Art. II. — Note on Chrysophanus feredayi. 



By Captain F. W. Hutton. 



[Read before the Philosophical Institute of Canterbury, 4th July, 1900.] 



There seems to be some doubt in the minds of entomologists 

 as to what is the insect described as Chrysophanus feredayi by 

 Mr. H. W. Bates. Mr. G. V. Hudson, in his " New Zealand 

 Moths and Butterflies," says that it appears to be a variety of 

 G. salustius (pp. 116, 117), and he includes G. rauparaha, of 

 Fereday, as a variety also. 



As the collection of the late Mr. Fereday has come into the 

 possession of the Canterbury Museum, I am in a position to 

 clear up this ambiguity, for the collection contains the type 

 of G. rauparaha and a cotype of C. feredayi. 



The following is the original description of C. feredayi, by 

 Mr. Bates : — 



"C. ednce, Doubled., simillimus ; differt palpis antice gri- 

 seoalbo et nigro hirsutis, alis posticis subtus brunneo ne- 

 bulosis, $ 2 ■" 



" Similar in size, form, and colours to C. edna, but differs 

 from all the varieties of that species in the palpi in front being 

 clothed with whitish hairs mixed with black instead of yellow 

 hairs. The black marks of the upper surface are also larger 

 and more confluent, and the under-surface of the hind wings 

 is yellow, with a broad curved discal patch and a wide 

 posterior border (confluent at the apex) violet-brown. The 

 wings above are violet-black, with the discal area and a 

 macular belt of six quadrate spots on both wings shining-ful- 

 vous, the discal area in the fore wing being divided by three 

 spots and the black nervures, and on the hind wing by one 

 spot. There is a submarginal row, also of tbree fulvous 

 spots, near the anal angle of the hind wing, and the basal 

 fourth of both wings is clothed with tawny-brcwn hairs. 

 Both sexes are alike in colours and markings." 



This description agrees accurately with the cotype in the 

 collection. It also agrees with the description and figures of 

 C. enysi by Mr. A. G. Butler, and no doubt the two are 

 identical. 



The species described and figured by Mr. Butler as G. 

 feredayi is a different species, and is identical with the G. 

 rauparaha of Mr. Fereday. Mr. Hudson thinks that this 

 is only a variety of G. salustius, but it can be distinguished 

 from that species not only by the fuscous shade of the lower 

 surface of the hind wings, but by the palpi, which are white,
