Pronotum transversely striate, anterior edge bisulcate, 

 ending in a short median point. Mesonotum large, very 

 convex dorsally, anterior edge sulcate, angular in median 

 third, wing-cases reaching to posterior edge of 2nd abdo-

 high, narrowly rounded ; hind wings visible to posterior edge 

 of fore wings. 



Abdomen as a whole deflected ventrally, especially the

 segments strongly transversely ridged, ventral surface smooth. 

 Posterior edge of ord to 5tli segments with a dorsal row of 

 minute hooks, directed forwards ; 7th and 8th with a 

 crescent-shaped transverse ridge at their cephalic edge, 

 which ridge bears a row of stronger hooks, pointed posteriorly.

 wrinkled ; abd. 7 striate, abd, 8, 9 and 10 longitudinally
