(Re-drawn from Westwood [Griffiths' Animal Kingdom].) elongate cylindrical jointed creatures with scaly heads, or short and wrinkled gi-ubs like the wood borers; others quite slug-like feed upon the surface of the foliage: and a few are clothed with fine hairs. In the pupal state, for all beetles undergo a complete meta- morphosis, tliej are inactive, mummy-like creatures showing the outlines of the future beetle, with the wings, antennae, and legs closely folded down, and the whole enveloped in a thin membrane. Some form regular cocoons from the.
