summer of 1897, and Ashford, county of Wicklow, where I took an 

 adult male in June, 1898. It seems to be a southern species ; although 

 it extends its range into Scotland and southern Sweden, it is rare in 

 those countries. It occurs in the Channel Islands, throughout France, 

 in central Russia, in Austria, and in Hungary (northern, eastern, and 

 western), and in northern Italy. 



Nesticus cellulanus (Clerck). 



Linyphia crypticolens, Bl. (Spid. G. E. I.). 



Ulster, Leinster. 



The only localities whence I have received this spider are Ennis- 

 killen, Londonderry, Drogheda (in the Dowth tumulus), and Leixlip, 

 county of Kildare. Adults occur from July to September. Doubtless 

 the spider is widely distributed in Ireland, but, owing to the under- 

 ground and concealed places where it lives, not often observed. 

 Eanging at least northward to the Grrampians in Great Britain, it is 

 distributed over central and southern Europe, but is a very rare 

 spider in northern Germany and Scandinavia, though in Russia it is 

 recorded from the neighbourhood of Moscow. 



Theridion iimaculatum (L.). 



T. carolinum, Bl. (Spid. G. B. I.). 



Ulster, Leinster. 



This species is recorded by Mr. Workman (1880) without locality. 

 It is not scarce in eastern Ireland, having been found at Portmarnock 

 and Glendhu, county of Dublin ; Maynooth, coiuity of Kildare ; Bray 

 and Avoca, county of "Wicklow. Adults occur in May and June, also 

 in September. In Great Britain this spider seems only to have been 

 noticed in Dorset and Lancashire. It occurs throughout Erance (also 

 Channel Islands and Corsica), and in Sweden, Germany, Austria, 

 Hungary, Croatia, and northern Italy. 



Theridion Uneatum (Clerck). 



Ulster, Connaught, Munster, Leinster. 



This is one of our commonest spiders. It ranges from Londonderry 

 and the county of Antrim to the counties of Waterford and Cork 

 (Skibbereen) ; from Dublin to Connemara (found on Inish McDara) ; 

 and extends into the south-western peninsulas (Kenmare, Derrynane). 

 In Great Britain its range is also general, and it occurs throughout 

 Europe, as well as in North America.
