ABSTRACT:
A taxonomic study of the Coccinellidae of Louisiana was undertaken in 1965 to identify the species occurring in the state. Keys and descriptions are provided for the 6 subfamilies, 11 tribes, 27 genera, and
71 species recorded as occurring in the state. Of the species listed, 38 are reported as new. Distribution records by parish and dates of seasonal occurrences are given.
