Worker. (Plate 1, fig. 11). Length 8 mm. 
Head, excluding mandibles a little longer than broad; broadest at 
eyes; occipital border deeply excised; sides above eyes concaye, 
below sinuate, with the lower surface flattened. Eyes large, and con- 
vex. Clypeus between frontal lobes triangular, the surface flat, 
anterior portion bilobed; border concave at middle. Frontal carinae 
short. Mandibles about two thirds as long as head, narrow at base, 
broad and flat anteriorly, the blade edentate to near apex, where 
there is a short, thick tooth; apex with two long teeth, between which 
is a smaller, acute tooth. Antennae slender, the scape curved, 
thickened at middle, extending one eighth its length beyond the 
occipital corners; funicular joints long and slender, 1 to 10 subequal, 
apical joint nearly twice the length of subapical. Prothorax much 
narrowed in front, rounded above and at sides, the posterior border 
slightly concave. Promesothoracic suture deeply impressed; meso- 
thorax transverse, rounded above and at sides. Mesoépinotal im- 
pression deep and broad; epinotum much narrower than prothorax, 
straight at sides and above to the declivity, which is very short, and 
concave; angle with a pair of short, acute, erect spines. Node 
triangular, the apex with a pair of strong spines, between these 
broadly concave. Gaster short and thick, the first segment with 
a small ventral tooth. Sting long and powerful. Legs long and 
slender. 
Head in front subshining, with dense striolae, which extend upward 
and outward from the frontal area; the remainder of head and 
the mandibles smooth and very shining. Antennae sublucid, finely 
pubescent. Thorax shining, rugosely punctate; the mesothoracic 
pleurae smooth. Node shining, transversely rugose in front, smooth 
behind. Legs and gaster shining, finely punctate.
