in the earth and built up a roof covering them completely in. 

 Ten days later the cell was opened and found to contain a 

 quantity of eggs. 



One of the females was then placed with four workers from a 

 queenless colony, but she killed them all. Another female was 

 then placed in the light chamber of the queenless nest, and in 

 a few minutes was found on her back attacked by a score of 

 workers, and so was removed. The three females were then 

 re-united and placed in a four-chambered plaster nest with a 

 large number of pupae and a few callows. One female immediately 

 began to carry the pupae into a dark chamber, and though 

 assisted for a short time by another female, carried over one 

 hundred pupte herself. Several mature workers, hatched from 

 the same lot of pupie, were put in the nest, but they were killed 

 at once by the females, who had not, however, molested the 

 callows. Next day each female occupied a chamber to herself 

 with pupœ, the energetic female, distinguished as A, having by 

 far the largest number. On August 2nd one of the other two 

 females was dead, and in A's chamber. At this time about 

 150 workers had emerged, and the females had laid eggs and 

 ceased to work. On August 4th some workers began to attack 

 the other female, and though a few saluted and caressed her, 

 she was killed. Thus the female A was left as the sole queen 

 of the colony. 



Again, on July 22nd, at Sea View, Crawley took three 

 deälated females of nigcr and placed them together in a box 

 with damp earth and no food. On the 24th they laid eggs, 

 and next day one excavated a cell by herself and covered herself 

 in. The other two remained outside with their eggs. A week 

 later these two had also disappeared under the earth and left 

 no trace. 



On August 23rd the cell excavated by the ñrst female was 

 carefully opened, and found to contain all three females, thin 

 but active, with a quantity of very small pupae, some larvœ, and 

 eggs. The breach in the roof of the cell was quickly repaired 

 by the females, and the box was left untouched until September 

 9th. The cell was then seen to contain, besides the three females, 

 pupie, and larvie, two very small mature workers and twelve 

 callow worker?. This was forty-eight days since the first eggs
