lateral furrows widest anteriorly, where they are also comparatively deep, 

 narrowed posteriorly by the inward protrusion of the side walls, the 

 channels leading to the spermatheca being thus much contracted ; 

 transverse arms of guide not divided. Scopus borne at exterior side of 

 bulb ; transverse in position and attached along front side well distad, 

 bearing a subapical more or less retrorse process or barb ; median margin 

 of furrow of conductor bearing one or sometimes two slender needle- or 

 blade-like and always simple tenacula. Lectus well developed, with a 

 distinct auricula of moderate size. 



ScHizocosA, n. gen. 



Epigynum with a distinct guide, which is elevate and well developed 

 anteriorly as in Lycosa ; transverse arms of guide double (i. e., divided 

 from their exterior ends mesad a varying distance) ; lateral furrows 

 not widening anteriorly, the sides straight or nearly so and subparallel. 

 Bulb of male palpus bearing a scopus transverse and exterior 

 in position with a subapical process or barb ; superior furrow of 

 conductor ill-defined, showing no rugae. Conductor elevated at its 

 exterior end anteriorly and more or less produced into a horn-like process 

 of varying length ; median rim bearing more or less ectad of its middle a 

 basally broad and apically-poinced, relatively short, plate-like tenaculum, 

 which is curved backward and dorsad distally, a shorter similarly stout 

 secondary tenaculum ectad and cephalad from the first. Auricula of 

 lectus very long, extending forward along the side of the conductor and 

 attaining, or nearly attaining, the front margin of the alveolus. Embolus 

 distinctly angled or elbowed at base of auricula. Lunate area very small. 



PiRATA, Sund. 



Epigynum possessing no true guide, in most cases presenting behind 

 two more strongly-chitinized lobes or tubercles upon which the 

 spermatheca open free. Bulb of male palpus bearing a scopus in a 

 median and subapical position ; its base attached on front face of basal 

 lobe of bulb ; its principal branch reaching to or in most extending 

 beyond the front margin of the alveolus ; a basal process of large size. 

 Embolus small, nearly or quite concealed by proximal part of scopus. 

 Lunate area large, fully one-third or more the total length of the bulb.
