 abdominal tip. Legs are more or less slender ; coxae 6mall, fore-coxae 

 rounded conically, contiguous, hina coxae separated by a rather broad 

 lobe of the metasternum; tibiae without spines, tarsi 5-jointea. 



In Europe only 2 genera are found, of which the species are partly 

 also distributed in this country; they live preferably on damp ground. 



Key to ienera. 

 1. The eyes do not occupy the entire sides of the head, and the temp- 

 les are about as long as the eyes. Abdominal tip with two long 



distal bristles 88. Eianous Sam. 



The eyes occupy sides of head entirely, temples vanished. Abdomi- 

 nal tip without distal bristles 89. Stenus Latr. 



88. Jenus Eianous Sam.

In form of body and appearance, in construction of antennae and 

 maxillary palpi , also in number of tarsal joints etc., Eianous cor- 

 responds mainly with Stenus . -(Page 480) It differs from same mainly 



in that the strongly protruding, round eyes are only half as large as 

 sides of the head, so that the temples, which are placed obliquely be- 

 hind them become almost as long as the eyes, and that the abdominal 

 seventh ventral joint is endowed with two long, stiff bristles at tip, 

 which extend far out from the abdominal tip. The palpiger of labium 

 is short, and cannot like in Stenus be produced by pressure or at will.
