Kelley's solution for the incompressible viscous flow past an infinite wall, with time dependent suction, is extended for an idealized elastico-viscous liquid. The effect of the presence of the elasticity on the velocity field and the skin friction is examined. It is found that the back-flow at the wall is enhanced by the elasticity parameter. The phase angle of the skin friction is also found to decrease with increasing the unsteady part of the suction velocity.
