All referrals during the year 1977 to the only child psychiatric facility in the Province of Newfoundland and Labrador were investigated on a number of variables. Two hundred and two children were referred. This was considered a very low rate of referrals. Distance of the child's residence beyond the range of 50 kilometres from the unit was negatively associated to referrals. Lack of parental employment was not associated with increased rate of referrals. Children from the outlying regions of the Province were unlikely to come from broken families. Academic failure was common among those referred. Few differences were observed in the clinical diagnoses between those referred from the Avalon Peninsula and the regions lying further away. As compared to another Canadian province, Ontario, (Ottawa-Carleton region) (2), fewer aggressive children were referred in Newfoundland. Some implications of these findings for the practice of child psychiatry in the Province were discussed.

Highly pathogenic avian influenza (HPAI) viruses of the A/Goose/Guangdong/1/1996 lineage (GsGd), which threaten the health of poultry, wildlife and humans, are spreading across Asia, Europe and Africa, but are currently absent from Oceania and the Americas. In December 2021, H5N1 HPAI viruses were detected in poultry and a free-living gull in St. John, Newfoundland and Labrador, Canada. Phylogenetic analysis showed that these viruses were most closely related to HPAI GsGd viruses circulating in northwestern Europe in spring 2021. Analysis of wild bird migration suggested that these viruses may have been carried across the Atlantic via Iceland, Greenland/Arctic or pelagic routes. The here documented incursion of HPAI GsGd viruses into North America raises concern for further virus spread across the Americas by wild bird migration.

_ The most easterly point of North America was the setting for the 11th International Symposium on Novel Aromatic Compounds (ISNA-11), which took place on 14-18 August 2005 in the picturesque harbor city of St. John's, Newfoundland and Labrador, Canada. An atypically small, but nevertheless enthusiastic, group of 135 delegates representing 17 countries and 64 academic and industrial institutions participated in ISNA-11. The scientific program consisted of 107 posters (two sessions), 26 plenary lectures, and the Nozoe lecture, which was presented by Prof. Koichi Komatsu of Kyoto University.The inaugural ISNA meeting was held in Sendai, Japan in 1970. Since then, ISNA meetings have been held at three- to four-year intervals at locations that cycle between Asia, North America, and Europe. In its infancy, the ISNA community was focused primarily on the definition and quantification of aromaticity, as well as the synthesis and study of compounds that exhibited the phenomenon, whatever it may be. Nourished by advances in synthetic methodology, analytical techniques, separation capabilities, and computational power, ISNA has blossomed over the intervening 35 years to embody a much broader and deeper set of interests. In particular, the twin issues of function and applications have emerged as integral components of ISNA's collective being.The scientific topics of ISNA-11 were selected with an eye toward balancing the traditional areas of interest with its expansion in new directions. The 15 articles that appear in this issue embody these themes, which include:the synthesis of aromatic compoundstheoretically interesting aromatic moleculesstructural aspects of aromaticityaromatic compounds for devicesfullerenes and nanotubesmolecular switches and machinesmacrocyclic aromatic compoundsDebate about the status and future direction of ISNA was actively encouraged, and the overwhelming response was that ISNA is more vibrant and relevant than ever before. It is healthy and growing in many ways. It was therefore decided to move subsequent ISNA meetings to a two-year cycle. This will commence with ISNA-12, which will be held on Awaji Island (located near Kobe) in Japan on 22-27 July 2007. Professor Yoshito Tobe (Osaka University) will serve as conference chair. The responsibility for ISNA-13 was also awarded. It will be organized by Prof. François Diederich (ETH Zürich) and will be held at a yet to be determined European location in 2009.Graham BodwellRik TykwinskiConference Editors

First collected in North America in 1937 on the Avalon Peninsula of the Island of Newfoundland, the introduced, primarily European land snail, Discus rotundatus, has now been recorded from the Island of Newfoundland, Nova Scotia, New Brunswick, Quebec, Ontario, and British Columbia. We review all known records from Canada, demonstrate that D. rotundatus is more widespread than was previously recognized on the Island of Newfoundland, and report the first record from New Brunswick.

Archaeocyaths of the class Regulares have been discovered in the Devils Cove Member of the Forteau Formation in eastern and southern parts of western Newfoundland. The three species recovered are the first Regulares reported from the northern Appalachians, all archaeocyaths from the bioherms and biostromes to the west and north in Newfoundland and Labrador are Irregulares. This sparse, but well-preserved fauna is similar to the poorly-preserved fauna from the central and southern Appalachians, as well as the abundant and diverse Regulares fauna from the Cordillera, but unlike contemporaneous asiatic and australoantarctic faunas, lending support to the view that late Lower Cambrian archaeocyaths in North America were endemic.

A checklist of 1246 extant, described species, classified in 346 genera in 18 families of Chalcidoidea (Hymenoptera) are reported from Canada, Alaska (USA) and Greenland (Denmark) based on examined specimens and published records up to December 31, 2020. Of the reported species, 1214 (in 345 genera in 18 families) are listed from Canada, 113 (in 58 genera in 10 families) from Alaska, and 26 (in 22 genera in 4 families) from Greenland. The list includes 235 new species records and 53 new generic records for Canada (no new family records). Forty-one new species records, 22 new generic records and the families Chalcididae and Eurytomidae are newly reported for Alaska. No new records were found for Greenland. Two species (in one genus) of Mymarommatoidea are reported from Canada. For each species in Canada, distribution is tabulated by province or territory, except the province of Newfoundland and Labrador is divided into the island of Newfoundland and the region of Labrador. The inclusion of known species from Alaska and Greenland results in the first comprehensive distributional checklist for the entire northern part of the Nearctic region. A brief review of the history of cataloguing Chalcidoidea in North America and a comparison of this checklist with four published checklists from the Palaearctic region is provided.

Avalon Peninsula

In 1958 I reported finding the European geometrid moth Perizoma alchemillata (L.) on the Avalon Peninsula of Newfoundland. This yas based on seven specimens collected in 1954 in the general vicinity of St. John's, but in places several miles apart, suggesting that the species was already well established. That was the first record of this species for North America. Morris and Bolte (1977) discussed its further spread in Newfoundland, summarized what was known about its food plants and distribution elsewhere, and gave illustrations of adults and genitalia. By 1975 it had become common on the Avalon Peninsula and was known from Lethbridge in central Newfoundland and Tompkins in western Newfoundland. Eleven adults were collected at Tompkins, 2-31 July 1975. Morris (1980: 241; pl. 29, fig. 26) again treated this species, adding Stephenville and St. Georges to the list of localities, indicating that additional material had been collected in southwest Newfoundland between 1975 and 1980. In 1959 and 1962 I collected intensively in the region of the Codroy Valley in southwest Newfoundland, covering the season from June to mid-August, and found no indication of its presence then; nor did I see it in a large collection made by Akira Mutuura in the Codroy Valley in July 1968 (Canadian National Collection).

Ornithophilic vectors of avian hematozoa on the Avalon Peninsula, Newfoundland, were determined to be Simulium latipes and S. aureum for Leucocytozoon, Culicoides stilobezzioides for Haemoproteus, and possibly, on circumstantial evidence, Aedes punctor for Plasmodium. Simuliids and ceratopogonids were captured following attraction to bird bait most frequently at heights of 3–4 m in the forest canopy, in the evening, during July and August. Vector density was extremely low when compared to elsewhere in North America, but the highly efficient host–vector–parasite relationship maintained a high prevalence of blood parasites in the bird population.
