THE COMMON SPIDERS 



with several turns of the wide temporary spiral still in them 

 (fig. 495). Sometimes there are zigzag lines of loose silk across 



the center or in a middle spiral, 

 and when the eggs are laid the 

 long cocoons are fastened in a 

 line of silk across the web (fig. 

 497). When this is done the 

 center of the radii of the web 

 is usually at the upper part, 

 instead of in the middle, and 

 the whole web is one-sided. 

 It is found all over the coun- 

 try, usually in shady woods, 

 in bushes, or in the lower

 Hyptiotes cavatus. — This peculiar spider resem- ^ 

 bles in shape and color the end of one of the U 

 dead pine branches among which it 

 lives. It is a sixth of an inch long. 

 The cephalothorax is as wide as long, 

 highest in the middle, and hollowed 

 behind under the abdomen. The abdo- 

 men is oval, thickest behind, and flat- 

 tened in front, and has on the back 

 four pairs of slight elevations, on which 

 are a few stiff hairs (fig. 498). The 

 legs are short and thickest in the mid- 

 dle, tapering toward the claws. The 

 hind metatarsi are curved in at the 

 calamistrum (fig. 499). The eyes are arranged as in Uioborus, 

 but are farther apart and farther back on the cephalothorax.
