Nonlinear modulation of quasi-monochromatic electromagnetic waves propagating parallel to an external magnetic field was investigated with particular attention to contributions of resonant particles at the group velocity. The contributions of these resonant particles give rise to a nonlocal- nonlinear term and modify the local-nonlinear term of the nonlinear Schroedinger equation. An explicit expresslon of a coefficient of the nonlocal-- nonlinear term is given for a plasma characterized by isotropic Maxwellian velocity distribution functions. In a vanishing temperature limit this coefficient becomes zero and the nonlinear Schroedinger equation agrees with that obtained by using a fluid model. (auth)
