Publications of the United States National Museum The scientific publications of tlie United States National Museum include two series, Proceedings of the United States National Museum and United States National Museum Bulletin. In these series are published original articles and monographs dealing with the collections and work of the Museum and setting forth newly acquired facts in the field of anthroix>logy, biology, geology, history, and technology. Copies of each publication are distributed to libraries and scientific organizations and to specialists and others interested in the various subjects. The Proceedings, begun in 1878, are intended for the publication, in separate form, of shorter papers. These are gathered in volumes, octavo in size, with the publication date of each paper recorded in the table of contents of the volume. In the Bulletin series, the first of which was issued in 1875, appear longer, separate publications consisting of monographs (occasionally in several parts) and volumes in which are collected works on related subjects. Bulletins are either octavo or quarto in size, depending on the needs of the presentation. Since 1902, papers relating to the botanical collections of the Museum have been published in the Bulletin series under the heading Contributions from the United States National Herbarium. This work forms number 270 of the Bulletin series. Frank A. Tayx.or Director, United States National Museum U.S. GOVERNMENT PRINTING OFFICE WASHINGTON : 196S
The Types of Proctotrupoidea (Hymenoptera) in the United States National Museum 1 2 By Lubomir Masner and Carl F.W. Muesebeck There has been increasing activity, in recent years, in the study of the Proctotrupoidea, a very large group of parasitic Hymenoptera, of which the vast majority of species are still undescribed. Several students of the superfamily, particularly in Europe, have been publishing actively on the systematics of the group, and the growing emphasis on biological methods of controlling injurious insects has resulted in an increasing need for reliable identifications. This situation demands a sound under- standing of the groundwork that was laid in the past in order that repeti- tion and confusion may be avoided. The publication of a list of the described genera and subgenera of Proctotrupoidea, with citation of their type-species (Muesebeck and Walkley, 1956), has helped to define the genera and subgenera of this group and to bring about uniformity in the application of these names. Another fundamental and essential step is the establishment of the identity of the described species. The type series of some species con- sists of two or more different forms, and the original author has often failed to designate a holotype.lt has become advisable, therefore, to re- view the case for each species and, where necessary, to designate a lectotype as the standard for the species. Unfortunately, the types of species described by some authors, notably Kieffer, have become widely scattered or lost, but large type collections of Proctotrupoidea occur in certain institutions, particularly in the British Museum (Natural History) and the United States National Museum. The senior author studied the proctotrupoid types in the British Museum and in the Hope Department of Entomology at Oxford in 1961 and subsequently (Masner, 1965) published a list of these with appropriate lectotype designations where such ac- tion was required. Under a grant from the National Institutes of Health, he spent several months of 1964 in study of the types of Proctotrupoidea Czechoslovak Academy of Sciences, Prague. U.S. National Museum.
