in cocoons 20 , which were no doubt the female's first brood, this 

 being an incipient colony. 



Janet in 1893 isolated an old queen from a nest of aliena, which 

 he supplied with food, since she was past the age when a female 

 can subsist on her body -fat and wing-muscles. She laid eggs soon 

 after her isolation, and reared twelve larvae and a pupa in sixty- 

 one days, and five pupae and one worker in one hundred and two 

 days 18 . This queen lived in his possession for nine years, and during 

 the first year she reared about fourteen workers, during the second, 

 nineteen, the third, twenty-three, the fifth, sixth, and seventh, 

 a hundred, the eighth, forty, and the ninth, fifteen 29 .
