Polyommatus Phlaeas. — Common. 



Lycaena ^Egon. — The Murrough of Wicklow, and near Bostrevor. 



„ Agestis: — Dundrum, near Dublin, Wicklow and Mourne Moun- 

 tains. 

 ,, Alexis. — Common everywhere. 



,, Corydon. — Mr. Greene inserts this species on Mr. Hely's au- 

 thority. I have not met with it. 

 ,, Alsus. — Very common in Galway; also occurs near Belfast, 



and on the Portmarnock sand hills. 

 ,, Argiolus. — Generally abundant throughout Ireland, where the 

 holly, on which the larva feeds, is a very common tree. 

 Nemeobius Lueina. — In Mr. Tardy' s Collection, now incorporated with 

 that of Trinity College, Dublin, there are specimens of this 

 insect, but I am unable to say where captured ; most pro- 

 bably in the county of Wicklow, a district he searched assi- 

 duously for many years. I have not met with the insect. 

 Thanaos Tages. — Hitherto only noticed near Galway. 

 Hesperia Sylvanus. — The Murrough of Wicklow.

It thus appears that only forty-three of the sixty- four British But- 

 terflies have been observed in Ireland ; the twenty-one absentees may 

 be thus classified, following the divisions of Mr. H. C. Watson's " Cy- 

 bele Britannica" : —

all three will eventually be found in Ireland, especially as 



they occur in Scotland, from whence Ireland seems to a 



large extent to have derived its insect population. 



Thecla W. Album. ^ Pive species of the " English Type." None of
