color of the wings and the silvery spots on. the under side, but 
is a weak little creature, its flight being slow and feeble. It is 
usually very common in its season and may be seen clustered 
on the flowers to which it is partial, or flying lazily just over 
the grass tops of the damp meadow. On a small patch of mead¬ 
owy land they fly back and forth, not often venturing far from it 
onto the high land. 
The species is double-brooded, and inhabits the northern part 
of our country and Canada. It is a pretty little insect, as will be 
seen by reference to the transfer. The specimens for this work 
were taken in and about Wellesley, Mass., where it is usually 
very abundant. 
Another species much resembling A. myrina in size and gen¬ 
eral markings, but differing from it in not having the silvery 
spots beneath, is Argynnis bellona. This little butterfly is also 
very abundant and an inhabitant of the same character of coun¬ 
try as the preceding species, where it may be taken at the same 
time of year. 
Curiously enough, however, the two species do not mingle to 
any great extent and they will seldom be found equally numer¬ 
ous in the same meadow. This is often quite noticeable when 
two small patches of low wet land are divided by a ridge of 
high ground; one species may occupy one patch and the other the 
next, each keeping pretty well to itself. This is also a slow and 
weak flying insect, keeping close to the grass tops while on the 
wing and seldom venturing far from the low meadows. It is 
double-brooded like the preceding, and. is found over the north¬ 
ern half of the United States east of the Rocky mountains. It 
also occurs in Canada. 
Argynnis montinus is a rare little insect found on the barren 
tops of the White Mountains in New Hampshire. 
It much resembles A. myrina , except that it is darker and more 
reddish. The under side of the under wings is not adorned with 
the brilliant silvery markings of A. myrina , but with irregular white 
markings on a reddish brown ground. 
I have never been so fortunate as to see this butterfly alive, and 
although I visited Mount Washington and the other peaks near in 
the hopes of finding it, I was unsuccessful. 
This butterfly is supposed to have been stranded on the high 
peaks of the White Mountains at the end of the glacial period in
