Proc. Bion. Soc. WasH., VOL. 46, 1933. (109) 110 Proceedings of the Biological Society of Washington. distinctly bicolor; skull smaller, more highly arched, mastoid and tympanic bullae less inflated, mastoid bullae projecting less posteriorly to plane of occiput. Much darker and smaller than P. a. rotundus Goldman. Darker than P. a. taylori Goldman. Most like P. a. ammodytes (description below) except in color. Color (terms after Ridgway, Color Standards and Color Nomenclature, 1912).—Dorsal hairs with apical portions black, subterminal bands pale ochraceous-salmon, basal portions plumbeous. Breast and throat white. — Hairs of belly plumbeous basally, tipped with light ochraceous-buff. Tail indistinctly bicolor. Hairs on dorsal side of tail black; on ventral side, black, or pale ochraceous-buff tipped with black, the black hairs most numerous terminally. Hairs of hind feet mixed white or pale ochraceous- buff, the latter predominating. Skin of ears black-pigmented. A stripe of black hairs extends from tip of nose to base of vibrissae. Most note- worthy characters of color are: abundance of black pigment and small amount of yellow pigment in dorsal hairs; narrow subterminal bands; heavy pigmentation of belly hairs and of skin of ears; black stripe from nose to base of vibrissae; nearly unicolor dark tail. Specimens examined.—Total number, 14, all from the vicinity of the Wupatki Ruins. Remarks.—This dark race was found to be closely restricted to ground covered with black sand. The specimens were secured at several places between 2.6 miles west of the ruins and along the road between the ruins and Heiser Spring. Perognathus amplus ammodytes, new subspecies. Type.—Male, adult, skin and skull, no. 55774, Mus. Vert. Zool.; from 2 miles south of Cameron, Coconino County, Arizona; collected August 8, 1932, by Louise Kellogg; original number 1620. Distribution.—Known only from near the type locality. Diagnostic characters and comparisons.—A race of Perognathus amplus characterized by small size, dark dorsal color, and pigmented belly hairs. Compared with P. a. cinerts: general coloration prevailingly yellowish rather than blackish, subterminal bands of hairs of dorsal surface broader, belly hairs tipped with white and less heavily pigmented, tail more dis- tinctly bicolor, all hairs on hind feet white rather than some yellowish and some white, lacks dark stripe between tip of nose and base of vibrissae; size slightly greater; skull averages slightly larger, relatively narrower. Compared with P. a. amplus and P. a. pergracilis: general coloration darker, belly hairs always pigmented, never white; smaller in body size and in skull; mastoid bullae less inflated posteriorly, not projecting as far past plane of occiput. Z Color.—Dorsal hairs with tips black, wide subterminal bands light . ochraceous-buff, basal portions plumbeous. Hairs of breast and throat white. Hairs of belly with French gray bases, subterminal bands of pinkish buff, and white tips. Narrow stripe of black hairs on dorsal side of tail, rest of tail hairs pinkish buff. Hairs of hind feet white. Skin of ears dark-pigmented. A spot of black hairs on nose and at base of vibrissae. > bet Benson—Perognathus amplus from Arizona. 111 Specimens examined.—Total number, 7, all from the vicinity of Cameron, Coconino County, Arizona, as follows: east bank of Little Colorado River at Tuba City road bridge (opposite Cameron), 3; 2 miles south of Cameron, 3; 3 miles south of Cameron, 1. Remarks.—Pocket mice of the amplus group apparently are usually not numerous near Cameron. Three specimens were obtained by F. B. Sumner _and H. 8. Swarth in 1922 on the east bank of the Little Colorado opposite ‘’ Cameron. In 1931 I spent 3 days (630 trap nights) at the same place in an attempt to secure additional specimens, but was not successful. In 1932 Miss Alexander and Miss Kellogg obtained 4 specimens south of Cameron on the west side of the river in sandy ground where the chief vegetation was bunch grass and saltbush. Two other species of Perognathus have their darkest races on the lava and cinder beds of the San Francisco Mountain volcanic field. These are P. flavus fuliginosus Merriam and P. apache cleomophila Goldman. The parallelism in color in these species is probably the result of the same cause, which I believe to be natural selection for concealing coloration. Perognathus amplus is a species clearly distinct from P. flavus and P. apache. The two races of amplus here described are easily distinguishable in the field from the dark races of flavus and apache by having actually and relatively longer, more penicillate tails. They show some approach in small size and long tails to the species P. longimembris which is represented north of the Grand Canyon by the race P. |. arizonensis Goldman, but the differences in size and in skull characters are too great to indicate con- specificity. 112 Proceedings of the Biological Society of Washington. qypBerq [B}IqIoO19zUL YSBOT BUILIBIOS PloJseur -O[A}s WHOA YOq BDUBzSICT S}UIUIOINSBITA [INAS * pro} -SBUI JO Y}Zug] 48078015 syesourenbs jo mds 9a0qe sproy -SBUL SSO1DB YYpBaIg [eseu-oju0L [esbu-0}1d19900 L Fl 08 GC Il 69 G &I € SL 81 ST syrvib.iad Str bL I T snjdwu OL 99 ZL 69 “6 8° 9 LZ sajfipowwun IZ 61 6° 61 L TZ 0Z 8° 06 v syusteInsveyy, Apog Apoq puv pvoyy joo} pulyy 4 io} laa fo a — ® i=} 09 = o ‘(YNOZIUY ‘AUTIVA TVLIULAG WOU) s2pronsbiad snjdwo snywubosag ‘(adkLOAOL) snydwy snjdwv snywoubosag ‘squauto snjdup snyouboiag ‘sajfipowmumpn snjidup snyyoubolag AO SHIVIN WINGY JO SWVUY) UNV SUALAWITIIP, NI SINGWAYASVAYY Vol. 46, pp. 113-118 June 30, 1933 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON THE RACES OF THE TINAMOU CRRQQURELLUS 7h CINNAMOMEUS. NAL MU BY H. B. CONOVER. Having always been greatly interested in the tinamous, recently on receipt of a series of Crypturellus cinnamomeus from Honduras, I undertook a study of all the races of this species. It was surprising to discover that there was little material in this country from north of Honduras and Salvador; therefore, not much could be done with the races found in Mexico, except for C. c. goldmani from Yucatan. From south of Guatemala, specimens were much more numerous and the races could be worked out more satisfactorily. Two forms from northern South America, Crypturus idoneus (Todd) and Crypturellus connamomeus spencer (Brabourne and Chubb) have been called races of cinnamomeus. While they may eventually be proven to be such, the evidence is not yet conclusive; and since the gap in distribution is considerable, I have omitted them for the present. For the loan of material I am indebted to Mr. James L. Peters of the Museum of Comparative Zoology; to Mr. J. T. Zimmer of the American Museum of Natural History; to Dr. Herbert Friedmann of the U. 8. Na- tional Museum; to Mr. A. J. Van Rossem of the California Institute of . Technology, and to Mr. Rudyerd Boulton of Field Museum. Crypturellus cinnamomeus cinnamomeus (Lesson). Tinamus (Nothura) cinnamomeus Lesson, Rev. Zool. 1842, p. 210 (La Union, Central America = Salvador). Specimens examined.—Salvador: 70° 392 from Lake Olomega, Mt. Cocaguatique, Volean San Miguel, Rio San Miguel, Dept. San Miguel; Olomega, Volcan Conchagua, Dept. La Union; and Colima, Dept. Cuscat- lan. Mexico: 1 9? Santa Efigenia, Tehuantepec. 23—Proc. Biou. Soc. WaAsH., Vou. 46, 1933. (113) 114 Proceedings of the Biological Society of Washington. This seems to be the smallest of the races, the wings of Salvador males averaging 156.5 and females 160.5 mm. The single female from Tehuan- tepec, however, has a wing of 174 mm. In coloration this form is very reddish on the breast and dark brownish on the back. Peters (Birds of the World, Vol. 1) gives the range of this race as ‘‘south- ern Vera Cruz and Oaxaca south on Pacific slope to Nicaragua.” He evidently considers C. c. sallaei from Cordoba, Vera Cruz, and C., c. dellat- trii from Nicaragua as synonyms. I am inclined to doubt this and would state the range of the typical race as the Pacific lowlands from the Gulf of Fonseca to the Isthmus of Tehuantepec. Crypturellus cinnamomeus mexicanus (Salvadori). Crypturus mexicanus Salvadori, Cat. Birds Brit. Mus. 27, 1895, p. 516, (in key) p. 545 (Monte Verde, Tamaulipas, Mexico). No specimens of this race seem to be available in the United States, so no comparison could be made. Salvadori in comparing it to C. cinnamomeus says it is less rufous on the occiput and nape, and the female is not barred with black on the lower foreneck and sides of the breast. The range is given as northeastern Mexico. Crypturellus cinnamomeus occidentalis (Salvadori). Crypturus occidentalis Salvadori, Cat. Birds Brit. Mus. 27, 1895, p. 516, (in key) p. 546 (San Blas, Nayarit, Mexico). No specimens have been available. According to Salvadori, in the males the occiput and sides of the head are not rufescent but olive brown, and the lower foreneck and breast are grayish, with no reddish tinge. The only range given is Tepic. Crypturellus cinnamomeus sallaet (Bonaparte). Nothocercus sallaet Bonaparte, Compt. Rend., 42, p. 881, n. 333, p. 954, n. 9. (1856) (Cordoba, Vera Cruz, Mexico). One specimen has been examined from near the type locality. This is a bird taken at Omealea (or Omgalea) near Cordova. It is an old speci- men which seems to have been mounted at some time. The label calls it a female, but as the forehead and the fore part of the crown are unbarred black, I take it really to be a male. The wing measures 169 mm. In coloration it is much lighter (browner, less blackish) on the upper parts than either males or females from Salvador. Basing an opinion on one specimen of course is hazardous, but considering the difference in climate between the north and south sides of the Isthmus of Tehuantepec, it seems that when more material is available, the name sallaei may be reinstated. Crypturellus cinnamomeus inornatus (Nelson). Crypturus inornatus Nelson, Auk, 17, 1900, p. 253 (Metlaltoyuca, Puebla, Mexico). Conover—Races of Tinamou Crypturellus cinnamomeus. 115 Specimens examined.—Mexico: 12 Metlaltoyuca, Puebla; 16, 29 Orizaba, 16’, 19 Jalapa, 1c’ Buena Vista, 1 Pasa Nueva, 1 Mirador (near Vera Cruz), Vera Cruz. There is great doubt in my mind as to what race or races the specimens listed above represent. Certainly the female from Metlaltoyuca is a very much browner bird on the upper parts than all the rest. It may be that the others really represent sallaez, or even mexicanus, or both. The individual variation is so great, however, that it seems impossible to classify them without fresh material from near the type localities. It may be that imornatus will prove to be simply a synonym of sallaez. Crypturellus cinnamomeus goldmani (Nelson). Crypturus sallaet goldmani Nelson, Proc. Biol. Soc. Wash., 14, 1901, p. 169 (Chichen Itza, Yucatan). Specimens examined.—Mexico: 22 Chichen Itza, 2c’ Temax, 32, 3c Yucatan. Guatemala: 2 2 Uaxactun, Peten. The females of goldmani are distinguished from all other races by the sharp contrast between the dark reddish chest and upper breast and the very light buffy white lower breast and belly. Compared to typical cinnamomeus the upper parts and the chest in both sexes are lighter, less reddish. Wings of females from Yucatan average 161.8; males 164.4 mm. Range.—Throughout the Yucatan Peninsula and northern Guatemala. Crypturellus cinnamomeus vicinior, subsp. nov. Type from La Flor, near Archaga (about half way between Tegucigalpa and Comayagua), Dept. Tegucigalpa, Honduras. No. 10368, adult male in the Conover Collection, Field Museum of Natural History, Chicago. Collected June 14, 1932, by C. F. Underwood. Characters.—Differs from C. c. cinnamomeus on the upper parts by being lighter, more brownish, less reddish. This is especially noticeable on the nape, back of the neck, and mantle. The light barring on the tail, rump, and upper wing coverts is whiter and broader. On the under side the chest, upper breast, and sides are lighter, more ochraceous, much less reddish, while the lower foreneck is lighter gray. It is also considerably larger, females averaging 171.2, males 167 mm. Differs from C. c. dellattrii on the under side by being lighter, more ochraceous, less reddish (dellatiriz in the reddish color of its breast is about midway between vicinior and cinnamomeus). On the upper side the females are much lighter brownish, less reddish, but in the males this difference is less pronounced. In both sexes, however, the barring of the upper wing coverts is heavier and whiter, therefore much more pronounced. Differs from C. c. praepes by having the upper parts lighter, more grayish, less brownish, and by having the barring of the upper wing coverts whiter and more pronounced. On the under side it is slightly lighter on the chest, and the gray of the foreneck and upper chest is lighter and much less exten- ‘sive. The female of vicinior differs radically from the female of praepes 116 Proceedings of the Biological Society of Washington. in having only a slight, inconspicuous barring on the foreneck and chest. In praepes there is heavy barring in all eight examples before me. Differs from C. c. goldmani by being lighter, less reddish on the chest and upper breast, and in the females by being darker, more ochraceous on the lower breast and belly. On the upper parts the females are much less reddish on the nape and back of the neck, while the males are slightly lighter on the back. It is also somewhat larger than goldmani. Description.—Yorehead and crown black. Nape and back of the neck rufescent, indistinctly barred with black. Mantle, upper back and secapu- lars grayish brown with an olive tinge and very finely vermiculated with blackish. Lower back and upper tail coverts grayish brown barred with black, the bars becoming wider on the tail coverts. Tail black, barred with buff, and tipped with buffy white. Primaries and secondaries dark brown, the latter barred on the outer web with buffy white, these bars becoming obsolete on the outermost ones. Primary and secondary coverts dark brown, barred widely with buffy white. Outer wing coverts dark brown, inner ones grayish with light buff tips. Sides of the head and neck ochra- ceous, the latter with a rufous tinge. Throat white, foreneck light gray, chest and breast ochraceous buff, with a grayish tinge on the upper chest. Abdomen buff. Flanks dark brown barred with buff. Under tail coverts dark brown at base, the terminal third ochraceous buff, sparsely splotched with dark brown, and almost white at the tip. Wing 170, tarsus 46, culmen 25, middle toe (with claw) 33 mm. Specimens examined.—Honduras: 176’, 32 Hatillo, 66°, 22 La Flor, 1 Monte Redondo, 1 Cerro Cantoral, Dept. Tegucigalpa. Mexico: 16’, 19 Canjob, Chiapas. The females of this new race differ markedly from the females of the neighboring races, cinnamomeus, goldmani, dellattrii, and praepes. The males, although differing markedly from males of cinnamomeus, closely approach specimens of the same sex in the other three, especially goldmant. The two specimens from Chiapas agree perfectly with the series from Honduras. Range.—Western highlands of Honduras, and probably those of Guate- mala and Chiapas. Crypturellus cinnamomeus dellattrii, Bonaparte. Tinamus dellattrii Bonaparte, Compt. Rend., 38, p. 663, 1854 (Nicaragua). Specimens examined.—Nicaragua: 107, 5 2 from Volean de Chinandega, San Geronimo, Volcan Viego, Tepitapa, Leon, and Muy Muy. The females of this race are only slightly lighter on the underparts than those of typical cinnamomeus, and on the upper parts there is no difference. In cinnamomeus, however, the females are distinctly barred on the lower neck and upper chest, while in dellattrit barring is absent or very indistinct. In the males, the Nicaraguan birds are much lighter, more brownish on the upper parts and less reddish on the chest and upper breast. In size this form is much larger, equalling praepes in this respect. The average of the wings of females is 168.8 and of males 165.9 mm. Range.—Probably confined to northwestern Nicaragua.

Zool., 67, No. 15, 1927, p. 472 (Bolson, Costa Rica). Specimens examined.—Costa Rica: 40’, 89 from Las Canas, Bebedero, Huma, Paquera and Ballina. This seems to be the largest of the races. The eight females have wings averaging 167.5 mm. and the four males average 171.75 mm. In coloration the females are paler and browner on the upper parts than typical cin- namomeus, and on the under side are much less reddish on the chest and lighter, more buffy on the lower breast and belly. They are also much more heavily barred on the lower neck and chest than in any other race. The males are lighter brown, less reddish on the upper parts, and on the under sides are paler, more buffy.

BY HERBERT FRIEDMANN! AND W. WEDGWOOD BOWEN. In 1900 (Journ. f. Ornith., p. 263) Neumann described a western race of this bird as Corvinella corvina togoensis, using as his comparative material birds from Senegambia and Kavi- rondo. The latter he assumed to be true C. c. affinis Hartlaub, the type locality of which is Nubia. Neumann apparently had no topotypical affines, which is not surprising as the species is not known from Nubia proper. Heuglin (Sitzungs. Kais. Akad. Wissensch. Wien., 19, 1856, 286), whose first use of the name affinis was validated by Hartlaub the next year, merely says that the bird is abundant on the Bahr el Abiad (White Nile) south of 7° N. Latitude. Before discussing the variations of this shrike in the eastern part of its range, mention may be made of the name C. c. nubiae Filippi. This name, referred to by several authors, we have been unable to trace, all references found being erroneous. If found, it may have to replace affinis. Recent study of material from Kavirondo, Uganda, northeastern Uelle district, Belgian Congo, and the Sudan (Bahr el Ghazal, Mongalla, and southern Darfur provinces) shows that the Kavirondo birds are not affinis, but belong to a distinct, unnamed race. Furthermore, the birds of the southern Bahr el Ghazal are again distinct. These may be described as follows: Corvinella corvina chapini, subsp. nov. Type.—Acad. Nat. Sci. Phila., no. 97846, adult female, collected at Kibigori, Kavirondo, August 21, 1918, by A. Blayney Percival. Subspecific characters.—Similar to C. c. affinis from Bahr el Jebel and southern Darfur, but slightly darker and more heavily streaked above and below, and with the rufescent area in the primaries more restricted basally (distance from distal end of rufescent area to tip of fourth primary averaging 50.8 mm. in a series of chapinz from Kavirondo as against 43 mm., in a series of C. c. affinis). 1Published by permission of the Secretary of the Smithsonian Institution. 25—Proc. Biot. Soc. WasH., Vou. 46, 1933. (121) G54 ah 122 Proceedings of the Biological Society of Washington. Distribution. Kavirondo and Elgon district through Uganda (Rhino Camp) to the northeastern Belgian Congo (Vankerckhovenville and Garamba). We take pleasure in naming this race in honor of Dr. James P. Chapin of the American Museum of Natural History. Corvinella corvina caliginosa, subsp. nov. Type.—Acad. Nat. Sci. Phila., no. 104553, adult male, collected at Rangu, southern Bahr el Ghazal, April 16, 1931, by Dr. H. Woodman. Subspecific characters.—The grayest of all the races and the most heavily streaked above and below; in the character of the rufescent wing area intermediate between affinis and chapini (the distance from distal end of rufescent area to tip of fourth primary averaging 47.5 mm.); tail very long (188.5-191 mm., as against 174-175 mm. in affinis and 175-177 mm. in chapini (one specimen from Garamba approaching caliginosa, with a tail of 187.5 mm.). Distribution.—Known only from the Yambio district, southern Bahr el Ghazal. The races of this species, then, are as follows: 1. Corvinella c. corvina Shaw. Senegal and Gambia east to Hausaland, northern N. Nigeria. Material examined.—Senegal, 2 (U. S. Nat. Mus.); 1 (Amer. Mus. Nat. Hist.); Gambia, 1 (Acad. Nat. Sci. Phila.); ““W. Africa,” 1 (Acad. Nat. Sci. Phila.). 2. Corvinella c. togoensis Neumann. Portuguese Guinea to the Banso Mts., Cameroon, and to N. Nigeria. Sclater (Syst. Av. Aethiop., pt. 2, 1930, p. 615) considers this form to be doubtfully distinct from typical corvina. The single specimen seen by us is insufficient to enable us to express an opinion. Material examined.—Kati, French Sudan, 1 (Amer. Mus. Nat. Hist.). 3. Corvinella c. affinis Hartlaub. Upper Nile district through northern Bahr el Ghazal to central Kordofan and Darfur.

June 30, 1933 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF oo, REMARKS ON THE GENUS LIMNODROMUS. WIED. BY PIERCE BRODKORB. Some eighty years ago Bell: and Lawrence’ separated the dowitcher of western North America from the eastern bird, now known as Limnodromus griseus griseus (Gmelin). Up to the present time Limosa scolopacea Say has been thought to be the earliest name for this western bird. Comparison of Say’s description with specimens, however, shows that his name is a synonym of Gmelin’s griseus. I quote the distinctive passages, omitting those which might apply to either form: “. . . cheeks, chin, throat, and origin of the breast cinereous; . . . tail coverts and tail white fasciate with black, .. . breast and belly white; sides spotted and undulated with blackish cinereous; inferior tail coverts with black abbreviated bands, the white prevailing . . .” In this description no mention is made of the prominent bars on the throat and upper breast of the Alaskan bird, while griseus often has these parts almost immaculate. The tail and its coverts are said to be black and white as in griseus, instead of the black and deep cinnamomeous of the Alaskan bird. The sides are spoken of as spotted and undulated, which is exactly the case in griseus, but not so in the Alaskan bird. Griseus, too, often has the lower breast and belly white in spring, while the Alaskan bird seldom does. Say gives the bill length as 234 inches, a measurement about one milli- meter longer than any I have obtained for griseus. This small discrepancy may be accounted for by a different method of measuring the bill, or perhaps the measurement was inaccurately taken. It is evident that Say was unacquainted with Scolopax grisea Gmelin, for he was so struck by the characters of his bird that he proposed to erect a new genus for it. When these facts are considered, together with the apparent scarcity of the Alaskan form in Iowa, whence came Say’s type, it seems clear that the 1Bell, Ann. Lyc. Nat. Hist. N. Y., V, 1852, 1. 2Lawrence, ibid., 4. 3Say, in Long’s Exped. Rocky Mts., I, 1823, 170. 26—Proc. Brox. Soc. WasH., Vou. 46, 1933. (123) ad 124 Proceedings of the Biological Society of Washington. bird Say described was a spring example of Limnodromus griseus griseus of the extreme type in which the breast is almost without markings. Scolopax longirostis Bell is merely a new name for Limosa scolopacea Say and must therefore also apply to Limnodromus griseus griseus. The form of dowitcher breeding in Alaska is thus left without a valid name. It may be known as Limnodromus griseus fasciatus, subsp. nov. Type.—Female adult, ‘‘shot by nest,’’ no. 3693, collection of H. B. Con- over; Hooper Bay, Bering Sea, Alaska; June 9, 1924; H. B. Conover, original no. 879. Wing (flat), 149 mm.; tail, 57 mm.; culmen, 74.5 mm.; tarsus, 40 mm.; middle toe with claw, 31.2 mm. Characters.—Similar to Limnodromus griseus griseus, but wing averaging slightly shorter; culmen, tarsus, and middle toe averaging longer. Summer adults with throat and usually chin flecked with dusky, the marks becoming extended posteriorly to form well-defined transverse bars on upper breast; sides of breast and usually under tail-coverts barred with black; general color of lower parts, including under tail-coverts, vinaceous cinnamon,‘ the white tips of the feathers larger in the same stage of wear; light bars of central rectrices and upper tail-coverts oftener cinnamomeous, usually orange-cinnamon; cinnamomeous markings of tertials, scapulars, and interscapulars deeper, often orange-cinnamon. Winter adults with throat and breast brokenly barred with darker; under tail-coverts and sides of breast usually barred. Juvenals with ochraceous below usually duller; cinnamomeous markings of upper parts deeper, between vinaceous-tawny and orange-cinnamon; under tail-coverts often barred.

Prof. William Rowan has lately treated this bird as a distinct species.® Contrary to his statement, however, intermediates between fasciatus and griseus are by no means rare. Over twenty individuals of the series exam- ined in the present connection are not typical of either race. Some few, in fact, are so intermediate that it is very difficult to say to which form they are closer. Not having seen breeding birds from Yukon and Mackenzie, I am unable to state just where the area of intergradation is. Six spring intermediates from Kuiu Island, southeastern Alaska, however, give weight to the supposition that the Mackenzie Valley is the meeting-ground of the two races.

Brodkorb—Remarks on the Genus Limnodromus Wied. 127 I can find nothing to substantiate the recently described Limnodromus griseus hendersoni Rowan. There is every possible variation between the characters attributed to this bird and ‘“‘typical”’ griseus. Breeding birds from Alberta differ so much among themselves that it is impossible to distinguish them, either by color or by size, from Atlantic coast birds. The white belly appears to be a character of one-year old birds or those not in full plumage and would seem to be of no geographical significance. It is, moreover, in the light of all past evidence, very unlikely that any form of dowitcher breeds regularly east of Hudson Bay, a condition which leaves true griseus (so-called) without a breeding range. Limnodromus griseus hendersoni Rowan thus becomes a synonym of Limnodromus griseus griseus (Gmelin). From the specimens listed above it will be seen that this race is quite common on migration along the California coast. Limnodromus semipalmatus (Blyth). M{acrorhamphus| semipalmatus ‘“‘Jerdon,”’ MS., Blyth, Journ. Asiat. Soc. Bengal, new ser., XVII, pt. i, no. 15, March, 1848, 252 (“‘Calcutta bazar’’). Micropalama tacksanowskia Verreaux, Rev. et Mag. de Zool., 2nd ser., XII, May, 1860, 206, pl. 14 (‘‘la Daourie’’). Remarks.—Of this species five specimens have been examined from the following localities: China: Chibli (Peitaiho), 2. Siam: Bang Hia, 3. If semipalmatus is excluded from Limnodromus and placed in Pseudo- scolopax Blyth, as has recently been done,® we have two monotypic genera instead of one genus containing two species. The only structural character by which the two “‘genera”’ may be separated is the web between the inner and middle toes of semipalmatus, which is absent in griseus. In juvenal and winter plumages the two birds are very similar. For these reasons it seems best to consider the web of semipalmatus as a good specific character, rather than of generic value.

Thayer, and to the authorities of Coe College, Field Museum of Natural History, the Museum of Comparative Zoology, the Museum of Vertebrate Zoology, the University of Illinois, and the University of lowa.

Among the spoils of a collecting trip made in the summer of 1932 by Hobart Smith and myself in Mexico are two forms of the genus Huwmeces which appear to be unnamed. ‘These are from the southern part of Mexico; one, the smaller, from the central part of the State of Guerrero; the other, a larger form, from the State of Mexico. The smaller form seems to show relationship with the breviros- tris group, which is largely Mexican in distribution. The second form has been known since 1885 when Cope! published a short description of the form under the name of “‘ Humeces brevirostris Gthr. Var.” Despite the fact that Cope associated the species with £. brevirostris, | am of the opinion that the relation is not with this group. I suspect that its nearest relationship is with Eumeces anthracinus or Eumeces septentrionalis, although not closely related with either. Eumeces ochoteranae, sp. nov. Type.—No. 1015.

The scales preceding the ear between ear and seventh labial are usually as described, but may be replaced by two elongate ones, or three, the two upper uniting. The character of the temporals (the relation of the seventh labial to the upper secondary temporal) is variable, and they are separated in about half of the specimens and form a common suture in the other half. The number of subcaudal scales varies from 84 to 90. Relationship.—This form is apparently related to Humeces brevirostris, but differs in having a lower average count of scale rows; smaller and shorter limbs; the much broader dorsolateral line (separated by two whole and two half dark colored scales); the absence of a lateral light line along the sides of abdomen; the retention of blue color in the tails of adults and a smaller average of scales from parietals to anus (usually 6 to 8 less). Habitat.—This form was first encountered at Mazatlan, near Chil- panzingo, Guerrero, Mexico, June 26, 1932. The specimens were routed from under stone and leaves and the rotting masses of agave plants. A few days later, July 1, 1932, several specimens were taken high in the Taylor—Mexican Skinks of the Genus Eumeces. 133 mountains in pine forest between the villages of Rincon and Cajones, south of Chilpanzingo. These specimens were found usually in rock ledges and under leaves at the base of large boulders. A total of eleven specimens were taken. No other species of the genus was found in our collecting in the State of Guerrero. The species is named for Dr. Isaac Ochoterena, Director of the Instituto de Biologia, Chapultepec, Mexico, D. F. Mexico, a noted Mexican histolo- gist and botanist, as an expression of appreciation for innumerable courte- sies extended to Mr. Smith and myself while sojourning in Mexico. Kumeces copei, sp. nov.

A cream white lateral line begins on rostral, passes along the lower part of the first four labials, then rises somewhat, passing across the upper part of the succeeding labials, reaching middle and upper edge of ear; behind ear it begins on lower half of the ear edge, then bends down slightly, continuing back above arm along the side and to some distance on the tail. A deep black or black-brown stripe begins on the side of the head, runs along the side, occupying the area between the light lines and bordering the inner edge of the lateral; on the median part of the back there are five brown lines; the three median, which follow the edges of the scale rows, are quite distinct, but are much lighter in color and narrower than the deep black-brown lines bordering the light dorso- lateral lines; head with a few black-brown spots; below the lateral light line, sides black-brown, each scale with a lighter grayish area forming more or less distinct lighter lines; lower labials, chin, abdomen, underside of limbs, and tail dirty grayish to bluish gray, the preanals showing some browaish color; scales of arm and leg showing irregular light dots, the fingers with cream dots on each scale, the toes only partly so; soles and palms bluish black.

There is some variation in the shades of brown forming the ground color and in a few specimens the three chocolate lines bordering the edges of the three median scale rows are dim or rarely missing; occasionally, the dark spots on the dorsal part of the head are wanting. The scale characters show some variation. The frontal occasionally is separated from the frontonasal (8 times in 86). The parietals fail invariably to enclose the interparietal; the sixth and seventh upper labials are of about equal area, the seventh occasionally the largest; there are invariably four supraoculars, three of which touch the frontal (one exception); seven upper labials (one exception with six); the scales about the ear vary be- 2IT have just examined another specimen of this species which Dr. G. K. Noble has forwarded from the American Museum of Natural History (No. 19293 Santa Lucia, Dis- trito Federal, Mexico). It is a young specimen lacking the three median brown lines. 136 Proceedings of the Biological Society of Washington. tween 15 and 17; invariably one postmental and no postnasal; supercili- aries vary between six and seven (five in two specimens). Usually one auricular lobule (rarely two, or none, enlarged). The frontonasal invari- ably touches the first loreal. The lamellae under the fourth toe vary between 12 and 14, 13 being the most frequent number (two specimens have 16 on one side); postsuboculars usually three (three exceptions with four). In the greater part of the specimens the primary temporal is larger than the lower secondary (which is unusual in the genus) and is invariably in contact with it, thereby separating the seventh labial from the upper secondary temporal. The limbs when adpressed fail to touch save in the smallest specimens (29-34 mm.) where they may overlap one or two millimeters. Habitat.—The specimens were found for the most part under rocks or logs. A single specimen was obtained by Hobart Smith in the lava field along the highway between Mexico City and Cuernavaca about 60 kilo- meters from the type locality. The others of the type series were found in the western part of the State of Mexico, Mexico, between Toluca and Asuncion at elevations between 6000 and 9000 feet. There are two specimens belonging to this species in the United States National Museum, but both are from indefinite localities. One is a dis- colored specimen with the color pattern practically obliterated (no. 7037 from ‘‘Mexico’’); the other is the specimen mentioned by Cope loc. cit. This specimen shows the color pattern. It is from “Hither the valley of Mexico, or the adjacent one of Toluca.’ In the Museo Nacional de Mexico there is a specimen presumably from the mountains between Mexico City and Toluca which is labelled Hwmeces ‘“‘herrerae.” A search through available Mexican publications, and in- quiries made, fail to show that this name was published. Remarks.—The type series numbers 32 specimens of various age and sex. An examination of the sex organs fail to disclose whether the form is ovoviviparous or not. All the females lack developing eggs, save the United States National Museum specimen, which shows five developing eggs in the ovaries. The stomachs contain a variety of insects belonging to several families, chiefly coleoptera and blattids. No ants were observed. The species is named for Edward Dinker Cope, who first noted the form, but failed to give it a name. Taylor—Mexican Skinks of the Genus Humeces. 137 sp. nov.

Herewith are presented notes on several tropical American ferns. They are additional to two earlier papers under the same general title.’ SCHIZAEACEAE. Actinostachys penicellata (H. B. K.) Maxon. Schizaea penicellata Humb. & Bonpl.; Willd. Sp. Pl. 5: 86. 1810. Schizaea subtrijuga Mart. Icon. Crypt. Bras. 117. 1834. This name having been used in identifying recent Trinidad material, the formal transfer may appropriately be made. CYATHEACEAE. Alsophila phalaenolepis C. Chr. Founded on an Ecuador plant in the Bonaparte Herbarium, collected by Sodiro in 1904. Agreeing closely is a complete isotypic specimen in the National Herbarium. The range of this species is considerably extended by material collected in the Dagua Valley, Dept. El Valle, Colombia, in 1922, as follows: Cérdoba, alt. 80-100 meters, Kill¢zp 5103; Santa Rosa, alt. 200-300 meters, Killip 11528, 11566. No. 5103 shows a slender erect rhizome more than 20 cm. long, as opposed to the very short rhizome in the type specimen. GLEICHENIACEHAE. Dicranopteris nuda (Moritz) Maxon. With recent exploration this species appears much commoner than previously noted.? The following specimens are now at hand: VENEZUELA: Colonia Tovar, Moritz 452 (type); H. Piitier 9344. Moun- tains near Galipdn, H. Pittier 128. Between El Carrizel and San Diego, alt. 1,400 m., H. Pittier 129838. Tabay, alt. 2,200-2,300 m., Gehriger 407. Mountain above Caracas, Woronow 7215.

In transferring this South American species to Dicranopteris in 1922, the writer overlooked the fact that D. Williamszi, founded on a Panama plant (Williams 917), should be included. The following additional specimens of D. remota, considerably extending the range, have been received in the interim: Trinipap: Las Lapas Road, alt. 600 meters, Hombersley 280, 327a, 327b, 327c.

Fil. 383. 1862. Founded on specimens from the region of Caracas, Moritz 91. Agreeing closely with a fragment of the original collection at the New York Botanical garden is the following specimen in the National Herbarium: Paramo del Molino, near Mérida, Venezuela, alt. 2,500 meters, Feb. 19, 1922, A. Jahn 943. Dicranopteris Brittonii Maxon, Contr. U.S. Nat. Herb. 24: 47. pl. 18. 1922. Described from Mount Tocuche, Trinidad, on Britton, Hazen & Mendel- sohn 1352. Recent additional material (Broadway 5657, 7134) from the same locality gives a much clearer idea of the vascular structure. POLY PODIACEAE. Polypodium microchasmum Baker, Journ. Bot. Brit. & For. 25: 44. 1887. The original material consists of only two specimens, (1) the actual type (at Kew), a single small incomplete frond, and (2) a somewhat smaller but better specimen in the Jamaica Herbarium (Hope Gardens), consisting of a sterile and a fertile frond attached to a portion of the rhizome, both speci- mens having been collected at Tweedside, Jamaica, by Mrs. Barrington Baker in October, 1885. The peculiar rhizome scales, scales of the under side of the blade, and remotely notched cartilaginous margins show the plant to be P. plebeium Schlecht. & Cham., a species not known otherwise from Jamaica. The species name given by Baker is most misleading, since the sori are not at all immersed in the blade, being only a little impressed in drying. Paltonium lanceolatum (L.) Presl. A widely distributed characteristic West Indian species, known hereto- fore in continental America only from Honduras (J. D. Smith 5667, Mazxon.—Fern Miscellany—lITT. 141 Standley 54003) and Florida. It has lately been collected in Chiapas, Mexico (Mell 2047). Adiantum Wilsoni Hook. Known in the West Indies previously from Jamaica, Porto Rico, and Hispaniola, this species may now be reported from Cuba: Near Boyate, alt. 450 meters, in a small forest ravine, December, 1923, Hioram 6917. On the continent its range extends from British Honduras and Guatemala to the Isthmus of Darien. In the southernmost part of its range it over- laps A. cordatum Maxon,* of eastern Panama, which it superficially re- sembles, but that species departs widely in its wholly areolate venation. Cheilanthes longipila Baker. A rare Mexican species, founded on Parry & Palmer 989, from the region of San Luis Potosi, alt. 1,800—-2,400 meters, which is lacking in the Gray Herbarium and the National Herbarium. Agreeing with the type specimen (at Kew) are the following more recent collections: Barranca near Guada- lajara, on shaded ledges, H. Palmer 78; Pringle 1863, 11776. These were originally misidentified as C. Cooperae HWaton, a California species. -Cheilanthes albida Baker. Founded on specimens collected in ‘22° N. Lat., alt. 6,000-8,000 ft., chiefly in the region of San Luis Potosi,’ Mexico, by Parry & Palmer (no. 999), and recognized in Christensen’s Index Filicum as a valid species. The type at Kew is, however, annotated by Underwood as C. Lindheimeri Hook., and examination of an excellent isotype, until recently misplaced, in the National Herbarium confirms this opinion. This species is common in the southwestern United States, and extends southward sparingly through Sonora, Chihuahua, and Durango to San Luis Potosi. Pteridium psittacinum (Presl) Maxon. Pteris psittacina Presl, Delic. Prag. 1: 185. 1822. In the Kew Herbarium there is a Brazilian specimen collected by Martius, identified by Baker as Pieris aquilina var. psittacina, which agrees fairly well with Presl’s original description of Pteris psittacina (based on a small sterile plant), apparently representing a valid species. The main points of distinction are the fine dissection of the small blade, which thus resembles certain species of Hypolepis, and the pronounced but variable white- or sordid-setulose covering of hairs on both surfaces and particularly along the margins. Other specimens at hand are as follows: Brazit: Blumenau, Prov. Santa Catharina, Nov., 1887, Ule(?) 290 (identified by Christ as Hypolepis nigrescens); Rio de Janeiro, marsh, July 17, 1927, Harshberger 885. Costa Rica: Near San José, alt. 1,035 meters, Cooper (J. D. Smith, no. 6018); without locality, Werckle (both identified by Christ as Hypolepis nigrescens). 4Amer. Fern Journ. 21: 136. 1931. 142 Proceedings of the Biological Society of Washington. Dominican Repusuic: Laguna de Cenobi, Moncién, Prov. Monte Cristi, alt. 1,100 meters, Hkman H. 12990. Harti: Near Mission, alt. 1,000 meters, Leonard 3916. Of this material only the Harshberger specimen is fertile, showing plainly the ‘“‘double indusium”’ characteristic of the genus. Asplenium rutaceum (Willd.) Mett. This species, founded on illustrations of a Hispaniola plant collected bh: Plumier, has recently been found again in that island by Ekman (no. H. 5447). It should have been included by the writer in the “‘ Pteridophyta of Porto Rico,’’® Urban’s identification® of a specimen (at Berlin) collected long ago by Schwanecke having been found correct. This species is not otherwise known from the West Indies, the Jamaica plant so listed by Jenman being A. conqguisitum Underw. & Maxon. In northern South America it is not especially uncommon. Diplazium verapax (Donn. Sm.) Hieron. Hedwigia 59: 322. 1917. Asplenium verapax Donn. Sm. Bot. Gaz. 13: 77. pl. 2. 1888. Aspleniwm cordovense Baker, Ann. Bot. 8: 125. 1894. Diplazium cordovense C. Chr. Ind. Fil. 230. 1905. Asplenium verapax, founded on a Guatemala plant collected by von Tirckheim (J. D. Smith, no. 850), was reduced subsequently’? by Capt. Smith to A. Riedelianwm Bong., of Brazil, and this view may be correct, in spite of the distinctions stated by Hieronymus’ in recognizing both as valid species under Diplaziwm. The present note, however, is to point out that D. cordovense (Baker) C. Chr., differs in no important detail from D. verapax. The type of A. cordovense, at Kew, is a plant collected near Cordova, Veracruz, Mexico, by H. Finck (no. 143), and is matched by a specimen of the same collection in the U.S. National Herbarium (no. 47), which certainly is indistinguishable from the type specimen (figured) of A. verapax. Two specimens of D. verapax are at hand also from western Panama (Cornman 951, 1266). This species is variable not only in soriation but in relative length of the basal pinnae and in lobation toward the apex. Blechnum nigrosquamatum Gilbert, Bull. Torrey Club 24: 258. 1897. Founded on Bang 2314, from Colopampa, Bolivia, in running water, July 4, 1894, and listed in the Index Filicum as valid. It differs in no respect, however, from Blechnum brasiliense Desv., widely known from Brazil, Paraguay, Argentina, Uruguay, and Peru, and from at least two other Bolivian collections (Buchtien 3359, Williams 1148). Leptochilus Stuebelii (Hieron.) Maxon. Hypoderris Stuebelii Hieron. Hedwigia 46: 223. 1907. Examination of the two type specimens from Ecuador (Stiibel 906), courteously lent from Berlin, shows at once that, although sterile, they are 5Sci. Surv. Porto Rico 6: 373-521. 1926. 6Symb.

They represent a species belonging to the group of Leptochilus nicotianaefolius, the nearest relationship being with L. Bradeorum Rosenst., of Costa Rica. Like L. Bradeorum and L. hemiotis Maxon, of Trinidad, L. Siwebelii is viviparous in the axils of the lateral pinnae. Dryopteris lingulata C. Chr. At the time of its description in 1913 this striking species (subgenus Meniscium) was known only from a single collection, Pittier 10349, from the lowlands of Costa Rica. Additional material in the National Herbarium is as follows: Costa Rica: Hamburg Finca, on Rio Reventzén below Cairo, alt. 55 meters, Standley & Valerio 48659. Panama: Foothills of Garagard, Sambi Basin, southern Darien, alt. 30-500 meters, Prtiver 5596. Cotoms1a: Tutunendo, 20 km. north of Quibd6, Intendencia del Chocé, alt. 80 meters, Archer 2130. The known range thus greatly extended is an entirely natural one. Tectaria Buchtienii (Rosenst.) Maxon. Aspidium Plumieri var. brasiliense Rosenst. Hedwigia 46: 113. 1906.

There is at hand a specimen of the type collection, from Bolivia; Antahua- cana, Espiritu Santo, alt. 750 meters, in shady forest, June, 1909, Buchtien 2171. Ormoloma Maxon, gen. nov. Rhizoma repens, tenue, paleaceum. Folia pauca, subdisticha, 1-pinnata, stipitibus rachibusque atropurpureis; pinnae paucae, nonarticulatae, sublanceolatae, crenatae, subaequales, costa percurrente, venis liberis distantibus 1—3-furcatis, venulis ad basin dentium egredientibus; sori terminales, intramarginales, plerumque solitarii, superficiales, transversi, dentibus herbaceis oppositis multo minores; indusia membranacea, semi- orbicularia vel anguste lunata, marginibus parallela, tantum basi lata affixa; sporangia multa, annulo 10- vel 11l-articulato, sporis triplanatis trilobatis. Rhizome creeping, very slender, laxly and deciduously paleaceous; roots radiculose. Fronds few, distant, subdistichous, suberect, simply pinnate; stipe and rachis atropurpureous, lustrous; pinnae few, nonarticulate, petiolulate, of a lanceolate type, crenate, subequal, the terminal one conform; costa medial and percurrent, the lateral veins few, distant, free, mostly 1-3-forked, the branches excurrent singly to base of marginal crenations; sori terminal, intramarginal, mostly solitary, superficial, much smaller than the opposed herbaceous (unmodified) crenations, transversely elongate; indusia semiorbicular to narrowly lunate, parallel to the margin, affixed at broad base only, membranous; sporangia numerous, the annulus 10- or 11-celled; spores triplanate, trilobate. A single species, the genotype, Saccoloma Imrayanum Hook. The fern under consideration was first described under Saccoloma, from material collected by Imray in Dominica. It was later referred to Davallia 144 += Proceedings of the Biological Society of Washington. by Hooker, doubtfully to Humata by Kunze in 1857, and definitely to Acrophorus by the latter writer in 1861. Kuhn (1882) placed it in another Old World genus, Schizoloma, but Diels removed it to Saccoloma again, at the same time commenting® on the tenuous lines separating the genera of Davallieae and the need of a thorough revision of the tribe. By the writer it has long been regarded as the type of a new genus. This opinion is shared by Copeland, who in recently subdividing Saccoloma pointed out'® the essential characters but courteously refrained from naming the genus. From Saccoloma (properly restricted to S. elegans Kaulf.) and Ithycaulon Copel.,"! which are characterized by massive erect rhizomes, saccate or even cornucopiate indusia, and a 14- to 19-celled annulus, Ormoloma departs widely in its very slender creeping rhizome, its nonsaccate indusia (attached only at the horizontal base), and its 10- or 11-celled annulus. The indusial characters are shown fairly well in the illustrations herewith cited: Ormoloma Imrayanum (Hook.) Maxon. Saccoloma Imrayanum Hook. Gen. Fil. pl. 58, B, f. 5, 6. 1889, nomen; Kunze, Farnkr. 1: 86. 1842. Davallia Imrayana Hook. Sp. Fil. 1: 171. pl. 49, A. 1846. Specimens are at hand from Dominica (Lloyd 881), Guadeloupe (I Her- minier; Duss 4176), Haiti (Ekman 7425), British Guiana (im Thurn 120), and French Guiana (Leprieur 117), the altitudes ranging from 750 to 1,750 meters. Reported from Costa Rica by Baker” on specimens collected by J. J. Cooper; but these, as shown by ample recent material from the mountains of Costa Rica and adjacent parts of Chiriqui, represent a closely allied second species of Ormoloma still to be described. Presumably referable to this new species also is the Costa Rican plant listed by Christ’ as S. Imrayanum. The systematic position of Christ’s Saccoloma Wercklei, described from Costa Rica at the same time, is highly uncertain; but if the description" is really credible, the plant must be related to Saccoloma in soriation characters, rather then to Ormoloma. HY MENOPHYLLACEAE. Hymenophyllum lanatum Fée. This species, previously known from Hispaniola, Jamaica, Cuba, and Guadeloupe, may now be reported from Porto Rico, on the basis of speci- mens collected long ago by Schwanecke, which were identified as H. hir- sutum (L.) Swartz and were so listed by Urban. The material, which is scant and depauperate, has recently been studied on loan from Berlin. 9In Engl. & Prantl. Nat. Pflanzenfam. 14: 205. 1899. 10Univ. Calif.

Cruegeri C. Mill., the Criiger element being presumably isotypic. The plants were found to agree with recent material identified as H. delicatissimum Fée, a later species founded on Glaziow 3591, from Brazil, which apparently must be reduced to synonymy. Besides fragments of both type collections, numerous specimens are at hand from Hispaniola, Guadeloupe, Grenada, Trinidad, and British Guiana. ee ee Vol. 46, pp. 147-150 June 30, 1933 PROCEEDINGS ~ LMA OF THE BIOLOGICAL SOCIETY OF W he ——— DESCRIPTIONS OF NEW SPECIES OF CRABS FROM THE GULF OF CALIFORNIA.

The following new owl was found in a series of skins of this species in the U. 8. National Museum. Ciccaba virgata amplonotata, subsp. nov. Subspecific characters.—Nearest to Ciccaba virgata squamulata Bonaparte, but spots on crown, hindneck, and back much larger, 3 to 8 mm. across instead of 1 to 38 mm., most of them pure white instead of buffy, some of them crescent-shaped, the white continuous across shaft, and there are no minute mottlings of grayish or buffy between the spots; greater, middle, and lesser primary coverts with many large white spots on each web, those on greater coverts often more than 8 mm. across; some of the feathers on the breast with a buffy or whitish spot, 8 mm. or more across, on each web, entirely enclosed by the dusky or dark brownish of the shaft stripe. Type.—Adult, unsexed, U. 8. Nat. Mus. No. 50,764, collected by A. J. Grayson, Mazatlan, Sinaloa, Mexico, Feb., 1868. Range.—Western Mexico, from Michoacan north to northern Sinaloa, and east to Guanajuato. Remarks.—Bonaparte described his “Syrniwm squamulatum” in Con- spectus Generium Avium, I, Pt. 1, June 24, 1850, p. 53, based on Strix squamulata ex Lichtenstein manuscript. The type of this was in the Leyden Museum and labeled simply ‘‘Mexico.”’ He characterized it as having small buffy-white spots. Specimens from central and northern Oaxaca show this character and otherwise agree with his description. It is therefore likely that the type came from the region of Oaxaca. A series of Ciccaba v. centralis and C. v. squamulata from this and other parts of southeastern Mexico and from Central America contains not one specimen with upper parts like those of C. v. amplonotata from Michoacan and northwestward. There is no difference in average measurements, but the plumage around the head and neck is longer and looser. Six specimens of C. v. amplonotata have been examined by the writer. 30—Proc. Bion. Soc.

THE THIRD SPECIMEN OF ELAPERB. LOSACEA In 1888 Cope described Coluber rosaceus, the type specimen. coming from Key West (Proc. U.S. Nat. Mus. 1888, p. 388). As a Copeian species, based on a single specimen, it was disre- garded, more or less, until, more than thirty years later, the second example was found, on Big Pine Key. Barbour, into whose hand this came, was as much impressed with the animal as Cope had been and promptly resurrected the species, now Elaphe rosacea (Copeia, No. 84, 1920, p. 68). Since then many visitors to the Lower Florida Keys, myself among them, have searched in vain for this striking snake. I now have before me the third specimen, alive, and have compared it with Elaphe guttata, the widespread form whose range includes the area in which rosacea may be found. I am indebted to Messrs. R. F. Deckert and Al. Pflueger, of Miami, Fla., for the privilege of examining this specimen. It was collected by Mr. Pflueger on Little Pine Key. The species apparently still survives on the few isolated Keys which support hammocks. Color, rather than scalation and the pattern of the markings, will enable rosacea to be differentiated from guttata. The ground color of rosacea is a dark plumbeous in contrast to the light buff of guttata. The dorsal saddles, lightest anteriorly, are a darker red flecked with orange, differing from the even vermilion of the guttata saddles. The square black ventral spots are much the less distinct in rosacea which has the posterior two-thirds of the venter a bright orange, contrasting with the white ventral ground color of guttata. The species is characterized by the presence of four dark longitudi- nal stripes, a lateral and a median-dorsal pair. In the present specimen these stripes vary in intensity, being most pronounced immediately after 31—Proc. Bion. Soc. WasH., Vou. 46, 1933. (158) abittnann ene 154 Proceedings of the Biological Society of Washington. sloughing of the skin. Since guttata has been known to bear, occasionally , similar stripes, the character is not infallible. Finally, preservation of rosacea is accompanied by marked fading of the red pigment of the saddles and lateral spots, as well as the longitudinal stripes. The dark dorsal ground color, however, remains quite pro- nounced—even in the type, after nearly half a century. This is quite the opposite from the case of guttata, in which the red pigmented areas remain well defined. f~> 9 DO in) Vol. 46, pp. 155-156 October 26, 1933 PROCEEDINGS OF THE Rite ewplanth ai BIOLOGICAL SOCIETY OF WASHINGTO! if oa / 1 l= | MAR 2: DESCRIPTIONS OF TWO NEW BIRDS-FROM SOUTHEASTERN SIAM. 2 BY J. H. RILEY.! In these Proceedings, volume 48, 1930, pages 189-192, three new birds were described from southeastern Siam from collections made there by Dr. Hugh M. Smith. In the same collection there were two forms that could not be determined at that time. Further study has convinced me that they are apparently undescribed. ‘The first is a bulbul and the second a wren-babbler. They may be known from the following de- scriptions: Ixos canescens, sp. nov. Type, adult male, U.S. National Museum, no. 324,490, Kao Kuap, Krat, southeastern Siam, December 24, 1929. Collected by Hugh M. Smith (original no. 3560). Similar to Ixos griseiventer (Robinson and Kloss) of south Annam, but the pileum a lighter brown with the shaft streaks reduced and less conspicu- ous; the back much darker citrine; the tail above dusky towards the tip not citrine for its whole length; tail below dusky instead of citrine; under tail coverts darker; the chest a more brownish gray and the shaft streaks much reduced in width and cartridge buff instead of grayish white. Wing, 94; tail, 91.5; culmen, 20.5; tarsus, 18; middle toe with claw, 16.5 mm. Remarks.—Dr. Smith took a female two days later at the same locality. It does not differ essentially from the male and measures as follows: wing 92; tail 86; culmen 20; tarsus 18; middle toe with claw, 16.5 mm. In my opinion, [xos griseiventer does not belong in the same form-group as Izos macclellandi tickelli, and as Ixos canescens instead of being inter- mediate between tickella and griseiwventer is quite different from both and the ranges of all three are separated by wide stretches of country where no intermediates are known to occur, therefore griseiventer and canescens should be recognized as distinct until forms of intermediate character are discovered. Birds of the Ixos macclellandi group of forms are larger with 1Published by permission of the Secretary of the Smithsonian Institution. 32—Proc. Biou. Soc. Wasu., Vou. 46, 1933.

Corythocichla brevicaudata cognata subsp. nov. Type, adult male. U.S. National Museum, no. 324,378, Kao Sabab, Chantabun, southeastern Siam, January 7, 1930. Collected by Hugh M. Smith (original no. 3625). Similar in color to Corythocichla brevicaudata striata but the gray of throat deeper, the streaks much paler and upper parts darker, less ru- fescent. Description.—Pileum and back snuff brown, lighter along the shaft and with the outer margins of the feathers seal brown; rump cinnamon-brown; forehead, superciliary, and sides of face, including the ear coverts neutral gray; chin and throat pale neutral gray streaked with neutral gray; breast cinnamon buff, deepening to mikado brown on the belly and crissum; sides and flanks cinnamon-brown; tail above mummy brown; the closed wing the color of the tail, the greater wing coverts and remiges with a triangular light buff spot at the tip; the primaries and outer secondaries blackish on the inner web. Wing, 57; tail, 35; culmen, 14; tarsus, 23; middle toe with claw, 19.5 mm. Remarks.—Doctor Smith secured a male and female at the type locality and a male at Kao Kuap, Krat. The female from the type locality differs from the type in being much lighter on the breast, but the chin and throat are more heavily streaked. The male from Kao Kuap has the chin and throat more heavily streaked than the type and even grayish streaks on the breast and belly and the center of the breast is much lighter, near tilleul-buff. The female from the type locality measures: wing, 57; tail, 35; culmen, 13; the male from Kao Kuap: wing, 61; tail, 41; culmen, 14 mm. Corythocichla griseigularis Delacour and Jabouille from Bokor, 8. Cam- bodia, is evidently closely related, but it is described as having a uniform gray throat and chest. Corythocichla leucosticta, Corythocichla venningi and two or more of the Indo-Chinese forms with longer wings and longer tails do not belong to the brevicaudata form group at all, in my opinion.

In describing? not long ago a new davallioid fern genus, Ormoloma, based upon Saccoloma Imrayanum, a rare but com- paratively well-known plant of the Lesser Antilles and the Guianas, reference was made to a closely related form occurring in the mountains of Costa Rica and western Panama. This is described herewith and contrasted with the genotype species. Ormoloma Standleyi Maxon, sp. nov. Rhizoma tenue repens, paleis divaricatis brunneis majusculis praeditum. Folia subdisticha erecta plura, omnino glabra, stipitibus quadrangulari- bus tenuibus laminas pleurumque aequantibus; laminae oblongae, 1- pinnatae, apice acutae; pinnae subaequales alternae obliquae elongato- lanceolatae crenulatae, e basi petiolulata anguste cuneato-excavatae; sori solitarii terminales intramarginales; indusia transverse oblonga vel anguste lunata, basi lata affixa, marginis dentibus subrotundis herbaceis immutatis multo minora.

The present species was long ago reported from Costa Rica by Baker’ as Davallia Imrayana, on the basis of the Cooper specimen above cited, and is presumably the plant listed more recently by Christ* as Saccoloma Imrayanum. It is, in fact, closely related to Ormoloma Imrayanum, but differs consistently in several characters, which may be summarized as follows: Stipes castaneous, sharply quadrangular, 1-1.3 mm. thick; pinnae 17-23, oblique, crenulate, 7-10 (13) mm. broad, not strongly inaequilateral at the narrowly cuneate-excavate base; sori SSS (U5) mas lon Oeste ee ct pe ne O.

Of the few tropical American species of its subgroup L. Skutchit need be compared only with the Antillean L. agualupianum Spring and with the continental L. callitrichifolium Mett., of which L. dichaeoides Maxon? is probably a synonym. It differs notably from both in its long-acuminate leaves, which are borne in eight ranks rather than four. In sporophyll characters L. Skutchit resembles L. aqualupianum, but in that species the leaves are, at most, barely acute and the costa is plainly elevated through- out. It may be even more readily distinguished from L. callitrichifolium, in which the leaves are obtusely oblong-oval to broadly subspatulate and the sporophylls for the most part congested. 2Proc. Biol.

A NEW SPECIES OF BRAZILIAN TERMITE, FEATUR- ING AN INTERMEDIATE SOLDIER-WORKER INDIVIDUAL. BY THOS. E. SNYDER, Bureau of Entomology, U. S. Department of Agriculture. ““TIntermediate’’ forms among the castes of termites are rather rare. It is true that intermediate forms among the colonizing reproductive adults, ranging from apterous to macropterous forms, are not uncommon; but when we consider the sterile soldier and worker castes, intermediates are very rare. In colonies of Kalotermes (K.) occidentis Walker, of Arizona and western Mexico, all soldiers have wing pads or traces of wings, whereas among most other primitive termites wing pads are only occasionally found on soldiers. ‘These soldiers are not fertile, but are merely reversions to the ancestral winged termite. Where fertile soldier-like forms do occur, as in species of Termopsis of the Pacific Coast, the form of the soldier is not normal and they may be considered as intermediates between the ancestral winged sexual adult and the normal sterile soldier. _None of the higher more specialized termites have soldiers with wing pads or fertile soldier-like forms and no fertile workers of any termite have as yet been discovered. Among the termites classified between the primitive and the higher termites, such as those in our common genus Reticulitermes of North America and the north temperate regions of the world, a rare abnormality has been found. In the species tibialis Banks, of the western States, a male half worker, half soldier form was found over 15 years ago near Missoula, Mont. The head has the characteristic color of the soldier caste and is slightly longer than the head of the worker. The mandibles and labrum are typically worker-like, but are extended as in the soldier. This 35—Proc. Bion. Soc. WAsH., Vou. 46, 1933. (161) eine, ann eee eo Oye cr erst hae Faas Sa TS 162 Proceedings of the Biological Society of Washington. form may merely be a worker of abnormal development or it may be an intermediate between the worker and soldier castes. The soldier develops from a worker-like form to the soldier-like form during a quiescent stage, thereby in its ontogeny expressing the phylogeny of this caste, according to Emerson’s theory. If something happens during this transformation, abnormalities or intermediates may result. Recently a more definite intermediate soldier-worker form was found in a vial among a small collection of termites sent to me for identification. A description of this termite and of the intermediate follows. Nasutitermes (N.) myersi, n. sp. Soldier.—Head castaneous brown, large, neither round nor oval; in profile, nearly a straight line slightly concave in middle and convex at base of nasus; with dense, fairly long hairs and longer bristles. Nasus short and conical. Mandibles vestigial, but plainly visible. Antennae with 13 segments; third segment nearly as long as second and fourth together; fourth segment longer than second but shorter than fifth. Pronotum lighter colored than head, yellow-brown; with dense, fairly long hairs and longer bristles; markedly roundedly emarginate in middle. Abdomen yellow-brown; tergites with dense, fairly long hairs and a row of longer bristles at the base of each tergite. An intermediate soldier-worker form has the color of the soldier, but has a shorter nasus than the soldier, and worker-like mandibles. Other differ- ences are that this intermediate, like the worker, has 14 segments to the antennae, whereas the soldier has only 13. The third segment is merely longer than the second or third, whereas in the soldier the third segment is nearly as long as the second and third segments together. In general, this form is more worker-like than soldier-like. (See figs. 1 and 2.) In the measurements in the following table the minimum measurements are more normal than the maximum for the worker and the maximum more normal for the soldier. nyder—A New Species of Brazilian Termite. 163 Measurements of the soldier in comparison with the worker and intermediate form: Soldier Worker Intermediate mm. mm. mm, matallen othe. 8 coh eee 5 -6 5.3 - 6 5.1 Length of head with nasus..........

EWING, United States Bureau of Entomology. In his revision of the American lice of the genus Pediculus (Ewing, 1926) the writer pointed out that those species oc- curring on American monkeys were distinct from those found on man. In fact he created for them a new subgenus, Para- pediculus, and gave distinguishing characters for it. Since that time many specimens have been taken from American monkeys, through the cooperation of the National Zoological Park. A study of this additional material confirms the findings of the writer in his paper of 1926. It should be stated, however, that in one species observed (apparently an undescribed form) the lateral lobes of the pleural plates are very poorly developed and are present only on pleural plates IV and V. Last year (1932) material from chimpanzees at the London Zoological Gardens was received. The first lot contained only three specimens, but the characters of these were so striking that a third subgenus was erected (Ewing, 1932) for the species they represented. This subgenus, Paeni- pediculus, was much farther removed from the typical subgenus than Parapediculus. The receipt of additional material of the type of Paenz- pediculus, P. simiae, and in particular the eggs and first nymphs included in the lot, have enabled the writer to elaborate somewhat on the characters of the subgenus Paenipediculus. Since the species of Pediculus from New World monkeys constitute a subgenus, the question may be asked: Do those from Old World apes constitute a subgenus? The present writer is not in a good position to answer this question, as he has seen specimens of only one of the four species involved. However, a review of the literature indicates that only one of these three other species, Pediculus schdffi Fahrenholz (see Fahrenholz, 1915), belongs to Paenipediculus. This conclusion is reached notwithstanding the claims of Nuttall (1919). He stated, “‘We have recently encountered this louse 36—Proc. Brox. Soc. Wass., Vou. 46, 1933. (167) 168 Proceedings of the Biological Society of Washington. [P. schdffi] in the Denny Collection at Oxford . . .’’ and concluded as follows regarding it: ‘‘ Judging from the author’s figures and measurements he must have indeed examined very few specimens. The only indications he gives that may point to a new species are, (a), the presence of a blunt spur basally on coxa II in 9 and larva, (b) the very prominent lateral protrusion of the last abdominal segments in a 9, (c) the more tapering basal end of the egg; his further ‘specific’ characters may be dismissed as without significance.’’ Nuttall finished his discussion of Pediculus schdffi with this statement: ‘‘On the evidence at hand, P. schdéffi must be regarded provisionally as a race of P. humanus.”’ It should be stated, however, that there are characters mentioned by Fahrenholz and others that are apparent in the figures he gives which clearly indicate that Pediculus schdffi belongs to Paenipediculus. As a matter of fact, only one of the six characters given in the original diagnosis of Paenipediculus is discussed by Nuttall. The other two ape-infesting species of Pediculus are P. assimilis Fahren- holz and P. friedenthali Fahrenholz. According to the descriptions and figures given by Fahrenholz these species do not belong to Paenipediculus. Could they have been stragglers on their hosts, gibbons, from some other primates? In order to answer this point the writer has searched several scores of study skins representing several species of gibbons without finding as much as a single egg or louse specimen. It would appear to some that this would indicate either that gibbons were not the natural hosts of these species or that they were rare in nature. The writer would hesitate, however, to draw such conclusions. When the writer described the type of Paenipediculus, P. simiae, there was little assurance that it actually had the chimpanzee as a natural host. In order to learn more about the conditions of the host previous to the taking of the lice, inquiry was made of Dr. B. V. Wigglesworth, the sender of the first lot of material, to get any data he could supply. He not only obtained such information but forwarded to me the additional material (already mentioned), which was collected by Colonel A. E. Hamerton at the London Zoological Gardens, together with the following note from Colonel Hamerton, who collected the first lot of material: “The first lice I sent to you were taken from a chimpanzee ‘ Andrew’ that was brought to England from West Africa (Gold Coast) early in the year and was deposited in the ‘Zoo’ here last July. The lice were found on it a few days after arrival—and they have spread to 2 other chimpanzees that shared its den foratime. I send to you herewith some living and dead specimens from the ‘Chimps’ that were infected from ‘Andrew.’ I have not been able to find them on any other primates—though I have not searched all the representatives of this order in our collection. Iam unable to say that the chimpanzee is the natural host of the louse. The 2 gorillas will not permit any one to handle them so it is not possible to say whether they harbor Phthirus gorillae, but they show no signs of lousiness.”’ Thus the indications are that the host from which the type of Paenipedi- culus was taken was infested in nature, and that the louse described did in fact belong to the chimpanzee. Ewing—The Taxonomy of Pediculus linnaeus. 169 Other facts, also, have been brought to bear on the host problem which show conclusively that the louse described is in fact a chimpanzee louse. They are here given: Several years ago the writer collected eggs from chimpanzee skins in the United States National Museum. He even obtained the fully formed first nymphs from some of these eggs, but because of the lack of more mature individuals, and because little was known at that time in regard to the history of the host individuals from which the eggs were taken, no description of them was made. After publishing the description of Paeni- pediculus sumiae the writer began to wonder if these eggs could possibly be those of the described species, but could come to no conclusion, as no eggs of Paenipediculus simiae were available for comparison. Fortunately, however, in this second lot of material sent from the London Zoological Gardens there were some eggs. ‘These were mounted and studied. They proved to be identical with those I had taken previously from chimpanzee skins. An investigation as to the source of the egg material obtained from the study skins at the National Museum shows that four of the five lots taken came each from the skin of a different individual chimpanzee killed in nature,! and one came from a young chimpanzee that had been kept in captivity for about a year in Africa. Thus we have the desired proof that Paenipediculus simiae has the chimpanzee as a natural host. Fic. 1.—Eggs of two man-infesting and two ape-infesting louse species, all drawn to the same scale; a, Pediculus humanus; b, Pediculus (Paeni- pediculus) simiae; c, Phthirus gorillae; d, Phthirus pubis. 1This information was obtained from the records of the collector of the chimpanzee skins, C. R. Aschemeier. Mr. Aschemeier, who is a taxidermist in the United States National Museum, also was interviewed. 170 Proceedings of the Biological Society of Washington. Paenipediculus was described as a subgenus of Pediculus and should be regarded as such. However, an examination of further material represent- ing eggs, first nymphs, other nymphs, and several females necessitates a revision of the generic diagnosis. In the original description of the sub- genus it was stated that the first three pairs of pleural plates were absent. However, by clearing a female specimen of the second lot of material with potassium hydroxide and staining in acid fuchsin it was found that each of these pleural plates was represented by a ring of chitin. These vestigial pleural plates do not show up in unstained specimens, as the chitin has little or no natural pigment. An examination of the legs of the first nymphs shows that the first tarsal claws are long, sharp, and slender; while the second and third tarsal claws are stout and have their tips rounded (Fig. 2, c). This marked differ- ence in the tarsal claws suggests a condition found in the first nymphs of Phthirus (Fig. 2, a and b) and possibly indicates a phylogenetic relationship between the Pediculidae and Phthiridae. In order to show more clearly the differences between the first nymphal instars of some related primate-infesting lice a key is here given to the two species occurring on man, the one species known from the gorilla, and the type of Paenipediculus from the chimpanzee. 1.

The different varieties of Pediculus hwmanus Linnaeus and apparently the two species described by Fahrenholz from gibbons belong to the typical subgenus. All of the American monkey-infesting species are included in Parapediculus, while the two lice reported from the chimpanzee belong to Paenipediculus. The louse of the gorilla is not a Pediculus. The characters of the nymph (first nymph) are typical of Phthirus. The valid species and varieties of Pediculus, together with their type hosts, are here given.

Nuttall (1919) has given a list of synonyms. It should be stated, however, that a more careful study of some of these so-called synonyms may show that they represent good races or subspecies. By all odds the most important taxonomic character in Pediculus is the shape of the pleural plates. These have not been critically studied in some of the Old World species. The position and size of the spiracles is another important character that has attracted but little attention from workers in the past.

Among the collections of the United States National Museum are two small skinks of the genus Hwmeces which appear to be unnamed. Due to the courtesy of Dr. Leonhard Stejneger and Miss Doris Cochran, both of the Museum, I have been given the privilege of describing these interesting novelties. Both forms are from the western part of Mexico; one, Humeces parvulus, from Nayarit and Sinaloa; the other, Hwmeces par- viauriculatus, from Sonora. This territory is much less known than the plateau region, and it is highly probable that other interesting species await discovery in this part of Mexico. Eumeces parvulus, sp. nov. Type.—Catalogue No. 56903, United States National Museum. Col- lected, Tepic, Nayarit, Mexico, April 10, 1910. Diagnosis.—A small species, having a dorsolateral line beginning on rostral, passing back on side of head, and neck, and disappearing about the middle of the back; a lateral light line from rostral to ear, following the lower edge of labials; no median light line or bifurcating lines on head; four supraoculars; no postnasal; one postmental; parietals enclose inter- parietal; frontonasal touches frontal; a relatively very large primary tem- poral, larger than lower secondary temporal, and in contact with it. Twenty-four scale rows about the middle of the body; postgenial large, bordered on inner edge by a scale wider than long. Description of type.—Part of rostral appearing on anterior tip of snout small, separated from frontonasal by the paired supranasals; frontonasal broader than long, angular anteriorly, rounded posteriorly, forming a considerable suture with the frontal, and in contact laterally with the anterior loreal; frontal more than a third longer than its distance from tip of snout, truncate anteriorly, rounded behind, constricted at a point about one-third the distance from the posterior edge, broadly in contact with the three anterior supraoculars; frontoparietals distinctly rectangular, mak- ing a median suture less than one-third of their length; interparietal rather 37—Proc.

Thompson) and a second, No. 47667 U.S. N. M. collected at Plumosas, Sinaloa (Coll. Nelson and Gold- man) are at hand for comparison. The first of the two shows the following variations in scalation: 62 instead of 63 scales from head to above vent; about 15 scales about ear; there are 14 instead of 13 lamelle under longest toe; the adpressed limbs are very narrowly separated when adpressed while in the larger specimen they are 178 Proceedings of the Biological Society of Washington. separated by 8 millimeters. The color of this form is darker, appearing brownish above with the dorsolateral lines cream and well differentiated to about midway on body. The lateral stripe is difficult to differentiate from body color; chin and throat cream color; the color of the abdomen appears somewhat in darker and lighter lines, a character also visible but dim in the type; under side of tail lighter than abdomen, the median part with a lighter streak; regenerated tip on tail, cream. No. 47667 U.S. N. M. from Plumosas, Sinaloa, Mexico, shows a number of abnormal peculiarities. The frontonasal and prefrontals are fused into a single scale and this separated from the frontal by a partly obliterated suture; the posterior constriction of the frontal is very slight; the enclosed interparietal is as broad as long; the primary temporal is as large as upper secondary but both are slenderer in type; the head appears to be proportion- ally wider; there appears to be only 22 scale rows (the specimen has been injured, and it is difficult to make an accurate count at middle of body); other scales and markings are similar, generally, to type, the line behind ear being wholly absent; the color above is grayish brown, the lateral brown line very distinct. If the character of the fused frontonasal and prefrontals were not ab- normal, it would be necessary to recognize this as a distinct species. How- ever, I strongly suspect it is abnormal and for the time being it will be placed under this species. Similar anomalies have been observed in specimens of several other species. Remarks.—The relationship of the species is not clear, and appears to show more characters in common with the newly described form, Hwmeces parviauriculatus, as I have suggested under that species; and possibly also to a newly described form, Humeces ochoterenae Taylor, from the high mountains of Guerrero, Mexico.

The type is in poor condition; many of the scales have slipped, and the abdomen is somewhat softened. The viscera have been removed. The tail is present, but is broken into two pieces; the tip is regenerated; the fore feet have been dried. Despite this, none of the essential characters are obscured. The relationship of the form is not clear. It is probably a degenerate form and may be distantly related to Humeces parvulus described in this paper. It differs in having a smaller ear opening overlapped by the scales on its anterior border; the character of the temporals and the character of the scales at the insertion of arm and the unenclosed parietal; the character of the frontal and the relationships with the supraoculars; the wide separation of the seventh labial from the ear and the different shape, relative size and character of the scales surrounding the body. It is probably totally unrelated to the recently described Humeces dicei Ruthven and Gaige. This form, judging by the character of the temporals, belongs to another section of the genus. The known EHumeces fauna of Sonora is indeed meager, this being the only specimen I am aware of, certainly from this large state. Humeces callicephalus Bocourt and EHumeces humilis Boulenger and some form Eumeces brevirostris Giinther may be expected to occur. Its relationship appears to be with none of these forms.

BIOLOGICAL SOCIETY OF WASHINGTON. ee i al ial CRITICAL NOTES ON AMERICAN VULTURES. BY HERBERT FRIEDMANN. The following observations and notes were made while study- ing the Cathartidae in connection with the continuation of Ridgway’s unfinished work, The Birds of North and Middle America. 1. The Genus Coragyps. Current literature treats with this monotypic genus as comprising two races, the North American black vulture, C. atratus atratus (Bechstein) and the South American form, C. atratus foetens (Lichtenstein). The latter subspecies is said to be smaller, but otherwise not different, from the nominate race. However, there has been considerable difference of opinion among investigators as to whether or not the two forms were constant in their differences. Thus, Todd (Ann. Carnegie Mus., xiv, 1922, 142) treated the black vulture binomially; Wetmore (Bull. 133, U.S. Nat. Mus., 1926, 90) called his South American birds C. atratus foetens, but wrote that in a limited series he was unable to find any sharply trenchant difference between northern and southern birds. Through the kindness of Mr. John T. Zimmer, of the American Museum of Natural History, I have been able to borrow a series of South American birds to amplify the material in Washington. All in all I have seen 10 specimens of foetens (from Argentina, Chile, Ecuador, and Brazil) and twice that many of typical atratus. My findings are as follows: South American birds have wings ranging from 412-432 mm. (one Chilean speci- men 405 mm.); North American birds measure, in this dimension, from 415-454 mm. The average of the South American birds is 421 mm., that of the North American series 432.8 mm. It may be seen that although North American birds may achieve considerably greater proportions than South American specimens, yet, practically all (8 out of 10) of the latter group may be matched by North American birds. In other words, if we accept size as a valid criterion of race, we can identify none of the South American birds by this means, and only the larger examples from North America. Not only are the variational limits of foetens almost wholly 1Published by permission of the Secretary of the Smithsonian Institution. 39—Proc. Brot. Soc. WasH., Vou. 46, 1933. (187) 188 Proceedings of the Biological Society of Washington. contained within those of atratus, but the difference between the averages of the two is less than 3% of their size. Therefore, I conclude that we are not justified in separating foetens from atratus and the name of the black vulture throughout its entire range is simply Coragyps atratus. 2. The genus Cathartes. Study of a long series of birds from North and Central America and the West Indies has revealed the existence of a hitherto undescribed subspecies, the one inhabiting western North America. No name being already available for this form, it may be called Cathartes aura teter, subsp. nov. Type.—Adult female, coll. Biological Survey, U. S. Dept. Agriculture 285275, collected at Riverside, California, April 12, 1892, by A. H. Higgin- son. Subspecific characters.—Similar in coloration to C. a. aura and C. a. septentrionalis, but with the small wing of the former and the long tail of the latter race. Measurements of type.-—Wing (chord) 504; tail 258; culmen from cere 25; tarsus 62 mm. Remarks.—Of this new form I have seen 33 adult specimens; their dimen- sions are as follows (sexes alike): wing 480-528 [one specimen 543] (507); tail 252-282 (262.4); culmen from the cere 24-26 (24.9); tarsus 62-68 (65mm.). Compared with this are the following data on 24 adult specimens of septentrionalis: wing 530-563 (545.6); tail 260-289 (279.2); culmen from the cere 23-26.5 (25.1); tarsus 60-67 (64.2 mm.). Of the nominate race 20 adults show the following size variations: wing 475-514 (492.2); tail 235-250 (246); culmen from the cere 20.5-25.5 (24.8); tarsus 63-68 (65.4 mm.). The ranges of the three forms of the turkey vulture may be outlined as follows: 1. C. a. aura: The lower, tropical portions of Mexico from Vera Cruz; Quintana Roo, Yucatan; Mazatlan; Sinaloa; Tres Marias Islands; south through Central America to Panama (Farfan; Canal Zone; Barro Colorado) and to northern Colombia (Rio Frio; Magdalena; Mamatoco, Santa Marta); also in the Bahamas, Cuba, Isle of Pines, Jamaica, Porto Rico (introduced), and the Virgin Islands; possibly formerly in Hispaniola. 2. C. a. septentrionalis: Southern Ontario, central New York, Connecti- cut, and New Jersey, Ohio, Indiana, Illinois, and eastern Iowa, south through Missouri and Arkansas to Louisiana, the Gulf States generally and to southern Florida (at least to Miami and Cedar Keys; no specimens seen from the extreme tip of the peninsula or the keys, where it is not im- possible that aura may occur). Breeds north to southeastern Michigan, southeastern New York and Connecticut, winters throughout its range except north of the Ohio Valley; casual in northern Ontario, northern New England, New Brunswick, and Newfoundland. (One record from British Columbia!) Friedmann—Critical Notes on American Vultures. 189 3. C. a. teter: Austral zones from southern British Columbia, central Alberta, Saskatchewan, southern Manitoba, Wisconsin, northern Minne- sota, and southwestern and south-central Michigan south to southern lower California, northern Mexico (Sonora (Guadaloupe Canyon), Chihuahua, and Tamaulipas south in the plateau to Michoacan), east to eastern Texas, Oklahoma, Kansas, Nebraska, the Dakotas, Minnesota, and south-central Michigan, intergrading with septentrionalis in southeastern Michigan, and probably in western Missouri. Winters from California to Nebraska and southward. For the loan of material used in this study I am indebted to the authori- ties of the following institutions: The Museum of Comparative Zodlogy, Cambridge; the American Museum of Natural History, New York; the Carnegie Museum, Pittsburgh; the Museum of the University of Minne- sota, Minneapolis; the Museum of the University of Iowa, Iowa City; the University Museums, University of Michigan, Ann Arbor. Owing to the fact that the western form extends eastward as far as south central Michigan, it became imperative to know to which form the name septentrionalis should apply. Septentrionalis is based on Maximilian’s, Prince of Wied, birds from New Harmony, Indiana. Apparently no museum possessed a topotypical specimen and it was not until Miss Louise M. Husband, Librarian of the Workingmen’s Institute, New Harmony, very kindly took the trouble of having a specimen shot and sent to the United States National Museum, especially for use in this study, that it was possible to settle this matter. The New Harmony bird is of the large, eastern race, to which the name septentrionalis must therefore be applied.

Recent study of the material of the genus Mutisia in the U.S. National Herbarium and a hasty examination of that in the Gray Herbarium has led to the detection of a handsome new species which is here described. In addition, two previously described species are reduced to what appears to be their proper rank, one as a variety, the other as a synonym. Mutisia venusta Blake, sp. nov.

Stem about 3 mm. thick; internodes 2-14 cm. long; rachis of leaves 5.5-13 cm. long (excluding tendril), the tendrils up to about 3 cm. long; lowest pair of leaflets small, about 7 mm. long, obliquely ovate, semicordate, the others mostly 2.38-4.2 cm. long, 9-14 mm. wide, rounded at base, firm, entire, flat, prominulous-reticulate beneath, lanuginous at base of costa; involucre subcylindric, slightly tapering upward when fresh and then bright green, about 7—8-seriate, the phyllaries not very numerous, the outer ones 7-20 mm. long, 2.5-6 mm. wide, the inner 7-9 mm. wide, finely ciliolate and with a small woolly tuft at apex, otherwise glabrous; ray corollas scarlet, the tube 7 cm. long, the limb sharply 3-dentate, 3.2 cm. long, 9 mm. wide, the achenes (immature ?) 4 mm. long, the plumose pappus 2.2 cm. long; disk flowers about 17-18, 6.2 cm. long (tube 1.1 cm., outer lip linear, 3-toothed, 4-nerved, 5.1 cm. long, 2.5 mm. wide, inner lip of two linear divisions 0.8 mm. wide equaling the outer lip, one of them sometimes con- nate for some distance with the outer lip), the achenes (immature ?) 40—Proc.

Herb.); same locality, 16 July 1915, Cook & Gilbert 1879. A species of the Sect. Pinnatisectae, related to M. viciaefolia Cay. and the doubtfully distinct M. peduncularis Cay., but readily distinguished from the extensive series of these species examined by its acuminate outer phyl- laries, those of the species mentioned being obtuse or rounded. Mr. Cook informs me that this plant flowers in winter, in a locality where the tem- perature goes well below the freezing point every night. MoTISIA DECURRENS var. patagonica (Phil.) Blake. Mutisia patagonica Phil. Linnaea 28: 711. 1858. Mutisia patagonica Phil., based on material collected by Fonk ‘‘ad marginem lacus Nahuelhuapi,”’ was described as similar to M. decurrens Cav., but with the leaves and ligules arachnoid-lanuginous beneath. In the U. 8S. National Herbarium is a sheet collected by Dr. Ctto Buchtien (no. 60) at San Carlos de Bariloche (on Lake Nahuelhuapi), 4 Feb. 1905, bearing two specimens, one of which is typical M. decwrrens Cav., the other obviously of the same species but with the leaves canescent-tomentose beneath. The ligules are more or less arachnoid-tomentose beneath in both. In the Gray Herbarium is another sheet from Buchtien, similar enough to be of the same collection but dated 16 Feb. 1905 and distributed by Baenitz under the number 1351, in which the leaves are rather thinly gray-tomentose beneath, in some cases more or less completely glabrate. The occurrence of the two forms together and the lack of any other distinc- tive features show that M. patagonica is best treated as a variety of M. decurrens, distinguished by the same character as several variants already recognized in other species of the genus. MoTISIA ANDERSONI Sodiro; Hieron. Bot. Jahrb. Engl. 28: 80. 1900. Mutisia sagittifolia Blake, Bot. Gaz. 74: 428. 1922. The identity of Mutisia sagitizfolia, based on Holway 941 (of 1920) from Mt. Pichincha, Ecuador, with the earlier M. andersoni is proved by ex- amination of a photograph in the Gray Herbarium of Hieronymus’ type (Sodiro 63/1) at Berlin, in connection with the study of two additional specimens in the U.S. National Herbarium (Mille 756, from Mt. Pichincha, 1917, and Rimbach 206, from Prov. Riobamba, Ecuador, alt. 3300 m.). The toothed cauline wings mentioned in the original description of M. andersoni are very obscure or wanting in the specimens examined. In general, it is evident that distinctions drawn from the presence or absence of wings on the stem, and their degree of development when present, must be applied with caution in this genus. 1The dates of publication of the 6 hefte of vol. 28 of Linnaea, as shown by the original covers of the parts in the copy in the U. S. Department of Agriculture, are as follows: Heft 1 (p. 1-128), Aug. 1856; Heft 2 (p. 129-256), Sept. 1856; Heft 3 (p. 257-384, pl. 1-2), Jan. 1857; Heft 4 (p. 385-512), June 1857; Heft 5 (p. 513-640), Aug. 1857; Heft 6 (p. 641- 767), Feb. 1858. The whole volume is usually cited as of 1856, the title-page date. ee #~ Vol. 46, pp. 193-194 October 26, 1933 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON A NEW SUBSPECIES OF THE SNAIL KITE, ROS- TRHAMUS SOCIABILIS (VIEILLOT). BY E. W. NELSON AND E. A. GOLDMAN. We are indebted to Dr. Herbert Friedmann for directing our attention to an interesting new geographic race of fRos- irhamus sociabilis collected by us during our work in Mexico. The type, a male, while full grown is in the immature plumage. Two other full grown young males in the Biological Survey collection taken at Flores, Lake Peten, Guatemala, by Harry Malleis, June 18, 1923, were evidently residents. Still another specimen of the same form in fully adult plumage in the National Museum, lacks full data. It was probably collected by F. Sartorius as the locality is given, with a query, as Mirador, the name of his coffee plantation in Vera Cruz. Rostrhamus sociabilis major, subsp. nov. MEXICAN SNAIL KITE.

Original number 1980. Distribution.—Lowlands of eastern Mexico and Peten district of northern Guatemala. General characters.—Color practically as in Rostrhamus socialis socialis of South America and R. s. plumbeus of Florida; size largest of the known forms of the species; bill much larger and heavier; wings and tail longer. Measuremenis.—Type: Wing, 380 mm.; tail, 198; tarsus, 52; culmen from cere, 30; culmen including cere, 38. Remarks.—The new form is readily distinguished by the remarkable size of the bill. It agrees closely in color, however, and other essential characters with the more northern and southern subspecies. 41—Proc. Bion. Soc. WasH., VOL. 46, 1933.

In dealing with cotton rats from western Mexico, J. A. Allen (Bull. Amer. Mus. Nat. Hist., vol. 22, art. 12, p. 210, July 25, 1906) states that Szgmodon allent Bailey, described from San Sebastian, Mascota, Jalisco is ‘‘beyond question a syno- nym of mascotensis.’”’ Sigmodon mascotensis had been described by Allen from the same locality. Examination of the types of mascotensis and allent shows that the former is a member of the Sigmodon hispidus group as assigned by Bailey (Proc. Biol. Soc. Washington, vol. 15, p. 108, June 2, 1902), while contrary to Allen’s conclusion quoted the latter is a distinct species of the Szgmodon fulviventer group. The cotton rats of the fulviventer group are rarer and much less widely distributed than those of the hispidus group. Two new members of the genus based upon scanty material, are here regarded as specifically distinct, owing to salient characters presented, and the absence of evidence of intergradation with any others of the group. A new pocket gopher of the Ortho- geomys grandis group is also described. Orthogeomys grandis annexus, subsp. nov. TUXTLA POCKET GOPHER. Type.—From Tuxtla Gutierrez, Chiapas, Mexico (altitude 2,600 feet). No. 75949, @ adult, skin and skull, U. S. National Museum (Biological Survey collection), collected by Nelson and Goldman, September 11, 1895. Original number 8418. Distribution.—Arid tropical valley of the Chiapas River in the interior of the state of Chiapas; limits of range unknown. General characters.—A sparsely and coarsely-haired subspecies, closely resembling Orthogeomys grandis scalops of the arid lowlands near Tehuan- tepec, Oaxaca, in external appearance, but cranial details quite distinctive. Differing from Orthogeomys grandis grandis of the highlands of Guatemala in thinner, coarser pelage, and in important skull characters, notably the 42—Proc. Bion. Soc. Wasx., VOL. 46, 1933. (195) 196 Proceedings of the Biological Society of Washington. straighter upper outline of cranium. Smaller than Orthogeomys grandis nelsoni of the high mountains of northeastern Oaxaca, with thinner pelage and divergent cranial features. Color.—Type: Upper parts and outer surfaces of forearms and thighs near Mars brown of Ridgway; under parts and inner surfaces of limbs similar to upper parts, but somewhat lighter in tone, the pelage so sparse that the naked skin is clearly visible; feet very scantily clothed with light brownish hairs; tail naked, the skin yellowish. Skull.—Similar in size and general form to that of O. g. scalops, but less angular; upper longitudinal outline nearly straight—straighter even than in scalops; rostrum more slender; nasals broader posteriorly; outer surface of zygoma narrower at point of union of maxilla and jugal; supraorbital borders of frontals more nearly parallel, with a less distinct interorbital constriction; squamosals broader between auditory meatuses; pterygoids broader, the interpterygoid space opening more widely posteriorly; audi- tory bullae less angular, more rounded and inflated; dentition about the same. Compared with O. g. grandis the skull is smaller, less angular; profile straighter, without the marked depression near the fronto-parietal suture and lacking the anterior frontal inflation of grandis; rostrum less elongated; lambdoid crest more evenly curved, less sinuous, less concave forward at median line, as viewed from above; squamosal shelves broader between auditory meatuses; jugal more expanded anteriorly, inserted farther forward in maxilla; basioccipital broader; pterygoids broad and shaped much as in grandis; auditory bullae more inflated anteriorly, bulging downward more nearly to lower plane of basioccipital; dentition about the same. Smaller, less elongated than that of O. g. nelsoni; profile straighter without anterior frontal swelling; ascending branches of premaxillae much narrower; nasals less decurved anteriorly, much broader, less tapering, the sides parallel near posterior ends; squamosals broader between auditory meatuses; basioccipital broader; auditory bullae more rounded and in- flated, less angular; dentition about the same. Measurements.—Type: Total length, 366 mm.; tail vertebrae, 119; hind foot, 49. Skull (type): Condylobasal length, 66; zygomatic breadth (anteriorly), 37.6; greatest breadth across squamosals, 39.1; squamosal constriction between auditory meatuses, 28.5; interorbital constriction, 14.2, length of nasals, 25.4; alveolar length of upper molariform toothrow, 14.2. Remarks.—Orthogeomys grandis annexus is based on a single specimen which shows close relationship to the neighboring forms already described, but exhibits cranial characters beyond the range of individual variation usual in the group. It apparently represents a subspecies that may have an extensive range along the valley of the Chiapas River. Sigmodon guerrerensis, sp. nov. GUERRERO COTTON RAT. Type.—From Omilteme, Guerrero, Mexico (altitude 8,000 feet). No. 126936, @ adult, skin and skull, U. S. National Museum (Biological Nelson and Goldman—Rodents from Southern Mexico. 197 Survey collection), collected by Nelson and Goldman, May 21, 1903. Original number 16467. Distribution.—Known only from the type locality in the high mountains of central Guerrero. General characters.—A large rich-colored species of the Sigmodon fulvi- venter group. Resembling S. allenz of Jalisco, but larger and color darker, more tawny; skull differing in detail. Similar to S. vulcani of the Volcan de Fuego, but color richer, much more tawny instead of ochraceous. Not very unlike S. alticola of the high mountains of central Oaxaca in color, but upper parts more uniformly tawny (dorsum distinctly ‘lined’ with buffy hairs in alticola), and ears blacker; cranial characters very distinctive. Color.—Type: Upper parts light tawny, richest on rump, but purest on cheeks, shoulders and flanks, the top of head and back mixed or lined with black; under parts overlaid with cinnamon buff, becoming abruptly tawny on a narrow area across base of tail; ears blackish; outer sides of forearms and thighs like flanks; fore feet grayish buffy; hind feet dull ochraceous buffy over tarsus, becoming grayish on toes; tail dark brown above, lighter brown below. In an adult topotype the under parts are dull white instead of cinnamon buff as in the type. Skull.—About like that of S. vulcani. Very similar to that of S. allenz, but larger, more angular, with relatively heavier molars; supraorbital and temporal ridges more strongly developed; interparietal large, the anterior border convex or nearly straight and upper incisors heavy and recurved as in allent. Contrasting strongly with S. alticola as follows: Braincase relatively more elongated; rostrum and nasals decidedly broader; inter- parietal much longer (antero-posteriorly). with a prominent posterior angle; supraoccipital region rising nearly perpendicularly (not sloping forward at expense of interparietal as in alticola); dentition heavier. Measurements.—Type: Total length, 278 mm.; tail vertebrae, 128; hind foot, 32. An adult female topotype: 293; 180; 33. Skull (type): Greatest length, 34; condylobasal length, 32; zygomatic breadth, 18.9; interorbital breadth, 5.6; nasals, 13.2; width of braincase (immediately in front of descending process of supraoccipital), 13.3; width of rostrum (maxillae at antorbital notch), 6.1; interparietal (at median line), 4.2; maxillary toothrow (alveoli), 6.3. Remarks.—Sigmodon guerrerensis is closely allied to S. allent and S. vulcani, but the characters pointed out are quite distinctive. It occurs in a more humid area and may be isolated by the broad arid valley of the Balsas River. While a member of the S. fulviventer group, as distinguished from the more widely dispersed S. hispidus group, it requires no close comparison with the much paler species fulviventer of the interior plateau region of Zacatecas and Durango. Specimens examined.—Two, from the type locality. Sigmodon planifrons, sp. nov. OAXACA COTTON RAT. Type.—¥rom Juquila, southwestern Oaxaca, Mexico (altitude 5,000 feet). No. 71918, 9 adult, skin and skull, U. S. National Museum (Bio- 198 Proceedings of the Biological Society of Washington. logical Survey collection), collected by Nelson and Goldman, February 28, 1895. Original number 7569. Distribution.—Known only from the type locality in the mountains of southwestern Oaxaca. General characters.—Size smallest of the Sigmodon fulviventer group; skull small and delicate in structure. Apparently allied to Sigmodon alti- cola of the high mountains of central Oaxaca, but general color paler, the ears clothed with finely mixed black and buffy banded hairs like body (contrasting with finely grizzled ears of alticola), and cranial characters distinctive. Closely resembling S. alleni in color, but cranial characters, especially the slenderer, more depressed rostrum and less recurved incisors quite different. Color.—Type: Upper parts in general between ochraceous buff and ochraceous tawny (Ridgway, 1912), mixed with black, the dark hairs most numerous on top of head and back, thinning out along sides; rump suffused with light tawny; under parts overlaid with dull white, the under color dark plumbeous; ears about like back; feet buffy grayish; tail dark brown above, lighter brown below. Skull.—Cranium small, relatively low and weakly developed. Somewhat like that of altzcola, but smaller and flatter; zygomatic plate broader antero- posteriorly, as viewed from the side; auditory bullae much smaller; rostrum slender and upper incisors with slight recurvature as in alticola. Similar in general to that of alleni, but smaller, flatter, less angular, the basicranial region more smoothly rounded; rostrum slenderer, shallower, more de- pressed anteriorly; auditory bullae small as in alleni; upper incisors lighter, less recurved. Measurements.—Type: Total length, 207; tail vertebrae, 88; hind foot, 29. Skull (adult 2 topotype): Greatest length, 29.5; condylobasal length, 27.9; zygomatic breadth, 17.3; interorbital breadth, 4.7; nasals, 11.8; width of braincase (immediately in front of descending process of supra- occipital), 12.4; width of rostrum (maxillae at antorbital notch), 3.7; interparietal (at median line), 1.8; maxillary toothrow (alveoli), 5.9. Remarks.—This form is based upon a skin and two skulls from the type locality. The skin closely resembles S. allenz, but the skulls suggest rela- tionship to the nearer geographic neighbor S. alticola. It differs, however, from both in characters that seem to warrant specific recognition. No close comparison with the much larger, higher mountain species, S. guerrerensis is required. py too: ALS Vol. 46, pp. 199-200 st PROCEEDINGS Gs OF THE BIOLOGICAL SOCIETY OF waning Are \ oe = ee renee oe er rene THE CUBAN RACE OF THE SNAIL KITE, ROSTRHAMUS SOCIABILIS (VIEILLOT). BY HERBERT FRIEDMANN.! In a paper in the present volume (p. 193) Nelson and Goldman describe a new subspecies of this hawk from Vera Cruz, charac- terized by its large size. Study of specimens from the entire range of the species reveals still another hitherto unrecognized form—the bird of Cuba and the Isle of Pines. This may be known as Rostrhamus sociabilis levis, subsp. nov. Type.—U. S. Nat. Mus. 29578, immature male, collected in Cuba (no definite locality given) by Charles Wright. Subspecific characters.—Wing length asin R. s. plumbeus but bill size as in R. s. sociabilts. Measurements of type.—Wing 351, tail 189.5, tarsus 56, culmen from cere 25.5, culmen with cere 32 mm. Remarks.—Four other Cuban specimens present. the following dimen- sions: wing 350-371 (859), culmen from cere 25-26 (25.2); culmen with cere 32.5-35.5 (33.7 mm.). For comparative purposes the characters of the nominate race and the Florida form plumbeus may be stated briefly. The typical subspecies is a short-winged (325-341, average 331.2 mm.) and large-billed race (culmen from cere 24-26 (25 mm.); culmen including cere 32.2 mm.). The form plumbeus is a long-winged (340-368; average 356.7 mm.) and small-billed race (culmen from cere 22-25 (23.3); culmen including cere 29-32.5 (30.4 mm.)). The nominate subspecies ranges from Uruguay and the northern half of Argentina north to eastern Panama, intergrading in Costa Rica, Nicaragua, and Honduras with the very large Mexican-Guatemalan form. R. s. plumbeus is found only in peninsular Florida. Range.—R. s. levis occurs in Cuba and the Isle of Pines. 1Published by permission of the Secretary of the Smithsonian Institution. 43—Proc. Biou.

BY LOUIS B. BISHOP. In the description of unrecognized subspecies now-a-days one expects not honor, rather obloquy and contumely. That this should be so is easy to understand, as the great majority of those interested in birds study them from some other stand- point, and are not interested, but rather repelled, by what to them seems an overdrawn nicety of discrimination. That forms whose differences are only average, and of which many specimens can not be properly allocated without referring to the locality given on the label, do not deserve subspecific recognition I cordially agree; but when in studying a series of specimens one finds a number from a given locality which he can not call by the name of any at present accepted race with- out doing injustice to his sense of the truth, he must group these differences under a new name, so that those studying other aspects of avian life may be sure which bird it is of which they are writing. This is my apology for the two races described below. Hylocichla guttata dwighti, subsp. nov.! DWIGHT’S HERMIT THRUSH. Type.—Male adult; no. 43677, collection of Louis B. Bishop; Lion Creek, Priest Lake, Idaho, June 23, 1929; elevation 5500 feet; no. 3165 of Charles F. Hedges, collector. Subspecific characters.—Similar to Hylocichla guttata audubont of the southern Rocky Mountains, but much smaller; approaching H.g. nana and guttata in size, but much grayer. Two breeding males from Priest Lake are between hair brown and grayish olive (of Ridgway) above; three young females collected at Priest Lake in September and October are from light brownish olive to buffy olive. 1Named in memory of Dr. Jonathan Dwight. 44—Proc. Bio. Soc. WasH., Vou. 46, 1933. (201) 202 Proceedings of the Biological Society of Washington. Measurements.—Adult males (2 from Priest Lake): wing, 92.5-94 mm. (average 93.2); tail, 71.3-74 (72.6); exposed culmen, 13.5-13.8 (13.7); tarsus, 27.4-28.4 (27.9). Immature females (three from Priest Lake): 86-89.8 (87.3); tail, 66.5-71 (68.1); exposed culmen, 12-13 (12.3); tarsus, 28.3-30 (29.1). Range.—Northern Idaho in summer, passing south through Arizona in fall and southwestern Idaho in spring. Remarks.—During the years 1926-31, Mr. Charles F. Hedges collected for me a number of birds in Idaho, chiefly at Coeur d’ Alene, Priest Lake, in the northern part of the state, and at Payette in the southwestern portion. When I received the two male Hermit Thrushes described above they were so different from any race I knew that I asked him to get more; but the bird was evidently rare, or he was not at the center of abundance, as the three young females from Coolin, Priest Lake, mentioned above, were all he was able to take. A female (?) Hermit Thrush, however, which he collected at Payette on May 19, 1930, is identical in color with the June males from Priest Lake, and has a wing of 92 mm.; tail, 73; exposed culmen, 13.7; tarsus, 29.8. An adult male Hermit Thrush collected by Mr. H. H. Kimball at Cooley, Arizona, Nov. 10, 1920, and a young female on Nov. 2 (35135,7) agree in color with the fall birds from Priest Lake, and are about the same size—wing, 89.5 and 86.5; tail, 67.5, 68; exposed culmen, 14, 14.3; tarsus, 28.5, 29—and I refer them to dwighiz. The type of H. g. auduboni,—a male, collected at Fort Bridger, Utah (now Wyoming), May 28, 1858, now no. 10886, United States National Museum,—Dr. Oberholser has kindly measured for me and finds the wing 106 mm.; tail, 80; exposed culmen, 15; tarsus, 32.5. Seven male Hermit Thrushes from Reserve, New Mexico, and Paradise and the Chiricahua Mountains, Arizona, collected by H. H. Kimball, average,—wing 103.4; tail 81; exposed culmen, 14.8; tarsus, 30.3, and indicate the name auduboni properly belongs to the bird of the southern Rockies, and the northern Idaho bird is new. In Idaho the summer range of dwighti is apparently limited to the far northern portion, as the only Hermit Thrushes Mr. Hedges collected at Coeur d’ Alene—a male on Oct. 4, and a female on Oct. 8, 1926—are refer- able to H. g. guitata. While three breeding birds he obtained at 4500-4700 feet at Tamarack, Washington Co., in the southwestern part of Idaho,—one male and two females,—I refer to H. g. polionota, as in color above they resemble closely H. ustulata swainsoni, and measure—male, wing 105; tail, 81; exposed culmen, 15; tarsus, 32; females, wing, 92.5-95.5; tail, 75-73; exposed culmen, 15—14.3; tarsus, 29-30. To this race also I refer two males collected by Mr. Kimball at Saliz Canyon, Reserve, New Mexico, on Sept. 27 and Oct. 5, 1927, and a female on Oct. 9, 1928 (41639-40, 43176), because of their close resemblance in color to the Tamarack birds, though they are slightly smaller.

Bishop; Cutler, Dade Co., Florida, February 5, 1932; L. B. Bishop, collector. Subspecific characters.—Resembles most closely L. l. excubitorides and sonoriensis in color, but is even clearer bluish (not brownish) gray above— about light neutral gray of Ridgway, and purer white on breast and lower parts, not stained with brown; wing and tail shorter, bill shorter and less hooked than sonoriensis. Resembles ludovicianus, but is much paler above (not the dark gull gray of the latter), and pure white, not sooty white, below; wing and tail slightly shorter and bill longer and heavier. Measurements of five males and five females, all from Dade county, Florida—Males: wing 93-98 mm. (average 95.4); tail, 94.5-99.5 (97.9); exposed culmen, 16.3-17 (16.9); depth of bill at base, 8.8-9.7 (9.3). Females: wing, 89.5—94 (91.3); tail, 89-94.3 (92.5); exposed culmen, 15.4-16.8 (16.1); depth of bill at base, 9mm. Nineteen (twelve males and seven females) L. 1. ludovicianus from Robeson Co., North Carolina; Mt. Pleasant and St. Helen’s Island, South Carolina; Roswell, Georgia; Stewartsville, Ala- bama; Amelia Island, Enterprise, Orlando, Palatka, Lundy, Buffalo Bluffs, ‘and Putnam Co., Florida; males: wing, 96.3-103.3 (98.2); tail, 91.7-108 (99.2); exposed culmen, 14.8-17.5 (16.3); depth of bill at base, 8.2-10 (9.1); females: wing, 93-100 (95.4); tail, 93-103 (98.5); exposed culmen, 14.5-17.6 (15.5); depth of bill at base, 8-9.5 (8.8). Range.—Dade County, Florida, including Key Largo. A common, ‘permanent resident. Remarks.—As is well known, southeastern Florida is the only portion of the United States in the Humid Tropical Zone, and avian forms from the West Indies find their northern limit there. Remembering this I collected one or two of most of the resident species, including four shrikes, all from south of Miami, while spending the winter of 1931-2 at Coconut Grove. More it seemed inadvisable to take, as the Assistant Game Commissioner was very averse to scientific collecting But those four shrikes, on comparison with others from farther north in the state, showed themselves at once so distinct that I asked Mr. Semple to aid me, and through his kindness I obtained four more, including one from Key Largo, where shrikes are very rare; Mr. Adriaan van Rossem lent me two from the Donald Dickey collection in the California Institute of Technology collected by Mr. H. H. Bailey south of Miami. To these gentlemen my thanks are due as these specimens verified what mine indicated. Forty shrikes from northern Florida and eight from North and South Carolina, Georgia and Alabama, which I examined in this connection, show upper parts of neutral gray to dark gull gray with no approach to the pale to light neutral gray of miamensis. The scapulars also are more broadly 204 Proceedings of the Biological Society of Washington. white, in the latter, and the upper tail-coverts often as white as in excu- bitorides and sonoriensis. This study led me to an examination of some 90 shrikes from the West, and these birds agreed with Dr. Miller’s dictum that birds from the coast region of California north to Payette, Idaho, and northeast to Deer Lodge, Montana, and Salt Lake City, Utah, are darker—gambeli, and that birds from Imperial and part of Riverside counties, California, southern Arizona and New Mexico, and south into Sonora, Mexico, are slightly paler, with longer tails and slightly longer bills with a more pronounced hook than gambeli, and also than the birds of the region west of the Mississippi Valley not included in the ranges of the other two. I believe his sonoriensis is an easily recognizable race. But I fail utterly to find any satisfactory charac- ters separating his nevadensis from the other birds of that region, and think excubitorides must be applied to all the shrikes from Manitoba, North Dakota, Saskatchewan, western Kansas, western Texas, Colorado, to Bakersfield in the southern San Joaquin Valley and Victorville on the Mojave Desert of California, occasionally wandering south in winter to Witch Creek, San Diego Co.; though I heartily agree that birds from the eastern border of this range blend into migrans, as the latter does into ludovicianus. This brings me to another point on which Dr. Miller and I differ, that is our definition of intergradation. Some years ago in The Condor I stated execubitorides (then including sonoriensis) breeding in close connection with gambeli in southeastern San Bernardino County in the Mojave Desert does not intergrade with it, and that the same was true at San Gorgonia Pass, while Dr. Miller, in his description of sonoriensis and nevadensis in The Condor, XXX, p. 155 and 6, and in his Systematic Revision and Natural History of American Shrikes (Lanius), p. 69, says they do. Inter- gradation as I understand it is exemplified in a meeting and blending such as occurs where excubitorides and migrans and the latter and ludovicianus meet; but this condition is not what obtains where gambelz and sonoriensis breed only a few miles apart at San Gorgonio Pass, or where gambeli and excubitorides breed side by side in the Mojave Desert. Fourteen shrikes which I have collected in the Coachella and Imperial Valleys are all sonorien- sis while those on the western side and even through San Gorgonio Pass to Cabazon and Fingal are easily recognizable as gambeli. An adult and soon-to-lay female (42304) collected at Coyote Wells on the western side of the Imperial Valley on February 6, 1928, is particularly instructive in this connection; it combines the long tail (108 mm.) of sonoriensis with the darker colors and shorter bill of gambeli—a condition indicative of hybrid- ism, not intergradation. An adult male on the other hand (42505) col- lected by Mr. George G. Cantwell at Palms, Los Angeles County, on Sept. 12, 1928, has the shorter bill of excwbitorides but the longer tail (108 mm.) and slightly paler upper parts of sonoriensis. From near Victorville on the Mojave Desert I collected ten shrikes, five males and five females, almost all in March or April. Of these birds two males and two females seem to me typical excubitorides, two males and two females equally typical of gambeli, and the remaining male and female intermediate. As I under- Bishop—Unrecognized Races of North American Birds. 205 stand Mendel’s law this is the condition and ratio to be expected where two species hybridize. Therefore, since I find races, characterized by only such slight differences that I must believe they were developed in a not very remote past, when meeting on the same breeding ground still retain these same small peculiarities, I can only conclude that in spite of appearances, they have become so somatically and genetically distinct that they hy- bridize as species do, not merely intergrade. a We GO OF wd Vol. 46, pp. 207-212 I October 26, 1933 | PROCEEDINGS OF THE LM it BIOLOGICAL SOCIETY OF WASHINGTON THE LONG-TAILED MEADOW-MOUSE OF SOUTHEASTERN ALASKA. BY HARRY S. SWARTH, California Academy of Sciences. The long-tailed meadow-mouse of the Sitkan district, south- eastern Alaska, has commonly gone under the name of Microtus macrurus Merriam (Proc. Acad. Nat. Sci. Phila., 1898, p. 353), described from Lake Cushman, Olympic Mountains, Washing- ton. From the first, Alaskan specimens so-called were recog- nized as being slightly different, but nevertheless it has been assumed that Microtus macrurus inhabited the coastal strip from Puget Sound north to Yakutat Bay. In 1919 Mr. Joseph Dixon and myself collected a series of specimens along the valley of the lower Stikine River whereby I was able to demonstrate intergradation between the gray Muicrotus mordax of interior British Columbia and the brown ‘‘macrurus”’ of the Alaskan coast, and I accordingly labelled the latter Microtus mordax macrurus (Univ. Calif. Publ. Zool., vol. 24, 1922, p. 175). At about the same time A. B. Howell had independently arrived at essentially similar conclusions (Journal of Mammalogy, vol. 4, 1923, pp. 33-37), evidently without having seen my own paper. This was all right so far as it went, but my findings had been based entirely on Alaskan material and at the time I did not appreciate the resulting corollaries affecting typical macrurus of the Olympic Mountains. For some years past I have devoted considerable thought, with several seasons of field work, to study of the relationships of the closely adjacent faunas of northern British Columbia and southeastern Alaska. The accumulating evidence goes to show that much of the mammal fauna of the Sitkan district is directly derived from the hinterland east of the Coast 45—Proc. Bion. Soc. Wass., Vou. 46, 1933. (207) 208 Proceedings of the Biological Society of Washington. Ranges; that it does not form part of a homogeneous population ranging unchanged the length of the humid coast belt. There are exceptions, of which the Black-tailed Deer is an example, but I have no hesitation in making this rather positive statement of affinities and derivation of most of the Sitkan mammals. With birds it is different (and with plants also, I believe), for much of the avifauna had its origin on the southern coast, but even in the birds there is a certain proportion that provides interesting examples of derivation from the interior. In this connection it is well to consider the other species of Microtus of the Sitkan district. Microtus sitkensis, on Baranof and Chichagof islands, is of boreal origin (of the operarius group), reaching these northern islands along with certain other more northern forms of life that, with it, do not extend south of Christian Sound and Frederick Sound. The Microtus pennsylvanicus stock is widespread in eastern North America, it extends west to the Rocky Mountains in the United States, crosses that range near the Canadian boundary, and (in the race drummondi) is abundant as far as the Coast Range in northern British Columbia, a mode of distribution that is repeated over and over again among mammals and birds of the last mentioned region. This meadow-mouse has even found its way through the Coast Range in at least two places, following the valleys of the Taku and Stikine rivers, but although known to occur at the mouths of those streams, it has not spread along the adjacent Alaskan coast. Mucrotus pennsylvanicus admiraltiae, a slightly differentiated offshoot, is restricted to Admiralty Island. The position of this island directly opposite the mouth of the Taku River, and the nebulous character of the differences between admiraltiae and drummondi, are sufficiently suggestive of the recent derivation and course of travel of the island mouse. Of most of the small mammals of the Sitkan district there is similar evidence of northern or eastern relationships. Such an exceptional mode of distribution as has been ascribed to macrurus, comprising the narrow coastal strip from Puget Sound north into Alaska, should be carefully scrutinized. Furthermore, the demonstrated intergradation between mordazx of inland British Columbia and ‘‘macrurus” of the Sitkan district, via the Stikine Valley, implying derivation of the Alaskan stock from the neighboring interior, leaves the more widely different typical macrurus of the Olympic Mountains unexplained in relationship to the northern forms. Derivation of the Alaskan stock of this species from the interior is in- ferred from satisfactory reasons. Intergradation of the sort described is commonly accepted as the test of subspecific difference. It implies, I believe, impending separation of parts of a previously homogeneous form (witness the common definition of a subspecies as an incipient species); and, on the other hand, to the best of my belief does not occur when two related forms (even some that are designated as subspecies) approach and meet subsequent to their differentiation in other regions. The last men- tioned condition is illustrated in several bird groups in this northwestern country. For examples, the Russet-backed Thrush (Hylocichla ustulata ustulata) and Olive-back Thrush (H. w. swainsoni) meet in the Stikine Swarth—Long-Tailed Meadow-M ouse of S. HZ. Alaska. 209 Valley without blending; the Red-shafted Flicker (Colaptes cafer) and Yellow-shafted Flicker (Colaptes auratus) meet in the Skeena Valley, to result in parti-colored individuals that are commonly regarded not as intermediates but as hybrids. It is safe to say that the Sitkan district was colonized by animal and plant life at a more recent date than the region east of the Coast Ranges or than the coastal region to the southward, and in nearly every case the mammal and bird species of the Sitkan district betray in their physical characteristics or in their mode of local distribution, often in both, the source whence they came. In the case of the Microtus under discussion, if it really were genetically close to macrurus of the Olympic Mountains it must have invaded the Sitkan district from the southward, have met with mordax of the upper Stikine Valley at a much later period, and have combined with that species to have produced the gradual blend of characters that is evident over so wide an area. These are the corollaries above referred to that I did not grasp at the time when the subspecific relationship of mordax and Alaskan ““macrurus”’ became clear to me. Of late, realization of the improbability of this situation impelled comparison of specimens from the several regions involved. True macrurus is a rare animal in collections, and in all my previous work on northern mammals I had contented myself with the published state- ments pertaining to that form, which was no longer satisfactory. In aid of the present study I have been able to borrow from the United States Biological Survey three topotypes of Microtus macrurus, and from Field Museum, Chicago, eight more specimens from the Olympic Mountains. Of these eleven specimens, four are fully adult. The Biological Survey series includes also six specimens from Rivers Inlet and three from Lund, localities on the mainland coast of southern British Columbia. I have also had available the large series of Microtus of the Sitkan district, Alaska (mostly collected by myself), that is in the Museum of Vertebrate Zoology, University of California. Comparisons of the several series (and with special reference to three fully adult macrurus in the Field Museum collection) is corroborative of | the suspicion that the Alaskan form should not be regarded as Microtus macrurus. 1 propose to call it Microtus mordax littoralis, new subspecies. Type.—Male adult, skin and skull; no. 8642 University of California Museum of Vertebrate Zoology; Shakan, Prince of Wales Island, Alaska; May 14, 1909; collected by H. S. Swarth; original number 7463. Geographic range.—Mainland coast and most of the islands of south- eastern Alaska. On the coast from Yakutat south at least to Bradfield Canal. On most of the islands of the Alexander Archipelago that lie east of Chatham Strait and to the southward. Diagnosis.—A long-tailed meadow-mouse of the Microtus mordax aggre- gation. From M. mordax mordax of the adjacent interior of British Columbia, littoralis differs in being reddish-brown instead of grayish in general aspect, and in having a somewhat longer tail. Intergradation 210 Proceedings of the Biological Society of Washington. between mordax and littoralis has been traced along the valley of the Stikine (see Swarth, Univ. Calif. Publ. Zool., vol. 24, 1922, pp. 175-178). Measurements.—Type: Length, 189 mm.; tail vertebrae, 72; hind foot 22. Ten adults, Prince of Wales Island, Alaska (average, minimum and maxi- mum): Length, 189.3 mm. (172.0—207.0); tail vertebrae, 73.3 (63.0—-80.0); hind foot, 21.1 (20.0-22.0). Microtus macrurus: ‘‘ Average of five specimens from three localities in the Olympic Mountains: 204; 80; 24.3” (Bailey, N. Am. Fauna, 17, 1900, p. 51). Measurements taken by different individuals, especially under the con- ditions ordinarily affecting the field collector, are not a satisfactory basis for fine comparisons, but, making all necessary allowances, adult examples of Microtus macrurus are clearly larger than any form of mordaz that I have seen (except Microtus coronarius). Macrurus is darker colored, less reddish above; and the belly is darker colored than in littoralis and not so sharply contrasted with the sides. In macrurus the tail is longer. In most specimens it is scantily haired, almost the same color above and below; only in the younger examples does it approach the sharply bicolored effect that is the rule in Jzttoralis. The skull of adult macrurus is appreciably larger than that of littoralis, reflecting the general size differences that are apparent in the externals of the two. Despite the greater size, the skull of macrurus presents a weaker appearance, being built on more slender lines, with the zygomata less wide set and angular than in /ittoralis, the nasal region rather more elongated. I can not now regard macrurus as a subspecies of Microtus mordaz, the available specimens being few in number and otherwise unsatisfactory as a basis for such a decision. The several skins at hand from the British Columbia mainland at Lund and Rivers Inlet I am content for the present to consider the same as macrurus of the Olympic Peninsula, but it will require much more material and from localities not now represented in collections before satisfactory conclusions can be reached regarding rela- tionships and distribution of the long-tailed forms of Microtus of the Puget Sound region. Elliot (Field Colum. Mus., Zool. Ser. I, 1899; p. 257) remarks of macrurus: ‘This large species was only procured by me on the banks of the Elwah and was not seen on the high mountains, so I concluded it was an inhabitant of the lowlands, possibly, indeed, also a littoral form.” The Lund and Rivers Inlet occurrences are corroborative of this view. I believe that there is close relationship between Microtus macrurus and M. tetramerus of Vancouver Island, which is not surprising, considering the geographical situation. The Vancouver Island mouse is smaller and slightly more reddish, but it has the same sort of tail as macrurus, though a shorter one, and the same character of skull. The assumption of continuous distribution of macrurus along the coast north from Puget Sound to Alaska was never based upon specimens. Be- tween those points lie some hundreds of miles of shore line almost unknown zoologically. Considerable field work has been done on Vancouver Island and on the Queen Charlotte Islands, but otherwise the entire coast of British Columbia, mainland and islands, awaits even the most cursory inspection of its fauna. Neither are there available any Microtus from the Swarth—Long-Tailed Meadow-Mouse of S. E. Alaska. 211 southernmost 125 miles of the adjoining Alaskan mainland. I, myself, trapped at several points in the last mentioned territory without result, though I got specimens on some of the neighboring islands. Howell (loc. cit.) remarks: “‘Specimens of macrurus from southern Alaska are puzzling. Series from almost every locality available show slight, consistent differences, but in no case are these sufficient for subspecific rank, and they must all be included under the one name.”’ This condition, as well as peculiarities of distribution, might be explained under the theory I am here advancing, namely, that these mice have found their way to the Alaskan coast from the adjacent interior and by several routes, the Alaskan population therefore consisting of colonies derived from slightly different sources and perhaps remaining separated up to the present time. This is just the situation that we can see exists in the case of the forms of Microtus pennsylvanicus in the same region. In southeastern Alaska there is a peculiar development in the existence of Microtus coronarius, a giant form of the same stock as M. mordaz lit- toralis, and one that has apparently originated in its present environment. It has been taken on Coronation, Warren and Forrester islands, a discon- nected habitat that is as yet inexplicable. There are other islands along the western edge of the Alexander Archipelago on which no zoological collecting has been done, and such work, when it comes, may bring a better understanding of this variant. I wish to express appreciation to the officials of the United States Biological Survey, of Field Museum, Chicago, and of the Museum of Vertebrate Zoology, University of California, for the privilege of bringing together the material upon which these comments are based. , V¥lo fom! Vol. 46, pp. 213-216 November 20, 1933 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WAG THREE NEW UROTHRIPIDA FROM PANAMA. BY J. DOUGLAS HOOD, University of Rochester. The types of the new species described below are in the author’s collection. Trachythrips deleoni, sp. nov. Female.—Length about 1.1 mm. Color straw-yellow, with head, pro- thorax, and mesothorax uniform dark brown, extreme sides of metathorax and of first and ninth abdominal segments, as well as tip of tube, narrowly brown; remaining abdominal segments brown in lateral fourths or fifths, excepting for a paler area behind the middle of the blotches on segments 2 and 3 and a pale spot at the base of each major seta at the distal angles of segments 4-7; median portions of segments 3-8 with a pale brown cloud; legs with fore femora white, fore and hind tibiz brown (darkest on outer surface) excepting for the pale ends; middle and hind femora and middle tibia narrowly dark brown along outer surface; all tarsi with cups brown; antenne white in segments 1 and 2, shading through yellow in segment 3 and brownish yellow in 4 to light brown in 5; bright red subhypodermal pigmentation in head, prothorax, and along sides of abdomen. Head scarcely 1.2 times as long as greatest width, pointed rather than truncate or emarginate in front, not produced beyond eyes to form a bilobed process, with the shallow median dorsal furrow crossed by anastomosing lines which form distinct reticles posterior to the eyes, this furrow devoid of tubercles. Eyes as in the genotype but with the two caudo-mesad facets usually separated by a single setigerous tubercle. Male.—Smaller than female (length about 0.9 mm.), but otherwise similar. Described from 46 mounted specimens, of which 11 are males, all taken at Porto Bello, Panama, July 9 and 10, 1933, from dead leaves, branches, and standing herbaceous vegetation. The italicized portions of the above description distinguish it readily from 7’. watsoni Hood, the genotype, and the two new species described below. It lacks the pronotal pale spot and the cephalic prolongation found in T. frontalis n. sp.; the white femora and the eye structure separate it 46—Proc. Brox. Soc. Wasu., Vou. 46, 1933. (213) 214 Proceedings of the Biological Society of Washington. readily from 7’. watsoni; while the dark tibiz, less tuberculate head, and the presence usually of a single setigerous tubercle between the two inner posterior facets of the eyes serve to distinguish it from T. albipes n. sp. It is named after Sefior Don Juan E. de Leon, Governor of the District of Portobelo, Panama, to whom I am indebted for many courtesies. Trachythrips albipes, sp. nov. Female.—Length about 1.1 mm. Color straw-yellow, with head, pro- thorax, and mesothorax uniform dark brown; extreme sides of metathorax and of ninth abdominal segment, as well as tip of tube, narrowly dark brown; remaining abdominal segments brown in lateral fourths, excepting for a paler area behind the middle of the blotches on segments 2 and 3 and a pale spot at the base of each major seta at the distal angles of segments 4-7; median portions of segments 3-9, with a light brown cloud at base, at least; legs of fore pair clear white, save only for the dark, blackish brown coxe and the paler brown tarsal cwps; middle and hind femora and middle tibize narrowly dark brown along outer surface; hind tibie brown (darkest on outer surface) excepting for the pale ends; antenne nearly white in segments 1 and 2, shading through yellow in segment 3 and brownish yellow in 4 to light brown in 5; bright red subhypodermal pigmentation in head, prothorax, and along sides of abdomen. Head somewhat more than 1.2 times as long as greatest width, truncate rather than pointed or emarginate in front, slightly produced beyond eyes but scarcely to form a bilobed process, with the median furrow very shallow, conj ied to space between the eyes and crossed by only a few anastomosing tines which scarcely form distinct reticles posterior to the eyes, the median region of head minutely tuberculate excepting for a brief space between the eyes. HWyes as inthe genotype, but with the two caudo-mesad facets separated by two setigerous tubercles. Male.—Smaller than female (length about 0.9 mm.), but otherwise similar. Described from many mounted specimens, of which several are males, all taken on Barro Colorado Island, Canal Zone, Panama, July 29 and August 14, 1933, from dead branches. Readily known from the other species of the genus by the italicized portions of the above description. The white fore femora and tibie are quite distinctive, separating it at once from its congeners. It takes a natural position between the species described above as T’. deleoni and T. frontalis described below. Trachythrips frontalis, sp. nov. Female.—Length about 1.1 mm. Color straw-yellow, with head dark brown; prothorax dark brown excepting for a white crescent-shaped blotch involving the entire front margin of pronotum and the anterior third of its median length; mesothorax, adjoining portions and sides of metathorax, and sides of abdominal segments 1 and 9, as well as tip of tube, dark brown; remaining abdominal segments brown in lateral fourths, excepting for a Hood—Three New Urothripide from Panama. 215 paler area behind the middle of the blotches on segments 2 and 3 and a pale spot at the base of each major seta at the distal angles of segments 4-7; median portions of segments 3-9 with a light brown cloud at base, at least; legs of fore pair white, with dark brown coxe, brown tarsal cups, and a lighter brown cloud occupying the second and third fifths of the tibie; middle and hind femora and tibiz dark brown along outer surface, the tibie frequently crossed by a light brown cloud, their tarsi with brown cups; antennez pale yellow, darkening distally, with segment 4 brownish yellow and segment 5 yellowish brown; bright red subhypodermal pigmentation in head, prothorax (more abundant usually in the white pronotal Bloch); and sina sides of abdomen. Head about 1.25 times as long as greatest width, decidedly produced beyond eyes to form a broadened process which is usually distinctly bilobed or emarginate (though occasionally only truncate); median dorsal furrow very shallow, crossed by many anastomosing lines which form distinct reticles posterior to the eyes, this furrow devoid of tubercles though margined with about ten setigerous ones on either side. Eyes as in the genotype, but with the two caudo-mesad facets separated by two setigerous tubercles. Male.—Smaller than female (length about 0.9 mm.), but otherwise very similar; cephalic prolongation less distinct, broadly rounded rather than bilobed in front. Described from a large number of mounted specimens, of which several are males, taken on Barro Colorado Island, and at Frijoles, both in the Canal Zone, and Chorrera, Panam4; July 6—August 13, 1933. The frontal projection and pronotal pale spot are possessed by no other species of the genus. It is closer to 7’. albipes, described above, than to its other congeners.
