NOTES ON THE BIOLOGY OF SOME 

 QUEENSLAND FLIES. 



By Professor T. Harvey Johnston, M.A., D.Sc, Hon. Zoologist, Queensland 

 Museum; and M. J. Bancroft, B.Sc, Walter and Eliza Hall Fellow in 

 Economic Biology, University, Brisbane.

During our experimental work with Diptera as possible transmitting 

 agents of certain worm parasites of horses and stoek^ we used a number of 

 species of flies found associated with these animals, some of them being either 

 insufficiently described or apparently undeseribed. We have already dealt 

 with a few of these flies (Johnston and Bancroft, 1919) and now propose to 

 give an account of certain others which, as far as available literature allows 

 us to judge, belong to undeseribed species of Musca.^ 



We desire to express our appreciation of the assistance given by Dr. E. W. 

 Ferguson, Health Department, Sydney; Mr. W. W, Froggatt, Government 

 Entomologist, Sydney; Dr. A, B. Walkom, Linnean Society, Sydney; and 

 Mr. W. A. Rainbow, Australian Museum, Sydney. Typical specimens have 

 been deposited in the Queensland Museum, Brisbane, and in the Australian 

 Museum, Sydnej'. 



MUSCA TERRaJ-REGINa: n. sp. 



(Text-figs. 1, 2, 9, 10, 1.5, 17, 18, 27, 28, 31, 37, 38, 41, 42, 43, 44, 45.) 

 This is a rather small fly about 4-5 mm. in length, which has been taken 

 occasionally on stock in the Eidsvold district and is referred to in our previous 

 paper (1919, p. 182) as Musca sp. indet.

Head (fig. 9). — One is struck with the relatively enormous size of the 

 eyes which occupy more than three quarters of the front of the head. They are 

 separated from one another by a narrow frontal stripe bounded by numerous
