MANN: ANTS OF THE BRITISH SOLOMON ISLANDS. 325 



scapes extending about two thirds the distance to occipital corners; first 

 funicular joint as long as the three succeeding joints together; joints two to 

 seven strongly transverse; club large, longer than the rest of funiculus. Eyes 

 little convex, situated at sides of head well in front of middle. Promesonotum 

 flattened; humeri bluntly annulate. Mesoepinotal suture moderately im- 

 pressed. Basal portion of epinotum flat, longer than the declivity; declivity 

 flat, with blunt, elevated margins laterally. Petiolar node a little longer than 

 broad; in profile slightlj' longer than high, with sloping anterior and rounded 

 posterior surfaces. Postpetiole subglobose, a little broader than petiole. 



Feebly shining throughout. Mandibles sparsely punctate. Head reticu- 

 lately striate and punctate; clypeus smooth. Promesonotum and epinotum 

 striolate and punctate, more finelj' and shallowly than the head, with the base 

 of epinotum as strongly so as the rest; thoracic pleurae cribrately punctate; 

 petiole and postpetiole densety but more shallowly punctate. Gaster with 

 fine piligerous punctures. 



Fine, long, erect yellowish hairs moderately abundant on head and body; 

 shorter and semirecumbent on appendages. 



Dark brown to black; antennae and legs yellowish brown; femora infuscated 

 at basal two thirds. 



Malaita: Auki. 



Near hrevicornis Emery but with the scapes a little longer and the 

 sculpture entirely different. The small size, more elongate head and 

 the sculpture of the basal portion of the epinotum distinguish it 

 from subtilis Emerv and its varieties.

 transverse; club large. Eyes slightly convex, situated at sides of head a little 

 in front of middle. Promesonotum flattened; humeri obtusely angulate.
