Mentum ampliate-rounded laterally, slightly narrower at the 

 ligular part the anterior margin of which is rounded and very 

 deeply notched in the centre, palps cavity very broad and long, 

 upper face considerably narrower than the inner, maxillae robust, 

 inner lobe sharply angular at tip in the $ , but with a sharp 

 incurved tooth in the ? and densely pubescent inwardly in both, 

 upper lobe long, styliform sharp at tip but not hooked, in either sex 

 thickly penicillate ; clypeus of the $• produced laterally in front into 

 two moderately long, almost erect sub-triangular teeth, the centre 

 of the anterior margin is developed into a long incurved horn ending 

 into a bifurcate divaricating process of variable length ; in the $ the 

 clypeus is simple, somewhat short, slightly wider at apex than at 

 base and very weakly sinuate in the anterior margin ; prothorax, 

 sub-diagonally ampliate-rounded from the apex to about the median 

 part, sub-parallel there, weakly sinuate along the base on each side 

 of the scutellum, but almost straight above it ; scutellum normal ; 

 elytra elongated, plainly attenuated behind, being only across the 

 apex not more than half the width of the base ; metasternal process 

 horizontal, triangularly aculeate, the metasternal separated from the 

 mesosternal by a suture ; anterior tibiae bi-dentate outwardly and 

 with a strong serration inwardly in the $ , tri-dentate outwardly 

 and simple inwardly in the $ ; fifth joint of anterior tarsi glabrous 

 in both sexes. 



The genus is represented in Africa by several species and 



numerous varieties.
