 Tabanus fai/lori, Austen, Ann. & Mag. Nat. Hist. (8) xiii. p. 265 (1914). 



Type (female) from Australia aud another female from 

 Sydney^ The paratype of Tabanus fuscipes, given to the 

 Brit. Mus. Coll. by the author, and renamed Tabanus taylori 

 by ]Mr. Austen, the name fuscipes being preoccupied, on 

 comparison with Bigot's type is identical, though it is 

 described as from Queensland. 



Tabanus posticus, Wied., Ausszweifl. Ins. i. p. 152 (18.28), 

 is possibly identical with this species, but it is impossible to 

 speak with certainty without seeiug AYiedemann's type. 



Tabanus serus. Walker, Proc. Linn, Soc. vi. p. 20 (1862), 

 from New Guinea, is nearly allied, but the forehead is 

 narrower, the palpi stouter. 



Forehead in Bigot's type is parallel, about six times as 

 long as it is wide. A reddish-yellow species, the dorsum of 

 thorax darker. Legs reddish yellow. Wings tinged brown. 



Length 14^ mm. 



Tor detailed description see Mr. Taylor's account.

Tabanus lorentzi, Ricardo, Resultats Exped. Sci. N^erlaudaise, Nouv.

Type (female), in fair preservation, from Australia, and a 

 long series of females from Townsville and Kuranda, N.E. 

 Queensland, in Mr. Waimvright's Coll. 



Having examined Bigot's ty])e, 1 find my species is iden- 

 tical, only differing in the colour of the legs, which is some- 

 times darker, the apical joints of tarsi often blackish, and 

 the apex of antennae is sometimes darker.
