Although all the Psyches wear this threefold garment, the different species make distinct variations in the outer case. There is one kind, for instance, whom I am apt to meet towards the end of June, hurrying across some dusty path near the houses. His case surpasses that of the first species, both in size and in regularity of arrangement. It forms a thick coverlet of many pieces, in which I recognise fragments of hollow stalks, bits of fine straw, and perhaps blades of grass. In front there is never any flounce of dead leaves, a troublesome piece of finery which is pretty frequent, though not always used, in the costume of the first species I described. At the back there is no long projection beyond the outer covering. Save for the indispensable collar at the neck, the whole Caterpillar is cased in sticks. There is not much variety about the thing, but, when all is said, there is a certain beauty in its stern faultlessness. There is a smaller and more simply dressed Psyche who is very common at the end of winter on the walls, as well as in the bark of gnarled old trees, whether olive-trees or elms, or indeed almost any other. His case, a modest little bundle, is hardly more than two-fifths of an inch in length. A dozen rotten straws, picked up at random and fixed close to one another in a parallel direction, represent, with the silk sheath, his whole outlay on dress. It would be difficult to clothe oneself more economically. II A DEVOTED MOTHER If I gather a number of little Psyches in April and place them in a wire bell-jar, I can find out more about them. Most of them are in the chrysalis state, waiting to be turned into Moths, but a few are still active and clamber to the top of the wire trellis. There they fix themselves by means of a little silk cushion, and both they and I must wait for weeks before anything further happens. At the end of June the male Psyche comes out of his case, no longer a Caterpillar, but a Moth. The case, or bundle of sticks, you will remember, had two openings, one in front and one at the back. The front one, which is the more regular and carefully made, is permanently closed by being fastened to the support on which the chrysalis is fixed; so the Moth, when he is hatched, is obliged to come out by the opening at the back. The Caterpillar turns round inside the case before he changes into a Moth. Though they wear but a simple pearl-grey dress and have insignificant wings, hardly larger than those of a Common Fly, these little male Moths are graceful enough. They have handsome feathery plumes for antennæ, and their wings are edged with delicate fringes. For the appearance of the female Psyche, however, little can be said.
