margin. Mandibles slender and pointed, with two large apical teeth and a 

 series of 5-6 smaller teeth. Cl3rpeus strongly convex basally, broadly rounded 

 at anterior border. Antennae very slender, their scapes surpassing occipital 

 corners by three eighths of their length; first funicular joint nearly as long as 

 the three following joints together; joints 2-8 about twice as long as broad; 

 club slender, the terminal joint shorter than the other two together. Eyes situ- 

 ated a little in front of middle of sides of head. Thorax elongate, little convex 

 above. Mesonotum margined at sides and produced behind as a rather thick 

 plate, concave above arid excised at middle of tip. Epinotum with a pair of 

 erect spines, longer than the base, bifurcate at tip, similar to those of rooserelti. 

 Petiole elongate, the node in profile bluntly conical; from above, broader than 

 long, with the dorsal border feebly concave. Post-petiole broader than petiole 

 and a little broader than long; in profile about as long as high, evenly rounded 

 above. Legs long, femora moderately enlarged. 



Shining. Mandibles coarsely, sparsely punctate. Cheeks longitudinally 

 striate; remainder of head and body with very sparse, broad, and shallow 

 punctures. 



Fine, long, erect hairs moderately abundant on head, body, and appendages. 



Color as in soldier. 



Viti Levu: Nadarivatu. 



Described from three soldiers and several workers from a small 

 colony found beneath a stone. It is evidently much rarer than the 

 preceding species, to which it is related, but readily distinguished, 

 in the soldier phase, by the characters noted in the key to the species. 



The worker of colaensis has the head shorter and very narrowly 

 concave behind, with the margin rounded. The occiput is sparsely 

 punctate, the thorax is not striate and the lamellate process of the 

 mesonotum is thicker and not strongly impressed before the tip.

1. Mesonotum produced behind as a short lamellate plate. Epinotal 

 spines long and erect, obliquely truncate or bifurcate at tips 2 



Mesonotum of ordinary form. Epinotal spines not truncate or bifurcate at 

 tips ; 3 



2. Mandibular blades concave, bidentate apically. Ch^peus not carinate. 

 Lamellate projection of mesothorax thin and strongly excised apically. Poste- 

 rior portion of head rugose and reticulately striate. Ocelli absent.
