Aeschna verticalis Hagen has been for some years the only species of the genus from eastern North America, whose nymph was unknown, except the rare A. mutata Hagen. At last, unexpectedly, the writer found A. verticalis in transformation at Clementsport, Annapolis Co., Nova Scotia.

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).

Agglutinated Foraminifera

The sea cliffs at Joggins, Nova Scotia, are the most extensive and continuous Carboniferous section in eastern North America. Although the section has been considered to have formed within a nonmarine depositional basin, paleobiological information indicates that parts of the section were deposited in brackish water. The occurrence of a trace-fossil assemblage, which includes Cochlichnus, Kouphichnium, and Treptichnus, is part of an assemblage of biogenic structures that apparently reflects paleodeposition within fluvial systems that may have experienced distal marine influences. Presence of agglutinated foraminifera characteristic of brackish-water environments supports this interpretation. This information provides new evidence of brackish-water conditions at Joggins such as those now being widely recognized in other Carboniferous coal-bearing sections.

A New Species

A new species of Isoetes, Isoetes acadiensis, from North America is described. The particular combination of characters of microspore and megaspore ornamentation, spore sizes, and chromosome number separates this species well from all existing species. Its range is restricted to the northeastern seaboard of North America and it occurs most commonly in Nova Scotia.

Cavity Nesting

AbstractThe identity, richness, and abundance of true flies (Diptera) from the nests of three cavity-nesting raptors (Aves) were investigated in northern Nova Scotia, Canada. After fledging, flies were extracted from the nest material using Berlese funnels within an emergence chamber. Thirty-one species/morphospecies from 14 families were collected, including eight new records for Nova Scotia and two new records for eastern North America.

A biosystematic study of the genus Atriplex, based on field, herbarium, culture, and cytological work delineates the taxa of this genus occurring in Nova Scotia. The study gives detailed morphological descriptions of eight species, and reports their chromosome numbers, breeding systems, ecology, and distribution. Atriplex patula L., A. hastata L., A. littoralis L., and A. glabriuscula Edmondston, considered as varieties of A. patula by recent North American authors, are given specific rank. The name Atriplex hastata L. is found to be misapplied. The correct name for this taxon is Atriplex triangularis Willdenow. Two new species—Atriplex acadiensis, a tetraploid, and A. Franktonii, a diploid—are described. A hexaploid species, A. subspicata (Nutt.) Rydb., not previously recognized from eastern North America, is reported. M. L. Fernald's report of A. patula var. bracteata Westerlund from Nova Scotia is shown to be based on an incorrect determination. Atriplex glabriuscula var. oblanceolata Vict. & Rousseau, and A. patula var. bracteata Westerlund are relegated to synonymy.

AbstractThe winter moth, Operophtera brumata (L.), a recent introduction to North America, is a serious pest of apple in Nova Scotia. Natural controls, mainly the parasite Cyzenis albicans (Fall.), reduce its rate of increase, and selective chemical controls are applied to maintain economic levels. Its maximum density is limited by its food supply in neglected orchards. The mean freezing point of O. brumata winter eggs is −31°F. Egg mortality increases appreciably with increase of duration of exposure to low temperatures in the −26°F to −34°F vulnerable range. It seems probable that winter moth will continue to spread slowly over much of Eastern North America.

Wide Geographic Distribution

A fragment of a right dentary with one postcanine tooth from the Upper Triassic (Rhaetian) Scots Bay Member of the McCoy Brook Formation at Wasson Bluff, Nova Scotia, Canada, represents the first record of the tritylodontid cynodont Oligokyphus from the early Mesozoic of eastern North America. In addition, three dissociated postcranial bones from the same horizon and locality are referable to derived cynodont therapsids. One of these elements, a nearly complete right humerus, can be assigned to Tritylodontidae. Two other bones, an ulna and incomplete ischium, belong to indeterminate derived cynodonts but show no features allowing more precise taxonomic identification. The presence of Oligokyphus in the McCoy Brook Formation provides additional evidence for the remarkably wide geographic distribution of many latest Triassic and Early Jurassic continental tetrapods.

Extensive List

With his usual kindness Mr. C. A. Frost sent me the subjoined Heteroptera collected by him in Nova Scotia in July 1927 and 1929, at Portaupique and Westchester. The latest data available on bugs from this part are contained in Blatchley's Heteroptera of Eastern North America; the most extensive list thus far pubished is Parshley's 1923 paper, Records of Nova Scotian Heteroptera, which appeared in Proceedings of the Acadian Entomological Society for 1922, pp. 102, 108. The present records have been checked against these; the order of the species, for convenience, is that of Blatchley's Heteroptera.
