Missouri, Wisconsin. Dr. Engleman. Varies with the thorax rufo-testaceous, the 
pleurae of the thorax are thickly punctured. 
11. A. THORACICUS. 
Pachyla thoracica, Hald. 60. 
Differs from A. varians by its densely pubescent thorax. Not having a specimen 
I am unable to point out any other character. It was found in Pennsylvania, and is in 
Dr. Melsheimer’s Cabinet.

scabro, antennisque extrorsum fuscis. Long. -27. 
Cattaraugus County, New York. Mr. Haldeman. 
This species has the same form as A. varians, but is smaller, with a less convex 
thorax, the lateral angles are obtuse, but not rounded, and the margin of the elytra is 
much wider. 
Species mihi ignota.

are not diverging.
