Brauer and Bergenstamm (1891) used the name S. aurifera 

 Maeq. but we suspect it to be an error for S. mirifrons. At 

 any rate it is a mere nomen nudum as used by these two authors. 



Walker (1849) added the names of four species to the list, 

 viz., (9) S. impatiens, (10) 8. misera. (11) S. irrequieta, and 

 (12) S. prcedafrix. The type specimens of all four species are 

 in the British Museum and are females labelled as having 

 been collected in Sydney, New Holland, Houtman's Abrolhos 

 (West Australia), and Port Essington (Northern Territory) 

 respectively. We are now able to give full accounts of the 

 first three of Walker's species, but the fourth is not represented 

 in our collection. 



Thomson in 1868 described two Sarcophagids collected 

 by the " Eugenie" naturalists in Sydney, viz., (13) S. ochri- 

 palpis and (14) S. pallichrus. The former was stated to be 

 near S. aurata, a species described by Macquart (locality, 

 ? Oceania) ; but we have regarded it as a synonym of S. irre- 

 quieta. S. pallichrus, Avhich Van der Wulp placed tentatively 

 in his genus Sarcophagula (1887), is not represented in our 

 collection. 



There do not appear to be any more references to the 

 group until 1891, when Olliff and Skuse named two parasites 

 of grasshoppers as (15) Tachina osdipoda and (16) Masicera 

 packyiili respectively. Olliff referred to the latter and pub- 

 lished a figure of it (1891a), the illustration being republished 

 by Mackinnon (1920). The species was subsequently stated by 

 Froggatt (1905, 1907) to be a Sarcophaga. Tachina oedipoda 

 is a nomen nudum as far as Olliff- (1891b) is concerned, but 

 Froggatt (1905, 1907) has reported it to be a Sarcophaga, 

 closely related to S. aurifrons. The status of these two flies 

 bred from locusts can only be determined by an examination 

 of the type material. 



Certain specimens collected in Brisbane and forwarded 

 by Mr. Froggatt (1907) to Coquillet for determination were 

 reported to be (17) S. frontalis. Owing to Mr. Froggatt's 

 kindness we have been able to synonymise Thomson's species 

 with Walker's S. misera. Besides, the name frontalis is pre- 

 occupied, having been employed by Doleschall in 1858. 



Information relating to S. aurifrons was published by 

 Mr. Froggatt in 1905, 1907, and in 1915.
