Silvatica has the ster- num and under side of the abdomen brown, without any distinct markings. The male angulata has the thickened tibia of the second leg nearly as long as the tibia of the first leg. The male silvatica has the second tibia less thickened and a fourth shorter than the first tibia. The male angulata has a pair of long spines under the coxae of the second legs, but in silvatica these spines are so small as to be hardly visible. E. nordmanni is a smaller species, about as large as sclopctaria and strix, with light gray colors and generally distinct marking both above and below. E. corticaria is not more than half as large as silvatica and might be mistaken for the young of that species, but the colors are lighter and the rings on the legs narrower and more numerous. The epigynum of corti- caria is nearly as large as that of silvatica, and the middle appendage is often wanting as if broken off. 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. ,388. Epeira nordmanni. — Upper The legs have a dark ring at the ends and a and under markings lighter one in the middle of each joint. The ^ enlarged o J twice. 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 Please note that these images are extracted from scanned page
