40. Formica rufoglauca ^HNS, N. S.

Worker, 7 - 24 th inch long, head long, oblong; eyes large, pos-terior; jaws strongly toothed; thorax not grooved; abdominal pedicle raised, conic, wide above; abdomen fine silky glaucous green; head, thorax and legs bright rufous.

Warrior, 9 - 24 th inch long, head large; eyes much smaller; antennae shorter; abdominal pedicle flattened posteriorly; abdomen snort and triangular; colour similar.

I have found this Ant only in the Carnatic in small societies living in holes in the ground.

It is possible that this' may turn out to be Fabricius species cinerascens ^HNS.
