This species is related to T. rujiiiotuliis liigot. liut dift'ers in its broader- torju. 

 and broader forehead with larger secondary callus, spotted wings, and in its gen- 

 eral appearance. This species has been placed under T. pallipennis Mact)., though 

 it does not completely agree in all details; in Macquart's description there are 

 said to be three calli on the front, the lower two contiguous and sometimes united; 

 in the iireseut specimens there are only two calli, unless the dark area on the 

 vertex be regarded as a third callus, and the middle one is equidistant from the 

 vertex and the lower callus. The wing^ also ditt'er from the description; in /'. 

 pallipennis they are described as a little greyish, though the name pallipennis 

 would indicate a whitish winged species. Under a lens the wings appear as 

 described above, but in certain lights they appear decidedly jjale and the dark 

 spots around the cross-veins are not cdnspicuous. This pale appearance is more 

 marked in a female recently received from Lake Hattah, Victoria (Nov., 1919 — 

 J. E. Dixon) . It is possible that T. pallipennis Macq. is a distinct species, but 

 until specimens are available agreeing comjiletely with the description it seems 

 preferable to treat tliese specimens as belonging to Macquart's species. 



Tabanus duplonotatus Ric. 



Ricardo, Ann. Mag. Nat. Hist., (8), xiv., 1914, p. 39(i; T. pa n-i callus us, 

 Taylor (nee Ricardo), Proc. Linn. Soc. N.S. Wales, xlii., Pt. 3, 1917, p. 524; 

 ibid., Rec. Aust. Mus., xii.. No. 5, 1918, p. 64. 



This species has been wrongly identified by Taylor; we have specimens 

 compared with the types of both Miss Ricardo's species, and specimens identitied 

 by Tayhir and recorded above as 7'. pnrric((Iliisus agree with T. ilnpUniiitatua. 



Tabaxus iNxoT^VBiLis Walker. 



Walker, List Dipt. Brit. Mus., Part 1. 1848, p. 177; T. dorsobimaculutus 

 Macr]., Dipt. Exot., suppl. iv., 1850, y. JS; Ricardo, Ann. Mag. Nat. Hist., (8), 

 XV., 1915, p. 273; T. duplonotatns, Taylor {nee Ricardo), Proc. Linn. Soc. N.S. 

 Wales, xli., Pt. 4, 1916, p. 755. 



As the species identified by Taylor as 7'. duplonotatus Ric. did not at all cor- 

 respond with a specimen ccmipared with tlu' ty|ie (E.W.F.), specimens were 

 sent to London (G.F.H.) and have l)een identitied hy Dr. (J. A. K. Mai-shall 

 as '/'. innolahilis W;dker. 



Tahaxi's apbki'ks Tiiylor. 



Tayha-, Proc. Linn. S,ic. X.S. Wales, xliv.. I'l. 1. 1919. p. 5(i; 7'. hatchclori. 

 Taylor, loc. cit., p. 58. 



The types of the two siiecies have been very < aiefidly compared and we are 

 unable to maintain them as rlistinct; the i)rincipal dilference between them is 

 that T. hatchelori has the wings slightly clouded with brown along the veins, 

 whereas in T. aprepes the wing-s are practically- clear. A series from Burnett 

 River, however, shows con.siderable variation in the amount of suffusion, and varies 

 from sjiecimens in which the wings ai-e more stroimly mai'ked than in T.
