SUPPLEMENTARY NOTES UPON ARGYNNIS MYRINA, WITH 

 MENTION OF THE SPECIES BELLONA, ATLANTIS 



AND CYBELE.

I was again in the Catskills, i8th August, this season, and remained 

 there till October. On 20th August I found niyrina abundant, and easily 

 obtained eggs, laid 21st. These hatched 29th. The larvae passed ist 

 moult 6th Sept., 2nd moult nth, and by 20th had become lethargic, 

 gathering in small clusters on the leaves which I gave them. A second 

 brood hatched 22nd Sept., from eggs laid on 8th. Time 14 days, or 

 nearly double that of the other brood. These larvae also reached 2nd 

 moult and became lethargic. Still another brood I obtained a week 

 later, and when I left the mountains these had not reached the 2nd moult, 

 but lingered after the first. The weather was cold, and though the larvse 

 fed, their periods were greatly retarded. I was endeavoring to see if the 

 latest broods of the year might not perhaps hybernate immediately after 

 the egg, as those of cybele do. But I discovered nothing to lead me to 

 conclude that such was ever the habit of this species. These last larvse 

 were not living when I again reached Coalburgh. 



The latest female myri/in which I saw on the wing was on i6th Sept., 

 but not having a net with me, I was unable to take her. 



Argy7inis bellona was less abundant, and at first seemed extinct, but I 

 discovered that it frequented certain spots, especially where a particular 

 species of Solidago grew, showing a great partiality for the flowers ; and 

 by often visiting these places, I obtained several females. These laid 

 about fifty eggs on violet. First eggs 23rd Aug., and they hatched 31st. 

 The larvae passed ist moult 6th Sept., 2nd nth, and some of them 

 passed the 3rd moult 20th Sept. A few days after, both those which had 

 passed the 3rd, and the others which had stopped at the 2nd moult.became 

 lethargic. But I had sent some larvae of same lot, in their first stage, to 

 Miss Peart, at Philadelphia, and all of them went on to chrysalis and 

 imago. 



A second brood of bellona from eggs laid 31st Aug., went on to 2nd 

 moult, and ail these became lethargic ; and these, as well as the others, 

 and the lafvae of myrina, I have here at Coalburgh.
