Very closely allied to the quercinus, Say, but the striae of the elytra are more 

 deeply impressed, and the punctures on the thorax more crowded than in that 

 species. The present species has the elytra subglabrous, and the feet reddish 

 piceous; in the quercinus, these latter organs are yellowish.
