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

 smaller than the others. Clypeus Bal at middle, nol carinate, margined 

 laterally, anterior border with three triangular teeth and concave between 

 them. Frontal area distinct, Buboval, impressed. Frontal carinae one, 

 extending about two thirds the Length of scapes. Scapes almost attaining 

 occipital corners) first :m<l second funicular joints Longer than broad, joints 

 8-7 transverse, subequal; terminal joint longer than the two preceding joints 

 together. Eyes convex, Bituated at sides of head Blightly in front of middle. 

 Thorax robust, Bat above. Pro- and mesonotum with a strong short Intend 

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

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

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



at base, directed upward and backward, with a Blight eurve 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 broadly rounding into each other. Postpetiole two 

 t imes as high as long, rounded dorsally; from above subquadrate, v< ry 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 tine erect hairs very sparse on head, thorax, and abdomen; shorter

 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 

 wrinkled, and the sculpture unusually fine and sparse. Type. —
