Abstract

The authors describe the search for {delta} Scuti stars in the MACHO database of bulge fields. Concentrating on a sample of high amplitude {delta} Scutis, they examine the light curves and pulsation modes. They also discuss their spatial distribution and evolutionary status using mean colors and absolute magnitudes
