matter, and has never been seen by me carrying seeds. Nest in the ground. (Mentone and Cannes.)
(4) F. (Camponotus) marginata, Latr.—Large (4 to 5-1/2 lines), black. Has no perceptible smell even when crushed. Lives principally on sweet secretions, and does not bring in seeds to its nest, which is made in the ground. I have seen this ant at Cannes ascending the cork oaks in search of certain cocci which resemble black and shining berries rather larger than a pea, and which exude sweet secretions. (Mentone and Cannes.)
(5) Formica cursor, Fonscol.—A rather large but slender ant (3 to 4 lines long), nearly black, with a faint bronzy hue, legs very long. Smell not noted. Runs very swiftly, and is hard to catch; feeds on sweet secretions, and does not carry seeds. Nest in ground. (Cannes.)
(6) F. (species undetermined).—A large ant (5 to 6-1/2 lines), black brown with yellow thorax and legs. In shape resembles F. marginata. Strong smell of formic acid. Habits not observed. Nest found under a stone in a pine wood. (Cannes.)
(7) F. (species undetermined).—A rather large ant (3 to 4-1/2 lines), resembling F. fusca, but having the thorax yellow. Strong smell of formic acid. Feeds on sweet secretions, and does not carry seeds. Nest in ground. (Cannes.)
(8) Formica (Tapinoma) erratica, Latr.—Rather small (2 lines), nearly black. Has a strong and most disagreeable smell, something like rancid oil, which is emitted if the nest is disturbed or the insect crushed. Lives upon sweet secretions and animal matter, but rarely if ever carries seeds, and pays no attention to them if placed in its path. It nests in the ground, and forms superficial covered ways, roofed in with a thin crust of earth and vegetable fibres cemented together. (Mentone, Cannes.)
Tribe Myrmicineæ. Petiole two jointed, furnished with two nodes (protuberances).
(9) Crematogaster (Myrmica) scutellaris, Oliv.—Of medium size (3-1/2 to 4 lines), nearly black, with yellowish red head. Disagreeable smell like rancid oil when crushed. Erects the abdomen when excited, and runs about with it turned up at right angles to the body. Lives on sweet secre-
