Specimens of Chri/sojii/i(-< arc represented in most of 

 the collections examined by me, and they invariably 

 belong to this variable species, two forms of which White 

 separated on colour and habits in Tasmania. 



An extreme foi'm is common at Trevallyn, Launces- 

 ton, which has an extra wide head, and the wings are 

 suffused with black anteriorly from the base and' i-each 

 to two thirds of the length of the costa. Mr. C. E. Cole 

 took a specimen approaching this form at Eltham, Victoria. 



Macquart's species from Tasmania was evidently cor- 

 rectly identified by White, and Bigot's sjaecies is probably 

 identical. White's type of C. faxinaniensiK only differs in 

 the colour of the legs and probably this, is the form 

 described by Walker from Australia as Leptix aqualh. 



A long series of specimens shows these forms merging 

 into each other and tnerefore they cannot be considered 

 distinct species. 



Hab. — Tasmania : Mt. Wellington, Hobart, Bagdad 

 Valley, Eaglehawk Neck, Mt. Maria, Launceston, Cradle 

 Mt. It has a wide distribution throughout Tasmania and 

 occurs from October to April. 



Victoria: One specimen, Eltham, 26th October, 1918. 

 (Collector.— C. E. Cole.) 



New South V/ales : One specimen from behind Sublime 

 Point, Thirroul, 30th March, 1918. Also a number in the 

 Macleay Museum. 



The type of ('. t(i>!iiiani('iisix. White, is in the British 

 Museum.

This species is European, and the Australian records are 



evidently incorrect. Neither Macquart nor Walker gave 



any definite descriptionsi, and it is impossible to determine 



what species they a.ctually had before them.
