Declana egregia. 



Air. Robert Dunlop, of Orepuki, has taken a fine series of 

 this handsome moth ; in fact, lie found it to be one of the 

 most frequent visitors to the electric hght. It seems to be a 

 constant form in a very variable genus. 



D. hermione. 



Several at light, Orepuki. 



D. griseata. 



One at sugar at West Plains, and several at Orepuki. 

 Very variable. 



Erebia pluto. 



Fairly common on the mountains round Lake Wakatipu. 



Erebia butleri, 



Humboldt Range. I am indebted to Mr. G. V. Hudson 

 for examples of this and the preceding species. 



Chrysophanus salustius. 



There is a great difference between northern and southern 

 forms. Typical Wellington males are almost one-quarter 

 larger, and exhibit very little of the dark-brown colour, the 

 spots being reduced to mere dots, and the terminal bands 

 being very narrow. Examples from this district have tlie 

 brown colouring extending from base to about ^, and broad 

 borders of the same colour on costa, termen, and dorsum ; 

 the spots are also large, and in many cases form unbroken 

 bands. Altogether, our variety of sahistius much more nearly 

 resembles C. enysii than Wellington specimens of salustius. 

 An apparently constant distinction between enysii and salus- 

 tius will be found in the colour of the cilia of the hind wings. 

 In sahistius this is bright-yellow, in enysii dull-orange. 



Diptychophora persophanes. 



Very common here among manuka during summer. I 

 have also examples from Dunedin and Lake Wanaka. 



D. lepidella. 



West Plains, Dunedin, and Lake Wanaka. Probably 

 generally distributed wherever manuka {Leptospermuvi) is 

 found. 



D. interrupta. 



Lake Wanaka and Ida Valley. Mr. Lewis informs me 

 that Ida Valley specimens are duller and more inconspicuous 

 than Lake Wanaka forms.
