Abstract
An alternative way of introducing the supersymmetric cosmological term in a supergravity theory is presented. We show that the -Lorentz superalgebra allows to construct a geometrical formulation of supergravity containing a generalized supersymmetric cosmological constant. The , supergravity action is built only from the curvatures of the -Lorentz superalgebra and corresponds to a MacDowell-Mansouri like action. The extension to a generalized -Lorentz superalgebra is also analyzed.
