LATREILLE Hist. nat. d. Crust. et des Ins. Tom. xtv. Pl. 92, f. 14, and other 
larger species on foreign bats. According to Léon Durour there are only 
two simple eyes, Ann. des Sc. nat. Tom. Xxt. p. 374; in foreign species 
two simple eyes occur on each side. NirzscH has observed that these 
insects are true pupipare, like Hippobosca (SCHWEIGGER’S Jahrbuch der 
Chemie u. Physik, Bd. xvt. 1826, 4. 8. 436). Comp. on this genus J. O, 
Westwoop, Transact. of Zoolog. Soc. 1. 1835, 4t0, pp. 275—294. Pl. 36. 
All the species of this genus live on bats. 
Phalanx II. Hippoboscide (Coriacea LAtTR.) Head received in 
the emarginate thorax. Wings divaricate or incumbent, in some 
very small or none. Last joint of tarsus the longest of all. 
Braula Nrrzscu. Eyes and ocelli none. Wings none. 
Sp. Braula ceca Nirzscu, Grrmar Magaz. der Entom. 111. pp. 314, 315; 
AHRENS, Faun. Ins, Europ. Fase. vi. Tab. 25; Réaum. Mém. v. Pl. 38, 
figs. 1—4; this small insect lives parasitically on bees ; the metamorphosis 
is unknown. Is this its place ? 
Melophila Nrvzscu, Melophagus Larr. Eyes small, ocelli none. 
Wings and poisers none. 
Sp. Melophila ovina, Hippobosca ovina L., Friscu, Beschreib. von allerl. Ins.

f. d. gesammt. Thierheilk. 1843, 1X. Tab. 1, fig. 15. The sheep-louse is a 
wingless fly ; Rampour has given a description and figure of its digestive 
organs ; and Lyonner in his posthumous worksa careful and elaborate pic- 
ture of its structure, especially as concerns the external parts ; Recherches 
sur VAnatomie et les métamorph. &c. pp. I—27, Pl. t—3. There are two 
small oblong eyes ‘each consisting of a hundred round fagettes remote 
from each other, (groups of simple eyes ?) 
Sub-genus Lipoptena Nirzscu., (Spec. of Melophagus Latr., 
Marc.) differs from the preceding by very short rudiments of wings, 
by distinct poisers, by moderate eyes. 
Sp. Pediculus cervi L., Fasr., Panzer, Deutschl. Ins. Heft 51, Tab. 15. 
Ornithomyia Latr., Nirzscu. (Spec. of Hippobosca L., and 
Far.) Eyes distinct; ocelli usually three in vertex. Wings 
distinct. ‘Tarsi with tridentate claws. 
Sub-genera: Anapera Murtc. (Oxypterum Leacu.) Eyes none, 
wings short, acuminate. 
Stenopteryx Leacu, Mric. With three ocelli, wings very narrow, 
longer than the abdomen. 
Ornithonyia Luacu, Mric. With three ocelli, wings incumbent, 
obtuse.
