The insect is of a brown colour, the antennae lighter, the legs still 

 more, and the tarsi and palpi quite so ; the femora are dark towards 

 the apex ; the head, thorax and suture are occasionally of chestnut 

 colour ; it is as usual pubescent. The sculpture of the head in this 

 and the following species is not, as in the preceding, based upon 

 the oblong square or the oval, but rather upon the form of a ball, 

 which in a more or less compressed state is always perceptible ; in 

 some instances it is narrowed on one side. In the present species 

 the head is heavy and subglobose. The eyes are large, promiuent 

 and coarsely granulated. The antennae are inserted distant from 

 each other uuder 2 protuberances of the anterior part of the fore- 

 head. The club is 4-jointed, the joints composing it being flat at 

 the base, and, with the exception of the last, obliquely cut away at 

 the apex, the last itself being conic. The maxill. palpi have joint 

 3 rather elongated and of the form of an inverted cone, joint 4 mid- 

 dling, acuminated. The thorax is of a rounded oval shape and 

 rather strongly narrowed towards the apex. The scutellum is obso- 

 lete. The elytra have the usual rudimentary costae at the shoulders 

 and are separately rounded off at the apex. The legs are middling ; 

 2 posterior coxae inserted close together ; trochanters all simple ; 

 tibiae slightly bent at the base, narrowed and subcylindric at the tip, 

 the 4 anterior ones hairy ; tarsi with joints 2-3 subequal, the first a
