the process of suspension completed. Soon after this the chrysalis begins 
a series of wriggling and jerking movements to dislodge the empty larva 
skin, after the removal of which it remains motionless, unless disturbed, 
and becomes gradually harder and more contracted until it assumes the 
appearance represented by fig. 4. 
The chrysalis is about an inch long, and of a 
beautiful bright green colour dotted. with gold, and with 
a band of golden dots extending more than half way 
round the body above the middle ; this band is shaded 
with black. ‘There is a patch of black also arouud the 
base of the black protuberance by which it is suspended, 
and several dots of the same on other portions of the 
surface. 
The insect seldom remains in chrysalis more than 
ten or twelve days, and towards the latter end of this period, the hand- 
some ‘green and gold colours begin to fade, the chrysalis growing gradually 
darker until the diminutive wings of the future butterfly show plainly 
through the semi-transparent enclosure. The escape of the imprisoned 
insect, now nearly ready for flight, is usually made quite early in the 
morning. We have several times watched for their deliverance, and have 
usually found it to take place soon after daybreak. A sudden crackling 
and slight tearing sound is heard, which arises from a splitting of the 
-chrysalis case part way down the back, the fore legs, head and antennae 
are first withdrawn, and in a few moments the entire insect is liberated. 
At first the wings are very small, and the new born butterfly seeks at once 
some suitable spot where the wings may be held so as to hang down and 
thus facilitate the rapid growth which follows. This growth is truly 
amazing ; we have seen the wings double their size within three minutes, 
and seldom more than fifteen or twenty minutes pass before they have 
attained their full dimensions, and, ere the sun is high in the heavens, the 
soft, flabby wings have dried and the butterfly is ready for flight. ; 
The archippus butterfly, fig. 5, is so well known that it needs but litle 
_ description, especially when so good a figure is given. ‘The ground calour, 
‘of the wings, when fresh, is a beautifully bright orange red, the veins are 
heavy and black, and the margins are spotted with white, the latter being 
more or less covered or encroached upon by the general colour. Near the 
middle of the hind wings there appears in the figure on one of the veins
