midsummer or late summer, is that the insects which he sees at 

 high altitudes and appearing peculiar to that level, may in late 

 spring or early summer frequent the valley region as well. 



This is true of Melitaea palla which practically disapears 

 in the valley before July, but only commences to come out in 

 the mountains in the Canadian zone when that month is well 

 initiated. L saepiolus usually a resident of the Canadian, oc- 

 curs sparingly in the valley at an early date. L. fulla and 

 sagittigera, earlier in the valley were usually much later in the 

 mountains. Parnassius clodius was seen on several occasions 

 at 1900 ft. in June, but were just emerging at an altitude of 

 6000 ft. July 10. The June specimens must have emerged in 

 the valley region, since there were none in the mountains at 

 that date. Among the moths, Sphinx perelegans comes out 

 about one month later at Echo Lake, altitude about 6500 ft., 

 than it does in the valley, elevation 1900 ft. Alypia langtoni 

 likewise is early in the valley and late in the mountains. The 

 exquisite little Gyros mnirii was in fine condition at Echo Lake 

 on July 10, 1907. On June 12, 1903 a hardly recognizable speci- 

 men of this species was taken in the Castle Creek Canon, at an 

 elevation of 2000 ft. 



PAPILIONOIDEA. 



1. Anosia plexippus Linn. Quite common in 1907 in the valley where 

 milkweed was abundant. A specimen from Echo Lake is quite a good 

 deal darker in color than valley examples. 



2. Argynnis leto Behr. Rare at Castella, but not uncommon at Sis- 

 son further north. 



3. Argynnis oweni Edw. Not rare in the mountain meadows in July 

 and August, flying also in the uppermost Transition in the more tree- 

 less areas. This is strictly a mountain form; the type locality of the 

 species is Mt. Shasta, elevation 7,500 ft. (Owen). 



4. Argynnis serene Bdv. The most common "fritillary" of the reg- 

 ion, and confined chiefly to the valley where it flies with the following 

 species. 



5. Argynnis monticola Behr. Quite common, the larger var. pur- 

 purasccns Hy. Edw. rarer. Zerenc and monticola were just putting 

 into appearance when my brother and I reached Castella at the end of 

 June in 1907. The males come out earlier than the females, and both 

 sexes are very fond of feeding at the flowers of Apocynum androsae- 

 mifolium var. pumilum, a small plant common by the roadside. The
