 Large, broad species, having the color black, the thorax and 

 elytra usnally l)ordered with bhie; thorax broad, with distinct liind 

 angles; elytra rounded or snbacnte at apex; fi'ont tibite palmate. 

 They occur beneath stones, logs and rubbish in open woods and 

 along the borders of cultivated fields, preferably in sandy places, 

 ;ind feed upon larvte of various kinds, (^specially those of tbe army 

 worm. For this reason they are to be classed among the most bene- 

 ficial of the Carabida'. Eleven species are known from the United 

 States, four of which have been taken in Indiana. The principal 

 papers treating of the genus are as follows:
