WHEN REMOVED AS PUPA. 1435

afterwards one of the others was also seized, but let go 
again almost immediately. At one o’clock they were 
all right, and also at two. They had, however, in the 
meantime been more than once threatened, and even 
momentarily seized, though they were never dragged

I found one of them dead; but I think I must have 
accidentally injured her, and I do not believe that she was

and had been partly cleaned. At six one of them was 
running about comfortably amongst the rest ; the other 
I could not distinguish ; but certainly no ant was being 
attacked.

to Formica fusca and Lasius niger, removed from
