have been recorded as taken in England— all at Freshwater in 

 the Isle of Wight— the first in 1858, the second in 1859, and 

 the third about 1876. The specimen on Plate 122, Fig. 10, was 

 received from abroad. 



Barrett's Marbled Coronet {Dianiha'cia lutcago, 

 var. barrctiii). 



The type, which is of ochrcous coloration, does not occur in the 

 British Isles, although in one example of var. barrctiii, reared 

 by Mr. Kane, a faint ochreous tinge was apparent, but this faded 

 out in a few weeks. Fig. 2, Plate 123, represents a specimen, 

 kindly lent by Mr. R. Adkin, of var. barrcttii, Doubleday, a 

 form discovered in Ireland, at Howth, by the late Mr. C. G. 

 Barrett, in June, 1861. In 1879 ^ specimen was taken on the 

 coast at Ilfracombe, North Devon ; one example was reared 

 from a caterpillar found at Tenby, South Wales, in 1884, and 

 one was captured in Carnarvonshire, North Wales, in 1897. In 

 the last mentioned year specimens were taken by the late Major 

 Ficklin on the coast of Cornwall, and as the Cornish form 

 differs from the Irish form in being grey instead of brown, it 

 has been named var. fuidini, Tutt. A second specimen was 

 obtained in North Wales in 1899. Since its first detection at 

 Howth the insect has been taken in limited numbers almost 

 every year ; and in 1906 Major C. Donovan recorded it as 

 widely distributed along the coast of Co. Cork, the specimens 

 being large, of a dark slate colour with distinct light whitish 

 grey markings. 



The caterj)illar is pale ochreous with a pinkish tinge ; the 

 central line is greyish brown and the spiracles black ; head 

 reddish brown marked with darker. It feeds on the roots of 

 seaside campion {Silciic iJiaritiuia), July to September. The 

 moth flies from June to August. Like most of the species in 

 this genus, it does not care for the collector's sugar, and except
