A natural history of the orbweaving spiders of the United States, with special regard to their industry and habits CUbiodiversity1121211-9742 Year: 1889 ( ARGIOPE AND IIER RIBBONED ORB.' 107 i Central decorations on orbs of Argyraspis. more elaborate than that shown at Fig. 98, having well defined radii and a spiral system at least in the lower part; but I have never seen one that extended beyond the bounds of what in a perfect orb is the central space. The zigzag ribbon is present, but scant and ill defined. The habits of the male and another drawing of his snare will be found in a subsequent chapter. The following are measurements of several webs of Cophinaria : No. 1. Radii, 35; notched spirals, 13; beaded spirals, 24. Specimen half grown. No. 2. Radii, 26; notched spirals, 13; beaded spirals, not counted. No. 3. Radii, 30; beaded spirals, 16 above the hub, 31 below; the orb 12 inches in length, 10 inches wide. Shield and ribbon 5 inch- es long. A strong fender placed three inches from tlie spider. Eight notched s[)irals partly covered by the shield. The ribbon en- tirely traverses the shield space. No. 4. Radii, 35, 18 on one side of the ribbon, 17 on the other, including the radii inclosing the rib- bon. Notched spirals 13, nearly filling the open space. Beaded spirals 24. Width of orb, 8 inches. Zigzag ribbon, 3 inches, including the shield, which is about five-eighths inch. II. The Banded Argiope (A. argyraspis) is an abundant species, at least in Pennsylvania and the adjacent States to the south and east. The female is generally somewhat shorter in body length than the Basket Ar- . • giope, ai\d otherwise smaller. The abdomen tapers gradually from the middle part toward the apex. The sjudcr is of a gen- eral whitish gray color; her abdomen is covered above witli a bright silver gloss, and is crossed longitudinally by two pretty yellow bands, an
