Monocesta coryli (Say) is rather widespread in the eastern United States. In life, the beetles are usually bright yellow with the basal and apical thirds of the elytra metallic blue. In pinned specimens, the yellow areas fade to pale tan. A number of years ago (Clark, 1986), I reported on an unusual color form that occurs in southern Ohio, the dark elytral markings being either entirely absent or very poorly developed. More recently (Clark, 2000), I stated that both forms occur in West Virginia, but I gave very little information regarding the distribution of each.
