Study of lonchaeid material reared from cones of various coniferous trees in North America revealed five previously undescribed species of the genus Earomyia Zett. The composite nature of cone-infesting lonchaeidae has not been understood and at least four of the species treated here have been considered as a single species (Keen, 1938, 1952). Much of the material studied, particularly that reared by various Forest Insect Investigations officers of the United States Bureau of Entomology and Plant Quarantine (bearing Hopkins U.S. numbers), has been misidentified as Earomyia viridana (Mg.) (Keen, op. cit.), Lonchaea albitarsis Zett., L. rufitarsis Macq., L. polita Say, and others.

AbstractEight species of Epidamaeus of arctic western North America and extreme northeast, U.S.S.R. are discussed. Two new species, Epidamaeus hammerae and E. tritylos, are proposed and E. arcticolus, E. kodiakensis, E. mackenziensis, E. bakeri, E. coxalis and E. fortispinosus, previously described by Hammer, are redescribed.

Allosaurus is one of the best known theropod dinosaurs from the Jurassic and a crucial taxon in phylogenetic analyses. On the basis of an in-depth, firsthand study of the bulk of Allosaurus specimens housed in North American institutions, we describe here a new theropod dinosaur from the Upper Jurassic Morrison Formation of Western North America, Allosaurus jimmadseni sp. nov., based upon a remarkably complete articulated skeleton and skull and a second specimen with an articulated skull and associated skeleton. The present study also assigns several other specimens to this new species, Allosaurus jimmadseni, which is characterized by a number of autapomorphies present on the dermal skull roof and additional characters present in the postcrania. In particular, whereas the ventral margin of the jugal of Allosaurus fragilis has pronounced sigmoidal convexity, the ventral margin is virtually straight in Allosaurus jimmadseni. The paired nasals of Allosaurus jimmadseni possess bilateral, blade-like crests along the lateral margin, forming a pronounced nasolacrimal crest that is absent in Allosaurus fragilis.

The new species, Stenozonium leonardi, the northernmost representative of the Polyzoniidae in western North America and the only one north of the Columbia River, is described from the Olympic Peninsula of Washington; it is isolated by some 180 mi (288 km) from S. benedictae Shelley, 1998, in coastal Oregon. Stenozonium alone among the four polyzoniidan genera in western North America consists of entirely allopatric and widely separated species, with one apiece in California, Oregon, and Washington-evidence that it diversified earlier than its ordinal counterparts.

A new species, Pholis clemensi, referred to the family Pholidae, is named and described from 12 specimens taken in southern British Columbia waters and the Strait of Juan de Fuca. Pholis clemensi is compared with other members of the genus, and a key is given to the North American species.

The millipede genus Amplaria Chamberlin, 1941 (senior synonym of Vaferaria Causey, 1958 and Speostriaria Causey, 1960) is endemic to western North America, from Mt. Palomar and San Luis Obispo, California, north to southwestern British Columbia, Canada, and east to northern Idaho. Seven species names are currently assigned to the genus. Below I describe ten additional new species: Amplaria crawfordi, Amplaria fontinalis, Amplaria rykkenae, Amplaria arcata, Amplaria baughi, Amplaria staceyi, Amplaria umatilla, Amplaria cervus, Amplaria mendocino and Amplaria flucticulus, and provide new records of Amplaria nazinta Chamberlin.
