DAN AID M. Ill 



It was stated to have been captured, in the larva state, on 

 oak, in Berkshire, in August 1869, by a young gentleman 

 whose name was given ; also that it had remained a long time 

 in pupa before producing the butterfly. This specimen was 

 aftervvards seen by the late Mr. H. Doubleday, who recognised 

 it as belonging to a variation of A. ilia of Asiatic range — not 

 European — and further pointed out that in several particulars 

 of food, time of capture, and duration of pupa state, the account 

 given was totally at variance witii the known liabits of the 

 species. No cause for suspicion appeared as to the bona fides 

 of either the captor or the gentleman who introduced it to 

 public notice at the iluseum, but it is impossible to avoid the 

 conviction that some accidental confusion had arisen with 

 regard to the specimen iu the three years between the 

 reported rearing and the date of identification. No reason 

 exists for believing this to be a British species.]
