Crematogaster foxi, sp. nov. Worker. Length mm. Head with strongly convex sides, rounded occipital corners and concave border. Mandibles 4-dentate. Anterior border of clypeus straight. Anten- nal scapes extending four fifths the distance to occipital corners; first funicular joint as long as the three succeeding joints; joints two to eight almost as long as broad; terminal joint shorter than the three preceding joints. Eyes large and moderately convex, situated at sides of head posterior to middle. Thorax slender. Pronotum margined at sides, humeri rounded, disc slightly Fig. 23.— Crematogaster foxi Mann. Worker. Lateral view of thorax and petiole. Mesonotum at sides with a narrow elevated margin, the surface shallow, con- cave, and, posterior to middle, sloping to the deep mesoepinotal impression. Epinotum shallowly concave; spines subtriangular, acute, half as long as their distance apart at base and almost straight. Petiolar node slightly longer than broad, narrowed in front, with roimded anterior and angulate posterior corners. Postpetiole a little broader than long, longitudinally impressed above. Gaster elongate. Shining. Mandibles and cheeks striate. Clypeus with one strong and several very feeble costae at sides. Pronotum with longitudinal costae, two of which extend as borders to the mesothorax. Epinotum with indistinct costae. Petiolar node and base of postpetiole microscopically rugulose, the rest smooth. Scattered, very long, and erect yellow pile present everywhere, except on legs and antennae where it is fine and semirecumbent. Color yellow. Female. Length mm. The striation of the mandibles is much coarser than in the worker. The head and body are sm
