While conducting research on the geographic origin of the wheat stem sawfly (Cephus cinctus Norton), we compared North American specimens to specimens of Eurasian Cephus spp., and discovered that specimens currently placed as C. hyalinatus Konow from Siberia are conspecific with the North American species. Given the pest status of the North American populations, which attack wheat and other cereals in the upper Great Plains (Weiss and Morrill 1992), this discovery has important implications for the management of the species. Discussion of these implications will be provided elsewhere (Ivie 1996).

AbstractThe genus Porrhodites Kraatz is redescribed to include the Nearctic Paradeliphrum inflatum Hatch, as well as the Holarctic Porrhodites fenestralis (Zetterstedt). Orochares Kraatz is also redescribed to include Paradeliphrum (new synonymy). In addition to O. angustatus Erichson from Europe, O. japonicus Cameron from Japan and O. villiersi Jarrige from Iran, Orochares now includes two Nearctic species, Paradeliphrum tumidum Hatch from the Pacific Northwest and the new species O. suteri from Illinois and Wisconsin. Keys are provided to distinguish the North American species of each genus, and the major diagnostic characters of all included taxa are illustrated.

AbstractThe North American species of the genus Olophrum Erichson are revised. Seven species are recognized, the holarctic species O. latum Mäklin, O. boreale Gyllenhal, O. consimile Gyllenhal, and O. rotundicolle C. R. Sahlberg; the eastern North American species O. obtectum Erichson, and the new species O. cascadeuse known from northern California and eastern Oregon and O. idahoense known from southern Idaho.Lectotypes are designated for O. marginatum Mäklin (= O. consimile), O. parvulum Mäklin (= O. consimile), O. convexum Mäklin (= O. rotundicolle), and O. convexicolle LeConte (= O. rotundicolle). The following new synonymy was established: O. bernhauerianum Scheerpeltz, O. recticolle Scheerpeltz, O. recticolle curtipenne Scheerpeltz are synonyms of O. consimile; O. quesneli Hatch is a synonym of O. boreale; and O. brevicolle Bernhauer is a synonym of O. latum. All species are described and illustrated with scanning electron photomicrographs and line drawings, five maps showing the North American distribution of each species are provided, and a key is presented to aid in the identification of the species. All available records and biological data for the species are provided.

AbstractThe 10 North American species of Mycetochara Berthold are reviewed. All species are redescribed and one new species, marshalli, is described from California. Former treatments of the species of the genus have considered males and females as separate species. This review associates all known males and females. The following new synonymy is presented: megalops Casey and nigerrima Casey (= fraterna Say); tenuis LeConte, gilipes Casey, and lecontei Borchmann (= foveata LeConte); lugubris LeConte, horni Dury, and davisi Hatch (= analis LeConte); marginata LeConte and longula LeConte (= binotata Say); longipennis Casey (= pubipennis LeConte); and pacifica Casey, nevadensis Casey, crassulipes Casey, downei Hatch, angusta Hatch, malkini Hatch, and caseyi Hatch (= procera Casey).A key is presented to aid in the identification of the species. The male terminalia are illustrated for all species except haldemani and lata, which are known only from females.

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.

The species of this genus have hairy eyes, unarmed tibiæ and a tufted thorax. The dorsum of the abdomen is more or less tufted, but in some species the tuftings are not noticeable. Several species which seem to me to belong to Graphiphora (Taeniocanpa) have been referred to this genus ; among these I may mention orobia of Harvey, modesta, incincta and thecata of Morrison, and the species described by me as rufula and puerilis.

Biological Differences

While investigating the biology of the North American species of Hypomolyx, field workers in Manitoba found a vestigial, or short-winged, and a long-winged form under apparently identical conditions in about equal numbers. Although biological differences were nor then apparent, there was doubt as to whether they were dealing with one dimorphic species or with two distinct species, A search for morphological characters brought to light numerous differences between the two forms, supporting the view that two species were present. These differences, a description the previously unrecognized species, and notes concerning the status of the genera Hylobius and Hypomolyx are reported below.
