THE SPIDERS OF THE TYNE VALLEY. 395 



is widely distributed on the Continent and at home. 

 Here, however, it seems very local. It is fairly common 

 in Dorset, and has occurred in Cheshire, North Wales, 

 Cumberland, and near Edinburgh. In Ireland, too, it is 

 widespread, but is not recorded for Ulster. It is probably 

 spread thinly all over England. 



Tetragnatha extensa (L.). Occasional on the moors, 

 where it is generally found near water. Adult through- 

 out the summer. Holarctic. 



Tetragnatha Solandrii (Scop.). Much commoner than 

 the last, and nearly always occurring in woods. It is 

 generally beaten from the branches of trees. Adult 

 throughout the summer, and generally distributed in 

 Britain, Ireland, and Europe. 



Tetragnatha obtusa (Koch). An adult male was beaten 

 from a spruce growing on the banks of the Devil's Water 

 in August. It is not rare in Dorset, Epping Forest, 

 Buckinghamshire, and the South, but seems very rare 

 in the North of England. It is, however, widely dis- 

 tributed in Ireland and on the Continent. 



Meta segmentata (Clerck). An abundant spider, widely 

 distributed at home and abroad. Adults and immature 

 individuals may be found side by side almost throughout 

 the year. Every winter adults were found hibernating in 

 outhouses, etc. In Tynedale there are not two distinct 

 generations as far as I can make out, the majority of 

 individuals being mature in autumn, and the spring brood 

 {M. Mengli, Bl.) being explained by hibernation. 



Meta Merianae (Scop.). This spider accompanies Nesticus 

 celliinamis (Clerck) and Leptyphaiites pallidus (Camb.) in 

 their shady, dark, and cool retreats under the banks of 

 streams and ditches in the woods. It is especially fond 

 of undermined banks overhung with dank vegetation. 

 Sometimes also found in outhouses and cellars. M. 

 Meriance (Scop.) is very widely distributed, and adults 

 may be found throughout the year.
