Hahnia bimaculata.—The Hahnias resemble Tegenaria, but are much smaller and have the spinnerets extended in a line across the under side of the abdomen [(fig. 251)]. Hahnia bimaculata is about one-eighth of an inch long, with the abdomen large and oval, widest behind, as it is in Cælotes [(fig. 250)]. The cephalothorax is bright orange brown, and the legs and abdomen pale yellowish with gray markings. The legs are ringed with gray, the longer joints having two rings, and the abdomen has a pattern of light yellow and gray spots. The spinnerets are all long and in a nearly straight line, half as long as the width of the abdomen. The outer or upper pair are half as long as the abdomen, and the two joints are nearly of equal length. The tracheal opening is in the middle of the abdomen, nearer the epigynum than the spinnerets. The sternum is as wide as long, widest opposite the second legs. The maxillæ are straight in front and have a slight projection at the outer corners, where there are two or three stiff hairs. In some other species there is a longer process at these corners.

This spider is common in winter under stones and under leaves. In summer it makes webs close to the ground, among short and thin grass and moss.

Hahnia cinerea.—About a twelfth of an inch long; much smaller than bimaculata [(fig. 251)]. The color is dark gray, the cephalothorax and legs brownish, and the legs a little lighter at the ends of the joints. The abdomen has a row of angular light spots in the middle. The spinnerets are in not quite as straight a line as in bimaculata, the outer pair being a little higher and farther behind the next. The tracheal opening is not as far forward as in bimaculata, being nearer the spinnerets than the epigynum. The male palpi have the appendages of patella and tibia longer than in bimaculata, and softer and more curved. They are found under stones and leaves.
