348 THE SPIDERS OF THE TYNE VALLEY. 



widespread. In Britain it occurs from the Channel Islands 

 to Berwickshire, reaching an altitude of nearly 3,000 feet 

 on the Cumberland mountains. 



Clubiona trivialis (L. Koch). Not rare in the heather 

 districts near Hexham. In the summer it may frequently 

 be beaten from the topmost shoots of that plant. Adults 

 of both sexes may be found from May till September. 

 This spider is common in Scotland and the North of 

 England, but ver)' rare in the South. It has occurred in 

 the North of Ireland. On the Continent its distribution 

 is northern and eastern, and it is not recorded for Western 

 France or the Iberian Peninsula. 



Clubiona reclusa (Camb.). An abundant spider, occurr- 

 ing in every wood and hedgerow, and on every grassy 

 bank in the district. Both sexes are adult throughout 

 the summer. Widespread in Britain, Ireland, and on the 

 Continent. 



Clubiona grisea (L. Koch). Not common, but occurs 

 occasionally in swamps, such as that formed by the 

 Erring Burn at Chollerton. Widely distributed in Britain, 

 it occurs in Ireland, and has been recognized in France, 

 Germany, and Hungary. 



Clubiona holosericea (De Geer). This is another marsh 

 loving species. Mr. Falconer found it at Houtley by the 

 side of the river Devil's Water. It is common in most 

 parts of Britain, Ireland, and Europe, but as I never met 

 with it myself in Tynedale it can hardly be very abundant 

 there, though it may easily occur in many districts I have 

 not explored. It is nearly always found near water, and 

 I have noticed that the comparatively rare specimens 

 found in dry places are generally of stunted growth. 



Clubiona pallidula (Clerck). Not very common, but may 

 be beaten out of ivy or holly bushes, or extracted from 

 cracks in walls, etc. It is adult in May and June, and is 

 of wide distribution.
