with a few very sparse punctures. Head densely and cribrately punctate, 

 thorax and petiole more shallowly and gaster more coarsely punctate than the 

 head. 



Erect hairs short and very sparse on head, body, and antennae; fine, short, 

 silky, yellow pubescence abundant. 



Reddish brown, legs and apical third of antennal funiculus brown-yellow. 



Viti Levu : Waiyanitu. 



Described from a unique worker. Near P. selcnophora Emery 

 from New Guinea, from which it differs in the longer head with less 

 arcuate sides, and in the singularly coarse sculpture of the gaster. 

 The regular, separated punctation of the thorax is peculiar, resem-

others blunt. Cl^-peus strongly coiivex at middle, rounded at anterior border. 

 Antennae slender, their scapes attaining occipital border; first funicular joint 

 as long as the second and third joints together, joint 2 a little longer than 

 broad, 3-10 scarcely broader than long, terminal joint distinctly longer than 

 the two preceding together. Eyes small, of 4-5 ommatidia, situated at 

 anterior fourth of sides of head. Thorax elongate, nearly flat above, pro- 

 mesonotal and mesoepinotal sutures distinct, but not profound. Mesonotum 

 nearly circular, a little broader than long and half as long as pronotum. Base 

 of epinotum twice as long as broad and as long as the declivitj-, which is flat 

 and margined at sides. Petiole distinctly broader than epinotum, the dorsal 

 surface from above twice as broad as long; in profile more than twice as high
