(PI. II, fig. 17.) 
Worker, — Length, 5.6 mm. 
Chocolate brown ; gaster black ; node blood red ; antennae and legs 
reddish yellow, darker towards apex of scapes, femora, and tibiae. 
Head, thorax and postpetiole densely and finely rugose, node more coarsely 
so, gaster finely and densely punctate. 
Hairs reddish, short and erect, moderately abundant throughout. 
Pubescence very short, fine and adpressed. 
Head one-seventh longer than broad, as broad in front as behind, broadest 
at eyes, sides and occipital border convex. Mandibles triangular, external 
border almost straight, terminal border concave, indistinctly dentate, apex 
long and sharp, angle between the terminal and inner borders rounded. Clypeus 
broadly rounded in front, rising abruptly level with top of frontal carinae, the 
latter flat above, rather broad, hardly continued beyond the lobes, these 
overhanging the antennal insertions. Scapes extend beyond occipital border 
by one and a half times their thickness : first segment of funiculus barely as 
long as second, the others subequal to apical which is as long as the two pre- 
ceding together. Eyes large and convex, their posterior margin at middle of 
head. Thorax barely twice as long as broad. Pronotum one and a half 
times broader than long, suture deeply impressed. Mesonotum and epinotum 
united without traces of a suture ; in profile feebly convex longitudinally, the 
declivity short, rounded into dorsum, sides and top feebly margined. Node 
one-third broader than long, anterior face and sides strongly convex, posterior 
face concave, the superior edge sharply marginate with a sharp tooth-like 
projection in the middle, this tooth being the terminal of an obsolete carina on 
dorsum. In profile higher than long, the anterior face vertical, feebly convex, 
rounded into dorsum, latter feebly convex ; a short sharp tooth behind, at 
posterior fourth, directed backward. Postpetiole one-third broader than long, 
convex in front and on sides. A strong constriction between postpetiole and 
gaster, the latter slightly broader than long, sides strongly convex. Legs 
long and slender.
