Superfamily Argiopoidea 



straight or slightly procurved line, with the median eyes sub- 

 contiguous. The abdomen is long and narrow. The first legs 

 in the males are much longer than the others. 



Two species are widely distributed in the eastern half of the 

 United States; a third, a South American species, Wala grenada, 

 has been found by Mr. Banks in southern Florida. 



IVala palmarum (W. pal-ma'rum).— The male is reddish, 

 with a broad white band on the sides extending the whole length 

 of the body (Fig. 752). The clypeus is marked with white hairs 

 and yellow scales in the eye-region; and there are dark spots at 

 the base of the eyes. The front legs are dark, all others are white. 

 In the female the cephalothorax is reddish, and the eyes are on 

 dark spots. The legs and palpi are white. The abdomen is 

 light, with large triangular spots in the centre and small dark spots 

 at the sides. The length of the body is about one fifth inch. 



This species is common on trees and bushes throughout the 

 summer months in the Eastern United States. 



IVala mitrata (W. mi-tra'ta). — This species closely resembles 

 the preceding one; but the legs are all white in both sexes, and 

 the chelicerse of the male are white and not long and horizontal 

 as in IV. palmarum. The distribution of the species is similar 

 to that of IV . palmarum. 



Genus PHIDIPPUS (Phi-dip'pus) 



The cephalothorax is high, heavy, and convex; the first 

 legs are heavy and very hairy, and are often fringed. This 

 genus includes spiders which are above the medium size, and is 

 represented by thirty-eight known species in our fauna. The 

 following are those most likely to be taken in the more thickly 

 settled portions of our country. These can be separated by the 

 following table. A table to all of our species is given by the 

 Peckhams ('09), from which this is compiled. 



A. Abdomen red or marked with red. 

 B. Males. 



C. Cephalothorax red above. P. 682. P. whitmanii 



CC. Cephalothorax black above. 



D. Abdomen black spotted with red. P. 683. 



P. insolens (in part)
