distinguished by its being more densely punctate, the eyes less

 punctate; meso- and metasternum punctate, the punctures densest 

 at the sides and almost invisible in the middle. 



Head longer than the width at the base; eyes large, prominent, 

 the width across them a little more than that of the prothorax; 

 antennae slender, inserted immediately in front of the eyes, not quite 

 reaching posterior coxa?; 1st and 4th joints each as long as 2nd- 

 3rd combined, 3rd shortest, 4th-10th obconic, very gradually 

 decreasing in length, 11th not much wider than the others and 

 one and a half times as long as 10th. Prothorax transverse, 

 rounded in front, the sides behind almost parallel, truncate at 

 base; on each side of the middle of the base there is a large 

 shallow elliptical oblique imj^ression or fovea; an impression on 

 each side stopped in the middle by a dumb-bell-shaped, almost 

 impunctate elevation. Elytra much wider than prothorax, 

 shoulders slightly rounded, sides almost parallel to near the apex, 

 a shallow arcuate impression behind the base. Posterior femora 

 hardly thicker than the others; tibiae feebly curved, the posterior 

 compressed, dilated towards and emarginate at apex; posterior
