    Notes: Abstract Myrmecia dispar (Clark) is found in the drier inland areas of New South Wales and southern Queensland in Australia. Its nests, which are situated adjacent to trees, have a distinctive structure of simple architecture. The composition of the colonies varies seasonally with little or no brood production during the colder months. Colony founding probably takes place in March, April, and/or May. Several myrmecophiles are found in nests ofM. dispar, and some of these are present in relatively large numbers.

    Description / Table of Contents: Résumé Les ouvrières deMyrmecia froggatti Forel et deM. varians Mayr présentent un monomorphisme avec une faible variabilité de la taille, tandis que celles deM. simillima montrent un dimorphisme avec une considérable variation de la taille. Les valeurs des coefficients de variabilité calculés pour quatre caractères fournissent une bonne mesure de la variation spécifique de la taille. Les histogrammes de fréquence du rapport longueur/largeur de la tête sont unimodaux pour une colonie deM. froggatti et trois colonies deM. varians et bimodaux pour cinq colonies deM. simillima.
    Notes: Summary Myrmecia froggatti Forel andM. varians Mayr workers show monomorphism with limited size variability, while those ofM. simillima exhibit biphasic monomorphism with considerable size variation. Coefficient of variability values calculated for four characters provided a good measure of species size variation. Frequency histograms of head length against head width were distinetly unimodal in one colony ofM. froggatti and three colonies ofM. varians, and bimodal in the five colonies ofM. simillima.

    Description / Table of Contents: Résumé Un grand nombre d'organismes ont été trouvés dans les nids deMyrmecia. Les ordres suivants (avec le nombre d'espèces) sont représentés: Anura (1); Araneae (9); Acarina (1); Blattodea (3); Coleoptera (20+); Collembola (3); Diptera (1); Hemiptera (2); Hymenoptera (14); Isoptera (2); Lepidoptera (4); Neuroptera (1); Orthoptera (2); Thysanura (4+); Isopoda (13) et Nematoda (1). Les plus fréquents sont des Collemboles et des Isopodes, qui ont été trouvés dans la majorité des nids; ils sont surtout détritivores. Des Termites et deux espèces de Fourmis cohabitent, sous forme de sociétés, dans les grands dômes de terre desMyrmecia. Certains des Coléoptères et des Diptères se trouvent, à l'état de larves, dans les chambres à débris, tandis que beaucoup des Coléoptères adultes constituent des proies. Il y a lieu de souligner la présence répétée de grandes larves deCarabidae dans les nids de quatre espèces deMyrmecia.
    Notes: Summary A large number of associated organisms have been found in nest ofMyrmecia; the following orders and numbers of species, in brackets, are represented:Anura (1); Araneae (9); Acarina (1); Blattodea (3); Coleoptera (20+); Collembola (3); Diptera (1); Hemiptera (2); Hymenoptera (14); Isoptera (2); Lepidoptera (4); Neuroptera (1); Orthoptera (2); Thysanura (4+); Isopoda (13) and Nematoda (1). Most abundant were specimens of Collembola and Isopoda which were found in the majority of nests; these occurred principally as scavengers. The termite species and two ant species were found in colonies co-inhabiting the large earthen mounds ofMyrmecia. Some of the Coleoptera and Diptera species occurred as larvae in the debris left in chambers, whereas many of the adult beetles were present as prey. Noteworthy were the several occurrences of large Carabidae larvae in the nests of fourMyrmecia species.

    Description / Table of Contents: Résumé La reine construit un nid très simple selon un modèle commun à la plupart des espèces deMyrmecia. Cependant, après l'apparition des premières ouvrières et à mesure que croît la colonie, la structure du nid change lentement pour devenir typique de l'espèce. Bien que beaucoup d'espèces, sinon toutes, aient un nid de structure typique, deux modèles de base caractérisent lesMyrmecia. L'un est simple et consiste habituellement en une cheminée principale et peu ou pas de dôme. L'autre, moins net et plus compliqué, comporte habituellement trois cheminées, ou davantage, et un grand dôme. Des indications sont données sur l'emplacement, la taille et d'autres caractéristiques significatives des nids. Des précisions sont aussi fournies sur les populations adultes dénombrées dans 56 nids représentant 20 espèces et sur la composition du couvain. La composition de la plupart des colonies a changé en fonction de la saison. Les ouvrières ont été récoltées en plus grand nombre dans les nids à structure compliquée que dans les nids simples.
    Notes: Summary The queen makes a very simple nest structure which appears to be a common design for mostMyrmecia species. However, after the appearance of the first workers the nest structure changes slowly as the colony grows larger to one typical of the species. Although many species, if not all, have a typical nest structure, two basic designs appear evident in theMyrmecia. The first is a simple structure with normally one main shaft, and little or no mound, while the second is a more diffuse and complex structure usually with three or more main shafts and a large mound. Notes on their location, size, and other significant features are given. Details are also given of the adult populations counted in 56 nests representing 20 species and their brood composition. The composition of most colonies appeared to vary seasonally. Larger worker populations were collected in nests with a complex structure than in those with a simple nest structure.

    Description / Table of Contents: Résumé Selon des observations étalées sur 4 mois en forêt tropicale secondaire dans l'île de Penang en Malaisie, les pistes tracées depuis un nid par des Termites noirsLongipeditermes longipes (Haviland) changèrent tous les jours. Les pistes étaient à la surface du sol sur presque toute leur longueur, le long de branches mortes, d'arbustes et d'arbres. Elles s'échelonnaient sur 6 à 39 mètres. Il apparut que l'activité sur les pistes dépendait beaucoup des conditions climatiques, elle fut habituellement nulle par temps de pluie. L'activité la plus importente fut observée de 8 à 11 h 30.
    Notes: Summary Processional trails (foraging expeditions) of the black termiteLongipeditermes longipes (Haviland) from a nest changed frequently during observations in a secondary rainforest on Penang Island, Malaysia, over a four month period. Nearly all of the length covered by the trails was above the ground along dead branches and shrubs and trees. The distance covered by the trails ranged from 6 to over 39 metres. Processional activity appeared to be influenced strongly by climatic conditions and during wet weather none was usually recorded. Most activity was observed in the morning between 8.00 and 11.30 am.

    Notes on the field behaviour of two ant speciesMyrmecia desertorum Wheeler andMyrmecia dispar (Clark) (Hymenoptera: Formicidæ) (1971)

    Notes: Abstract The behaviour ofMyrmecia desertorum Wheeler andMyrmecia dispar (Clark) was studied in the field at intervals during winter and summer from 1963 to 1967. The daily and seasonal pattern and type of activity of the species differed considerably. In winter, the workers foraged in the late morning and afternoon, while in summer they foraged in the early morning and late afternoon. Both species foraged largely on nearby trees. Most of the worker population in twoM. dispar nests left to forage. The diet of both species was very dissimilar in summer when the workers foraged in large numbers. Field observations on orientation suggest that the workers memorize the position of trees on which to forage and that visual stimuli are important for capturing prey. Migration to new abodes by two colonies ofM. desertorum and transportation of workers are described.

    Notes: Summary Myrmecia dispar (Clark) workers and queens show monomorphic polymorphism with limited size variation. Significant differences were found for the mean values of certain characters of workers between some colonies. Frequency histograms of head width against the number of workers in a colony varied considerably, with little or no definite pattern for the smaller colonies and ranging from unimodal to bimodal histograms for the larger colonies. Highly significant, positive, correlation values were obtained for all measured characters in each colony. Partial correlation analysis revealed much of this correlation to be due to similar growth coefficients. Regression analysis indicated that the characters head width and pronotal width were linearly related.

    Notes: Abstract An analysis is presented for a model of a two-species predator-prey system where each species can be harvested or stocked. Using methods from bifurcation theory the qualitative nature of the steady-state solutions is examined. The effect of harvesting and stocking rates and the prey carrying capacity is examined in detail.
