SIR JOHN LUBBOCK ON ANTS, BEES, AND WASPS. 617 



ceding experiments, and tlie ants began to clean tbem. At 8.30 

 they were all right. 8.45 do. At 9 they had been completely 

 cleaned, so that I could not distinguish them ; but there was no 

 fighting going ou in the nest. 



On the same day, at 9.45 a.m. I put into nest 64 two more as 

 before. At 10 they were both quite at home among the other auts. 

 10.15 do., 10.30 do., 11 do., 12 do., 1 do. I then put in a stranger ; 

 and she was at once fiercely attacked. 



Sept. 8. Put in two more of the auts which had emerged from 

 the pupse, as before, at 9.30 a.m. At 9.45 they were all right. 10 

 do., 10.30 do., 11 do., 11.30 do., 12 do., 1 do. 



On the other hand, on September 14, 1 put one of these ants in 

 the same manner into nest No. 60 at 6.30 a.m. She was at once 

 attacked. At 6.45 she was being dragged about by an antenna. 

 7 do. At 7.30 she was by herself in one corner. At 8.30 she 

 was again being dragged about. 9.30 do. The difierence, 

 therefore was unmistakable. 



Lastly, on July 29 I put some pupse oi Formica fuscafvom. out 

 of doors under the charge of three ants from nest No. 36. 



Aug. 8. Several had come out, and I put two of them into the 

 nest of their nurses (No. 36) at 2 p.m. Both were at once 

 attacked. At 2.45 they were being dragged about. 3 do. 3.30 

 one was being dragged about. 4, both were being attacked. 

 Eventually one was turned out of the nest. The other I lost 

 sight of. 



Aug. 4. Put two more of this batch into nest No. 36. at 12.30. 

 One was at once attacked. 1, one is being dragged about by an 

 antenna. 2.30, both are being attacked. At 2.45 one was 

 dragged out of the nest. 



I then put back one of the old ones ; as might have been ex- 

 pected, slie was received quite amicably. 



I then tried the same experiment witli another species, Lasius 

 n'lger. I took some pupse from two of my nests, which I knew 

 not to be on friendly terms, and which I will call 1 and 2, and 

 confided each batch to three or four ants taken from the other 

 nest. "When they had come to maturity I introduced them into 

 the nests as before. 



They were taken from their nest on the 20tli Sept. ; and the 

 results were as follows. 



Pupse from nest 1 confided to ants from nest 2. 



Sept. 20. Put one of the young ones into nest 2 at 7.15 a.m.
