small spots all over the body. The middle of the cephalotliorax is 

 as usual light colored with a few brown markings in the middle and 

 toward the eyes. The sides of the cephalothorax are darker with 

 irregular brownish lines. The abdomen has three or four pairs of 

 indistinct brown spots, in front of which and on the front of the 

 abdomen are irregular small Avhite spots. The legs are marked in 

 the same way with irregular light and dark spots, the first and 

 second pairs a little darker than the others. PI. xxviii, figs. 4, 4a. 



In the males the first and second legs are very long and slender, 

 the second twice as long as the third pair. The markings are a little 

 brighter and more distinct than in the female. The under process 

 of the tibia of the male palpus is curved and turned outward at the 

 end as in gulosus. The processes of the bulb ai'e long and the ante- 

 rior one has a complicated twist at the end. Figs. 4c, Ad, 4e. 



The epigynum has a large oval opening, widest behind, in which 

 are two smaller openings divided by a narrow ridge, fig. 46.

 of the female are white or yellowish with a few black hairs and 

 small spots around the ends of the femora. The cephalothorax is 

 yellowish brown with a line of black marks each side ending in a

 light behind and darker toward the front and middle of the head, 

 PI. XXIX, fig. 1, and the area between tlie eyes is white. The 

 abdomen is white with two small black spots in front and several 

 lines of black spots broken in the middle across the hinder half.

 The markings of the cephalothorax are like those of the female, but 

 darker. The femora of the first and second legs are dark brown 

 and the rest of the legs dull yellow. The tarsus of the male palpus 

 is Avhite and the rest dark. The abdomen has very dark markings, 

 those of the hinder half usually running entirely across, with white
