Superfamily Argiopoidea 



I have not seen this sex of the species. The above account 

 is drawn from Keyserling's original description of Xysticus emer- 

 toni, which is now regarded as the female of the species the male 

 of which he had described on an earlier page of his Spinnen 

 Amerikas as Xysticus elegans. 



The male of X. elegans (Fig. 591) measures about one fourth 

 inch in length. It presents a very striking appearance, due to 

 its strongly contrasting colours. The cephalothorax is reddish 

 brown, streaked and flecked with yellow, and with a broad, light, 

 median, longitudinal band, which is bordered on each side with 

 a yellow line; these two lines come together behind in a point; 

 and there is a yellow transverse band between the two rows of 

 eyes. The abdomen is brownish white dotted with brown 

 points, and with four pairs of large brown patches as shown in the 

 figure. The unexpanded palpus is represented in Fig. 592. 



This species is widely distributed in the Eastern States. 



Xysticus ferox (X. fe'rox).— This species is of medium size, 

 the female (Fig. 593, a) measuring about one fourth inch in 

 length, and the male (Fig. 593, b) one fifth inch. The cephalo- 

 thorax is yellowish in the middle and reddish brown on the sides, 

 marked with a net-work of dark lines; at the posterior end there is 

 a small median black spot and a larger one on each side. The 

 abdomen is brownish gray above and smoky white on the sides; 

 there are several small, black spots on the basal part above, 

 and three pairs of transverse black bars bordered in front with 

 white on the hind part. The form of the epigynum is represented 

 in Fig. 594 and that of the male palpus in Figs. 569 and 570 

 on page 522. 



Xysticus formosus (X. for-mo'sus). — This is a beautiful 

 brown and white species, which can be easily recognized by 

 its characteristic markings (Fig. 595). The female measures 

 one fourth inch in length; the male, one fifth. It is found in the 

 Northern States. 



Xysticus gulosus (X. gu-lo'sus). — This is a large species, 

 the female (Fig. 596) measuring from one fourth to one third 

 inch in length. It is grayish brown in colour and presents a very 

 distinctively characteristic appearance from the fact that the 

 white ground is largely covered with minute brown specks. 

 The median lighter area of the cephalothorax, and transverse 

 light bands on the hind part of the abdomen are more or less
