A change of name is necessary for Taylors species, as T. minor has already 

 been utilised by Maeqiiart (Dipt. Exnt.. Suppl. 4, 1850. p. .S3) for a species from 

 Patagonia.

We ha\e compared a long series of T. ref/is-georgii with specimens of T. 

 hrishanen^is Taylor received from the Queensland ^Museum, and with the type of 

 T. spadix, and are imable to discover any tangible differences. The species is a 

 very variable one in the colour of the clothing, in the width of forehead and 

 shape of callus. 



The Tasmanian specimens referred by Mr. Taylor to T. bri-'ibaneiisis are evi- 

 dently the species described by one of us (E.W.F.) as "T. daemenensis. distin- 

 guished by the facetting of the eyes in the male. 



For our identification of T. regis-georgii we are relying on Miss Ricardo's 

 determination of the species in the British Museum. At tlie same time it seems 

 unlikely, though not impossible, tliat the range of our east coast species extends 

 to King George Sound. On the other hand we have seen Victorian specimens. 

 Should the species from King George Sound prove to be different it will be 

 necessary to re-establish the name T. spadix.

This does not a]>pear to have been identified in Australian collections of Aus- 

 tralian Tabanidae since it was first described, though Bigot has referred a second 

 species from Chili to the genus. 



We have specimens before us of a species that agi'ees fairly well with both 

 generic and specific descriptions with the exception that there are the usual five 

 divisions on the tlurd joint of tlio antennae. The dirisions are however, obscure 

 and might readily be miscounted, and the base of the third joint is not angulate 

 but somewhat swollen in the middle, corresponding in this respect to Macquart's 

 description. 



The species is alHed tu '/(dndiii.t ncntilis Erichson. and 7'. frii;igatti Ric. liut

 posteriorly so that the fcu'eliead is relatively shoi-ter and bi-oadcr than in these 

 species. 



Walker's notes on the genus are valueless, as lie placed therein two species 

 now referred to Pelecorrhynclnts and some of tlie generic characters given by him
