We used restriction fragment analysis of chloroplast, nuclear, and mitochondrial DNA to study phylogeny in the genus Pseudotsuga. Total genomic DNA from one outgroup (Larix occidentalis Nutt.) and five Pseudotsuga species from Japan, mainland China, Taiwan, and North America were digested with 20 restriction enzymes, blotted, and probed up to 17 times with cloned DNA fragments. A total of 38 shared fragment characters were subjected to Wagner parsimony analysis coupled with bootstrapping to evaluate statistical significance of the phylogenetic trees. The complex patterns that we observed for actin gene fragments were evaluated via a Fitch–Margoliash distance-matrix analysis. Both parsimony and distance-matrix analyses indicated that relationships among species in the genus coincide with their current geographic distribution; genetic similarity declines with migration distance around the Pacific Rim. The Asian and North American species form well-differentiated and statistically significant monophyletic groups. Pseudotsuga japonica is the Asian species closest to the North American species. Affinities to the outgroup Larix occidentalis suggest that Pseudotsuga originated in North America and then migrated into Asia. Key words: parsimony, phylogeny, biogeography, conifer, Pinaceae.

AbstractIps calligraphus (Germar), I. ponderosae Swaine and I. interstitialis (Eichhoff) represent one variable species with the oldest name, Ips calligraphus (Germar) taking precedence. Ips calligraphus can always be recognized by the six spines on each side of the declivity. All other species in North America have less than six spines on each side.

AbstractThe genus Ips is one of four closely related genera in the tribe Ipini, sub-tribe Ipina (De Geer 1775, Balachowsky 1949, Nunberg 1954, Hopping 1963). There are now 32 species of Ips recognized in North America, with a few more as yet undescribed. This paper defines the groups of closely related species with observations on the group relationships of species from other parts of the world. Work is in progress to define the North American species in each group.

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.

New distributional records, new larval host records, various collecting notes, and observations are reported for the North American species of the tribe Agallissini LeConte, 1873 (Coleoptera: Cerambycidae: Cerambycinae): Agallissus lepturoides (Duponchel & Chevrolat, 1841), Osmopleura chamaeropis (Horn, 1893), and Zagymnus clerinus (LeConte, 1873). The species are illustrated and distribution maps are provided.

The following nomenclatural changes to the genus Phymatodes Mulsant, 1839 are proposed: P. juglandis Leng, 1890 = P. decussatus (LeConte, 1857); P. mohavensis Linsley and Chemsak, 1963 = P. nitidus LeConte, 1874; P. lecontei Linsley, 1938 (a replacement name) = P. grandis Casey, 1912; P. oregonensis Chemsak, 1963 = P. nigrescens Hardy and Preece, 1927; P. blandus picipes Linsley, 1934 and P. blandus propinquus Linsley, 1934 = P. blandus (LeConte, 1859); P. hirtellus densipennis Casey, 1912 and P. ursae Knull, 1940 = P. hirtellus (LeConte, 1873); P. decussatus australis Chemsak, 1963 and P. decussatus posticus Van Dyke, 1920 = P. obliquus Casey, 1891; P. frosti Casey, 1924, a valid name which has not previously been mentioned in the literature = P. dimidiatus (Kirby in Richardson, 1837); P. concolor Linsley, 1934 is afforded full species status; P. lividus (Rossi, 1794) is formally recorded as established in North America. A key and diagnoses for all native and introduced North American species are provided, which include the more recently described species, P. tysoni Linsley and Chemsak, 1984, and P. shareeae Cope, 1984, in addition to the introduced species P. lividus.

The Byrrhidæ of this continent have received a comparatively small share of attention at the hands of systematists for many years, so that it is not at all surprising to find novelties among recently-collected material. Two new forms of the genus Pedilophorus have recently been detected among the accumulations in my cabinet, both of them from the west; no doubt still others remain to reward explorers of the mountain ranges and of the northern districts. The European fauna contains ten species, while but four were previously known from North America.

Most works about Climaciella brunnea (Say) deal with predation and parasitoidism on wolf spiders (Lycosidae), or records of populations that mimic vespid wasps (Polistes spp.). Knowledge on immature mantispids is scarce, particularly about pupae. Currently, a key by Hoffman and Brushwein provides information on larvae and pupae of several North American species. Herein, the pupa of C. brunnea is described for the first time, on the basis of a specimen from central Mexico, and its position in the available key is proposed,. The pupa of Plega yucatanae Parker & Stange from southeastern Mexico is also incorporated to the key on the basis of a published description.
