Key to North America Genera of Lycosid.e. 



1. Anterior tibia? armed beneath with five pairs of very long spines; 

 anterior eyes subcontiguous, in a recurved row clearly longer 



than the second, .• Sosilavs. 



Anterior tibis armed beneath with less than five pairs of spmes ; 



anterior row of eyes straight or procurved, 2 



2 I^ower margin of furrow of chelicera armed with four stout conical 



teeth, • • • SosiPPL-s. 



Lower margin of furrow of chelicera armed with two or three 



teeth, never with four, ' ' '^' 



3. Anterior row of eyes very strongly procurved, the median eyes 



much farther from the lateral than from each other, Trabea. 



Anterior row of eves not strongly procurved, the median eyes 



little or mostly 'not at all farther from the lateral than irom 



each other, Z ' / /• • 



4 Cephalothorax glabrous or very nearly so, smooth and shming, 



dark in color and without definite light markings, Allocosa. 



Cephalothorax not glabrous, when but sparsely pubescent having 



a distinct light colored median stripe, ....... 5. 



5 Distal pair of ventral spines of anterior tibia? never apical in posi- 



tion- cephalothorax with a median pale band enclosing in its 

 anterior portion a dark V-shaped mark. (Epigynal plate unfur- 

 rowed, i.e., without a guide; true scopus absent or but faintly 



indieatfed in male palpus), • • PiRATA. 



Distal pair of ventral spines of anterior tibise apical m position; 

 median pale band of cephalothorax when present not enclosing 

 anteriorly a dark V-shaped mark. (Epigynum with a distinct 

 guide; scopus well developed), ^• 



6 Scopus median in position and more or less erect; guide of epigy- 



num weakly or not at all developed anteriorly, the spermatheca 

 opening into comparativelv deep, open, basin-hke fovea?, 

 which when continued forward as furrows are distinctly less 

 depressed anteriorlv ; labium wider than long with basal exca- 

 vations short, . : • Pardosa 



Scopus exterior in position; guide of epigynum well developed
