under a thin filmy web, at other times quite exposed, the web 

 having been perhaps torn off in raising the stone. 



I have received both sexes, in the adult state, from Lydney in 

 Gloucestershire; and very recently an adult female has been 

 found near Sherborne by my nephew, Frederick Octavius P. 

 Cambridge.

The adult male measures but one-tenth to £th of an inch in 

 length, the female being rather larger. 



The colour of the cephalo-thorax is dull reddish-yellow, with a 

 black linear margin, and suffused, especially in irregular, converg- 

 ing lines on the sides, with dark brown tinged with olive. The 

 legs are very long, particularly those of the first and fourth pairs, 

 and the femora are broad, but of a somewhat flattish form ; two 

 parallel rows of longish spines are disposed longitudinally under- 

 neath the tibise and metatarsi of the first and second pairs ; their 

 colour is a clear coppery-yellow, with the femora, tibite, and meta- 

 tarsi of tho first and second pairs, as well as the tibise and meta- 

 tarsi of the third and fourth, strongly suffused with blackish olive- 

 brown. 



The palpi are similar to the legs in colour ; they are long, and 

 the radial is larger than the cubital joint ; the radial apophysis is 

 short, blackish, slightly bent, and somewhat obtusely pointed at 

 its extremity. The digital joint is small, and the palpal organs 

 simple. The upper side of the abdomen is yellow, much 

 suffused with dark olive-brown in front, and with a longitudinal 

 series of very distinct, dark brown, angular bars on the hinder 

 part ; in some examples these bars might be more correctly 

 described as yellow on a dark-brown ground. The adult female 

 resembles the male in colours ; but there is some variety in the 

 brightness and distinctness of colouring in the individuals of a 

 long serios of both sexes,
