Hendrickson 1950 Mystic volana (2) Aug. 25 Lower Corington Flat, 5000 ft., Riverside Co., Calif. Went with Ward & Jerry Russell at about 8:45 P.M. to check tunnel at Corington springs for bats. About 1/3 of way back noted individual flying back and forth between me and far end of tunnel. Netted it with a butterfly net. It had apparently been disturbed from a night roost by the sound of our voices in the tunnel.
