I am indebted to J*rof. Dr. Bezzi for informing me that the 

 name Elaphrom/yia 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, Ricardu. 

 Corizoneura kurandae, Taylor. 



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

 Linn. Soc, N.S. Wales, 1916. XL!., 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 specimen of this species 

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

 namee.
