Body extremely finely and densely punctated, oblong, feebly fusiform; 

 antennae shorter and more robust than in dubla , however scarcely thickened 

 distally, their next-last joints about as broad as long; pronotum propor- 

 tionately large, rather strongly convex, broader than elytra, with rounded 

 sides and obtuse, not retracted hind corners; elytra distinctly shorter 

 than pronotum; abdomen smoothly and not strongly tapering. L. 2-2.5 mm. 



Distributed in North and Middle Europe, but somewhat local in this 



country; most frequent in alluvium at the shores of lakes and watering places, 



also on swampy ground in forests under leaves.
