Phibalomyia, nom. nov. 

 Elaphrouiyia, Taylor, nee Bigot. 



Proc. Linn. Soc, N.S. Wales, 1916, XLI., p. 749 (1917), op. 

 cit., XLII., p. 517 (1917). 



I am indebted to Prof. Dr. Bezzi for informing me that the 

 name Elaphromyia has already been used by Bigot in 1859 (Dipt. 

 Trypaneidae), thus invalidating its use in the Tabanidae. I there- 

 fore propose the above alteration. 



Pseudotabanus queenslandi, Kicardo. 

 Coriioneura kurandae, Taylor. 



Ann. Mag. Nat. Hist., (8), XVI., p. 273 (1915); Taylor, Proc. 

 Linn. Soc, N.S. Wales, 1916, XLI., p. 748 (1917). 



I am indebted to Mr. Kershaw, Curator, National Museum, Mel- 

 bourne, for the courtesy of examining the Tabanidae contained in 

 the Museum Collections, where there is a .sj)ecimen of this species 

 named by Miss Ricardo, thus establishing the identity of the two 

 nameB.
