Lake Superior, one female. Broader and more convex than any other species 

 of this division, and approaching in its form the broader varieties of A. basil- 

 laris.

Lake Superior, Vermont, and. according to the authors above quoted, also 

 found in Russian America ; also in Kamschatkha and Northern Europe.

Lake Superior, one pair; a female from Massachusetts, sent by Dr. Harris : 

 the female from Lake Superior has impunctured striae, but does not otherwise 

 differ. Readily distinguished from the next by the longer thorax which is not 

 flattened on the sides, and by the interstices of the elytra being entirely flat 

 and even.

Lake Superior, Massachusetts, Pennsylvania and Illinois. Should this be 

 really Dejean's species, (and I place it as such on the authority of a specimen 

 kindly communicated by Dr. Harris.) it is very remarkable that neither he nor 

 any of the other authors quoted mention the dull sericeous appearance of the 

 upper surface.

 thorace latitudine duplo breviore, antrorsum subangustato, lateribus totundafis

New Mexico, collected by the late R. W. Kern. Also closely related to the 

 preceding, but the thorax is still shorter, less narrowed in front, with the ante-
