this ocean. We may, therefore, not ^vouder that circumstances may 

 combine to carry this hardy and by no means delicate insect from the 

 New to the Old World. 



With regard to the probability of Anosia Flexippus becoming a 

 permanent resident in our islands, there is, I think, nothing in our. 

 climate to prevent its continuance here except, perhaps, the dampness 

 of our summer. We have, however, no plant of the natural order 

 Asclepiadacece native to our flora, so the larva would have to find a 

 substitute food. According to Mr. E^iley, how^ever, the larva is some^ 

 times found on the Dogbane (Apoci/mim), and in the South of England 

 we have two plants of the same natural order (Apoct/nacece), the 

 Periwinkles, Vinca major and minor growing plentifully wild, or at all 

 events naturalized in many places. The Oleander, another shrub of 

 the same Order, is grown in the South of England with only slight 

 protection during the winter, and I believe that one or two species of 

 Asclepias are occasionally grown in gardens. If, therefore, as Dr. 

 Jordan suggests (p. 211), the newly arrived " colonists " be not too 

 eagerly caught up, but allowed fair play and a chance to perpetuate 

 their race, it may be that in future years Anosia Flexippus may figure 

 iu our lists as a (naturalized) " Britisher," and perhaps in part make 

 up for the great loss our insect fauna sustained when the " Large 

 Copper " was improved off the face of the earth. 



In the South of Europe, besides the advantage of a warmer and 

 drier climate, a probable food-plant exists in the Asclepias vincetoxicum, 

 which is common in the Mediterranean countries, and ranges through 

 Central Europe as far north as Denmark. Hence there is even a 

 greater chance of the insect, if it reaches these countries, establishing 

 itself there than in Britain. 



This paper may conclude with a list of localities whence specimens 

 of Anosia Flexippus have been obtained, which wnll give a fair idea of 

 its present distribution. 



The National collection possesses specimens from South Wales, 

 New York, Texas, Duenas (G-uatemala), Jamaica, St. Domingo, St. 

 Thomas (West Indies), Venezuela, Brazil, Honolulu, Upolu (Samoan 

 Is.), Tonga-tabu, Solomon Islands, Norfolk Island, and Cape York 

 (North Australia). The six specimens representing the species in the 

 Hewilson collection have no localities attached. 



In the magnificent collection of Messrs. Salvin and Grodman are 

 examples from E. United States, Colorado, Mexico, Guatemala, 

 Nicaragua, Costa Eica, Yeragua, Panama, New Granada, Ecuador, 

 Eastern Peru, Upper Amazons, Haiti, St. Thomas, Jamaica, Dominica,
