32 ENTOMOLOGICAL NEWS. [February, 



that hatched from them refused gooseberry, and would certainly 

 have died had I not supplied them with their ancestral food. Of 

 Argynnis, three species occurred, A. epithore in the Spring, 

 followed by what is probably A. monticola, though there seemed 

 to be two very closely allied forms, perhaps only varieties, in one 

 of which the marginal spots on the lower side of hind wings were 

 narrower than in the other and sometimes slightly touched with 

 silver. Both these forms were taken in coitu and always with a 

 mate of the same form. A. leto appeared still later, the first male 

 being seen July loth, and first female July 2ist. 



Of the other species captured, I will notice only the most in- 

 teresting. Lemonias virgulti was common in the Summer on 

 flowers and sage brush bushes, more especially on the talus around 

 the valley and above Vernal Fall. 



Thecla grunus occurred in swarms around the live oak trees 

 {Quercus chrysolepis} first appearing about July ist and continu- 

 ing all Summer. The full grown larvae were found in abundance 

 on young shoots of this tree about the first of June. Pyrgus 

 ericelorum was seen on only one day when we captured several 

 examples feeding on the flowers of the Pussy's Paws (Spraguea 

 umbellata), but saw none afterward, though we went to the same 

 place the next day. 



About the middle of September, after nearly all my larvae had 

 stopped feeding, we took a trip to the high Sierras to climb Mt. 

 Lyell, a peak 13,000 feet high. We left Yosemite on hore-back 

 with Mr. J. B. Lembert, as guide, who owned a small farm at 

 Soda Springs, high in the mountains, near the head of the Tuo- 

 lumne River before the place was included in the National Park. 

 On September 2oth we made the ascent of the peak, and when 

 about a quarter of the way up on a spur of the mountain over- 

 looking the end of the glacier, a specimen of Colias bchrii was 

 started up which I succeeded in capturing. No more were seen 

 that day as the weather soon became threatening, and by the 

 time we reached the top of the glacier, the clouds had begun to 

 float in over the peaks. On another day, September 22d, we 

 went to some mountain meadows, 10,000 feet high, where Mr. 

 Lembert had formerly seen some of the " little green butterflies" 

 (C behrii), but met with no success, and were obliged to return 

 almost immediately in a dense snow storm.
