601 NOTES ON AUSTRALIAN DIPTERA WITH DESCRIPTIONS. By J. R. Malloch. {Communicated by E. W. Ferguson, M.B., Ch.M.) [Read 28th November, 1923.] Family MUSCARIDAE. In this paper I give some notes on species whicli have usually been jDlaeed in the family Anthomyiidae. After a very careful investigation of a great mass of material from all parts of the world I have been forced to conclude that there is no line of demarcation between these so-called families, and consider that stressing a point or two merely to conserve the existing alignment in our cata-logues is not the proper method of procedure to adopt. Stein in his most recent papers included the Muscidae as part of the family Anthomyiidae, but the former, being the oldest name for the complex, must be used in preference to the latter. All the genera which I deal with in this paper belong" to the group which has the first posterior cell of the wing not or but little narrowed at apex, the fourth vein being but slightly or not at all curved forward apically and never angularly bent some distance from its apex. Most of the species were submitted to me by Dr. Eustace W. Ferguson, to whom the types will be returned, but some are from a lot sent to Dr. Aldrieh of the United States National Museum by Dr. J. Illingworth, and are placed in the institution which received them. Subfamily PHAONIINAE. MusciNA STABULANS Fallen. A very widely distributed species, occurring in Europe and America. I have before me two males from Blackheath, and Blue Mountains, N.S.W. The flies often occur indoor and around houses. I have reared the species from decaying mushrooms in North America. Anaclysta Stein. This genus was erected by Stein in 1919. The name had been previously used by Brauer and von Bergenstamm, but their genus was based upon an un-described species and their description was erroneous, so that he rightly refused to credit it to them. Stein himself included flavescens Stein, a species which does not belong to Anaclysta but to EulimnopJiora. I now designate as genotype of Anaclysta, the species multipunctata Stein. The principal characters of Anaclysta are enumerated below.
