which is itself commonly bisected longitudinally by a yellowish 

 line. The third or last denticulation (on the hinder part) is 

 represented by a transverse yellow-white stripe, generally 

 detached from the main band. The under side and sides are of 

 a dull red-brown colour. 



The female is much lighter coloured than the male, and its 

 markings, though resembling thoso of that sox, are very indis- 

 tinct. The edges of the upper side of the abdomen are marked 

 with, here and there, a black spot. 



This is a rare spider, but it occurs occasionally at Bloxworth 

 running on footpaths and bare spots in meadows in the month 

 of June. On one occasion (in 1878) I found an adult male among 

 moss and grass in a damp meadow, as late as tho 21st of Septem- 

 ber. It has also been met with in other parts of England, as 

 well as in North Wales and Scotland.

The male measures l-6th of an inch, or 2 lines, in length; the 

 female is rather larger and considerably more robust. 



This spider is nearly allied to Xydicus erraticus, Blackw., 

 resombling it very closely in colours and markings. It may, 

 however (in tho male sex), be distinguished without much 

 difficulty, first by the form of the abdomen, which is of a moro 

 elongated shapo ; next by the form of the dentated band on the 

 abdomen, the denticulations on the hinder part being represented 

 by transverse stripes, the foremost (and frequently the second) 

 being very distinctly defined ; in fact, the foremost cuts the 

 upper side into two parts in a very conspicuous way. The foro 

 part of this band is sometimes slightly suffused with roddish- 

 brown, and always has six or eight small red-brown spots
