■364 THE SPIDERS OF THE TYNE VALLEY. 



America (McCook). Be that as it may, in Britain it 

 is seldom found far away from greenhouses. 



Theridion lineatum (Bl.). Abundant in Tynedale, and 

 widely distributed in Europe and North America. Adult 

 in summer, and found amongst leaves and herbage, where 

 its beautiful green colour probably helps to conceal it. 



Theridion denticulatum (Walck.). Not very common, 

 but may be beaten from the branches of conifers, or 

 observed in the crevices of lichen-covered bark. Adult 

 in May and June. Of wide distribution. 



Theridion varians (Hahn). Very common on trees and 

 shrubs, and in the angles of porches, etc. Abundant 

 everywhere. 



Theridion sisyphium (Clerck). As beautiful and as 

 widely distributed as most of its congeners. It especially 

 favours gorse and holly bushes. Its beautiful tent-like 

 retreat must be familiar to all possessors of a garden. 



Theridion pallens (Bl.). Common on shrubs and trees 

 of all kinds. Adult in May and June. 



Theridion vittatum (Koch). Not very abundant, but 

 may be beaten occasionally from oak trees or gorse 

 bushes. Rare in Ireland, and unrecorded for Scotland. 

 It is common in the South of England, becoming rarer in 

 the North, where, however, it has occurred in Lancashire 

 and Cumberland. Widely distributed abroad, and adult 

 in May and June. 



Theridion bimaculatum (Linn.). Occasional among 

 grass and herbage on the ground. Unlike the other 

 species of the genus, this spider seems to lead a wandering 

 life, the females carrying their egg sacs with them. The 

 males are adult in May and June, the females throughout 

 the summer. It has occurred in various Irish localities, 

 but is not on record for Scotland. In England it is 

 reported from Dorset, Bucks, Surrey, Sussex, Glamorgan, 

 Lancashire, Yorkshire, and North Wales. European dis- 

 tribution wide.
