NEW AUSTRALIAN ANTS. 
Smooth and shining, with moderately large, piligerous punctures, abundant 
throughout. 
Hair white, long, suberect, most abundant on apical segments of gaster- 
Pubescence white, fine, sparse throughout. 
Head as long as broad, sides and occipital border feebly convex, angles 
rounded. Mandibles broad, edentate. Clypeus very short. Frontal carinae 
converging behind. Scapes extending to near posterior margin of eyes ; first 
segment of funiculus as long as broad, second to tenth broader than long, 
apical barely twice as long as broad and fully as long as the two preceding 
together. Eyes large, circular, rather flat, situated at middle of sides. No 
ocelli. Thorax one and three-quarters times longer than broad, without traces 
of sutures, feebly compressed at the mesonotal region, borders bluntly rounded ; 
in profile feebly convex longitudinally, the declivity short, at an oblique angle, 
rounded into dorsum above. Node one-fourth broader than long, broader 
behind than in front, sides convex and feebly marginate, anterior border 
concave, angles sharp, posterior angles produced as short, broad teeth ; in 
profile longer than high, anterior face vertical, dorsum strongly convex, strong 
sharp hook-shaped tooth in front below, directed backward. Postpetiole 
very slightly broader than node, slightly broader than long, sides convex ; 
a deep, but not wide, constriction between the postpetiole and first segment 
of gaster, the latter one-fourth broader than long. Pygidium concave, sides 
submarginate and bearing a row of short sharp bristles. Legs robust. 
Habitat. — N. Queensland : Kuranda (F. P. Dodd). 
Type in .South Australian Museum. 
Readily distinguished from all the known species bv the 
lack of margins to thorax. 
Phyracaces pygmaeus, sp. nov. 
(PI. II, fig. 7.) 
Worker. — Length, 2.8-3 mm. 
Head brown, gaster black ; pronotum and node ferruginous ; meso- 
epinotum and postpetiole castaneous ; antennae and legs ochraceous. 
Smooth and shining, with large, scattered, shallow piligerous punctures, 
abundant throughout. 
Hair yellow, long and suberect, abundant throughout. Pubescence hardly 
apparent, very fine and adpressed. 
Head slightly longer than broad, sides feebly convex, occipital border almost 
straight. Mandibles edentate, with sharp cutting borders. Frontal carinae 
narrow and parallel, truncate and approximate behind ; carinae of cheeks 
strong, extending to anterior third of eyes. Scapes extending slightly beyond 
posterior margin of eyes, gradually thickened to apex ; first segment of 
funiculus barely as long as broad, second to seventh almost twice as broad as 
long, eighth one and a half times broader than long, ninth and tenth slightly 
broader than long, apical twice as long as broad and as long as the three 
preceding together. Eyes large and rather flat, almost one-third the length 
of sides, situated in front of the middle. No ocelli. Thorax one and three- 
quarters times longer than broad, sutures faintly indicated, feebly constricted 
at the mesonotal region. Anterior border of pronotum convex and marginate, 
angles rounded, posterior border of epinotum straight and marginate, angles 
sharp ; sides of thorax rounded, not marginate. In profile evenly arched 
longitudinally, declivity flat, at an oblique angle, sides submarginate. Node
