_Distribution in Nebraska._--Eastern part of state.
_Records of occurrence._--Specimens examined, 23, as
follows: ADAMS CO.: Hastings, 1 (Hastings Museum, Hastings,
Nebraska). CASS CO.: 1 mi. NE Louisville, 6; Plattsmouth, 1
(Univ. Nebr. State Mus.). SARPY CO.: 1/2 mi. W Meadow, 15
(Univ. Nebr. State Mus., 7).
_Remarks._--We have observed this bat hibernating in the limestone
quarries of Cass and Sarpy counties, where it was commonly found in
drill holes or clinging to the ceiling or walls. We have always found
this bat to be solitary while in hibernation, with one exception. On
January 31, 1949, a male and female were found in the same drill hole
in the Cass County quarry. The jolt of being knocked from the hole
separated the two bats, and upon examination the penis of the male was
noted to be extended and erected, indicating that the pair might have
been in the act of copulation.
