MANN: ANTS OF THE FIJI ISLANDS. 445 



of a broad stout triangular tooth; blades 4-dentate, third tooth distinctly 

 smaller than the others. Clypeus flat at middle, not carinate, margined 

 laterally, anterior border with three triangular teeth and concave between 

 them. Frontal area distinct, suboval, impressed. Frontal carinae fine, 

 extending about two thirds the length of scapes. Scapes ahnost attaining 

 occipital corners; first and second funicular joints longer than broad, joints 

 3-7 transverse, subequal; terminal joint longer than the two preceding joints 

 together. Eyes convex, situated at sides of head slightly in front of middle. 

 Thorax robust, flat above. Pro- and mesonotum with a strong short lateral 

 constriction between, at the sides narrowly rounded and gibbous in appearance. 

 Base of epinotum a little broader than long, subgibbous basally at sides, con- 

 cave between the spines which are rather stout, as long as their distance apart 

 at base, directed upward and backward, with a slight curve forward and 

 moderately divergent; declivity nearly as long as base. Peduncle of petiole 

 about as long as node; node higher than long, with concave anterior face 

 narrowly rounding into dorsal surface; highest at anterior end, with dorsal 

 and posterior surfaces broadh' rounding into each other. Postpetiole two 

 times as high as long, rounded ddrsally; from above subquadrate, very slightly 

 broader behind than in front and a little broader than long. 



Shining. Mandibles finely punctate. Front and sides of head and the 

 occiput with a few large and rather shallow punctures, the rest smooth. 



Long and fine erect hairs very sparse on head, thorax, and abdomen; shorter 

 and more abundant on appendages. 



Bro'ttTiish red to dark reddish brown. 



Viti Levu: Xadarivatu (Type-locality), Waiyanitu, Nasoqo. 

 Taviuni: Somo Somo. Ovalau. 



Nests beneath stones in small colonies. This is a characteristic 

 species, distinct in the large strong tooth at middle of basal border of 

 mandibles, the strongly dentate blade, the trilobed clypeus, with 

 the median lobe triangular and nearly as large as those laterally. 

 The surface of the thorax is uneven and might be described as broadly 

 WTinkled, and the sculpture unusually fine and sparse. Type. — ■

PoECiLOMYRMA, geii. nov. 



Near Podomyrma F. Smith. 



Medium sized species, with moderately well-differentiated worker major 

 and worker minor castes. Head of moderate size. Mandibles with broad, 

 dentate blades. Clypeus moderately enlarged at middle, narrowed in front of 

 antennal sockets, but not reduced to a mere ridge as in the Tetramorii. An- 

 tennal fossae broad, subcircular, not very deep. Frontal carinae feebly
