Abstract
HD 23194, a member of the Pleiades, was found to pulsate with a period of a bout 30 min. The literature on the star is reviewed, and it is concluded th at it may be a marginal Am star in a binary system. HD 95321 is an evolved Am (rho Puppis) star with a 5.1-h periodicity. Mode identification of its p ulsation, based on multicolour photometry, suggests that the oscillation is probably non-radial with l = 2. We also report on the discovery of six oth er new delta Scuti stars, some of which may be pulsating in gravity modes.
