PONEEID^. 

 ECTATOMMA DIMINUTA, Smith. 



These marauding ants from Cairns, Queensland, appear to have 

 no settled home, but roam about in masses, sometimes together 

 and sometimes separating into small companies. They attack 

 any insect they meet with, hunting their victims from under the

 to them, and no insect appears to escape them. 



Cetptocekid^.

These harvesting ants are found at Mackay, Queensland. 

 They climb up grasses, and carry away the seed to their nests. 

 The ground near the nest is generally strewn all over with the 

 husks they have brought to the surface.

 apparently arrived in larger numbers than usual, so that Mr. 

 Power had a chance of securing a good series for his collection ; 

 he having sent me a dozen examples to preserve, ajQforded me an 

 opportunity of making a few observations, which I now append. 



The relative lengths of the bills and tarsus in the above, with 

 one exception, varied so slightly as to be scarcely perceptible,
