Vol. 8, No.1· 2, March· June, 1994 125 A revision of the genus Anisostena weise (Coleoptera. Chrysomelidae, Hispinae). Part II. The subgenus Anisostena: Key to the species groups and the ariadne species group. C. L. Staines 3302 Decker Place Edgewater, Maryland 21037 Abstract The subgenus Anisostena (Anisostena) is divided into three species groups. A key to the species groups is provided and the ariadne species group is revised. Lectotypes are designated for A. ariadne, A. bellula, and A. elegantula. Key words: Anisostena, lectotype, species group Introduction Description: Head: last five antennal segments This is the secondin a series ofarticles revising WIder than precedmg; sulcus on mner margm of the genus Anisostena. The first artiCle (Staines, each eye; row ofpunctures on outer margin ofeaeh 1993) summarized the work on the genus and eye. Pronotum: basal margin bisinuate.

Elytrallength was measured from the base to apex along the suture. Total length was I.
