petiolar node and the peduncle with long silky, flexuous hairs, which are 

 semirecumbent on posterior portions of gaster and erect elsewhere. Antennae 

 and legs with shorter hairs. 



Color ferruginous; legs, antennae, and mandibles testaceous. Pilosity 

 ' white. 



Female. Length 2.25 mm. 



OcelU small. Similar to worker. The petiolar node is thicker and the 

 epinotal spines stronger. Wings hyaline. Veins and stigma brown. 



Ysabel: Fulakora (Type-locality). Ugi: Pawa. San Cristoval: 

 Star Harbor. Malaita: Auki. 



Described from a few specimens found in very small colonies beneath 

 stones. The concave and impunctate epinotum, the stronger spines, 

 the irregular punctation of the pro- and mesothorax, the smaller size 

 and different coloration distinguish it from the preceding species.

71. Tetramorium salomo, sp. nov. 



Worker. Length 2.50 mm. 



Head a little broader than long, sides in front of eyes somewhat convergent, 

 occipital border shallowly concave. Mandibles 6 -dentate, the two anterior 

 teeth larger than the others. Clypeus subcarinate at middle, straight at ante- 

 rior border. Frontal ca/inae delicate though distinct, scrobes poorly defined. 

 Antennal scapes shghtly surpassing occipital corners; funicular joints three to 

 seven distinctly transverse, the others as long or longer than broad. Thorax 

 evenly convex in profile, not impressed, humeri narrowly rounded. Epinotal 

 spines very slender and acute, a little longer than their distance apart at tips, 

 nearly straight, extending backward and slightly upward. Inferior epinotal 

 angles produced as flat, triangular spines, rather obtuse at tips and a little more 

 than one third as long as dorsal spines. Petiolar node from above oval, nar- 

 rowed in front, from the side longer than broad evenly convex above, in front 

 evenly rounding into the slender peduncle; anteroventral spine elongate, 

 rounded at tip. Postpetiole broader than petiole and a little broader than 

 long. Legs rather slende.'. 



Gaster very shining, legs moderately shining, the rest subopaque. Man- 

 dibles finely punctate, anterior border with short striae. Clypeus with uneven 

 surface and fine longitudinal striae. Head with a series of serrated, slightly 

 tortuous striae which have a tendency to become reticulate on occiput, the 

 interspaces foveolately punctate and rugulose. Thorax and petiole coarsely
