the prothorax, sharply and rather finely and densely punctate; eyes rather 
large, circular, midway in height; rostrum moderately stout, a little arcuate, 
longer than the prothorax, but distinctly shorter than head and prothorax 
together, apparently smooth. Prothorax without postocular lobes, nearly 
twice as high as long, regularly but not rapidly tapering from the base, 
coarsely punctate. Under side of body similarly but much more feebly 
punctate, the femora lightly punctate. Elytra striate and very coarsely 
and very feebly punctate in the interspaces.

PE var, Pigs 3: 
Body regularly ovate, about twice as long as broad. Head short but full, 
less than one-third as long as the thorax, sharply and finely punctate; eyes 
rather large, circular, midway in height; rostrum moderately stout, a little 
arcuate, longer than head and thorax together, apparently smooth. Pro- 
thorax with no sign of postocular lobes, about half as high again as long, 
regularly but not rapidly tapering, with little fullness, the surface coarsely 
and rather densely punctate, most coarsely on the lower part of the sides. 
Under surface of body punctate like the lower sides of the prothorax, the 
femora more or less punctate. Elytra punctato-striate, with feeble punctu- 
ation in the interspaces.
