Vol. 8, No.3· 4, September· December, 1994 213 A revision of the genus An;sostena weise (Coleoptera. Chrysomelidae, Hispinae). Part III. The pilatei species group C. L. Staines 3302 Decker Place Edgewater, Maryland 21037 U.S.A. Abstract The pilatei species group ofAnisostena s. str. is revised. Lectotoypes are designated for A. nunenmacheri, A. pilatei, and A. trilineata, A. mitchelli is synonymized with A. al izonica, A. cOlt/usa and A. vittata are described as new. Key words: Anisostena, lectotype, revision, new species. Introduction 2.
