96 LEPIDOPTERA. 



from that district. Its last retreat appears to have been in 

 South Wales, where at one time it must have been common. 

 In the Tntdlifjaiccr for 1859, Mr. T. Parry, of Merthyr, 

 states : "In 1835, 1836, and 1837, I could take it in plenty, 

 but have never seen the species since." In 1874, 1875, and 

 1877, specimens in small numbers appear to have been taken 

 at Penarth, near Cardiff; and in 1871 Mr. A. B. Hudd met 

 with half a dozen near Llantrissant, Glamorganshire. Sub- 

 sequently, I wrote to Mr. Evan John, of Llantrissant, who 

 replied that he had seen in all about twenty specimens in 

 different localities, but that it unfortunately occurred only in 

 the uncut meadows, and that, as the farmers objected to having 

 the grass trodden down, the butterfly was difficult to obtain. 

 Mr. Hudd thinks that the eggs and young larvte are de- 

 stroyed in the haymaking, and probably this is the case to 

 some extent ; but hay has been made from time immemorial, 

 and some other cause must be looked for to account for the 

 disappearance of this insect. There are old records of it in 

 Worcestershu'e and Sussex, and of one specimen in Suffolk. 

 Mr. C. W. Dale appeai-s to furnish the most recent records of 

 captures. He says that twelve were taken in Glamorganshire 

 in 1876, and one in 1877 ; also that one was captured in the 

 neighbourhood of Tenby in 1883 ! This last statement is 

 somewhat startling to one who knows the neighbourhood of 

 Tenby as well as I do, and seems to require confirmation. 



Abroad, its range is extensive, comprehending great part 

 of Europe, and of the more temperate portions of Asia.
