thickened towards their tips, which extend a httle beyond the posterior orbits; 

 fiinicuU rather long, joints 1-9 broader than long, joint 10 as long as broad, 

 terminal joint as long as the two preceding joints together, somewhat tapering 

 and not broader than the penultimate joint. Thorax shghtly narrower than 

 the head, distinctly broader through the epinotum than through the pronotimi, 

 less than twice as long as broad, without promesonotal and mesoepinotal 

 sutures. Pro- and mesonotum together rectangular, as long as broad; epino- 

 tum with rounded, rather swollen sides. In profile the whole thorax is feebly 

 and evenly rounded above. Epinotal declivity abrupt, very strongly carmate 

 above and on the sides, as is also the pronotum. Pleurae concave. Petiole 

 as broad as the epinotimi, rectangular, nearly I5 times as broad as long, as 

 broad in front as behind, feebly convex above, truncated anteriorly and 

 posteriorly, with its anterior and lateral borders marginate and its posterior 

 angles produced as a pair of triangular, rather acute teeth. Postpetiole 

 rectangular, a little broader than long, as broad in front as behind and as 

 broad as the petiole, feebly convex above, marginate in front, with sharp 

 anterior corners, submarginate on the sides. First gastric segment a httle 

 larger than the postpetiole, as long as broad, with more convex sides and 

 dorsum, ventrally, in front, with a conspicuous rounded tubercle. Pygidium 

 truncate, with finely spinulate border. Legs rather short, hind coxae with a 

 rounded expansion at the tip on the inner side. 



Moderately shining; mandibles very sparsely and coarsely punctate; body 

 finely punctate, dorsal surfaces of head and thorax also with irregular scattered 

 foveolae; region between the eyes and frontal carinae smooth and shining. 

 Sides of head and thorax also more shining and less punctate. 



Hairs and pubescence grayish, the hairs rather short, sparse, erect, both on 

 the body and appendages, longest and most abundant at the tip of the gaster, 

 the pubescence rather long and abundant, especially on the petiole, postpetiole, 

 gaster, legs, and antennae, but also well-developed on the thoracic dorsum and 

 head. 



Black; mandibles, antennae, legs, pygidium, and sting dark red, the middle 

 portions of the scapes, femora, and tibiae somewhat darker. 



Female. Length 4 mm. 



Very similar to the worker. Thorax through the wing-insertions- as broad 

 as the head; mesonotum small, flat, a httle broader than long, shaped like an 

 isosceles triangle, with the apex directed anteriorly. Sculpture, pilosity, and 

 color as in the worker. Wings yellowish hyaline, with pale yellow veins and 

 conspicuous brown pterostigma. 



Described from four workers and three females taken by Mr. John 

 Hewitt at Kuching. Type.— M. C. Z. 8,945. 



This species seems to be closely related to Ph. pubescens Emery, 

 described from a dealated female, but hewitti is much smaller {pubes-
