Group I

AbstractIps concinnus (Mannerheim) and Ips mexicanus (Hopkins) comprise Group I of the genus Ips DeGeer (Coleoptera: Scolytidae). Members of this group have 3 spines on each lateral margin of the declivity and strongly arcuate sutures on the anterior face of the antennal club. I. radiatae Hopkins is placed as a synonym of I. mexicanus (Hopkins). I. concinnus breeds in Picea sitchensis in the coastal region from Alaska to southern Oregon. I. mexicanus breeds in various species of pines from Alaska to Guatemala and eastward in the United States and Canada to the Rocky Mountains. A key to the species and descriptions are provided.

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.

Working over some neglected material, I found, to my surprise, that the specimens of Ochodœus colleted by me last year in Arizona are separable into three distinct species, none of which agree with the descriptions of the North American species. A few years ago my brother sent me from California, with some other material, two specimens of what I take to be an Ochadœus. Unfortunately, I misplaced one of the specimens, and not wishing to dissect the single remaining one, I leave this species in this genus for the present, till more material is available.

Apical Cells

The genus Gnathodus, as at present accepted, includes forms closely allied to Cicadula, but differing in having only two apical cells in the wing. They are of a weaker build than species of Cicadula, and a characteristic appearance from above makes them readily distinguishable from any of that genus. The species are very variable and difficult to define. They are small, more or less slender, greenish, yellowish, or whitish Jassids, usually without distinct markings. The ocelli are distant from the eyes. The clypeus usually somewhat exceeds the genæ. The ovipositor rarely exceeds the pygofers. In the United States at least, most of the species are of very wide distribution.

A New Species

This work provides a taxonomic survey of the North American species of the genus Elonus Casey, 1895 (Coleoptera: Tenebrionoidea: Aderidae). It includes the description of a new species, Elonus gruberi n. sp. from the United States, related to E. hesperus Werner, 1990 and to E. basalis (LeConte, 1855). A review and key to the North American species is provided.
