The systematic position of the genus Massalongia and the closely related genera Koerberia, Vestergrenopsis, and Placynthium in the family Peltigeraceae including lichens with hemiangiocarpic apothecia is discussed. The ontogeny of a hemiangiocarpic apothecium is described briefly. A key for the determination of the genera is provided.A general survey is given for the morphology and anatomy of the genus Massalongia. The two species, M. carnosa and M. microphylliza, are described in detail. The new combination M. microphylliza is made.

AbstractThe systematic position of the North American species described, originally, in the genus Trioxys Haliday is discussed. The following nine taxa are of genus Trioxys sensu strictu: T. (Trioxys) ameraceris Smith, betulae Marshall, new RECORD, bonnevillensis Smith, exareolatus (Viereck), gahani Smith, ibis Mackauer, NEW RECORD, infrequens Smith, utilis Muesebeck; and T. (Betuloxys) compressicornis Ruthe, NEW RECORD. Six species fall into genus Binodoxys Mackauer: B. carolinensis (Smith), coruscanigrans (Gahan), cupressicola (Gahan), NEW COMB., nearctaphidisN. SP., palmerae (Smith), and rhagii (Ashmead).

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.

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.
