 margined inside inner rim of the eye, antennae short, and robustly thick- 

 ened distally; pronotum in the o narrower than elytra, in the d*as broad 

 as these, and nearly twice as broad as long, broader than in the q , 

 in both feebly narrowing posteriorly, feebly convex, on sides flatly and 

 broadly impressed, and densely and rather robustly longitudinal-rugose, 

 at middle with isolated, feebly longitudinal-rugose punctation and with 

 three grooved: one middle-groove and two feeble, slightly outwardly cur- 

 ved side-grooves, their intervals flat. Elytra a little longer than pro- 

 notum, densely and rather finely longitudinal-aciculated- or longitudinal- 

 rugose-punctated; abdomen very finely shagreened, with scattered and very 



fine punctation, sparsely haired. L. 3-4 mm.

 In the O the sixth ventral abdominal joint at middle slightly impress 



sed and posterior corners of impression prominent short dentiform. Post- 

 erior margin of seventh joint with two rather deep and broad curves, sep- 

 arated by a short, rounded interval. 



Distributed in Middle Europe, but rarely in the northern part; in
