The body is rather flatly depressed and evenly broad, narrow; the 

 head narrower than pronotum, constricted behind, with distinct, even though 

 short temples, rather large and convex eyes, and the vertex with very 

 small ocelli, impressions of forehead feeble or obliterated, antennae 

 short and rather robust, of even thickness or very feebly thickened dis- 

 tally, distal joint of maxillary palpi much longer and not finer than 

 the short third joint, gradually tapering. 



Pronotum is broadest anteriorly and about as broad as elytra, feebly 

 narrowing posteriorly, with slightly rounded, finely margined sides, slight- 

 ly convex, without distinct impressions; elytra about twice as long as 

 pronotum, with almost parallel sides; abdomen of equal breadth, upturn- 

 ed broad-margined; legs rather short, tibiae finely and sparsely spini- 

 ferous, hind tarsi rather elongate, nearly as long as tibiae, their claw- 

 joint at most as long as, most often shorter than the first four joints 

 together. 



The species live in hollow trees and stubs, under bark, in affal in 

 cellars, stables and outhouses, in old straw etc. In Denmark 3 species 

 are found, which are distributed in Middle and North Europe.
