The species live on damp ground at strand and lakes under stones, 



in alluvium and the like, and are natives especially of highland and 



mountain regions. Of the few European (5) species 2 are distributed in 



North Europe, and one of these is very local in this country.

(Fabr. Ent. Syst. Suppl. 180; Erichs. Kraatz Ins. D. II, 925: Thorns. 

 Skand. Col. Ill, 181; Rey Brevip. 1880, 57; Janglb. Kaf. U. II, 711). 



Considerably larger than Lesteva longelytrata 3oeze ( bicolor Er.), 

 but of same form as this; ordinarily easily identified inter alia by the 

 color of elytra, which however somewhat varies. 



Black, glistening, distinctly and rather densely gray-haired; elytra 

 most often with a red, more or less spreading longitudinal spot at middle, 

 more rarely entirely black (var. nigrita Mull); antennae and legs brown- 

 ish-red or blackish-brown; femora and tarsi in the typical form most oft- 

 en reddish yellow or yellowish-red. 



The head in both sexes narrower than pronotum, with rather scattered 

 and robust punctation, forehead between the rather large, protruding eyes 

 deeply impressed, in the impression with two feeble longitudinal grooves 

 and bach of these two distinct ocelli, temples shorter than eyes, rounded 

 off, antennae long and slender, much longer than head and pronotum to- 

 gether, their first joint thickened, the following all longer than broad, 

 the second shortest; pronotum narrower than elytra, cordate, with rect- 

 angular hind corners, slightly convex, with rather dense and robust punc- 

 tation, and with a transversal fovea posteriorly in front of scutellum; 

 elytra more than twice as long as pronotum, broadened posteriorly ana
