The 1038 primary types (holotypes and lectotypes) of the neotropical and nearctic Notodontidae (excluding the Dioptinae), at the National Museum of Natural History in Washington, D.C. (USNM) represents the largest single collection of notodontid types from the New World. These are compiled to a type catalogue in alphabetical order. An additional 34 primary types of Palaearctic and Oriental Notodontidae are assembled and illustrated in a separate chapter. This catalogue provides the original combination with full reference, the type material according to the original description, the type locality and the current status of the taxon. From syntype series 733 lectotypes are designated to stabilize the nomenclature. One of them is deposited at BMNH, all other are in the holdings of USNM. The types of 54 species, including three types of infrasubspecific taxa, were not traced. The adults of all traced primary types and some paralectotypes – 1292 figures – are illustrated in natural size and in colour. The corresponding genitalia preparations of 97 slides primary types are also figured. The type localities in Central and South American are tabulated with approximate geographical coordinates and also current place names and presented in two maps. Rifargia morula Dognin, 1914 is recognized here as a junior synonym of Rifargia mortis Schaus, 1905 (syn. nov.). Pydna adjutrea Schaus, 1928, placed as a junior synonym of Torona ferrifera Walker, 1865, by Kiriakoff, 1962: 203, is a bona fide species and elevated to species rank: Bireta (Torona) adjutrea (Schaus, 1928) rev. stat.
