By removing the fine hairs and scales from the front of the butterfly's head, a small transverse lamina is observable, and its relative position determines it to be the small upper lip, once so large in the caterpillar. On either side and beneath the labrum is a very small piece of skin—the remnant of the once formidable and trenchant mandible. Beneath these is the long trunk, formed by two long and flexible structures, hollow and tubular, and at their base is a pair of small palpi. The flexible tubes are altered inflexible jaws, and the palpi are accessory organs. Below all.
