One of our largest species, rather broad and robust, with pro- 

 portionately slender antennae, otherwise easily identified by the 

 yellow side-margin of the black elytra. 



Black, head ana pronotum specular shining i elytra with dull shine, 

 as \*ell as the abdomen with fine, black hair, the latter often with 

 greatly changeable color; the defloxed side-margin ©f- elytra reddish- 

 yellow; posterior margins of abdominal joints occasionally brownish; 

 antennae brown, their first joints, and mouth-parts yellowish-red; 

 the legs dark-brown with somewhat lighter tibiae and tarsi. 



The head rounded; the hindmost large puncture of the forehead is 

 placed close to posterior margin of the eye; antennal outer joints 

 as long as broad; pronotum broader than elytra, depressed at sides, 

 with three punctures in each dorsal row, and scattered punctures on 

 side-planes; elytra as long as pronotum, with fine and rather dense 

 punctation, ground-surface extremely finely shagreened, and therefore 

 more or less dully shining; abdomen narrowing toward the tip, punc- 

 tation like that of elytra. L. 10-12 mm. 



In the & the abdominal fifth ventral joint with a very small, 

 the sixth with a deep triangular incision at tip, which is continued 

 forwardly by a cuneiform, smooth groove. 



In Denmark not rare in the autumn, at decaying fungi; mainly in 



woodland regions; distributed in Europe.
