The following note accompanies the specimens from Faradje: "These long-legged ants are very fond of sugar or anything sweet, such as fruits, etc. They are seldom seen during the daytime. The colony had made its nest between boxes that were piled up on the verandah of a house, and the ants were assembled in a hollow space about half an inch wide. A few fibrous particles of detritus were used in the construction of the nest." There are no data accompanying the two specimens from Garamba, so that I am not certain that the female is cospecific with the worker.</paragraph>

is very peculiar in the small, narrow head of the maxima and the long neck-like occipital region of the minima. There can be no doubt that what I have described as the maxima is really the largest worker form. Fifteen specimens of the series all agree in the shape and size of the head as represented in the figure; the remaining specimens are all minimae. Mediae, apparently, do not exist.
