New measurements of the distribution of energy in the continuum for eight Be stars in the optical region (3200-7600 A) are presented. The effective temperatures of these stars have been estimated from their observed fluxes. It is found that, in general, pole-on stars show near-infrared excess emission. It is interesting to note that the Balmer jumps for stars having an infrared excess are systematically smaller than for those lacking the infrared excess. Variability of ultraviolet and infrared excess emissions in these stars has been discussed. The stars 59 Cyg, 66 Cyg, 28 omega CMa, and 27 CMa show large variations in their continuum at ultraviolet and infrared regions.
