NEW AUSTRALIAN ANTS. 
broader than long, sides and anterior face united in a hemi-circle, posterior 
border concave, in profile higher than long, anterior face straight, posterior 
face strongly convex, rounded into dorsum. Postpetiole one-fourth broader 
than long, anterior face straight, truncate, sides feebly convex. First segment 
of gaster one-fourth broader than long, as broad as behind, feebly convex. 
Legs short and robust. 
Habitat. — N. Queensland : Cairns (Dr. W. M. Wheeler, 13-10-14). 
Apparently near E. astuta Smith, the only other species in 
this genus recorded from Australia, but smaller and differently 
sculptured. Described from a specimen received from Dr. 
Wheeler.

Worker. — Length, 5.6 mm. 
Head, dorsum of thorax and gaster brownish black ; mandibles, sides of 
thorax and node ferruginous ; antennae and legs castaneous. 
Opaque. Mandibles, antennae and legs very finely and densely punctate. 
Head, thorax and gaster finely and densely reticulate, node more coarsely so 
and more shining. 
Hair yellow, short and suberect, moderately abundant throughout except 
on antennae and legs. Pubescence yellowish, fine and rather dense throughout 
but by no means hiding the sculpture. 
Head almost one-fourth longer than broad, slightly broader behind than 
in front, sides feebly convex, occipital border straight. Mandibles triangular, 
edentate, apex long and slender. Clvpeus broadly rounded in front, raised 
abruptly level with top of frontal carinae ; latter flattened, lobe-like, over- 
hanging but not hiding the antennal insertions, not as long as wide in front. 
Frontal groove short. Scapes extending beyond occipital border by fully 
their thickness ; first segment of funiculus longer than second and third, 
fourth to tenth as long as broad, apical twice as long as broad. Eyes convex, 
placed at middle of sides. Thorax one and three-quarters times longer than 
broad. Pronotum one-third broader than long, sides and front convex, suture 
sharply defined. Meso-epinotal suture weakly defined. Posterior margin of 
epinotum feebly concave. In profile convex longitudinally, declivity abrupt 
and straight, sides feebly margined. Node almost one and one-half times 
broader than long, sides and anterior border convex, posterior border straight, 
dorsum flat with a strong central longitudinal carina ; in profile one and one- 
fourth times higher than long, anterior and posterior faces straight, ventral 
surface convex, with a short blunt tooth behind directed backward. Post- 
petiole one and two-thirds broader than long, strongly convex in front and
