264 NOTES ON AUSTRALIAN TABANIDAE, ii., 



four miles of£ one of the Vernon Group of Islands and were afterwards cap- 

 tured at intervals until a landing was made on Melville Island. Several of the 

 above species, as well as two examples of Silvius indistinctus Ricardo, were 

 captured at a distance of not less than 10 miles from the nearest land (Melville 

 Island), and upon going ashore at about 6 p.m., both species were found to be 

 fairly plentiful, but far less so than T. cinerascens King and T. neogermanicus 

 Ricardo. 



Tabanus eivularis, nov. nom. 



Tahcmus pygmaeus, Ferg. and Henry, Proc. Linn. Soc. N.S. Wales, xliv., 

 1919 (1920), p. 842, PI. xliv., Fig. 2 (nee T. pygmaeus WjUiston, 1887). 



A change of name is necessary, as T: pygmaeus has been already used by 

 Williston for a North American species (Trans. Kansas Acad. Sc, Vol. 10, 1887, 

 p. 141). 



The present name is suggested by the habits of the adult insect. The ori- 

 ginal specimens came from Camden Haven; since then the species has been dis- 

 covered at Eceleston on the AUyn River, a branch of the Patterson, on the north 

 side of the Hunter River Valley. The species was found confined to the banks 

 of th* stream and attacking the heads of swimmers in the river (March, 1921). 



Tabanus moretonensis, nov. nom. 



T. eonfustts, Taylor, Proc. Linn. Soc. N.S. Wales, xlii., 1917, p. 523 inom. 

 praeocc). 



The type of T. confusus Taylor in the Queensland Museum was examined 

 (E.W.F.) recently, and found to be incoiTectly placed in Miss Rieardo's Group 

 iv. of the genus. The eyes are hairy, which places the species in Group xi. 

 (Therioplectes), while the frontal callus is not absent, but is transverse, occupy- 

 ing the whole front and little prominent; owing to abrasion it would appear at 

 first sight as if the callus were absent. The species belongs to the difficult 

 circumdatus-edentulus group, but appears to be distinct. 



A change of name is necessary as T. confusus has already been employed by 

 Walker (List Dipt. Brit. Mus., i., 1848, p. 147) for a species from North 

 America. 



Tabanus cirrus Ricardo. 



Ricardo, Ann. Mag. Nat. Hist., (8), xix., 1917, p. 222.-7. rohustus, Taylor, 

 Proc. Linn. Soc. N.S.W., xliv., 1919, p. 69. 



A specimen from Palm Island, N.Q. (26.9.20) has been compared with 

 Taylor's type by Mr. H. Hacker, and afterwards with Rieardo's type by Dr. G. 

 A. K. Marshall. 



Tabanus neolatifeons, nov. nom. 



Tahanus Mifrons, Ferg., Proc. Roy. Soc. Victoria, xxxiii., 1920 (1921), 

 p. 19, PI. ii.. Fig. 1 (nee T. latifrons Zetterstedt, 1842). 



The previous use of the name T. latifrons Zetterstedt (Dipt. Scand., Vol. i., 

 1842, p. 106) was quite overlooked in describing the Australian species. Zetter- 

 stedt's name is a synonym of T. cordiger Meigen (Syst. Beschr., Vol. 2, 1820, p. 

 47) from the Mediterranean region. 



Tabanus adelaidae, nov. nom. 



Tahanus meridionalis, Ferg., Records South Aust. Mus., Vol. 1, No. 4, 1921, 

 p. 376 (nee T. meridionalis Thunberg, Nova Arta Upsal., Vol. 9, 1827, p. 58).
