Two varieties of this mite occur in animals: (a) Psoroptes communis of the sheep and horse, and more rarely in cattle and buffalo, (b) Psoroptes cuniculi of rabbits. Chorioptes (Symbiotes) or Scale Eating Mite.--This mite lives on the surface of the skin and on scales of epithelium. In size it stands between the Sarcoptes and the Psoroptes (0.3 to 0.5 mm.). The head is short, blunt, almost round, and the legs long, provided with suckers.
