B. 230. 



Aug. 18 2.00 P.M. I place a dealated queen of P. lucidus in Petri dish with two 

 dozen workers and 8 pupae of F. incerta. They attack her at once. She 

 tries to escape from them and usually manages to do so as she is very vig- 

 orous. She does not attack them, and bites them only when she cannot 

 get away. 



2. 20 P.M. 3 workers holding her, one by a leg and one by an antenna. 

 4.00 P.M. Still being held by 2 workers. 

 5.00 P.M. The same. 

 6.00 P.M. The same. 



Aug. 19 8. 20 A.M. 3 workers holding her on the sponge. This hostility was 

 continued against the queen until the morning of Aug. 23 when I found 

 her dead. 



Aug. 23 1.45 P.M. I place in another Polyergus queen. All but one of the 

 cocoons have hatched. Some of the workers escaped, but two have been 

 killed. There are now 15 workers in the nest and i of them is injured. 

 The injured one attacks the queen and is soon killed by her. None of the 

 other workers attempt to attack the queen. She runs about in the nest 

 and attempts to escape. 



4.00 P.M. 3 workers holding her, 2 by the antennae and I by a leg. 

 4.30 P.M. 3 workers are licking her. 

 6.00 P.M. I worker is holding her by a leg. 

 Aug. 24 8.00 A.M. 2 workers are standing by her side; they do not attack her 



and she does not avoid them.

 4.00 P.M. 3 workers are licking her. A few minutes later one of them holds 



her by the tarsus for a while. 

 Aug. 25 8.00 A.M. The Polyergus queen is dead. 



2.45 P.M. I place in another queen. 



Aug. 26 9.00 A.M. She is standing in the midst of the workers and seems to be 

 entirely uninjured. The workers do not attack her. There are several 

 dead workers in the nest. 

 11.45 A.M. She moves around with the workers and does not try to avoid them, 



nor do they avoid her nor show any hostility to her. 

 Aug. 27 8.00 A.M. The workers are standing all around her; there are 10 left 



alive. 



Sept. 12. I have examined the nest several times every day up to the present time 

 and have never seen her attacked. She has been fully adopted. 



B. 236. 



Aug. 19 1 1. 20 A.M. I place a Polyergus queen in one chamber of a nest containing 

 the mother queen, 16 workers and a few larvae and pupae taken from a large 

 colony of F. incerta. The Polyergus queen runs about in the nest trying to 

 escape. The workers are afraid of her and only a few try to attack her. 

 They gather up their pupae as they would in case of a raid. 



1.45 P.M. All but 6 of the workers escape past the cotton plug into the other 

 chamber. 



6.00 P.M. The Polyergus queen is standing by herself in a corner of the nest 

 The incerta queen and workers are standing in another corner with the brood.
