117. Formica cognata . B.M.

Worker major. Length 5 1/2 lines,-Extremely like F. maculata , which it may be; the antennae and head as in that species; the legs entirely ferruginous; the abdomen entirely black; in other respects the same as in F. maculata .

Worker minor.-This insect differs from the small worker of F. maculata : the head is of a different form, being narrowed slightly behind the eyes, and is more sharply emarginate behind; the scale of the peduncle is more elongate and pointed at the apex; the abdomen entirely black, and the legs red. Notwithstanding the differences pointed out, this species will probably prove to be a variety of r. maculata .

Hab. Port Natal.
