Of the 15 Mexican forms included in Coccinella L. by recent authors, nine do not belong to that genus, and the records of four others may be erroneous. A key to six forms that may or do occur in Mexico is given. The two forms that surely occur there, nugatoria Mulsant 1850 and sonorica Casey 1908, are considered only subspecifically distinct from one another. No new names are proposed.
