WHEELER: AUSTRALIAN ANTS. 51 
somewhat longer and sparser on the thorax, abdomen, and legs than 
on the head and antennae. 
Black; thoracic sutures, sides and terminal segments of abdomen, 
clypeus, cheeks, and anterior portion of gula reddish castaneous, 
mandibles, except their teeth, antennae, and legs paler, brownish red, 
middle portions of femora and tibiae more or less infuscated. 
Queensland: Mt. Bellenden-Ker, type locality (Podenzana); Ma- 
landa (E. Mjéberg); Kuranda (Wheeler and F. P. Dodd). 
I took two small companies of this ant, unaccompanied by larvae 
or females, Oct. 24 and 28, evidently on foraging expeditions in the 
heart of rotten logs. One of the companies comprised a dozen, the 
other about two dozen workers. Later Mr. Dodd sent me eight 
workers which he had taken in the same locality. The ants moved 
rather slowly and were easily captured.

Worker. Length 3.5-4 mm. 
Head subrectangular, not more than j longer than broad, scarcely 
broader in front than behind, with feebly and evenly convex sides, 
feebly concave posterior border and rounded posterior corners. 
Clypeus with broadly arcuate anterior border, sinuate on each side, 
minutely and evenly denticulate. Eyes scarcely smaller than in 
hedleyi, situated about § the distance from the anterior to. the posterior 
border of the head. Mandibles similar to those of hedleyi. Antennae 
shorter, scapes only 2 as long as the head, first and last funicular joints 
nearly twice as long as broad, remaining joints not longer than broad, 
the more basal joints a little broader than long. Thorax differing 
from that of hedleyz in being stouter and in having the dorsal outline 
nearly straight in profile, the pronotum being convex only at the ex- 
treme anterior end and the mesonotum less impressed. Thoracic 
sutures very distinct but less impressed than in hedleyi. Mesonotum 
fully three times as broad as long. Petiole with very short peduncle, 
anterior surface of node more concave, its upper surface seen from 
above distinctly broader than long, with very convex sides. Con- 
striction between the postpetiole and gaster somewhat deeper than 
in hedleyi, legs stouter.
