October, 
a curious penchant for entering houses and in many cases causes great 
consternation by its entry. I heard of one case where a whole household 
save one more courageous man fled before the advent of one of these 
moths. The aforesaid man not only faced the intruder, but captured it, 
put it in a paper bag, and sent it to me ! 
Chaevocampa porcellus, L., and C. elpenor, L. — Specimens of these hand- 
some moths were sent to me in June by Mrs. Trinder. They had flown 
into the rectory at Rossnowlagh, Co. Donegal, and had been captured by 
her and very kindly sent to me. The former, according to Mr. Kane's 
Catalogue, seems to have been chiefly found in the more southern parts 
of the county. I took it here, but I do not know of any record of its 
occurrence in Donegal. 
Macroglossa bombyliformis, Esp. — I received an example of this moth 
from Wakefield Richardson, Esq., which he had taken at the Wood House, 
Bessbrook, Co. Armagh, on May 28th, 1914. He tells me that he has taken 
its congener, M. fuciformis, in Co. Louth, but as I have not seen the 
specimens I cannot vouch for the correctness of his determination, and 
as Mr. Kane says it has never been obtained in Ireland, caution is necessary. 
Hyponomeuta padi, Zell. Sta. — I was sent a nest of the larvae of this 
moth by Miss Gertrude Alexander, which she had found at Newcastle, Co. 
Down, on a tree which, as well as I could make out, was some species of 
Prunus. The larvae duly spun up and moths began to emerge on July 
12th. Along with them were a couple of species of Ichneumon flies, to 
which I hope to refer in a future communication. I have not met with 
this species before, though I have taken its congener, H. cognagellus, H., 
at Loughbrickland, Co. Down, and reared it from larvae found in Spindle- 
tree, near Tanderagee, Co. Armagh. 
Plutella cruciferarum, Zell. Sta. — Larvae of this moth occurred rather 
too plentifully on cabbage in my fields this summer. The moths began to 
emerge on July 19th. The larvae lived in little webs, and eat holes in the 
cabbage leaves. Professor Carpenter, Economic Proceedings R.D.S., 1901 
and 1907, reports attacks on this moth on turnips, to which it occasions 
great damage.

Mollusca on the Great Saltee Island. 
On June 21st, in company with some friends, and in very dry weather, 
I spent a few hours on the Greater Saltee Island. The object of our visit 
was to see the seabirds which were breeding there in great numbers, so I 
had very little time to collect mollusca, and the following' is a list of all 
I found : — Limax maximus, Agriolimax agrestis, Viirina pellucida, Hyalinia 
crystallina, Arion ater, Arion intermedius, Pyramidula rotundata, Helicella 
virgata, H. intersecta, Hygromia hispida, Helix aspersa, H. nemoralis, 
Cochlicopa lubrica, Pupa cylindracea, Limnaea pereger, L. truncatula, 
Planorbis spirorbis, Paludestrina Jenkinsi and Pisidium pusillum. The 
freshwater species, including Paludestrina Jenkinsi, were all taken in the
