(III. Antenna' with two itasal juints glai)rons. Noma Kirns. 



Of these only specimens of t'lichrus have as yet been taken in 

 Indiana, though two or three species of Xo)iKir(ltis should l)e fonnd 

 here. They are black or violaceous in color and 10-18 mm. in 

 length. 



II. Cychri'S Fall. 1794. (Gr., "a ground rniuier.") 



Beetles of medium or large size, violaceous or brownish-i)nrph' 

 in color. ha\'ing the head elongate, the mandibles long, slender. 

 ( urved and without a 'hristle-bearing piuictnre on the outer side; 

 labial and maxillary pal|)i very long, the last .joint hatchet-shaped 

 and concave. The elytra have 14 to 18 very distinct stria\ which 

 are sometimes irregular or replaced by tubercles. The species live 

 beneath stones and leaves, usuallv in moist woods, and feed upon 

 snails, their long heads having, in the course of time, become especi- 

 ally adapted to extracting these animals from ihoiv shells. For 

 synopses of the gentts see :
