Abstract: We carried out photometric observations of the two bright candidates for Herbig Ae/Be stars HD 35929 and HD 203024 over the period 1993-1996 in the wavelength range 0.3-2.5 µm and high-resolution spectroscopic observations of HD 203024. Small near-infrared excesses were detected in both stars. HD 35929 exhibits light variations at a 0m.2 level. In HD 203024, the optical variability does not exceed 0m.1; its spectrum shows an emission component of the Ha line. Estimates for the fundamental parameters of the stars were obtained: spectral type B9.5 V, color excess EB-V = 0m.20, and a distance of ~300 pc for HD 203024; spectral
type A8 V, EB-V = 0m.15, and a distance of ~100 pc for MD 35929. The two stars are in a late evolutionary stage before the arrival at the main sequence; HD 35929 appears to be more evolved than HD 203024. The latter may belong to the star-forming region 1 Cep.
