SIR JOHN LUBBOCK OS ANTS, BEES, AND WASPS. Gl7 



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

 they were all riglit. 8.45 do. At 9 they had beeti completely 

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

 fighting going on in the nest. 



On the same day, at 9.45 a.m. I put into nest G4 two more as 

 before. At 10 they w^ere both quite at home among tlic other ants. 

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

 and she was at once fiercely attaclced. 



Sept. 8. Put in two more o£ tlie ants which had emerged from 

 the pup.T, 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 G.30 a.m. She was at once 

 attacked. At G.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 difference, 

 therefore was unmistakable. 



Lastly, on July 29 I put some pupae of Formica fusca ivom out 

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



Aug. 3. Several had come out, and I put two of them into the 

 nest of their nurses (No. 36) at 2 p.m. Boih 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, she was received quite amicably. 



I then tried the same experiment wdth another species, Lashis 

 niger. I took some pupae from two of niy 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 20th Sept. ; and the 

 results w^ere as follows. 



Pupae 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.
