The sounds produced by Parapellopedon instabilis (Rehn, 1906), are described for the first time on the basis of recordings made, in captivity, with an analogical tape recorder. The signals were digitized in the laboratory and analyzed using a software. Three types of song are described: the male calling song, typical of the gomphocerinae species, the female\’s agreement song, less organized temporally and unusually loud for a gomphocerinae species, and disturbance songs among males and among females, which follow the typical structure of these signals in the subfamily. Oscillograms and frequency spectra of all songs are given. The stridulatory file of both sexes, male and female, are described.

The sounds produced by Metaleptea adspersa (Blanchard 1843) were recorded in captivity with an analogical tape recorder. The signal was digitized in the laboratory and studied with a software. Three types of sound were described: copulation, rivalry, and crepitation. All three sounds were produced only by males. The frequency of the sounds occupied a broadband, from 3\–4 to 16 kHz, although the main peak frequency for each type of song differed. We also studied the structures involved in sound production. Copulation and rivalry songs were produced by the rubbing of the subcostal, radial, medial, and cubital 1 veins of the hind wing against the subcostal and radial veins of the tegmen; the enlarged cubital area of the hind wing acted as a resonator. Crepitation sound was produced by the cubital area of hind wing when its expanded membrane became taut.
