Ser. 108 595 1994 1994A&AS..108..595C stars: chemically peculiar stars: variables: other In the framework of a programme of checking the periods of chemically peculiar stars, eight southern stars have been observed in the uvby system. Seven stars have been previously known to be light variables, but for some stars the periods were not accurate enough to phase together different kinds of observations carried out several years apart. The periods of HD 83368, HD 98088, and HD 153882 are confirmed. For the stars HD 49976, HD 111133, HD 118022, and HD 164258 we present here more refined values of the period. No variability has been detected for the star HD 137949 within a time scale of the order of ten days.
