The theory of direct excitons in crystals of diamond and sphalerite type is generalized to the indirect exciton case. The problem is solved by the variational method taking into account the anisotropy and the nonparabolicity of the electron band. The comparison with the theoretical and experimental data known from literature is carried out.
