moves the limb they are operating on. At last the patient is 

 set upon its legs, and no farther notice is taken of it. It is 

 now a very pale coloured Ant, moves languidly about the nest 

 for some time, then it begins. to feed itself on the fungus, and 

 the next day is busy at work in the nest, which it does not 

 leave till it has acquired the proper Ant colour, and can no 

 longer be distinguished from the others. 



My '' B " nest had neither queen nor male when it was 

 set-up on the 4th July, a few larvai and pupas were put into the 

 neit at starting. The last of these became an ant on the 14th 

 August, 41 days after capture. 



The first eggs were seen 19 days after the cajiture, viz., on 

 the 23rd July. Very many small, medium sized, and large ants 

 were matured from these eggs before its destruction on the 6th 

 November, in periods of from 57 days for the smallest to 74 days 

 for the larger ones. On the 20th October a male was matured, 

 on the 3rd November there -were 25 males On the 2nd 

 [November a queen was matured, and another on the 5th, three 

 days later, and their period Avas about 84 days. Thus, there are 

 about 10 days for the egg, as a larva it varies from 27 days for 

 the smallest workers, 44 days for the ordinary workers and 54 

 for males or queens, and 20 days for the pupa stage. 



To prevent these flying ants escaping from the nest, I put 

 a small mosquito net over it, Avhich, whither from the wind, or 

 by accident, touched the upper part of the nest. On the morn- 

 ing of the sixth I found that Foraging Ants had entered the 

 nest and completely destroyed, it during the night. The 

 marauders had entered at the point where the net touched, by 

 eating a hole through it, and must have trooped in, iu considerable 

 numbers as most of the ants had been carried off Curiously the 

 exact number of wings of both males and queens were left in 

 the nest. I counted them carefully and found 108 wings, or 

 four for each winged ant F'our parasol ants of the larger size, 

 although dead, were still holding on to four of the foraging ants. 

 There were still in the nest 21 others which had been left behind 

 when the army retreated The fungus bed was scattered here 

 and there, as if it had been done by some malicious person. 



I have not yet been able to name the foragers, but they are 

 the ones that live in orchids, having a black head and body Avith 

 an almost transparent abdomen. 



When the nest was destroyed there were still four queens 

 and two males as pupaj to mature, besides a vast number of 

 larvie and pupce of the various sized ants.
