We present ground-based follow-up photometry in the Geneva seven-colour photometric system of six new {beta} Cep stars. The variability of these objects was originally found from the HIPPARCOS mission. The new data provided here allowed us to confirm their {beta} Cep-type nature, to detect the pulsational frequencies and to identify the degrees of the pulsation modes. For definitions of the Geneva photometric system, see <GCPD/13>.
