XI. DYSCHIRIUS Bon. 1813. (Gr., "bad + hand.") 



Small black or bronzed, shining species, having a globular thorax 

 and flat bowed mandibles. They live in burrows in wet sandy 

 places, along streams and lakes and may be taken in the evening, 

 when they run freely about, or at any time by pouring water over 

 their burrows, which causes them to emerge. About 40 species are 

 known from the United States, eight of which have been taken in 

 Indiana, while two or three others perhaps occur. The principal 

 papers on this and the next three- genera are as follows:
