considerable height, with a south-west exposure, in veins of shale which 

 run through the limestone. It attained considerable luxuriance. This 

 is the most northern locality known for the plant in Ireland. 



The meeting then adjourned to the month of January, 1857. 



After the ballot, the following were declared duly elected as Ordi- 

 nary Members : — Arthur Mitchell, M. D. ; John Hamilton, Esq. 



FRIDAY EVENING, JANUARY 28, 1867. 



Rev. Samuel Hauohton, F.T.C.D., M.R.I.A., in the Chair. 



The Minutes of previous meeting were read and confirmed. 



Mr. "W. Andrews took the opportunity to correct a mistake which 

 had crept into the report of a paper read by him at the meeting of the 

 Society in June last, on the occurrence of the brown hairstreak (Theela 

 hetuke) in Kerry. By some inadvertence he had been stated to have 

 only observed one specimen, whereas, on the contrary, this insect was 

 just as abundant in that locality as the brimstone butterfly ( Gonepteryx 

 rhamni). The hairstreak being considered a very rare insect in Ireland, 

 he thought it advisable to correct this error. 



Mb. R. p. "Williams then read a paper — 



ON the occtjhrence of colias edusa in the county op wateefoad. 



I HAVE the pleasure of bringing before the notice of the Society, this 

 evening, specimens of one of the rarest of Irish butterflies, which I have 

 only seen recorded as such in the recent work of the Rev. F. 0. Morris, 

 on ** British Butterflies," wherein he states that, on the 9th of Septem- 

 ber, 1844, two were seen, and one captured, by Mr. Joseph Poole, of 

 Grovetown, near Wexford. A much earlier instance (the precise time 

 of which I cannot supply, but certainly as early as 1820), however, oc- 

 curred, when Mr. Tardy was forming his collection — afterwards increased 

 by numerous additions, and class^ed by the late Dr. Thomas Coulter, 

 Mr. Tardy having died ere he completed his task. This collection may 

 now be seen in the Museum of Trinity College. Enthusiastic, however, 

 as Mr. Tardy was, I believe he was not able to secure an Irish specimen, 

 although two or three English, and marked as such, are in the collection. 

 A co-labourer in the field, the late Mr. Cooper Haffield, was more 

 fortunate. He was, at least, blessed with a sight of the insect, though 

 not doomed to be fortunate in capturing it. He is reported to have 

 chased it for a distance of three miles, when it fairly baffled him by 

 taking out to sea between "Wicklow and Arklow Head. On return from 

 his excursion, Mr. Haffield was so excited by the chase, and by the 

 recollection of the insect vividly existing in his imagination, that, to 

 record the fact, he at once set to work, and made a fac-simile of the 

 butterfly he was not destined to capture. This he placed in his cabinet, 

 and it has been passed over many a time by inquisitive eyes without 

 detection, and duly acknowledged an Irish specimen. I had often heard 

 that story very amusingly told, but with some degree of scepticism, until
