24. Odontomachus rufus ^HNS, N. S .

Worker, length l- 4 th of an inch; head bulging at the sides, narrowed in front; eyes of moderate size; anterior antennae rather long, slender; jaws closely approached at their base, long, linear, with three strong pointed teeth at the end; thorax narrow; abdominal pedicle raised, pointed and conic; abdomen long, oval; head, thorax and legs rufous; abdomen dark brown.

I obtained this Ant under stones in a jungle in the Salem dis-trict, and know nothing of its habits.

I have since obtained one individual also in the Wynaad which may be the Warrior of this species - if the society consist of different individuals. It is 11 - 24 th of an inch long, and appears only to differ, besides its larger size, in having the eyes smaller, and more advanced, the teeth of the jaw blunt, and the thorax finely striated.
