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.

 landa (E. ]Mj6berg) ; Kuranda (Wheeler and F. P. Dodd). 



I took two small companies of this ant, unaccompanied by larvae 

 or females, Oct. 24 and 28, e\ddently 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.

JVorker. Length 3. .5-4 mm. 



Head subrectangular, not more than \ longer than broad, scarcely 

 broader in front than behind, with feebl\' 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 § 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 hedleyi in being stouter and in haAing 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 

 aboAe distinctly broader than long, with very convex sides. Con- 

 striction between the postpetiole and gaster somewhat deeper than 

 in hedleyi, legs stouter.
