 tated with one, often indistinct transversal fovea posteriorly before the 

 scutellum; elytra somewhat longer than pronotum, with somewhat more dis- 

 tinct and dense punctation than this, rather convexj abdomen slightly widen- 

 ed posteriorly, its first four free dorsal joints in transversal grooves 

 robustly punctated, elsewhere with very fine and scattered, and consider- 

 ably less dense punctation than the following joints, L. 3.5 mm. 



Distributed and next to aethiops our most common species; everywhere 

 however rather rare; on boggy damp forest or meadow ground.

Somewhat smaller than the preceding species, to which it otherwise is 

 very closely allied, and easily confused with. 



Black, finely haired, glistening; elytra along the suture, and abdom-

 base, the legs pitchy-red, their knees and tarsi, often also tibiae, lighter. 



Head and pronotum punctated like in uliginosa ; antennae somewhat short- 

 er than in same, but similar in structure, pronotum a little shorter and 

 quite as densely punctated and with a feeble transversal fovea poeterior- 

 ly before the scutellum, v.hich often dissolves into two small punctiformis 

 foveae. iilytra are scarcely as broad as in uli^'inosa , a little longer than 

 pronotum, very finely and densely, more distinctly punctated than same; ab- 

 domen same as in uliginosa . L. 3 mm.
