(Erichs. Kaf. Mk. Er. I, 310; Iren. Spec. Staph. 69; Kraatz Ins. D. 

 II, 226; Ivluls. et Rey Brevip. 1875, 377; (Janglb. Kaf. M. II, 242). 



A little smaller and less glistening then carbonaria , as a rule with 

 lighter antennae and legs; furthermore the antennae are a little short- 

 er and more robust, and pronotum broader. 



Black, modulated gloss; elytra often brownish; antennae brownish, their 

 base, mouth-parts and legs reddish yellov-. 



The entire body is dorsally extremely finely and extremely densely 

 punctated, and with very dense grayish glistening hair vestiture; the 

 head distinctly narrower than pronotum, slightly convex, most often vjith 

 a small fovea at middle; the antennae rather short, feebly thickened dis- 

 tally, their third joint shorter than the second, the next-lest about 1^ 

 times as broad as long, distal joint hardly as long as the two next-last 

 joints together, tapering. Pronotum is somewhat narrower than elytra, 

 nearly Ij^ times as broad as long, with anteriorly slightly rounded sides 

 and not narrowing posteriorly, slightly convex, with a feeble fovea pos- 

 teriorly before scutellum, and sometimes slightly grooved at middle-line; 

 the elytra about '^1? longer than pronotum; abdomen rather evenly broad, its 

 foremost dorsal joints somewhat more robustly punctated in the transverse 

 grooves than on the rest of the dorsal surface of the joints. L. 2.5 mm. 

 In the O the sixth ventral joint of abdomen is somewhat elongate and 

 rounded off at tip, in the p not elongate and triangularly incised at tip.
