The spinous annatiire of tlie leers Is as follows : — 



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



apical spines. 

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



apical sj)inc. 

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



apical ; 1 lateral, posterior, apical spine. 

 Femora iv. — 3 dorsal, longituiliiial ; 2 lateral, anterior, 



apical ; 1 lateral, posterior, apical spine. 

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

 tral, 1 anterior central spine. 

 Tibice (beneath only) i. — 3 ])air ventral, longitudinal ; 



1 anterior, lateral, apical spine. 

 Tihue ii. — 3 pair ventral longitudinal (2 rudimentary 



anterior) ; 2 lateral, anterior, apical spines. 

 Tihice (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, a])ieal; 1 anterior, lateral, central spine. 

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

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

 lateral spines. 

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

 rior lateral spines. 

 Folccs of male similar in general respects to those of 

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



Falpus 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 \(S stiffs almost straight^ stout spines. 

 Tlie tarsal or digital joint has no cluio at its apex. 



This fine species, a])parently new to science, may be 

 readily distinguished in both sexes from the other tiiree 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 e|)igynal 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 they had lost their colour at all. But if it be 

 borne in mind tiiat 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-
