 Indiana.

Form of cam if ex. Uniform coppery above; piceous, feebly bronzed be- 

 neath; palpi, stem of antennae and tarsi reddish-brown; club of antennae 

 darker. Clypeus rounded, margin elevated; vertex in female transversely 

 elevated, in male armed with a short, compressed acute horn. Thorax of 

 male with disk flattened and triangular, finely scabrous ; sides deeply sinu- 

 ate near base, hind angles obtuse ; in female more convex, with a transverse 

 elevation near apex, disk with small, triangular, scale-like granules and

Monroe County; rare. June 9. A single female collected by 

 Max Ellis. Described from St. Louis, Missouri. After describing 

 this form as distinct, Dr. LeConte in 1863 placed it as a variety of 

 triangularis Say. In this he was followed by Blanchard. Chas. 

 W. Leng, to whom the specimen was sent for identification, takes 

 the ground that the original name torrens should be restored until 

 the relationship of the beetle to triangularis is settled.
