striate and sparsely punctate, the clypeus densely transversely rugu- 
lose. 
Pilosity pale yellow, much as in hedleyz but shorter. 
Color also like that of hedleyi, deep castaneous, nearly black; 
mandibles, except the teeth, clypeus, and frontal carinae deep brown- 
ish red; antennae, legs, and tip of gaster yellowish brown; coxae and 
middle portions of femora and tibiae darker. 
Female. Length nearly 4 mm. 
Resembling the female of mjébergi in form, but the head is pro- 
portionally broader behind and without lateral impressions; differing 
from the worker in the shape of the head, which is broadened in front, 
the feebly dentate, less curved mandibles and the stouter thorax and 
larger petiole, postpetiole, and gaster. The sides and dorsal surface 
of the pro- and epinotum are more convex than in the worker and the 
promesonotal and mesoépinotal sutures are more impressed so that 
the dorsal outline is much less straight and continuous. Mesonotum 
not more than twice as broad as long. Petiole like that of the female 
mjobergi, the peduncle very small, the node very large, convex and 
rounded in front and on the sides, with ou posterior border; 
seen from above it is only a little more than 14 times as broad as long, 
scarcely broader than the epinotum and more than half as broad as 
the postpetiole. The latter is separated by a very slight constriction 
from the gaster, which is large and shaped much as in the female 
mjObergt. 
Sculpture and color as in the worker, hairs considerably longer and 
coarser, especially on the postpetiole and gaster. 
Queensland: Kuranda (Wheeler). 
I found only one colony of this ant (November 1), consisting of a 
female and nearly 50 workers, but without larvae, i in a small log ina 
damp, shady spot in the dense “scrub.” 
The worker is readily distinguished from both hedleyz and mjébergz 
by its smaller size and less abruptly curved mandibles; from mjébergi 
by its color, longer head, striated mandibles and finer pilosity; from 
hedleyt by the straight dorsal outline of the thorax and less convex 
pronotum, shorter petiole, scapes, and funicular joints.
