there are slight variations as to the relative lengths of the seg- 

 ments ; the antennae are generally covered with slight pubescence, 

 the basal three or four segments to a much less degree. Pro- 

 thorax always much broader than long, upper surface more or less 

 convex, generally very finely punctate ; lateral margins always 

 somewhat explanate and concave, more so than in Hyphasoma ; 

 the anterior lateral angles not so produced as in Hyphasoma; at 

 each of the anterior and posterior angles is a fine seta arising from 

 a pore with a slightly elevated base. Scutellum always triangular, 

 with the surface always impunctate. Elytra somewhat broader 

 at the base than the prothorax; upper surface confusedly punctate, 

 the punctures being generally stronger than those of the pro- 

 notum, but in some cases the punctures are finer on the apical 

 part ; sides often slightly explanate, and sometimes the edges bear 

 remotely distributed tine setae. Underside : posterior femora 

 strongly incrassate; posterior tibiae generally short, ending in a 

 sharp spine; first segment of posterior tarsi generally short, claw- 

 segment always inflated ; bilobed segment of the front and middle 

 tarsi broad, broader than that of the posterior tarsi. 

 Range. Asia, Africa.
