IX. PASiiiACJTL-s Bon. 1813. (Gr., "all + fight.") 

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

 elytra usually bordered with blue ; thorax broad, with distinct hind 

 angles ; el.vtra rounded or subai-iite at apex ; front tibiaj palmate. 

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

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

 and feed upon larvae of various kinds, especially those of the 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:
