Head but little longer than broad, broader behind than in front, with 

 slightly excised posterior border and slightly convex cheeks, convex dorsal and 

 flattened gular surface. Eyes moderately large, feebly convex. Mandibles 6- 

 toothed. Clypeus rather indistinctly carinate, its anterior border produced as 

 a broad lobe, rounded on the sides and sinuately excised in the middle. 

 Frontal cariuse lyrate. Antennal scapes flatten d but not dilated at the base, 

 thickened towards the tips, which reach well beyond the posterior corners of 

 the head. Thorax rather robust, in front narrower than the head, laterally 

 compressed behind ; in profile with evenly arched dorsum. Epinotum rounded, 

 its base fully twice as long as the sloping declivity. Petiole rather high and 

 narrow, with strongly convex anterior, more feebly convex posterior surface 

 and blunt, rounded margin. Gaster of the usual shape. Legs long, middle 

 and hind tibiae distinctly flattened. 



Mandibles shining, striatopunctate near the teeth, but elsewhere with scat- 

 tered punctures. Body, femora and antennae opaque, very minutely and 

 densely punctate, tibije somewhat shining. Clypeus and sides of head with 

 small, scattered punctures. 



Hairs and pubescence yellow, the former moderately abundant but short, 

 present on the postero-lateral portions of the head but not on the cheeks; on 

 the legs short, scattered and oblique, except on the flexor surfaces of the 

 femora, where there is a row of long erect hairs. Middle and hind tibiae with 

 a row of rather short, graduated bristles extending neai'ly their entire length. 

 Scapes without erect hairs. Pubescence short and sparse, distinct only on the 

 dorsum of the gaster. 



Ferruginous red ; mandibles and scapes darker ; anterior border of clypeus 

 and cheeks black. Gaster black, with golden yellow posterior border to eacb 

 segment, a broad transverse golden band on the first, and another at the base 

 of the second segment. 



Worker minor. Length, 7.5-10.5 mm. 



Head longer than broad, slightly broader in front than behind, with rounded 

 postocular portion and feebly convex sides. Clypeus more distinctly carinate 

 than in the worker major, broadly rounded in front, with a very faint median 

 notch. Antennal scapes very slightly flattened at their bases. Thorax similar 

 to that of the worker major, but base of epinotum fully three times as long as 

 the declivity. Petiole longer than broad, but higher than long, thick and sub- 

 conical, with blunt border. 



Sculpture, pilosity and color as in the worker major, but mandibles not 

 darker than the remainder of the head, clypeus somewhat yellowish and 

 antennal scapes red like the funiculi. 



Female. Length. 15-16 mm. 



Pale ferruginous, antennal funiculi, gaster and legs more or less yellowish 

 red, mandibles reddish brown, scutellum, especially near its edges, and the 

 tarsi brown, posterior border of gastric segment and anterior portion of same, 

 excepting the first segment, dark brown. Pilosity as in the worker, but 

 sparser. Head as in the major worker very finely and densely punctate, 

 partly finely shagreened, and in addition, especiall^^ on the clypeus and cheeks, 

 with scattered punctures. Mandibles nearly smooth, \with scattered punctures.
