Head vertical, and quite variable, grooved, flat, tuberculate or 

 simply convex behind; epistoma emarginate in front and narrowed 

 by the antennal cavities, cheeks unarmed or with an obtuse tooth on 

 each side ; antennal cavities rather large, oblique and prolonged into 

 a groove in front and situated at some distance from the eyes. An- 

 tennae variable, often short, and dentate from the fourth or fifth 

 joint, and not inserted in a groove in the prosternum while in repose ; 

 first joint rather elongate and robust; second, third, and sometimes 

 the fourth short and feebly clavate; the following joints triangular, 

 dentate on the inner side, and armed with a terminal poriferous 

 fovea. Eyes large, oval, parallel on the inner margin (sometimes a 

 little more widely separated in front than on occiput). Pronotura 

 wider than long, rather convex, broadly emarginate or bisinuate in 

 front; sides more or less arcuate, with two distinct margins, the 

 inner one abbreviated and joined to the outer one posteriorly; base 

 bisinuate, with a broad median lobe, more or less truncate, rounded 

 or emarginate in front of scutellum ; surface with or without impres- 

 sions, and sometimes with a distinct lateral carina near posterior 

 angles. Scutellum broad, acute posteriorly, and sometimes trans- 

 versely carinate. Elytra elongate, sinuate at base, with or without 

 longitudinal costae; humeri prominent; sides sinuate, and often not 

 covering the sides of the abdomen; apex very variable, sometimes 

 expanded, acute, broadly rounded, or strongly dentate. Sternal 

 cavity formed by the metasternum and mesosternum, the former 

 arcuately emarginate in front. Mesosternum divided, the lateral 

 branches very short. Prosternum wide, and more or less lobed in 

 front ; anterior margin truncate, rounded or emarginate ; prosternal 

 process broad, with the apex acute, truncate, rounded or expanded. 

 Middle coxae not more widely separated than the anterior ones; pos- 

 terior coxae short, slightly dilated internally, narrowest at middle, 

 and strongly dilated anteriorly at the lateral margin. Abdomen 

 sometimes visible from above. Legs slender; femora fusiform, not 

 dentate on inner margin, and frequently more strongly swollen in the 

 male than female ; tibiae slender and subcylindrical, the anterior ones 

 sometimes ciliate; tarsi long and slender, and the joints armed with 

 distinct lamellae, first joint of posterior pair as long or longer than
