pressed, acute at the bottom, not extending quite to the apex or base ; 

 elytra wider than long, two-fifths to two-thirds wider than the pro-

 impressed for a short distance behind the scutellum, the latter with a 

 narrow entire canaliculiform parting of the granulation ; humeri widely 

 exposed, obliquely rounded; sides more arcuate posteriorly, abdomen

Large punctures of the impressions much deeper, with less extended and 

 simple floors, or, never having more than a trace of minute punctula-

Scutellum transversely convex basally, evenly granulosa throughout, or 

 never with more than a very fine inconstant, incomplete or fugitive 

 channeling 6 



4 — Color blackish, the apex of the abdomen and legs testaceous, the 



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

 prothorax ovate, very strongly narrowed behind, deeply canaliculate, 

 longer than wide, densely punctulate; scutellum distinctly channeled ;

Color black or blackish throughout, the tip of the venter not paler; elytra 



very minutely but evidently punctulate 5 



5 — Form stout, convex, the surface polished, piceous-black throughout, 



the legs dark testaceous, the antennae blackish, paler at base; vestiture 

 short, fine, sparse and inconspicuous; heart 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 fiat 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 

 coxae very remotely separated, the mesosternal process projecting 

 more than usually between the coxae, with the transverse suture
