NEUROPTEROID INSECTS FROM SZECHWAN — BANKS 217 



Length of f orewing, female, 12.5 mm. ; width, 5 mm. 



Length of forewing, male, 11 mm.; width, 4.5 mm. 



Two from near Washan, 4,000 to 6,000 feet, July. Although the 

 discal cell is short in this and P. mimicus^ I keep them in this genus 

 because they are very closely related to P, minimus^ which has a long 

 discal cell. Holotype, U.S.N.M. No. 53171. Paratype in M.C.Z. 



PSEUDOSTENOPHYLAX (TRICHOPHYLAX) MONTICOLA, new species 



Plate 29, Figures 37, 38, 51 



Face rufous, with black hair ; vertex nearly black, also with black 

 hair; basal joint of antennae pale and with pale hair, beyond the 

 segments are darkened above; palpi pale, second and third joints 

 equally long, mesonotum black on sides, more rufous through middle, 

 hair black ; metanotum rufous, darker above wing base ; abdomen dull 

 brown above, with innumerable distinct pits, larger than usual, and 

 each with a long white hair, about one third as long as the segment, 

 a few near middle of length longer, at tip a tuft of long hair as 

 usual; venter more yellowish; legs pale, front and mid tibiae with 

 black spots, and the tips of tarsal joints dark, many black spines. 



Forewings rather densely clothed with short black hair, posterior 

 part of wing from cubitus back is brown, and with some pale spots, 

 one much larger near end of anal cell; apical veins with irregular 

 brown spots along each side; hindwings with short black hair in 

 front, paler behind, fringes short and pale. 



Forewings rather short and broad toward tip (much like 2\ rotundi- 

 pennis)^ fork one is back on discal cell about twice as far as in 

 T. rotundipennis, fork three also reaching farther back; discal cell 

 even longer, its pedical no longer than cell width, and the discal cell 

 not widened at tip. Male genitalia show below a rather long piece 

 each side, obliquely truncate, and with long yellowish hair ; the supe- 

 rior pieces (from side) are short and moderately broad, not pointed, 

 the intermediate appendages have a pair of slightly curved slender 

 black prongs directed upward; the penis sheaths have the terminal 

 piece slender, curved, and with long hair at tip (like Pseudostenophy- 

 lax) ; tip of last dorsal segment with a triangular depressed area, 

 covered with minute black denticles. Tip of female has the two 

 slender tipped pieces common in Pseudostenophylax^ only slightly 

 separated; these arise from a rather large base, and below (from side) 

 is an elongate lobe, and at lower side, an elevated ridge, projecting 

 most prominently below. The hairs on the abdomen of the female are 

 only a little longer than usual in the family. 



Length of forewing, 17 to 22 mm. ; width, 7 to 8.5 mm.
