leaves, of which the three remaining weakened specimens at once began 
to eat ; two of them soon became plump and active, but the ‘other died. 
After the first moult, the following description was taken : — 
Length ws of an inch. Head medium size, dark brown: second 
segment pale on its anterior edge, brown behind, third segment brown 
also, the remainder of body being very pale brownish, with several round 
greenish-white spots on each segment. ‘There is also, on each segment, 
a transverse row of pale slightly raised dots, from each of which arises a 
single brownish hair. 
By the 16th of July, the larve had again moulted, and had now grown 
to a quarter of an inch in length, and were thus described: 
Head small, bilobed, black and shining, with a few short pale brown- 
ish hairs, 
Body above brownish-black, dotted and spotted with greenish. Second 
segment with a transverse row of tubercles, from which arise brown or 
blackish hairs. Third and fourth segments each with four black branch- 
ing spines ; spines and branches all nearly black. From fifth to twelfth 
inclusive, each segment has six spines, the two upper pairs of which are 
black, tipped with greenish, and with a little greenish colour at base, the 
fine hair-like branches being black or brown. The lower pair of spines 
are set in a band of pale greenish-white ; where they partake of the same 
colour, both spines and branches, and this greenish-white stigmatal band, 
has a broken brownish line running through it. On twelfth segment is an 
additional dorsal spine, placed a little behind the others ; terminal seg- 
ment with four spines arranged in two pairs, one above the other. 
Under surface paler and greenish. Feet tipped with black ; prolegs 
pale semi-transparent. 
Soon after this date, one of these larvæ escaped from confinement, 
and could not again be found ; the other soon ceased feeding, and be- 
came lethargic, and still continues so, but whether alive or dead now I 
can scarcely tell, although I fancy it is still living. From the observa- 
tions of Mr. Scudder on Argynnis bellona, published in the September 
number of the American Naturalist, and also from remarks made in cor- 
respondence by Mr. Edwards, who has closely watched many members of 
this interesting family, as well as from my own observations, it seems 
highly probable that most, if not all of our species of both Avgynnis and 
Mélitea, pass the winter in the larval state, the larve becoming lethargic 
while quite young.
