108 OCCASIONAL PAPERS. 



ance of some late but very fresh specimens in 

 October led entomologists to conclude that there were 

 two broods. It was not, however, till last year that 

 any evidence was obtained proving that their might 

 be in some years three. Nowhere was this proved 

 more satisfactorily than in Folkestone, by one of our 

 own members, Mr. Blackall, who has kindly placed 

 at my disposal notes of his observations on the insect 

 throughout last summer. The first appearance was 

 in June, abnormally early. On the 9th of that 

 month as I was in a field by Lady Wood, a specimen 

 of Edusa rushed by me in its well-known headlong 

 manner. Those who have ever hunted it know what 

 a chase it is. The day was hot, I did not want to 

 run about, and like the fox in the fable, though I 

 should have liked to capture it, I said to myself "It 

 is but a hybernated specimen." Please give me the 

 credit, however, which we do not award to the afore- 

 said fox, of believing what I said to be true. Presently 

 a second flew by, then a third, and a fourth. I 

 caught the seventh, which was in such good condition 

 that I determined to have as many as I could get. 

 Of course after that determination I saw no more. 

 On mentioning this to Mr. Blackall, I found that he 

 having more opportunities than myself, had already 

 taken some specimens, the first being captured June

 next morning, but only saw one. Within the next 

 few days dozens might have been taken ; many in 

 perfect condition ; one, in fact had its wings still 

 limp. There was therefore no doubt about their 

 being freshly emerged specimens ; probably none 

 had hybernated. Some of these were of unusually
