Note on the seasons of appearance of Polyommatus Argiolus in Suffolk. Should the following note on the seasons of appearance of Polyommatus Argiolus in Suffolk be deemed of sufficient interest for the pages of 'The Zoologist,' it is at your service. On referring to my register I find that the first specimen of this butterfly I ever possessed (a male), was captured at Kedington on the 9th of May, 1833, and was the only one obtained that year. In 1834 one was taken on the 31st of July, and others on the 1st, 8th, and 12th of August. In 1835 the dates of capture are May 8th, 16th and 19th, June 6th, July 23rd, 27th and 30th, August 1st and 6th: on the 19th of May and the 6th of August it was very abundant. In 1836 I took a male at Lavenham on the 7th of May, which is the earliest date I ever saw it, and as it continued very abundant in the same locality during the whole of that month, I much regret that I did not take more than a supply for my own cabinet, as it has been a very rare insect ever since, and appears now to have wholly disappeared. The two specimens before noticed (Zool. 172) are the last I have seen.— W. Gaze; Ballingdon, Sudbury, Suffolk, July 17, 1843.
Note on the occurrence of Colias Edusa. Judging from Mr. Jordan's remarks (Zool. 176) I presume it may not be wholly without interest, at least to that gentleman, if I state that Colias Edusa was common in the Isle of Wight in the year 1804. It was
