228 LEPIDOPTERA. 



also in pods of Vicia cracca, Lathyrns pratcnsis, and 

 Z. iKikistris. 



Pupa rather slender ; wing and limb-covers very glossy ; 

 abdomen less so, each segment banded with a fine series of 

 minute teeth, and a ridge following it ; cremaster short, 

 rounded, and furnished with a strong tuft of hooked bristles ; 

 chestnut colour. 



The moth flies swiftly and wildly in the afternoon 

 sunshine, from four o'clock onwards, over its food-plant, and 

 is so swift as to be said to be difficult to capture. It certainly 

 iiies again at night, since it has been captured, in both sexes, 

 at a strong light, late at night in Wicken Fen. A very local 

 species, originally found on the coast cliffs of Yorkshire near 

 Scarborough — where it seems to have long been known before 

 it was published as a British species. Since found also in the 

 fens of Cambridgeshire, and in Norfolk and Dorset; but so 

 far as I know, not elsewhere in the British Isles. Abroad 

 it seems to be found all over the Continent of Europe, and 

 in Asia Minor.
