93. Formica singularis. Worker. Length 6 lines.-Head ovate, red; antennae slender, as long as the thorax, and black; clypeus subcarinate; eyes black and ovate. Thorax black, elongate, narrow, widest in front, and narrowest in the middle; the metathorax convex, evenly rounded from base to apex; the legs elongate; the thorax and legs covered with a fine silky pile, and sprinkled with a few long erect pale hairs. Abdomen black, ovate, somewhat pointed at the apex, covered with a fine silky slightly golden pile, and sprinkled with long erect pale hairs; the scale of the peduncle forming a blunt rounded node. Hab. Java. This probably belongs to a different genus, or at least to a very distinct section, but, only being acquainted with one sex, I leave it at present in the genus Formica; the palpi are more elongate than is usual, the joints of the antennae are much longer and more slender, the insect having very much the appearance of a species of Dolichoderus.
