If the proper rhythm is observed the imitation is so successful that one might well be deceived by it.
In the musical apparatus of the Pine-chafer the pad of the finger-tip and the scrap of indiarubber are represented by the soft abdomen of the insect, and the glass is represented by the blade of the wing-cover, which forms a thin, rigid plate, easily set in vibration.

The sound-mechanism of the Pine-chafer is thus of the very simplest description.

The vibrations of the male Cigale's cry would cause a resonance, a vibration, in the body cavities of other male Cigales, and to a lesser extent in the smaller cavities in the bodies of the females.

Other sounds would cause a slight shock, if loud enough, but not a perceptible vibration May not this vibration--felt as in a cathedral we feel the vibrations of the organ-pipes in the bones of the chest and head or on the covers of the hymn-book in our hands--serve to keep the insects together, and enable the females to keep within sight of the males?
The sight of an insect is in one sense poor--it consists of a kind of mosaic picture, and for one insect to distinguish another clearly the distance between them must not be very great.
