CYCHRUS, Fab. 



This genus contains species of graceful, 

 sometimes slender form. The head is elon- 

 gate, the mandibles slender and prominent, 

 the four basal joints of antennae glabrous. 

 The legs are long, usually slender and well 

 adapted for rapid running. The elytra have 

 numerous striae, from 14-18, sometimes ir- 

 regular or even replaced by tubercles. They 

 live in moist woods, hiding under stones and 

 rubbish, feeding on snails, their long head 

 being well adapted for extracting the animal 

 from the shell.
