72 Psyche [March
NEW NATIVE NEUROPTEROID INSECTS
The following few descriptions are based on materials gradually accumulating in the Museum of Comparative Zoology. A generic synopsis of our Capniinae, including two new genera, is based on characters that, I believe, are better than those previously used in this group. ORDER CORRODENTIA
Polypsocus corruptus Hag.
In the South there are two varieties which should be named :
P. corruptus var. pictilis n. var.
Females differing from typical corruptus in having a large pale area in middle of fore wing, similar to that of the nor- mal male of cowuptus, but more distinct; the preapical pale band is as in normal females. In male this middle pale area is more extended so as to meet the pale apical spot beyond the stigma, thus isolating the dark stigma. In none of these specimens is the stigma reddish as is common, but not con- stant, in typical comptm. Size same as typical form. This form was very common in the Smoky Mountains of Tennessee, near Newfound Gap, at about 5000 feet, in Sep- tember. In the valleys the typical form was common. Type M.C.Z. no. 22659.
P. corruptus var. omissus n. var.
The male differs from the typical form in lacking all pale marks in the fore wing, neither the median area nor the triangular area beyond stigma, only the minute pale dot at base of stigma, and at base of areola postica. The two males have slightly shorter wings than usual. From Great Falls, Va., 21 July, and Clarksville, Ga., 10 Aug. Type M.C.Z. no. 22660.

74 Psyche
[March
I. fumosa, herewith described, and a clear winged species in which the radial sector is forked beyond the cross-veins ; all are from the northwestern parts of United States and western Canada.
Isocapnia fumosa sp. nov.
Figure 3
Body black, posterior parts of meso and metanotum polished, legs, antennae, and setae also uniformly black. Both wings fumose, almost black on front part, the cells behind are paler in the middle, veins black. Body with only minute hairs, those on legs not half as long as in I. crinita. Pronotum a little broader than long, scarcely at all narrowed behind.
In fore wings six to nine costal cross-veins, oblique vein arising about its length beyond the subcosta ; all apical veins unforked; in hind wings several (four to five) costal cross- veins, lower branch of medius forked; anal area reaches about two thirds way to tip.
The last dorsal segment of the abdomen projects at a slight angle in the middle. The ventral plate is broad and broadly rounded, each side of its median tip a ridge runs obliquely over the next segment.
Length of fore wing 16 mm.
From Oregon National Forest, Herman, Oregon, 18 April, 1920, and Junction City, Oregon, 7 April, 1919 (both A. C. Burrill). Type M.C.Z. no. 22661.
Nemocapnia gen. nov.
Body and wings slender, radius not bent at origin of radial sector, no oblique cross-vein beyond end of subcosta, rest similar to Arsapnia; in hind wings the anal area reaches only a little beyond middle of wing; setae probably short, the joints beyond the first two three much elongate; in type species apparently but seven joints.
Nemocapnia Carolina sp. nov.
Figures 1, 2, and 6
Body black, antennae and legs slightly paler, all densely

clothed with long hair, especially long on the legs ; fore wings nearly hyaline, slightly gray, veins brown, veins and margin with short hair, membrane with very minute hairs; hind wings similar. Fore wings slender, radius not bent at origin of radial sector, only one or two costal cross-veins and these near tip ; no cross-vein beyond end of subcosta, none of apical veins forked, and all subparallel. Hind wings with subcosta ending before middle of wing, lower branch of medius with a long fork.
Pronotum a little broader than long, sides parallel. Setae with seven joints (possibly have been more), all but the basal two elongate, longer than in related forms. The male has the long median piece (in the only male) projecting behind, but probably normally recurved. Fore wing 6 mm. long.
From Morgantown, N. Car.
(Morrison), mixed in with
specimens returned from a loan as "Leuctra spp.". Type M.C.Z. No. 22662.
ORDER NEUROPTERA
Abachrysa gen. nov.
Body broad and heavy; antennae close together at base, not as long as wings ; pronotum about twice as broad as long ; fore wings with divisory cell much as in Nodita, six cubital cross-veins beyond it ; costal area only moderately broad ; the branches from cubitus to hind margin are in pairs, the two from each cell close together at base, or often united in one stem; the cross-vein from subcosta to radius is nearly as far out as base of divisory cell; the second cubital cell no longer than the first.
In the hind wing there is no trace of the triangle between base of radial sector and the medius, the radial sector, ap- parently, is here united to the upper median vein. Genotype, Chrysopa eureka Bks.
It differs from Chrysopa and many other genera in the broad pronotum, in the short second cubital cell, in the paired branches of cubitus to margin, etc. Besides the type specimen from Arkansas, I have one collected by Prof. Frank Hull at Agricultural College, Miss.

The male genitalia have the lower appendages widely out- spread, the apical part about as slender as in D. tristis and with a sharp point; the superior appendages are much smaller than in D. tristis, slender, cylindric, scarcely clavate, while in D. tristis they are fully twice as broad and flattened and near tip roundedly widened.
Fore wing 19 mm. long, 7 mm. wide.
From Alaska. Type M.C.Z. No. 22658.
Arthripsodes slossonae sp. nov.
Figure 7
Body yellowish brown; antennae dark, each joint pale on base; hair on head mostly pale, but a large tuft of dark hair each side in front of eye and below antenna, and some dark on posterior warts, thoracic notum mostly with pale hair, some dark near sides; legs pale; front legs of male with the tibiae dark on inner sides, and also the tips of tarsal joints dark. Fore wings a nearly uniform yellowish brown; a snow white mark at the end of anal vein, one at base of the stigma, and faintly over end of discal cell; hind wings gray, unmarked.
In fore wings the median cell does not reach nearly as far basally as the discal cell (more subequal in transversus). The male genitalia has the clasper much as in A. trans- versus, the apical segment a little shorter, but the curved appendage is here very much shorter and stouter toward base; in length but little, if any, more than one half of the apical segment; each side of the base of the penis is a lobe fringed with stout bristles (not in A. transversus) .
