. Cassell's natural history. Animals; Animal behavior. ir-shaped l)0(ly, iijion wliich two pai-ts may be recognised, a small anterior and inferior iig the eyes, the oi-giur; of the mouth, and the first two pairs of legs, and a larger posterior portion, on the under surface of which, at some distance from the others, the third and fourth pairs of legs are situated. The whole Mite is of a bright scarlet colour, and the larger hinder part shows a beautiful velvety texture. This Mite may l)e often seen running about upon the ground, in moss upon the roots of trees, itc., and it is exceedingly rapid in its movements. In a young stage, it passes a certain period as a parasite upon the long-legged Harvest Spiders {Phalanyiurit), usually selecting the females, and attaching itself beliind the hinder coxse, where it is out of reach. In this situation it remains, although capable of some amount of movement, and its six legs advance more and more towards the front as the animal grows. When. iioLcsERicEUM. detached from the Harvest Spider, it conceals itself in the ground, and becomes an oval nymph, within the skin of wliich the eight-limbed perfect Mite may be watched in process of formation. The change takes about three weeks. Other species of the group attach themselves to insects of various kinds to undergo this nymphal change, and, as all of them attack and destroy Aphides, and other minute insects, they must be regarded to a certain extent as our friends. FAMILY III.—HYDRACHNID^, OR WATER MITES. These creatures may be regarded as aquatic representatives of the Trombidia, as they resemljlo these in many characters. They have usually a more globose form of body, and there is no trace o£ its division into two parts; the chelicerie are similar; the palpi terminate in hooks or bristles; and the legs, which generally increase in length from the first to the fourth pair, are strong and fringed, and terminated by a pair of claws. They have two ocelli on the fore part of the bo
