Electromagnetic waves propagating at an angle with respect to the magnetic field in a finite-..beta.. plasma with hot electrons and cold ions are analyzed. The wave frequencies lie between the ion and electron gyrofrequencies. In the case of a slight anisotropy and a slow electron beam there is a resonant two-stream instability at a frequency near the whistler frequency. It is also found that a nonresonant two-stream instability occurs in the case of an isotropic plasma if the hydrodynamic pressure of the electron beam is higher than the magnetic pressure. Drift waves are analyzed for a slight anisotropy of the plasma temperature. The cold plasma component affects the drift--anisotropy and beam--anisotropy instabilities.
