108 BRITISH BUTTERFLIES. 



V 



sonal observation, is quoted from a communication to 

 the Intelligencer, by a well-known entomologist, Mr. E. 

 S. Edleston, of Manchester. He says : 



"I and my friend, Mr. Hugh Harrison, in the 

 middle of June made the ascent to Sty Head Tarn ; for 

 the first time in my experience, the weather was every- 

 thing we could desire calm and sunshine ; this, com- 

 bined with the dry season of last year and the long 

 drought for months during this, enabled us to collect on 

 ground in other years a dangerous morass. The result 

 was, we captured Cassiope in abundance, some of them 

 in superb condition, just emerged from the chrysalis. 

 A very short time on the wing suffices to injure them. 

 They vary considerably in the development of the 

 black spots on the fulvous patch, almost obsolete in 

 some through all gradations to the fullest development ; 

 the patch varies in like manner, and also in form ; 

 lastly, they vary in size." 



The caterpillar is yet unknown. 



The butterfly has the wings above of a dark brown 

 colour. Each wing bears near its extremity a bar of 

 deep but dull red, divided into sections where the 

 brown veins cross. In each section is usually a black 

 spot, but sometimes these are absent, and a few red 

 spots take the place of the bar. The hind wings are 

 smoothly rounded in their outline, and not toothed or 

 scalloped as in the last species (Blandind). The males 

 generally appear towards the end of June, but a few 

 sometimes earlier. The females, however, come later,
