Oarpenter — A List of the Spiders of Ireland. 185 



Linyphia triangularis (CL). 



Linyphia montana. Bl. (Spid, G. B. I.). 



Ulster, Connaught, Munster, Leinster. 



This is one of the commonest of spiders over the greater part 

 ■of Ireland, extending from the counties of Derry and Antrim to 

 Wexford ; from Duhlin to Connemara, Limerick, the county of 

 Clare, Killarney, and Kenmare. L. triangularis is a widely distri- 

 buted spider in Great Britain (Dorset, Eoss-shire) ; and on the 

 Continent ; occurring also in Siberia. In Ireland adults occur from 

 June till October, immature specimens being common in Ju.ly. 



Linyphia montana (CL). 



Linyphia marginata, Bl. (Spid. Gr. B. I.). 



Ulster, Connaught, Munster, Leinster. 



This species seems to be spread over the greater part of Ireland, 

 though I have no records from the county of Donegal, Connemara, or 

 the south-west. It has been found at Londonderry, near Belfast (1880), 

 in the county of Armagh (Armagh, Loughgilly, Poyntzpass), county 

 •of Eoscommon (Athlone), county of Galway (Clonbrock), county of 

 Waterford (Lismore), county of Wicklow (Bray), and the county of 

 Dublin (Tibradden mountain, Templeogue, Terenure, Howth). It is 

 adult in May, June, and July; immature individuals occur in early 

 summer, autumn, and winter. Generally distributed in Great Britain 

 (Dorset, Inverness). L. montana is found throughout Europe and in 

 Siberia. 



Linyphia ijisignis, Bl. 



Ulster, Connaught, Leinster. 



Probably this spider is. widely distributed and common in northern 

 and eastern Ireland. It has been found in numbers near Londonderry 

 by Mr. J. IST. Milne; Mr. Workman (1880) records it from the county 

 ■of Antrim, and has also found it in the county of Down (Craig- 

 darragh). I have taken it at Clonbrock, county of Galway; and 

 it is abundant at many places in the counties of Dublin (Santry, 

 Glencullen), Kildare (Leixlip), and Wicklow (Enniskerry, Eathdrum). 

 Adult in September and October. It is generally distributed in Great 

 Britain, but only common in Scotland and northern England. In 

 northern Europe (Scandinavia and Finland) it is common, occurring 

 as far south as eastern Prussia and Hamburg, but in France and 

 Hungary it is very rare, being found only in the neighbourhood of 

 mountains. It also inhabits Siberia and JSTorth America.
