the fii-st. or less commonly longer and conical (Sosippus) ; median pair 

 slender, of moderate length. 



Body clothed with simple hair, or more rarely with some of plumose 

 ty]3e intermixed (Sossipus and some Pardosas). 



Genital plate or epigynum of the female mostly simple ; either a simple 

 iinfurrowed plate or a plate depressed or furrowed longitudinally and 

 with the depressed area divided by a ridge-like elevation (guide), which 

 in the large majority of cases extends laterally on each side at its 

 posterior end. The transverse portion of the guide often (Lycosa 

 sens, str.) distinctly more elevate than the septal portion immedi- 

 atel}' in front of it and extending on each side to behind the openings of 

 the spermathecse ; median piece of guide posteriorly and the transverse 

 pieces on anterior side with the upper free edges mostly more or less 

 •extended horizontally in plate-like expansions, which are usually 

 narrow but may be wide (lateral plates or alee of guide). 



Palpus of the male long, differing uniformly from that of the most 

 nearlj' related families {e.g., Pisauridce and Agelenidos) in never having 

 femur, patella, or tibia armed with any manner of process or apophysis. 

 Tarsus or cymbium comparatively simple, boat-shaped; completely 

 covering the bulb, the alveolus occup5dng usually not more than two- 

 thirds of the ventral area; terminal part of the tarsus acuminate and 

 bearing one, two, or rarely three mostly stout, always untoothed 

 spines (transformed claws), occasionally imarmed. Bulb compara- 

 tivel}- simple and compact; embolus only rarely exerted, in most 

 h'ing upon a special fold (lectus) at front of the larger basal lobe or 

 division, this fold in many with a lobe {auricida) extending forward in 

 front of its exterior end ; lobe of the conductor bearing one to several 

 chitinous processes (tenacula); either an erect and conspicuous apo- 

 physis (Pirata) or transverse, and appressed ; basal division of bulb bear- 

 ing strongly chitinized fokl or apophysis (scopus) in a median (Pardosa) 

 or exterior position (Lycosa), or with such fold or apophysis absent or 

 but weakly developed (Pirata), its absence or weak development being 

 correlated with the absence of furrow and guide in the epigj'-num of 

 the female; a chitinous plate or area (lunate area) at base of bulb 

 practically alwa3's exposed, the area being of varying size in the differ- 

 ent genera, but of quite constant relative extent and position in each. 



The most simple and generalized condition is shown in Pirata.
