Leucophasia sinapis in Co. Cork. 



I took a few specimens of the Wood White [Leucophasia sin apis) in 

 some marshy ground bordered by trees near Mallow, not far from the 

 Railway Station, on the afternoon of May 30th whilst waiting for the 

 train to bring me on to Killarney. I believe this butterfly is not only 

 new to Mallow but has not been hitherto recorded from Co. Cork, though 

 doubtless it will turn up in other parts of the county when looked for. 

 That it should have so long escaped notice only proves, alas ! the want 

 of observers.

Leucophasia sinapis in Co. Wicklow. 



On May 27th I took a fine male L. sinapis on a hedge dividing a lower 

 spur of the Great Sugar-loaf Mountain from Kilmacanogue marsh. On 

 May 28th I took another, also a male, along the hedge dividing 

 Kilmacanogue marsh from the main road leading to the Glen of 

 the Downs. The nearest wood — and one usually associates woods 

 with this species — is The Quill about half a mile distant ; this I have 

 searched for further trace without result as yet. I can find no previous 

 record of this rather local insect in the Dublin district.

Pisidium parvulum in Co. Antrim. 



On the occasion of the Belfast Naturalists' Field Club excursion to 

 Moira and the Broadwater in May last, I dredged the canal for mollusca 

 and was surprised upon working through my material at home to find that 

 Pisidium parvulum was one of the commonest representatives of the 

 genus. Since Mr. R. A. Phillips first recorded this little species as fossil 

 from Ireland {Irish Naturalist, vol. xxv., 1916, p. loi) he has discovered 

 it living only in the River Suck near Ballinasloe, Co. Galwa5^ Having 

 failed to find it in the Lough Neagh basin I had come to regard it as 

 almost certainly absent from N.E. Ireland ; its abundance in the deeper 

 parts of the canal between Moira station and Aghalee is therefore rather 

 curious. The molluscan fauna of the canal at this point, its head waters, 

 is as follows : — Limnaea stagnalis, L. auricularia var. acuta, L. pereger, 

 Physa fontinalis, Planorbis carinatus, PL alhus, PL glaber, PL fontanus, 

 Valvata piscinalis, V. cristata, Bithynia tentaculata, Anodonta cygnsa, 

 Sphaerium corneum, Sph. lacustre, Pisidium subtruncaturn, P. parvulum, 

 P. nitidum, P. milium, P. amnicum, P. casertanum, P. henslowanum, 

 P. pulchellum, and P. hibernicum. I have listed the Pisidia in the order 

 of frequency of occurrence in the dredgings. I have considerable doubt 

 as to whether the species here referred to is the Pisidium parvulum of 

 Clessin and Westerlund, as the only two sets of shells so named that 1
