LYCOSA RIPARIA. 



Lycosa riparia, C. L. Koch, Die Arachn xv., p. 29, tab. 512, 

 figs. 1435-6, and Ccmlr. Ann. and Mag.

The length of the male is 2£ lines, and of the female 3 linos. 



This spider, though nearly allied and very similar, may be 

 distinguished from the f orogoing (L. proximo) by sovoral constant 

 and easily observed characters. First, the whole spider is less 

 dark coloured, the central thoracic stripe, which is clothed with 

 whitish hairs, is less vivid and soldom reaches the ocular area. 

 The lateral thoracic stripes, though irregularly odged, are seldom 

 completely broken. The legs are longer and more distinctly 

 annulated, the tibise especially, the metatarsi only faintly so ; 

 none of the femora are at all suffused with black, the anuuli 

 being all distinct. The whole spider has in fact a more variegated 

 appearance from all the paler portions boing usually clothed 

 with grey or whitish hairs. 



The palpi are longer than in L. proximo,, and pretty thickly 

 clothed with coarse black hairs ; the hairs on the digital joint 

 soften off into a greyish mouse-colour at its fore part which is 

 itself of a dull yellow-brown hue; the form of this joint is 

 elongate-oval, terminating with a strongish curved claw. The 

 palpal organs have a strong, slightly curved, oblique spine near 

 the centre. The point of this spine reaches quite to, and even 

 slightly beyond, the margin of tho digital joint ; just in front 

 of it is a much finer spine, which issues from near the inner 

 margin of the joint. 



The abdomen is marked very like that of Lycosa proximo,, but 

 the pattern is gonorally more distinct and discernible. The 

 central longitudinal portion of the upper side is usually 

 rather reddish-brown. The normal marking on the fore half is
