The adult female is 5"^"^ long, with the <5ephalothorax 2""" wide. 

 It is less flattened than most species and has the cephalothorax 

 rounded up in the middle, where it is much higher than the eyes. 

 PI. XXIX, fig. 5. The cephalothorax is dark brown, almost black, 

 with a lighter line in the middle and a white line each side near the 

 edge. The legs ai'e colored in the same way, but the thin parts 

 between the joints are white. The tarsi of all the legs are lighter 

 than' the rest. At the base of the first and second femora, in front, 

 are white spots, and the third and fourth legs have white longitud- 

 inal stripes. The under side of the cephalothorax and legs are of 

 the same color, with white joints. The abdomen is light gray with 

 indistinct lighter lines at the sides and small light spots in the 

 middle. PI. xxix, fig. 5. The epigynum has a small opening, with 

 two wide anterior and two sharp posterior projections from its 

 edges. Fig. oh. 



Two young specimens less than half as large, liave all the dark

Oxyptila Simon, 1864. 

 This genus differs little from JCysticus. The cephalothorax is 

 flatter in the middle and the head narrower. The middle eyes of 

 both rows are nearer together so that they form a rectangle longer 

 than wide. The middle eyes of the front row and usually of both 

 rows are farther forward than in Xysticus, so that both rows of eyes 

 are more curved. There is less difference between the length of the 

 front and hind legs in the males than in JCysticus. The dark mark- 

 ings of the thorax often approach each other behind, as in our species.
