Abstract: The phenomenon of Double Periodic Variables is summarized, with special attention to their photometric and spectroscopic fingerprints. In all well-studied cases the orbital light curve can be modeled with a B-type star surrounded by a dense disk-like envelope and a cooler donor (spectral types B, A, F, G) filling its Roche lobe. The study of V393 Scorpii provides clues on the evolutionary stage of these variables, and suggests that a bi-polar wind is responsible for the long-cycle variability. It is argued that Double Periodic Variables could be progenitors of some Be stars.
