Abstract: We analyse photometric data, gathered during several years, of seven B-type variable stars that were previously discussed by Waelkens and Rufener (1985). It is found that all these stars are multiperiodic variables with periods of the order of days. For HD 177863, two periods could be identified, for HD 74560 and HD 181558 three periods, for HD 123515 four periods, for HD 74195 five periods, for HD 143309 six periods, and for HD 160124 eight periods. For all stars and all modes, a same dependence of the amplitude on wavelength is found, with amplitudes in the U-bands about twice as large as in the V-band.
