Superfamily Argiopoidea 



female agrees with that of T. straminea in that the endite of the 

 pedipalp reaches the tip of the claw of the chelicerae; but dif- 

 fers in having the outer side of the chelicera not so obviously 

 concave. This is a widely distributed but uncommon species. 

 Tetragnatha pallidula (T. pal-lid'u-la). — This is a widely 

 distributed species in the East but it is not common. It can be 

 easily recognized by the characters given in the table above. 



Genus EUCTA (Euc'ta) 



This genus is very closely allied to Tetragnatha; but the 

 members of it are easily recognized by the fact that the tip of the 

 abdomen projects a considerable distance beyond the spinnerets 

 (Fig. 428). The abdomen is very long and slender. 



I have found by observing living individuals that the tail of 

 these spiders can be extended and contracted a considerable

distance, so that the length of the abdomen may vary greatly 

 from moment to moment. 



1 have not seen the web of Euda and can find no description 

 of it; it probably resembles that of Tetragnatha. The spiders of 

 this genus that I have collected were swept from aquatic plants 

 projecting from the water of marshes. I have collected them both 

 in New York and in Mississippi. 



Eucta caudata (E. cau-da'ta). — This species resembles very 



closely Tetragnatha straminea except in the shape of the abdomen, 



which is longer and has a tail about one fourth of the length of 



the abdomen extending backward beyond the spinnerets (Fig. 



428). 



Subfamily METING (Me-ti'nae) 



The Met ids (Me'tids) 



The metids are closely allied to the tetragnathids and by some 

 writers are classed in the same subfamily. The two subfamilies agree
