Catalog of Forms Described as New By M. A. Carriker, Jr. THIS CATALOG PRESENTS a Complete list of all new families, subfamilies, genera, subgenera, species, and subspecies of Mallophaga described and published by the author from 1902 to 1967, inclusive. All original citations have been given, with corrections of those hosts that were originally erroneous, as well as corrections in the nomenclature of both hosts and parasites. The present status, as given for the various categories, has been derived in part from subsequent research by the author, as well as from the publica-tions of others, but where the author's opinion has not been in conformity with that of other workers in the group, his own opinion has been followed in giving the present status of genera, species, and subspecies. In many cases the nomenclature given in the Catalogue of Mallophaga by Hopkins and Clay, 1952, has not been followed, especially in the matter of bi-nomials and trinomials and synonymy. All types listed in this catalog, unless specifically indicated otherwise, are presently in the collection of the U.S. National Museum. The author wishes it understood that in his work he has designated as "paratypes" only the specimens taken on the same individual host with the "types," a procedure not followed by all workers in this group of insects. I am greatly indebted to Dr. J. F. Gates Clarke, Chairman, Department of Etomology, U.S. National Museum, and Dr. K. C. Emerson (especially the latter), for their many helpful suggestions, corrections, and additions during the preparation of the manuscript, and to the Smithsonian In-stitution for the continued assistance it has given me in my studies of this most interesting group of insects.
