Abstract Data concerning the positions, photometry, proper motions, and radial velocities have been compiled for a sample of Ap and Bp stars toward the Scorpius-Centaurus association. Probable members of the association are identified, and new magnetic observations of 13 of these member Ap stars in the mass range 2.5-4.5 solar masses are presented. These magnetic observations are compared with similar data for a sample of old field Ap stars. No evidence is found for a significant difference between the distributions of magnetic field strengths of the two samples, suggesting that little or no evolution of the magnetic fields in Ap stars occurs on a time scale of a few x 10 to the 8th yr.
