238 BiUterjiies of the Tosemitc Valley. [zoe 



Parriasshis claruis 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 vienapia Feld. — Of this species I saw only about three 

 specimens. They were in a 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 eury theme 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 canons 

 or hovering over the milkweed. Several larvae 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 valle^^s. 



Heterochroa 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. 



L-hnenUis lorqicini 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. 



Argymiis monticola Behr; Argynnis ze7'ene Bdv. — These two 

 species were always found together, the former being the most nu- 

 merous generally. Very common through the mountains at al'i- 

 tudes below nine thousand feet. They delight in sunshine, and ai e
