Satyridae 
8. Oeneis brucei (Edw.). A female taken by J. D. Eff 
at Berthoud Pass (elev. between 11,000' and 12,000'), 
Gilpin Co., Colo., was confined 16 July 1949 over a sedge. 
It oviposited freely at Eldora, at an altitude about 8,000 
feet lower than the normal occurrence at Berthoud. The 
larvae emerged and fed readily, but all died en route to 
Connecticut or soon after arrival there. 
9. Oeneis lucilla B. & McD. A female taken at about 
13,000' on Mt. Evans, Clear Creek Co., Colo., was confined 
over sedge. At Eldora, over 4,000' lower than the point of 
capture, this female laid several ova on 29 July 1949. My 
records do not show whether the ova were fertile; in the 
collection are four preserved ova but no larvae. 
10. Erebia epipsodea Butler. On 11 July 1949 females 
from Eldora were confined, each over a grass and a sedge. 
In two days 19 ova were laid, nearly all on the grass, but 
a few on the sedge; the grass was distinctly preferred for 
oviposition. The ova were fertile. 
Nymphalididae 
11. Boloria eunomia alticola (B. & McD.). On 30 July 
1949 females were found in fair numbers in a large alpine 
bog at Caribou (elev. 10,000'), Boulder Co., Colo. Many 
were followed closely, but they did not seem strongly- 
inclined to oviposit and, further, the strong wind made it 
difficult to keep track of a given individual. However, one 
female was observed ovipositing and the two ova were 
recovered. The behavior of this female was unlike that of 
all others (of both sexes) watched. This one alighted on 
the lowest plants on small hummocks rising a few inches 
above the standing water of the bog; the others always 
came to rest on shrubs and the flowers of tall herbs. The 
ovipositing female crawled for several seconds into the 
rather thick low plants (largely Graminales and a tiny 
Thalictrum) and stopped twice to oviposit on leaves of 
Thalictrum alpinum L. var. hebetum Boiv. [R.C.R.]. The 
ova were later lost, and captive females did not oviposit,
