Notes on Some of Osborn's Mallophaga Types and the Description of a New Genus, Rotundiceps (Philopteridae)

There is a small series of Herbert Osborn's Mallophaga types, comprising nine species, in the Museum of Comparative Zoology. These were described as new in his 1896 paper, Insects Af fect in ,g Domestic animal^.^ I should like to express my indebtedness to the late Mr. James E. Peters, Curator of Birds, Museum of Comparative Zoology, who permitted me on numerous occasions to examine bird skins for lice to help determine the validity of host designations, and to Dr. Joseph Bequaert, Curator of Insects, for the loan of the type material. Mr. Louis Lipovsky, Department of Entomology, University of Kansas, supplied me with additional material. Dr. K. C. Emerson has given me many valuable suggestions concerning the material. A grantin-aid from the Society of the Sigma Xi made i t possible for me to complete this study.
