fierce big-headed soldiers; as odd a contrast as the fresh creamy 
whiteness of the opening wing, the flash of purple and blue, and 
_ the sparkle of green and silver eyes is to the darkness and dinginess

gained strength to fly away, they remain hovering over the nest. 
A larva of a species of Catopsilia [one of the Pierince or ‘ Whites’] 
I threw down as an experiment, was immediately set upon and torn 
to pieces in a second by the ants.” 
“JT took a T. theophrastus larva from a tree, and introduced it‘on 
the pathway of another company of the same species of ants who 
lived in our verandah, but kept no ‘farm,’ and it was odd -to see the 
ants come tumbling out headlong to fight the intruder, and the 
sudden way they cooled down on investigation of the foe. None 
attempted to harm him, and he was politely escorted across their 
boundary, the ants running alongside, and feeling him all over 
with their antenne. This must have been instinct, as they could 
-have had no former knowledge of himas a “milk-giver.” The dead 
chrysalids in an ants’ nest are carefully removed and thrown away 
outside ; the ants also distinguish between the dead and living.”
