Anouium, Fabr. 



1. A. canvexifrons. Dull castaneous ; front rather convex. 2 1. long; § 1. 

 wide. Pennsylvania. 



Dull chesnut-red, slightly pubescent, finely and densely shagreened : front 

 rather convex ; eyes black ; antennae rufous, with the basal joint glabrous, 

 glossy : thorax slightly convex, each side of the middle at base with a slight 

 fovea : elytra without stria? ; feet dull rufous. 



2. A. sericans. Blackish-brown, yellowish sericeous. 2 1. long ; f 1. wide.

Anobium tkoracicum, Melsh. Catal. 



Black-brown, dull golden sericeous: head black, glossy, glabrous, much and 

 very minutely punctured ; antennas dull rufous : thorax rather gibbose, minutely 

 and somewhat rugosely punctured ; each side of the middle towards the base 

 with a small, round impression : a slight, elevated medial line : scutellum obtuse- 

 ly rounded at tip, somewhat inequal on the disk; elytra punctate-striate with 

 the punctures transverse and profound : feet dusky rufous, with the tibia? and 

 tarsi paler. Bears some resemblance to A. carinatum, Say, but it is much more 

 sericeous than that species, and the thorax is not carinate. 



3. A. obesum. Brownish-red, finely pubescent. 1-| 1. long; | 1. wide.

Anobium villosum. Melsh. Catal.
