wheeler: the ants of Borneo. 67 



joints 2-7 of the funiculi distinctly broader than long; club somewhat longer 

 than the remainder of the funiculus. Thorax robust, the pronotum broad 

 and convex, its humeri protruding as bluntly rounded angles; mesonotum 

 sloping, with a transverse torus in the middle. Epinotum low, its base in 

 profile straight and longer than the declivity; the spines short, rather erect, 

 much shorter than the base of the epinotum and shorter than their distance 

 apart at their insertions. Petiole short, the anterior slope of the node very 

 concave, its summit blunt, transverse, and rather deeply emarginate, its 

 posterior slope abrupt. Postpetiole slightly broader than the petiole, trans- 

 verse, very convex above, broader in front than behind, the sides rounded. 

 Gaster broadly elliptical, flattened, smaller than the head, with straight 

 anterior border. Legs with stout, slightly swollen femora. 



Somewhat shining; mandibles smooth, minutely and sparsely punctate. 

 Clypeus smooth and shining in the middle, rugose on the sides; remainder of 

 head sculptured, the anterior f longitudinally rugose, with feebly reticulate 

 interrugal areas, especially on the sides, the posterior third reticulately rugose, 

 the scrobe-like areas densely punctate. Neck, pronotum, and mesonotum 

 more finely reticulate-rugose; epinotum smooth and shining; petiole and 

 postpetiole subopaque, indistinctly and very finely punctate or alutaceous. 

 Gaster and legs smooth and shining, sparsely and finely punctate. 



Hairs yellow, erect or suberect, coarse, rather long, of uneven length, more 

 abundant on the body than on the appendages. 



Ferruginous; gaster darker, brown; legs and antennae paler, more j^ellow- 

 ish; borders of mandibles and clj^peus blackish. 



Worker. Length 1.4 nun. 



Head 3- longer than broad, subrectangular, with very feebly convex sides 

 and feebly sinuate posterior border, as broad in front as behind. Eyes very 

 small, at the middle of the sides of the head. Mandibles with oblique apical 

 margins furnished with four acute, subequal teeth. Clypeus short, convex, 

 its anterior border broadly rounded, entire. Antennal scapes reaching the 

 posterior border of the head. Thorax rather slender; pro- and mesonotum 

 fused, feebly rounded above and on the sides; mesoepinotal constriction short 

 and deep. Epinotum with subeqvial base and declivity, the spines reduced 

 to small, rather blunt teeth, not longer than broad at their bases. Superior 

 border of petiolar node transverse and entire. Postpetiole much as in the 

 soldier. 



Smooth and shining; mesopleurae and sides of epinotum densely punctate; 

 petiolar and postpetiolar nodes subopaque. 



Hairs whitish, erect, more uniform and somewhat more abundant than in 

 the soldier, especially on the legs and scapes. 



Yellowish brown; head and gaster a little darker; thorax and appendages 

 paler and more yellowish.
