Abstract: Let $ {\mathbb{P}^N}$ be the projective space of all degree $ d$ plane curves and $ V(d,\delta ,\kappa )$ the subvariety of $ {\mathbb{P}^N}$ consisting of all reduced and irreducible curves with $ \delta $ notes and $ \kappa $ cusps. Then $ V(d,\delta ,\kappa )$ is irreducible if $ \kappa \leq \frac{1}{2}(d + 1) - g$.
