246 WHEELER. 



front as behind, very feebly narrowed in the mesonotal region. An- 

 terior border, sides and boundary between base and deeUvity of 

 epinotum sharply marginate, as are also the prosterna and the sides 

 of the epinotal declivity. In profile the thoracic dorsum is feebly 

 and CAcnly convex, the declivity abrupt and nearly straight, the 

 mesopleurfe slightly concave. Petiole a little narrower than the 

 epinotum, rectangular, broader than long, not broader behind than 

 in front, its anterior border broadly excised, submarginate, the sides 

 rather straight, strongly marginate and terminating behind in a pair 

 of flat, pointed teeth. In profile the dorsal surface is feebly convex, 

 as are also the truncated anterior and posterior surfaces; lower sur- 

 face in front with a small, acute backwardly directed tooth. Post- 

 petiole rectangular, a little broader than the petiole and slightly 

 broader than long, the anterior border and anterior corners scarcely 

 submarginate. First gastric segment decidedly broader than the 

 postpetiole, broader than long, with broadly concave anterior border 

 and convex sides. Pygidium broadly concave above, marginate and 

 very finely spinulate on the sides. Legs rather long, hind coxse with 

 a large, rounded, translucent lamella at the tip on the inner side. 



Shining; finely but distinctly shagreened, the head, thorax, petiole 

 and postpetiole more sharply so that these parts are a little less shining 

 than the gaster. Mandibles sparsely punctate, the occiput, dorsum 

 of thorax and abdomen with sparse, shallow, piligerous foveolse. 



Hairs yellow, suberect, delicate, moderately long and abundant 

 on the upper surface of the thorax and abdomen, sparser on the heatl, 

 xery sparse on the legs and scapes. Pubescence long and conspicu- 

 ous on the legs, especially on the tibiije and on the ventral surface of 

 the petiole. 



Uniformly red, of the tint of PoJyergus rufcscens, apical borders of 

 mandibles and carinse of head, thorax and petiole of a deeper color, 

 almost blackish. 



Described from 19 specimens taken Oct. IS, 1914 at Cairns, Queens- 

 land, foraging on a sandy spot in the forest. 



This species resembles Ph. scrutator but dift'ers in being slightly 

 larger, with more robust thorax and in having the head, thorax, 

 petiole and postpetiole shining, the pilosity more delicate and the 

 pubescence much longer and more abundant on the legs.
