Show 322 INSECTA. HIPPOBOSOA, proper. Fut•nished with wings; very distinct eyes occupying all the sides of the head; antennre in the form of tubercles, with three setre on the back. H. equina, L.; De Geer, Insect., VI, xvi, 1-20. Brown mixed with yellowish. Found on Horses and Oxen, usually under their tail and near the anus( 1 ). 0RNITHOMYIA, Lat. Only differing from Hippobosca in the antennre which project, are Iaminifo1·m and pilose; and in the -wings which are furnished posteriorly with strongly marked longitudinal nervures that extend to the posterior margin. These Insects, in the Monograph of the Diptera published by Dr Leach, form four genera. 1. FERONIA-Nirmomyia, Nitzschdistinguished from the following ones by the tubercular form of the antennre, and by the nails of the tarsi having but two teeth in lieu of three. 2. 0RNITHOMYIA, in which, ~sin the three following subgenera, there are ocelli and tridentated nails, and, as in the two which succeed, 1aminiform antennre, but where the wings are almost equally wide and rounded. 3. STENEPTERYX, similar to Feronia, with the exception of the wings which are narrow and very acute. 4. OxYPTERUM, where the wings are equally acute; but the antennre are dentiform, the eyes are small, and the ocelli are wanting as in Hippobosca and Feronia. They live on various birds, such as the Swallows, Titmouse, and even on the Vulture. 0. verte; Hippobosca avicularia, L.; De Geer, Insect., VI, xvi, 21-24. Green; top of the thorax black; proboscis pro· jecting; wings almost oval. On the Sparrow, 8cc.(2) · (1) See Lat., Gen. Crust. et Insect., IV, p. 362; Leach, Dufour, &c. (2) I.at., Ibid.; Encyc. Method., article Ornithomyie, Leach. The eyes of the Ornithomyi~e appear to me to be somewhat smaller than in Hippobosca. The sides of the thorax terminate anteriorly in a point. The sucker originates from a little piece emarginated like a heart, which~~ not exposed in Hippobosca.
