Dublin to Achill, Connemara, Inish. M'Dara and Inishmore, Aran, as 

 well as into the far south-western peninsulas (Dingle, Yentry, Caher- 

 civeen, Derrynane). Adults occur in Ireland not only in May and 

 June (the months given by Mr. F. Cambridge (1895) for Great Britain), 

 but throughout the year from January till October. The eggs 

 are laid in May ; young spiders are found in July and onward 

 through the autumn, half-grown individuals in July, and almost 

 mature specimens in August. It seems, therefore, that these spiders 

 do not reach maturity until the autumn of the year after hatching, 

 and that they survive the winter in the adult state to pair and lay 

 eggs in the succeeding May. This spider is widely distributed in 

 Great Britain (northwards to the Grampians), and ranges on the 

 Continent from Lapland and northern Finland to southern Spain, the 

 Mediterranean Isles, and Greece, as well as to eastern Siberia. 



Lycosa terricola, Thorell. 



L. agretyca, Bl. (Spid. G. B. I.). 



Ulster, Connaught, Munster, Leinster. 



This spider is as common and widespread as Z. ruricola in northern, 

 eastern, and western Ireland, extending into Limerick, Clare, and Con- 

 nemara, as well as into theislets (Inish M'Dara and Inishmore) off the 

 coast of Galway and Achill, county of Mayo. It has been found at 

 Ferns, county of Wexford, and Skibbereen, county of Cork, whence it 

 may be inferred that it is equally widespread in the south. It occurs 

 over 2000 feet np on the hills. In the south-western peninsulas it 

 has occurred in Dingle and Kenmare. Adults have been noted in all 

 months from March till October, and the life cycle is presumably 

 similar to that of L. ruricola. This spider varies greatly in colour as 

 well as in size. Some specimens of the female are bright red-brown, 

 others deep blackish brown. One of the latter variety taken on the 

 shores of Lough Derevaragh, county of Westmeath, was erroneously 

 recorded as L. andrenivora, "Wick, (Dublin ISTat. F. C, 1892). This 

 species is generally distributed in Great Britain (northward to the 

 Grampians at least), and on the Continent ranges from 65° N, lat. in 

 JSTorway into north Africa and Turkestan. 



Pirata hygrophilus, Thorell. 



Lycosa piscatoria, Bl. (Spid. G. B. I.). 



Connaught, Munster. 



The only Irish examples of this spider yet found are a male from 

 Limerick, taken June, 1895, and a female from Mote Park, county of 

 Eoscommon, taken June, 1897, both collected by Mr. J. N. Halbert. 

 A local species in Great Britain, P. hygrophilus is recorded only from
