70 PROCEEDINGS CF THE ROYAL SOCIETY OF QUEENSLAND. 



Abdomen oval ; genital segments are not visible from 

 above. First ventral plate short but wide, second longer but 

 narrower and bearing ten bristles, third still narrower with four 

 bristles, fourth very narrow, fifth and .sixth very narrow and 

 fused. 



Our specimens were bred from bad meat in Brisbane and 

 horsedung in Eidsvold. 



This species was first described by Walker (1849, p. 829), 

 the type in the British Museum being a female from " New 

 Holland. '' That institution also has specimens sent by Dr. 

 Bancroft from the Burnett River. Mr. E. E. Austen, of the 

 British Mu.seum, has identified for us. by comparison with 

 Walker's type, some females which are co-specific with other 

 females common in Brisbane, Avhile males have been obtained 

 by breeding. 



Mr. W. W. Froggatt, of Sydney, has kindly allowed us to 

 examine a specimen collected at North Pine, near Brisbane, 

 originally determined for him by Coquillet as S. frontalis,^ and 

 referred to by him under this name (Froggatt, 1907, p. 315). 

 It has been found specifically identical with S. misera. John- 

 ston and Bancroft (1920, p. 75) have alread}^ referred to the 

 presence of this species (Burnett River and Brisbane), while 

 Oeland (1912, p. 150 ; 1913, p. 567) reported its occurrence 

 in Sydney and Adelaide. Walker in his original description 

 mentioned its presence in West Australia. Mr. Trj^on (1917, 

 p. 53) has referred to S. fronlalis as one of the Queensland sheep 

 maggot-flies. It seems to occur, then, over the whole of 

 Australia.

S. frontalis (in part) Froggatt 1907. 

 ;S'. subtubp.rosa Parker 1917. 

 Among the male Sarcophagas captured around carrion in 

 Brisbane are a few which are in every way identical "with the 

 males of S. misera except for small differences in the structure 

 of the penis. In these forms the anteriorly projecting bifur- 

 cated chitinous bars at the termination of the organ are con- 

 siderabh^ shorter and stouter, whereas the chitinous mass 

 above these is much weaker, and even foliaceous in appearance 



1 Thomson's specific name was already preoccupied, S. frontalis 

 having been given to a fly from Amboina by Doleschall in 1858.
