without having been observed to move. The F. sanguínea 

 female took no notice of workers or pupœ till the next day, when 

 she collected the pupae together and rested on them with the 

 callow. More callows hatched from day to day, and the two 

 mature workers were found dead on the 28th. By the 31st 

 there were ten callows with the female on the pupas, and all 

 were on good terms. 



On July 27th another deälated female was placed in the light 

 chamber of the nest of F. fusca with queen and a hundred workers. 

 She remained in a corner for two days, and the F. fusca workers 

 blocked up the entrance to the next chamber. However, on the 

 third day they came out and killed her. 



DONISTHORPE, on July 2nd, 1912, took one of the tame 

 queens out of his observation nest of F. sanguinea and put her 

 in the light chamber of a four-chambered Janet nest. The 

 nest contained a colony of F. fusca from Porlock, consisting of 

 two F. fusca females, man}- workers, and a large number of 

 cocoons, which occupied the second chamber. In the third 

 chamber, the one next to the F. sanguinea female, a number of 

 the F. fusca cocoons were placed and the passage to the F. fusca 

 apartments was blocked up with cotton-wool. The F. sanguinea 

 female soon entered the third chamber and sat on the pupae. 

 On Jul}' 3rd she was still on the pupae, and the cotton-wool was 

 removed. Some of the F. fusca workers entered her compart- 

 ment. Some threatened her, and ran away, but others attacked 

 her, and others again took away the cocoons. She killed two 

 workers during the combat. The F. fusca workers then retired, 

 and she was left alone. Later the female was placed in the 

 compartment occupied b}' the whole F. fusca colon}'. Nearly 

 all the ants bolted, but a few workers attacked her. She escaped 

 and returned to the light chamber. She never tried to enter 

 the nest again, and her one desire appeared to be to escai)e, 

 and subsequently three or four workers came in and fastened 

 on to her legs and antennœ. As it was feared she would be killed, 

 she was then returned to her own nest. Here she was i)ulled 

 about by her own workers for the rest of the day, but on the 

 following day she was treated as usual, and is still alive and well. 



On July 8th a F. sanguinea female from Bewdley Forest 

 was placed into the Porlock F. fusca nest among the ants. Most
