Elongate, slender. Piceous; head blackish; base of anteniue and part 

 of abdomen dull yellow. Head wider than thorax; eyes very large, convex, 

 prominent. Antemue rather stout, reaching beyond tips of elytra, second 

 and third joints equal. Thorax one-half wider than long, sides narrowly 

 margined, impressed near front angles, which are rounded. Elytra two-
