Since the publication of the writer's “Revision of the Aphelininæ of North America” (Bulletin 1, Technical Series, U. S. Department of Agriculture, Division of Entomology, 1895), the discovery of new forms, and especially of new genera, has been of very infrequent occurence. Species have been received from all parts of the world, owing to the extraordinary and world-wide development of interest in scale insects, which are the principal hosts of the Aphelininæ, yet nearly all of the forms thus received have been species already described, which have been carried with their hosts upon live plants to many different regions. It is, therefore, interesting to discover a new genus, even from a country like Chile, whose parasitic Hymenoptera are so little known. A most interesting feature of the discovery is that the new genus was reared from Aspidiotus hederœ (nerii) together with three of the cosmopolitan forms, namely, Aspidiotiphagus citrinus (Craw); Coccophagus immaculatus, How., and Prospalta aurantii, How. The writer is indebted to Mr. Edwyn C. Reed, of Rancagua, Chile, for this sending, as well as for many other favours.

Abstract Permian millipedes are rare, especially so considering the relative abundance of millipedes in Carboniferous rocks. We report an early Permian millipede fauna containing three new genera and species of millipedes (Oklahomasoma richardsspurense new genus new species, Karstiulus fortsillensis new genus new species, and Dolesea subtila new genus new species) found in fossil-producing pockets of the Fort Sill fissures exposed in the Dolese Quarry near Richards Spur, southwest Oklahoma, USA. These are the first new genera of invertebrates to be described from this site, one of the most prolific fossil-vertebrate sites in the world. We also comment on taxa with morphological similarities and note previously described occurrences of Permian millipedes as well as occurrences of fossil myriapods (millipedes and centipedes) in karst deposits (caves and fissure fills) in Europe, Africa, Asia, North America, and the Caribbean. In contrast with the forms found at Richards Spur, most of these previous accounts of millipedes found in caves and fissure fills are of Pleistocene forms that are closely allied to modern taxa. The taxa from Richards Spur bear some similarities to Pennsylvanian forms. Karst (cave and fissure) faunas should be ranked with concretion faunas, cannel coals, and amber faunas as a major source of fossil myriapods.

Preliminary Classification

During the course of preparing the Therevidae chapter for the soon-to-be published Manual of Nearctic Diptera (Canada Department of Agriculture 1981), we've found that the previously published descriptions of genera were totally inadequate to form a framework for the therevid species of North America. The genus Psilocephala Zett., for instance, was found to be polyphyletic, containing species from several diverse ancestors. An effort to describe the many new genera contained herein was begun because we realized the definitive nature of the forthcoming Manual of Nearctic Diptera and the importance of establishing a generic base for the Therevidae founded on synapomorphies. We have restrained ourselves from grouping the genera beyond the subfamilial level simply because we feel that better natural groupings can be formed once genera from other parts of the world are included in the scheme. We have attempted to place the described species in the new generic concepts at the end of each diagnosis. All North American genera are diagnosed, and male terminalia are figured for all genera. In total, 29 genera and 143 currently valid species have been described for North America, excluding Apsilocephala Krober (1914) and its included species, longistyla Krober (1914), which we feel does not belong within the family Therevidae. We have not included Melanothereva MaWoch (1932:249) that occurs in Chile, Peru, and parts of Argentina and contains a single Nearctic species, nigra (Bellardi) [1861:92, (Psilocephala)] that, to our knowledge, has not been rediscovered since it was first described from Mexico. The descriptions and keys follow morphological terminology developed by us. Male terminalia characters were originally defined and described by Lyneborg (1968a) and have since been modified slightly by Lyneborg (1972, 1976, and 1978) and by Irwin (1977a and 1977b). Female terminalia characters were defined and described by Irwin (1976) . Other morphological features are generally accepted in Diptera literature, and we refrain from detailing them here. The immature stages of Therevidae have not been used in developing this preliminary classification. Larval and pupal stadia are being gathered and associated with adults in the hope that eventually they will help to elucidate the proper phylogenetic placement of species within genera and genera within suprageneric taxa.

The World

AbstractThe well-known Carboniferous cyclothems of North America and Europe are discussed as examples to illustrate the great extent and lateral variation of sedimentary cycles. Very many other instances of cyclic sedimentation, in rocks of most ages, in many parts of the world, are also characterized by a more or less regular lateral migration of simultaneously existing depositional environments, caused by repeated transgressions and regressions of the sea over an epicontinental platform. Theories of varying complexity which have sought to explain cyclic sedimentation are briefly summarized, and it is suggested that the two basic requirements are a slowly subsiding sedimentary basin and more or less regular eustatic changes of sea level. The former will decide the geographical location. The latter could be a natural, periodic and world-wide consequence of the combination of the continuous effects of sedimentation and sostatic or orogenic movements of the sea floor.

New Bryozoans

Previous reports of Cambrian bryozoans have proved not to be bryozoans. No pre-Ordovician bryozoans have been recognized. The oldest unequivocal bryozoans known from North America, Britain, and Russia are evidently of early Arenigian age. New bryozoans recently collected from the Fenxiang Formation in the Daping and Guanzhuangping sections, situated in the area east of the Yangtze Gorges, are described here, including one new genus, Orbiramus, and six new species, Nekhorosheviella nodulifera, N. semisphaerica, Orbiramus normalis, O. ovalis, O. minus, and Prophyllodictya prisca. These are assigned to the Trepostomida, apart from the last species which belongs to the Cryptostomida. The new bryozoans are from the conodont Paltodus deltifer deltifer Zone of the late Tremadocian age, the first three species possibly being present in the P. deltifer pristinus Subzone at the base. Therefore, they are the oldest bryozoans known from anywhere in the world. Extensive reefs resulting from a major regression in the late Tremadocian were dominated by bryozoans in the upper Fenxiang Formation. The bryozoans lived in a shoal environment and accumulated essentially in situ, showing no signs of significant transportation.

A New Species

In the past, various authors have placed many species in genera that are now understood to be restricted to other regions of the world. Thus, in Africa, species of soft scale (Hemiptera: Sternorrhyncha: Coccomorpha: Coccidae) with this problem are those in Ceronema Maskell, a genus probably restricted to Australia; Ceroplastodes Cockerell, probably restricted to the New World; and Inglisia Maskell, which is restricted to New Zealand. The placement of these species is reviewed here. Four of the known Ceronema species are placed in three new monotypic genera, Neoceronema gen. nov., Illovococcus gen. nov. and Bugandacoccus gen. nov., as Neoceronema africanum (Macfie) comb. nov., N. brachystegiae (Hall) comb. nov., Illovococcus mobilis (Brain) comb. nov. and Bugandacoccus gowdeyi (Newstead) comb. nov.; Ceroplastodes ritchiei Laing and C. zavatarii Bellio are transferred to Drepanococcus Williams & Watson, as D. ritchiei (Laing) comb. nov. and D. zavattarii (Bellio), comb. nov., and Inglisia grevilliae Hall, I. pluvialis Hodgson and I. theobromae Newstead are transferred to Cryptinglisia Cockerell as C. grevilliae (Hall) comb. nov., C. pluvialis (Hodgson) comb. nov. and C. theobromae (Newstead) comb. nov. Keys are provided to all Drepanococcus and Cryptinglisia species, and all the African species discussed are illustrated. In addition, another new genus of African Coccidae is described, Testudovestis gen. nov., to take a new species somewhat similar to Eucalymnatus Cockerell: T. africana spec. nov. In addition, a new species of Coccus L.: Coccus moorei, spec. nov., and a new species of mealybug (Heliococcus tinglei spec. nov., Pseudococcidae), are described, both from mainland Africa. The lecanodiaspid Lecanodiaspis zygophylli Hodgson is also recorded from Nigeria for the first time.

1. These studies were originally intended to form the basis of a world monograph of the Siricidae ; such a work cannot be completed under present circumstances.2. Two ratios are introduced as useful characters for separating species : the ovipositor/forewing ratio and the sawsheath/ovipositor ratio. These ratios were obtained from all specimens of all the species represented in the British Museum collections and the results are tabulated. They were found not to vary with the size of the insects.The former ratio is specially useful in the genus Urocerus, which has a long ovipositor, and the latter ratio in the genus Sirex, which has a shorter ovipositor.3. Keys are given to the genera of the world. Of Semenov's new genera, Xoanon is accepted but not Xanthosirex. A new genus Eriotremex is erected for certain Indo-Malayan species previously included in Tremex.4. Keys are given to the European species, which are compared critically with related species from other parts of the world. A key to the species of Eriotremex, gen. nov., is also given.5. Sirex noctilio, F., and S. juvencus, L., are recorded for the first time from North America and S. cyaneus, F., from the continent of Europe. The common Urocerus of the northern Palaearctic region is shown to be more closely related to the Nearctic U. gigas flavicornis, F., than to the central European U. gigas gigas, L., and is treated as a new subspecies—U. gigas taiganus, subsp. nov. U. gigas tibetanus, subsp. nov., is described from the Himalayas. U. sah, Mocsáry, is treated as a subspecies of U. augur, Klug, and U. cedrorum, Smith, as a synonym of U. augur augur, Klug.6. The British Siricidae are discussed, and it is suggested that U. gigas taiganus, subsp. nov., and the form of S. juvencus, L., with entirely black antennae may be native in the Caledonian forest.7. It is argued that modern Siricidae could not have been derived from the Jurassic Pseudosiricidae.8. The known Oriental and Himalayan Siricidae are listed and discussed. Urocerus multifasciatus, Takeuchi, and Eriotremex formosanus, Matsumura, are mentioned as two species originally described from Formosa but shown also to occur on the mainland. Urocerus niger, sp. nov., is described from the Himalayan region, and the name Eriotremex malayanus, sp. nov., is given to a form described without a name by Forsius from Malaya.9. Several errors in previous work on Siricidae are corrected.

Four new venerid species from the Cretaceous of the North American Pacific Slope are described and four previously described species are reassigned. Of the new species, two are allotted to new genera: Rhaiphiale based upon Rhaiphiale pharota n. sp. and Egrona based upon Egrona fallax n. sp., both Turonian in age and from southern California. The other new species are Loxo quintense n. sp., of late Maastrichtian age from California, and Paraesa cedrina n. sp., late Albian in age from Baja California, Mexico. The previously described species “Meretrix” arata Gabb, 1864, Turonian, and “?Meretrix” fragilis Gabb, 1869, late Maastrichtian, are placed in the new genus Callistalox; “Meretrix” lens (Gabb, 1864), Campanian age, and Flaventia zeta Popenoe, 1937, Turonian, are provisionally assigned to Paraesa Casey, 1952. This is the first identification of Paraesa from the Pacific Slope of North America. No species of Flaventia Jukes-Brown, 1908, is now known in Pacific Slope faunas.

Academic Philosophy

Since the late 1970s there has been within the world-wide environmental movement increasing dissatisfaction with moderate or reform environmentalism, and more radical tactics have been advocated and used to respond to the human destruction of nature. These range from typical kinds of political protest, such as rallies and marches, to environmental civil disobedience and the more militant environmental actions known as ‘monkey-wrenching’, ‘ecotage’, or ‘ecosabotage’. The use of these ‘ecotactics’ has led inevitably to controversy in the environmental movement itself and in public discussions of environmentalism in North America and elsewhere. The same cannot be said, however, about academic philosophy, where it is rare to find assessments of these actions or of their connections to the wealth of philosophical ideas in environmental ethics and ecophilosophy. At the same time there are many traditional philosophical theories that have implications for these kinds of behaviour even though the theories were constructed originally without examples of ecotactics in mind. In particular, theories about the nature and justifications of civil disobedience provide yardsticks by which some forms of environmental disobedience can be assessed, and I will turn to two widely known philosophical accounts, those of John Rawls and Carl Cohen, to consider how well they accomplish this task.

In 1937-38 the Argentine Department of Agriculture initiated an exchange of grasshopper parasite material with the Canadian Department of Agriculture which was engaged in a study of the natural control of grasshoppers in various provinces of Canada. By 1942 it was considered desirable to introduce exotic species of parasites into Canada on as wide a scale as possible, and the temperate regions of South America were selected as being the most promising for a survey. The parts of the temperate zone of South America to which preferential attention was to be given included the countries of Uruguay, Argentina, and Chile. The well known grasslands of the Rio de la Plata area have been partially transformed into one of the world centres for cereal production and as in other parts of the world increased grasshopper populations constitute a major problem in the agriculture of the region. Here species of the genus Dichroplus are frequently pests in the way in which members of the closely related Melanoplus are in North America.
