Review of the New World Species of Hippodamia Dejean (Coleoptera: Coccinellidae)
By Edward A. Chapin
Smithsonian Miscellaneous Collection, vol. 106 no. 11, 1946
With 246 figures, this 1946 publication is still the visual reference for North American Hippodamia. (Gordon(1) and American Beetles both refer the reader to it for more comprehensive illustrations than their own publications provide.) Chapin examined thousands of specimens of each species, and illustrated the complete range of dorsal patterns for each. The male genitalia of each species is also illustrated.

Range maps, though limited, accurately depict type localities. Species names match modern taxonomy, but subspecies are outdated. The non-native species H.

With this key, I find it easier to identify the larvae of Cycloneda munda, C. polita, and C. sanguinea than the adults!
