"When captured alive the large ears are kept in a constant state of rapid tremulous motion, and the animal emits a low purring sound, which becomes a sharp scream when alarmed or irritated. When suspended at rest the tail and inter-femoral membrane are turned up, not in front, like the Rhinolophi, but behind, over the lower part of the back; neither does it appear to envelope itself in its wings so completely as does R. luctus." He then goes on to say he has noticed the tremor of the ears and facial crests in all the Rhinolophi when disturbed, and concludes with a graphic description of this species, sallying forth in the evening to prey upon the noisy Cicadas; leisurely wheeling with noiseless, cautious flight round some wide-spreading oak, "scanning each branch as he slowly passes by—now rising to a higher circle, and then perchance descending to the lower branches, until at length, detecting the unfortunate minstrel, it darts suddenly into the tree, and snatching the still screaming insect from its perch, bears it away."
Jerdon procured specimens at Darjeeling, and Kellaart says it is found in great abundance at Kandy and its neighbourhood; Kurnegalle Tunnel swarms with them.
