ARGYNNIS VII. 
might be, I found the change passed, and the beautiful chrysalis formed, the 
sense of relief was great. It was the single outcome from at least three hundred 
eggs, and I had watched over it in one stage or other almost daily for thirty- 
eight weeks. 
From this chrysalis a female emerged twenty-four days later, nearly forty-one 
weeks from the laying of the egg. As the several stages of these larvae were 
reached, they were forwarded to Miss Peart, in Philadelphia, for their portraits, 
which in every instance are drawn from life, and fortunately none were lost or 
injured on their travels. 
In the fall of 1874, I again obtained eggs of Cybele , and profiting by experi¬ 
ence, confined the young larvae within cylinders of fine wire set over the plants 
and deep enough in the earth to prevent escapes. And I found no difficulty, 
after the larvae began to feed, in rearing them, bringing seven to the imago. 
Fresh air and moisture is what these larvae of Argynnis require, and I have no 
doubt now that I can successfully raise any species of this genus. 
Three years ago, I received from Mr. Wm. Saunders, a few half-grown larvae 
of Cgbele, taken near London, Canada. They were found by him in the Spring, 
in swampy ground, hiding by day in holes made by the feet of cattle, and were 
concealed also by dead leaves which more or less filled the holes. These larvae 
matured in my possession. Mr. Saunders also found chrysalids of the same 
species suspended on the under side of pieces of bark near this swampy ground, 
and by scattering bark about, and frequently examining it, he obtained several 
chrysalids. In the same sort of hiding place, Mr. Mead found the chrysalis of A. 
Atlantis, at Hunter, N. Y r ., in spring of 1873.
