. A manual for the study of insects. Insects. INSECTS AND THEIR NEAR RELATIVES. 41 spiders frequently attract especial attention by dragging after them a large gray ball (Fig. 47) ; this is the egg-sac, which the female carries about with her attached to her spinnerets. These spiders run swiftly; and as they depend. Fig. 47.—Lycosa and eg-gf-sac. on the use of their legs for the capture of their prey, they are well termed Running Spiders. These spiders resemble in general appearance and in habits the Tarantulas of the South and the West. But none of our species attain the great size of some of the Tarantulas, and in the Running Spiders the claw of the mandibles moves horizontally instead of vertically. In this family the body is hairy and usually much longer than broad. The eyes differ markedly in size, and are arranged in three or four rows. The larger eyes are not in the front row. The legs are rather long and quite stout. Like the Tarantulas, some of the Running Spiders build tubular nests in the ground, which they line with silk. Some- times the entrance to these nests is concealed by small sticks and leaves, and sometimes the spi- der builds a regular turret over the entrance of its tube (Fig. 48). These nests are used merely as retreats, the spiders wandering forth in search of their prey.
