 SILK SPIDERS, TUBE or BAG WEAVERS.—DRASS/DZ.

This family resembles short-legged Lycoside in shape. Some seem homeless, wandering about at night time, others spin tubes or bags under stones, logs or curled-up leaves, which they seldom leave in day time. Their wintering bag is made of several coats of the finest, whitest silk, and is beautifully soft and warm. American Drassid@ have never been well studied. About fifty kinds have been described in European and American publications, some perhaps twice under different names. Hentz describes most kinds under the names of Herpyllus and Clubiona. Other writers divide the family into Drasside and Clubionide, of which the first contains the dark colored kinds which live on the ground, and the latter the mostly light colored kinds which live on shrubs and plants. They are so nearly related that it seems better to keep them in one family and to divide the same into sub-families.
