Abstract
We study first order local invariants of Vassiliev type for Lagrangian immersions with generic planar caustics. For this we produce some examples of 2-parameter families of Lagrangian maps and study their bifurcation diagrams.

Comments
This paper has been withdrawn because it seems an invariant dual to the D_4 strata is missing. In any case the bifurcation diagrams are correct and the invariants obtained still hold
