Beamer of the University of Kansas under whose direction this work was performed, and to Dr. P. W. Oman of the Division of Insect Identification of the United States Department of Agriculture who was constantly in touch with the progress of the work, who made numerous helpful suggestions, who was most hospitable to the writer during a visit to Washington, D. C, and who loaned Plate 1 for use in this work. The entire staff of the Department of Entomology of the University of Kansas have taken a keen interest in the development of the work, and have discussed several phases of the problem with the writer, often making useful suggestions.

The University of Chicago Press is collaborating with JSTOR to digitize, preserve and extend access to International Journal of Plant Sciences.Rhus L. (sensu lato) has been considered the largest and most widespread genus in the Anacardiaceae. Controversy has surrounded the delimitation of the genus. Historically, seven segregate genera have been recognized: Actinocheita, Cotinus, Malosma, Melanococca, Metopium, Searsia, and Toxicodendron. These genera, together with Rhus s.str., are commonly referred to as the Rhus complex. Rhus s.str. includes two subgenera, Lobadium (ca. 25 spp.) and Rhus (ca. 10 spp.). Sequences of the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA were employed to examine the monophyly of Rhus s.str. and to provide insight into the phylogenetic and biogeographic history of the genus. The ITS data set indicates that Rhus s.str. is monophyletic. Actinocheita, Cotinus, Malosma, Searsia, and Toxicodendron are distinct from Rhus s.str., although the relationships among these genera of the Rhus complex are not well resolved. Rhus subgenus Rhus is paraphyletic; the monophyletic subgenus Lobadium is nested within it. The ITS data set indicates that, for Rhus, the Madro-Tertiary floristic element (subgenus Lobadium) had a single origin within the ArctoTertiary floristic element (subgenus Rhus).

We report the first discovery since the 1970s of a new extant family (Aenigmatineidae fam.n.) of homoneurous moths, based on the small Aenigmatinea glatzella sp.n. from Kangaroo Island off southern Australia. It exhibits a combination of extraordinary anatomical characters, and, unlike most homoneurous moths, its larva is a conifer‐feeder (stem mining in Callitris, Cupressaceae). While the adult's mouthparts are strongly regressed, evidence from other morphological characters and from a Bayesian analysis of 25 genetic loci convincingly places the taxon among Glossata (‘tongue moths’). An unexpected tongue moth clade including Acanthopteroctetidae and Neopseustidae, suggested with low support in recent molecular analyses, remarkably becomes strongly supported when Aenigmatinea is included in the molecular analysis; the new taxon becomes subordinated in that clade (as sister group to Neopseustidae) and the clade itself appears as the sister group of all Heteroneura, representing the vast majority of all Lepidoptera. Including Aenigmatinea into the analysis thereby strengthens the surprising indication of non‐monophyly of Myoglossata, and the new phylogeny requires an additional number of ad hoc assumptions of convergence/character reversals in early Lepidoptera evolution.

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 v/as 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. Acknowledgments. -^T he progress of this work has been aided by so
