The front row of eyes is 0OO0 nearly straight, the middle pair only 33 a little the higher (fig. 33). The upper row is longer and more curved, with all the eyes about the same distance apart, the middle pair not so much separated as in incerta. The abdomen is widest behind, but not as wide as in incerta. The spinnerets are two- jointed, as in Anyphaena. The legs are long, the fourth pair longest, and are a little thicker than those of incerta. The coxae of the hind legs almost touch, and the sternum is short and nearly round (fig. 36). The labium is short and the maxillae straight, as in Any- phaena. The cephalothorax, legs, and mouth parts are light brownish yellow. The cephalo- thorax has a fine dark line on each side and two broken longitudinal stripes made up of gray marks radiating from the dorsal groove. The abdomen has two rows of gray oblique markings on a light ground. The general appearance is like a small Lycosa. It lives among leaves and short grass. There is little difference between male and female. Anyphaena incerta. — About a fifth of an inch long, light yellow, with gray markings. The cephalothorax is three-quarters as wide as long, rounded at the sides and highest in the middle. The front of the head is very low, so that the eyes nearlv 35. FlGS- 33, 34, 35» 36.
