Xysticus limbatus.—This is one of the largest species, the females reaching a length of a third to half an inch (figs. [89, 90]). The thorax is one-eighth of an inch wide and nearly as long. The abdomen is a little wider at the hinder end. The legs are short, the longest about half an inch in length. The whole body is hairy. The color is brown, the markings dark on a light ground, best shown by the figures. The middle of the head and thorax is more fully covered by the dark markings than in other species. There is great variation in the color, and young spiders are usually lighter than adults. Adult males and females in June and July.
Xysticus gulosus.—This is a very distinct species and less variable in markings than limbatus and stomachosus. The color is brown or gray, with indistinct darker markings (figs. [91, 92]). The whole body is covered with fine brown spots and has at the hinder end of the thorax and on the legs traces of the same markings that show more distinctly in stomachosus. There are a few transverse dark lines on the hinder half of the abdomen and less distinct longitudinal lines at the sides of the front half.
The male is a fourth smaller than the female, with a smaller abdomen and more slender legs, but the same colors and markings. It is usually found under bark or stones which it closely resembles in color.
Xysticus nervosus.—This is a pale species, the females of which are nearly as large as limbatus. The color is light brownish yellow, with small spots of lighter and darker color scattered all over the body, and there are traces of the markings which are more distinct in other species (figs. [93, 94]). On the hinder half of the abdomen are three or four pairs of very indistinct transverse markings. The legs are marked with irregular dark and light spots, without any distinct rings or markings, and the first and second pairs are darker than the others. In the male the first and second legs are twice as long as the third and longer and more slender than in the other species. It lives on fences and under bark.
