SEKICORlD.^:^SEKICOJUS. 55 



silvery lines at the margins of the markings on the fore 

 wings are usually very much more distinct, while in many of 

 our specimens hardly a trace of them is to be seen. 

 On the wing in June and July. 



Larva ajjparently undescribed. Sorhagen says that it is 

 to be found in May and June on whortleberry. 



This species has long been known with us under the name 

 of S. daleana — apparently a mere catalogue name and un- 

 connected with any description — and it was only by the 

 discovery in a large collection of specimens which, as 

 varieties, coincided with Continental forms, that its identity 

 was here established. It is common — sometimes abundant 

 —in Scottish mountain districts, frequenting bushy places 

 on the borders of highland woods and glens and the open 

 parts of the woods, among whortleberry, from which it is 

 readily disturbed in the daytime, Hying in every direction 

 from the footstep and appearing in the afternoon as though 

 on the wing of its own accord. This, however, really takes 

 place more toward sunset and till dusk. Although common 

 in such spots on the lower hills and glens, it is extremely 

 local with us, and seems at present to be known only in 

 Perthshire and Aberdeenshire though one would expect to 

 find it in other mountain districts in Scotland. No record is 

 known to me in England, Wales, or Ireland. Abroad it is 

 found in Norway and Sweden, Germany, Galicia, Jutland, 

 Russia, Siberia, and Tartary. 



4. S. lacunana, ,SV-A/^— Expanse | to f inch (15-19 mm.).

 band nearly divided by a straight whitish streak. 



Antennte black-brown, dotted \vith white ; palpi and head 

 olive brown ; thorax black mixed with olive-brown ; abdomen
