Ultraviolet spectra of 15 beta Canis Majoris stars in wavelength bands of approximately 100 A around 2100, 2500, and 2800 A (resolution 1.8 A), obtained with the Ultraviolet Stellar Spectrophotometer S 59 on board the ESRO TD-1A satellite are discussed. In general the spectra are similar to those of 'normal' stars, only the star alpha Vir has He I, C II, and Mg II lines slightly weaker than normal. Comparison with theoretical computations shows that the Fe abundance in the beta CMa stars is solar and that the average microturbulent velocity is about 4 km/sec. The UV spectral lines of beta Cep do not show any significant variations in equivalent width with phase.
