characteristic abdominal pattern of that species. From Linyphia 

 aeria, Cambr., it may be distinguished not only by being rather 

 larger, but by the coiled spine at the extremity of the palpal 

 organs, which is wanting in that species. 



LINYPHIA AERIA. 



Lintphia aeria, Cambr., Ann. and Mag., N.H., 1875, p. 251, pi. 

 viii., fig. 8. 



The length of the male is 1-1 3th of an inch. 



The cephalo -thorax, looked at sideways, shows a deep hollow 

 or depression between the caput and thorax, the latter being 

 slightly the most elevated of the two. It is of a yellow-brown 

 colour, with the margins and converging lateral lines of a some- 

 what more dusky-brown hue. The legs are rather long, and 

 slender ; they are of a pale dull yellowish colour, and the spines 

 are few in number, and slender, but rather long. 



The palpi are short and slender, and of the same colour as the 

 legs. The cubital and radial joints are very short ; the former 

 has a fine, tapering bristle at its fore extremity above ; and the 

 latter is the stronger, being produced a little more in front than 

 behind. The digital joint is of moderate size, and the palpal 

 organs are rather complex, but do not present any very notice- 

 able or conspicuous process. 



The abdomen is considerably convex above, projects a good 

 deal over the base of the cephalo-thorax, and is of a dull black- 

 ish colour. 



The female is rather larger than the male, but resembles it in 

 general structure and colour. 



This spider is nearly allied to the foregoing, but is smaller ; 

 its legs are also shorter, and the palpal organs have no coiled 

 spine at their extremity 4 



Found occasionally in autumn and spring at Bloxworth 

 Eectory, running on iron railings, on bright, warm mornings.
