fusca nest, plundered it without opposition and at once returned home 

 with all the pupx that could be secured. The main army hurried on 

 over a very rough, stony trail. They stopped twice, searched aboui 

 diligently but in vain, and each time changed the direction of their 

 route. Several completely or partially dealated females accompaniea 

 the main army the whole distance and seemed to be quite as keenly 

 interested in the proceedings as the workers. The army halted a 

 third time at a spot 125 feet distant from the point where the first 

 nest was plundered and succeeded in discovering a flourishing fusca 

 colony consisting of large workers. These were very aggressive and 

 fully prepared to defend their nest, which, like all the fusca nests in 

 the vicinity of the amazon colony, was very carefully concealed under 

 and between stones. The amazons reached this nest at 4.30 P. M. 

 and exhibited great excitement. Some of them attacked the fusca 

 fiercely, while others kept digging their way into the earth-barricaded 

 entrances. Fusca workers could be seen defending their doorways 

 from within, but they were mercilessly dragged out and massacred 

 in the usual manner, by having their heads pierced with the sickle- 

 shaped mandibles of the amazons. Finally, after a struggle of fully 

 30 minutes, at 5 P. M. the first fusca pupae were brought out. Their 

 bearers turned at once in the direction of their nest, nearly 200 feet 

 away and hurried towards it over a path, which, for fully 40 feet, 

 was entirely different from the one over which they had come. A 

 stream of pupa-laden amazons issued from each of two nest orifices 

 and at once united to form a single file. Even the young callow fiisca 

 workers were dragged out by the antennae and then seized by the 

 thorax and carried along. Several of the dealated females returned 

 with the workers but none was seen to carry a pupa. The army 

 reached the home nest at 5.30 P. M., so that this foray, during which 

 two fusca colonies had been thoroughly plundered, and fully 400 feet 

 of ground had been traversed by most of the individuals, was com- 

 pleted in two hours. 



July 28. The amazon army left the nest at 4.15 P. M., plundered 

 a large fusca colony after traversing nearly 80 feet of rough, stony 

 soil to the southeastward, and returned with many pupae by 5.30 P. 

 M. The army was accompanied both to and from the fusca nest by 

 several dealated females, but none of them carried pupae.
