372 THE SPIDERS OF THE TYNE VALLEY. 



Dicymbium nigrum (BL). Common, especially among 

 grass in pastures. Adult throughout the year, but most 

 commonly in autumn. Widely distributed at home and 

 abroad. 



Dicymbium tibiale (BL). Can generally be found amongst 

 moss and grass in damp places in the woods. Very 

 seldom found elsewhere. It occurs in Donegal in 

 Ireland, and in Devonshire, Warwickshire, Staffordshire, 

 Glamorgan, North Wales, Cheshire, Yorkshire, Cumber- 

 land, and Berwickshire. It is widespread on the 

 Continent, but in these islands appears chiefly of 

 northern and western range. 



Pocadicnemis pumila (Bl). This differs from the eighteen 

 preceding species, and resembles the next two, in its season 

 of maturity. The males become adult in May and June, 

 and are over before August; the females may be found in 

 autumn, but both sexes pass the winter in an immature 

 state. • Very abundant amongst grass and herbage. It 

 occurs throughout Britain (Dorset to Edinburgh), but is 

 commoner in the north. It is unrecorded for Ireland, 

 but occurs on the Continent, where it is widely distri- 

 buted. 



Peponocranium ludicrum (Camb.). Frequent in the 

 heather districts. Season as in the last species. Widely 

 distributed in Britain (Dorset to Edinburgh), occurring 

 wherever gorse and heather abound. Abundant in the 

 Isle of Man, but not recorded for Ireland. On the 

 Continent has only been observed in France, and there 

 only in the north. 



Metopobactrus prominulus (Camb.). Several speci- 

 mens of each sex on grassy banks in June. A rare spider, 

 the only other British records being Dorset, Sussex 

 (Hastings), Glamorgan, Cheshire, and Yorkshire. It is 

 found in nearly all the European countries ; its three 

 congeners on the other hand being confined to Spain, 

 Corsica and France, and Hungary respectively.
