Closely related to P. ulysses Forel, but distinct in epinotal structure and in the form of the petiolar spines, which are not as long and are very much less divergent than in that species. The thorax is also much more shining in osae than in ulysses. Type.— M. C. Z. 9, Fig. 56.— Polyrhachis (Myrmatopa) osae Mann. Worker. Petiole from front. This species, which is named for Mrs. Osa Martin-Johnson, the first American woman to travel in the Solomons, is a characteristic species of the extreme eastern end of the group. The nests, built on leaves, usually on palm trees, are of carton, strengthened and lined, as well as fastened to the leaf by silk, and are very common objects in the forest. If a leaf bearing a nest is broken off and laid on the ground the ants rush out, but soon enter the nest again and will remain there, even though the nest be placed in a coat pocket and carried. I examined large numbers of nests of this, as well as other species of Polyrhachis, in search of inquilines, wnthout finding any. On several occasions I found two dealated females of osae, together with larvae, in very small nests, which indicates that the colonies are sometimes started jointly by more than one queen.
