vigorously. It seemed to be conscious of its imprisonment, and appeared so eager to 

 escape, it made me feel uncomfortable, so I opened a hole in the cocoon, out of which it 

 crawled on to a finger which I extended for its convenience, thus missing an opportunity 

 of seeing it dig its own way out. It was perfectly dry, and left no moisture on the 

 cocoon or pupa case. I gave it a position to suspend from, where I could observe it 

 conveniently. I looked at the time ; it was a quarter to three. It did not show the 

 slightest inclination to travel.

rRhMuiThe abdomen was fully extended, green in colour "with, comparatively, narrow white 



Isands around it. The front winglets were about three-quarters of an inch in length, 



the hind ones less, clothed with hair-like scales, slightly tinged with yellow, sufficient 



to contrast with the pure white of the body covering. The tail was bent round and laid 



along the outer angle of the hind winglet, as shown by part h on Fig. 21, 



which gives a moderately correct representation of it on an enlarged 



scale. At five minutes to three a green spot appeared near the base 



of front winglet, gradually enlarging as the fluid spread between the 



membranes, and deepening in colour as the quantity increased. At three 



o'clock the green had reached the eye spot on the front wing, and the 



maroon colour of the costal band. At 3.10 the wing was one inch and a 



half long. By this time the fluid was passing rapidly along the costal 



edge and extending, whilst the outer angle had not yet begun to extend ; 



the result was the apex drawn back, the membrane of the wing bulged 



and bagged outward. At this time the hind wing had got a green tinge 



along the outer margin, which was extending. At 3.20 the outer angle of front wing 



had relaxed somewhat, which allowed the costa to straighten and reduced the bulging. 



3.35— the front wing looked to be full length, but not full width. 3.45— hind wing 



well expanded and green coloured ; part b on Fig. "21 had moved away slightly from part a.
