In other instances (such as the Moths and Butterflies) we find that the parts of the mature insect exist in the same way, in an imperfectly developed state, but that tliey are closely a|>plied to the body within ] their proper sheaths, and that a continuous case of a more or less horny texture envelops the whole, and renders all the parts incapable of motion, except that the abdomen can generally bend more or less. This outer case follows all the inequalities of the surface produced by the limbs, antenniB, wings, iL-c, which can thus be distinguished as easily as in the preceding forms. An insect in this condition is commonly denominated a chrysalis ; it is, of necessity, incapable of moving about or taking nourishment. ' As these insects generally pass a considerable time in this helpless and inacti^â e condition, during which the parts of the perfect insects are being brought to maturity within them, the larvse, before undergoing the change above described, usually select some suitable shelter for the purpose. Many burrow into the ground, and pass the interval of repose in a chamber which secures them from the attacks of enemies and the inclemency of the weather; others .seek concealment in slieltered corners, or in the crevices of the bark of trees ; others again content themselves with such protection as they can get by adhering closely to the stems or branches, or the under side of the leaves of the plants on which they feed; and not a few, even of those which take up their abode in sheltered situations, spin for themselve
