terminal joint thick, as long as the two preceding joints. Eyes composed of 

 4-5 facets, situated at anterior fourth of sides of head. Thorax elongate, 

 slightly convex above, promesonotal impression distinct, mesoepinotal im- 

 pression obsolete. Pronotum a little broader than long. Epinotal declivity 

 flat, obtusely margined at sides, the margin with a broadly rounded angle at 

 middle. Petiolar node in profile with nearly straight anterior and posterior 

 surfaces, rounded above, the top about one half as long d,s the base; from above, 

 much broader than long and rounded at sides. 



Head and thorax opaque. 



Feebly shining. Mandibles, gaster, and appendages shining. Mandibles 

 with distinct, separated punctures. Head, thorax, and epinotum densely 

 cribrately punctate, petiole and gaster more shallowly punctate. 



Pruinose pubescence rather abundant, fine scattered erect hairs sparsely 

 distributed on head, body, and appendages. 



Dark reddish brown to black. Legs lighter. 



Viti Levu: Nadarivatu. 



Near P. perkinsi Forel from Hawaii, but larger, more robust and 

 more coarsely sculptured. There is a faint depression at the meso- 

 epinotal suture, which does not, however, break the sculpture and is 

 not as distinct as in perkinsi. The occiput is distinctly concave. 

 Because of these characters it is related to biroi Emery, a New Guinea 

 form, from which it differs in having the head more strongly 

 cribrately punctate and the joints of the funiculus only slightly 

 broader than long. Type— M. C. Z. 8,687. 



9. PONERA TURAGA,^ Sp. nOV. 



Worker. Length 3.25-3.75 mm. 



Head distinctly longer than broad, occipital border rather strongly and 

 narrowly concave. Mandibles elongate, their blades with 8-9 irregular teeth. 

 Clypeus projecting and rounded at middle of anterior border. Antennal 

 scapes extending six sevenths the distance to occipital corners; first funicular 

 joint longer than the second and third together, joints 2-7 as long or slightly 

 longer than broad, the remaining joints, except the terminal, a little broader 

 than long, terminal joint thick and shorter than the two preceding joints 

 together. Eyes composed of eight ommatidia, situated at anterior fifth of 

 sides of head. Thorax robust, promesonotal suture strong, mesoepinotal 

 impression barely discernible. Declivous portion of epinotum flat, roundly 

 margined at sides. Petiolar node from above two and one half times as broad 

 as long, straight in front and behind and rounded at sides; in profile thick,
