 at basal third in hindwing; Rj+g forked at basal fourth in forewing 

 and at basal fifth in hind. Five R1-R2+3 crossveins in forewing, 

 four such veins in hindwing. Hyaline stripes broad.

 (10) extending just beyond base of ninth tergite, acute; left process 

 (10 LP) straw yellow, inner "talon" not strongly curved but well 

 separated from the thin outer portion, which is parallel-sided, acutely 

 pointed apically with a central carina extending beyond margin; 

 major right process (10 RPi) large, dark brown, inner basal angle 

 acutely produced, distal apex blunt, straight. Hypandrium (H) well 

 developed. Sides equal, right apical angle membranous, this area ex- 

 tending mesobasad but diminishing; process (HP) broad basally but 

 abruptly narrowed midway distad, apex truncate. Left paraproct

 sclerotic, terminated bj'^ a pair of stout "claws" on a bulbous base; 

 ventral lobe finger-shaped, elongate, well sclerotized beneath, mem- 

 branous above; foramen with one dorsal, and two ventral projec-
