See pediculus humanus. The head louse; a form of pediculus inhabiting the hairy scalp. It varies in length from 2/3 to 1 1/2 mm., and has an elongated, ovalish body with an acorn-shaped head, provided with two antennae, prominent eyes, and a suctorial mouth. Attached to the thorax are six legs armed with claws and hairs. Its color is commonly grayish or ashy, but is said to vary according to the color of its host, in Eskimos appearing white, in negroes black, and in Chinese yellowish brown. The ova ("nits") are pyriform or oval in shape, and are firmly attached to the hairs. It may produce impetigo, by its bite.
