AbstractCucullia umbratica Linnaeus (Lepidoptera: Noctuidae), Agnippe prunifoliella Chambers (Lepidoptera: Gelechiidae), and Bryotropha plantariella Tengstrom (Lepidoptera: Gelechiidae), were significant bycatch in pheromone-based trapping systems for red-striped fireworm, Aroga trialbamaculella Chambers (Lepidoptera: Gelechiidae), in Nova Scotia, Canada. Cucullia umbratica is a European introduced species and a new macrolepidopteran recorded in continental Canada. The only previous record of this moth in North America was from the Magdalen Islands (Québec, Canada). Potential attractants for B. plantariella, A. prunifoliella, and C. umbratica are a result of this bycatch investigation.

Hebard (1915) and J. W. H. Rehn (1939 and 1939a) listed species of Orthoptera from Newfoundland but neither author reported any species of Gryllidae. Walker (1915) did not list any members of this family as inhabiting the Magdalen Islands.The first record of a cricket from Newfoundland was by Ander (1960) who recorded two immature females from Shoal Harbour, July 27, 1951. He somewhat doubtfully assigned these specimens to Nemobius fasciatus (DeGeer), stating: “I suppose that the specimens belong to the species Nemobius fasciatus (Degeer), widely distributed in North America, which is common in Nova Scotia (Piers 1918). The specimens agree very well with the description of fasciatus in Morse (1920) and Blatchley (1920), and as it is the only Nemobius known from Nova Scotia I have good reasons to suppose that the larvae belong to the species mentioned.”

The winter moth, Operophtera brumata (Linn.), was not known to occur in North America until 1949, when it was first reported from the south shore of Nova Scotia by Hawholdt and Cuming (2) and Smith (4). By that time this introduced species was well established. It is suspected that the winter moth in association with the fall cankerworm, Alsophila pometaria (Harr.), has been causing considerable defoliation of deciduous tree species in the region since the early 1930's (2). The habits and stages of the winter moth have been described briefly by Smith (S), who also has indicated the important differences between the winter moth and the fall cankerworm (4).

Lepidoptera Noctuidae

On 19 August 1982, a female noctuid moth resembling the Palearctic species Noctua pronuba (Linnaeus), which has recently been introduced into Eastern Canada (Neil 1981), was collected at an ultraviolet light at Simon Fraser University, Burnaby, British Columbia. An additional specimen, a male, was taken 13 September 1982. A third was seen, but not captured, 2 September 1982. A comparison of the British Columbia material with figures and descriptions of other Noctua species given by Bretherton et al. (1979) revealed them to represent Noctua comes (Hübner), based on their smaller size, light brown, narrow primaries, and well defined discal dot on the secondaries. This preliminary identification was later confirmed by external morphological and genitalic comparison with specimens of various Noctua species obtained from the Nova Scotia Museum collection in Halifax.

AbstractChaetocnema concinna (Marsham, 1802), a European flea beetle, is reported for the first time from Canada. Preliminary collection data indicate that it may feed on the same host plants as in Europe. It has been collected to date in Prince Edward Island, Nova Scotia, and Maine.

AbstractThe number of predators inhabiting nests of Hyphantria cunea Drury was recorded annually for 13 years in four areas in New Brunswick and two areas on the coast of Nova Scotia. The most common groups were the pentatomids and spiders, which sometimes reproduced within the nests, but the mean number per nest was low in relation to the number of H. cunea larvae in the colonies. The rate of predation on fifth-instar larvae was low. Small or timid predators appeared to prey largely on moribund larvae or small saprophagans during the principal defoliating instars of H. cunea.No relationship could be detected between the number of larvae reaching the fifth instar and the number of predators in the colony; nor could any functional or numerical response of the predators to either the initial number of larvae per colony or the population density of colonies be found. It is concluded that the influence of the nest-inhabiting predators is small and relatively stable, and may be treated as a constant in the development of models to explain the population dynamics of H. cunea.H. cunea is a pest in parts of Europe and Asia, where it has been accidentally introduced from North America. The introduction to other continents of the North American predator, Podisus maculiventiis (Say), is discussed briefly.

Abstract A description is provided for Isthmiella faullii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Apparently confined to Abies balsamea. DISEASE: Causes a needle blight of Abies balsamea. According to Darker (1932), it 'is the commonest and most destructive of the Hypodermataceae on Abies balsamea in eastern North America'. It is particularly damaging to seedlings and juvenile plants. In northern Ontario, from where the disease was originally identified, infection occurs during the summer, but signs of the disease do not appear until the following spring, when needles become brown and conidiomata develop, conidia being discharged in July, and shortly after this ascomata begin to form, maturing in July of the following year. GEOGRAPHICAL DISTRIBUTION: Reported from Canada: Nova Scotia, Ontario, Quebec and USA: Michigan and New Hampshire. TRANSMISSION: Through air dispersal of ascospores, which directly infect the leaves (Darker, 1932).

Tin Deposit

The East Kemptville tin deposit in Nova Scotia, the largest known tin deposit in North America, lies in a greisen zone within the Davis Lake Pluton, generally considered to be part of the Devonian South Mountain Batholith. Our dating of micas from within the deposit suggests that the greisenization process that accompanied mineralization took place about 295 ± 5 Ma ago, that is, ca. 60 Ma after the emplacement of the batholith.Hydrothermal alteration–mineralization activity in southern Nova Scotia coincided with extensive shearing and tectonism throughout the Hercynian orogen. The East Kemptville deposit appears to be approximately coeval with similar mineralization in southwest England, the Iberian peninsula, and northwest Africa and much younger than the Devonian Acadian orogeny.

Stratigraphic Succession

AbstractNew and archival collections from the Chelsey Drive Group of the Avalon terrane of Cape Breton Island, Nova Scotia, Canada, yield late Cambrian trilobites and agnostoid arthropods with full convexity that contrast with compacted, often deformed material from shale and slate typical of Avalonian Britain. Four species of the agnostoid Lotagnostus form a stratigraphic succession in the upper Furongian (Ctenopyge tumida–Parabolina lobata zones). Two species, L. ponepunctus (Matthew, 1901) and L. germanus (Matthew, 1901) are previously named; L. salteri and L. matthewi are new. Lotagnostus trisectus (Salter, 1864), the type species of the genus, is restricted to compacted material from its type area in Malvern, England. Lotagnostus americanus (Billings, 1860) has been proposed as a globally appropriate index for the base of ‘Stage 10’ of the Cambrian. All four species from Avalonian Canada are differentiated clearly from L. americanus in its type area in Laurentian North America (i.e., from debris flow blocks in Taconian Quebec). In our view, putative occurrences of L. americanus from other Cambrian continents record very different species. Lotagnostus americanus cannot be recognized worldwide, and other taxa should be sought to define the base of Stage 10, such as the conodont Eoconodontus notchhpeakensis.
