vary appreciably, except in the series of white streaks on the 

 under side of hind wing, which in most Irish specimens are 

 wanting, wholly or in part ; often represented only by a single 

 one on the costa. Occasional in Co. Dublin ; in Co. Wicklow at 

 Powerscourt, Tinahely, not scarce (Biv.) ; Westmeath, abundant 

 on the bogs at Cromlyn {Mrs. B.) and Killynon {Miss R.) ; in 

 King's Co. at Tullamore and Toberdaly, abundant ; rare at Sligo 

 and Markree ; abundant at Cappagh, Co. Waterford ; common in 

 many places in Co. Cork, Bandon ; and very abundant at Glen- 

 garriff, Killarney, Bere Island, and Kerry, generally ; Galway, 

 abundant ; Limerick (A'^.) near Crossmolina, Co. Mayo. 



PoLYOMMATus PHLCEAS, L. — Occurs throughout Ireland, but 

 not, I think, in large numbers in the northern counties. I have 

 noticed the late brood in Ards, North Donegal, in Sept. — Oct. I 

 have an Irish specimen with the orange bleached to a straw 

 colour, approaching var. schmidtii, taken near Favour Eoyal, Co. 

 Tyrone ; and another with a similar colour on one fore wing, 

 otherwise normal. The ordinary variations, with broad hind 

 marginal black bands and large spots, and more or less blue 

 spots on orange band of hind wing, occur. 



LvciENA ^GON, Schiff. — *' The Murrough of Wicklow, and 

 near Eostrevor " {B.). 



Ltc^na ICARUS, Rott. — Some years ago I was so much struck 

 by the unusual characters presented by Irish specimens of this 

 species, the brilliant female of which I referred to in 1885 

 (' Handbook of European Butterflies '), that I was preparing to 

 publish a notice on the Irish forms of icarus ; but, fortunately, 

 in January, 1887, Mr. South commenced a series of articles on 

 the genus Lyccena, and, with the abundant materials at his dis- 

 posal, was able to deal with the subject much more thoroughly 

 than I could have done, illustrating his remarks by comparison 

 with various English and Scotch varieties. The monograph 

 dealing with L. icarus, appearing in vol. xx., p. 73, of the 

 'Entomologist,' and accompanied by a coloured plate (pi. ii.), 

 will obviate the necessity of my doing more than refer to the 

 descriptions there very fully given. In the first place, the Irish 

 butterfly usually considerably exceeds in size that of England, 

 varying from about 1 inch 2 lines to l^- inches in the June 

 emergence ; but the individuals of the second emergence are 

 much smaller, and generally conform much more nearly to the 

 usual English type in both sexes, to which, therefore, I need not 

 further refer. Probably referable to var. ipusillus, Gerhard 

 (c/. Dale's ' British Butterflies '). Mr. South notes that the Irish 

 and Scotch icarus are similarly characterised by their large size, 

 and the brilliant blue of the female bordered with bright orange 

 marginal ocelli. The chief aberrations observed in the male are 

 as follows : — 1. The colour approaching that of L. bellargus
