Worker. — Length, 5-7 mm. 



Head about one and one-quarter times as long as broad, 

 as broad in front as behind, with feebly convex sides, rounded 

 posterior corners and a pronounced, reflected occipital margin. 

 Eyes rather small, convex at the middle cf the sides of the 

 head. Mandibles long, with rather straight external borders, 

 their apical borders irregularly denticulate, with three larger 

 teeth at the tip. Clypeus moderately convex, its anterior 

 border broadly rounded and entire. Frontal carinae sub- 

 parallel; frontal area large, triangular; frontal groove indis- 

 tinct. Antennae slender; scapes extending about one-fourth 

 their length beyond the occipital border of the head, their 

 tips distinctly incrassated ; funiculi with distinct 4-jointed 

 club, and all the joints more than twice as long as broad. 

 T borax rather long and slender, pronotum slightly flattened 

 above, rising posteriorly to the mesonotum, which slopes 

 rapidly backward and is slightly concave anteriorly in profile, 

 marginate on each side above and along its inferior border. 

 Mescepinotal constriction abrupt and rather deep. Epinotum 

 as high as long, its base horizontal and straight, forming a 

 right-angle with the shorter declivity; the spines somewhat 

 curved at base, slender and acute, less than half as long as 

 the declivity, nearly as long as their distance apart at the 

 base and directed backward and slightly outward. Petiole 

 with a slender peduncle shorter than the node, which is rather 

 high and rounded above, its anterior slope rising abruptly 

 and perpendicularly from the peduncle. Seen from above, 

 the node is longer than broad. Postpetiole a little higher 

 than the petiolar node and somewhat broader. Legs long and 

 slender; spurs of the hind tibiae very small. 



Shining; mandibles subopaque, coarsely striated; clypeus 

 and head above smooth and shining, longitudinally rugose
