NEW AUSTRALIAN ANTS. 
margin of the eyes : first segment of funiculus longer than two following 
together, apical as long as three preceding together, Eyes circular, small, 
flat, placed at the posterior third of head. Ocelli minute. Thorax fully twice 
as long as broad. Pronotum as broad as long, strongly convex on the sides 
and in front. Mesonotum broader than long, the sutures well impressed. 
Epinotum as broad as long, sides parallel. In profile feebly convex longitudi- 
nally, the declivity almost as long as dorsum of epinotum, the boundary 
between them bluntly rounded. Node almost one-fourth broader than long, 
broader behind than in front, strongly convex in front and on sides ; in profile 
as high as long, the anterior face vertical, bluntly rounded into dorsum, the 
latter slightly convex ; a long, broad, projection in front below, with the 
anterior corner broadly rounded. Postpetiole almost one-third broader than 
long. A deep constriction between it and first segment of gaster, the latter 
broader than long. Legs short and stout. 
Habitat . — Tasmania : Trevallyn (V. V. Hickman). 
The female has been described in detail owing to the remark- 
able resemblance to the worker. It can only be distinguished 
by the slightly larger size, and possessing larger eyes and ocelli. 
All the known females of Amblyopone and Fulakora are winged. 
It is possible that the form described is not the true female, 
but with the exception of the thoracic segments it corresponds 
well with known females in the group. 
Genus DISCOTHYREA Roger 1863. 
Discothyrea leae , sp. nov. 
(PL II, fig. 11.) 
Female. — Length, 2.6 mm. approximately. 
Castaneous throughout. Pilosity yellowish, short and suberect, rather 
abundant, particularly on gaster. Pubescence very fine, short and adpressed. 
Head, thorax, and node subopaque, finely and densely punctate, the epinotal 
declivity shining and finely punctate. Gaster shining, densely punctate, the 
punctures larger and more scattered than on thorax. Antennae and legs 
finely and densely punctate. 
Head very slightly longer than broad, almost circular, the sides and occipital 
border strongly convex. Mandibles triangular, furnished with strong sharp 
teeth, the apex long and pointed. Clypeus short and truncate. Front of 
head projecting, overhanging the clypeus and mandibles. Frontal carinae 
short and erect, extending from front of frontal projection to near middle of 
eyes, swerving outward at middle then inward and approximate behind. 
Scapes short, greatly thickened to apex, their insertions exposed, extending 
a trifle beyond the posterior margin of eyes ; first segment of funiculus as 
long as the two following, apical twice as long as broad and as long as the 
six preceding together, these are broader than long. Eyes large, moderately 
convex, circular, placed at middle of sides. Ocelli large and convex. Thorax 
one and a half times longer than broad. Pronotum truncate in front, just 
visible from above. Mesonotum as long as broad behind, parapsidal furrows 
faintly indicated. Scutellum broader than long, convex behind. Epinotum
