MITES 1013 and with soft, often velvety skins, frequently of scarlet and otherbrilliant colours. The large Trombidium Jiolosericum is a well-knownmicroscopical object. The Tetranychi are usually included in thisfamily ; they are, however, rather doubtful members ; they are the red-spiders of our greenhouses, much dreaded by horticulturists. Eachfoot is provided with about four singular hairs with round knobs atthe end. Bryobia is an allied genus found in great numbers on ivy&c. in gardens and is a beautiful object. The hexapod larva? of severalspecies of Trombidium often attach themselves temporarily to the skinof animals, including man, and produce intolerable itching. They weresupposed by the earlier Acarologists to be all one species, and tobe adult, and to form a distinct family; they were called Leptusautwmnalis, and are known in England as the harvest-bug, andin France as the rouget. The Bdellidce are also included in thisfamily ; some authors also include the Chey
