20 F. P. SMITH ON THE BRITISH SPIDERS OF THE GENUS LYCOSA. 



central and lateral bands ; in the female these bands have so 

 greatly expanded that the black part is reduced to a few patches, 

 often almost obsolete. Legs yellowish brown, with dark markings 

 and sometimes indistinct annulations. Tarsi and metatarsi of 

 the first pair of legs, in the male, thickened and furnished with 

 numerous erect bristles. 



This is perhaps the most striking and beautiful of our indige- 

 nous species of Lycosa, its pale, hairy clothing rendering it a most 

 conspicuous object. Unfortunately, it is rare and local. It has 

 been taken in England, Scotland, and Ireland, and has a fairly wide 

 range in Europe — Germany, Norway, Russia, etc.; but it appears 

 nowhere to be at all common. Adult in spring and summer. 



Lycosa herbigrada, Bl., var. intermedia, no v. 



(PI. 4, Fig. d.) 



Length : male, 5*5 mm. ; female, 6*5 mm. 



This variety occupies an intermediate position between L. 

 herbigrada, Bl.,and L. palustris, (Linn.), differing from the former 

 by its somewhat smaller size, by its body being less plentifully 

 supplied with hoary pubescence, and by the central thoracic band 

 being narrower than in that species. This band usually shows 

 some dilation behind the eyes, but it is, as a rule, slight. In 

 some cases, however, it is almost identical with that of the 

 typical L. palustris, (Linn.) ; and the lateral bands are generally 

 intermediate in width between the very broad ones of L. 

 herbigrada, Bl., and the narrow ones of L. palustris, (Linn.). 



This variety appears to be rare, but as it is fairly well known 

 it seems advisable, for the sake of convenience of reference, that 

 it should possess a distinctive title. As I cannot find any note of 

 such a name having been definitely bestowed, I propose the 

 varietal name intermedia.
