6o 



of F. sanguínea from Woking in a chamber of a Janet nest 

 next to one containing six workers and pupae of F. fusca v. fusco- 

 rufibarbis, frorn Seaton, Devon. After once wandering into their 

 chamber and being chased out, she did not leave her own chamber. 

 On the 17th her wings were artificially removed. Next day she 

 was dead in the fusco-rufibarbis chamber. 



At 3.45 p.m. on July 19th a virgin artificially deälated female 

 of F. sanguínea from Woking was placed in a chamber adjoining 

 the same F. fusco-rufibarbis workers and pupaí. At 4.20 p.m. 

 she was seen to be carrying a pupa into her chamber, which 

 now contained eight pupae. Three of the five workers and a male 

 recently emerged were also in her chamber. She then entered 

 the other chamber and attacked a worker, who escaped from 

 her. Another worker, who tried to take away a pupa she was 

 carrying, was killed. At 4.35 she had killed another, and both 

 this and the other dead one were hanging to her legs. She 

 pranced about the nest with open jaws whenever light was 

 let in. At 8.0 p.m. she killed another worker and chased the 

 remaining two. Next day she was repeatedly attacked by the 

 two workers, but never attempted to retaliate, and up to July 31st 

 she has never attacked the workers again, though they occasionally 

 pull her antennae and legs. 



On July 25th a similar deälated female of F. sanguínea was 

 placed in the light chamber of a nest of F. fusca, containing a 

 queen, over one hundred workers, and pupae taken some years 

 ago in the New Forest. She was immediately seized and over- 

 powered, and made no resistance. Another put in the same 

 nest shortly afterwards was overpowered and killed. 



Another was placed in the light chamber of a nest containing 

 eight queens, about 130 workers, and pupae of F. fusca v. glebaria, 

 from St. Issey, Cornwall. She was at once overpowered and 

 killed. Another the same day was placed with ten workers 

 of F. fusca and a number of pupae from the New Forest. She 

 was found dead a few hours later. 



Again, on July 25th, a similar female was placed in a glass- 

 topped box containing two workers and a quantity of pupae 

 and one callow of glebaria from the New Forest. The two 

 adult workers immediately seized two pupae and fled to the top 

 of the box, where they remained, holding the pupae for two days
