This genus in its widest sense includes a Inrge number of species ; 

 more than a liundred are enumerated in the Munich catalogue, and a 

 considerable number have since been described ; they appear to be 

 generally distributed throughout the world ; they are^ as a rule, black 

 with bright red elytra, or entirely reddish, but some species are uni- 

 colorous pitchy-brown or blackish ; they are found, like so many of the 

 others of the group, in moss, at roots of grass, &c., and sometimes are 

 taken abundantly by sweeping ; from Batrisus they arc distinguished 

 (together with Ryharis) by the fact that the tarsi have only a single claw, 

 and from Bythinns by the much shorter and less conspicuous maxillary 

 palpi of which the last joint is about as long as the two preceding.
