144 THE BUTTERFLIES OF THE BRITISH ISLES. 



specimens had been taken in Yorkshire, but this was only a 

 ruse, as T. pruni has never occurred in that county. It is 

 confined, so far as Britain is concerned, to three or four of the 

 midland counties. " Mr. Herbert Goss, who has found it at 

 Barnwell Wold, and in other wooded districts of Northampton- 

 shire, at intervals, for more than twenty years past, says that it 

 is fond of sitting on the flowers of privet (Ligustrum), and of 

 Viburnum lantana, in the woods, and sometimes is to be 

 found in numbers. Its time of emergence is very variable, 

 apparently regulated by the lateness of the spring — from 

 June 17th to the first week in July. Reared specimens made 

 their appearance from June 13th to 27th. He writes, ' It was 

 the greatest possible pleasure to see them walking about the 

 table while I was at breakfast. 5 In 1858 it was found commonly 

 at Kettering, and in 1859 at Oundle, and has been recorded at 

 Warboys Wood, Huntingdonshire, and in Buckinghamshire. 

 One specimen was taken at Brandeston, Suffolk, by the Rev. 

 Joseph Green ; and Mr. Allis found it commonly in the Overton 

 Woods and about St. Ives. There is also a record in Mon- 

 mouthshire, which may require confirmation. This butterfly 

 does not appear to be losing ground in this country, its fondness 

 for trees and lofty bushes rendering it difficult to capture" 

 (Barrett). 



A writer in the Entomologist for 1874 mentions Linford 

 Woods, in Bucks, as a locality where he had observed several 

 specimens, mostly females, on flowers of privet. 



It is found throughout the greater part of Europe and also in 

 Amurland and Corea. 



The White Letter Hairstreak (Theda w-album). 



The male of this butterfly (Plate 94) is blackish, with a small 

 whitish sex mark at end of the discal cell of the fore wing ; there 

 is a small orange spot at the anal angle of the hind wings. The
