. Animal parasites and human disease. Medical parasitology; Insects as carriers of disease. Fig. 142, Human itch mite, Sarcoptes scabiei; 9, female; $, male. 100. (Partly after Banks.) X about burrow beneath the skin and lay eggs in the galleries which they make. They are nearly round and the cuticle is delicately sculptured with numerous wavy parallel lines, pierced here and there by stiff projecting bristles or hairs. There are no eyes or tracheae. The cone-shaped mouthparts are covered over by the shieldlike upper lip. The legs are short and stumpy and are provided with sucker-like organs, called ambulacra, at their tips. In the female the two posterior pairs of legs terminate in a simple long bristle, whereas in the male only the third pair of legs terminates in bristles. The human itch mite, Sarcoptes scabiei, is only slightly distinguishable from the itch mites which cause scabies and mange in many of our domesticated animals. Each infected species of mammal has its own variety of itch.
