 Mamboia {J\L\ Last) ; one example. 



The ventral segments have faint traces of a transverse sulcus in 



the middle of the fore-margin. The elytra have no traces of lateral 



carinse. The species differs irom Menigius in the maxillae being curved 



and pointed at the apex, but the hook is very short.

Differs in important characters from all the numerous genera into 

 which Chaudoir divided the old genus Scarites.
