How well one remembers the " Long time ago," with which so 

 trivial a thing as the capture of an insect, even though of no great 

 rarity, is associated. The Brown Hairstreak I first, and indeed for 

 the only time, captured, on one of two little hills with an unpleasing 

 designation in the neighbourhood of \yalliugford, Berkshire. Barnwell, 

 Ashton Wold, and the neighbourhood of Polebrook, Northamptonshire; 

 near Great Bedwyn and Sarum, Wiltshire; Coombe Wood, Birch 

 Wood, Darenth Wood, and Hornsey Wood, near London; Henfield, 

 in Essex; Raydon Wood, near Ipswich, Suffolk; Dartmoor, in Devon- 

 shire; and places in Dorsetshire and Norfolk are also given as localities 

 for it. It has also occurred near Winchester in Hampshire, Brighton 

 in Sussex, at Grange in Lancashire, and in plenty in the valley of 

 the Dovey between Machynlleth and Cemmaes; also near Cork. 



It is by no means a plentiful species, though widely distributed. 



About the end of August or the first week in September the Brown 

 Hairstreak is to be taken flying about oak and beech trees. It has 

 occurred in July. 



The caterpillar occurs at the end of May. 



It feeds on the blackthorn, birch, plum, etc. 



In this species the wings extend in width from one inch and a third 

 to rather more than one and a half. They are of a rich glossy brown 

 colour, with a short oblong mark near the middle of the front, outside 

 which is a more or less visible lighter mark, but sometimes it is 

 entirely wanting. The outside margin is elegantly bordered with white.
