    Notes: Summary Level of social organization, adult behaviour, size and development of the brood in three species ofAnischnogaster are described. The normal colony size in all the three species was one female per nest, and colony size never exceeded two females per nest. The social interactions, which were only observed in one species, did not include any marked dominance behaviour, but there was clear caste differentiation, with the older female guarding the nest while the younger female foraged for food. InAnischnogaster sp. A only some eggs and larvae have abdominal secretion, while no secretion at all was found on the eggs and larvae ofA. laticeps. In spite of this, the Dufour's gland was found to be well developed. The significance of this is discussed. Females ofA. laticeps were found to fall into two groups distinguished by the length of the sting. The larvae seem quite similar to those of other Stenogastrinae and have, apparently, only four instars.

    Description / Table of Contents: Resume Les nids de la GuêpeParischnogaster mellyi que nous avons étudiés étainent faits de longues et minces lnières de végétation morte suspendue. La structure du nid variait du rayon simple à des cellules dispersées le long de la lanière suspendue. La structure la plus fréquente était un nid étiré avec un minimum de parois communes aux cellules. Dans un nid suspendu sur une grande langueur, la première cellule était éloignée des deux extrémités. Ensuite, l'agrandissement s'était fait au dessus et au dessous de cette première cellule. L'avantage du nid long et étroit pourrait être que le nid est ainsi caché des prédateurs qui chassent à vue. Les matériaux de construction sont des cuticules de plantes et des tiges de bois. Ils se présentent sous forme de mietters et de paillettes. Ils sont donc fragiles et non appropriés à la construction de grands nids. Il est possible que le limites physiques des matériaux de construction utilises par les Guêpes Sténograstrines aient pu empêcher l'évolution de colonies de grandes dimensions.
    Notes: Summary Nests ofParischnogaster mellyi were built upon long thin strands of hanging dead vegetation. The nest design varied from a single comb structure to cells spread along the length of the suspension. The preferred nest design was found to be an elongate nest with minimal cell was sharing. On a long nest suspension the first cell was placed remote from either end. Subsequent nest expansion extended both above and below this first cell. It is suggested that advantage of a long, narrow nest may be concealment from visual hunting predators. Nest material is composed of plant cuticle as well as woody stems. It has a composition of fine crumbs and flakes; in consequence it is fragile and unsuited to the large nests. It is suggested that the physical limitations of the nest material in stenogastrinæ may have inhibited the evolution of large colony sizes.

    Brood development in the subsocial waspParischnogaster mellyi (Saussure) (Stenogastrinae, Hymenoptera) (1982)

    Description / Table of Contents: Resume Les durées du stade-œuf, des stades larvaires et du stade nymphal ont été mesurées chez la GuêpeParischnogaster mellyi dont la durée moyenne de développement est d'environ 53 jours. Les mesures de largeur de tête laissent penser qu'il y a seulement 3 ou 4 stades larvaires. Les œufs sont déposés dans la cellule au moyen des pièces buccales. La sécrétion blanche qui accompagne les œufs et les jeunes larves de Sténogastrine provient de l'extrémité du gaster. La glande de Dufour est peut-être la source de cette sécrétion. Nous avons observé que le nombre de mâles est en corrélation positive avec la quantité de couvain. Une proportion importante de couvain a disparu, apparemment surtout à cause du cannibalisme des membres de la colonie. Le nombre maximum d'œufs et de larves dont peut s'occuper une femelle est de 8 ou 9.
    Notes: Summary The duration of the egg, larval and pupal stages ofParischnogaster mellyi was established and the mean duration for the whole developmental sequence was found to be about 53 days. Evidence from larval head-widths suggested the presence of only 3 or 4 larval instars. Eggs were observed to be placed in the cell with the mouthparts. The unique white secretion which accompanies stenogastrine eggs and young larvae was observed to be produced from the tip of the gaster. The Dufour's gland is proposed as a possible source of the secretion. The number of males per nest was found to be positively correlated with brood size. A considerable proportion of the brood (84 %) was lost, the majority apparently through cannibalism by colony members. The maximum number of eggs+larvae that a single female could look after was found to be 8 or 9.

    Notes: Summary Males ofAnischnogaster laticeps andStenogaster concinna possess clusters of glandular class III cells (Noirot and Quennedey, 1974) under the anterior edge of the 3rd gastral tergite. Their morphology is described with the help of histological sections and SEM investigation.

    The selection of resting positions by Anopheles gambiae and Culex pipiens fatigans and the function of the metathoracic legs (1970)

    Description / Table of Contents: zusammenfassung Im Sudan findet man Anopheles gambiae oft in Nomadenzelten an den rauhen Flächen aus Ziegenwolle. Culex pipiens fatigans sitzt dagegen bevorzugt in Häusern an den Wänden. In einem Wahlexperiment wurde gezeigt, daß Anopheles gambiae einer grobstrukturierten Oberfläche gegenüber einer glatten den Vorzug gab. Amputation der Hinterbeine beseitigte diese Präferenz. Culex pipiens fatigans zeigte weder vor noch nach Hinterbeinamputation eine Bevorzugung rauher oder glatter Oberfläche. Als Erklärung wird vorgeschlagen, daß wirbelnde Bewegungen der Hinterbeine, die bei Anopheles gambiae, aber nicht bei Culex pipiens unmittelbar nach dem Landen zu sehen sind, dazu dienen, die Substratbeschaffenheit festzustellen.
    Notes: Abstract Anopheles gambiae were shown to prefer a rough textured to a more smooth textured surface, but this preference was lost after amputation of the metathoracic legs. Culex pipiens fatigans showed no preference for rough or smooth textured surface either when intact or after amputation of metathoracic legs. It is suggested that leg-waving, on landing, which is shown by Anopheles gambiae, but not Culex pipiens is used to determine the texture of the substrate.
