THE COMMON SPIDERS 



The female carries her cocoon in her mandibles and makes a 

 large bunch of silk in the bushes, in which the young live for 

 some time after hatching. 



Ocyale undata. — When full grown over half an inch long, the 

 thorax quarter of an inch, and the first and fourth legs an inch 

 long. The thorax is almost as wide as long, and the head not 

 much more than half as wide (fig. 215). The abdomen is long 

 and narrower than the thorax and a little pointed behind. The 

 color is a light brownish yellow, with a wide darker and browner 

 band on the middle of both thorax and abdomen. This band 

 is bordered by a white line a little curved 

 in and out toward the tail. In younger 

 spiders the color is lighter and yellower ; 

 the middle stripe has the edges more 

 undulating, and in very young ones it is 

 serrated or even broken up into spots. 

 The legs, which are plain in adults, are 

 sometimes marked with rings in the 

 young. The front end of the stripe is 

 sometimes divided into two. These 

 spiders live on bushes, without any web, 

 until they have young. In the latter 

 part of summer the females carry their 

 flat cocoons under them, holding on with 

 the mandibles. When the young are 

 about to hatch the female builds a mass 

 of web (fig. 217) three or four inches 

 through, in which she leaves the cocoon,

 two. The head is wide and less separated from the thorax
