 breadth or only tapering posteriorly, finely haired, with rather 

 robust and dense punctation with elongate, posteriorly inserted 

 punctures; middle of first free joint is smooth. L. 3.5-5.5 mm. 



Distributed throughout the greater part of Europe; typical form 

 rather frequent here on all kinds of damp ground. Var. longulus, 

 which is rare, is now and then found together with the typical form; 

 var. bimaculatus is very rare (at Madum Lake south of Aalborg in allu- 

 vium). - Both varieties are connected with the typical form by in- 

 termediates.

Fusiform, of same size as punctus and easily identified among
