Its congener, U. mamme-atus, he found dwelling most frequently in cavities, among large logs, andin hollow trunks of trees. ^ Emerton found Plumipes between loose stonesor low bushes in New England. Mrs. Peckham almost invariably foundthis species buildmg in dead branches, six out of seven being thus located.^She gives an apt abstract of its habits. In form and color it resemblesa scrap of bark; its body is truncated and diversified with small humps,while its first legs are very uneven, bearing heavy fringes of hair on thetibia, and having tlie terminal joints slender. Its color is a soft wood. Flii. 160. Orbweb of Uloborus, spun in the opening of a hollow stump. brown or gray, mottled with white. It lias the habit of hanging motion-less in the web for hours at a time, swaying in the wind like an inani-mate object. The strands,of its web are rough and inelastic, so that theyare frequently broken, and this gives it the appearance of one of thosedilapidated and deserted webs in which bits of windblown rubbish arefreciuently entangled. Baron Walckenaer says that the closely related European species, Ulo-borus Walckenaerius Duges, generally spins its horizontal snare betweenthe stems of rushes in dry and warm places, which resembles that ofEpeira in form, but of looser tissue.* Hahn found the species in the 1 Phillyra mammeata.
