The tibia of the male palpus has a large inferior process slight!}^ 

 bent inward at the end. The outer process is longer and the slender 

 tip is on the inner side and s-shaped. Fig. "Id. The tube of the 

 palpal oi'gan is stout and has in the middle a thick portion, rough- 

 ened like a file. The end of the tube is straight, not s})iral as in 

 C de2)ressa.

The female of this species is the largest and best known of the 

 genus. It is 8 or 10""" long and milk white, with sometimes a light 

 crimson marking on each side of the abdomen. PI. xxx, fig. 1. 

 The cephalothorax is wide and high in front, the distance between 

 the upper lateral eyes being twice their height. Fig. \b. The sides 

 of the cephalothorax are very light yellow or brownish, the dark 

 color being most distinct in young spiders. The dark markings also 

 extend between the eyes and around the sides of the head, but the 

 front of the head has a white mark that widens below over the 

 mandibles and above under the eyes and around the eyes of the 

 upper row. This marking of the front of the head, PI. xxx, 

 fig. \b, distinguishes this species from aleatoria. 



The legs are white with light brown on the upper side of the first 

 and second ; or even this is absent in some individuals. 



The epigynum has a deep rounded notch in the middle, the corners 

 of which are prolonged backward over the spermathecse. Each side 

 of the large notch are two small ones. PI. xxx, fig. \g. 



The male is only 3 or 4"'"^ long, with the front legs about twice 

 the length of the body. The males are strongly marked with dark 

 reddish brown on a light ground. The cephalothorax is dark at the 

 sides, while the front of the head around the eyes is white, as in the 

 female. The abdomen has a dark stripe at the sides extending, 

 sometimes, its whole length, or in other individuals not more than 

 half as far. In the middle of the abdomen are two parallel dark 

 marks or lines of spots, figs, id, le. The first and second legs have 

 the femur dark brown, the patella dark on the outer half. The tibia 

 dark at both ends, and the tarsus and metatarsus on the outer half. 

 The palpi are light with the palpal organ brown. The third and 

 fourth legs are light. 



The male palpi are small. The tarsi are short and nearly as wide 

 as long. The tibial jirocess is smaller than in the other species and
