 die-groove, but at the middle with two arcuate longitudinal impressi- 

 ons (Fig. 168), separated by a narrow, smooth, somewhat convex inter- 

 val. Elytra and abdomen are distinctly and rather densely, head and 

 pronotum only simply haired. - From the likewise closely allied genus 

 Trogophloeus it differs inter alia in, that fore- and middle-tibiae in 

 outer margin are more or less spiniferous.

 Only 2 European species are known. They occur widely distributed 

 in Middle Europe and are also found in Denmark, partly in manure and 

 at rotting plants, partly under damp foliage.

Of rather equal breadth, feebly convex, of same length as, but hard- 

 ly as broad as Oxytelus piceus , recognizeable especially by the two im- 

 pressions of pronotum, and in relation to the following species by the, 

 at tip emarginated fore-tibiae.
