VTithin the group this genus is distinguished, and easily identifi- 

 ed by the antennae, which, after the long, scape-formed first joint are 

 strongly geniculate (Fig. 125). Other characteristics are: 



Labrum at middle with an acute incision, of which the corners are 

 acutely tooth-shaped; mandibles are long, sickle-shaped, two-three tooth- 

 ed; maxillary palpal fourth Joint very small and acicular, almost hid- 

 den in the end of the third, which is club-formed, and proportionately 

 large. Legs are slender, tarsi simple, first joint of hind tarsi elon- 

 gate and as long as the claw-joint, the fourth undivided. 



Only 1 species lives in Europe, which also is found in this coun- 

 try, and occurs on damp ground.
