 and hind part are flat, the sides slightly depressed, the margin

 the elytra, rough and finally pubescent, the striae of the latter 

 being thereby rendered obsolete. Legs of m. stout, anterior tarsi 

 strongly dilated.

Distinguished by its elongate shape. The head is of a bright

 antennae and palpi of a light brown, the latter being darkened to-

 which are bordered on each side by a row of minute hairs. They 

 as well as the abdomen have yellowish margin.
