in form. The integument of the posterior extremity of the 

 abdomen is marked with some transverse foldings. 



Found on a wall, in the month of June, 1877, at Bloxworth. 



LINYPHIA BICOLOB. 



Neriene bicolob, Blackto., Spid. Great Brit, and Irel., p. 250, pi. 

 xvii., fig. 168. 



The male measures l-6th of an inch, though among a series of 

 examples there will be found considerable diversity of size, some 

 larger and some smaller than the measurement given above. 

 This diversity is observable in both sexes. 



The caput is very slightly, but not abruptly elevated, rising 

 gradually from the hinder slope of the thorax. It has some 

 bristly hairs on and behind the ocular region. The cephalo- 

 thorax is of a reddish yellow-brown colour, and the legs and 

 palpi are of a rather lighter hue. The spines on the legs are 

 distinct, but not very strong. The palpi of the male are moder- 

 ately long ; the cubital and radial joints short ; the former 

 is less strong than the latter, and has a single, long, tapering 

 bristle at the fore extremity on the upper side. The radial joint 

 has a small obtuse protuberance on the outer side of the upper 

 part, furnished with a compact group of long, strong, somewhat 

 spinous, black bristles, of equal strength throughout their length. 

 The digital joint is not large ; its form is roundish-oval, with a 

 prominent lobe on its outer side, and a large obtuse process at 

 its base. The palpal organs are prominent and complex ; among 

 the most conspicuous of their processes is a curved one near the 

 base on the outer side. 



The abdomen projects well over the base of the cephalo-thorax, 

 and is of a brownish-black colour. 



The female resembles the male in colours, and is usually 

 larger. 



Eare among heather, and herbage in woods, at Bloxworth, 

 but apparently much more numerous in the north of England, 

 Scotland and Wales.
