82 LEPIDOPTERA. 



sitting on a stone in the same wood in 1864 it became 

 evident that the species was not exterminated ; and it was 

 again taken in 1881, though only singly. On July 15th, 1867, 

 a specimen was taken by Mr. N. Cooke in the Black Wood 

 at Rannoch, and there the larva has since been found com- 

 monly, but with little result, nearly all being infested with 

 ichneumons. Of the very few reared, some are considerably 

 smaller than Welsh examples. One such was reared by 

 Mr. R. Adkin in 1892. But Mr. W. H. B. Fletcher possesses 

 a Rannoch specimen of fully the ordinary size, and several, 

 obtained from Sutherlandshire, which are larger than any of 

 those from North Wales. The species is also said to have 

 been found in Argyleshire, and appears to be confined to 

 northern and hilly districts with us. In the present year 

 (1893) a good many have been reared from pupa3 obtained in 

 these Scottish localities, and I have myself, through Mr. 

 Fletcher's kindness, reared full-sized examples. In 1857 the 

 capture of a specimen near Ramsbury, Wilts, Avas recorded 

 by the late Mr. E. 0, Rye. If correct, this is the only known 

 instance in the south of England ; but Dr. Chapman states 

 that it has been taken near Hereford. Mr. E. Birchall was 

 of opinion that he found traces of the larva and pupa in 

 birch trunks at Killarney, Ireland, but this observation does 

 not seem to have been confirmed. 



Abroad it is found in Northern and Central Europe, 

 Piedmont, and Southern Russia.
