verse. Elytra scarcely more than one-fourth longer than wide, a little less 

 than twice as long as the prothorax, and, at the small and feehly tumid 

 humeri, but slightly wider than the latter ; sides behind the humeri very 

 feebly convergent, the apex broadly, almost semi-circularly rounded ; disk 

 with moderately coarse, very deep, abrupt, finely remotely and very feebly 

 crenulate grooves, the intervals at least twice as wide as the grooves, flat, 

 each with a series of small, moderately distant, somewhat transversely rugu- 

 lose punctures, which are more or less confused on the second, third and fifth ; 

 setae small but distinct, silvery. Abdomen finely, feebly, sparsely punctured, 

 the seta? of the under surface quite robust, pale and distinct. Legs very 

 short, robust, black, finely and sparsely punctured ; claws moderate. Length 

 3.7-4.5 mm. ; width 1.9-2.3 mm.

The type is a female judging by the entirely unimpressed abdo- 

 men, but in several of the species allied to this in general habitus, 

 the male sexual characters become very feeble, so that it is occa- 

 sionally difficult to determine the sex of isolated individuals. The 

 present species is widely distinct although somewhat allied to nitida; 

 it may be known, however, by its black legs, finer pronotal punc- 

 tures, less rhomboidal form of the body, larger scutellum, closer and 

 more transversely rugulose interstitial punctures, and more evident 

 setae. The anterior coxae are separated by one-half of their own 

 width.

Oblong, robust, convex, black throughout, the legs somewhat 

 piceous, polished and feebly aeneous, the beak very short, not at all 

 over one-half as long as the prothorax in the female, the prothorax 

 large, one-fourth wider than long, subparallel, strongly rounded and 

 extremely convergent near the apex, the base fully three and one- 

 half times as wide as the head, the disk without median line, the 

 punctures rather coarse and impressed, separated by twice their 

 own diameters. The elytra are but slightly longer than wide and 

 two-thirds longer than the prothorax, coarsely, deeply striate, the 

 grooves distinctly crenulate, becoming deeply and conspicuously so 

 toward base ; intervals flat or feebly convex, scarcely one-half wider 

 than the grooves, each with a single series of rather small but deep, 

 moderately distant punctures, the third very much wider than any 

 of the others and with the punctures sparse but confused. Length 

 4.3 mm.; width 2.2 mm.
