<strong>The</strong> Ageronia feronia makes a noise like that<br />

produced by a toothed wheel passing under a<br />

spring catch, and which can be heard at the<br />

distance <strong>of</strong> several yards: I noticed this sound<br />

front wings, which is probably connected with<br />

the production <strong>of</strong> the sound. For the case <strong>of</strong><br />

<strong>The</strong>cophora, see 'Zoological Record,' 1869, p.<br />
