Eev. F. O. Pickard-Cambridge on British Spiders. 29 



The spinous armature of the legs is as follows : — 

 Femora i. — 2 dorsal, longitudinal ; 2 lateral, anterior, 



apical spines. 

 Femora ii. — 2 dorsal, longitudinal ; 1 lateral, anterior, 



apical spine. 

 Femora iii. — 3 dorsal, longitudinal ; 2 lateral, anterior, 



apical ; 1 lateral, posterior, apical spine. 

 Femora iv. — 3 dorsal, longitudinal ; 2 lat( 

 apical ; 1 lateral, posterior, apical spine. 

 Patella i. and ii., no spines ; iii. and iv., 1 posterior cen- 

 tral, 1 anterior central spine. 

 TihicB (iDcneath only) i. — 3 pair ventral, longitudinal ; 



1 anterior, lateral, apical spine. 

 TihicB ii. — 3 pair ventral longitudinal (2 rudimentary 



anterior) ; 2 lateral, anterior, apical spines. 

 TihicB (above and beneath) iii. and iv. — 3 pair ventral, 

 longitudinal; 2 lateral, anterior ; 2 lateral, posterior ; 

 1 dorsal, apical spine. 

 Protarsi (beneath only) i. and ii. — 3 pair ventral, longitu- 

 dinal ; 1 ventral, apical ; 1 anterior, latei-al, central spine. 

 Protarsi iii. (above and beneath). — 3 pair ventral longitu- 

 dinal ; 1 ventral apical ; 3 anterior lateral ; 3 posterior 

 lateral spines. 

 Protarsi iv. — 8 ventral spines ; 3 anterior lateral ; 3 poste- 

 rior lateral spines. 

 Falces of male similar in general respects to those of 

 terricola ; no tooth on outer margin of fang near base. 



Pal'puH of male similar in general respects to that of terri- 

 cola^ but the radial joint or tibia bears on the inner underside 

 in front a cluster of \'2 to 16 stiff, almost straight, stout spines. 

 The tarsal or digital joint has no claio at its apex. 



This tine species, apparently new to science, may be 

 readily distinguished in both sexes from the other three species 

 of Lycosa, to which it is allied, by its umber-brown hue and 

 pale- speckled abdomen ; in the male sex by the cluster of 

 spines beneath the radial joint on the under and inner side. 



In the female sex by the epigynal area, which is longer 

 than broad, while the whole area is larger in proportion than 

 that of any of the others, save terricola ; but in terricola the 

 area is broader than long, semicircular. 



There is no difficulty whatever in recognizing the males of 

 this species, though it might not be altogether easy to separate 

 the females if tiiey had lost their colour at all. But if it be 

 borne in mind that this species, robusta, and ruricola exhibit 

 the short pale wedge-shaped bar on the abdomen at base, and 

 that the epigynal area of ruricola is very small and incon-
