42 MEMOIRS OF THE QUEENSLAND MUSEUM. 



(Musca of authors). It differs, however, in several important points, viz. — (1) 

 the larva is carried in the uterus to the second stage, not the third; (2) eopula- 

 tory vesicles are present in addition to the accessory glands in the female. In 

 regard to (1) we might point out that the two posterior spiracular slits of this 

 instar are not straight but sinuous as they are in those of the third instar where 

 there are three.. Then again in the type species of the genus M. hezzii Patton, 

 "a larva is deposited, though in which stage mention is not made by Patton and 

 Cragg (1913, p. 23). In M. fcrgusoni the larva is deposited while in an eggshell 

 which at once bursts liberating it. 



This fly appears to be very hairy on account of the presence of well- 

 developed macrochgetfe on the dorsal part of the thorax. Many of the scutellar 

 bristles are very strong and are practically macrochietffi. The arrangement is 

 shoM'U in fig. 13. The vertical pairs between the eyes are strong. The ocellar 

 bristles are weakly developed in both sexes, especially in the male where they 

 are practically absent. 



The form of the tarsi and claws of the third leg in the two sexes is shown 

 in figs. 21 and 22. The palps bear very strong setas in both sexes, especially in 

 the male (figs. 33, 34). 



OTHER FLIES. 



In our earlier paper (1919, p. 182) we referred to the presence of certain 

 other flies in the Eidsvold district. The cobalt-blue species therein indicated as 

 Lasiopyrellia is a Pseudopyr cilia, according to Williston's Key to the North 

 American genera (1908), while the very small fly which was regarded as being 

 probably a Pseudopyr cilia, falls within the genus PyrelUa. It was mentioned 

 that both of these metallic flies frequented cowdung for oviposition. So also 

 does a rather handsome large blowfly which Mr. W. W. Proggatt has identified 

 for us as Stenopterina gigas Macq. A tiny species of Sepsis is very commonly- 

 found frequenting similar material and breeds in it. Patton and Cragg (1913&, 

 p. 310) refer to its presence in India. 



Muscina stahulans has been bred out of rotting potatoes received at 

 Eidsvold from elsewhere and no doubt the fly is occasionally to be met with 

 in the township. 



Amongst the Anthomyida occurring there one might mention that 

 Phaonia personata Walker, which at fivst sight somewhat resembles a large 

 greyish or bluish long-winged house-fly, is to be found in the vicinity of rotting 

 fruit and has been bred out from that material.^ Mr. Froggatt (1907, p. 311) 

 who kindly identified the species and also the one next mentioned, informed us 

 that it occurred conunonly in fruit-shops in Sydney. Sapromyza fuscicornis 

 Macq., a fairly large fly (Sapromyzid^e) with a striped thorax and a dark head, 

 has been bred from horsedung (Eidsvold).
