Paranomopone gen. nov.

Worker. Rather small, monomorphic. Mandibles triangular, with toothed apical borders. Clypeus short, not produced in the middle, indistinctly marked off from the remainder of the head. This is also true of the triangular frontal area. Frontal carinae distinctly dilated, further apart than the distance of each to the lateral border of the head, concealing the insertions of the antennae, continued back about three-fourths the length of the head as the medial border of a deep scrobe which lies entirely dorsal to the eye. The ventral border of this scrobe, which is somewhat more than three times as long as broad, is also very sharp. Its depression is divided by a median longitudinal ridge which does not extend to the posterior end of the scrobe, so that the latter is incompletely separated into two compartments, one for the accommodation of the scape and one for the funiculus, when the antenna is folded back against the head. Eyes small, situated behind the middle of the head. Ocelli absent. Antennae 12-jointed, funiculus somewhat enlarged at the tip into a 3-jointed club, which, however, is not very sharply marked off from the more basal joints. Palpi extremely short. The number of their joints could not be ascertained. Thorax small and short, with a very distinct promesonotal but no mesoe'pinotal suture; epinotum unarmed. Petiole nodiform, attached to the postpetiole by a very small, narrow surface. Postpetiole voluminous, larger than the first gastric segment, constricted behind, remaining gastric segments very small, almost completely telescoped into the first segment. Sting well-developed. Legs rather stout and short; hind tibiœ each with a single large, richly pectinated spur; tarsal claws simple, slender and straight. Sculpture and pilosity rather coarse.

Female. Ergatoid and differing from the worker only in having an anterior ocellus and in the larger size of the postpetiole and first gastric segment, and in the latter being as large as the former.
