This note deals with two European species of Phylini now known to occur in Canada. Both species were discovered in British Columbia some time ago but remained unreported until the present. This report will also provide names for the forthcoming manual of plant bugs of British Columbia and Yukon by L. A. Kelton and G. G. E. Scudder. The two species were probably introduced accidentally into this country with nursery stock. Their identities were confirmed by comparison with named European specimens.

This note deals with four reddish species of European Psallus Fieber known to occur in Canada. Psallus roseus Fabricius was discovered in 1970 in British Columbia, and P. lepidus Fieber and P. jlavellus Stichel were discovered in 1976 in Nova Scotia and are now reported for the first time from the Nearctic region. They were probably introduced accidentally into this country some time ago with nursery stock. The fourth species, P. falleni Reuter, misidentified in North America as P. alnicola Douglas & Scott, is probably naturally Holarctic in distribution. The four species are redescribed, vesicae, left claspers and two adults are illustrated, and a key to separate them is provided.

AbstractOrthops rubricatus (Fallén), a European species now known to occur in North America, is transferred to the genus Pinalitus Kelton. Pinalitus solivagus (Van Duzee) is reported from British Columbia, and P. utahensis Knight and P. brevirostris Knight are considered to be synonyms of it. Pinalitus rostratus n. sp. is described from Canada and western United States. Pinalitus californicus Knight is transferred to the genus Proba Distant. A key to species is provided.

Croesia holmiana (L.) was the most common of nine species of tortricids found in 1977 in a survey of the apple leafrollers of the Vancouver, British Columbia, district. It is an European species not recorded previously from North America. Specimens from British Columbia were identified by Dr. A. Mutuura, Biosystematics Research Institute, Canada Agriculture, Ottawa.

This note deals with three European species of Orthotylinae now known to occur in Canada. Pilophorus confusus was discovered in 1976 in Nova Scotia and is reported for the first time from the Nearctic region. Additional distribution records are given for Orthotylus nassatus and O. viridinervis previously reported from North America by Henry (1977) and Henry and Wheeler (1979), respectively. The three species were likely introduced accidentally into this country some time ago with nursery stock importations but remained undetected until recently. They are predatory and overwinter in the egg stage. The adults of the three species are illustrated.

Our knowledge of the Aphididae of Africa is as yet very limited, this important group of insects having been but little studied, except in Europe and North America. At present only thirty-five species are recorded for the whole African continent, about the number one can collect in a single afternoon in one's own garden in England. It will be noticed that several common European species are recorded, and that they are as destructive in Africa as in Europe, such as the Common Cabbage Aphis (A. brassicae) and the Ribes and Lettuce Aphis (Rhopalosiphum lactucae). Several others occur which have a world-wide distribution, such as the Black Peach Aphis (Aphis persicae), and the Woolly Aphis (Eriosoma lanigerum), doubtless having been distributed on nursery stock, the former as ova and the latter as adults. Fuller has reported destroying and fumigating strawberry plants attacked by Aphis sent from Europe, and Lounsbury records the presence of Apple Aphis eggs on imported stock. Undoubtedly these insects are constantly being distributed from country to country with imported plants, trees and shrubs.

AbstractTwo chalcidoid species, previously known only from Europe, are reported from North America for the first time. Habritys brevicornis (Ratz.) occurs in Quebec, Ontario, and British Columbia. Psilonotus achaeus Wlk. (= Eutelus betulae Grit., new syn.) occurs in Ontario, New York, and Michigan; it parasitizes Oligotrophus betulae Winn. (Cecidomyiidae) in seed of white birch.

The tibiæ are usually all spinose, the eyes naked, the body untufted, the form normal, the male antennæ of various structure, pectinated, brushlike simple. The European species are refered by Lederer all to one genus, Agrotis or Hübner. Nervertheless, I think the yellow-winged forms may well be separated under Hiria and Tryphœna. Of these yellow-winged forms, with flattened abdomen, we have only one T. Chardinyi, from Anticosti and Maine, considered identical with the Siberian species of the same name, described orginally by Boisduval under Anarta.

Abstract. We interpret a suite of satellite, aircraft, and ground-based measurements over the North Pacific Ocean and western North America during April–May 2006 as part of the Intercontinental Chemical Transport Experiment Phase B (INTEX-B) campaign to understand the implications of long-range transport of East Asian emissions to North America. The Canadian component of INTEX-B included 33 vertical profiles from a Cessna 207 aircraft equipped with an aerosol mass spectrometer. Long-range transport of organic aerosols was insignificant, contrary to expectations. Measured sulfate plumes in the free troposphere over British Columbia exceeded 2 μg/m3. We update the global anthropogenic emission inventory in a chemical transport model (GEOS-Chem) and use it to interpret the observations. Aerosol Optical Depth (AOD) retrieved from two satellite instruments (MISR and MODIS) for 2000–2006 are analyzed with GEOS-Chem to estimate an annual growth in Chinese sulfur emissions of 6.2% and 9.6%, respectively. Analysis of aircraft sulfate measurements from the NASA DC-8 over the central Pacific, the NSF C-130 over the east Pacific and the Cessna over British Columbia indicates most Asian sulfate over the ocean is in the lower free troposphere (800–600 hPa), with a decrease in pressure toward land due to orographic effects. We calculate that 56% of the measured sulfate between 500–900 hPa over British Columbia is due to East Asian sources. We find evidence of a 72–85% increase in the relative contribution of East Asian sulfate to the total burden in spring off the northwest coast of the United States since 1985. Campaign-average simulations indicate anthropogenic East Asian sulfur emissions increase mean springtime sulfate in Western Canada at the surface by 0.31 μg/m3 (~30%) and account for 50% of the overall regional sulfate burden between 1 and 5 km. Mean measured daily surface sulfate concentrations taken in the Vancouver area increase by 0.32 μg/m3 per 10% increase in the simulated fraction of Asian sulfate, and suggest current East Asian emissions episodically degrade local air quality by more than 1.5 μg/m3.

AbstractThe genus Japewia Tønsb. is introduced to accommodate three species including J. subaurifera Muhr & Tønsb. sp. nov. based on material from Norway, Sweden, Finland, Scotland, Canada (British Columbia) and U.S.A. (Washington). This species is closely related to Lecidea tornoensis Nyl. but is distinguished in being sorediate and by the production of lobaric acid (accessory) and acetone-soluble pigments. It grows on bark of deciduous and coniferous trees. Lecidea carrollii Coppins & P. James and L. tornoensis Nyl. are transferred to Japewia.
