The webs them- selves are of various kinds, and constructed with more or less skill; Fig. Tcgnearia domettica ^ they are either delicate and thin and formed of irregularly arranged threads, or they are of a felt-like quality and extended horizontally or again, they may have the form of vertically placed wheel-shaped nets; in this case they consist of concentric and radial threads, which are arranged with wonderful regulai-ity, the radial threads meeting in a central point. Tubular or funnel-shaped hiding-places for the spider are often found near the webs.
