    The geographic variation of Polistes (Megapolistes subg. n.) rothneyi Cameron (1968)
    In:  Bijdragen tot de dierkunde vol. 38 no. 1, pp. 97-109
    Details
    Publication Date: 2024-01-12
    Description: The species discussed in this paper has been generally misidentified by previous authors. BINGHAM (1897) and DOVER (1929, 1931) confused it with the closely related P. hebraeus (F.) (a junior synonym of P. olivaceus (DeGeer)). Bequaert correctly separated this species from its close relatives (P. olivaceus and P. jadwigae Dalla Torre), but unfortunately he did not publish his conclusions. Specimens in various collections have been labelled by him as P. jokahamae Radoszkowski, 1887, a name that has also been used by Japanese authors (SONAN, 1943; TSUNEKI, 1957, 1962; YOSHIKAWA, 1962; mostly emended as \xe2\x80\x9cyokohamae\xe2\x80\x9d). The original description of P. jokahamae, however, does not apply to the present species and leaves no doubt that Radoszkowski\xe2\x80\x99s species must be regarded as a synonym of P. japonicus Saussure, 1858. The oldest available name for oui"" species appears to be P. rothneyi, proposed in 1900 by P. CAMERON for a male Polistes from Barrackpore, Bengal. In the same paper Cameron described the female from Assam, but he did not recognize it as being conspecific with rothneyi and called it rufolineatus.\nPolistes rothneyi belongs to a group of closely related species which appears to deserve subgeneric rank. The name proposed here for this group is taken from Dr. J. Bequaert\xe2\x80\x99s unpublished notes, now preserved in the U.S. National Museum and kindly made available to me by Dr. Karl V. Krombein.

    Hymenoptera Sphecoidea Fabriciana (1961)
    In:  Zoologische Verhandelingen vol. 48 no. 1, pp. 1-82
    Details
    Publication Date: 2024-01-12
    Description: INTRODUCTION\nIn the early years of systematic entomology Johann Christian Fabricius (1745-1808) described an enormous number of insects, including several hundreds of Hymenoptera, from various parts of the world. His descriptions are generally short and incomplete, the classification of the species is often unsatisfactory, and the author himself frequently misidentified species which he had described in previous works.\nHis work has thus raised a considerable number of problems, which in most cases can be solved only by a study of the typical specimens. Workers in some insect groups have realised this at an early date, and by a detailed study of the Fabrician collections they have made important contributions to our knowledge of many doubtful species. A good example is C. St\xc3\xa5l\'s excellent work "Hemiptera Fabriciana", published in 1868 and 1869.\nThe Hymenoptera, however, have received only relatively little attention, and even European monographers have generally neglected to clarify the position of the Fabrician species by the study of authentic material. A notable exception is A. G. Dahlbom, who identified, aided by Prof. Behn in Kiel, the types of several Sphecoidea and Pompilidae on behalf of his "Hymenoptera Europaea" (1843-5). In 1912 W. A. Schulz examined a number of doubtful species, and in later years certain types have been studied in connection with investigations made by Turner, Betrem, Richards, de Beaumont, Lieftinck, and others. Yet a considerable number of species has never been identified by competent specialists, including some species which have been a real or potential source of confusion and misunderstandings for over 150 years.

    Description: Sedert 1923 zijn door mij een groot aantal gegevens omtrent de verspreiding van onze geangelde Hymenoptera bijeengebracht.\nHet was mijn bedoeling deze in den loop van den tijd aan te vullen en te verwerken tot eenige nieuwe naamlijsten van die families, waarvan tot nu toe slechts oude en verouderde opgaven bestonden; tot mijn spijt is dit werk door mijn vertrek naar Indi\xc3\xab, in den zomer van 1928, echter niet voltooid kunnen worden en moet ik volstaan met het geven van onvolledige lijsten.\nDoor allerlei omstandigheden is het samenstellen hiervanzeer verlaat; ik hoop echter de Nederlandsche entomologen, die zich voor deze groepen interesseeren (en dat zijn er helaas nog veel te weinig!), toch nog van dienst te kunnen zijn met het publiceeren van mijn aanteekeningen.\nBijna al het materiaal, waarop deze gegevens gebaseerd zijn, berust thans in \'s Rijks Museum van Natuurlijke Historie te Leiden. Bij het determineeren mocht ik veel hulp ontvangen van de heeren H. Haupt te Halle (voor de Psammocharidae), P. BL\xc3\x9cTHGEN te Naumburg (Halictus en Sphecodes) en J. D. ALFKEN te Bremen (Apidae), wien ik hiervoor gaarne mijn dank betuig.\nOver de hier behandelde families wil ik nog het volgende meedeelen: Van de Nederlandsche Mutillidae vindt men een lijstje in de publicatie van Dr. J. TH. OUDEMANS in \xe2\x80\x9eEntomologische Berichten", n\xc2\xb0 42 (1908): \xe2\x80\x9eOnze Nederlandsche Mutillidae."

    On Eumenes Arcuatus (Fabricius) and some Allied Indo-australian wasps (Hymenoptera, Vespidae) (1959)
    In:  Zoologische Verhandelingen vol. 41 no. 1, pp. 1-71
    Details
    Publication Date: 2024-01-12
    Description: In a study on the variation of Polistes and other Vespidae, K. Zimmermann (Zeitschr. Morph. Oek. Tiere, 22, 1931, pp. 173-230) concluded that the variation of the Indo-Australian Eumenes arcuatus (Fabricius) differs in a remarkable way from that of several European species of wasps.\nThe geographic variation of the palaearctic Polistes, Odynerus and Eumenes was found to be strongly influenced by external factors: black pigments increase in cold and humid environments, whereas the yellow pigments dominate in hot and dry areas. According to Zimmermann, there is considerable individual variation in this respect in the palaearctic region, and no constant geographic races have developed here. On the other hand, the Indo-Australian Eumenes arcuatus occurs in a number of clearly separated geographic races in which no influence of climatic factors on the distribution of the black and yellow pigments is recognizable.\nZimmermann distinguished twelve subspecies of E. arcuatus, all differing in colour characters; some of these are widely distributed, others inhabit only a restricted area. Some overlapping of the areas of distribution was said to occur: the Ceylonese flavopicta was recorded as "vereinzelt auf Sumatra und Java" (where this form certainly does not occur!); the Javanese blanchardi was recorded from Sumatra (incorrectly!) and the Saleyer Islands; in the latter locality it was therefore supposed to fly together with the black saleyerensis, described by Zimmermann from these same islands. New Britain was said to harbour both typical arcuatus and the subsp. praslinius.\nZimmermann published a series of diagrams showing the different colour patterns of the various subspecies, and was the first author to distinguish the form inhabiting continental South East Asia and Sumatra (subsp. continen-

That part dealt with the morphology and the distribution of the species which are distinguished by having a more or less distinct raised carina separating the anterior and the lateral areas of the mesepisternum ("mesopleura"). It was my intention to publish supplementary notes on the bionomics of these species, together with a revision of the remaining species, in a second part, but war conditions made this plan fall through. Owing to various circumstances, the work on this subject was not resumed until recently.\nIn the following pages I have first brought together some additional information on the previously discussed species (subgenus Anthreneida White). Unfortunately this chapter is very fragmentary, mainly because the greater part of my collection of nests together with the accompanying notes was lost during the war.

    The Rhynchium species of the Philippine Islands (Hymenoptera, Eumenidae) (1968)
    In:  Zoologische Mededelingen vol. 42 no. 24, pp. 255-259
    Details
    Publication Date: 2024-01-12
    Description: It has generally been accepted that the Philippine Islands are inhabited by only a single species of the Eumenid genus Rhynchium. In Miss Baltazar\'s valuable catalogue (1966) it is listed as a subspecies, atrum Saussure, of R. haemorrhoidale (Fabr.).\nHowever, when in 1963 I examined an extensive collection of Eumenidae from these islands in the U.S. National Museum, Washington ), the available material of this genus proved to consist of two very similar, though readily separable, species. The question thus arose, to which of these should be applied the name atrum Saussure. This species was described from "Les Indes Orientales, les Iles de la Sonde, la Nouvelle Guin\xc3\xa9e [Warou]. (Mus\xc3\xa9e de Paris)". Unfortunately I did not find any specimens of this certainly rather heterogeneous series in the Paris Museum, and I therefore had to rely on a comparison of my material with the original description.\nIt appeared that this description is almost certainly based on one or more specimens from the Philippine Islands, for it applies better to one of my two Philippine species than to any other of a great number of forms from various parts of the Oriental region. In order to establish the identity of R. atrum with certainty, however, I have considered it desirable to designate a neotype for this species.\nThe material discussed in this paper is preserved in the following collections.\nAMNH = American Museum of Natural History, New York, U.S.A.\nBISH = Bernice P. Bishop Museum, Honolulu, Hawaii, U.S.A.\nBPI = Bureau of Plant Industry, Manila, Philippines.\nCNHM = Chicago Natural History Museum, Chicago, Ill., U.S.A.

    A perliminary revision of the Oriental species of the genus Ceratina (Hymenoptera, Apidae) (1952)

    Publication Date: 2024-01-12
    Description: The Oriental bees of the genus Ceratina Latr. are difficult to identify.\nUntil now our knowledge of these insects consisted mainly of a considerable number (about 90) of isolated descriptions, scattered through several scientific journals. Most of these descriptions are based on colour characters and although these are certainly not without taxonomic value, they must be used with great care on account of their intra-specific variability. The structural and sculptural characters which are much more reliable for distinguishing the species have thus far not received sufficient attention.\nThere exist a few keys, dealing with the species occurring in certain parts of the region, but none of these contains more than 11 species and the characters used are often of doubtful taxonomic value.\nAn attempt to identify a large number of species collected in Indonesia, mainly in Java, by Dr. and Mrs. Lieftinck, my wife and myself, soon demonstrated the necessity of a revision of the Ceratina species described from this and other parts of the Oriental region.\nIt would have been completely impossible to recognize the majority of these species with sufficient certainty from their descriptions. Fortunately I had an opportunity to study much authentic material. In September 1951 I examined the types of several species described by Smith, Cameron, and Cockerell in the collections of the British Museum (Natural History) and the Oxford University Museum ; some additional types, preserved in the Rothney collection in the latter Museum, were kindly sent to me for study at a later date.\nThe U.S. National Museum sent me a very interesting collection of oriental Ceratina, containing several species identified by Cockerell as well
