We present color magnitude diagrams of four blue massive and compact starclusters in M31: G38, G44, G94, and G293. The diagrams of the four clustersreveal a well-populated upper main sequence and various numbers of supergiants.The U-B and B-V colors of the upper main sequence stars are used to determinereddening estimates of the different lines of sight in the M31 disk. Reddeningvalues range from E(B-V) = 0.20 +/- 0.10 to 0.31 +/- 0.11. We statisticallyremove field stars on the basis of completeness, magnitude and color. Isochronefits to the field-subtracted, reddening-corrected diagrams yield age estimatesranging from 63 +/- 15 Myr to 160 +/- 60 Myr. Implications for the recentevolution of the disk near NGC 206 are discussed.Comment: 17 pages, Latex, ApJ, in Pres
