A spectral classification of select Delta Scuti stars is carried out. It is noted that although the new spectral types assigned differ from those of previous spectral classification, they are consistent with the location of the stars in both the H-R diagram and the period-luminosity-color-relation (PLCR). It is acknowledged that the spectral types of the stars may be variable. Although the stars dealt with are variable, the variations are small enough so that the pulsation changes are masked by the low dispersion utilized (125 A/mm). Longer-period variations are not considered. Spectrograms of the spectroscopic standards HR 2852 and HR 1279 are included, as are spectrograms of some of the Delta Scuti stars.
