 drical spe.-ies having the basal marginal line of thorax distinct; 

 prosternum f(^eb]y channeled; inner rows of elytral punctures usu- 

 ally completely confused, the outer ones tortuous or irregular, sepa- 

 rated by more or less interrupted ridges; front thighs distinctly 

 stouter than hind ones. A numlier of the s]iecies vary greatly in 

 color and merge from one form gradually into another, so that they 

 are very difficult to classify. Of the .")() nr more s])ecies known 

 from the liiited Stat( s, the following have been taken in Indiana:
