The following descriptions of five new genera and species of Tachinidae are based upon material received from several sources as indicated below. Most of the species have been standing in my collection for a number of years pending the accumulation of longer series. My thanks are due A. R. Brooks for the loan of some additional material recently discovered in the extensive tachinid collections in the Canadian Department of Agriculture. The type or paratype specimens, of the two species represented by this material, are returned for deposit in the Canadian Collection, as detailed under the descriptions.

During 1954, I had the opportunity of examining a large collection, circa 3,500 of unidentified Corixidae which had been accumulated in the Canadian Department of Agriculture over a period of years. These notes consist of a list of species identified, with observations where pertinent when these records are new state or country records compared with the full lists of localities given in H. B. Hungerford's ‘The Corixidae of the Western Hemisphere’ 1948, Univ. Kansas Sci. Bull. Vol. XXXII, pp. 1-827.

AbstractThe North American Aegeriidae are revised on the basis of the study of late-instar larvae of about 60 species. These species represent 20 genera in five tribes in two subfamilies: Bembeciini, Zenodoxini, Aegeriini and Melittiini in Zenodoxinae and Synanthedontini in Synanthedontinae. The presently recognized genera, Ramosia Engelhardt, Conopia Hübner and Thamnosphecia Spuler are reduced to synonyms of Synanthedon Hübner. Three new genera are defined by larval characters but are referred to only as Genera I, II and III. Larval characters for most of the species are discussed and illustrated; keys to species, genera and tribes are provided. Tribes, genera and most species are arranged in the text as nearly as possible according to their phylogenetic relationships as suggested by the larvae.

Freshwater Teleosts

Contrary to ideas that Cretaceous fresh waters contained few teleosts, there were several taxa of Esocoidei (pikes and relatives) in North American Cretaceous rivers. Dentaries and palatines of Campanian to Maastrichtian age all have C-shaped tooth bases and other distinctive features of shape and foramina. The fossils include at least three distinct kinds, two of which are described here as new genera and species in the Esocidae: Estesesox foxi n. gen. and sp. and Oldmanesox canadensis n. gen. and sp.These old, diverse, and apparently primitive specimens show that pikes radiated when Eurasia and North America were still joined. Some references in the literature to the Cretaceous fish Platacodon Marsh are based on referred dentaries that are here identified as esocoid fossils. The Esocidae are the first example of a family of Recent North American freshwater teleosts that has been shown to have speciated in Cretaceous fresh waters and survived the terminal Cretaceous extinction.

The World

Since the publication of the writer's “Revision of the Aphelininæ of North America” (Bulletin 1, Technical Series, U. S. Department of Agriculture, Division of Entomology, 1895), the discovery of new forms, and especially of new genera, has been of very infrequent occurence. Species have been received from all parts of the world, owing to the extraordinary and world-wide development of interest in scale insects, which are the principal hosts of the Aphelininæ, yet nearly all of the forms thus received have been species already described, which have been carried with their hosts upon live plants to many different regions. It is, therefore, interesting to discover a new genus, even from a country like Chile, whose parasitic Hymenoptera are so little known. A most interesting feature of the discovery is that the new genus was reared from Aspidiotus hederœ (nerii) together with three of the cosmopolitan forms, namely, Aspidiotiphagus citrinus (Craw); Coccophagus immaculatus, How., and Prospalta aurantii, How. The writer is indebted to Mr. Edwyn C. Reed, of Rancagua, Chile, for this sending, as well as for many other favours.

THE LARVA OF CISSUVORA AMPELOPSIS ENG. AND THE GENERIC POSITION OF PHORADENDRI ENG. (LEPIDOPTERA: AEGERIIDAE)

Generic Position

Footnotes in the larval revision of the North American Aegeriidae (MacKay 1968) indicate that additional material of Cissuvora ampelopsis Engelhardt and [Carmenta] phoradendri Engelhardt was received too late for incorporation in the study. The material consists of a prepupal larva associated with an adult that is posifively identified as Cissuvora ampelopsis and two last-instar larvae believed to be phoradendri, and is discussed in this paper. The study of the material indicates that the unique larva referred to in the 1968 work as “probably Cissuvora ampelopsis” is of an unidentified genus and species, and that the species phoradendri is in Synanthedon rather than in Genus I of the Carmenta group. The larva of the true ampelopsis is described and illustrated here and the characters that key the larvae of phoradendri to Synanthedon are listed.
