Última Generic characters of the south american Corduliidae, with descriptions of the species found in the Guyanas Naturalis Geijskes, D.C.. This study contains the results of an examination of the Corduliidae found in the Guyanas. It is based on a critical study of the data as published mostly in the older literature and on the identification of the material brought together in Surinam in the years 1940 to 1965 by Mr. J. Belle and myself, beside some specimens picked up in French- and in (Br.) Guyana. Comparison of three types in the Selys collection in the Brussels Museum, of one in the Fraser collection in the British Museum (Nat. Hist.) in London and of one kindly received from the Museum in Berlin was necessary to eliminate further confusion. It now became clear that, so far as the material goes, one genus (here described as new) belonging to the Gomphomacromiinae and two genera of the...

De orde van de netvleugelige insekten of Neuroptera is in Nederland nog weinig bestudeerd. Wij kennen thans ongeveer een 60-tal inlandse soorten, waaronder verscheidene die slechts een enkele maal in ons land zijn aangetroffen. Gedurende het Meijendel-onderzoek bleek deze orde in dit Wassenaarse duingebied rijker te zijn vertegenwoordigd dan was gedacht. De eerste waarnemingen hierover dateren van de twintiger jaren, waarbij in verband met de inventarisatie-pogingen de naam van Dr. H. C. Blote met ere mag worden genoemd. In de latere jaren is het onderzoek lange tijd op dit niveau gebleven. Een winstpunt betekende de belangstelling van J. A. W. Lucas en A. C. M. van Dijk voor deze groep, die tijdens hun vlindervangsten op licht, in de jaren 1957 tot 1963... Tipo: Article / Letter to the editor Palavras-chave: 42.75.

Single female specimens of dragon flies are often difficult to identify owing to the fact that, when they are known at all, the descriptions are incomplete and mostly lack the essential figure of the genitalia. The following are descriptions of the unknown females of five species, the males of which have been known for the last eighteen to fifty years. They are all complete with figures of the genitalia. The material from which the descriptions have been made has been accumulated during many years of collecting. I am indebted to Mr. J. BELLE, Paramaribo, who was kind enough to place at my disposal, for description, some of the unknown females collected by himself.

The large species of the genus Staurophlebia are confined to the neotropics and some to the Amazon-basin in particular. One of these species, Staurophlebia gigantula, was described as new by Martin (1909) after three males and two females present in the De Selys Longchamps collection and probably collected by H. W. Bates in the Amazonas district. With a photograph of the right wing pair of a male, a drawing of the male appendices in dorsal and lateral view and a figure in colour of a male specimen, the species seemed well fixed. It was the second species of Staurophlebia described, and for 50 years it was known from its types only. During my first expedition into the interior of Surinam in 1939, I found near the Brazilian border a species of Staurophlebia... Tipo: Article / Letter to the editor Palavras-chave: 42.75.

De hieronder volgende gegevens zijn gebaseerd op twee belangrijke zendingen insecten-materiaal van Terschelling, die beide in 1967 werden bijeengebracht. In de eerste plaats betrof dit het materiaal dat door vier preparateurs van het Rijksmuseum van Natuurlijke Historie te Leiden was buitgemaakt tijdens een verzamel-excursie van 5-19 juli. De deelnemers waren de heren : C. van Heijningen (leider), Ph. Pronk, W. Planjer en M. J. Delfos. Zij verzamelden in verschillende terreinen van het eiland en maakten op 12 juli ook een dagtocht naar Vlieland. In totaal werden 5372 insecten gevangen, behorende tot de volgende orden: Orthoptera 40, Dermaptera 1, Odonata 110, Heteroptera 455, Psocoptera 2, Neuroptera 39, Trichoptera 10, Lepidoptera 144, Diptera 2309,...

(1) Faunistic insect collecting was done in Suriname from September 1963 to December 1964 with two types of “malaise” traps. (2) Trapping was practised on nine localities in different habitats, operating from the seacoast near Paramaribo via the older coastal belt and the savanna region into the rainforest of the hilly interior. (3) During this operation, a total of about 90.000 insects was collected. There was but little variation in the proportions of the different orders of insects taken in the nine localities. This is explained by the mode of sampling. (4) The catches show the following relative abundance: Diptera 1/2, Hymenoptera 1/5, Lepidoptera 1/7, Coleoptera 1/20, Hemiptera 1/40, Orthoptera 1/50, others less than one percent.

Until recently biological research in the sea off Suriname had not received much attention. There was no fishery in the open sea and there was no incentive to investigate this unknown world. But in the last twenty years, experiments have gradually led to serious study of the subject. Before the second world war, schooner fishing in the open sea to catch red snapper fish, as already carried out off (British) Guyana, was tried by the Curaçao Trading Company in Paramaribo, but this experiment was not a success. During the war, a study of the local fisheries became urgent, to find out how far Suriname was able to supply the people with protein food.

Of the three Guyanas on the north coast of South America, Suriname is the middle one, lying between French Guyana to the east and British Guyana to the west. The frontiers between these three countries are formed by the Marowijne River (Suriname — French Guyana) and the Courantyne River (Suriname — British Guyana). In general the Guyanas are much alike in geographical features — covered with tropical rain forest for the most part and with savannas and swamps for the rest. The freshwater molluscs live in the large rivers and the bush creeks in the hinterland, and in the swamps, canals and trenches in the more or less cultivated coastal plain.

The genus Gynothemis was introduced by Calvert (1909), when describing an aberrant member of the Macrothemini from Brazil. The following characteristics were used for this genus: anal area in hind wing with irregularly arranged cells; one row of cells in Rspl, M2 not undulate; triangle in fore wing free, two rows of cells in discoidal field from triangle to wing margin. Femora in both sexes armed with the usual two rows of spines, those of the male not differentiated. Type species: Gynothemis venipunctata Calvert, from Chapada in Brazil. Ris (1913) added two more species to the genus, viz., heteronycha Calvert, described by the author in Brechmorhoga, and calliste Ris, known from one female only. According to Ris, the three species resemble the smaller... Tipo: Article / Letter to the editor Palavras-chave: 42.75. Ano: 1972 URL: http://www.repository.naturalis.nl/record/318331 The Dragonfly-Fauna of Trinidad in the British West Indies, (Odonata) Naturalis Geijskes, D.C.. The origin of the present paper is based on two large collections of Odonata, recently made in Trinidad. The first one is my own collection brought home from my stay in the island in July and August 1929, containing several hundreds of specimens from different localities. The second one is that of Dr. E. M. WALKER in Toronto Ontario, generously sent to me for examination. It also contains many hundreds of individuals, collected in the island in Sangre Grande by G. BELMONTES in 1930 and 1931. Lateron in 1931 and '32 two sendings of the same collector were received for my collection, by which it was enlarged by some rare and not yet represented species. It may be interesting to know that duplicates of most of the species in my collection are handed over to... Tipo: Article / Letter to the editor Palavras-chave: 42.75. Ano: 1932 URL: http://www.repository.naturalis.nl/record/317908 Three new species of Micrathyria with a note on M. romani Sjöstedt Naturalis Geijskes, D.C.. In the following descriptions, three new species of Micrathyria are introduced. They have been collected during the last twenty-three years of field work carried out in Suriname from the country’s northern Atlantic coast to its southern border with Brazil. Micrathyria surinamensis n. sp. belongs to the aequalis-longifasciata group, M. paruensis n. sp. is a representative of the ungulata-complex and M. coropinae n. sp. shows a close relationship with M. romani Sjöstedt. I am much indebted to Dr. RENÉ MALAISE, Curator of the Naturhistoriska Riksmuseum, Stockholm, for the loan of the type specimen of M. romani, from which supplementary notes and figures could be made.

PART II. Subordo: Anisoptera. Fam. Aeschnidae. Subfam. Gomphinae. Genus: Gomphoides Selys. The little material of the interesting family of Gomphinae we know from this island, is represented by a few specimens of the genus Gomphoides. In the year 1929 on July 13 and some days afterwards, two specimens, one male and one female of different species were taken by myself on a small river in the mountains near Mt. St. Benedict. Since these captures no Gomphoides was seen again, all the time I stayed in Trinidad. Mr. E. B. WILLIAMSON in Michigan, from whom I got information when determining my Gomphoides-specimens, wrote me in this connection, that he was just working at a revision of the genus and not able (March 17, 1930) to name my Trinidad specimens.

A re-examination of the female holotype of Libellula (Oligoclada) abbreviata Rambur (1842) from Cayenne, deposited in the collection of de Selys Longchamps at the Brussels Museum, has brought to light that this is a female of Oligoclada raineyi Ris (1919), described after a single male from British Guiana. It could be compared with a pair captured in copulation of Oligoclada raineyi Ris (1919), from the interior of Surinam. The misidentified male of O. abbreviata discussed by Ris (1911), is now named O. risi spec. nov. A copulating pair of this insect was also found in Surinam and has been used for the redescription of that species.

Ano: 1984 URL: http://www.repository.naturalis.nl/record/319194 Anax longipes versus Anax concolor Notes on Odonata of Suriname X Naturalis Geijskes, D.C.. Of the American species of Anax characterized by an unmarked frons, A. longipes Hagen (1861) was described from U.S.A. and A. concolor Brauer (1865) from the Amazon in Brazil. But soon after their description HAGEN (1890) was of the opinion that concolor Brauer was only a variety of longipes, in which according to him the odonatologists have taken the same stand. This conception is probably due to the fact that insufficient material of both species is studied. The motive for a reexamination of the two species was a comprehensive material of Anax concolor mostly collected in Suriname and on the Lesser Antilles. Additional specimens of A. longipes from the U.S.A. were received for comparison. The type specimens of both species could be examined but the...

Over de libellenfauna van Meijendel is weinig bekend. In het volgende overzicht is gebruik gemaakt van een aantal vroegere gegevens en van recent materiaal, dat in Meijendel gedurende de laatste tien jaren meer gericht is verzameld. In de collecties van het Rijksmuseum van Natuurlijke Historie bevinden zich imagines die tussen 1849 en 1976 te Meijendel zijn verzameld; deze zijn alle in de materiaallijsten van de soorten opgenoemd. Daarnaast is door een onzer (E. J. van N.) bij zijn onderzoek naar de waterwantsen en waterkevers van Meijendel gedurende de periode van 1970 tot 1977, een collectie van ca. 250 libellenlarven bijeengebracht en gedetermineerd. Hiermede kon het broeden van elf soorten libellen in dit duingebied aangetoond worden. Bovendien bleek... Tipo: Article / Letter to the editor Palavras-chave: 42.75. Ano: 1978 URL: http://www.repository.naturalis.nl/record/317195 The Aeschnine Genus Staurophlebia Naturalis Geijskes, D.C.. The genus Staurophlebia was established by BRAUER (1865, 1866) from his species magnifica from Brazil, a name which later proved to be a synonym of reticulata (Burmeister 1839), (see under this species). In his notes on St. magnifica, HAGEN (1867) said that SELYS (MS) has proposed the genus name Megalaeschna for Aeschna reticulata Burm., Ae. gigas Rbr. (= reticulata), and Ae. gigantula Selys, a closely related new species which was subsequently described by MARTIN. However, Megalaeschna is a synonym of the earlier name Staurophlebia, as already pointed out by COWLEY (1935). In his classification of the aeschnines, SELYS (1883) includes the two subgenera Neuraeschna and Staurophlebia in his genus Staurophlebia s.l., while KIRBY (1890), CALVERT (1905), and...
