272 WHEELER. 



Subopaque, very finely and densely shagreened ; mandibles slightly 

 shining, coarsely punctate along the apical margin. 



Pubescence extremely short and fine, less distinct than in erythro- 

 cephalus, covering the body and appendages. Hairs as in erythro- 

 cephalus. 



Rufotestaceous throughout, except the gaster which is black, with 

 bluish or greenish reflections.

Neio Guinea: (Burgers). 



This is the largest of the species of Leptomyrmex. September 20 I 

 found a fine colony in a large rotten Eucalyptus log near Katoomba. 

 The nest cavity was in the center of the log and about five inches in 

 diameter. It contained about 200 workers and many pure white larvse. 

 Aljout one in six of the workers was in the replete condition. Each of 

 these repletes, when the nest was disturbed, seized a larva and stalked 

 out of the nest, and did not quicken its pace unless touched. A few 

 workers on the road in a different locality near Katoomba were seen 

 dragging an earthworm two and one half inches long to their nest. 



The citation of this ant from New Guinea by Stitz seems to me 

 to be very doubtful.

Differing from the typical form in having the tibiae more strongly 

 compressed; and with both these and the tips of the femora black. 

 The tint of the testaceous portions of the body is deeper. The head

Worker. Length G.5-8 mm.
