The female is a little larger than the female of the typical megacephala , with the head and thorax more sharply sculptured and the color of the body, including the clypeus and mandibles, darker, almost black; the legs more yellowish, as in the worker. This is the host of the singular workerless parasitic ant, Anergatides kohli , recently described and figured by Wasmann from the vicinity of Stanleyville.2
