 or only a trifle narrower than the fifth, broader than long, the middle 

 and next-last ones (5-10) almost of equal breadth, rather strongly trans- 

 verse. Pronotum posteriorly hardly a? broad as elytra, narroring anterior- 

 ly with rounded sides and obtuse hind corners, their posterior margin in- 

 side these very feebly t:B®^'^'"ved , dorsum somewhat convex, coarse, but not 

 dense punctation, intervale between punctures as broad as the punctures 

 themselves. Elytra longer than pronotum, more densely, but hardly as coars- 

 ely punctated as this; abdomen feebly tapering, all over very densely and 

 rather robustly punctated, somewhat long-haired. L. 2.5-3.5 mm. 



In bird's nests, and in hollow trees, vjhere nests have been and fresh 

 remains of these still are found; more rarely found with ants ( Formica rufa ) 

 and in fungi; distributed and not rare, especially in woodland regions.

From the preceding species, to which it in form and size is very close- 

 ly allied, it Is separated especially by the difference in pronotal punc- 

 tation, and by the color of elytra.
