Abstract

Sections of the text are on the systematics and the fully illustrated morphology of the species (with description of N. dalbergiae n.sp.), postembryonic development of the individuals, formation of the soldier caste, details of swarming habits, sex attraction, and foundation of new colonies (in old snags at some height in standing trees), method of estimating the approximate age of the colonies, factors controlling the appearance of sexuals, peculiar 2nd instar larva with thoracic lobes in mature colonies (still unexplained), advanced habit of using excrement for such purposes as building. Graphs show the course of development of the colonies during the first 21 years (in artificial nests and in the forest), the rapid growth to about the 6th year (top size 2800 individuals), and the ensuing natural decline. Twenty plates with 50 illustrations cover the outward appearance of infested trunks, devices for caging nests on trees or severed from the trunk and placed in the open; cross sections of infested portions, breeding experiments in specially constructed artificial nests, the 7 larval and nymphal stages, soldiers of different size and their pseudonymphs, neoteinics, a complete incipient colony, method of trapping sexuals, experiments on the radius of flight, predators and inquilines.
* The species has since been classified as Neotermes tectonae Damm.
