(50). Common, in open or shady ground. Communities of four or live to twenty - rarely larger - to one hundred individuals. The formicarium is a simple cavity under a stone or stick, at the roots of grass, or occasionally in rotten wood. The ants are very sluggish, hardly moving when disturbed. I have not found the workers in beating foliage, and judge that they are nocturnal, and probably terrestrial, in their habits. I have perhaps included more than one species under this number. Those found in a nest are always of. the same colour, or nearly so; and, though the colour may be due to age, it is singular that there should be no variation in a community. There seem also to be differences of size and form; but my object in separating the species is simply to get better notes on them, and of course the work is very roughly done. I have found these ants crawling, towards evening, on the floor of a dark outhouse. They move slowly.
