Head rather strongly raised and concave from side to side 

 between the antennae, impressed with a median groove ; front 

 large, depressed anteriorly ; epistome membranous, distinct ; 

 labrum short and transverse ; genae rather short in front but 

 prolonged downwards posteriorly ; mandibles moderately long, 

 obliquely inclined towards one another from the base to the 

 middle and then gradually incurved. Antennae about equal in 

 length to the body in the tf , shorter in the $ ; first joint acutely 

 angulate or dentate in front at the apex ; third longer than the 

 fourth; fourth to seventh subequal, eighth to tenth gradually 

 shorter ; eleventh longer than the tenth in the <S ; the joints 

 from the third of moderate thickness and more or less sharply 

 angulate anteriorly at the apex. Prothorax with a transverse 

 groove near the apex and another at the base ; strongly tuber- 

 culate near the middle of each side and often tuberculate on the 

 disc. Scutellum triangular. Elytra from two and a half to three 

 times as long as they are broad, always extended some distance 

 beyond the tip of the abdomen ; gradually narrowed posteriorly, 

 rounded or subacuminate at the apex. Legs long ; the femora 

 gradually thickened from the base to a little past the middle, 

 the hind pair not reaching to the apex of the elytra. Intercoxal 

 process of prosternum strongly arched, but not quite on a level 

 with the coxae, in the middle ; slightly dilated posteriorly, almost 

 or quite reaching to the epiniera. Abdomen with six ventral 

 segments visible in the d 1 , and five in the $ ; fifth and sixth 

 sinuately emarginate at the apex in the <$ ; fifth rounded and 

 entire at the apex in the $ . 



This genus is chiefly distin guished from Pachyteria, Serv., by its 

 less robust antennae and relatively much longer elytra. The head 

 also is shorter and less narrow in front, and the mandibles shorter 

 and more gradually curved towards the apex.
