 c? $ . Fore wing : broad and short ; costa nearly straight, very 

 slightly and broadly arched ; apex blunt ; termen slightly convex; 

 tornus more or less rounded ; dorsum very slightly sinuate, nearly 

 straight, about five-sixths the length of the costa ; cell about half 



the length of wing ; veins 6

 base, upper discocellular there- 

 fore very short or absent, middle

 slender, subequal, slightly 

 oblique ; vein 3 from before 

 lower apex of cell, 4 from apex, 

 6 from upper apex of cell, 

 8 absent, 9 emitted from basal 

 half of 7, 10 and 11 free, 12
