which the zoological division into Palfearctic and Nearctic regions 

 does not apply. 



The purely American genus, Phyciodes, is not represented in 

 any part of the Palsearctic zoological region ; the highest develop- 

 ment of the group has been obtained in the Neo-tropical zoological 

 region, from which the species of the genus inhabiting North 

 America have been probably derived. 



The only species received from Hudson's Bay is Phyciodes 

 Tharos, Drury. It appears during tlie months of July and 

 August. The thirteen specimens sent do not differ very much 

 in colour or markings, except that some are darker than others ; 

 and in two specimens there is a wavy line running through the 

 black band at the lower edge of the upper side of the secondary 

 winjs. The insect is very plentiful in the district. 

 /" The collection, of which I have now given a description, small 

 /ks it is, is not wanting in interest. It is surprising to contemplate 

 the time which must have elapsed since the three identical with 

 European species had a common ancestor, and yet the difference 

 now existing is too slight to consider them even varieties of each 

 other. A former connection wdth Europe by the Faroe Islands, 

 Iceland, and Greenland, no doubt existed, and during one of the 

 periods of mild Arctic climate the transmission of species from 

 one continent to another was effected. We are so in the habit of 

 calling tliis hemisphere the Old World, that it does not occur to 

 us that it is just as likely that Vanessa Ant'iopa passed from 

 America to Europe, as that the converse was the case. ■ 



To Mr. Walton Haydon my thanks are du^Tor having 

 furnished me with the material used in the preparation of 

 these notes.

BUTTERFLY HUNTING IN NATAL: ON THE COAST- LANDS. 



By William D. Gooch, C.E. 



(Contiijued from p. C6.) 



The very close resemblance of these three insects, Danais 

 Eclieria, Pseiidacraa Tarqumia, and Acrcea Aganice, as they 

 circled and swooped in the lazy luxury of intense sunlight, was 

 most acutely watched by the veteran, who found difhculty in
