We compare the quantum and the classical description of the two-dimensional
motion of electrons subjected to a perpendicular magnetic field and a one-
dimensional lateral superlattice defined by spatially periodic magnetic and
electric fields of large amplitudes. We explain in detail the complicated
energy spectra, consisting of superimposed branches of strong and of weak d
ispersion, by the correspondence between the respective eigenstates and the
''channeled'' and ''drifting'' orbits of the classical description. [S0163
