396 THE SPIDERS OF THE TYNE VALLEY. 



Nesticus cellulanus (Clerck). Not common, but occasion- 

 ally found in the situations described for the last species. 

 It also occurs under stones in dark places in the woods, 

 and sometimes in drains, sewers, etc. Adult in summer 

 and autumn. Very widely distributed, though apparently 

 never very abundant. 



Sub-Family III. ARGIOPIN^. 



Zilla X-notata (Clerck). Very abundant everywhere, both 

 sexes being mature in late summer and autumn. The 

 females survive the winter, and may be seen constructing 

 their webs on any warm day in that season. Of Holarctic 

 distribution. 



Zilla atrica (Koch). This is not so common a species as 

 the last. In occurs in colonies, the members of which 

 spin their webs generally on the branches of trees, 

 particularly of conifers. Adult in late summer and 

 autumn, and generally distributed at home and abroad. 



Cyclosa conica (Pall.). Two adult females were beaten 

 from heather near the Swallowship woods on May 22nd, 

 1904. Mr. Bagnall also sent me an immature male from 

 Winlaton in 1906. This is a very rare spider in the 

 North of England, but has occurred near Edinburgh, and 

 in Aberdeen, Banff, and Inverness. It has also occurred 

 once in the West of Ireland, is common in the South of 

 England, and has a wide Continental range. 



Epeira cucurbilina (Clerck). Fairly common in Tynedale, 

 where it is adult in June and July. It is generally beaten 

 from oak trees or gorse bushes. Widely distributed in 

 Britain, Ireland, and the Palaearctic region. 



Epeira triguttata (Fabr.). Immature individuals are some- 

 what frequently beaten from the branches of conifers. A 

 pair of adults were found near the Swallowship in June. 

 This is another spider which ranges north to Inverness, 

 but is much commoner in the south. It is not on record
