Glen, county of Antrim, -where Mr. "Workman took an adult male m> 

 iS'ovember, 1889 ; Londonderry, -whence Mr. J". IT. Milne sent me a 

 pair of adiilts in May, 1895; and Glenasmole, in the Dublin moun- 

 tains, where I found an adult male in June, 1895. In Great Britain, 

 Sweden, and France, this species seems of local, though wide distri- 

 bution. It extends into Corsica, and occurs in both northern an.d 

 southern Germany, in Austria, and in northern Hungary. 



Le^MTiyjylxantes terricola (Koch). 



LinypJiia alacris^ Bl. (Spid. G. B. I.). 



Lllster, Connaught. 



This spider has been sent me in some numbers from Londonderry by 

 Mr. J. IS". Milne (1895). Elsewhere in Ireland, single specimens have- 

 been obtained at Colin Glen, county of Antrim ; Poyntzpass, county of 

 Ajrmagh ; iSi"ewcastlc, county of Down ; and Clonbrock, county of Gal- 

 way. Adults have been found in May, September, and October. L.. 

 terricola seems to be a northern and alpine species. Though, of wide 

 distribution in Great Britain, it is much commoner in Scotland and the 

 north than in the south, of England ; while in central and southern 

 Europe it appears to be confined to mountainous districts. 



Le2JM'hyp'hante8 mimitus (Bl.) 



Linyphia minuta (BL), Spid. G. B. I. 



Ulster, Connaught, Munster, Leinster. 



This spider is widely distributed in Ireland : counties of Donegal,. 

 Londonderry, and Antrim, to Skibbereen, county of Cork ; Dublin to 

 Clonbrock, in county of Galway. The absence of records from Coime- 

 mara is probably due to want of observation in autumn. Adults are 

 most numerous in September and October, and have been taken in 

 January. In June, July, and August, immature examples occur; some 

 specimens attain maturity in the last-named month. Z. minutus is 

 generally distributed in Great Britain, extending at least as far north 

 as Inverness-shire. On the Continent it is common in northern Europe, 

 but scarcer in the south. It also inhabits ISTorth America. 



Lephthyphantes leprosus (Ohl.). 



Ulster, Connaught, Leinster. 



The only localities where this spider has been taken in Ireland are 

 Londonderry, Athlone, Dublin, and Lucan. Adults have occurred in 

 May, June, July, and August. Like L. minutus, this is a widespread 

 species in Great Britain. Abroad it has, in the Old World, a wider range
