Description: Anticipating a revision of the genera and subgenera of the tribe Anthophorini, a number of south-east Asiatic species previously included in Anthophora Latreille, are transferred by the author to Amegilla Friese. The types were studied of Anthophora villosula F. Smith, and of 19 valid and 3 invalid species of Amegilla (i.e., of all species discussed, except that of himalajensis Radoszkowski), and a key to their identification is included. The following new species are described: A. proboscidea, \xe2\x99\x80 (Simalur I.), sumatrana, \xe2\x99\x82\xe2\x99\x80 (Sumatra), pagdeni, \xe2\x99\x82 \xe2\x99\x80 (Malaya), and leptocoma, \xe2\x99\x82 \xe2\x99\x80 (Siam & Malaya). Re-descriptions of both sexes and figures are given of A. insularis (F. Smith), himalajensis (Radoszkowski), florea (F. Smith), and urens (Cockerell). Apart from the specific descriptions, notes and records are provided concerning geographical distribution, new localities, and the identity of plants visited. The following cases of synonymy are established : A. fulvohirta Meade-Waldo, 1914 (= insularis F. Smith, 1858) A. proserpina Gribodo, 1893 (= himalajensis Radoszkowski, 1882) A. pahangensis Meade-Waldo, 1914 (= himalajensis Radoszkowski, 1882) A. pahangensis Cockerell, 1927 (= pendleburyi Cockerell, 1929) A. anthreptes Lieftinck, 1944 (= pendleburyi Cockerell, 1929) Anthophora villosula auct, nec F. Smith, 1854 (= Amegilla spec. diff.) Anthophora soror J. P\xc3\xa9rez, 1905 (= Anthophora villosula F. Smith, 1854) Anthophora pingshiangensis Strand, 1913 (= Anthophora villosula F. Smith, 1854)

Description: The present paper is the result of an examination of some type specimens in the Brussels Museum, collected by G. Semper in the Philippines and described by Friedrich Brauer in 1868; it includes also a discussion of one species recorded from these islands by Edm. de S\xc3\xa9lys Longchamps in the last part of his "Synopsis des Agrionines", in 1877. These were rendered accessible to study during my visit to Brussels in June, 1938, by Mons.\nAntoine Ball, at that time entomologist of the Mus\xc3\xa9e Royal d\'Histoire Naturelle. Through his kindness I was permitted afterwards to borrow the types for further study and to keep them for almost twenty years. This enabled me to make comparisons with certain species included in a splendid collection of Philippine dragonflies in the Senckenberg Museum, sent to me on loan in 1938 ; these had been assembled by G. Boettcher, many years in advance, in behalf of the late Dr. F. Ris, whose collection was bequeathed to the Natur-Museum Senckenberg, Frankfurt a. M.\nOf the six species of Amphicnemis and Teinobasis described by Brauer and de S\xc3\xa9lys, only three were represented in the Boettcher collection, the rest belonging either to undescribed forms, or might prove identical with some species or other recorded by J. G. Needham & M. K. Gyger, in their account (1939) of the Zygoptera of the Philippines.\nJudging by the great number of apparently undescribed species at present available for study, each of the Philippine islands has developed an astonishingly rich and diversified zygopterid fauna. Among the species pertaining to such genera like Drepanosticta, Risiocnemis, Amphicnemis and Teinobasis, several were found to approach each other so closely that detailed descriptions and accurate camera lucida drawings of morphological features are

Description: The writer ascertains the existence of a fairly large number of Old World Gomphidae exhibiting a mixture of admittedly epigomphine and gomphine characters; he emphasizes the point that certain features hitherto considered of primary importance can no longer be used as a basis for subfamily grouping. Examples are given of intermediate genera whose proper allocation cannot even be estimated, for which reason the segregation of the Epigomphinae is considered ill-founded and must be suspended.

Through the kindness of the authorities of the British Museum (Natural History), the Institut Royal des Sciences Naturelles de Belgique at Brussels, and the Museum of Zoology, Ann Arbor, I have recently been permitted to compare

Description: Up to the present, three species of the Libellulid genus Lanthanusa Ris have been described, all from the mountain regions of New Guinea. One of these, the genotype L. cyclopica Ris, is a female in the Leiden Museum collected more than half a century ago somewhere in the Cycloop Mountains (North New Guinea) ; the male has remained unknown and the species has never been found again. Two others, richardi Lieft, and lamberti Lieft., were subsequently discovered in the mountain forests of central New Guinea and are known from both sexes. All three species have been discussed at length in the writer\'s account of the Anisoptera of the Third Archbold Expedition (Treubia, 1942, 18 : 493-499, figs. 40-45).\nIn this short paper the descriptions are offered of two more species, one from the high mountains of northeast New Guinea, and one from the island Goodenough. It is interesting to see that all members of Lanthanusa are apparently restricted to high elevations and do not occur below a height of about 1350 metres above sea-level, L. lamberti from the moss-forests near Lake Habbema (2800-2850 m) being the highest recorded Libellulid from New Guinea.\nOwing to their cryptic colouring the adults are probably easily overlooked insects as they rest on leaves in sunlit openings of the forest. The larva is still unknown but, like Huonia, the insects probably breed in forest-marshes or small streams.\nLanthanusa sufficiens, sp. n.

Description: The genus Podolestes, as far as at present known, is confined to the Malaysian subregion of the Indo-Australian Archipelago. Descriptions and drawings of structural details of four species are to be found in two of the writer\'s previous papers on Malaysian dragonf lies, viz.: New and little known Odonata of the Oriental and Australian Regions.\nTreubia, 15, 1935: 177-183, fig. 1-3.\nDescriptions and records of South-East Asiatic Odonata (II). Ibid. 17, 1940: 347-350, fig. 4-5.\nThe species of Podolestes have been found in marshes and along muddy creeks flowing through wooded areas in low country. Owing to their retiring habits the insects are but seldom encountered and all species are rare in collections. Little or nothing is known of their life-histories, and the larva is still unknown.\nThe six known members of the genus, two of which are here described for the first time, may be distinguished by the following Key to the species. 1. Dorsum of thorax uniform metallic bronzy black. Labrum, mandibles and genae shiny black. Ante-alar triangles bronzy-black, unmarked. Nervure Ac situated much nearer Ax2 than Ax1; nervure Ab complete, meeting Ac at the wing-margin. Quadrilateral short, markedly widened distally, costal and distal sides approximately equal in length in fore wing. Three to four postquadrangular antenodal cells. Male anal appendages of slender build, blackish in colour; superior pair a trifle longer than the inferiors; apex of inf. app. expanded, truncated and slightly notched 2. \xe2\x80\x94. Dorsum of thorax with two pairs of light-coloured spots on mesepisternum, and sides with an oblique band extending from below the spiracle upwards as far as the dorsal

Description: The present memoir contains some notes and observations on the taxonomy and biology of the beetle genus Mormolyce Hagenbach. Though only too well known among coleopterists ever since their discovery, these remarkable carabids do not appear to have been critically studied in recent years. As a matter of fact, very little information on them has been supplied during the last fifty years or so, nearly all observations of more than passing interest being contained in what may be aptly called \xe2\x80\x9cclassical\xe2\x80\x9d memoirs, written by some earlier students whose works are listed in the literature cited at the end of this paper. The present authors, therefore, have gratefully accepted this opportunity to put on record the results of a fresh study of these insects by reviewing the facts already known in a joint attempt to check previous investigations against their own. The junior author has revised the systematics, taxonomy and early stages of Mormolyce, his studies being based on a rich supply of material including specimens and illustrations of great historical interest. To the senior author has fallen the task of establishing some localities with more precision and of narrating on his own experiences with Mormolyce phyllodes Hagenbach while on a collecting trip to the Malay Peninsula, these field notes having, in fact, initiated the studies presently carried out. However fragmentary, the above investigations put together may, it is hoped, contribute in some measure to our knowledge of Mormolyce generally.\nMuch of the material which forms the basis of this paper is lodged in the Rijksmuseum van Natuurlijke Historie, Leiden. Other specimens were made available for study by the authorities of the British Museum (Natural History), London; the Zoologisch Museum, Amsterdam; and the University Museum, Hope Department of Entomology, Oxford. The writers are indebted to Mr. P. H. van Doesburg Sr., Baarn, for supplying locality records of beetles in his collection, and also to Messrs. M. A. Donk, of the Rijksherbarium, Leiden, and C. A. W. Jeekel, of the Amsterdam Museum, who both gave important information on the nomenclature of bracket-fungi and epizoic Laboulbeniaceae.

Description: Weinig onderzoekingen hebben in zo wijde kring bekendheid verworven als die van onze landgenoot JAN SWAMMERDAM, die in zijn ,Ephemeri vita\xe2\x80\x99 (1675) en later in de ,Bybel der Natuur of Historie der insekten\xe2\x80\x99 (1737) de ontwikkelingsgeschiedenis beschreef van het beroemd geworden Oever-aas, Palingenia longicauda (Oliv.), de grootste palaearctische Ephemeride.\nDit allermerkwaardigst insect, dat \xe2\x80\x94 het zij terloops opgemerkt \xe2\x80\x94 reeds in 1634 door de Amsterdamse medicus AUGERIUS CLUTIUS was beschreven en afgebeeld \xc2\xb9), moet destijds in ons land alom de aandacht hebben getrokken wegens zijn massaal optreden gedurende een aantal warme dagen omstreeks het midden van de maand Juni. In Nederland echter is dit grote haft vermoedelijk reeds tegen het eind van de vorige eeuw uitgestorven. Thans leeft het nog in het stroomgebied der grote rivieren van Midden- en Oost-Europa (Oder, Weichsel en Wolga).

Description: During a nine week\'s sojourn in the Malay Peninsula, from February 12 until April 22, 1963, I have been able to acquaint myself with the insect fauna of that country and to make a special study of the Odonata and their larvae. The present account is the first of a series dealing with the results of this collecting expedition. It merely contains descriptions and illustrations of a few new and insufficiently known species of Gomphidae; more of these pertaining to the same family will, it is hoped, soon follow. The rich and varied supply of material accumulated during the Malayan trip forms the basis of this study, but specimens from other sources are incorporated wherever this was found appropriate or necessary. Thus it includes re-descriptions of types in the British Museum collection (BM) and the University Museum of Michigan, Ann Arbor (UMMZ), as well as notes on some valuable larval forms collected in the Plus River area (Perak) given to me long ago by Mr. M. W. F. Tweedie, at one time director of the Raffles Museum, Singapore. More recently, interesting samples of larvae from Johore and Pahang, collected for the Department of Zoology, University of Singapore, were sent to me for study by Dr. D. S. Johnson and his assistants.\nIn this paper only passing mention is made of the habits, local distribution and larval development of the Odonata. Several more will be reared and information on the life-history obtained under natural conditions in the field, will be supplied by my companion, Mr. J. I. Furtado, of the Zoology Department, University of Malaya in Kuala Lumpur. Attention will be paid by him in particular to various aspects of the natural history of Malayan dragon flies in connexion with ecological factors.\nThe following species are discussed in this paper :
