The types of 23 nominal species of Diapriidae (Ambositrinae and Ismarinae), Heloridae, Monomachidae and Proctotrupidae, in the collection of the Muséum national d’Histoire naturelle, Paris, are catalogued. Lectotypes are designated for two taxa (Serphus (Phaenoserphus) micrurus Kieffer, 1908 and S. (P.) viator var. testaceicornis Kieffer, 1908) and some previous lectotype designations are reviewed. Proctotrupes indivisus (Kieffer, 1908) is removed from synonymy with P. gravidator (Linnaeus, 1758). Brief notes are provided on the history of the insect collection of Louis Augustin Guillaume Bosc d’Antic.
