We study in this paper local codimension 2 singularities of (first order)\udimplicit differential equations F(x, y, p) = 0, where F is a germ of a smooth function,\udp = dy\uddx , Fp = 0 and Fpp = 0 at the singular point. We obtain topological models of\udthese singularities and deal with their bifurcations in generic 2-parameter families of\udequations
