This arrangement enables the larvae to use much force and tearing power when they are perforating trees, to which they do, in the tropics, a great deal of harm. Fortunately, however, our trees do not suffer from them. The beetles of the genus ChalcopJwra are amongst the largest of. Cluikopliora Alariana. the family; and the species MarianUy whose metamorphoses are illustrated in the engraving on page 324, is a prettily-sculptured and bronzed beetle, which is common in the pine forests of the south of France, Italy, and Germany. Its larva hollows out large galleries and holes in the trunks of the trees. In the same engraving the larva which has done part of this mis- chief is shown in its gallery, and its small head and enormously developed first thoracic segment may be noticed, the rest of the body being rather slender. It undergoes the metamorphoses in one of the galleries, and in one of them a pupa observed, whose structures foreshadow those of the adult form very distinctly. The Longicorn Beetles, or the Goat Beetles, as they are sometimes called, on account of their long, cylindrical antennae, V 2.
