OBSERVATIONS ON THE FLYING-HABITS OF BUTTERFLIES. 919 
separated before I could induce them tq fly. The ? kept its wings 
open and showed an inclination to crawl about, the g keeping its 
wings folded tightly. (Suggests that the 9 would carry.) 
Genus Nisoniades. 
N. tages, observed three times. At Follaterre, Valais. July 29th 
1916. 9? carried §. At Caux, Vaud. June Ist, 1917. ¢ carried 
3. In the Stockenwald, Kandersteg, Bernese Oberland. May 22nd 
1918. © earried g. 
Genus Chrysophanus. 
C. hippothoé var. ewrybia, observed once. At Lenzerheide, Grisons. 
July 19th, 1919. @ carried 9. 
Genus Loweia. 
L. subalpina, observed once. At Spoina, Lenzerheide, Grisons.

Genus Rumicia. 
R. phiaeas, observed once. At Vernayaz, Valais. August 22nd, 
1916. @ carried S. 
Genus Lycaena. 
L. arion, observed once. In the Ueschinen Tal, Bernese Oberland. 
June 13th, 1918. ¢ carried g. 
This is very interesting in view of the fact that among all the 
“blues” (with one other exception, so far as is at present known) the 
g carries. Records of the habits of arcas, euphemus, alcon, mnelanops 
and iolas would be most instructive. 
Genus Cupido. 
C’. sebrus, observed once. At Follaterre, Valais. May 9th, 1916. 
é carried °. 
Genus Everes. 
Bhs lenis. observed twice. At Branson, Valais. May 18th, 1916. 
gf carried 9. July 29th, 1916. ¢ carried 9°. 
Genus Glaucopsyche. 
G. cyllarus, observed ones. By the Gryonne River, St. Triphon 
Vaud. May 2nd,1916. ¢ carried 9°. 
Genus Cyaniris. 
O. semiargus, observed once. In the Ueschinen Tal, Bernese 
Oberland. June 380th, 1918. 9? carried g. The only ‘“‘blue” beside 
arion as yet recorded with the @? carrying. 
Genus Aricia, 
A. eumedon, observed once. At Masons, Lenzerheide, Grisons. 
July 8rd, 1919. I took a pair but could not make them fly. While 
falling to the ground after being thrown into the air, the ? expanded 
her wings, but did not try to fly, the ¢ did notmove. Is this another 
‘‘blue”’ species of which the ? carries? Unfortunately I have not 
had the good fortune to observe medon or donzelit.
