 The body flat; head anteriorly narrowing, almost triangular; an- 

 tennae slender and rather fine; pronotum posteriorly narrowing, its 

 fore-corners projecting and rather sharp; anterior femora, like those 

 in following genus, the ventral margin obtusely tooth-f ormedly dilat- 

 ed (cf. Fig. 126); fore-tibiae strongly broadened toward tip, at middle 

 with a convex process opposed to the tooth of the femora; fore-tarsi 

 in both sexes strongly dilated; posterior femora often thickened, hind 

 tarsi proportionately thin, their claw-joint long, as long as the four 

 preceding joints together. The foremost abdominal ventral joints with- 

 out carina in middle-line. - For the rest this genus is very closely 

 allied to the following. 



A number of species belonging to this genus are distributed in the 

 countries bordering the Mediterranian sea, a few in Liiddle Europe; of 

 these 1, perhaps 2, in Denmark. They live on damp ground under moss and 

 stones, and at the root of plants.
