projection. Postpetiolc a little narrower than the petiole, transversely 

 elliptical, twice as broad as long and more than half as broad as the 

 first gastric segment, ventrally with two blunt transverse projections. 

 Gaster short, one and two-thirds as long as broad, first segment some- 

 what shorter than broad. Legs very short, flattened; femora very 

 broad, elliptical, tips of middle and hind tibiae and metatarsi dentate 

 as in the other species. 



Shining; mandibles striato-punctate, basally smoother and sparsely 

 punctate. Ch'peus, head and thorax regularly and rather finely 

 longitudinally striate; the posterior fourth of the head smooth and very 

 shining. Interspersed with the striae on the head are a few coarse 

 punctures, arranged in rows, but becoming sparse on the occiput. 

 The striae on the pro- and mesonotimi are somewhat finer and more 

 regular than those on the head, on the base of the epinotum they are 

 still finer and merge posteriorly into lines of punctures diverging to 

 the posterior comers and into scattered punctures on the declivity. 

 Sides of thorax obliquely striate. Petiole, post-petiole and gaster 

 punctate, the gaster more finely. Legs smooth and shining, with very 

 fine, sparse punctures. 



Hairs yellow, in the form of sparse pubescence on the head and 

 thorax, becoming conspicuously longer, more abundant and suberect 

 on the gaster and especially on the sides of the petiole and postpetiole. 

 There are also a few short erect hairs on the head and thorax. Legs 

 with very short, rather bristly hairs, oblique on the tibi«. 



Rich castaneous brown; mandibular teeth and lateral borders of 

 clypeus and anterior border of head black; antennas a little paler brown; 

 gaster and legs ferrugineous. 



Described from 10 workers taken at Dorrigo, New South 

 Wales (Museum of South Australia). 



This species, which I dedicate to my friend, the eminent 

 Australian entomologist, Dr. R. J. Tillyard, resembles hakeri 

 most closely in the structure of the head and clypeus, but in 

 color and sculpture it is more like greeni and mjobergi, though 

 sufficiently distinct from either.

(Fig. 7.) 



Male. Length 6-7 mm. 



Body long and slender. Head as broad as long, evenly convex and 

 rounded behind, without posterior corners; cheeks very short; eyes 

 moderately large, but not very convex; ocelli rather small. Mandibles 

 small, but well developed, their external borders slightly sinuate basally, 

 convex at the tips, apical and basal borders distinct, subequal, the 

 former with four subequal teeth. Clypeus large, convex, somewhat 

 broader than long, slightly depressed or flattened posteriorly. Front
