Tadiytes australis, Saus?., 1S67 (nee Saussure, 1854), is 

 almost certainly a Tachyspliex, but I am unable to identify 

 it. In dealing with Australian Tachysj'hex in a former paper 

 (Proc. Zool. Soc. p. 491, 1908), I mentioned a doubtful 

 record of the Xew Zealand .species T. nigprrimus, Sm., from 

 Victoria ; this is certainly a case of mi.^taken locality. I 

 have seen no specimens of T.Jruncatifrovs in recent collec- 

 tions, and it is possible that the locality on the type at 

 Oxford is erroneous.
