  We present the initial results from an in-depth re-examination of the MACHO
project Large Magellanic Cloud database to identify and characterize stellar
variability near the intersection of the instability strip and the main
sequence. This dataset's long time-series and uniform photometry is an
unprecedented resource for describing the frequency and regions of incidence of
various radial and non-radial modes of excitation. The raw MACHO photometry has
been investigated to identify factors responsible for most of the residual
photometric variance and increase the sensitivity to small amplitudes. We
present details of the search method used, the Delta Scuti variables detected
thus far and discuss the implications for the completed survey.
