have the general structure and large corrugated bodies of the mature queens. The typical white ants’ nest, known as a Termitarium, usually consists in the first instance of a mass of woody laminated material that might be likened to papier-mache, originally a stump or portion of a log that has been chewed up and voided in the form of a mortar-like substance. This termitarium is full of irregular galleries running like a network all through the mass, with the means of exit running out under the nest; a mass of stout terraced structure above the ground level surrounds the Royal Chambers, which might be likened in size and shape to an inverted saucer, from which the enclosed Queen cannot escape, but the attendant workers can pass to and fro. Above this is a rounded oval mass often as big as a child’s head, which resembles stiff brown paper folded round and round, full of fine openings, and is easily crumbled up; this, for want of a better word, I call the nursery, as it contains all the minute larvae as they emerge from the eggs. The formation above the nursery is more irregular, and terminates in a rounded cap. The whole of this woody structure is covered with a stout enveloping wall of fine clay, which, carried up grain by grain, has been cemented together into a firm earthy wall in contact with the woody structure at the base of the nest, but often with a cavity at the apex.

(“Agricultural Gazette,” N.S.W.)] The nests of the _Eutermes_ are sometimes built over stumps, but more often on the branches or trunks of trees, where they form rounded or oval masses a foot or two in diameter, with covered galleries leading down to the ground. In these nests there is no distinct outer earthy sheath; when near the ground, earth and wood are blended together in a very compact mass, full of small galleries running at every angle, and have no distinct structure like the first group. When the nest is placed on a tree trunk or branch away from the ground it consists almost entirely of woody matter, and may be quite soft and papery beneath the outer crust. In the West Indies these nests are popularly known as “Negroheads.” Other groups are never known to construct true nests, but form chambers and galleries under the bark of trees, in banks, or simply under logs and stones. Some in the interior are said to disappear underground from their nests in the dry summer time, returning with the first rains and mending up the dilapidated walls. The members of the two genera _Mastotermes_ and _Calotermes_ have the wings much more thickly veined than the more simple _Termes_ and _Eutermes_.
