NEUROPTEROID INSECTS FROM SZECHWAN — BANKS 213 



hind wing also pale, veins and fringes pale yellowish. Forewings 

 moderately slender, and the tip not broadly rounded; discal cell very 

 long, widened near tip, upper margin toward tip concave; fork one 

 not back on discal cell, but broad at base, fork two a little narrowed 

 at base, fork three scarcely back on cell, anal cell very long, as long 

 as width of wing at its end; all hairs very short. 



Legs long and slender, with but few black spines, last joint of 

 mid and hind tarsi with but few spurs, 0, 2, 2, front tarsus of male 

 much longer than tibia, its basal joint only about one half as long 

 as the second. 



Male genitalia short and inconspicuous as in Micropteima; lower 

 appendages shorter than in P. pevzovi Martynov, the upraised dark 

 hooklike processes much less stout and with slenderer tips than in 

 that species, the hind edge of the last dorsal segment roughened 

 with minute teeth. 



Forewing, male, 20 mm. long, 6 mm. wide. 



Holotype, U.S.N.M. No. 53168. Paratype in M.C.Z. 



A female differs in no important respects but is much larger, 

 forewing 25 mm. long ; the tip of abdomen shows two rather slender 

 dark-tipped processes nearly their length apart. 



From Beh Luh Din, Szechwan, August 22, 6,000 feet (holotype), 

 and near Kuanshien, October 20. It is very similar to Microptera 

 indica Mosely from Kashmir ; the lower appendages are not so much 

 narrowed toward tip, the upper lateral lobe larger, the tip of last 

 segment has black spinules instead of the pale setae of M. indica^ 

 etc. 



Genus PSEUDOSTENOPHYLAX Martynov 



Psevdostenophylax shows traces of the bristle-bearing warts on 

 metanotum and base of abdomen. In males of P. grahami are usu- 

 ally several of these warts in two rows on the metascutellum ; in 

 males of P. {Trichophylax) monticola there is a prominent median 

 patch at the base of the intermediate segment, just behind the meta- 

 scutellum. In P. ampins there are a few warts each side of the 

 middle groove at base of the intermediate segment in both sexes. 

 I do not find any in the other species. 



The species of Pseudostenophylax from Szechwan known to me can 

 be separated in the male sex as follows : 



1. Abdomen with long hair above; discal cell very long; at base of 



intermediate segment, just behind the metascutellum is a patch 



of bristle-bearing warts monticola 



Abdomen with only the usual short hair, except a tuft or crest 



at tip 2 



2. Discal cell more than twice as long as its pedicel 3 



Discal cell but little longer than its pedicel 6
