Thorax, petiole, and postpetiole indistinctly and loosely punctate rugulose, the prothorax transversely; epinotum with fine, dense but shallow punctures, so that the surface is more opaque.

and might be regarded as a subspecies, but it will fit neither Mayr's description of the typical form from South Africa nor Santschi's and Forel's descriptions of the various subspecies from East and West Africa. Mr. Lang's note shows that it is a harvester. '' The nests were found on a dry hilt at the Post of Zambi in rocky soil. One of the entrances, the largest of three, can be distinctly seen in the photograph (Plate VII). The ants excavate their nests in the small amount of soil between the rocks and all or nearly all of them remain under ground during the day. They work during the night up to about 8 A.M. Then the workers may be seen moving along in files, accompanied by the soldiers, and the latter carry seeds for a distance of some fifteen yards. They come and go in different directions indicated by runways left between the accumulated masses of debris and distinctly visible in the photograph. The debris, consisting of seeds and chaff, lies about the nest to a depth of four centimeters and over an area of some sixty centimeters. It is very difficult to obtain a view of the interior of the nest on account of the rocky soil. Some of the kitchen-middens about the nest entrances contained the dried remains of various ants and Coleoptera. In another locality the same species of ant was seen to have collected seeds of entirely different plants but of about the same size.&quot;
