I find that unless we use neurational characters to separate the genera of Phycidœ, that it will be impossible to classify the species with accuracy. All characters drawn from the periphery, the appendages of the body, will be found subject to very gradual modifications, but I do not think we can afford to reject any of them, because of their relative want of stability. Indeed the neuration in the Lepidoptera seems to be as useful as in the Diptera, although there are certain cases (as I long ago pointed out with regard to Thyridopteryx) where it varies not only in the species, but in the opposite wings of the same specimen. I think that we must regard as generically distinct from Penmpelia the North American species Pravella, which has 8, instead of 7 veins to the hind wings (see Bull. U. S. Geol. Surv. 4, 694). For this species, the structure of which I have quite fully described, I propose the generic name Meroptera. I also find that our two species, found in Texas and Colorado, and which probably mine the Agave, viz., Bollii and Dentata, are distinct from the European types of Zophodia, to which Prof. Zeller referred Bollii, the type of the new genus Megaphycis. In the structure of the palpi, shape of the wings, greater size and length of body, our two large species differ strongly.

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.

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.
