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. Promcsonotum 

 flattened; humeri bluntly angulate. Mesoepinotal suture moderately im- 

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

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

 broad; in profile slightly 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 finely and shallowly than the head, with the base 

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

 petiole and postpetiole densely 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 inf uscated 

 at basal two thirds. 



Malaita: Auki. 



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

 sculpture entirely different. The small size, more elongate head a;nd 

 the sculpture of the basal portion of the epinotum distinguish it 

 from subtilis Emery and its varieties.

Worker. Length 1.75-2 mm. 



Head about a fourth longer than broad, sides subparallel, occipital corners 

 broadly rounded, border shallowly concave at middle. Mandibles 5-dentate. 

 Clypeus convex, rounded above and at anterior border. Antennal scapes 

 extending three fourths the distance to occipital corners; first funicular joint 

 as long as the three following joints together; joints two to seven moderately 

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

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

 Mesoepinotal suture moderately impressed. Basal and declivous surface of 

 epinotum rounding into each other; sides of declivity with margin that is 

 elevated at middle into a small, stout, triangular tooth. Petiolar node a 

 little longer than broad ; in profile about as high as long, anterior face declivous, 

 dorsal and posterior surfaces moderately rounded; antero ventral tooth broad
