1. Biology of an eriophyid mite Eriophyes kuko KISHIDA, a parasite of Lycium chinense MILLER, was studied both in field and in laboratory in 1967 and 1968. The female was redescribed. The male is unknown. 2. Female mites passed through the following stages in their development: egg, protonymph, nymphochrysalis, deutonymph, teleiochrysalis, and adult. The time required for mites to develop from egg to adult was 7. 5 days on an average in June. 3. It was observed that the galls were significantly densely distributed along the veins of leaves. This seems to suggest a close relationship between the mite and the leaf sap. 4. The immature adult mites which emerged from the galls of a grown-up leaf crawled on it or were carried by the wind to arrive at the stem, and they climbed the stem to the top. There they found young leaves and fixed their bodies along the leaf veins. Next, they began to sip the leaf sap and then penetrated into the leaf tissue through the sipping pores. The leaf epidermal area infected with each mite gradually swelled up to a gall. Thus the animals grew up into adults within the gall and laid their eggs there.
