tion of basal and declivious faces. Petiole with a well-marked 
peduncle bearing a long, low, mid-ventral keel terminating in a 
small tooth; anterior surface of node rather steep and flat, 
posterior surface convex; summit of node truncated and with 
a broad, shallow emargination across its whole width, the lateral 
angles rounded. Postpetiole globose, and ^3 wider than the 
petiole, its dorsal border flat and entire. Abdomen egg-shaped 
as usual in ant queens. Legs slender. Wings hyaline and with 
veins much reduced; costal, median and radial cells present, one 
closed discoidal cell weakly indicated. 
Sculpture: Front and sides of head with fine, longitudinal 
rugae, and clypeus longitudinally striated except in the median 
area; vertex and gula non-striated; all surfaces of the head 
except the front and clypeus pitted with abundant, deep punc- 
tures; mandibles striato-punctate. Thorax, including the epi- 
notum, with numerous though more scattered punctures, and 
its surface very shining; a few striations appear on the post- 
scutellum and on the pleurae just below the wing insertions; 
metanotum with rather coarse, transverse rugae, and the epi- 
notum has coarse, parallel rugae on all surfaces, trending antero- 
posteriorly on the sides and transversely across the base and the 
declivity. Petiole and postpetiole, except the dorsal surfaces, 
with distinct rugulations. Abdomen smooth and shining, but 
having deep, piligerous punctures. 
Pilosity: Head, thorax, petiole, postpetiole, and abdomen 
covered with abundant, long, light yellow, flexuous hairs, except 
the mid-dorsal areas from anterior to posterior in each of these 
regions; legs, scapes, and antennal funiculi equally pilose. 
Pubescence on all parts absent or at most extremely dilute. 
Color: Yellowish brown to brown on the head, thorax, legs, 
scapes, funiculi, and sides of petiole and postpetiole; mandibles, 
tibiae, and tarsi lighter; postero-dorsal portion of head, the 
mesonotum, petiole, and postpetiole darker and in some speci- 
mens almost black; entire gaster, except the posterior tip, of a 
deep, bluish black, metallic luster.
