The Genus Phragmatobia in North America, with the Description of a New Species (Lepidoptera: Arctiidae)
Excerpt: This paper, based on the examination of 1,879 specimens, serves to resolve the taxonomic problems involving the three North American species of Phragmatobia. The genus Phragmatobia, the ruby tiger moths, has had a checkered history since it was described by Stephens in 1829 (type, by monotypy, Noctua j\u27uliginosa Linnaeus, 1758). Although many species have been described in or transferred to this genus, in both the Old and New Worlds, most of them have been removed to other genera. By 1902 Dyar recognized only two North American species, a status since then unchanged (McDunnough, 1938; Forbes, 1960). Despite the recent stability of the names, there has been much confusion as to which names to apply to particular specimens. This problem is resolved below, with the description of a third North American species, long confused with the two named species
Nature in Don Segundo Sombra and the Virginian
Environment and culture shape human beings, both as individuals and as societies. In all the vast plains of the Americas where a cattle industry developed, a human type evolved a distinct way of life: the gaucho in Argentina, the charro in Mexico, the llanero in Venezuela, the guaso in Chile, and the cowboy in the United States and Canada. 1 Domingo Faustino Sarmiento, an Argentine intellectual who was an avid reader of James Fenimore Cooper, was perhaps the first to state clearly in regard to the Americas that wherever a similar combination of geographical features occurs, parallel customs and occupations have evolved among otherwise unrelated peoples, but the observation has since become almost a commonplace.2 Naturally, people with parallel customs have produced similar bodies of literature, but the mythic underpinnings of that literature are not necessarily the same, as a comparison of two outstanding novels shows
Review of Cowboys of the Americas
Some twenty years ago, while preparing a course on the frontier in literature, I first began to research the horsemen of the Americas. At that time, there were available only the numerous classic studies of the American cowboy, those by Dobie, Hough, Folsom, Abbott, Adams, Branch, Frantz and Choate, Santee, to name a few, but on the charro (vaquero), the llanero, the gaucho, or the huaso (guaso), very little was to be found. The few books, articles, extracts from travel logs that existed offered casual observations of these horsemen rather than a focused, coherent study. Only Edward Larocque Tinker\u27s seminal work, The Horsemen of the Americas and the Literature They Inspired, offered a scholarly incursion into the field

A Numerical Study of Non-Perturbative Unification
Non-perturbative unification provides an attractive framework for exploring physics beyond the Standard Model. It assumes nothing about the form of the unified physics, yet provides low-energy predictions of Standard Model couplings. In this investigation, we consider models that add multiplets of SU(5) to the Standard Model in order to unify in this way. We present a search for those that correctly reproduce experimental results and find that some models unify with added matter at the scale of the potential future 100 TeV collider. We conclude with an illustrative example of how these models can be built off of for further model building beyond the Standard Model with extractable phenomenological results
