Some new Irlsli Crustacea. 



A '* Further Report upon the Free-swimmin;? Copepoda of the West 

 Coast of Ireland," by Mr. Isaac C. Thompson, F.Iv.S., has been recently 

 published in the Trans. Biological Soc. Liverpool (vol. xi., pp. 127-131 and 

 table). The material dealt with in this paper was collected ofFValentia 

 Island, Co. Kerry, by Messrs. Browne, Walker, and Gamble, and the 

 Misses Delap in 1896 and 1897. Several interesting forms are recorded, in- 

 cluding Rhincalanus cormitus, hitherto only known in British waters from 

 off the Shetlands. A careful table gives the exact localities and depths 

 where specimens of each species named, and indicates their comparative 

 abundance. 



The Linnean Sooieiy's Journal {Zoology) for the current year (vol. xxvi., 

 pp. 226-232, pi. 17, 18) contains an important paper by Mr. Alfred O. 

 Walker, F.L.S.. " On some new species of Edriophthalma from the Irish 

 Seas." Of the two Irish forms described as new to science ; one, Aspeudes 

 hibernicus, was taken by Mr. Gamble at Valentia Harbour, while the 

 other, Parapleustcs megacheir, was dredged at a depth of 750 fathoms off 

 our south-west coast by the Royal Irish Academy Expedition of 1888. 



INSECTS, 



Colias edusa In Ireland. 



There seems to have been quite an immigration of the Clouded- Yellow 

 Butterfly into the South of Ireland this year. When staying at Tramore, 

 Co. Waterford, in August and part of September, I found it not 

 uncommon. The weather was very bad, but on the few fine sunny days 

 with which we were favoured, if the wind were not too strong, I generally 

 saw one or more individuals daily. They seemed to prefer keeping to 

 the coast-line, chiefly the sand-hills, and the cliffs by the sea. I met 

 with but two individuals at even a very short distance inland. The 

 great majority of those I saw were males, and many of them were in 

 very poor condition, sometimes, indeed, being so rubbed and denuded of 

 scales as to be reduced almost to the condition of clear wings. I only 

 succeeded in taking a few, being generally armed with a bee-net, too 

 small for capturing butterflies. On returning to Borris, Co. Carlow, I 

 saw one there on I5tli September, and another on 23rd September. On 

 both occasions I was riding and unprovided with a net, but the last 

 individual I succeeded in capturing with my cap.
