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.

Here we present the first records of Denheyernaxoides from North America: D. americanus, collected from coniferous litter, soil, and moss in Nova Scotia, Canada. These new records significantly expand the known distribution of the species. Denheyernaxoides americanus is redescribed to include Canadian specimens and to rectify discrepancies in the species’ description identified during examination of the holotype. The deutonymph of D. americanus is also described. Sequences, representing a 658 bp region of the mitochondrial cytochrome c oxidase subunit I (COI), were obtained from representative specimens collected in Canada. Comparison of these sequences with those from the Barcode of Life database (BOLD) suggests that a second species of Denheyernaxoides may occur in British Columbia, Canada. A revised key to world species of Denheyernaxoides is provided.

AbstractEight additional adventive aleocharine beetles, native to the Palaearctic region, are reported from Canada, five of them for the first time. They belong to three tribes: Crataraea suturalis (Mannerheim) (Nova Scotia, Saskatchewan, British Columbia) and “Meotica pallens (Redtenbacher)” (Ontario, British Columbia) belong to Oxypodini; Atheta (Chaetida) longicornis (Gravenhorst) (Nova Scotia, Quebec), Atheta (Thinobaena) vestita (Gravenhorst) (New Brunswick), Dalotia coriaria (Kraatz) (Alberta), Dinaraea angustula (Gyllenhal) (Nova Scotia, Prince Edward Island, Quebec, Alberta), and Nehemitropia lividipennis (Mannerheim) (New Brunswick, Nova Scotia, Prince Edward Island, Quebec, Ontario) belong to Athetini; and Homalota plana (Gyllenhal) (Nova Scotia, New Brunswick) belongs to Homalotini. These species have likely been introduced into Canada from Europe by various anthropogenic activities, and their bionomics and possible modes of introduction are discussed. For each species, a short diagnosis and habitus and genital images are provided to assist with identification. The habitus and genital images are presented here for the first time for these species in North America. New United States records are not included in the abstract.

The spread of Thymelicus lineola (Ochsenheimer) in North America has been extensively documented (Rawson 1931; Clench 1956; Pengelly 1961; Arthur 1966; Burns 1966; McNeil et al. 1975; McNeil and Duchesne 1977). In Canada, T. lineola has been recorded from British Columbia, Ontario, Quebec, New Brunswick, Nova Scotia, Newfoundland, and now Manitoba (Gregory 1975; Jackson 1978). In the north central United States T. lineola has been recorded from St. Louis Co. and International Falls, Minnesota (Brewer 1977; Lundeen 1980). Pengelly (pers. comm.) observed T. lineola at Dryden, Ontario in 1972. McCabe and Post (1977) did not include this species in their list for North Dakota. The purpose of the present note is to report on the presence and collections of T. lineola in Manitoba and in northwestern Ontario.

The minute land snail, Carychium minimum Müller, 1774 is reported from New Brunswick, Canada. This new record further adds additional data to support the supposition that this introduced, European species is probably more widespread over temperate North America than currently known.

The following list of the Coccidæ found to inhabit Canada is complete, so far as the published records show, together with some other information derived from corresponding with Prof. Cockerell, Dr. Fletcher, and Mr. John Dearness. Much, however, has been obtained from material sent to me for identification. In reviewing the list it will be seen that Ontario has 25 species of Coccids credited to her; while Ottawa has 18; Toronto, 6; Quebec, 3; Prince Edward Island, 3; Nova Scotia, 4; New Brunswick, 2; and British Columbia, 6. One has been found in an ants' nest, 8 in greenhouses, and there have been 8 new species described from Canada. There are 46 species, 27 of which are native to North America, 14 are introduced, and 4 whose home is unknown, but which were probably introduced. The large majority of the species have been found by Dr. Fletcher, or at least have passed through his hands. Much credit, however, is due Mr. John Dearness, who has taken great interest in looking for these very injurious insects, and has sent me several very interesting species.
