The genus is diagnosed and compared to both related and superficially similar taxa. Pseiidadonia Timberlake is recognized as a junior synonym (n. syn.). The species composition of the fauna is delineated, but the need to re-examine species limits and nomenclatoral priorities is stressed. New synonyms are proposed for two species of Cycloneda occurring in North America: Coccinella krikkeni lablokoff-Khnzorian, reported from India, and Cycloneda atra Casey (of unknown origin) are new junior synonyms of Cycloneda munda (Say); Cycloneda hondurasica Casey (Honduras) and Coccinella reflexa Germain (Chile) are new junior synonyms of Cycloneda sangui-nea (Linnaeus). Adalia galapagoensis Van Dyke is transferred to the genus Cycloneda (Cycloneda galapagoensis, n. comb.) and identified as a close relative of Cycloneda sanguinea. Cycloneda sanguinea cayniana Chapin is elevated to full species status {Cy-cloneda caymana, n. status). A new key to species of North American Cycloneda is provided.

In with a white border design and pair of dis-Central and South America (Blackwelder cal spots (Fig. 9). The basic components of 1945), the genus is a composite one, com-the white design are often coalesced to form prising an assemblage of two dozen or more a complete or broken ring in each lateral species which generally share a rounded third (Figs. 2, 5), and a median spur shaped convex body form, highly polished cuticle, mark is often present at anterior border and little else. In contrast, the three North (Figs. 2, 5, 8). America indigenes — Cycloneda sanguinea The North American Cycloneda were (L.)
