174 T^^^^ Irish Nahiralist. October, 



classified as a single species, I went throu,i,'h all the specimens I liave in 

 my collection and was also permitted by V^w SchariT to examine all tlusc 

 in the Mnsenm. As a result I lind that both species were present. This 

 species has been taken at Woodford, Co. Galway (R. Li. Praeger. July, 

 IOCS). Portmarnock. North Bull, and Terenure, Co. Dublin ; and Bundoran 

 and Cdenveigh. ("o. Donegal (R. Welch, Julv. 1910). 



There are also in the IMuscnun collection several immature specimens 

 froni various localities, which it is impossible to refer detiuitelv to eitiier 

 species. 



Tibellus maritimus (Mengr) 

 T. cihlongus. Sim. — Ar. de France. T. obln)i<;iis. Kulcz. — .\r. Hung. 



LkINSTER. CoXNAlUillT. 



This spec'cs has been taken at Fenagh, Co. Carlow ; Tullamore, K'ing's 

 Co. ; and Mote Park, Co. Roscommon. 



The nomenclature of these two s]iecies as may l)e noted is decidedly 

 inappropriate, for wliereas ]ii:in'liiiiiis has been taken onlv in inland 

 localities, nearly all the sjiceimens of T. (^hlinii^iis are from places on or 

 near the coast. 



Hahnia nava (Bl.). 

 Ulster. Leinster. 



.\ single female of this sjiecies was taken at Ballyconnel, Co. Ca\-an. 



in April-May, iqio, by my brother, Mr. R. J. Pack Beresford, and two adult 



pairs were taken on Ireland's Eye in October, iQio, by Miss M. Browne 



Clayton. It ranges all over Oreat Britain from Dorsi't to ICdiubiugii. while 



on the Continent it has been taken in Swe^len, Cieiniany. Austria, 



Hungary, France and Corsica. 



Ero Cambrldgei, Kidcz. 

 Thcridion "i^ariraatitm. Bl. Spid. Ci.B.I.? liyti finrn/a. (N'ill.) in part. 



I.EINSTER. 



Professor Kulczynski has also discovered that we liave ha<l two 

 species of Ero in our collections, both of which have been includcil in the 

 species En^ fufidla, \'ill.. and he has described and named one of them 

 as above. I found that I had both in my collection taken at 

 Fenagh, Co. Carlow. This species seems to me to resend)le very closely 

 the figures of Thcridion varie^atutn given by Blackwall in his " Spiders 

 of Great Britain and Ireland," and I tJierefore, give this name as a 

 synonym tentatively, as of course without comparing the actual specimens 

 described by Blackwall. it is impossible to speak witli certainty as to 

 their identity. 



Professor Eulczynslci has idi'utiliei! specimens from Dorset, luigland, 

 as belonging to this species, and also from Cracow. 



Ero f areata (\ill.). 

 Ulster. Munster. Leinster. 



An examination of the spiders in the collection in the Dublin ^hlseum, 

 under this name, shows that two females were taken in Londonderry
