striate and sparsely punctate, the clypeus densely transversely rugu- 

 lose. 



Pilosity pale yellow, much as in hedleyi 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 mjbhergi 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 mesoepinotal 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 

 mjohcrgi, the peduncle very small, the node very large, convex and 

 rounded in front and on the sides, with straight posterior border; 

 seen from above it is only a little more than 1^ 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, w^hich is large and shaped much as in the female 

 mjohcrgi. 



• Sculpture and color as in the worker, hairs considerably longer and 

 coarser, especially on the postpetiole and gaster. 



Queensland: Kuranda (Wheeler). 



I found onh- one colony of this ant (November 1), consisting of a 

 female and nearly 50 workers, but without larvae, in a small log in a 

 damp, shady spot in the dense "scrub." 



The worker is readily distinguished from both hedleyi and mjobergi 

 by its smaller size and less abruptly curved mandibles; from mjobergi 

 by its color, longer head, striated mandibles and finer pilosity; from 

 hedleyi by the straight dorsal outline of the thorax and less convex 

 pronotum, shorter petiole, scapes, and funicular joints.
