The antennae arise from either side of the snout, are bent for- ward, or 'elbowed,' and end in a club. The larvae are soft, foot- less, wrinkled, whitish grubs, with brown head, often thinly covered with short, bristly hair, and live mostly in fruits, nuts, or seeds, or under bark, though a few live on vegetation externally. All of the families attack plants and are therefore more or less injurious, some of our most troublesome pests being found in this series. Though there are common ex- amples of several other families, only three families are suffi- ciently numerous to warrant mention. The curculios (Curculionidae) are the most typical as well as the FIG. 250. Head and mouth-parts of the boll weevil larva largest family of the suborder,
