elevated ridges running from the root of the antenna) a short 

 distance upwards, a third runs from the crown of the head 

 down towards the centre of the two former, but all three reach 

 only about the middle of the head. The part below the 

 antenna? is covered with white hair. The antenna? have the 

 3rd joint much elongated and the terminal club composed of 

 elliptic joints, The thorax is rather slender, incrassated at 

 the middle, gradually narrowed in front but nearly quadratic 

 behind. The elytra are longer than the thorax, about double 

 its breadth and oval, being slightly narrowed at the shoulders 

 and the apex. The legs are long and slender, hairy at the 

 apex of the tibia? and the tarsi, the latter very much so on the 

 inner side. The insect is of a metallic black color highly 

 polished; the legs, palpi and the first two antenna! joints are 

 whitish, the tibia? and the apex of the palpi being, however 

 rather darker, joints 3-11 of the antenna? are brownish, the 

 coxa? and the mouth are yellowish, the tarsi have a brown 

 spot at the apex of the first 3 joints, the claws are black. The 

 insect is punctured all over, but the abdomen, the apical seg- 

 ments of which are indeed nearly smooth, less so than the rest 

 of the body, and sparingly covered with small white hairs.
