Zool. jahr., 1914, 37, p. 608, S . Worker. Length mm. Head one and three fourth times longer than broad, as broad in front as behind; sides subparallel; occipital angles narrowly rounded, the border feebly concave. Clypeus very broadly and prominently carinate, the anterior border angulate at middle. Mandibles long and slender, with eleven stout teeth. Frontal carinae very short; their lobes little dilated and flat; the narrow frontal depression extending less than half the distance to occipital border. Antennae long and slender; scapes surpassing occipital corners by a distance equal to twice their breadth at apex; first and second funicular joints subequal, three times longer thfin broad; third joint shorter than second and proportionally broader, joints 4-10 longer than broad, subequal in length but increasing in thickness toward apex; terminal joint barely as long as the two preceding joints together. Eyes small, very flat, situated in front of sides of head at a distance of three times their diameter from base of mandibles. Pro- thorax convex, a little broader than long, narrowly rounded at front and sides;. Fig. 8.— Euponera (Mesoponera^ papuana Viehmeyer. Worker. Lateral view of thorax and petiole. anteroventral corners broadly rounded. Premesonotal suture strongly, but less profoundly impressed than the mesoepinotal. Epinotum in profile as long as prothorax, depressed at middle, with a narrow, transverse impression slightly posterior to spiracles; angle between base and declivity broadly rounded and strongly longitudinally impressed at middle, the sides standing out as rounded margins; declivity flat. Petiole squamiform, twice as high as long, narrowly rounded above; anteiior surface convex, posterior flat; sub- marginate above and at sides of posterior border. Gaster long and slender.
