Superfamily Argiopoidea 



on the hinder half. The male measures one third inch in length; 

 the female a little more. This is a variable species; Fig. 731, d 

 represents the epigynum of the typical form and Fig. 73 1 , ^ that 

 of the variety P. modica brunnea. Figure 732, b represents the 

 palpus of P. modica brunnea. 



This is a Northern species whose range extends from Green- 

 land south into the northern part of the United States from New 

 England to Oregon. 



Pardosa emertoni (P. em-er-to'ni). — The cephalothorax is 

 yellow with two brown stripes which unite and become black 

 between the middle eyes and there is a fine black line near the 

 edge of the thorax on each side. The abdomen has a light middle 

 band not much widened in front, where it includes a light stripe 

 with dark brown edges, which tapers to a point about the middle 

 of the abdomen. The hinder part of the middle stripe is indis- 

 tinctly divided into four or five segments; at the sides of the middle 

 stripe the abdomen is dark brown or black in small irregular spots 

 and becomes gradually lighter toward the sides. The epigynum 

 is represented in Fig. 731,/. The length of the body is about one 

 fourth inch. 



This is a Northern species whose range extends south to the 

 District of Columbia. It was originally described by Emerton 

 under the name Pardosa pallida; but as the name pallida was pre- 

 occupied, Chamberlin has proposed the name emertoni for the 

 species. 



Family OXYOPID^E (Ox-y-op'i-dse) 



The Lynx-spiders 



The lynx-spiders are so called because some species chase 

 their prey with great rapidity over herbage and the foliage of 

 trees and shrubs; they even jump from branch to branch like the 

 attids; but other species lie in wait near flowers and spring upon 

 insects that visit the flowers. 



The legs are long, with three tarsal claws but without scopulx; 

 the trochanters are not notched as in the two preceding families 

 or but slightly so. The eyes are eight in number, dark in colour, 

 and unequal in size; the anterior median being very small. The 

 anterior row of eyes is strongly recurved; the posterior row, pro- 

 curved; so that there may appear to be four rows of eyes of two 

 each (Fig. 733). The abdomen tapers to a point behind.
