Beetles' Music.

While the structure of the music or stimulating organs of beetles is extremely simple, they sometimes possess contrivances for varying the pitch. The general structure of such an organ is a hard surface covered with striations, over which some other member of the body furnished with a rasping edge or area is rubbed. When the striated edge is divided into parts with finer and coarser markings variations of pitch can be produced.
