Subgouital plate slightly longer than basal width, styles elongate, flattened 
margin weakly convex and slightly over half as long as one of the styles. 
Cephalic coxae slender, strongly carinate, unarmed. Cephalic femora with 
ventro-external margin armed w'ith four, and one genicular, spines; ventro- 
internal margin wdth the following si)ine formula, ililililiiiill. Cephalic 
tibiae with five external and ten internal spines on the ventral margins, which 
increase gradually in size and length distad. Median and caudal femora

portions at the true veins blackish (except at the ulnar and first branch of the 
median vein), these flecks conspicuous and reproduced in the homologous 
Ijortions of the wing, but there obsolete proximad at the median vein and 
weak at that vein distad. Wings transparent, iridescent, showing scarcely 
any l)rown tinge except from the humeral vein to the costal margin, where 
they are weakly tinged with tawmy olive. Abdomen dorsad clay color,
