 Elytra lata, convexa, punctato-striata, cohrata, glabra. 

 Pedes robusti ; tibiis posticis simplicibus. 



Labrum subcircular. 



Mandibles robust at tbe base, and armed on the inner margin with 

 a short basal tooth, at the apex acuminated.

 joint minute; the second dilated towards the apex and obliquely 

 truncate ; the third more robust and shorter, attenuated at the base ; 

 the ultimate joint abbreviated, conical. 



Labial palpi (Tab. VII. fig. 2n) elongate, minute ; the basal joint 

 quadrate ; the second somewhat thickened towards the apex, and 

 constricted at the base ; the third narrower at the base than the apex 

 of the second. 



Antenna approximate, situated between and below the inner mar- 

 gin of the eyes, robust, long, dilated at the apex ; the basal joint 

 elongate (extending, when placed laterally, beyond the sides of the 

 head) and gradually dilated, and inflected towards the apex ; the

 pressed, but prominent ; the sides parallel and broadly marginate ; the 

 surface is flat, inclined at an angle of 45 degrees from the plane of 

 the elytra.
