Amischa tersa Casey is recorded from Canada and the Yukon for the first time. Twenty-four new records of aleocharine species from the Yukon are provided in addition to species described as new to science. One hundred and fifteen digital images of external and genital structures are provided for species identification.

A comprehensive species review of the genera Gyrophaena Mannerheim and Eumicrota Casey is presented for New Brunswick, Canada. Twenty-four species of Gyrophaena are reported from New Brunswick including two new species, and two species of Eumicrota. Nineteen previously described species are newly recorded in New Brunswick, eight of which are newly reported in Canada. New species are: Gyrophaena meduxnekeagensis Klimaszewski & Webster, sp. n., and G. pseudocriddlei Klimaszewski & Webster, sp. n. New Canadian records are: G. chippewa Seevers, G. corruscula Erichson, G. dybasi Seevers, G. fuscicollis Casey, G. illiana Seevers, G. involuta Casey, G. laetula Casey, and G. lobata Casey. New records for New Brunswick: G. fuscicollis Casey, G. caseyi Seevers, G. chippewa Seevers, E. corruscula Erichson, G. criddlei Casey, G. dybasi Seevers, G. fl avicornis Melsheimer, G. gaudens Casey, G. gilvicollis Casey, G. gracilis Seevers, G. illiana Seevers, G. involuta Casey, G. laetula Casey, G. lobata Casey, G. sculptipennis Casey, E. socia (Erichson), G. subnitens Casey, G. uteana Casey, and G. vitrina Casey. All species are documented by colour habitus images, black/white images of genital structures, and distributional maps. All female genital structures are presented and illustrated here for the fi rst time. A key to the New Brunswick species is provided.

Pachybrachis (Coleoptera, Chrysomelidae, Cryptocephalinae) of Eastern Canada.

Abstract Seventeen Pachybrachis species occurring in eastern Canada [Ontario (ON), Québec (QC), New Brunswick (NB), Nova Scotia (NS), and Prince Edward Island (PE)] are treated by the authors. Two new national records were discovered, both from southernmost Ontario: P. cephalicus Fall and P. luctuosus Suffrian. Four species were new provincial records: P. cephalicus (ON), P. luctuosus (ON, QC), P. obsoletus Suffrian (NB), P. peccans (PE). A fully illustrated key to the Pachybrachis of eastern Canada is provided and supported with extensive photographs, distribution maps, and plant associations. Three species were distributed from southern Ontario into at least one province in the Maritimes (P. nigricornis (Say), P. obsoletus Suffrianand P. peccans Suffrian). Six species were distributed along the shores of the Great Lakes (Erie, Michigan, and Ontario) and rivers (Ottawa, Saguenay and St. Lawrence), but unknown from central and northern ON and QC (P. bivittatus (Say), P. hepaticus hepaticus (F. E. Melsheimer), P. othonus othonus (Say), P. pectoralis (F. E. Melsheimer), P. spumarius Suffrianand P. trinotatus (F. E. Melsheimer)). Seven species were rare, five being found exclusively from southern ON (P. calcaratus Fall, P. cephalicus, P. luridus (Fabricius), P. subfasciatus (J. E. LeConte)and P. tridens (F. E. Melsheimer)), with two having, in addition, a disjunct population in QC (P. atomarius (F. E. Melsheimer)and P. luctuosus). One species was found to be the northern most extension of an eastern United States (US) distribution into the eastern townships of QC (P. m-nigrum (F. E. Melsheimer)). There were no Pachybrachis that could be considered arctic, subarctic, or boreal species; no specimens were found from Labrador and Newfoundland, and all species had southern affinities. Pachybrachis atomarius, P. calcaratus, P. luridus, P. subfaciatus, and P. tridens, not seen over the last 30–70 years, may be extirpated from eastern Canada.

Potential indicator species of climate changes occurring in Québec, Part 1: the small brown lacewing fly Micromus posticus (Walker) (Neuroptera: Hemerobiidae)

Abstract Micromus posticus (Walker) is a small brown lacewing fly rarely collected in Canada and represented in collections by only a limited number of specimens. Indeed, fewer than 50 specimens were captured in Québec and Ontario over the last century, all within a small area delimited by the northern shore of Lake Erie, Ottawa and Montréal. Aylmer, located on the north shore of the Ottawa River, northwest of Ottawa, is a new, most southwestern locality record of this species for Québec. The Aylmer specimens were collected 1-7 days later than any of the known specimens collected elsewhere in Québec or in Ontario, and 16-22 days later than in the neighbouring localities, indicating an apparent phenological shift.

First Record of the European Rusted Flea Beetle, Neocrepidodera ferruginea (Scopoli, 1763), in North America (Coleoptera: Chrysomelidae: Galerucinae: Alticini)

The European rusted flea beetle Neocrepidodera ferruginea (Scopoli, 1763) is reported for the first time from Quebec and Ontario, Canada. It was likely introduced into southern Ontario at an international port on the Great Lakes in early 1970s, or possibly earlier in the 1960s. However, the exact location and date of introduction could not be precisely determined. The flea beetle has since dispersed northeastwards and reached Aylmer, north of Ottawa River, in Quebec, by 2003. This is about 375 km from Niagara Falls, where the oldest known specimens were collected in 1977. In 2009, various wild habitats and cultivated areas of Aylmer were surveyed. The host plants of the larvae could not be determined, but adults were swept from many plant species including various weeds and cultivated grasses: Alopecurus pratense (meadow foxtail), Dactylis glomerata (orchard-grass), Festuca rubra (red fescue-grass), and Poa pratensis (Kentucky blue-grass). Adults were also collected from flowers of several weeds: Aster sp. (undetermined species), Aster novae-angliae (New England aster), Ambrosia artemisiifolia (small ragweed), Echium vulgare (viper’s bugloss), Nasturtium officinale (water cress), Melilotus alba (white sweet-clover), Hypericum perforatum (common St. John’s-wort), Lythrum salicaria (purple loosestrife), Ranunculus acris (buttercup), and Solidago spp. (goldenrods). Since larvae are known to develop inside the roots and central stems of cereals, this new alien species represents a threat to Canadian agriculture, particularly if it reaches the Prairies in western Canada, where cereals represent a considerable part of their economy. European rusted flea beetle and Altise ferrugineuse europeenne are suggested for the English and French common names of this flea beetle, respectively.
