And what does the insect that has conceived the ambition of later planting a spear upon its chine propose to make of its projected work? At least as an adjunct of masculine finery, the thing is in fashion among various foreign Scarabs that feed themselves and their grubs on vegetable matters in a state of decomposition. These giants among the wing-cased tribe delight in associating their placid corpulence with halberds terrible to gaze upon. Look at this one—Dynastes Hercules his name—an inmate of the rotten tree-stumps under the torrid West-Indian skies. The peaceable colossus well deserves his name: he measures three inches long. Of what service can the threatening rapier of the corselet and the toothed lifting-jack of the forehead be to him, unless it be to make him look grand in the presence of his female, herself deprived of these extravagances? Perhaps also they are of use to him in certain works, even as the trident helps Minotaurus in crumbling the pellets and carting the rubbish. Implements of which we do not know the use always strike us as singular. Having never associated with the West-Indian Hercules, I must content myself with suspicions touching the purpose of his fearsome equipment. Well, one of the subjects in my voleries would achieve a similar savage finery if he persisted in his attempts. I speak of Onthophagus Vacca. His nymph has on its forehead a thick horn, one only, bent backward; on its corselet it possesses a like horn, jutting forward. The two, approaching their tips, look like a sort of pincers. What does the insect lack in order to acquire, on a smaller scale, the eccentric ornament of the West-Indian Scarab? It lacks perseverance. It matures the appendage of the forehead and allows that of the corselet to perish atrophied. It succeeds no better than Onthophagus Taurus in its attempt to grow a pointed stake upon its chine; it loses a glorious opportunity of making itself fine for the wedding and terrible in battle. The others are no more successful. I bring up six different species. All, in the chrysalis state, possess the thoracic horn and the eight-pointed ventral coronet; not one benefits by these advantages, which disappear altogether when the adult splits its case. My near neighbourhood numbers a dozen species of Onthophagi; the world contains some hundreds. All, natives and foreigners, have the same general structure; all most probably possess the dorsal appendage at an early age; and none of them, in spite of the variety of the climate, torrid in one place, moderate in another, has succeeded in hardening it into a permanent horn.
