Butterfly.-This familiar insect needs no description. It is well known to every boy in the north temperate zone. It is one of the commonest as well as one of the most beautiful species of the tribe. A rare aberration in which the yellow border invades the wing nearly to the middle, obliterating the blue spots, is sometimes found. The author has a fine example of this "freak."

The eggs are laid in clusters upon the twigs of the foodplant in spring. There are at least two broods in the Northern States. The caterpillars feed on willows, elms, and various species of the genus Populus.
