Potamojafeton panormitanus in Ireland. 



In a note in the journal of Botany for October, 1919 (p. 285) 

 Mr. Arthur Bennett writes : "I also find specimens of P. panormitanus 

 Biv., from Ireland as " P. pusillus L., var. teniiissimus Koch., off Harbour 

 Island, Lough Ncagh, Co. Antrim, 10 Aug., 1909, C. H. Waddell. It 

 is probably fairly distributed in this country but all specimens need 

 examination as to whether they are this or pusillus." 



Tolypella glomerata var. erythrocarpa. 



This variety is described as new by J. Groves and G. R. Bullock- 

 Webster in the Journal of Botany for August, 1919, from one locality in 

 Anglesey, and two in Ireland — Lough Melvin in Leitrim (R. LI. Praeger), 

 and Lough Magheradrumman in E. Donegal (G. R. Bullock- Webster). 



ZOOLOGY. 

 Leucophasia sinapis in Co. Wexford. 



On May 30th I took a fresh-looking male of the Wood White butterfly 

 in a wooded glen called Tubbergall, which forms part of the boundary 

 between BaUyhyland and Caim. I believe this is the first recorded occur- 

 rence of the species in Co. Wexford. I am much interested on finding from 

 Mr. Bonaparte-Wyse's and Mr. Tebb's notes in the July number {supra, 

 p. 92) that the insect has also been added this season to the faunas of 

 Co, Cork and Co. Wicklow, and not only so, but also very nearly on the 

 same date in all three cases — Mr. Tebb taking his two specimens (both 

 males) on May 27th and 28th, while Mr. Bonaparte-Wyse's first capture 

 was made on the 30th and mine on the same day. I can hardly think it a 

 mere coincidence that the same butterfly should have turned up for the 

 first time in three different counties (all in the southern half of Ireland) 

 in the course of the same week. Its not having been noted previously 

 in Co. Cork is attributed by Mr. Bonaparte- Wyse solely to " want of 

 observers," but I had been attending to the butterflies of the BaUyhyland 

 district for more than forty years before I saw my first example of 

 Leucophasia sinapis, in a piece of ground that had always been one of my 

 favourite hunting resorts ; and though it was so fresh a specimen that it 

 is hard to imagine it had flown far. I find it equally hard to believe that 

 a species so long looked for in vain had all the time been a resident only 

 half a mile from this house. The simultaneous capture made in two other 

 localities so far apart as Mallow and Kilmacanogue add much strength 

 to the suspicion that a sudden irruption of this butterfly must have taken 

 place.
