248 NOTES ON AUSTRALIAN TABANIDAE, ii.. 



It is probable that the actual type of D. sub-appendiculata has been examined 

 by one of us (E.W.F.). In the Museum d'Histoire Naturelle, Paris, several 

 specimens of D. inflata were seen, labelled Pangonia fuscitarsis Macq. This 

 name, however, does not appear to have been published, and it seems possible 

 that the name may have been altered before publication and sub-appendiculata 

 inserted. The specimens were also labelled as from Tasmania and from the 

 Verreaux collection. The species, however, has not been met with by recent 

 collectors in Tasmania and is a common one in the coastal districts of New 

 South Wales, so that the locality has probably been wrongly given. 



DiATOMiNEURA viOLACEA Macquart. 



Pangonia violacea, Macquart, Dipt. Exot., Supp. 4, 1850, p. 22. 



These flies were very plentiful indeed on Palm Island, N.Q. in late Sep- 

 tember. Specimens were taken on the beach, on hillsides, in scrub-covered 

 ravines, on open grassy flats and in the dwellings. They were more sluggish 

 than most species of the family, keep near the ground, and show a decided pre- 

 ference for persons dressed in dark-coloured materials. 



Specimens of this species from the southern part of its range (New South 

 W]ales) are as a rule of a greenish-blue colour, while northern forms are more 

 purple. Both forms are to be taken in southern Queensland. The Magnetic 

 Island specimens are of interest in that their colouration corresponds with the 

 southern form. 



COEizONEURA CHRYSOPHILA Walker.

 Ann. Mag. Nat. Hist., (7), v., 1900, pp. 113, 120.— Pangonia aurofasciata,, Jaen- 

 nicke, Abh. Senck. Gesellsch., vi., 1868, p. 327, PI. 43, fig. 5; Ricardo, I.e., pp. 

 113, 120. — Pangonia nigrosignata, Thomson, Eugen. Resa., 1868, p. 541; Ricardo, 

 op. cit., (8), xvi., 1915, p. 36. — Pangonia rufovittata, Macq., Dipt. Exot., Supp. 

 4, 1850, p. 19. 



The above synonymy, with the exception of Pangonia rufovittata Macq., is 

 given on the authority of Miss Ricardo. This species was seen (E.W.F.) in the 

 Paris Museum among Ma.cquart's specimens of Tabanidae labelled Pangonia 

 rufovittata Macq., n.sp. Tasmania No. 529. The description of Pangonia rufo- 

 vittata also agrees with C. clirysophila Walk. The locality (Tasmania) given by 

 Macquart is probably wrong, other records appearing to be all from Sydney — 

 specimens are in the Australian and Macleay Museums from here. The species 

 seems to be now much rarer, as few captures appear to have been made of recent 

 years. There are, however, two specimens under examination, one taken at 

 Roseville in January, 1914, and one at Broadwater, Richmond River, during last 

 season (1920-21). 



We have retained the old generic title for this and allied Australian species, 

 though these species (at any rate chrysopMla and fulva) do not come under the 

 restricted generic diagnosis of Corizoneura given by Austen (Bull. Entomol. Re- 

 search, si., part 2, 1920, p. 139). At the same time, it hardly seems justifiable 

 to place them under the new genus Buplex. Probably extensive alterations in the 

 generic designations of Australian Pangoninae may be required owing to the re- 

 vival of Walker's sub-genera (Insect. Saund., Dipt. Part 1, 1850, pp. 7-11), and 

 until all our Australian forms can be examined and compared with species from 

 other parts of the world, it seems better to continue to employ, for the time 

 being, the well-known nomenclature of Rondani.
