was pulled about at once by the workers, and shortly after carried 

 into the crowded chamber and lost sight of. Next day her 

 body was found cut up and given to the larvae as food. 



Experiment III. — On July 25th he put another deälated 

 female into the same nest of Tetraynorium. A worker carried her 

 into the next chamber at 8.30 a.m. At 9.0 a.m. she was walking 

 about and occasionally attacked. She then seized a worker by 

 an antenna and pulled her along. Later she was again attacked, 

 though some workers cleaned her. At other times she was 

 carried about all doubled up. At 10.30 she was free. The nest 

 was unfortunately left in the sun, and at 12.30 p.m. the female 

 was found dead and cut in two. The workers had probably 

 become unduly excited by the heat of the sun, to which they 

 were unaccustomed. 



Experiment IV. — Crawley had a large colony of Tetramorium 

 from Seaton, Devon, in a Janet nest. It was obtained in 

 June 1912, and consisted of over 1,000 workers, a large number 

 of winged females and males and pupœ. 



On July 17th one of the females removed her wings, and 

 two days later another did the same. These females were 

 from time to time caressed by the workers, and may have been 

 fertilised in the nest. This point is important in view of the 

 experiment, as the nest contained no old fertile queen. 



At about II a.m. on July 25th he placed a deälated Anergates 

 female, holding a Tetramorium worker by the antenna tip, into 

 the light chamber of this nest. A worker at once attacked the 

 captive worker. At 11. 15 the female was held by the back 

 of the thorax, but her captive was not attacked. At i p.m. 

 she was in the next and dark chamber, unmolested and still 

 holding her worker. Later she was surrounded by about twenty 

 ants, and her captive had gone. At 6.15 p.m. she was in the 

 innermost chamber with a large court of workers round her. 

 Next day the female seemed to be definitely accepted as queen 

 by the Tetramorium workers, some of whom were in constant 

 attendance on her. On the 28th her abdomen was distended 

 so that white showed between the segments. On July 30th 

 both of the deälated Tetramorium females in the nest were being 

 attacked by their own workers. Presently they were brought 

 out into the light chamber. Next day they were dead, and
