still more so, the tarsi and palpi very light ; 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 pre- 

 ceding, 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 subglo- 

 bose. The eyes are large, prominent, and coarsely granulated. 

 The antennse are inserted distant from each other under two 

 protuberances of the anterior part of the forehead. The club is 

 four-jointed, the joints composing it being Hat at the base, and, 

 with the exception of the last, obliquely cut away at the apex, 

 the last itself being conic. The maxillary palpi have joint 3 

 rather elongated, and of the form of an inverted cone ; joint 4 

 middling, acuminated. The thorax is of a rounded-oval shape, 

 and rather strongly narrowed towards the apex. The scutelhini 

 is obsolete. The elytra have the usual rudimentary costae at the 

 shoulders, and are separately rounded-otf at the apex. The legs 

 are middling; two posterior coxse inserted close together; tro- 

 chanters all simple ; tibiae slightly bent at the base, narrowed 

 and subcylindric at the tip, the four anterior ones hairy ; tarsi 

 with joints 2-3 subequal, the first a little longer and the fourth 

 shorter, the two anterior ones slightly contracted. I include in 

 this species some individuals which slightly differ from the fore- 

 going description, being more robust, covered more densely and 

 with longer hair, especially on the occiput and thorax, with the 

 latter rather obcouico-ovate, and the costa of the elytra more 

 distinct, and, moreover, occasionally of a chestnut colour.

Less robust than the former, and further distinguished from 

 it by the seventh antennal joint (the one preceding the club), 

 which is of a strongly cylindric shape, by the minuteness of the 

 last joint of the maxillary palpi, the obtuse and nearly obsolete 

 tooth of the mandibles, the short conical form of the thorax, 

 and the tibia?, which are slightly bent at the apex.
