Head through the eyes somewhat broader than long, semicircularly rounded behind, with short, straight, anteriorly converging cheeks. Eyes and ocelli large and prominent. Clypeus like that of the worker, but with only an indistinct trace of the median denticle. Mandibles narrow, somewhat broadened apically, bidentate, the apical tooth acute, the basal short and blunt. Antennae 10-jointed; scapes fully 5 times as long as broad; first funicular joint nearly twice as long as broad; joints 2-5 small, nearly as long as broad; club very distinctly 4-jointed, the 3 basal joints subequal, longer than broad, together much longer than the somewhat more swollen terminal joint. Thorax large, broader than the head; mesonotum large, subcircular, as broad as long, very convex in front, flattened behind. Epinotum small, lower than the mesonotum, shaped somewhat as in the worker. Petiolar scale lower and thicker, its summit much less acute, from behind straight, transverse and entire. Gaster shaped as in the worker; genitalia large and exserted (Fig. 3). Legs long and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
