(31). A rare species, forming large colonies. Formicarium generally in rotten wood. When disturbed these ants are rather pugnacious. The workers minor are active; the workers major move about heavily. The latter are not numerous.

Formicarium in very rotten wood; the passages extended through six or eight inches of the log, with several chambers, each about 1 x 1 / 2 in. The colony probably contained over 1000 individuals. Immature males were numerous. Only a few females could be found. Nov. 8 th.

(31 b). Hermitage Estate, Cumberland Valley, 1000 ft. Dec. 1 st. Open hill-side near forest. Formicarium in a rotten stick on the ground. It extended irregularly through about 15 in. of the stick, with several chambers, each about 3 / 4 in. long, and half as wide and high. The colony may have contained 500 individuals, the workers major being about one-tenth as numerous as the workers minor. There were many immature males in this nest,. but I could find no female.

(31 c). Same locality and situation as the last, in another log. The nest did not differ from No. 31 b, except that the chambers were rather larger; the community probably contained over 1000 individuals. About twenty winged females were seen, but no males.

(31 d). Upper Richmond Valley, 1500 ft.; forest by a stream; under rubbish near the water. No nest could be found.
