$Epeira nordmanni.$--This is a little smaller and a little longer legged than _cinerea_ and _angulata_. The abdomen is longer than in those species and has two similar humps in front (fig. 387). The female is not more than half an inch long. The colors are white and gray or black. The cephalothorax is light gray, darkest at the sides, but without stripes. The legs have a dark ring at the ends and a lighter one in the middle of each joint. The abdomen has a distinct middle stripe on the hinder half. In front there is an indistinct dark area extending to the top of the humps and, in the middle, inclosing a bright, long, white spot, with a round spot on each side sometimes united with it. The sternum is dark brown, without any stripe. The under side of the abdomen has a middle dark area in which are four yellow spots, two just behind the respiratory openings and two farther back, halfway to the spinnerets. [Illustration: FIGS. 389, 390.--389, Epeira angulata. 390, Epeira silvatica. Both enlarged twice.] $Epeira angulata$ and $silvatica.$--These spiders, which are perhaps varieties of the same species, live usually among large trees and grow to over half an inch in length. The abdomen has two slight humps on the front. The colors are dark, like the bark of trees. The cephalothorax is dark brown, with traces of darker lines in the middle and at its sides. The legs are brown, with darker rings at the ends of the joints and less distinct rings in the middle. The abdomen has a bright yellow spot in front. The middle stripe is darker brown than the rest and has a scalloped edge marked by a dark and light line, which may be entire or broken into lines of spots. The under side of the abdomen is black or brown, with sometimes several yellow spots. The sternum is uniform brown in _silvatica_ and has a yellow middle stripe in _angulata_. The males are colored like the females and are about half as large, with the legs longer, especially the front pairs. The tibia of the second legs is twice as thick as that of the first pair, a little bent, with the spines stouter and more numerous than in the female. In the male of the _angulata_ variety the tibia of the second pair is nearly as long as that of the first, but in _silvatica_ it is distinctly shorter. On the under side of the coxæ of the second legs is a conical spine, which is longest in the _angulata_ variety. The epigynum is small for so large a spider and has a long slender finger in the middle. These spiders are found singly or in small numbers, usually in the woods, sometimes in webs hung between trees high above the ground. [Illustration: FIG. 391.
