This work presents accounts and illustrations of the lady beetle species reported from Puerto Rico. Fifty-three species are discussed, including rare and uncommon lady beetles occurring on the Puerto Rican archipelago. The work also includes keys for subfamilies and species, the description of a new species ( Zilus barbosi sp. nov.), and a redescription of Diomus ochroderus (Mulsant). Brief accounts of the history of coccinellid collections and collectors, and of classical bio-control efforts in Puerto Rico are given, including an annotated list of 24 historical biological control introductions.
