NEW AUSTRALIAN ANTS. 
almost to occipital border, giving the appearance of antennal grooves at each 
side of head. Scapes not extending to occipital border by fully their thickness ; 
first segment of funiculus longer than the two following together, second to 
seventh at least as broad as long, eighth and ninth longer than broad, apical 
longer than two preceding together. Eyes large, convex, projecting slightly 
at sides. Thorax almost twice as long as broad, sutures feebly indicated. 
Pronotum convex, bluntly produced, in front, marginate, the margin continued 
on sides, anterior angles sharply produced, but not spined ; dorsum almost 
flat, feebly convex. Mesonotum broader than long with a short stumpy 
tubercle at each side ; strongly constricted laterally and on dorsum, between 
mesonotum and epinotum. Epinotum one one-fourth longer than broad, sides 
convex and submarginate, posterior border with two long spines directed 
outward and backward, almost as long as the distance apart at base. In 
profile pronotum truncate in front, anterior angle sharp, marginate, inferior 
angle sharp. Mesonotum forming a single convexity with pronotum. Epi- 
notum convex, almost twice as long as declivity, latter convex, spines rather 
thick, directed backward and upward. Node about one-fourth longer than 
broad dorsum produced in front and sides to sharp angles which each bear a 
sharp spine directed upward ; in profile longer than high, anterior face almost 
vertical, convex, terminating above in a short sharp spine, dorsum straight, 
dropping behind, the; lateral spine longer and stronger than anterior spine, 
placed at middle of side ; ventral surface concave, with a long broad tooth in 
front directed forward. Postpetiole one and one-half times broader than 
long, oval ; in profile convex above. Gaster about one and one-half times 
longer than broad. Legs short and robust, femora towards base.

Head slightly longer than broad, sides convex, occipital boi'der almost 
straight, feebly convex, angles rounded. Mandibles furnished with four 
strong sharp teeth behind apex. Clypeus short, bicarinate, space between 
carinae concave. Frontal area triangular, feebly impressed. Frontal carinae 
extending almost to occipital border, forming inner boundary of antennal 
foveae. Scapes abruptly bent at base, not extending to occipital border bv 
their thickness ; first segment of funiculus longer than two following together, 
second to seventh broader than long, eighth and ninth as broad as long, apical 
longer than the two preceding together. Eyes convex, projecting slightly at 
sides, placed slightly in front of middle. 1 horax one and two-thirds times
