238 Butterflies of the Yosemite Valley. [ ZOE 
Parnasstus clarius Eversmann.—Quite common around the bogs. 
and wet places, between Lake Tenieya and Tuolumne Meadows. 
The average altitude here is about nine thousand feet. In manner 
of flight they much resemble the species of Satyrus. 
Pieris sisymbri Bdv.—Several of these were caught on the top of 
Sentinel Dome, July 11. They fly around while it is quiet, but 
seek shelter as soon as it begins to blow at all hard. 
Neophasia menapia Feld.—Of this species I saw only about three 
specimens. They were ina yellow-pine forest on the south side of 
Lake Eleanor. 
Anthocharis ausonides Bdv.—Several specimens of these, in a very 
fresh condition, were caught. They were found around the mead- 
ows in the lower altitudes. 
Colias eurytheme Bdv.—Found about every meadow in the re- 
gion, even up to ten thousand feet altitude. The albino female was. 
also quite common. 
Colias behrii Edw.— Only one specimen of this scarce butterfly 
was seen. This was disturbed from its resting place in the grass, 
while our party was crossing a small meadow on the side of Mt. 
Lyell. It is found on several of the high peaks around Tuolumne 
Meadows, as well as occasionally in the meadows themselves, but. 
nowhere is it a common butterfly. - 
Danais archippus Fab.—Quite common up to an altitude of about 
six thousand feet, and is commonly seen sailing across small cafions 
or hovering over the milkweed. Several larvze of it in different 
stages of development were also observed on the milkweed. The 
habits of the butterfly in the mountains do not seem to me different 
from those I have observed in the valleys. 
Hleterochroa Californica Butl.— Quite common in the valleys 
throughout the region. These butterflies have a curious habit of 
coursing up and down the roads and paths, much in the manner of 
large dragonflies. 
Limenitis lorquini Bdv. — This species was found in about the 
same localities as the preceding. Neither of them were observed 
at higher elevations than six thousand feet. } 
_ Argynnis monticola Behr; Argynnis zerene Bdv. — These two. 
species were always found together, the former being the most nu- 
merous generally. Very common through the mountains at alti- 
tudes below nine thousand feet. They delight in sunshine, and are ~
