PROC. ENT. SOC. WASH., VOL. 60, NO. 4, AUGUST, 1958 167 ON A SMAIili COLLECTION OF MALLOPHAGA FROM THE UNITED STATES, WITH DESCRIPTIONS OF THREE NEW SPECIES By M. A. Carriker, Jr., Popayari, Colombia, S. A. The species listed in this paper were sent to the author for identifi-cation by Mr. Nixon Wilson, Department of Entomology, Purdue University, and were, when not otherwise indicated, collected by him. The collection contains nine species, three of which are apparently new" to science and are described below, while a fourth is probably a new subspecies, but lack of the necessary comparative material pre-vents its proper description. All measurements are in millimeters and all drawings were pre-pared b}^ the author, accurately drawn by means of the eyepiece micrometer. All types have been returned to Mr. Wilson, but paratypes, when available, have been retained by the author. Philopterus ocellatus (Scopoli), 1763 Pediculus ocellatus Scopoli, Eiit. Caniiolica, p. 382 (Host: Corvus corone {sar-doniiis Kleinsclimidt). The species of Philopterus found on the American Crow (Corvus hrachyrhynchos) has been determined to be the same as that of the European Crow (C. corone)^ according to Hopkins and Clay (Check-list of Mallophaga, 1952). I have not personally compared the Ameri-can parasite with authentic specimens of ocellatus. A pair of this species was taken on Corvus hrachyrhynchos by S. R. Joseph at Jacobus, York Co., Pa., Nov. 12, 1955. They agree with specimens in my own collection from Pennsylvania and Nebraska. Philopterus sp. A pair of this genus from Eremophila alpestris, collected by R. E. Mumford, Washington Co., Ind., Jan. 10, 1955. They are closely related to P. c. citrinellae (Schrank) (= P. com-munis of authors, in partim) , and are very likely subspecies of it, but I lack the necessary material for comparison. Bruelia rotundata (Osl)oin), 1896 Nirmtos rotundatus, Osborn, Bull. U. S. Bur. Eiit. (n.s.) 5: p. 226 (Host: Corvus corone hrachyrhynchos Brehm). A pair was taken on the same individual host as noted under Phil-opterus ocellatus. The specimens agree perfectly with material from the type host collected by the author at Lincoln, Nebraska.
