The north-western European species of the laevigatus-group of Apanteles are revised. Forty species are dealt with, of which twenty are described as new. Brief notes are added on North American species of the group in the British Museum (Nat. Hist.) to assist their eventual correlation with the European species.

AbstractThe north-western European species of the vitripennis, pallipes, octonarius, triangulator, fraternus, formosus, parasitellae, metacarpalis and circumscriptus-groups of Apanteles are revised. Sixty-five species are dealt with, of which twenty-four are described as new. One species, A. exiguus (Haliday), is lifted from synonymy. Brief notes are added on North American species of the circumscriptus-group in the British Museum (Nat. Hist.) to assist their eventual correlation with the European species. Reference is also made to two species of Hypomicrogaster.

While determining a collection of interesting Histeridae taken by the writer and others in Mexico during the past few years, three species were found to belong to the genus Pseudister Bickhardt. As two of these were undescribed, and as one species described from New York and one from Paraguay have been masquerading for many years under a different genus, the following short review is necessary to straighten out the existing confusion. Through the kindness of Dr. K. G. Blair and Dr H. Scott of the British Museum, types of all the species considered in this paper have been examined by the writer.

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.

The North

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.
