Six North American species of leafhoppers of the genus Aphrodes were listed, with 36 synonyms, by Oman (1949). Examination of the male genitalia has revealed not more than four species. Because of the extensive individual variation it is often difficult to identify some of the species on external characters alone. The male genitalia, however, show good specific characters (Figs. 1-5).

A New Species

Species of Balcluthini show great similarity in external appearance and many exhibit much individual variation. Examination of the male genitalia is the only certain means of identification. Baker (1896, Can. Ent. 28: 35-42) attempted to separate the species on external characters, and Davidson and DeLong (1935, Proc. Ent. Soc. Wash. 37: 97-112) revised the North American species and figured the male genitalia. Little has been published on the species occurring in Canada. Five species from Canada are represented in the Canadian National Collection. One of them is previously undescribed.

AbstractThe North American species of Lauxania Latreille are revised. The genus contains five Nearctic species: L. albiseta Coquillett, L. glabrifronssp.nov., L. kafaristasp.nov., L. nigrimana Coquillett, and L. shewellisp.nov. All Nearctic species are illustrated and keyed. Consistent genitalic differences between Nearctic and Palaearctic specimens of the species usually identified as Lauxania cylindricornis (Fabricius) justify the recognition of the Nearctic specimens as a distinct species (L. shewelli). The male genitalia of Lauxania represent two types: the apparently plesiomorphic type has a simple rodlike phallapodeme, membranous phallus, and pointed unbranched postgonites; the apomorphic type has the phallapodeme expanded into a sclerotized hood surrounding the base of the phallus, a convoluted sclerotized phallus, and branched postgonites. These two genitalic types also occur in the related genus Calliopum Strand, which provides strong evidence that these genera, as currently recognized, may not be monophyletic relative to one another.

A REVIEW OF THE NORTH AMERICAN SPECIES OF GONIA sens. lat. (DIPTERA, TACHINIDAE)

The present sunmary of Gonia sens. lat. is made necessary because of a large number of undescribcd species recently segregated in the Canadian National Collection and by Dr. H. J. Reinhard. The group covered is the same as that summarized by Tothil (1924) and Morrison (1940), the latter work containing all records of species up until 1940 and with illustrations of the male genitalia of each species. It becomes only necessary then to present descriptions of new species and to fit all species into their proper restricted genera (in Townsend's sense): a key to all described North American species and illustrations of the new species are included.

The following stucly is based on the material in the Canadian National Collection supplemented by specimens from the collections of Messrs. Carl G. Siepmann, F. S. Carr, and G. Stace Smith. No new characters for the separation of closely allied species are offered in this paper. The most valuable characters known are those of the so-called flagellum of the male genitalia; the most useful for key purposes are presented by the elytral markings.

AbstractNine new species of Slaterocoris Wagner are described from North America: pilosus from British Columbia; alpinus from Colorado; apache from Arizona, Colorado, and Utah; flavipes, solidaginis, and sparsus from California; argenteus, grandis, and simplex from Durango, Mexico. The other species in the genus are: ambrosiae (Kngt.), atratus (Uhl.), atritibialis (Kngt.), breviatus (Kngt.), croceipes (Uhl.), hirtus (Kngt.), longipennis Kngt., mohri (Kngt.), pallidicornis (Kngt.), pallipes (Kngt.). robustus (Uhl.), rubrofemoratus Kngt., sheridani Kngt., stygicus (Say), and utahensis Kngt. Strongylocoris uniformis Van D. is placed in synonymy with Stiphrosoma robusta Uhl. Strongylocoris albibasis Knight does not belong to Slaterocoris and will be dealt with in a subsequent paper. All species are keyed and the male genitalia illustrated.

AbstractGroup VII of North American Ips contains I. thomasi, new species, I. borealis Swaine and I. swainei R. Hopping. They are less than 4.0 mm. long and females have the front of the head or at least the vertex smooth and shining, impunctate, or with very fine sparse punctures; males are more coarsely granulate-punctate on the frons. The species are described and a key is given. All breed in Picea in Canada and northern United States.

As noted below the two North American species described in Syndipnus by workers appear to belong in other genrra. In Europe the gunus is represented by nearly a score of species and has been reviewed in recent years by two writers (1, 2). North American collections contain very few representatives of the genus; after combining the material in the National Collection with that from the United States National Museum, the latter kindly loaned to me by Mr. R. A. Cushman, only thirty-seven specimens are available for study.
