constricted behind, with a bhmt, transverse anteroventral pro- 

 jection. Gaster rather larger, somewhat longer than the thorax. 

 Legs not incrassated. 



Shining, especially the mandibles, clypeiis and gaster. Mandi- 

 bles sparsely punctate, clypeus smooth, indistinctly rugulose on 

 the sides. Head longitudinally rugose, the rugte becoming coarsely 

 reticulate on the occipital region. Scrobes and interrugal spaces 

 indistinctly punctate-reticulate. Region of the frontal groove 

 occupied by a smooth shining longitudinal streak. Thorax, 

 petiole and postpetiole irregularly, their upper surfaces more 

 transversely rugose. Declivity of epinotum smooth and shining. 

 Gaster with sparse, piligerous punctures. 



Hairs moderately long and abundant, erect or suberect, yellow- 

 ish, bristly, covering all parts of the body, shorter and sparser on 

 the legs and scapes, rather dense on the funiculi. 



Dark piceous brown; thorax, petiole and postpetiole nearly 

 black; mandibles, clypeus, cheeks, base and tip of gaster, legs, 

 including the coxae, first joint of funiculi and their clubs reddish 

 brown. 



Male. Length 3 mm. 



Head as broad as long, broadly rounded behind, without pos- 

 terior angles, somewhat flattened above, with very short cheeks. 

 Clypeus much as in the worker. Pronotum visible from above, 

 not overarched by the mesonotum which is as broad as long. 

 Scutellum not very prominent. Epinotum sloping, simple, un- 

 armed. Petiole fully twice as long as high and more than twice 

 as long as broad, parallel-sided. Postpetiole from above broader, 

 nearly square. 



Head and thorax subopaque, rather finely and irregularly punc- 

 tate-rugulose; mesopleurre, a longitudinal streak on the front of 

 the head, the petiole, postpetiole and gaster smooth and shining, 

 the gaster with fine sparse piligerous punctures. 



Hairs finer and more oblique than in the worker, very numerous 

 on the antennae and wings, which are unusually pubescent. 



Dark piceous brown, nearly black; legs and antennae paler; 

 clypeus and mandibles yellowish. Wings opaque brownish, with 

 brown veins and pterostigma. 



Described from numerous workers and five males collected by 

 Mr. A. M. Lea on Lord Howe Island.
