FIGURES 13–27. Oscillograms of male calling songs of Gomphocerus sibiricus (L.). 13–14, 16, 20, and 24―male from the Central Tien Shan Mts., 15, 17, 21, and 25―male from Buryatia, 18, 22, and 26―male from Irkutsk Oblast, 19, 23, and 27―male from Chita Oblast. 13–15―general view of a song, 16–19―main part of a song, 20–23―end part of a song, 24– 27―main part of a song at higher speed. For males from Irkutsk Oblast and Chita Oblast only parts of songs are presented.
