The Diptera-brachycera of Tasmania. Part I. Families Leptidae, Stratiomyidae, Nemestrinidae and Cyrtidae.

The present paper is intended to form the first part, of a general revision of the Diptera-Brachycera of Tasmania.
The families Leptidae, Stratiomyidae, Nemestrinidae, and Cyrtidae are dealt with : the Tabanidae, which should properly be taken between the Stratiomyidae and Nemestrinidae, are held over for the present for the purpose of further study.
Most of the Tasmaniau species of Diptera that have been named up to the present time, were described about the middle of last century by Macquart (Dipteres Exotiques, 1838-55) and Walker (List Diptera Brit. Mus., 1848-55; Insecta Saundersiana, Diptera, 1850; and Trans. Ent. Soc .
Lond., 1856-8). A few species were also described by Erichson {Archiv f. Naturgesch , 1842). In later years a few species were described by Bigot ("Dipteres nouveaux ou peu connus," Ann. Soc. Ent. Fr., 1892) ; a single species of Cordyluridae by Osten-Sacken (Ent. Monthly May., 1881), and a species of Hippoboscidae by Wesche (Ann. Mag. Nat.
Hist., 1903). Finally some new species of Asilidae were described by myself in these Papers and Proceedings for 1913.
Various references to Tasmanian species previously described may also be found in various papers dealing more particularly with the Diptera of the mainland States, especially Skuse, " Diptera of Australia" (Proc. Linn. Soc, N.S.W. 1888-90), which deals with the Diptera-Nemocera; Ricardo, "A Revision of the Asilidae of Australia" (Ann. Mag. Nat.
Hist., 1912-13); and Von Krober, " Thereviden des Indo- Australischen Region" (Entomologische Mitteilungen, 1912- 13).
