COLIAS II., III. 
I have bred, a male and a female, were from larvae which had these spots largely 
developed. Both are dark lemon-yellow above, and of a rich shade beneath, 
heavily dusted. In the male (Fig. 5, PI. 1.) the discal spot on under side of 
piimaiies is red-centred, and the fringes on upper side are roseate throughout, 
not mixed with yellow as is usual. The other butterflies of the brood were in 
no way singular. 
About Coalburgh, Philodice appears early in May, and is on the wing in sue- 
cessive generations till about the first of November, by which time severe frosts 
destroy them. The eggs are deposited upon the clover leaves, a single one to a 
plant, and the females may often be seen flying about the lawn or meadow for this 
purpose. I have not attempted to obtain eggs in confinement upon other food- 
plants attributed to the species, but Mr. Dodge has succeeded with the buffalo- 
pea, Astralagus caryocarpus, which grows on the prairies, and is one of the plants 
on which the larvae of Eurytheme feed. The young larva; are at first rather dif¬ 
ficult to manage, having a disposition to roll off the leaves, and are apt to be lost 
in the breeding-cage. I have succeeded better when inclosing them in covered 
glass vessels, changing the leaves frequently. This tendency to drop at the least 
disturbance the larva; retain till maturity, and it is naturally their sufficient pro¬ 
tection against enemies or destruction. They lie exposed on the upper surface of 
the clover leaf, and resemble its color closely. When first from the ego- each 
makes for itself a hole in the leaf, and feeds at the edges of this for several days 
( '8 s - l: - d,), but as it increases in size it devours the leaf from the end or 
side. As the time approaches for the change to chrysalis, the larva seeks the 
protection of some stem, bit of bark, or fence rail, spins a button of pink silk and 
a light web over the surface of the object, fastens its anal feet in the one and its 
oi elect, ill the other, and hangs with its. back curved downward or outward 
Gradually the markings of the body become obliterated, lost in uniform green 
In tins condition the larva rests for some hours, then rousing itself, spins a 
loop of several threads from the base of the feet on one side to a like point on 
the other, instinctively knowing just how long to make the threads, and pres¬ 
ent y, seizing the loop m its jaws, manages to throw it partly over the head, and 
>y a great effort works it entirely over and down the back to the fourth seg¬ 
ment and stops exhausted. Some hours pass without any motion, when suddenfy 
the skin splits on the back of the anterior segments and is rapidly shuffled off' 
exposing the chrysalis, which rests secure on its girdle of silk. 
the latest broods of larvae, or those which are caught by cold weather before 
they have matured, hybernate more or less, and further south this may be the 
ha at Twice I have carried half-grown larvae through the winter. Mr. Mead 
ound hybernating larvae inactive under boards, in the month of May, in Illinois.
