One specimen, Pennsylvania. The thorax is longer lhan wide, very slightly narrowed 

 and not rounded from the l>asc to the middle, then narrowed and broadly rounded to tin- tip: 

 the elytra are slightly narrowed li< m the very base; the punctures of the interstici - are 

 close and distinct. Differs from the preceding by the third joint of the antenna? being 

 longer than the second, and by the form of the thorax : from the next by the much shorte r 

 pubescence and also by the form of the thorax.

Pennsylvania, rare. The thorax is a little wider lhan long, narrowed and round* d from 

 the very base; the punctuation is a little liner, and the pubescence considerably loi 

 than in the preceding species. The elytra are slightly narrowed from the very base. 

 The legs are rufo-testaceous, or ferruginous.

Pennsylvania and Vermont. The antennae are more slender than in the n< ighbouring 

 specie-; the thorax is considerably rounded on the sides, but the narrowing is Bcarcely 

 r> rceptible from the base to the middle; it is less convex than usual and not at all chan- 

 nelled posteriorly; the posterior angles in Dr. Melsheimer'a type continue the line of the 

 sides, while in my specimen they are Blightly divergent. The elytra are parallel to the 

 middle, very slightly narrower than the thorax; the stria are nol deep, the interstii 

 are not convex, finely and not densely rugosely punctured.

\ specimen found at Lake Superior ; another with paler legs brought from Maine by 

 Prof. Guyot. The thorax is a little longer than wide, narrowed and rounded before the 

 middle, with the sides parallel posteriorly. The elytra are parallel as far as the middle, 

 then obtusely rounded to the ape\ ; the Btrioe are narrow and well defined; the interatii 

 are not convex; the antenna) are strongly serrate, the third joint hardly longer than the 

 second : the eleventh joint oval.
