ovate and acuminate — these organs vary to a certain extent ; the 

 abdomen is nearly always more or less marginate, the hind coxae far 

 apart, and the first ventral segment concealed under the metasternum ; 

 the tarsi have one single claw ; the under part of the head bears 

 nearly always a large, more or less obtuse, longitudinal carina. 



This tribe is widely distributed throughout the world, but it has, 

 comparatively speaking, few representatives in South Africa.

Body short, convex ; antennae eleven- jointed ; maxillary palpi of 

 moderate size, second joint clavate at tip, third globose, minute, 

 fourth briefly oblong, obtusely acuminate ; prothorax cordate and 

 with three foveae connected by a transverse sulcus ; elytra with a 

 sutural and a dorsal stria, the latter more or less abbreviate, lateral 

 margin sulcate inwardly ; abdomen marginate. 



Owing to the epipleural sulcus of the elytra and the transverse 

 sulcus of the prothorax, this genus has been removed from Br y axis.

 seventh joints subelongate, decreasing in length, eighth nearly 

 quadrate, club triarticulate ; prothorax much broader than the head, 

 nearly as long as broad, subcordate, lateral foveae large, median one 

 small, transverse sulcus angular ; elytra a little longer than broad,
