Eleodes (Melaneleodes) rileyi Casey, 1892

( Fig. 9A )

Diagnosis. 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.
