feebly elongate gibbosity on each elytron, usually with a row of small, rounded
granules along the crest, .'I few small granules on disk near scutellum, remainder of
basal fourth with numerous coarse, deep punctures which become slightly less coarse
apically, and laterally behind humeri fOfm rugosities to behind middle; humeri
