fically identical with the two males. In L. pullata the legs 

 of the female are generally, though not often very distinctly, 

 annulated, while those of the male have rarely any trace of 

 annulation ; the general hue of L. pullata is also much more 

 of a yellow-brown, while Lycosa riparia is nearly black. 

 This spicier has not before been recorded as British.

Very nearly resembling in its general appearance and pattern 

 L. amentata, but smaller, L. prativaga has passed for a variety 

 of that species in my collection for some years past, having 

 been also returned to me at the time of capture by Mr. Blackwall 

 as small examples of his L. saccata. It is, however, more 

 nearly allied to L. pullata and L. riparia ; its legs are very 

 distinctly annulated ; and the oblique palpal-organ spine, while 

 very like that of L. pullata, has another fine one almost be- 

 neath and nearly concealed by it ; this additional spine is also 

 present in L. pullata, but it is in that species much stronger 

 and more visible. 



From L. amentata, Clk. (L. saccata, Bl.), the much smaller 

 size of the digital joints of the palpi will easily distinguish it. 



The female resembles the male in colours and markings ; and 

 the genital aperture is characteristically different in form from 

 that of both L. pullata and L. amentata. 



Examples of both sexes have been found at Bloxworth and 

 other localities in Dorsetshire ; but hitherto it has not been re- 

 corded as British under its proper designation.

A comparison of the examples recorded, I. c. supra, with 

 typical specimens of A. arcuatus received both from Dr. Tho- 

 rell and Dr. Koch prove them to be identical. The female 

 has not yet been found in Britain.
