In this paper we present further results of an intensive photometric campaign on some bright southern Be stars to search for periodic light variations. In order to obtain good phase coverage, many observations were conducted from two sites with different longitudes: ESO and SAAO. As in Paper I, we found a large fraction of early-Be stars to be variable with periods close, or equal to their rotational periods. Particular attention was devoted to the late-Be stars. Unlike the hotter members of this class, the late-Be stars do not seem to have detectable periodic light variations except for one or two stars of very small amplitude.
