19301 New Neuropteroid Insects
SOME NEW NEOTROPICAL NEUROPTEROID
INSECTS
BY NATHAN BANKS
Museum of Comparative Zoology, Cambridge, Mass. The following new species from the collection of the Mu- seum of Comparative Zoology are mostly from Cuba and chiefly obtained in the past few years.
Psocidse
Compsocus gen. nov.
Belongs to the Amphientominse. Head moderately broad, bent down, clypeus fairly large, ocelli present, legs rather short, hind pair longer, tarsi of three joints, femora rather swollen, on hind tibia only a few spines on lower apical half. In hind wings the media is forked, and the axillary separate from anal. In fore wings the subcosta is long, curved, and ends in radius, forming a long cell; but one axillary vein, but this plainly forked toward base, axillary and anal end together; radius forked once, media twice; the cubital fork is near to margin and so almost forms an areola postica; surface of wing with many minute, short scales, some stout and rounded at tip, others longer and forked at tip, each kind in separate patches. Compsocus elegans sp, nov.
Figure 4.
Black; antennae very fine and thin; legs black, tarsi pale, hind basitarsus with dark band near middle. Wings black, with three hyaline white spots along hind margin, one at end of anal, one over lower branch of cubitus, and one over

end of upper cubitus and reaching up to radial branch. On the surface of wing about 12 large silvery white spots; about five tending to form a row across near end of stigma, one of which is in end of stigma and extends beyond to next vein, one in the base of radial fork, two behind it, and one in the median fork; about middle of length are two more silvery spots, and before this an interrupted band from costa just beyond subcostal cell, and extending across radius, and two spots nearer to base; hind wings fumose, veins darker. In fore wings the short, rounded scales are in pale areas, the forked scales densely placed to form dark areas. Both wings iridescent.
Length 2.2 mm.
From Barro Colorado Island, Panama, 23 June. A re-
markably beautiful species.
Hemipsocus pretiosus sp. nov.
Figure 5.
Head dull yellowish, unmarked; antennae also, likewise the thorax, abdomen blackish above, femora dark, tibia and tarsi pale; head, thorax and antennae with moderately long, pale hair. Fore wings mostly brown; veins nearly black, the longitudinal veins with white spots, particularly prominent beyond the middle; two larger white spots on posterior margin just beyond the end of the cubital vein; veins with erect hairs arising from black spots; the vein bounding areola postica and the cross-vein above it are hyaline-white ; hind wings grayish hyaline. Wings shorter than in H. roseus, but the venation is very similar, the fork of the median vein, however, reaches back to the cross-vein to areola postica or even onto the cross-vein. Length of fore wing 2.2 mm.
One from Soledad, Cuba, 18 February (Myers) and the other from Royal Palm Park, Florida (Blatchley) .

New Neuropteroid Insects
Ephemeridae
Callibaetis completa sp. nov.
s Body of the usual pale brownish, with many small dark dots, especially on the abdomen, beneath with larger, paired dots, above on abdomen the basal segments show a large dark spot in middle, tending to form a stripe; second joint of antennae mostly dark brown; legs pale, the tarsal joints faintly dark at endings. Wings hyaline, a broad brown stripe along front margin, covering the first three veins, and on base a little more; this brown fills the costal area to base, and also at tip, it contains a number of trans- verse hyaline white marks, mostly over veins, very few of these pale spots in the apical fourth, behind the brown is fairly even. The veins are brown, and cross-veins also; there are a few cross-veins near tip, about eleven in a curved series from middle back to near base, before middle near middle of length are three cross-veins, and toward base three more.
Length fore wing 7.5 mm.
From Soledad, Cuba, 20 June (G. Salt).
Hemerobiidae
Hemerobius cubanus sp. nov.
Head brownish yellow, no distinct marks; antennae similar, but paler toward tips; thorax also similar, with long pale hair above; abdomen darker brown; legs pale, the tibiae (especially of second and third pairs) swollen toward tip, the hind ones with a dark line on the hind edge of the swollen part.
Wings nearly hyaline, or faintly fumose; veins brown and pale in spots, and brown at origins, and from the brown spots are often extensions of brown out on the membrane; the gradates dark brown, and bordered with brown; stigma not distinct; the brown marks are closer and more distinct in the posterior basal part of wing; hind wing with some brown near tip over the cross-veins and also near base over the branches from anal vein. Wings about of shape of H.

groups of two or
three dark dots; the gradates and an oblique streak up from end of anal nearly black, a brown spot at extreme base of wing, and often small dark dots at forking of veins; just beyond the first gradates there is a narrow pale stripe across wings; hind wing with dark before stigma, the basal part of radial sector and some apical dots dark. Costal area as wide as head plus the pronotum; five radial sectors, the fifth forked at first gradates and upper branch forked again before the second gradates. The median forked just before origin of second radial sector, cubital forked before first gradates.
Expanse 13 mm.

190 Psyche [June
Pronotum much broader than long; first tarsal joint about one-half of fifth; spurs about equal to first joint. In the
fore wing seven cross-veins before radial sector, in hind wings four, the first very oblique, about eight branches of the radial sector; in hind wing three or four branches of first anal vein; in fore wing about twelve connections be- tween radial sector and radius before the stigma. In fore wing (and also in hind pair) there is no definite line in cubital area parallel to cubitus as is present in nearly all species; there is the usual curved beginning of such a line, but it soon runs into the center of a series of diamond-shaped cells.
Length fore wing 34 mm., width 7.3 mm.; length hind wing 30 mm., width 6 mm.
From Cuba (Chas. Wright).
Readily separated from the common Cuban M. insertus by larger size, as well as peculiar structure of cubital area. Austroleon garciana sp. nov.
Head pale, a large dark interantennal mark reaching up to vertex, a narrow dark band across above clypeus, last joint of palpi marked with dark, vertex with two conjoined dark spots above, each enclosing a pale spot behind, an- tennse dark, faintly annulate with pale. Pronotum pale, two rounded dark spots in front, two streaks behind and a lateral dark stripe, margin with some long, curved, white bristles; meso- and metanotum much marked with dark, the scutelli with a median dark spot, pleura brown, with several pale spots, legs pale, dotted and spotted with brown, third and fourth tarsal joints almost wholly black, front coxa with several curved white macrochsetse, also a row above on the front femur; spurs equal to two tarsal joints. Abdomen dark, several segments show one or two pale spots or streaks each side above, hair above black on basal part, paler toward tip, venter with white hair. Wings hyaline, veins dark, with pale spots, a rather dis- tinct spot at the rhegma, radial sector in the hind wings almost wholly dark. Wings slender, much more so than in

A. cubitalis Navas; venation generally similar to that species, two or three cross-veins in hind wings before radial sector, three in fore wings, about five branches to radial sector. The hind wing is so slender that the branches of cubitus are nearly simple, only a few forked and no cross- veins between them as in A. cubitalk the marginal hair is shorter than in cubitalis. Fore wing, length 16-18 mm., width 3.5-4 mm. Hind wing, length 15-17 mm., width 2.5-3 mm. Abdomen 16-18 mm. long.
From S. Barbara, 15 March, and N. Gerona, 1 March, Isle of Pines, Cuba, both by C. S. Bruner. Differs from cubitalis Navas not only in smaller size, more slender wing, but also in pronotal marks, cubitalis having a single median mark behind; the spots on vertex also different. Both specimens lack the spots along cubitus seen in cubitalis.
