The present paper brings together the latest knowledge on the species of Mecormmu known to occur in the Nearctic region. Study of the genitalia, external structures, and distribution, show that species vary considerably in structure and colour, and these variations have contributed in the past to the confusion in naming the species of Mecomma. Lack of specimens in collections has also hindered the study of this group and it is only within the last few years that large collections made in Canada and the United States have helped to solve somc of the problems.

Based on the geographic distribution database of the Orthoptera Species File, the diversity and distribution of the superfamily Grylloidea in the Nearctic region was studied using the statistics and Sorensen dissimilarity coefficient. A total of 164 species or subspecies belonging to 4 families, 9 subfamilies and 27 genera were recorded from this region; among which Gryllidae (93, 56.70%), followed by Trigonidiidae (44, 26.83%), Mogoplistidae (25, 15.24%), and Phalangopsidae (2, 1.22%). The diversity exhibits an asymmetric distribution pattern, with the southeastern coastal plain, the Interior Plateau and Piedmont of the United States was the most abundant. At the same time, the regional similarity of species distribution was analyzed, and the Nearctic was divided into four subregions: Boreal & Arctic zone of North America, Eastern temperate North America, Northeast temperate North America, and Southern North America & western temperate North America.

The first record of the occurrence in North America of the white-tipped clover case-moth, Coleophora frischella L., was made in June 1966 when a single adult was taken by Heinemann on Picton Island, N.Y., in the St. Lawrence River (Freeman, personal communication). Independently, Trieselmann collected the larvae from white sweet-clover, Melilotus alba Desr., on 28 July through to 8 August 1966 at many points around Pembroke, Ont. Detailed examinations made at two of the collection points indicated that between 15 and 20% of sweetclover seeds were damaged. Because of its potential economic significance, the authors wish to make the presence of this species known to agricultural entomologists in Canada and the United States.

Economic activity accelerated sharply in the United States at the beginning of this year. GDP rose by 1¼ per cent in the first quarter, to a level 3.8 per cent higher than a year earlier. This was the fastest quarterly growth for two years. The acceleration in growth was unexpected given that the present cyclical expansion has now lasted for over seven years. Private sector demand is still continuing to be supported by the sustained appreciation in equity prices over the past three years, and the appreciation of the dollar has helped to hold down the inflationary pressures that are being built up as the labour market begins to tighten. The unemployment rate fell to 4.3 per cent in April, the lowest rate since 1970.

The focus of this article is to track the progress that has been made on behalf of<br />animals within the legal institutions of the United States. While there is an obvious focus on<br />the adoption of new laws, there are many steps or changes that are necessary within broader<br />legal intuitions if substantial progress is to be made in the changing and enforcing of the<br />laws. For example, at the same time that legislatures must be convinced of the need for<br />change, so must the judges believe in the new laws, otherwise enforcement of the law will be<br />not forthcoming.<br />Besides the court and the legislature, legal institutions include law schools, legal publications,<br />and the various associations of lawyers and law professors. What is the visibility and<br />credibility of animal issues within these institutions? Without progress within all aspects of<br />the legal community, success on behalf of animals is not possible. We in the United States<br />have made progress, particularly in the past ten years, but we have much yet that needs to be<br />done. By charting the progress and lack of progress in the United States, the readers in<br />Brazil and other countries will have some landmarks by which to judge the progress of the<br />issue of animal rights/welfare within their own country.

The fossil record of dinosaurs from the Early Cretaceous of eastern North America is scant, and only a few sediments to the east of the continent are fossiliferous. Among them is the Arundel Formation of the east coast of the United States, which has produced among the best dinosaur faunas known from the Early Cretaceous of eastern North America. The diverse dinosaur fauna of this formation has been thoroughly discussed previously, but few of the dinosaur species originally described from the Arundel are still regarded as valid genera. Much of the Arundel material is in need of review and redescription. Among the fossils of dinosaurs from this formation are those referred to ornithomimosaurs. Here, I redescribe ornithomimosaur remains from the Arundel Formation which may warrant the naming of a new taxon of dinosaur. These remains provide key information on the theropods of the Early Cretaceous of Eastern North America. The description of the Arundel material herein along with recent discoveries of basal ornithomimosaurs in the past 15 years has allowed for comparisons with the coelurosaur Nedcolbertia justinhofmanni, suggesting the latter animal was a basal ornithomimosaurian dinosaur rather than a “generalized” coelurosaur. Comparisons between the Arundel ornithomimosaur and similar southeast Asian ornithomimosaurian material as well as ornithomimosaur remains from western North America suggest that a lineage of ornithomimosaurs with a metatarsal condition intermediate between that of basal and derived ornithomimosaurs was present through southeast Asia into North America, in turn suggesting that such animals coexisted with genera having a more primitive metatarsal morphology as seen in N. justinhofmanni.

In The Teaching Gap (1999), James W. Stigler and James Hiebert describe differences between mathematics instruction in Japan and the United States. They attribute some of these differences to a commonly used method of professional development in Japan called lesson study: “The lesson-study process has an unrelenting focus on student learning. All efforts to improve lessons are evaluated with respect to clearly specified learning goals, and revisions are always justified with respect to student thinking and learning” (p. 121). Over the past decade, many groups of educators in North America have implemented various forms of lesson study.

Abstract This paper has presented a report on the progress which has been made in the cellular rubber field during the past several years; now a few words about the future. It is said that Russia has seventeen kinds of Buna-S. At present the United States has only one kind, namely, GR-S. Of course, this country does have several types of Buna-N and several types of Neoprene. Possibly the day will come when there will be available one or more types of both solid and liquid synthetic rubbers made specifically for the manufacture of cellular rubber products. In the past, many production difficulties in this field have been due to variation in the plasticity and in the rate of cure of different lots of natural rubbers, and to variation in the stability and rate of cure of different shipments of natural rubber latices. These difficulties may well be overcome in the synthetic rubbers of tomorrow.
