spots near together, one smaller than the other, surrounded 
by a rust-colored ring. There is a row of dark points more 
or less evident, within, and parallel to the outer margin, on 
the under side of all the wings. 
A female variety is sometimes found with wings nearly 
white. 
The larva of this insect feeds on clover, medicago, lucerne, 
buffalo pea, and sometimes on the leaves of peas. 
The eggs are deposited on the upper side of the leaves, one 
only on each plant, and are pale yellow when first 
deposited, but change in a few hours to a dark 
crimson color. They are spindle-shaped, .06 of an 
inch long, attached by one end, ribbed lengthwise

and crossed by numerous strie. The eggs hatch Fig. 10, 
in six or seven days, and the brownish green larve — ge of 
at first eat round holes through the leaf, but later Colas philodice 
eat the entire leaf from the outside. a 
The larve molt their skins four times before they reach 
maturity, when they are a little over an inch long, cylindrical, 
slightly tapering towards the last segment, 
downy, of a dark green color, somewhat 
lighter underneath, with a creamy white 
stripe on each side, through the middle of 
which runs a broken crimson line, below 
which there is sometimes a series of black 
spots. After they are done feeding, they 
seek some protected place where they spin 
a button of silk, to which the anal feet are 
attached, and a loop in which the body is 
supported ; and after a little time the old Fig. 11 Colias philodice.

From the laying of the egg to the emergence of the but- 
terfly in the warmest part of the season is about forty days, 
and as they are to be seen on the wing from the last of May 
till the last of September, it is probable that we have three 
broods in Maine. This insect is extremely abundant in this
