WE have found that the male of Nauphoeta cinerea stridulates during courtship. The male raises his wings and tegmina when courting the female, and exposes his tergum1. The female responds to a pheromone (seducin), produced in the male\&$\#$39;s abdomen, and mounts and palpates or \“feeds\” on his tergum2. The male initially courts without stridulating, and if the female is receptive, mating will occur quickly. If the female does not respond by mounting and feeding, however, or if she does mount and the male\&$\#$39;s attempts to grasp her genitalia are unsuccessful and she dismounts, he lowers his tegmina and wings, touches her with his antennae or legs, or stands within about 2 cm from her and stridulates. The male stridulates when the female remains quiescent; if she begins to move about he stops stridulating and usually turns facing away from her and raises his tegmina and wings.

Males of Nauphoeta cinerea stridulate when they court non-receptive females. The stridulating apparatus consists of parallel striae on the lateroposterior margins of the pronotum and on the proximal region of the costal veins of the tegmina. The sound is produced by posterior, anterior, and side-to-side displacement of the pronotum rubbing against the costal veins. Phrases usually consist of two to six complex pulse trains followed by a long series of disyllabic chirps, and they are linked to form sentences lasting as long as 3 min. The song consists of a broad band of frequencies up to about 15 kHz with intensities of 55 to 65 dB, re 0 dB = 0\·0002 dyn/cm2, at 1 cm.

From the calculations of Pierce nearly two decades ago, students of the production of sound in bush crickets have assumed the area of thin cuticle on the right tegmen known as the \“mirror\” to be acoustically important (Fig. 1). Pierce\&$\#$39;s attribution of a resonant function to this membrane was challenged by Broughton and Dumortier. Dumortier suggested that the whole tegmen is responsible as an acoustic coupler, not only the mirror. Broughton, working on the decticine, Metrioptera roeselii (Hagenbach), found that the frequency spectrum of one individual was not obligatorily changed by coating the mirror with a deadening film of latex. His results have stimulated further work of the same nature on two members of the Conocephalidae, Conocephalus discolor (Thunberg) and Homorocoryphus nitidulus nitidulus (Scopoli). Both these animals, like M. roeselii, have a well-defined spectrum, but their peak frequencies are at 28 kc/s and 15.5 kc/s, respectively.
