Females have the explanate elytral margin distinctly wider over the middle onethird, hence the sides of the elytra are arcuate for the entire length, not nearly parallelsided in front of the middle as in males. In females the elytra are slightly more transversely convex and the apices are conjointly rounded instead of distinctly separately rounded as in males. The labrum in females is emarginate, but not quite as deeply as in males, and the apical margin is not upturned. The pronotum is usually slightly more micropunctulate in females; sometimes, in males, the area bordering each side of the median groove is shiny and apparently nonmicropunctulate. Males have a conspicuous tuft of golden setae on the apical part of the last sternite, whereas females have sparse setae that do not form a tuft.
