from J.C. Ciegler:
"It certainly is a Pachybrachis. Pachybrachis dilatatus Suffrian and P. subfasciatus (LeConte) look very similar, with the same pattern of red spots and similar size. Both are smaller than the 5-6 mm estimated on your website, but none of our Pachybrachis species are that large. Because the pronotal punctures have depressions around each and are nearly as large as those on the elytra, and because the pronotum is rather shiny, I'm tending toward P. subfasciatus. My specimens of P. dilatatus have smaller pronotal punctures without any depression around each puncture, giving the pronotum a much flatter appearance, and the surface is not at all shiny. So I'm voting for P. subfasciatus."
