The complex roots of the hot plasma dispersion relation in the ion cyclotron range of frequencies have been surveyed. Progressing from low to high values of perpendicular wave number k{perpendicular} we find first the cold plasma fast wave and then the well-known Bernstein wave, which is characterized by large dispersion, or large changes in k{perpendicular} for small changes in frequency or magnetic field. At still higher k{perpendicular} there can be two hot plasma waves with relatively little dispersion. The latter waves exist only for relatively large k{parallel}, the wave number parallel to the magnetic field, and are strongly damped unless the electron temperature is low compared to the ion temperature. Up to three mode conversions appear to be possible, but two mode conversions are seen consistently.
