Optical region spectrophotometry of nine magnetic Ap stars is presented. A new scan of HD 10783 better defines the λ5200 feature profile as it has more values than previous scans. For the large amplitude variables 56 Tauri and HD 184905, scans at different parts of their cycles reveal large changes in the sizes of their Balmer jumps relative to those in their Paschen continua. HD 43819 and 49 Cam have energy distributions similar to other Ap stars in their color temperature domains. 53 Aurigae, HD 64486, and HD 147550 are found to be spectrophotometric mild Ap stars. Observations of HD 192913 about its cycle of variability show that the size of the Balmer jump and the λ4200 feature vary together.
