NEUROPTEROID INSECTS FROM SZECHWAN — ^BANKS 203 



median vein is much before the base of the third cell. The male 

 genitalia has the median ventral piece with a slenderer tip, from side 

 the apical pieces are more pointed ; the process of the seventh ventral 

 segment is very broad, and shorter than in G. andle (fig. 63) . 



Length of forewing, 8 nun. 



Several specimens from Beh Luh Din, 30 miles north of Chengtu, 

 August 7-28, 6,000 feet (holotype) ; Wenchuan, November-December; 

 and Kuanshien, November 20. Holotype, U.S.N.M. No. 53161. Para- 

 type in M.C.Z. 



GLOSSOSOMA CAUDATUM Martynov 



One male from Beh Luh Din, August 7, 6,000 feet, and one from 

 Wenchuan, November. The anal area is extremely similar to that of 

 G. malayanum Banks, but in the latter the median ventral piece is 

 broad and has a long, slender tip. G. valvatuvi XJlmer is also similar 

 in anal area, but the superior pieces (seen from side) are quite differ- 

 ent ; it occurs in eastern China.

Family HYDROPSYCHIDAE 



Genus STENOPSYCHE McLachlan 



The species of Stenopsyche that are recorded below can be distin- 

 guished by the following table : 



1. In hindwings the little cell at end of the united subcosta and 



radius is incomplete ; in male the titillators ai'e forked at tip 



or have lateral projections ; larger species 2 



In hindwings the little cell is complete ; in male the titillators are 

 neither forked nor have lateral processes 3 



2. Male titillators have some lateral processes before tip ; fore- 



wings rather long, rarely with large pale areas behind grahami 



Male titillators have the tip forked ; wings broader, and usually 



with one or more large pale areas behind navasi 



3. The processes of the superior plate are rather close together at 



base, and curve downward, nearly parallel martynovi 



These processes are wide apart at base and do not curve down- 

 ward, nearly parallel 4 



4. These processes are rather long and curve toward each other 



horizontally stotzneri 



These processes do not curve toward each other, their tips far 



apart 5
