variety. It differs however in its smell, which, when the body is crushed, resembles that of Pheidole megacephala, and is something like aniseed. Habits of structor and barbara. Nest in earth. On one occasion I opened a large nest at Cannes, where the colony was composed in about equal parts of ants which in colour and appearance might be said to represent the three forms, structor, barbara, and the red-*headed variety of the latter. There were also a few ants with pale yellowish brown heads. (Mentone and Cannes.)

The following Indian species are described by the late Dr. Jerdon as harvesters, in the Madras Journal Lit. and Sc. 1851:—
(p. 45). Atta rufa.—"Its favourite food is dead insects and other matter, but it also carries off seeds like the Œcodoma, chaff," &c. &c. (p. 46). Œcodoma providens.—"Their common food I suspect to be animal matter, dead insects, &c. &c., which at all events they take readily, but they also carry off large quantities of seeds of various kinds, especially light grass seeds, and more especially garden seeds, as every gardener knows to his cost. They will take off cabbage, celery, radish, carrot, and tomato seeds, and in some gardens, unless the pots in which they are sown be suspended or otherwise protected, the whole of the seeds sown will be removed in one night. I have also had many packets of seeds (especially lettuce) in my room completely emptied before I was aware that the ants had discovered them. I do not know, however, if they eat them or feed their larvæ on them, though for what other purpose they carry them off I cannot divine. I have often observed them bring the seeds outside their holes, as recorded by Colonel Sykes, and this I think generally at the close of the rainy season; but in some cases I had reason to believe that it was merely the husks, of which I have seen quite heaps, and that the ants did not take them back to their nests. If any of the forementioned seeds be sown out at once in a bed, most likely in the morning the
