 Eriehs.. all described by Casey in his Revision, and it is probable 

 that a number of them will prove to be synonymous. His types of 

 these species were from points mostly in Michigan, which would 

 render their occuri-ence in Indiana, especially the northern por- 

 tion, very probalile. though as yet specimens have not been taken. 



Division D. 



Tn this group the elytra are sculptured a.s in Division C, but the 

 thorax is without an impression along the median line. The beetle, 

 says Casey, "sh(mld be held in such a manner that the light will 

 pass obliquely across the highest point of the thorax and perpen- 

 dicular to its longer axis. Tf there is no sign of even a narrow 

 longitudinal shade, the species belongs to this division. If there 

 be even a faint shadow extending along the middle of the disk, the 

 insect may lie ecmsidered as belonging to Divisicm C."
