In the classification of this family I have followed the arrange 

 raent and names used by Simon in Arachnides de France, except that 

 I have included Oxyopes, as was done by older writers. The family 

 includes three sub-families, Lycosinae, including Lycosa, Pirata, Par- 

 dosa and Aulonia ; Dolomedinre, including Dolomedes and Ocyale ; 

 Oxyopinse, including Oxyopes.

This genus includes the largest spiders found in the North- 

 ern States, and most of the species are of large size and covered 

 with hair. The legs are stout and thickly covered with hairs on 

 the tai'si. The front row of eyes is nearly straight and as long as 

 the second row or longer, the middle jiair usually a little larger than 

 the others. The second eyes are the largest and about their diame- 

 ter apart. The dorsal eyes are smaller and farther apart. The spin- 

 nerets are short, the hinder pair no longer than the anterior. Several 

 species dig deep holes or make shallow nests under stones, where they 

 hide while molting or carrying their young.
