. The common spiders of the United States. Spiders. THE EPEIRID/E 197 a zigzag band (fig. 448) of white silk up and down across the middle, and a round thick spot where the spider stands. The inner spiral of these webs is very large, covering a quarter of their diameter (fig. 452). The outer spiral comes very near it, but the spider sometimes passes through the narrow space between them from one side of the web to the other. The web is usually a little inclined, and on one or both sides sometimes has a screen of irregular threads two or three inches distant from it (fig. 453), but these are often absent. These spiders have no nest and stand all the time in the center of the web (fig. 448). Sometimes the spider draws away the grass and leaves so as to make an oval opening large enough for the web (fig. 453). In September the eggs are laid in large pear- shaped cocoons with a brown paper- like surface, hung by threads among the grass and bushes (fig. 454). The young hatch during the winter and remain in the cocoon until May. The adult spiders disappear in October and probably all die before winter. Argiope transversa. — This species is a little smaller than riparia. It lives in the same places and matures a little later, about September i. The abdomen is more pointed than that of riparia (fig. 455). The ground color is white or light yellow, and is crossed by a great number of black transverse lines, which are sometimes obscured, especially in. Fig. 454.
