Cyclotron instability is studied in a homogeneous plasma with an anisotropic non-Maxwellian distribution of ions and with Maxwellian electrons. It is shown that plasma can be unstable at any ratio between mean transverse and mean longitudinal ion energy, if the ion distribution function for the transverse velocities is a nonmonotonous function. The beam'' character of the function is in this case the physical cause for appearance of this type of instability. The quasitransverse'' waves are the most unstable waves, propagating almost perpendicularly to the external field. Plasma stability improves with the increase of electron temperature. If the mean transverse ion energy is much larger than the longitudinal energy, the effect of nonmonotony of the function becomes unessential, and previous results remain valid for cyclotron instability.
