368 LEPIDOPTERA. 



with the spurs also long, rich chestnut with long white 

 intervals. Female similar. 



Underside of the fore wings dull red-brown, the white 

 stripes on the lobes very distinct but somewhat curtailed. 

 Hind wings as above, except that in the middle there is a 

 dull white dot, and at the apex of the anterior lobe a white 

 horizontal streak. Body golden-brown with parallel rows of 

 white streaks. 



Larva green or dirty yellow, with short knobbed raised 

 dots, and long white hairs ; on the hinder segments is a 

 double row of redder or browner longitudinal streaks ; head 

 honey-yellow. Lives in the heart-shoots of Hieradum, um- 

 bcllahim, sociably. (Frey.) 



Pupa light green with brown triangular markings on the 

 back. (Frey.) 



A good deal of mystery hangs over this species in this 

 country, and I venture to include it as British with some 

 misgivings. Thei-e are specimens in the collection of the late 

 Mr. T. H. Allis in the Museum at Newcastle-on-Tyne which I 

 believe to be correct, but unfortunately the locality in which 

 they were taken is not now known. Mr. Stainton included it 

 without doubt in his "Manual," and there gave Birkenhead, 

 Bristol, Darlington, and Newcastle-on-Tyne as localities ; and 

 for anything that I know it may still exist in some of these 

 more northern localities, or on the other hand they may refer 

 to 0. teucrii, which at the date of that work had not been 

 separated as a distinct species. Unfortunately all the more 

 modern supposed examples which have come under my notice 

 have proved to belong to other species ; and frequent and pro- 

 longed search among the food-plant has furnished no satis- 

 factory result. At present, therefore, I can furnish no certain 

 locality in these Islands. Abroad it seems to be well known, 

 and found through Central and Southern Europe, Finland. 

 Livonia, and Armenia.
