SOME NEW AND RARE IRISH SPIDERS. 



BY DENIS R. PACK-BERESFORD, M.R.I. A. 



In the Irish Naturalist for 191 1 I published a Hst of New 

 Irish Spiders. There were additions to the " Supplementary 

 List of Spiders of Ireland " published in the Proceedings 

 of the Royal Irish Academy in March, 1909, this list being 

 a supplement to Prof. Carpenter's " Spiders of Ireland," 

 published in 1898. Since 191 1 I have published one or 

 two notes on rare species that have turned up. Very little 

 collecting has been done during the past strenuous years 

 of war, but as there are four species new to the Irish List 

 to be recorded, I have also added a few notes on species 

 that have not yet been recorded in the Irish Naturalist, 

 as also on some previous records of which the naming has 

 to be altered. 



Clubiona juvenis Simon. 



Leinster. 



Three females of this rare species were taken on the sandhills at Arklow 

 Co. Wicklow, by Mr. R. L. Pack-Beresford, in June, 191 1, and a further 

 hunt in the same locality in June, 191 3, produced several more adults 

 of both sexes and numbers of immature specimens. 



This is the first capture of this species in the British Isles ; it was 

 recorded in the Irish Naturalist of November, 1913. It is recorded by 

 M. Simon from three localities in France and from Martigny in Switzerland. 



Tegenaria pagana C.K. 



Leinster. 



Early in January, 1914, I collected some Tegenarias in an outhouse 

 at Abbotstown, Castleknock, Co. Dublin. These were apparently rather 

 large specimens of T. Derhamii, and I merely collected them for the 

 purpose of record. On examination, however, they proved to be referable 

 to the above very distinct species. Both male and female adults were 

 taken. 



T. pagana C.K. has not yet occurred in Great Britain, and its being 

 found so far only in a house makes it doubtful if it is more than an intro- 

 duced species. On the Continent it occurs in the Pyrenees, the South 

 of France and Corsica,
