534 PROCEEDINGS OF SECTION D. 
Westw., each contains only a single described example. Oncodes, 
Latr., of world-wide distribution, has five Australian representa- 
tives ; while Prerodontia, Gray, and FPanops, Latr., have each 
three species (see Trans. Ent. Soc., Lond., 1876, pp. 507-518). 
The genus Ozcodes occurs all over the country; Thomson’s 
species described (Zugenzes Resa, 1868, p. 475) under the name 
of Mesophysa, from Sydney, belongs to Ozcodes. 
Fam. 27. Empip2. 
This family, so numerously represented in Europe and America, 
seems to be only sparingly so in Australia; the cosmopolitan 
genera, /Zybos, Hilara, and Hmfpis, Meig., are indicated by one, 
two, and three species respectively. The two species of Alara 
belong to Tasmania; Lmpzs occurs in New South Wales and 
Tasmania ; the single species of Ay4os is only known in New 
South Wales. There are some undescribed species known to me 
in collections. 
Fam. 28. DoLicHoPpoDID™s. 
The Dolichopodide seem numerous in both genera and species, 
but only twenty-one species have been described; all but one 
have been characterised under the generic title Psz/opus, Meig. ; 
the odd one is a Hydrophorus, from Tasmania. Doubtless many of 
those described by Walker and others as Psz/opus will eventually 
be found to really belong to different genera; some names, I 
believe to be synonyms. Loew (Mon. Dipt., N. Amer. IT., 1864) 
has written an important work on the North American species. 
Fam. 29. LoNCHOPTERIDE. 
No species have yet been recorded, though the family, which is 
throughout the world represented by only a single known genus, 
occurs in Australia. 
Srotion II.—DIPTERA CYCLORHAPHA. 
Division I.—PrRoposcipEA. 
Except among the Syrphide, Tachinidae, Dexide, Muscide, 
and Anthomyide, very little is known of the Australian species 
belonging to the numerous families included in this division. 
The Cordyluride, Lonchxide, Heteroneuride, Sepsidz, Diopside, 
and Asteide are unknown. 
Fam. 30. SyrRpPHIDZ. 
Twenty-three genera of this extensive family are known in 
this country; the widely-scattered genera Syrphus, Fab., and
