| Since the publication of my catalogue of Agaon Dalman (Wiebes, 1968) and the key to its species (Wiebes, 1969), several new samples were collected, both in West and East Africa and in Malagasy. In the present paper five new species are described, and keys are given to the species of the two groups recognized in 1969. For bibliographical data reference is here made to the papers mentioned above. The genus Allotriozoon Grandi, not revised since its original description by Grandi (1916), is treated in more detail than is Agaon. One name is synonymized, and one new species is added to those already known for more than fifty years; the knowledge of their distribution is considerably enlarged. Acknowledgements are due to those who collected the samples and sent... |

| Landmarks on the distal segments of the female Chalcidoid gaster are the spiracular peritremata of the eighth urotergite, and the pygostyli of the ninth. The eighth and ninth sterna bear the first and second valvulae, which form the effective ovipositor and its sheath, respectively. The ninth moreover bears the third valvulae, commonly called the valves of the ovipositor. Most Chalcidoid Hymenoptera of the family Torymidae have a long ovipositor, in some instances several times as long as the body. Comparative study of fig wasps of the subfamily Sycophaginae shows that the great length of the ovipositing organs in different groups, may have been acquired by different means. The characters of these structures of the females appear to be correlated with... |

| 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 “classical” 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... |

| The collection of Cetoniid Coleoptera in the Rijksmuseum van Natuurlijke Historie at Leiden contains, next to the usual assortment of chafers from various sources, several collections made by well-known specialists. Most important is the one made by F.T. Valck Lucassen (including the collection of O.E. Janson), acquired by the museum in 1940. A world collection of Cetoniidae is being arranged on the basis of this Valck Lucassen material. In 1928, the collection of G. van Roon was bequeathed to the museum, where it is to remain as such, not incorporated in the main collection. The data of the collection will be presented in this and forthcoming parts of a catalogue, accompanied by such revisional notes which it seems desirable to publish. Reference is here... |

| In 1964, by awarding to me that year's proceeds of the "Pieter Langerhuizen Fonds", the Hollandsche Maatschappij der Wetenschappen enabled me to study figs and fig wasps in the Philippines. While several Philippine fig wasps are already known from the papers by Ashmead (1904, 1905), Brown (1906), Baker (1913), Williams (1921, 1928), Grandi (1927, 1930), Baltazar (1966), Wiebes (1963, 1966a, b, 1967a, b, and 1974) and Hill (1969), the collection made in 1964 and 1965 still contains much new material. In this and forthcoming reports I shall include data on the collection made by F. X. Williams, received in loan from the Hawaiian Sugar Planters' Association, Honolulu (abbreviated HSPA), and on several lots of material sent for identification by: the American... |

| INTRODUCTION In this paper the species of spiders belonging to the families Lycosidae and Pisauridae, known from the Netherlands, are described and figured. In addition a number of species, which possibly may occur in the Netherlands though they have not yet been found here hitherto, are mentioned in the keys. In order to make the keys useful also for identifying immature specimens, I have based these keys not only on the well-known differential characters in the adult sexual organs, but also, as far as possible, on characters derived from colour-pattern and chaetotaxy. The system of notation, used to indicate the situation of the spines on palps and legs, is briefly stated as follows (Wiebes, 1956, pp. 408, 409) : d, 1', 1", v', and v" indicate dorsal,... |

| De soorten van het genus Cyphon Paykull, vooral die uit de verwantschap van C. variabilis (Thunberg), zijn zeer moeilijk op uitwendige kenmerken te determineren. Dit kan eigenlijk alleen met verse of zeer schoon geprepareerde exemplaren. Goede kenmerken zijn echter te vinden in de copulatieorganen 1), zowel bij de mannelijke als bij de vrouwelijke individuen. Bij de mannelijke organen ziet men in ventraal aanzicht de volgende onderdelen (fig. 1) : het negende sterniet (s), de ventrale (ν) en de dorsale (d) plaat van de aedeagus, en daarnaast, bij de meeste soorten, de staafvormige zijkanten van het achtste en negende tergiet (t). Bij het vrouwtje bezit de „prehensor", een chitineus orgaan in de vagina dat dient om de spermatophoor op te nemen, goed... |

| INTRODUCTION In this catalogue — entitled "provisional" because our knowledge of the subject is still so evidently incomplete — all species of Ficus mentioned as hosts of fig wasps, are listed with the Hymenoptera Chalcidoidea reared from their receptacles. The names used for the Agaonidae are in accordance with those in Grandi's (1963b) world catalogue of this Chalcidoid family, two items excepted for nomenclatorial reasons, viz. Blastophaga (B.) inopinata and B. (Eupristina) jacobsoni. Blastophaga (B.) puncticeps distinguenda Grandi (1916a: 129), if considered conspecific with B. (B.) inopinata Grandi (1926: 355), should be called B. (B.) d. distinguenda Grandi, while B. (B.) puncticeps sensu Grandi (1916a: 129) not Mayr (1906: 156), should be indicated... |

| The genus Eujacobsonia, with its type species E. mirabilis, was described by Grandi (1923, 1924) from three female specimens caught at light in Sumatra. Many more examples from the same locality, Fort de Kock ("Bukittinggi", ca. 100 km north of Padang), were recorded by Grandi in 1928. Eujacobsonia was classified by Grandi in the tribe Sycophagini (Agaoninae), which, as was recently suggested (Wiebes, 1961), should be regarded as a subfamily in the Torymidae. Joseph (1964) accommodated the genus in the nominate tribe Sycophagini, but in the same year (Wiebes, 1964) it was referred to the Otitesellini. Recent material in the collections of the Rijksmuseum van Natuurlijke Historie, Leiden (RMNH) was reared by Prof. E. J. H. Corner from the receptacles of... |

| Recently, I received a sample of fig wasps from Uganda (East Africa), collected by Mrs. Ir. W. A. Rijks-Jongbloed in November, 1960. The fig, from which the insects were taken, was recognized by Dr. Gordon P. DeWolf as belonging to Ficus brachypoda Hutchinson1). The sample consisted of two species of Agaonidae, viz., Agaon paradoxum (Dalman) Grandi, and Seres armipes Waterston; moreover several species of Idarninae were represented. The Agaonid species were known from West Africa only2), where they seem to be rather constant in their characters. It is interesting to establish the fact that the species also occur in East Africa, where, however, they differ significantly from the West African forms. The East African forms are described here as separate... |

| This paper is a tribute to Prof. Dr. L. D. Brongersma, in remembrance of the years I served as his deputy in the Rijksmuseum van Natuurlijke Historie. The genus Alfonsiella was described by Waterston (1920) for A. fimbriata, a series of females of which were collected at Dar es Salaam, Tanganyika. In 1959, Joseph recorded females of A. fimbriata from Mt. Nimba, Guinea, and from the same locality he described A. longiscapa. Wiebes (1969) recorded A. fimbriata from Bingerville, Ivory Coast. More female specimens of both West African forms were caught at light by Dr. J. T. Medler at Ile-Ife, Nigeria; females and males of A. longiscapa were reared by him from the receptacles of Ficus cf. leprieuri. Dr. D. S. Hill, when at Makerere University, Uganda, obtained... |

| The study of many new samples of fig wasps collected in Africa by Dr. J. Galil of Tel-Aviv University, Israel, revealed the unexpected fact that Ceratosolen arabicus Mayr and C. galili Wiebes develop together in the same receptacles of Ficus sycomorus L. Dr. Galil made experiments on the host relations of these species and other inhabitants of the Sycomore receptacles, the results of which will be published by him. The identification of the Agaonidae and the Torymidae Sycophagini from Dr. Galil's catches, and some notes on their distribution, are given in the present paper. Unless otherwise indicated, all samples here recorded were reared from Ficus sycomorus L. (det. Galil). The insect material is preserved in the Rijksmuseum van Natuurlijke Historie... |

| After having given for publication my report on the West African Agaonidae (Wiebes, 1969b), I received on loan the type specimens of several species described by J. Risbec (1951a, b; 1954a, b). A few lines on the results of the study of these specimens could be incorporated in the proof of my paper previously mentioned. Formal type designations and some additional remarks on the Agaonidae described by Risbec (1955, 1956) from East Africa and Madagascar, are given in the present note. A summary is presented in table 1 (page 8). During a short visit to the Muséum National d'Histoire naturelle at Paris (abbreviated MP in the text), I could study some more slides of the Agaonidae, and examples of the greater part of the Torymidae Sycophaginae described or... |

| A sample of fig wasps from New Caledonia, sent to me by Mr. E. J. H. Corner, contained a species of Blastophaga Gravenhorst (Agaonidae) and a species of Sycobiella Westwood (Torymidae). The insects were reared from the receptacles of Ficus dzumacensis Guillaum. The Blastophaga is of interest because it is the first record of a fig wasp from any Ficus of the section Oreosycea. The species of Sycobiella is the first to become known in both sexes. Sycobiella boschmai sp. n. Series ♀, ♂, ex Ficus dzumacensis Guillaum. (det. E. J. H. Corner), Mt. Kogi, New Caledonia, leg. H.
