NEW AUSTRALIAN ANTS. 
short and broad, strongly concave at the middle. In profile dorsum of mcso- 
notum and scutelhun Mat, latter truncate behind, metanotum level with 
posterior of scutcllum, declivity vertical, posterior corner projecting slightly 
giving a concave appearance. Node twice as broad as long, the anterior and 
posterior faces straight, broader behind than in front; in profile twice as 
high as long, anterior face convex and rounded into dorsum, posterior face 
flat or feebly concave, superior border sharp. Postpetiole one-fifth broader 
than long, no constriction between it and gastcr, the latter turned down with 
the terminal segments underneath, begs robust.

black ; mandibles, frontal carinae, antennae, legs and apex of gaster 
ferruginous ; in some examples the scapes and femora darker. 
Subopaque. Mandibles coarsely punctate. Head and thorax finely and 
densely punctate, some examples almostly finely reticulate ; gaster also 
densely punctate but more widely spread. Antennae and legs very finely and 
densely punctate. 
Hair yellow, fine, suberect, abundant but short throughout except on 
apical segments of gaster. Pubescence greyish, rather long, adpressed, abun- 
dant throughout but not hiding the sculpture. 
Head very slightly longer than broad, slightly broader behind than in 
front, sides convex, occipital border straight, angles rounded. Mandibles 
almost half as long us head, triangular, with teh to twelve strong sharp teeth. 
Clypeus very short, produced and convex in front, strongly carinate above, 
apex produced tooth-like on anterior border. Frontal carinae lobe-like, 
approximate, longer than broad. Scapes extending beyond occipital border by 
their thickness ; first segment of funiculus twice as long as broad, second to 
sixth slightly longer than broad, seventh to tenth as broad as long, apical twice 
as long as broad, as long as the 'wo preceding together. Eyes small, flat, 
placed at twice their diameter from anterior border. Thorax one and two- 
thirds longer than broad ; pro-mesonotal suture sharply impressed, meso- 
epinotal suture indistinct. Pronotum one-third broader than long, strongly 
convex. Mesonotum almost one-fourth broader than long, convex. Epinotum 
one-third longer than broad. In profile feebly convex longitudinally, pronotum 
descending abruptly in front ; declivity abrupt, rounded into dorsum, one- 
fourth longer than latter. Node almost three times longer than broad, strongly 
convex in front, flat behind, dorsum convex laterally ; in profile almost twice 
as high as long at base, anterior face straight, vertical, posterior slightly convex, 
inclined forward ; a long broad process in front below, with a sharp tooth 
directed behind. Postpetiole one-fourth broader than long, front and sides
