THE BIPTERA-BRACHYCERA OF TASMANIA. Part I. Families Lei-tid.e, Stratiomyid.e, Nemestrimdje^ & Cyrtid.e. By Arthur White. (Received 7th July, 1914. Read 13th July, 1914. Issued separately 10th September, 1914.) The preseut paper is intended to form the first parr, of s-general revision of the Diptera-Brachycera of Tasuiania^r The families Leptidce, Stratiomyidce, Nemestrinidcs, and Cyriidce are dealt with : the Tahanidce, which should properly V)e taken between the SiratiomyidcB and Neinestrinidce, are^ held over for the present for the purpose of further study. I wish to take this opportunity of acknowledging my indebtedness to Mr. W. W. Froggatt, Government Eiitomolo--gist of New South Wales, Mr. G. B. Hardy of the Tasmanians Museum, Mr. A. M. Lea of the Adelaide Museum, Mr. F. M. Littler of Launceston, and, particularly, Mr. F. P. Spry, of the National Museum, Melbourne, who have been most kind in looking up references for me in works to which I had no access, or in supplying me with specimens for examination. Most of the Tasmaniau species of Diptera that lia,ve been named up to the present lime, 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 t>y 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 Cordyhirid(f, by Osten-Sacken {Ent. Monthly May., 1881), and a species ot Hi2)poboscidce by Wesche (Ann. Mag. Nat^ Hist., 1903). Finally some new species of Asilidce 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 dealiug more particu-larly with the Diptera of the mainland States, especially Skuse, "■ Diptera of Australia" {Proc. Littit. Soc, N.S.W.^ 1888-90), which deals with the Diptera-Nemocera; Ricardo, "A Revision of the Asilidae of Australia" (Atm. Mag. Nat. Hist., 1912-13); and Von Krober, " Thereviden des Indo-Australischen Region" {Entomologische Mitteihmgen, 1912-13).
