The observed absence of late type supergiants with bolometric magnitude less than -9.8 is interpreted in terms of a combined effect of mass loss by stellar wind and overshooting from convective cores. A simple parameter model describing overshooting is developed. With this model, the evolution of massive stars is modeled in such a way that no late type supergiants are formed with bolometric magnitude less than -9.8. This leads to convective cores that are 15-50% larger than when the Schwarzschild criterion is used. It is shown that the derived constraints on the amount of overshooting imply that stars more massive than 33 solar masses evolve into transition WN stars at the end of core hydrogen burning.
