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.
