SOME NEW AND RARE IRISH SPIDERS. 



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



Since the publication in the Irish Naturalist of my last 

 list of new and rare Irish Spiders, in April, 1920, I have 

 only one new to the Irish list to record, but that is of special 

 interest as being new. to science. I sent it to the late 

 Rev. O. P. Cambridge shortly after taking it, but he did 

 not publish his description of it till three years later, when 

 it escaped my notice, and hence the dela^/ in recording it 

 in the Irish Naturalist. The species is Maso persimilis Cb. 

 and further particulars are given below. The other species 

 now recorded have all been taken previously in Ireland, 

 but at most in two or three localities, so that these further 

 finds are of interest. I have to thank Mr. R. A. Phillips 

 and Mr. H. B. Cott for collections they have made for me 

 in various localities, from which many of the following 

 records have been taken. 



Maso persimilis O. P. Cambridge. 

 Leinster. 



In December, 1909, I sent a very minute but very distinct female 

 spider, taken at Fenagh, Co, Carlow, to Mr. Cambridge, which at the time 

 he was unable to indentify and which he afterwards described as a new 

 species under the above name. His description and figures were pub- 

 lished in the Proceedings of the Dorset Natural History and Antiquarian 

 Field Club, vol. xxxiii., pp. 77 and 91, 1912. Mr Cambridge was rather 

 doubtful whether to place this spider in the genus Maso or in the closely 

 allied genus Gongylidiellum, Simon. 



Hahnia helveola E. Sim. 

 Ulster. 



Amongst a lot of spiders collected by the late Mr. J. R. Milne, in the 

 County Londonderry, which had been in the National Museum for some 

 years awaiting identification, I found a single female of this species, which 

 had previously only been found in Co. Dublin, at Howth and Malahide. 

 These finds I recorded in the Irish Naturalist in vol. xxix., p. 30. 



Hahnia nava Bl. 



CONNAUGHT. 



I recorded the first occurrences of this species in the Irish Naturalist, 

 vol. XX., p. 194, from Ireland's Eye and Co. Cavan. Mr. R. A. Phillips 

 has now sent me two females from Spanish Point, Co. Clare, taken by 

 himself in February, 1921.
