58 AUSTRALIAN BOMBYLIID.E AND CYRTID.E (DIPTKRA), 



Comptosia fasciata, Hutton, New Zealand Dipt., 1881, p. 24. 

 Neiiria nigricens, Newman, Entom., i., 1841, p. 221. 



Synonymy. — Anthrax fasciatus, Fabricius, is described 

 from the Pacific Islands. Walker refers N. nigricens, New- 

 man, to the same name, and gives New Holland for locality. 

 Schiner uses the name for specimens from New Zealand. 



N. nigricens, Newman, is from near Sydney, and un- 

 doubtedly is the same as specimens identified here as C. fas- 

 ciata, Fabricius. 



Note. — The species is similar to C. lateralis, Newman, 

 C. albofasciata, Thomson, and C. apicalis, Macquart. It 

 differs from the last of these by the white spot of the wing 

 being subapical instead of apical, and from the other two by 

 the abdomen being not red laterally, 



Comptosia lateralis, Newman 

 Neuria lateralis, Newman, Entom., i., 1841, p. 220. Id., 

 Walker, Ins. Saund. Dipt., 1852, p. 167. Id., Schiner, 

 Reise Novara, 1868, p. 131. 



Anthrax insignis. Walker, List Dipt. B.M., ii., 1849, p. 266. 



Synonymy. — Walker evidently changed the name of this 

 species to Anthrax insignis, as Anthrax lateralis was pre- 

 occupied by Say in 1823; the species, however, belongs to the 

 genus Comptosia, and in any case it cannot belong to the 

 genus Anthrax. 



White identified a specimen in Dr. Ferguson's collection 

 as C. fascipennis, Macquart, which spacies is queried from 

 Monte Video. 



Note. — This species diff'ers from the previous by the 

 abdomen being bordered laterally with large separated, al- 

 most confluent reddish spots, and from the next species, 

 C. albofasciata, Thomson, by the smaller size. 



Comptosia albofasciata, Thomson. 

 Comptosia albofasciata, Thomson, Eugenies Resa, 1868, 

 p. 484. Id., Froggatt, Austr. Ins., 1907, p. 296, 

 PL xxviii., fig. 5. 

 Note. — It is possible that this species is only a large 

 form of C. lateralis, Newman. 



Comptosia ducens. Walker. 

 Anthrax ducens, Walker, Ins. Saund. Dipt., 1850, p. 176. 

 Neuria dncens. Walker, ibidem, p. 167.
