182 MUSCA AUSTRALIS MACQ., M. VETUSTISSIMA WALKER. 
domestica is common in houses, but Fannia scalaris and 
F. canicularis have not yet been noticed, nor has Muscina 
stabulans, though the last two-named occur in Brisbane. 
Stomoxys calcitrans is decidedly scarce in the bush, but 
common in the vicinity of stables in certain outlying 
districts. Though there are plenty of suitable breeding 
places in Eidsvold, yet specimens of the species have not 
been noticed in the township Amongst blowflies one 
notes that Anastellorhina augur Fabr. (syn. Calliphora 
oceantae) is very common right through the year, while 
others which occur in the district are Neocalliphora ochracea, 
Pollenia stygia Fabr. (syn. Calliphora villosa), and the 
metallic blowflies Lucilia sericata, Calliphora incisuralis, 
Pycnosoma rufifacies and P. varipes. Belonging to the 
Anthomyide are Ophyra nigra; also a small black 
Fannia sp., very commonly seen on stock; and, in 
addition, a slightly larger slaty grey species (Fannta sp.) 
which is rather uncommon—both of these breeding in 
cowdung, while Oph. nigra is one of the “sheep 
maggot flies.’ There is also a rather small blowfly 
(Lasiopyrellia) of a bright metallic green colour (like that 
of a Pycnosoma) when alive, but changing to a fine cobalt 
blue in from one to two days after death. This species is 
rather broader and shorter than typical examples of 
M. australis. It deposits its eggs in cow manure. Also 
ovipositing in the same material is a very small blowfly 
(probably a Pseudopyrellia) resembling the Lasiopyrellia 
in colouration when alive, but when dead the blue is less 
intense and slightly greenish, and the wings more 
iridescent. This fly possesses habits similar to those of 
Pseudopyrellia australis mentioned by Cleland (1913, 
p. 566). Sarcophaga misera Walker is common, especially 
during summer. In addition to the above one might 
mention the presence of a Muscid, Musca sp. indet., which 
is rare in the locality and lays its eggs in horse dung.
