TV. F. DE V. Kane — Researches at Killarneij. 593 



also suryived with their food plant here in Killarney. I spent t^wo or 

 three evenings watching the flowers, but in vain, the sudden fall of 

 temperature at sunset preventing any flight of moths ; and took only 

 two Dianthoecia cucubali, an inland as well as a coast species. I should 

 strongly suggest any future entomologist who has opportunity, to re- 

 peat the espeiiment in a more genial season. 



At the end of October I again visited the South of Ireland, spend- 

 ing a week at Cappagh, near Lismore, Co. Waterforcl. The season 

 was a very backward one, and the insects at least a fortnight late. 

 During the five days I was there I noticed nothing remarkable about 

 the entomological fauna, which did not differ to any extent from that 

 of districts in the Xorth and "W^est. I have appended a list of lepi- 

 doptera which frequent this neighbourhood. 



From the 3rd to the 9th of Is'ovember I was at Killarney, the 

 weather being fairly suitable, and I took several Cerastis spadicea, 

 and a very nice series of Zylina ornithopus and Cidaria siterata which 

 were very abundant about Mucross village. Otherwise I noticed 

 nothing remarkable about the Auturanal species, either in number or 

 rarity. 



This concludes the record of my captures of lepidoptera in this part 

 of Ireland. But at the request of ITr. Denison Roebuck, of Leeds, 

 who is engaged in the examination and comparison of Mollusca from 

 different localities of Great Britain, I collected numerous specimens 

 of this group at Killarney and elsewhere, some of which proved to be 

 of remarkable interest. 



Two examples of Limnea involuta furnished subjects for a series of 

 elaborate and careful drawiiigs, and the jaws and teeth have been 

 mounted, so that a distinct advance has been made in the know- 

 ledge of this interesting species. I shall have pleasure in laying 

 before the Academy, as a supplement to this Report, a notice with 

 which Mr. Roebuck has kindly furnished me, containing the results 

 of his study of Irish MoUusca. Among them were specimens of 

 Lehmannia arborum v. nemorosa from Killarney, establishing satis- 

 factorily, for the first time, its occurrence in Great Britain. Another 

 species of extreme rarity which I was fortunate enough to detect at 

 !Markree, Co. Sligo, Enniscoe near Crossmolina, Mayo, as well as at 

 Killarney, is Limax cinereo-niger. iSTo Irish example of this has 

 been taken in. Ireland since 1843, and only twelve altogether have 

 been found in the United Kingdom. It is very interesting to note that 

 this animal has its headquarters in Scandinavia, and its distribution is 

 distinctly northern, or confined to mountainous regions. 



A parallel instance among the Coleoptera of a boreal form occurring 

 at Killarney is noticed by WoUaston ; Pelophila borealis, a native of 

 the Orkneys : which has also been taken at Lough Neagh, and near 

 Armagh by the Rev. J. F. Johnston, and, I may add, Markree. Among 

 the Lepidoptera, besides the two northern forms previously referred to, 

 namely, Coenonympha typhon, and Toeniocampa gothica v. gothicina,
