The abdomen is black, the head and thorax deep castaneous, almost black, with the bases of the mandibles, lower surface of the head and concavities of its upper surface, mesopleurae, legs, and antennae somewhat paler and more reddish; in some specimens the tibiae are still paler.

Female (dealated).-Length nearly 15 mm. Darker than the worker, black, with the legs and antennae dark brown. Mandibles smoother and more shining than in the worker. The transverse rugae on the pronotum and the longitudinal ruga' on the mesonotum much coarser than in O. haematoda and the whole thorax more shining. The pubescence is lacking, even on the gaster, which is very shining.

In addition to these, there are thirty workers and one female (the one described above) taken from the stomachs of toads (Bufo polycercus, funereus, and superciliaris) from Medje, Ngayu, Akenge, Boyulu, and Niangara.
