 the preceding. Elytra elongate oval, with striae of punctures faintly marked, interstices 

 sparsely punctured and with slightly elevated rounded tubercles evident at least near the 

 apex. Propleurae with confluent reticulate punctures. Surface sub-opaque, faintly

Thorax similar to the preceding, with less rounded bind angles. The surface is 

 shining, not metallic. Elytra elongate oval, convex, faintly striate, interstices flat, very 

 sparsely punctured. Antennae slender, outer joints gradually decreasing, last joint oval, 

 not longer than the preceding. Propleurae finely wrinkled. Easily distinguishable from 

 the preceding species, the only one with which it might be confounded by description, by 

 its more convex form, shining surface and absence of any interstrial tubercles.

Abundant in the Middle States.
