LEPIDOI’TERA. 
I 
the ease, and not having much to communicate respecting 
the habits of individual species, I shall confine my further 
remarks to a description of the insects in their final state, 
when they are exposed to view, and attract our notice by 
their neat and modest coloring, and their graceful and gentle 
motions. They are mostly found in thickets and woods, and 
more rarely in places more open and exposed. 
Hipparchia semidea, Say. The Mountain Butterfly. (Fig. 12G.) 
w ings dusky brown above, thin, delicate, and almost 
transparent, in the male 
paler, and with more of an 
ochre-yellow tint; fringes 
black, barred with ochre- 
yellow, and a row of faint 
ochre-yellow spots near 
the hind margin of the 
second pair ; the. under 
side of these wings and of the tips of the fore wings is mar- 
bled with black and white, a portion of the white forming 
an irregular band beyond the middle of the hind wings. 
Expands l T a j inch to 2 inches. 
This butterfly has hitherto been taken only on the summit 
of the White Mountains of New Hampshire in June and 
July. It was observed in great abundance flying about on 
the top of Mount Washington on the 29th of July last. It 
has also been seen on the Monadnoc Mountain, and will 
probably be discovered on the tops of the high mountains in 
our own State, if looked for at the proper season. It closely 
resembles .the Fortunatus of Lapland, with which I have 
compared it, and find it to be specifically distinct. Mr. Say 
was the first describer of it, and it is well figured in Ins 
American Entomology. Dr. Boisduval has since re-described 
and figured it under the name of Chionabas Also.*
