HYDROPSYCHE GRAHAMI, new species 



Plate 30, Figuke 69 



Head with some dark hair on face, on vertex pale yellowish, on 

 back of vertex some black hair each side ; pronotum with mostly pale 

 hair; antennae pale, a dark ring over joinings. Forewing with short 

 black hair, many small spots of pale yellowish hair, in apical cells 

 two rows of these spots, one each side near the vein; apical fringes 

 mostly black, no pale patches (in hedeni with pale patches). Hind- 

 wings mostly gray, with gray and black hair. 



In forewings fork one is a little longer than its pedicel, fork two 

 farther back on discal cell than in hedeni^ fork three does not reach 

 as far as apex of discal cell, fork four only a little before fork five. 



In hindwings fork one is distinct, but small. In male genitalia 

 the superior plate is broadly, deeply incised, and at each side is a 

 fairly long incurved spine; the claspers are slender, the apical joint 

 fairly long, tapering and but little curved, seen from behind the tip 

 is forked, the penis stout, tip enlarged, and from above is an out- 

 curved spine each side before the swollen tip, from the side the tip 

 is seen to have three pointed projections above. 



Forewing 7 mm. long. 



Two from Szechwan, probably Suifu, taken with a mass of H. 

 hedeni, which it resembles closely, except for the very different geni- 

 talia. Holotype, U.S.N.M. No. 53165. Paratype in M.C.Z. 



H. rhomhoana Martynov has a deeply incised superior plate but 

 without the curved spines ; the apical segment of the clasper is shorter 

 and more curved.
