rather large, and has a slender curved process at its base on 

 the outer side, and a largish lohe near its extremity on the inner 

 side. 



The female is larger and generally more distinctly marked 

 than the male. 



Linyphia nigrina is not rare on low plants and herbage, among 

 young underwood, at Bloxworth, find in various other localities 

 in Dorsetshire in the summer and early autumn months. It is 

 also found in other parts of England, as well as in Scotland. 



LINYPHIA APPROXIMATA. 



Linyphia approxbiata, Cambr., Linn. Trans, xxvii., p. 424, pi. 

 55, No. 19. 



Length of the male l-9th of an inch. 



This spider is very closely allied to both the foregoing, but may 

 be distinguished from them without difficulty. 



The caput is only very slightly raised above the rest of the 

 cephalo'thorax, which is of a yellowish colour, slightly clouded 

 with dusky, and sometimes marked on the sides with converging, 

 indistinct, sooty lines. The legs are dingy yellow, their relative 

 longth is 1.2.4.3., and the spines are few, fine, and semi-erect* 

 The palpi are short, the digital joint large, of irregular form, 

 and (including the palpal organs) as long as the whole of the 

 rest of the palpus. These organs are very prominent and 

 complex, with a short, slender, circularly curved spine at their 1 

 extremity. 



The abdomen is nearly black, with a series of strong, angular 

 markings of a pale whitish colour along the middle of the upper 

 side. The vertices of these markings are sometimes obsolete; 

 The female is larger, but resembles the male in colours and 

 markings. 



From Linyphia nigrina Westr., the present species may be dis- 

 tinguished by the much larger size of the digital joint and palpal 

 organs. The structure also of these organs differs, as well as 

 the pattern on the abdomen. From Linyphia pullata Cambr. it
