Abstract

A new period-amplitude diagram of cepheids has been constructed. The phtoelectric observations of 365 variables were used from which 78 were newly observed. Real differences exist both in the short and in the long period regions of the period-amplitude diagram between the Magellanic Clouds and the Galaxy. It seems there are no significant differences between the upper envelopes derived for M31 and the Galaxy.
