Results of an X-ray survey of Beta Cephei stars are reported. Three of the six surveyed Beta Cephei stars are detected with an X-ray luminosity (LX) lying in the range (0.8 - 4.2)×1031 erg s-1. The mean value of the ratio of X-ray luminosity to bolometric luminosity (LX/Lbol) for the Beta Cephei stars, including three from an earlier survey, is found to be 8.6×10-8. No dependence of LX or LX/Lbol is found on the binary or short pulsation periods of the observed stars. Likewise no correlation was found between LX and the rotation velocity of the Beta Cephei stars. It is concluded that X-ray characteristics of Beta Cephei stars are indistinguishable from other B stars of similar luminosity class. There is an indication of X-ray flux variations by a factor of ≡2 on a time-scale of about 10 min from β CMa. Implications of the results are briefly discussed in terms of models of X-ray emission from early type stars.
