Legs neither long and slender nor very robust. Femur lengths 
front to back 1.48, 1.50; 1.45, 1.45; 1.64, 1.65 rnm., not incrassate 
(W/L 18, 18; 17, 18; 16, 16%). Hind tibia length 1.33, 1.48 min. 
Middle and hind tarsi each with one short simple apical spur. Hind 
metatarsus 1.16, 1.29 mm.; tarsal claws simple. 
Most of body with fine dense punctulate striae overlain by a 
coarse broken wavy sculpture (figs. 1-4): clypeus, top, sides and 
back of head, trunk (except those areas listed below), petiolar node 
and postpetiole. In other places the overlying sculpture is much 
reduced or absent, leaving largely flat surfaces of fine, punctulate 
striae: gula (some weakly undulate sculpture present), anterior face 
of pronotum, prosternum, forecoxae, dorsomedial surfaces of meta- 
pleural gland bullae, declivous face of propodeum (striae coarser, 
less dense), most of first gastric segment (striae weaken caudad). 
Striation much reduced, leaving predominately fine, densely punc- 
tate surfaces on: antennae (striae present but finer than elsewhere 
and not predominate), legs except first coxae, and end of first and 
most of succeeding segments of gaster (narrow coriaceous margins 
on each). Mandibles finely longtitudinally striate, without punc- 
tures. Inner surface of mandibles, peduncle and venter of petiole 
smooth and shining; the latter with scattered punctures. Striation 
more or less longitudinal on mandibles, antennae, clypeus, dorsum 
and sides of head, mesonotum, sides of trunk (though much 
confused in parts), coxae, anterior face and sides of petiolar node, 
sides and venter of postpetiole, and gaster. Striation essentially 
transverse on gula (bisected by median longitudinal ridge), pro- 
notum, basal and declivous faces of propodeum (striae converge on 
apices of spines from all sides), dorsal surface of petiolar node, 
anterior and dorsal faces of postpetiole (transversely arcuate). 
Whole body, except peduncle of petiole, covered with short, stiff, 
erect, acute golden hairs, interspersed with shorter, more flexuous 
recurved hairs. Apron of clypeus with longer flexuous hairs; hair on 
mandibles more decumbent. No psainmophore of any sort. Color 
uniformly dark ferruginous brown, except for brown to yellow 
apical antennomere. 
Worker 
(Figs. 6-8) 
The worker is most strikingly different from the queen in its jet 
black color, its larger head, and smaller waist and gaster. It appears
