Hyperalonia cingulata, v. d. Wulp. * 



Exoprosopa cingulata, v. d. Wulp, Notes Leyden Mus., vii., 

 1885, p. 62. 



Hab. — The species was described from Adelaide. In the 

 Macleay Museum there is one specimen from South Austra- 

 lia, one from Port Denison, and one from Darling River. 



Genus Exoprosopa, Macquart. 

 Exoprosopa, Macquart, Dipt. Exot., ii. (1), 1840, p. 35. Id., 

 White, Proc. Roy. Soc. Tasm., 1916, p. 205. 

 Note. — Four names are placed under this genus, and 

 two of these belong to recognised species. The other two 

 names apparently belong to distinct species which are not 

 represented in the collections examined. 



Exoprosopa laterimhata. Bigot. 



Exoprosopa laterimhata. Bigot, Ann. Ent. Soc. France (7), 

 Ixi., 1892, p. 346. 



Note. — The third segment of the abdomen has a white 

 lateral fascia, which reaches almost to the median line. The 

 species was described from a specimen with incomplete 

 antennae and denuded abdomen. 



Hab. — Five specimens in the Macleay Museum are 

 identified as belonging to Bigot's species, and are labelled 

 from: — Western Australia; Queensland, including Port 

 Denison and Rockhampton; and New South Wales. 



Exoprosopa stellifer, Walker. 



Anthrax stellifer. Walker, List Dipt. B.M., ii., 1849, p. 244. 

 Litorhynchus stellifer, Walker, Ins. Saund. Dipt., 1852, 

 p. 166. 



Variations. — Two specimens of a series agree with 

 Walker's description too well to be mistaken, but the re- 

 mainder have the hyaline area of the wings varying from a 

 narrow strip to a triangular area which reaches from the 

 hind border to a point slightly beyond half the length and 

 nearly across the discal cell. The basal half of the abdomen 

 is sometimes brown with a black median stripe, and the 

 white abdominal fascia may form a band almost reaching 

 across the abdomen or may be obsolete. 



Hab. — Western Australia. In the Queensland Museum 

 there is a specimen labelled "Cunderdin." South Australia: 

 there are eight specimens in the Macleay Museum from this 

 State.
