7. Transverse arms of guide divided from the distal end more or less 

 mesally; auricula of lectus very long, reaching or nearly reach- 

 ing the anterior margin of alveolus; the embolus distinctly 

 elbowed at base of auricula ; conductor conspicuously elevate 

 and usually more or less produced into a horn-like process 

 extending beyond front margin of alveolus, . Schizocosa. 

 Transverse arms of guide not divided from apex mesally ; auricula 

 of moderate size or small, not attaining front of alveolus; 

 embolus evenly curving, not elbowed at base of auricula; 

 conductor not conspicuously elevate or produced above into 

 a horn-like process extending beyond front margin of alveolus,

 FABDOSA C. Koch, 1848. 



(Subgenus sub LYCOSA. Die Arachn., Vol. 14, p. 100.) 



Entire body densely clothed with pubescence. Anterior tibise 

 armed beneath with three pairs of spines, of which the basal and 

 median pairs are very long, much longer than the diameter of the 

 joint, the third pair apical in position and reduced in size. Anterior 

 row of eyes always shorter than the second and procurved ; eijes small 

 and subequal or with the median a little larger; median eyes nearly 

 always a little farther from each other than from the lateral ; clypeus 

 high, twice as wide as the diameter of an anterior lateral eye; eyes 

 of the second row large and divergent, situated at the outer angles of 

 the face above, their diameter or more apart; quadrangle of posterior 

 eyes trapeziform, wider behind than in front. Labium at least as 

 wide as long, usually wider; basal excavation short, only very rarely 

 more than one-fourth of the total length of labium. Spinnerets short, 

 the posterior pair a little longer than the anterior, the apical segment 

 being short and rounded. Epigynum with a distinct guide which is 

 but weakly or not at all developed anteriorly; the openings of the 

 spermatheca protected; the spermathecum on each side opening into 

 a relatively large and deep fovea or pit, the furrows becoming nar- 

 rower and shallower anteriorly. Posterior lobe of mah palpus bearing 

 a Scopus in a median position; scopus more or less erect, free except 

 at base where it has a spur or process on the exterior side; scopal fold 

 low; when a true lectal fold is indicated never showing an auricle or 

 f orwardly directed lobe ; lower furrow of conductor relatively extensive, 

 bearing at its inferior margin a variously formed and often lobed or 

 dentate tenaculum.
