244 PROCEEDINGS OF SOCIETIES. 



From which comparison it appears, that of the " Rhopalocera* 1 we possess 

 nearly two-thirds ; of the " Heterocera," a little more than half; of the " Bora- 

 byces,'' nearly two-thirds; of the " Noctuae," somewhat under one-half ; of the 

 " Pyrales," little more than one- third ; of the " Geometrae," rather more than one- 

 half. 



This is, undoubtedly, in some respects, a meagre list, but I feel confident that 

 there are yet many species in Ireland, waiting only the zeal of active and per- 

 severing entomologists. In proof of this, I may mention, that by digging alone 

 for pupae, in the neighbourhood of Dublin, during the past winter months, I have 

 been enabled to add to the list, the following 11 species, which, according to the in- 

 formation I have received, have not yet been taken in Ireland, viz. : — Orgyia pudi- 

 bunda, Cerura bifida, Notodonta trepida, Acronycta megacephala, Ceropacha ocu- 

 laris, Cosmia affinis (Powerscourt), Xylophasia hepatica, Chariptera aprilina, 

 Eupithecia castigaria, Eupithecia piperaria, and Exiguaria.* Mr. Haliday, it is 

 true, has marked M Chariptera aprilina" in his list, but with doubt. I have found 

 the empty pupae in some plenty, at the roots of oak, near the Viceregal Lodge, 

 Phoenix Park. 



I propose, on some future occasion, to draw up a few remarks (intended solely 

 for beginners, or inexperienced entomologists) as to the most likely localities for 

 insects, the best modes of capture, &c. ; considering that, for want of such infor- 

 mation, many are deterred from commencing the pursuit at all, while others, who 

 have commenced, grow disheartened from want of success, and forthwith cease to 

 collect. 



Where Kingstown, R/athfarnham, or Powerscourt are mentioned as localities, the 

 insects have been taken by myself. 



Mr. Haliday observed, that the list just finished, reflected a great deal of credit 

 on the persevering diligence of Mr. Greene ; the labour of making such a list was 

 known only to those who made the attempt. With regard to the vast disproportion 

 of species between this country and England, he thought, with Mr. Greene, that, by 

 industry of collectors, it might be greatly lessened. Mr. Haliday also exhibited some 

 of the rarer Irish insects, and mentioned the supposed localities for them, in order 

 that if these spots were visited, in the course of the ensuing vacation, by any of the 

 younger members of the association, they might be aware of what to find at them. 



Mr. E. P. Wright read the following catalogue, by the Rev. Aiken Irvine: — 



CATALOGUE OF ZOOPHYTES FOUND IN DUBLIN BAY AND IN ITS VICINITY. 



The notes from which the following catalogue was drawn up were made during 

 the years 1849-50, and the spring of 1851 ; and though I feel it, in many respects, 

 is a most imperfect one, I am induced to offer it to the members of the Dublin 

 University Zoological Association, with the hope of inducing some of them to draw 

 up a more perfect list of those found in the district which it includes. 



I have purposely refrained from any observations on the Zoophytes contained in 

 it, as it is my intention, at a future period, to lay before the Association some 

 remarks on the Irish Zoophytes and their geographical distribution ; and, with this 

 view, I will be glad to receive from any member of the Association notes on those 

 which may observed by them round the coasts of Ireland. 



The nomenclature I have adopted is that used by Dr. Johnston, in the second 

 edition of his very classic Monograph of the British Zoophytes, which, I feel 

 confident, is the most generally adopted ; while in the cases in which it differs from 

 that I have followed, the list drawn up by Mr. Gray of the collection in the British 

 Museum, I have added the name adopted by him within brackets — thus [ ].

 Eupithecia pulchellaria, and Eupithecia nauaria. — J. G.
