IN this communication we consider the left-hand mode in a hot plasma, propagating in the direction of the average magnetic field, and for frequencies near the proton gyrofrequency we find two new instabilities. The first is driven by strong electron thermal anisotropy and the second by strong proton thermal anisotropy in the presence of electron anisotropy. We believe that the first of these new instabilities may have important consequences for the development of the solar wind. This mode is similar to the low-frequency firehose instability but it involves only the electron anisotropy. The wavelength is short, and the destabilizing centrifugal force on the electrons is able to overwhelm the cyclotron damping due to the resonant protons. If this instability occurs in the solar wind, it results in an additional coupling between the electrons and protons, with the result that it can contribute to the proton heating.
