mens for us, also to Mr. W. F. de V. Kane. The advice we 

 received from him from time to time greatly helped us ; the 

 interest he took in our captures, and his unfailing kindness in 

 identifying specimens stimulated our ardour for further in- 

 vestigation. 



RHOPAIvOCERA. 



The butterflies we found form a small company. The number of 

 species is only about half of that in Mr. Birchall's list of 1868. Many of 

 the absent species should occur here, and probably on further investiga. 

 tion will be found. The beautifully- situated, warm, sheltered woodland 

 about Rathmullan, on the Lough Swilly shore, must harbour many 

 butterflies, and should yield some interesting kinds. 



Picris brassicae, Linn.'j 



P. rapac, Linn. j- All very common. 



P. napi, Linn, J 



Euchloe card amines, Linn. — Fairly common. 



Colias cdusa, Fab. — This beautful butterfly appeared here in some 

 numbers in 1876. We had never seen the species before, and I have 

 never noticed it in this district since; I find the dates of capture in 

 our note-book, 27th June, 15th July, and 9th September, 1876. 



Argynnis paphia, Linn. — Not very common, but to be met with in 

 almost all wooded localities. In 1879, I noticed it in some profusion 

 in the glades of the beautiful woods of Ards, near Dunfanaghy. 



A. aglaia, Linn. — Common on the coast. 



Vanessa urticae, Linn. — Common everywhere. 



V. io, Linn.— We never found this richly-marked species, but Mr. Wni. 

 Hart took it in Innishowen, and Mr. John Cowie reports its occur- 

 rence near Derry many years ago. 



V. atalanta, Linn. — Not abundant, but in every district. 



V. cardui, Linn. — We took a few specimens only of this pretty, cosmo- 

 politan insect every season. In 1880 and 1884, however, it was very 

 abundant. 



Pararge egeria, Linn. \ 



_ ^ . \ Very common. 



P. megaera, Lmn. ) "^ 



Satyrus semele, Linn. — Common on the coast. Mr. Milne reports 

 having seen this butterfly sivarming at Castlerock, between 4 and 5 

 a.m., on an August morning, although throughout the day only a 

 small number, comparatively speaking, were seen. 



Epinephile Janira, Linn. — Very common. 



E. hyperanthcs, Linn.— Rare and local in this district. We found it 

 abundant at Ballymoney, Co. Antrim. 



Coenonympha pamphilus, Linn.— Common. 



C. tyption, Rott. — I met this species for the first time, on 22nd July, 

 1892, on the moors between Gartan and Glenveagh, Co. Donegal, 

 and again at L. Salt, on 23rd July. The specimen I secured is 

 similar to the English variety of the insect {rothlicbii). 



Polyommatus phlasas, Linn— Common. 



Lycaena icarus, Rott.— Found everywhere, but especially abundant 

 upon the coast.
