OARADRINA AMBIGUA, W. V. 



A Lepidopteron new to the British Fauna, 



By Edward G. Mrek. 



While on a recent visit to Brighton I was looking over some 

 insects belonging to Mr. A. Vine, of Temple Street, in that town, 

 and found four specimens of a Caradrina so different from any other 

 British species that I obtained permission to compare them with 

 the moths of that genus in the Doubleday collection of European 

 Lei^idoptera at Betlmal G-reen Museum. On comparison I imme- 

 diately found Mr. Vine's species was identical with Caradrina 

 ambigua, in which opinion I am since confirmed. 



The anterior wings of this addition to our fauna may be 

 distinguished from any other British Caradrina by the con- 

 spicuous yellowish white margins of the reniform and orbicular 

 stigmas ; from C. hlanda by a pale yellow line edging the inner 

 portion of the cilia of the front wings. From both that species 

 and C. alsines it is also distinctly separated by the pearly white 

 under wings. The grey ground colour of the front wings reminds 

 one of C. cuhicidaris, from which, however, the other characters 

 render it quite distinct. 



Mr. Vine captured the four specimens on one evening in 

 September, 1879, at sugar, near Shoreham, Sussex. Although 

 its captor has since repeatedly sugared on the same ground, he 

 has never seen another example. 



5C, Brompton Road, London, S.W., November, 1881. 

 [Caradrina ambigua is said to occur throughout Southern 

 Europe, and not to be a common species. In our collections it 

 will be placed between C. hlanda and C. cuhicidaris. — Ed.]
