Special Publication #13

C. L. Staines

A key is presented to the 14 genera and 74 species and subspecies of hispines (Coleoptera: Chrysomelidae: Cassidinae) known to occur in America north of Mexico. Each genus and species is described and illustrated. The known larvae are described and the known biology is summarized. Baliosus ferrugineus from Arizona and Microrhopala inermis from British Columbia, Montana, and Oregon, are described as new. Sumitrosis arnetti Butte is synonymized with S. inaequalis (Weber); Microrhopala rubrolineata signaticollis LeConte, M. rubrolineata militaris Van Dyke, and M. rubrolineata vulnerata Horn are synonymized under M. rubrolineata (Mannerheim). The holotype of Platocthispa lateritia (Smith) has been located making the neotype designation of Staines (1997) invalid. Pentispa morio (Fabricius) is reported from the United States for the first time.
