Superfamily Argiopoidea 



(Fig. 6 1 1). The third and fourth pairs of legs are as long as or 

 nearly as long as the first and second pairs. The hairs of the 



body are pubescent or plumose 



(Fig. 6 1 2), and prone, not erect. 



And the upper margin of the 



furrow of the chelicerae is 



armed with one or two teeth. 

 These spiders are very 



active and pursue their prey 



with great rapidity. Most of 



the species live on plants; 



when at rest, the body is 



closely applied to the sup- 

 porting object, with the legs 



stretched out separately or in
