Scutellum transversely convex basally, evenly granulose throughout, or

antennae fuscous. Form attenuate, the vestiture fine, subsericeous; 

 prothorax ovate, very strongly narrowed behind, deeply canaliculate, 

 longer than wide, densely punctulate; scutellum distinctly channeled ;

 short, fine, sparse and inconspicuous; head convex, wider than long, 

 arcuato- truncate at base with widely rounded angles, the sides parallel, 

 the punctures fine, sparse but distinct; eyes rather large; occiput feebly 

 impressed along the median line; antennae extending fully to the end of 

 the elytra, thick though only feebly incrassate distally, all the joints 

 elongate, the tenth distinctly elongate and two-thirds as long as the 

 eleventh, somewhat longer than the ninth, the third much longer than 

 the first or second ; prothorax large, somewhat wider than long, rather 

 distinctly wider than the head, the sides anteriorly circularly rounded 

 to the neck, abruptly, strongly converging and sinuate thence to the 

 base, the sulcus acute and deep, not attaining base or apex, the surface 

 broadly flat and gently sloping toward the sulcus and densely and 

 strongly granulose almost throughout; scutellum sparsely and strongly 

 granose, with a strongly marked, somewhat impressed median channel; 

 elytra transverse, fully three -fourths wider but scarcely more than a 

 fourth longer than the prothorax, convex, the sides more arcuate pos- 

 teriorly, the humeri widely exposed but somewhat oblique, the punc- 

 tures very fine and sparse, close and granuliform toward the scutellum, 

 rather distinct; abdomen narrower than the elytra, parallel, sparsely 

 punctulate, the punctures coarser and more asperate basally; middle
