 is not deeply cleft at middle, but only with an angular incision, 

 that elytra has a deep sutural jjroove, that the abdominal transversal 

 impression at base of the joints are double, and that hind-tibiae are 

 not spiniferous. - Besides a fev; fine marginal punctures anteriorly 

 pronotum has on each side a large dorsal puncture some distance from 

 the anterior margin, and an other oack of the middle; the ante sternal 

 plate at middle-line not grooved or carinated. 



In Middle Europe are found 3, of which in Denmark, Sweden and Nor- 

 way 2, closely allied species. They live in hollow trees in wood-crumb- 

 lings and under bark.

In several respects somewhat variable; but in relation to the fol- 

 lowing species easily identified, particularly by few punctures of the 

 temples, the antennal proportionally rather long third joint, and by 

 the distinct punctures of elytra.
