Linyphia (Bathyphantes) minuta.—One-eighth of an inch long, a little smaller than nebulosa. The cephalothorax is yellowish brown, darker at the edges, but without any middle line. The dark markings of the abdomen nearly cover it, so that it appears dark gray with light markings instead of light with dark markings, as in nebulosa. The legs are light brownish yellow, with dark rings on the ends and middle of the femora and tibiæ. The epigynum is folded twice, as in nebulosa [(fig. 343)]. The male palpi [(fig. 344)] have a general resemblance to those of nebulosa, but there are some distinct differences. The tarsal hook is very large and has a longer and narrower point than nebulosa. The tarsus has on the outer side near the base a conical point roughened with short ridges. This is more prominent in this species than in nebulosa. It lives in cellars and similar places often in company with nebulosa.

Linyphia (Drapetisca) socialis.—This very distinct species is marked with gray and white and is often found on the bark of trees without any web. It is a tenth to an eighth of an inch in length. The cephalothorax is white with black edges, a black spot in front under the eyes, and a black mark in the middle, from which indistinct lines radiate toward the edge. The abdomen is widest just behind the middle [(fig. 345)]. It is white, mottled with gray, and has a black stripe on each side and several pairs of black spots in the middle, connected with a middle line. The legs are white, with a gray ring at the end and middle of each joint. The spines are long on the legs and palpi [(fig. 347)]. The mandibles have an oblique dark stripe and several long hairs in front and a row of teeth in front of the claw. The epigynum [(fig. 346)] is large and extends obliquely backward away from the abdomen and curves inward again at the end. It lives all over the northern part of this country and Europe, under leaves and sometimes on trees, where it is occasionally found on the bark without any web.

Linyphia (Helophora) insignis.—An eighth of an inch long, as long as socialis, but more slender. The cephalothorax and legs are light yellow, and the abdomen gray or white, sometimes without markings and sometimes with gray stripes at the sides and two or three pairs of gray marks across the hinder half [(fig. 348)]. The cephalothorax of the male is twice as wide across the middle as at the head. The legs are without markings. The epigynum [(fig. 350)] is long and straight, extending backward close to the abdomen for half its length. The tibia of the palpal organ has a short, pointed process, extending directly outward from the side [(fig. 348)]. They live in flat webs among low plants.
