SOME NEW IRISH SPIDERS. 



BY D. R. PACK-BERESFORD, B.A., D.L., M.R.I. A. 



Since the publication in March, 1909, of my supplementary 

 list of the spiders of Ireland/ sixteen species have been 

 added to the list. Two of these, viz., Ero Camhridgei 

 (Kulcz.) and Tibcllus maritimus (Menge) have been up to 

 now confounded with, and recorded as, Ero furcata (Vill.) and 

 Tibcllus oblongus (Walck). I found I had specimens of 

 both the newly distinguished species in my own collection, 

 and by the kindness of Dr. R. F. Scharff I have been allowed 

 to examine the specimens preserved in the Museum in 

 Dublin, with the results recorded below. 



I have to thank Dr. A. R. Jackson for the great help 

 he has given me in determining many of the species now 

 recorded, and also Mr. R. Welch, Mr. J. N. Halbert, and 

 Mr. R. J. Pack -Beres ford and Miss M. Browne-Clayton 

 for collections sent me. Several of the species here noted 

 were taken by Mr. H. Wallis Kew in Co. Cork and Co. 

 Kerry, and have been recorded by him.^

 Leinster. 



A single female was taken on the Howth clifts in igog by Mr. J. N. 

 Halbert, and was kindly identified for me by Dr. A. R. Jackson. On 

 searching the same locality again in company with Mr. Halbert we fonnd 

 several immature specimens in Octobi^r, 1910. 



In Great Britain this spider is described by Mr. Cambridge as being 

 very local, and has been taken only in Gloucestershire, Wiltshire, and 

 Dorset. 



On the Continent it is recorded from six or seven places in France, and 

 is said by Mr. Simon to be ' assez rare." Ft is also found in Hungary.
