Proper motions have been measured for a color selected sample of stars in a square 4 x 4 deg region centered on the Praesepe open cluster. The magnitude limit of the photometry is about 19 and of the proper motions about 18. A list is presented of 765 probable and possible members from 9 to 18 based on the proper motions, magnitudes, and colors. The results are compared with other proper motion surveys, and a preliminary luminosity function of M(v) = 11 is calculated.
