transversely rugulose. 
Head : length of clypeus and labrum together about equals breadth of 
clypeus ; malar space about as long as two-thirds the diameter of an ocellus ; 
antenna 12-segmented, not club-shaped, but subserrate, the segments from 4 
onwards being of equal breadth apically, but each one being very broad apically 
and narrow basally, so that the breadth basally is about two -thirds the breadth 
apically ; median fovea as a deep rounded depression ; vertical furrow clearly 
marked. 
Legs with hind basitarsus equal to three following tarsal segments 
together ; inner hind tibial spur about five-sevenths length of basitarsus ; 
Abdomen with hypopygium set ujj erect, with the hind margin slightly two-lobed,.
