AbstractThe Nearctic species of the subgenus Anomophagus Reitter of the genus Rhizophagus Herbst are revised. Four taxa are recognized: R. brunneus brunneus Horn 1879, R. brunneus fenyesi Méquignon 1913a, R. pseudobrunneus sp.nov., and R. galbus sp.nov.For the other Nearctic species of the genus, a diagnosis, a type material section, and distributional notes are provided. Two new taxa are described, R. minutus rotundicollis and R. pusillus. Seven specific names are treated as new junior synonyms, namely (with the valid name in parentheses): R. longiceps Casey 1916 and R. rectus Casey 1916 (= R. cylindricus LeConte 1866); R. minutus quadriguttatus Méquignon 1913b (= R. minutus minutus Mmnerheim 1853); R. remotus luteus Méquignon 1913b (= R. remotus LeConte 1866); R. sculpturatus horni Méquignon 1913b (= R. sculpturatus Mannerheim 1852); R. dimidiatus testaceus Méquignon 1913b and R. dimidiatus assimilis Méquignon 1913b (= R. dimidiatus Mannerheim 1843). The subgenera name Syringobidia Casey 1916 (type species: R. cylindricus LeConte 1866) is treated as a new junior subjective synonym of Rhizophagus s.str. A key to all Nearctic species of Rhizophagus is provided with distribution maps of the species.

Conquistator gen. nov., is described to hold the North American species Podisus mucronatus Uhler, 1897. This new genus differs from Podisus Herrich-Schaeffer, 1851, in having the digitiform process on the paramere corpus more characteristic of species in the American asopine genera Apoecilus Stål, 1870 and Supputius Distant, 1889. The new genus, however, also differs from these two genera by essential morphological characters. The type species, Podisus mucronatus Uhler, 1897, is re-described based on a morphological examination of the male and female terminalia.

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.
