that the clypeus does not seem to stand away from the mandibles. 

 Thorax very feebly convex, two and one-fourth times as long as broad, 

 ^with parallel sides. Anterior eomers of pronotum obtuse; posterior 

 comers of the concavely emarginate epinotum protruding and swollen, 

 a condition not seen in grecni. Promesonotal suture absent, mesoepinotal 

 suture feebly ihdicated (deeply impressed in greeni). Petiole much 

 broader and shorter than in greeni, as broad as the epinotum, not quite 

 twice as broad as long, its anterior border feebly, its posterior border 

 deeply concave, narrower in front than behind, where its angles extend 

 out as flat, lobular projections. It is truncated anteriorly and posteriorly 

 and even somewhat concave in front, and bears ventrally only one 

 strong longitudinal lobe. Postpetiole not broader than the posterior 

 border of the petiole, scarcely one and one-half times broader than long, 

 rounded on all sides, only about half as broad as the gaster, with two 

 teeth below. Legs of the same shape and quite as broad as in greeni, 

 the tibiae shorter and stouter than in sauteri. 



Sculpture of body, especially of the head, somewhat weaker and 

 more finely longitudinally striate than in greeni; petiole and gaster 

 distinctly more densely punctate. Mandibles nearly smooth, feebly 

 striate and sparsely punctate. 



The gaster and thorax exhibit a very short, fine, rather abundant, 

 erect pilosity, which partly passes over into the pubescence and is 

 sparser on the posterior portion of the head. There are only a few long 

 hairs. 



Pale brown, head dark brown; appendages brownish yellow. 



Female (dealated). Length 7.9 mm. 



Scarcely distinguishable from the worker, only much darker, brown- 

 ish black, and with more distinct sutures outlining the mesonotum and 

 scutellum. Hind corners of epinotum less protuberant, eyes large, 

 ocelli present. Postpetiole somewhat broader than in the worker. 



Type-locality: Malanda, Queensland (E. Mjoberg).

 Forel, Arch. f. Naturg. 79, 1913, p. 1S9, Fig. 9 . 



Female. Length 10.5-11.1 mm. 



Head rectangular, at least one and one-half times as long as broad, 

 with straight sides and feebly concave posterior border. Eyes much as 

 in greeni. Mandibles much longer and broader, with straight 5-6-toothed 

 terminal border and longer and broader basal lobe. Clypeus with 

 more distinct posterior suture, its anterior rectangular lobe much longer 

 than in greeni, with perfectly straight anterior border, concave sides and 

 acute corners. Frontal groove distinct. Antennae very similar to 

 those of greeni, but somewhat longer and narrower, especially the scape. 

 Thorax decidedly narrow^er than the head, but otherwise as in greeni, the 

 epinotum, however, much longer, nearly one and one-half times as long 

 as broad, more strongly convex and less strongly marginate on the 

 sides. Petiole also longer, mt:ch longer than broad, posteriorly with
