proved to ray own satisfaction (but not to that of some others), 

 that P. atalanta cannot pass the winter as an imago. I have for 

 the past ten years experimented with the species, and the only 

 way in which I can carry it successfully through the winter, is by 

 feeding it regularly. 



" I grant that several undoubted records are to hand of the imago 

 being found alive in January and February, among them that of 

 my friend Mr. Barnes, of Farnborough, whose record is without 

 dispute ; but his finding the species apparently hybernating does not 

 prove that those specimens were going to live till April or May and 

 pair and carry on their race. We all know that in mild autumns 

 and winters you can find larvae and pupte in November and 

 December, and we usually bring these into a warm room and breed 

 out the imago in December or early January. Why should not 

 these found specimens be very late natural emergencies, say, 

 January ones, and that being the case, they would live for a few 

 weeks without food tucked snugly away amongst creepers, but 

 would die off before the spring. We have, many of us, caught in 

 April or early May absolutely perfect specimens, which look as if 

 just out of the pupas, and my discovery that the species can remain 

 as a pupa through the winter seems to clear up the mystery of 

 these fresh specimens. 



" I wish it clearly understood that I am still of the opinion that 

 we are almost entirely dependent on immigration for our supply of 

 P. atalanta." 



Mr. R. Adkin remarked on the importance of Mr. Newman's 

 observations in bringing such definite information on a point in the 

 life-history of P. atalanta, which had hitherto eluded one's 

 knowledge. 



Mr. Frohawk said that P. atalanta was on the wing all the 

 winter in suitable weather in the Scilly Isles. It apparently had a 

 hibernating stage, but there was a succession of broods throughout 

 the year. The temperature of these islands was uniformly warm, 

 varying from 47° in winter to 57° in summer. 



Mr. J. Platt-Barrett said that P. atalanta was to be seen all the 

 winter in Sicily on favourable occasions. 



Mr. F. W. Frohawk exhibited a large number of lantern slides of 

 bird subjects, and gave an address on them, including much first 

 hand information of his own observations in the Scilly Isles and 

 elsewhere. He subsequently contributed the following notes 

 containing a resume of his remarks on
