Body elongate-ovate, rather parallelsided. Pronotum subquadrate, slightly arcuate laterally, widest just anterior of middle, disc moderately and evenly punctate. Elytra punctate-striate with punctures becoming scabrous to slightly tuberculate laterally and posteriorly on disc. Profemora unarmed, clavate. Prosternum flat, slightly projected posteriorly of procoxae. Distribution. Coconino and Apache Counties, Arizona . Widely distributed from Minnesota west to California and north to Montana . Remarks. This species is most similar to E. carbonarius and can be distinguished from the latter by the scrabrous punctures of the elytra. It also resembles E. halli , which can be separated from the present species by the elytra bearing small though well-formed tubercles each with a single, black seta.
