Scientific paper

Light variations have been discovered in four B2 V and B3 IV stars. The
periods are an hour or less, and the ranges are from 0.015 to 0.025 mag.
The properties of these variables are discussed and compared with those
of the Beta Cephei stars and those of Eggen's (1970) zero-age
ultrashort-period Delta Scuti stars.
