Pediculus. Three species of lice are met with in the human subject - the Pediculus capitis or head-louse, the Pediculus corporis or body-louse. and the Pediculus pubis. The first-named variety sometimes infests the heads of children, causing much irritation. The female louse deposits the ova or nits upon the hairs, where they are seen as minute semi-transparent bodies. The body-louse deposits its ova on the clothes, and its presence brings about a papular eruption on the skin. The condition in which the body is infested by lice is called phthiriasis.
