in the middle. Frontal area subtriangular, about as long as broad, with rounded 

 sides and a median cannula. Tips of antennal scapes reaching just beyond 

 the eyes. Pronotum subhemispherical, about half as broad as the head, with 

 prominent but rounded humeri and without a distinct promesonotal constric- 

 tion. Mesoepinotal constriction rather deep and broad. Epinotum with two 

 stout spines which are further apart than long, rather blunt at their tips, directed 

 upward and backward and somewhat outward, and each continued anteriorly 

 and posteriorly into a prominent ridge. Epinotal dechvity gradually sloping 

 between the spines. Petiole from above somewhat violin-shaped, nearly twice 

 as long as broad. In profile the node is high, with a rather sharp transverse 

 border, long concave anterior, and short abrupt posterior declivity. Post- 

 petiole twice as broad as the petiole and twice as broad as long, with a blunt 

 conule in the middle on either side. Gaster somewhat smaller than the head. 

 Legs with slightly incrassated fusiform femora. 



Mandibles shining, with coarse, scattered punctures. Clypeus and frontal 

 area shining ; the former irregularly rugulose on the sides. Anterior two thirds 

 of the head sharply longitudinally rugose, posterior third smooth and shining, 

 with a few coarse punctures. Thorax subopaque, punctate-rugose, the rugae 

 on the pro- and mesonotum somewhat concentric on the sides and sometimes 

 leaving a small smooth area in the middle of the dorsum; mesoepinotal con- 

 striction and epinotal declivity shining, the latter with transverse rugae. Peti- 

 ole subopaque, densely punctate; postpetiole smooth and shining, with more 

 opaque, punctate sides. Gaster smooth and shining. 



Body and appendages clothed with sparse, rather long, suberect, yellowish 

 hairs. 



Head dark brown ; mandibles and a broad band across the anterior portion 

 of the head, reddish yellow; apical third of mandibles, petiole, postpetiole, and 

 gaster black; thorax dark brown, mesoepinotal constriction, epinotal declivity, 

 legs, and antennas reddish yellow. 



Worker. — Length 1.5 — 1.75 mm. 



Mandibles multidentate, with the two apical teeth most prominent. Head, 

 excluding the mandibles, a little longer than broad, subquadrate, with slightly 

 convex sides and nearly straight posterior border. Eyes a little in front of the 

 middle of the sides. Clypeus short, convex, with its anterior border excised in 

 the middle. Antennal scapes extending a little beyond the posterior comers 

 of the head. Frontal area very distinct, impressed, rounded behind. Pro- and 

 mesonotum evenly rounded above and on the sides, less convex than in the 

 soldier. Epinotum with the basal and declivous surfaces of equal length, the 

 latter very sloping; spines rather acute, about as long as their distance apart 

 at the base, diverging upward, outward, and backward. Petiole very similar 

 to that of the soldier, but proportionally narrower. Postpetiole a little wider 

 than the petiole, as long as broad, with sides faintly angular in the middle. 



Mandibles, head, postpetiole, gaster, and appendages very smooth and 

 shining. Cheeks and front with a few longitudinal rugas. Mandibles coarsely 

 and sparsely punctate, thorax and petiole opaque, densely and very uniformly 

 punctate. 



Hairs on the body and appendages white, suberect, and rather sparse; 

 tapering except on the thorax and pedicel, where they are somewhat enlarged 

 towards their tips. .
