By using the kinetic theory, the dispersion relation of obliquely propagating electrostatic waves are discussed for three types of kappa distribution function: 1) loss-cone-bi-kappa-Maxwellian distribution, 2) current carrying Bi-kappa-Maxwellian distribution and 3) product-bi-kappa distribution. The effects of kappa-index, loss-cone index, streaming velocity and the temperature anisotropy on the Harris instability is highlighted for their possible application to explain the banded emissions observed in the terrestrial magnetosphere and in the magnetospheres of other planets, e.g., Jupiter, Saturn, Uranus, and in Io's plasma torus.
