behind, the head thus of a somewhat rhomboid form. Antennal 

 club composed of three joints, the first two of which are strongly- 

 globose, the last being acuminated and slightly cut away on 

 one side at the apex. The mandibles are furnished with an 

 acuminated tooth at the middle, bent at the apex, and, what 

 is rather uncommon in this g., gradually enlarged towards the 

 base. The thorax is obconic, rather longer than broad. The 

 elytra are somewhat more stretched than usual in this group, 

 the rudimentary humeral costae are rather prominent, they 

 are separately rounded off at the apex. Tibiae, more or less 

 elongated, slightly bent at the base and apex, at the latter 

 place sub-cylindric and hairy. Tarsi with joints 2-3 subequal, 

 first pair slightly contracted. A sexual distinction appears to 

 be expressed in the length of the tibiae, which are less elon- 

 gated in certain individuals, which are at the same time less 

 robust than the others. The insect is easily distinguished by 

 its general appearance.

A pretty little species, at once distinguished by its color, 

 which is chestnut, darker at the base and suture of the elytra, 

 and light, more or less brownish or yellowish below, the 

 antennae being of the latter color with a nigrescent club. 

 The occiput is slightly narrowed, the head altogether plump, 

 heavy and transverse. The antennal club is composed of 3 

 subglobose joints the last of which is acuminated and slightly 

 cut away on one side as in some of the preceding species. 

 The thorax is obovate, broadest below the middle and gradu- 

 ally narrowed towards the apex. The elytra have the usual 

 two shoulder-ridges and are rather strongly dehiscent at th©
