Linyphia mandibulata.—A little larger than L. communis and marginata, with the head longer and more distinct from the thorax, and the abdomen larger and flattened on the top (figs. [326, 327]). The length is about a sixth of an inch. The cephalothorax is dark orange brown, and the legs a lighter shade of the same color. The length of the legs is about as in communis, shorter than marginata and phrygiana. The abdomen is dark brown, often almost black, with several white spots, usually two across the front end and several others around the sides [(fig. 326)], sometimes forming a complete light stripe around the middle. In the males the abdomen is narrow, and the only markings are usually the two spots on the front end. The cephalothorax of the male is long and narrow; the head is extended forward, and the mandibles inclined backward toward the maxillæ. The mandibles are more than half as long as the cephalothorax and widened at the ends, with four teeth on the inner corner [(fig. 329)]. On the inner side of the mandibles, near the middle, is a large blunt tooth.

The webs are flat and near the ground, on short grass and leaves and across little hollows in the sod [(fig. 325)]. The webs are not as large as those of phrygiana, and the spider has no nest, but stands always in the web and drops suddenly when alarmed. It lives all over the eastern part of the country and resembles closely the Linyphia pusilla of Europe.

Linyphia coccinea.—About a sixth of an inch long and bright red and orange color. The size and length of legs are about the same as in communis. The legs are light orange, the cephalothorax a deeper shade of the same color, and the abdomen light red. The palpi have the ends black, and the legs are sometimes streaked with black. The hinder middle eyes are twice as large as the others and twice as far apart as the front middle pair. The space between and around the middle eyes is black. The top of the abdomen is a little flattened and extended back in a blunt black point over the spinnerets [(fig. 330)]. The male [(fig. 331)] differs little from the female except in the more slender abdomen and longer legs. The male palpi are as long as those of the female and only a little thickened at the ends. The blackened point on the end of the abdomen is less distinct in the male than the female. The web is a little concave, not as deep as that of marginata and with smaller meshes. It is made among low plants. This is a common species in the South.
