THE COMMON SPIDERS 



are white. The third and fourth legs are light colored, with a 

 little brown at the ends of the joints. The second legs are 

 darker, and the first pair are almost black, except at the ends. 

 The males are colored like the females, but have the abdomen 

 not much larger than the cephalothorax (fig. 298), and the hump 

 rounded. This is a southern species and is said to live among 

 the outer threads of webs of large Epeiridae. It does, however, 

 make webs of its own, and I have seen the adults of both sexes 

 at Charleston, S.C., in these webs away from any other spiders.

Argyrodes fictilium. — In this species the pointed hump on the 

 abdomen is much more elongated than in trigonum, in some 

 spiders to eight or nine times the length of the cephalothorax 

 (fig. 300). The tip is rounded in young specimens and sharp 

 pointed in the larger ones. The front of the head is more 

 inclined than that of trigorunn (fig. 301). The colors are light 

 yellow and silvery white, with three darker lines on the cephalo- 

 thorax and a faint middle line on the abdomen. The legs are 

 very slender and long in proportion to the long abdomen. 

 Found rarely from New England to Alabama.
