vot. uI.| Butterflies of the Yosemite Valley. ee, 
always to be found on open hillsides or other such warm spots. In 
view of the fact that I have found these two butterflies together here, 
as well as in Shasta county two years ago, it seems to me hardly 
possible that they are more than mere color varieties of the same 
species. 
Argynnis leto Behr.—This handsome Argynnid was found quite 
often. It is a strong and rapid flyer, and is quite hard to capture, 
partly from the above cause and partly from its habit of flying 
around the wet places of the meadows. No females were observed 
by me on the entire trip. 
Argynnis egleis Badv.—Only three specimens of this high mount- 
ain form were captured. One was caught on the upper Tioga road, 
and the other two on the Lyell fork of the Tuolumne river. It 
strongly resembles monticola and zerene in its habits, though it is a 
weaker butterfly, flying slower and closer to the ground. 
Argynnis epithore Bdv. — This, the smallest of the Argynnide 
found in that region, is quite common in the open regions of the 
high altitudes. In manner of flight this species much resembles a 
Melitz:a or even some of the species of Satyrus. 
Melitea palla Bdvy.—Found throughout the region traveled, up 
to moderate altitudes. 
Melitea leanira Bdv.; Melitea quino Behr.—Only one specimen 
of each of these was captured. They were found July 9 on the 
north edge of the Yosemite Valley. ; 
Phyciodes mylitta Edw. — Several specimens from different parts 
of the region traveled. 
Vanessa antiopa Linn. — Several specimens observed. Most of © 
them were at medium altitudes, though one was seen at the foot of 
Mt. Lyell at an altitude of about ten thousand feet. It ranges still 
_ higher, probably. : 
Pyrameis cardui Linn.—Very common, even up to high altitudes. 
This is one of our hardiest species, being often seen on some of the 
coldest and windiest ridges in the mountains. : 
Pyrameis carye Hbn.— Quite common, but not found at such 
high altitudes as the preceding. 
Pyramets huntera Fabr. Several of these were seen around water 
~ courses in the lower valleys of the mountains. This does not ap- 
pear to be quite as hardy a butterfly as either of the two preceding, 
though it is found quite late in the autumn, around the bay here.
