In a recent contribution in this Journal, I described a few new Diptera from Canada. The present paper contains descriptions of six new Canadian species and two from the United States, the types of the Canadian species being in the Canadian National Collection. The descriptions of two of the species of Ptiolina in this paper have been prepared by Dr. M. D. Leonard and are included in order that the key to species may be complete. From our study of this genus it seems probable that there are other species to be found, especially in the north where so little collecting has been done.

This forum builds on the discussion stimulated during an online salon in which the authors participated on June 25, 2020, entitled “Archaeology in the Time of Black Lives Matter,” and which was cosponsored by the Society of Black Archaeologists (SBA), the North American Theoretical Archaeology Group (TAG), and the Columbia Center for Archaeology. The online salon reflected on the social unrest that gripped the United States in the spring of 2020, gauged the history and conditions leading up to it, and considered its rippling throughout the disciplines of archaeology and heritage preservation. Within the forum, the authors go beyond reporting the generative conversation that took place in June by presenting a road map for an antiracist archaeology in which antiblackness is dismantled.

As noted below the two North American species described in Syndipnus by workers appear to belong in other genrra. In Europe the gunus is represented by nearly a score of species and has been reviewed in recent years by two writers (1, 2). North American collections contain very few representatives of the genus; after combining the material in the National Collection with that from the United States National Museum, the latter kindly loaned to me by Mr. R. A. Cushman, only thirty-seven specimens are available for study.

The research is devoted to the study of the origin of the historiography of the topic of the genesis of the US foreign policy. The key thesis of the work challenges the established position in the scientific literature about the fundamental role of the work of T. Lyman, Jr. «The diplomacy of the United States: being an account of the foreign relations of the country, from the first treaty with France, in 1778, to the Treaty of Ghent in 1814, with Great Britain», published in 1826. The article puts forward an alternative hypothesis: the emergence of the historiography of the genesis of the foreign policy of the United States occurred before the beginning of the second quarter of the XIX century – during the colonial period and the first fifty years of the North American state. A study of the works of thirty-five authors who worked during the 1610s and 1820s showed that amater historians expressed a common opinion about North America’s belonging to the Eurocentric system of international relations; they were sure that both the colonists and the founding fathers perceived international processes on the basis of raison d’être. The conceptualization of the intellectual heritage of non-professional historians allowed us to distinguish three interpretations of the origin of the United States foreign policy: «Autochthonous» – focused on purely North American reasons; «Atlantic» – postulated the borrowing of European practice of international relations by means of the system of relations that developed in the Atlantic in the XVII–XVIII centuries; «Imperial» – stated the adaptation of the British experience. The obtained data refute the provisions of scientific thought of the XX–XXI centuries and create new guidelines for further study of the topic.

How did the U.S.-Colombia free trade agreement come about? The officially named “U.S.-Colombia Trade Promotion Agreement” was the stepchild of a rancorous hemispheric divorce between the United States and five Latin American governments over the proposal to extend the North American Free Trade Agreement...
