Head as long as the greatest breadth, narrowed both in front of and behind the eyes ; opaque, very finely and shallowly reticulate, with sparse piliferous punctures. Eyes separated across the frons by twice the diameter of either and situated nearer to the base of the mandibles than to the posterior margin of the head ; ovate and smooth ; ocelli in an equilateral triangle, the posterior pair a little farther from each other than from the hind margin of the head. Antennae thirteen-jointed, as long as the thorax and propodeon together. Scape about twice the pedicel, the latter slightly exceeding the first funicular joint ; joints of the funicle subequal, no definite club ; the last joint and the fourth and fifth of the funicle longer, equalling the pedicel.
