Abstract. First order Lagrangian densities on the bundle of connections
of a principal bundle invariant under the full Lie algebra of the
infinitesimal automorphisms of the principal bundle are classified.
Keywords. Bundle of connections, infinitesimal automorphism of a
principal bundle, invariant Lagrangian densities.
