Large stands of Euphorbia cyparissias L. in Ontario supporting aecia of Uromyces striatus Schroet. presented an opportunity for the author to study this stage of the rust hitherto little known in North America since its discovery here in 1947. The mycelium was found to be systemic and perennial and the aeciospores capable of infecting many species of Medicago and some yellow-flowered species of Trifolium. Pisum sativum was just slightly susceptible. Both diploid and tetraploid nuclear conditions of E. cyparissias have been found rusted and E. esula, long suspected as a host in Europe, has also been found rusted and the connection to Leguminosae shown by inoculation. Specimens resulting from inoculations (109) and from field collections from Canada (33), United States (18), and Europe (13) were identical in spore morphology. This, plus susceptibility of Leguminosae from Europe to the inoculum from Ontario, supports the suggestion that the rust was introduced to North America from Europe. It is further suggested that U. striatus was introduced on either or both alternate hosts independently. The common occurrence of telia is recorded and the fungus is redescribed.

This chapter describes two invasive crane fly species which are pests of turfgrass, particularly in the northwestern and northeastern United States, as well as southern British Columbia and the metropolitan Toronto area in Canada. The European crane fly and the common or marsh crane fly, order Diptera, family Tipulidae, subfamily Tipulinae, have elongated maxillary palpi that distinguish members of this subfamily from other subfamilies. Larvae of invasive crane flies are sometimes called leatherjackets, in part because the pupae are leathery in appearance. Invasive crane flies have a relatively limited distribution in North America, but can cause considerable damage on golf courses, lawns, athletic fields, and sod farms, as well as forage fields and hayfields. The chapter also looks at the frit fly, which belongs to the family Chloropidae.

Examination of material of the genus Campichoeta Macq. (= Thryptocheta Rond.) from both the Old and the New Worlds, follawing clarification of the identities of most of the Palaearctic species by Basden and Collin (1958), revealed significant new information on the taxonomy of the genus. It showed that the common species in North America, heretofore called Thryptocheta micans Hendel (1911), is the same as Campichoeta griseola (Zett.) (1855) known from a single collection apparently made by Boheman in central Sweden about 1852. Also, it showed that an undescribed species occurs in southwestern United States.

The consolidation of neo-liberalism since the 1980s has presented several challenges to unions in North America. Through the restructuring of the state and the promotion of globalization, neo-liberalism has made the terrain of struggle more daunting for unions. Changes in the organization of work are also implicated in the common threats to organized labour and workers more generally. These common pressures on labour in Canada, the United States and Mexico, however, have resulted in different outcomes for the three movements. Many have suggested that these common pressures should be met with an increased emphasis on transnational labour cooperation. It is argued here it is possible to build international solidarity without first building union capacities at the level of the local plant and at the level of the nation state.

Acroptilon repens (L.) DC. (Russian knapweed) is a long-lived perennial weed from central Asia that is widely distributed in the western United States (U.S.). Recently, accessions of a rust disease were collected from Colorado (CO), Montana (MT), and Wyoming (WY) for comparison with Eurasian isolates. U.S. accessions had two-celled teliospores with slight constrictions in the middle and urediniospores with three germ pores ± equatorial in location. Urediniospores were (state, width × length, [n = 100]): CO, 16.4 to 25.7 × 19.2 to 27.0 μm; MT, 18.4 to 23.1 × 17.4 to 24.6 μm; and WY, 18.0 to 26.2 × 20.2 to 26.7 μm. These were similar to those of 16.6 to 25.7 × 21.2 to 28.0 μm from two New Mexican (NM) herbarium specimens (BPI Nos. 1107952 and 1110177) (1). Teliospores measured 19.9 to 27.7 × 29.8 to 47.4 μm, 17.4 to 26.0 × 32.4 to 44.2 μm, 16.5 to 27.5 × 29.4 to 45.7 μm, and 18.7 to 27.6 × 31.0 to 46.4 μm for CO, MT, WY, and NM accessions, respectively. These rust isolates have been identified as Puccinia acroptili Syd. on the basis of host plant record and spore morphology (2). To our knowledge, this is the first record of P. acroptili in CO, MT, and WY. Besides NM, P. acroptili has been reported in North America from California, British Columbia, and Saskatchewan.

Several authors (Berry, 1916, 1931; Brooks, 1955; Cockerell, 1908, 1910) have reported evidence of damage by leaf-cutter bees (Hymenoptera: Megachilidae) from the Tertiary of the United States. These have been predominantly Eocene in age. During field investigations (1990-1991), four further fossil plant specimens with possible leaf-cutter bee damage were discovered from the middle Eocene sediments of the Klondike Mountain Formation near Republic (Ferry County), Washington (Figure 1), and are reported here to draw attention to the common occurrence of these kinds of insect “trace fossils” in the paleobotanical record.

Fish Louse

A curious error affects the names of three North American clupeids—the Alewife, American Shad, and Menhaden. The Alewife was first described by the British-born American architect, Benjamin Henry Latrobe in 1799, just two years after what is generally acknowledged as the earliest description of any ichthyological species published in the United States. Latrobe also described the ‘fish louse’, the common isopod parasite of the Alewife, with the new name, Oniscus praegustator. Expressing an enthusiasm for American independence typical of his generation, Latrobe humorously proposed the name Clupea tyrannus for the Alewife because the fish, like all tyrants, had parasites or hangers-on.

This essay introduces a special issue of Nova Religio on magic and politics in the United States in the aftermath of the 2016 presidential election. The articles in this issue address a gap in the literature examining intersections of religion, magic, and politics in contemporary North America. They approach political magic as an essentially religious phenomenon, in that it deals with the spirit world and attempts to motivate human behavior through the use of symbols. Covering a range of practices from the far right to the far left, the articles argue against prevailing scholarly treatments of the use of esoteric technologies as a predominantly right-wing phenomenon, showing how they have also been operationalized by the left in recent history. They showcase the creativity of magic as a form of human cultural expression, and demonstrate how magic coexists with rationality in contemporary western settings.

The reception of common law in the United States was stimulated by a very popular and influential treatise Commentaries on the Laws of England by Sir William Blackstone, published in the late 18th century. The work of Blackstone strengthened the continued reception of the common law from the American colonies into the constituent states. Because of the large measure of sovereignty of the states, common law had not exactly developed in the same way in every state. Despite the fact that a single common law was originally exported from England to America, a great variety of factors had led to the development of different common law rules in different states. Albert W. Alschuler from University of Chicago Law School is one of the contemporary American professors of law. The part of his works can be assumed as academic historical-legal narrations, especially those concerning Blackstone: Rediscovering Blackstone and Sir William Blackstone and the Shaping of American Law. Alschuler argues that Blackstone’s Commentaries inspired the evolution of American and British law. He introduces not only the profile of William Blackstone, but also examines to which extent the concepts of Blackstone have become the basis for the development of the American legal thought.
