Lahidocarjpus has an elongate, tapering body, annulate with many narrow ridges, and at once reminding one of the Eriophyidae, to which there is, doubtless, some affinity. Family SARCOPTID^. The itch mites ('' Sarcoptides psoriques'' of Megnin) have long been familiar through their disgusting parasitism of the human sub- ject. They often burrow within the skin of man and other mammals, and thereby produce intense itching, and a diseased condition known as scabies, mange, or more properly acariasis. The mites are very small, white, and semiglobular in shape. The body is entire, and the surface trans- versely striated and pro^^.ded with a few bristles, often short, stout, and sharp pointed. The legs (fig. 266) are short and stout, arranged in two groups. The anterior legs are usually larger than the others. The tarsi commonly terminate in a stout claw. There is generally a long pedicellate sucker, sometimes with a jointed pedicle. The claw or sucker may be absent and in its place a Fig. validus. (Original.) ^^^^ bristle. The legs often show a chitinous framework of rings, both transverse and oblique. On the front of the body is a promi- nent beak. The palpi are small, three-jointed, and appressed to the sides of the beak.
