Hab. Brazil (Villa Nova).

All the sexes of this species were found by Mr. H. W. Bates in their formicarium, the chambers of which were excavated in dead twigs. The male is 2 1/2 lines long, and of a fusco-testaceous colour, the face, clypeus, mandibles, antennae and legs being pale testaceous; the wings are colourless and beautifully iridescent. The female is of a reddish-yellow, with the eyes, the ocelli, the basal margin of the first segment of the abdomen, and the two apical segments, black; the head elongate, with the sides parallel. The worker is of the same colour as the female, but the metathorax and abdomen are slightly fuscous, the femora are also more or less fuscous; the head is oblong, slightly narrowest behind, the eyes large, ovate and black.
