veolatus, rectangulatus. Pedes tibiis elongatis basi apiceque arcua- 

 tis. 



Of the usual brown colour, legs and antennae lighter, tarsi and 

 palpi quite so, femora nigrescent at the apex, hairs of occiput and 

 thorax rather long. The former slightly narrowed behind, the head . 

 thus of a somewhat rhomboid form. Antennal club composed of 

 3 joints, the 2 first 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 

 subcylindric 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 elongated in certain in- 

 dividuals 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 colour which is 

 chestnuD, darker at the base and suture of the elytra, and light, 

 more or less brownish or yellowish, below ; the antennae being of the 

 latter colour with a nigrescent club. The occiput is slightly narrow- 

 ed, the head altogether plump, heavy and transverse. The antennal 

 <elub is composed of 3 subglobose joints the last of which is acu-
