The present paper deals with the chromosomes observed in male germ cells of Euscyrtus karyni and E. formosanus belonging to the Podoscyrtinae of the family Gryllidae. No numerical and morphological differences of chromosomes were observed between these two species, as clearly seen by reference to the accompanying figures (Figs. 1-11) and the table given below. The only visible difference lies in the size of cell; Euscyrtus karyni is larger in its cell size than E. formosanu.
