Subfamily II. COMPLICATA. 



This group contains by far the greater lutmber of the species 

 lielonging to the family. All agree in having the middle coxal 

 cavity enclosed by four distinct pieces. The beetles vary much in 

 form and size, and exhibit the most perfect development of the oar- 

 like hind legs. Four tribes occur in the Morth American fauna, all 

 of which are represented in Ind'ana.
