APATURA II. 
ceased to feed and partly changed color, again began to eat, though the leaves 
in their glass were thoroughly dry, and some time towards the last of September 
passed the third moult. Not anticipating this 1 discovered the change accident¬ 
ally, and was surprised at finding them active, and of a brilliant green color. I 
ia\c> since learned from Mr. Riley’s paper, before cited, that lie had watched 
arvat oi Clyton when this third autumnal moult was taking place, thoindi his 
experience agrees with mine that such instances are exceptional. These Iarvte 
again changed color, but to nothing like the degree of the others, becoming 
greenish-brown or vinous-brown, and no shrinkage of the body was perceptible 
And at intervals through the winter, a few moments in a warm room would 
arouse them Unfortunately two of these died before spring, and the third was 
accidentally killed.

On 9th May following, the shoots of the Hackberry beginning to put forth I

exposure Some began at once to move and eat, and of these part turned 
gieen within the next twenty-four hours. Others remained quiet, and changed 
gradually to pale vinous and then to green, taking three or four days to make 
the complete change. But others still occupied several days more.

' moult which took place on 23d and 24th. By 30th May these were in chrys¬ 
alis, and the butterflies appeared on the 10th June and days following. Mean- 
nne some of the larvae continued to grow and reached a size which seemed 
cnoi moils lor this species. And it turned out that all these large Iarvte produced 
elUa e but ‘ erflles - and no female appeared until nearly all the males had 
tineiged. I have not noticed this peculiarity, nor have I been able to distin- 
guish the sexes by the size of the caterpillar, in any species but the present one.
