Subfamily II. ANOB INAE. 



The insects of this subfamily are mostly of a slightly depressed, 

 sub cylindrical form, but vary to broadly oval or nearly globular. 

 The antenna? are distant at base and inserted just in front of the 

 eyes, which are rounded and usually prominent. Head deflexed 

 and nearly or quite invisible from above. Hind coxa?, except in the 

 first tribe, more or less sulcate for the reception of the femora. 

 Fall divides the subfamily into six tribes, all of which are repre- 

 sented in Indiana.
