We present ground-based follow-up photometry in the Geneva seven-colour photometric system of six new candidate beta Cep stars. The variability of these objects was originally found from the HIPPARCOS mission. From the new data we are able to confirm their beta Cep-type nature, to detect the pulsational frequencies and to identify most of the degrees of the pulsation modes. All six stars turn out to have frequencies in the expected range for beta Cep stars and the degrees of the main mode range from l =0 up to l=2, which is compatible with theoretical expectations. Based on observations collected with the Swiss Photometric Telescope of the Geneva Observatory situated at La Silla, Chile. Tables~5--10 are only in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5)
