THE ENTOM()LO(JlST S RECORD. 



similar plant. We tried two or three clover fields at Eastbourne 

 but saw none in them at any time. Lucerne in the Eastbourne 

 district is conspicuous by its absence, but I found one field and with 

 the exception of one stray worn ^ no C. ednsa were seen it it. 



Mr. Sharp took two var. lielUr, and I took one. Two of these we 

 kept for ova, Mr. Sharp undertaking the rearing. From the helice ova. 

 he bred 31 J s, five 9 s, and eight var. helice. From ova laid by a 

 typical J he bred 71 J" s, 46 $ s, but no var, helice, all of which I exhibited 

 on his behalf at the South London Natural History Society's Variety 

 Exhibition in November last. 



On August 31st I went to Margate, and on September 2nd, in an 

 interval of sunshine, took three c^s and IjC edii.sa, all worn. I 

 released the former and kept the latter for ova. 



On September 5th I had arranged to meet Commander Gwatkin- 

 Williams, who was staying at Broadstairs and had found an "emerging" 

 field. We cycled to it, and immediately on our arrival rain began to 

 fall, and came on so badly that we were kept prisoners in a barn for 

 two hours, after which we cj^cled home and got thoroughly drenched. 



On September 7th I again met Commander Gwatkin- Williams 

 at this field. I had just fixed up my net and was getting some pill- 

 boxes from my satchel when a butterfly flew quite close to my face, 

 and as it went by I noticed it was var. helice. A short chase and I had 

 it in my net. It proved to be a freshly emerged specimen, a piece or 

 good luck, as Commander Gwatkin- Williams had been on the look- 

 out for the variety for three weeks previously without seeing one. I 

 took another on the last day of my stay, these being the only two seen. 

 A north-east gale was blowing, but we managed to take between us 

 during the morning nineteenths and two $ s besides the var. helice. 

 The two ? s and two of the ^ s were freshly emerged, the remainder 

 good, bad and indifferent. Those not worth setting were released with 

 the exception of some that had single notches in one wing, which I set 

 for reference in connection with the attacks by birds theory ; not a 

 single specimen was found during my stay with more than one 

 wing notched. Swallows were flying up and down the sheltered 

 side of a hedge all day, where also Pohjonnnatus icarus and other 

 butterflies were enjoying the shelter and sunshine. I paid particular 

 attention during my stay, but never once saw a swallow attack a 

 " blue " much less an edusa, and Commander Gwatlun-Williams's 

 experience was the same. ( '. edtisa, g s and ? s, continued to emerge 

 daily up to September 15th the last day on which I visited the field. 

 Both were most variable, the S s in size (some were twice the size of 

 others), and also in width of black marginal bands, etc., the 2 s in 

 size of yellow spots in the black marginal band, one specimen being 

 referable to var. obsoleta. On one morning we took between us 35 

 specimens. 



Some of the lucerne fields I visited in Thanet had quite a number 

 of (? s in them, all worn, and which made the fields a playing ground, 

 circling round them, engaging in mock combats, occasionally settling 

 on a flower for an instant only, and were no doubt wanderers from the 

 true emerging field. On September 9th I cycled down to Dover and 

 came across a collector who had been taking C. ediisa S s freely in a 

 field there for three weeks, during which time he had not taken a 

 freshly emerged specimen, nor had he seen a single 2 , which to him
