. The common spiders of the United States. Spiders -- United States. THE I85. Fig. 431. Female Zilla atrica, en- larged four times. underneath. middle pairs than they are from each other. The mandibles are large and thickened in the middle toward the front. The epigynum and the spinnerets are both small. The color of all the species is gray, with sometimes a little yellow or pink in the lighter parts. The cephalothorax has usually, but not always, a dark border at the sides and a middle dark line that widens and becomes lighter toward the eyes. The abdomen has a wide middle stripe like Epeira, scalloped at the sides and crossed at the hinder end by two or three pairs of transverse spots. In front it is almost white or tinted with pink or yellow, and narrows almost to a point, with a much darker spot each side. The sides of the abdomen are marked with oblique dark marks that extend The sternum has a light middle stripe. Under the abdomen is a dark middle stripe, with light each side of it. The legs are pale, with nar- row gray rings at the end and middle of each joint. These three species seem to be the same as three found in Europe, — Z. atrica, Z. x-notata, and Z. montana. Atrica is found at Ipswich and Salem on the coast of Massachusetts, x-notata at Woods Hole on the south coast of Massachusetts, and montana in the White Moun- tains and Adirondacks. Wherever found they are in large numbers, atrica and x-notata living on the outside of houses, and montana in trees and rocks. »-—V- , Fig. 432.
