as forward, and the black and red, fierce-eyed, stout-bodied 

 little jumping spiders (Attidse) (fig. 8i), which leap on their 

 prey. 

 The sedentary or web-weaving spiders are of various 



kinds. They 

 may be grouped 

 according to 

 their spinning 

 habits into cob- 

 web weavers 

 (Therididas), 

 small slim-leg- 

 ged spiders 

 which make the familiar unsymmetrical cobwebs of 

 houses and outbuildings; funnel-web weavers (Agalenidas) , 

 larger long-legged spiders of meadow and field which spin a 

 flat or concave horizontal web in the grass with a silken 

 tube leading down 

 to the ground; the 

 curled-thread wea- 

 vers (Dictynidae) , 

 which use in addi- 

 tion to the usual 

 lines peculiar broad 

 lines made of 

 waved or curled 

 threads in their ir- 

 regular webs made 

 in fence-corners 

 and on plants; and 

 finally orb-weavers (Epeiridae) (fig. 82), the host of variously 

 colored and patterned stout-bodied garden-spiders which 

 spin the beautiful symmetrical circular webs familiar to all. 

 If a complete uninjured orb web be examined it will be 

 found to consist of a small central hub either open or closed,
