A small species, closely allied to Argus and like this with finely 

 marginated abdomen, but with shorter elytra, more robustly punctated 

 thorax, and most often with lighter legs. 



Black, rather glistening, with especially fine and short, whitish 

 hair; base of maxillary palpi yellow; legs lighter or darker brownish red. 



Head is broader than pronotum, as broad as elytra, dense and robust 

 punctation; forehead between eyed scarcely impressed, but with two flat- 

 tish broad grooves, separated by a flattish convex interval; antennae 

 rather short; pronotum broadest before middle, somewhat narrower than 

 the elytra, longer than broad, narrowing posteriorly, and with anterior- 

 ly slightly rounded sides, convex, densely and very robustly punctated, 

 without impressions and without groove in middle-line; elytra as long as 

 or a trifle lonjer than pronotum, with hardly as dense, but equally ro- 

 bust punctation as pronotum, slightly convex, smooth or almost smooth; 

 abdomen smoothly tapering, rather round with peculiarly fine side-mar- 

 gins especially in the © ,with rather dense and fine, posteriorly finer 

 punctation, its foremost free dorsal joint at base with four small ca- 

 rinae; hind tarsal second joint longer than the third. L. 2.5 mm. 



In the O^ the abdominal sixth ventral joint at tip feebly emarginate. 



Distributed in Middle and North Europe; in this country everywhere 

 rather rare; on damp ground and in alluvium at lakes and water-courses.
