 of pronotum, which extends across corners of mesonotum and to 

 tip of tegmina. Tegmina hyaline, opaque with waxy secretion, 

 veins white, a fuscous mark extending from base along clavus 

 to median cross vein, then along media to apical cross veins; 

 wings hyaline, opaque with waxy secretion, veins light yellow. 



Ventral edge of pygophor straight, lateral edges slightly and 

 roundly produced; anal segment long, narrow, sides straight, 

 slightly narrowing to apex; apex broad, rounded, and turned 

 ventrad, anus at apex; styles reaching a little beyond apex of 

 anal segment, narrow, slightly curved upward at apex, rounded, 

 turned inward, styles slightly compressed longitudinally, a 

 carina running from apex to base on outer surface, ventral edge

 face to front of eye and from back of eye to base of tegmen, 

 along the middle of which it is continued to apex. Tegmina 

 yellowish, opaque with waxy secretion; the fuscous mark pro-

 along media to apex ; wings opaquely white, veins white. 



Pregenital segment broader than long, posterior edge pro-
