no doubt keep a hold on tlie cast larva skin. ]\Ir. E. Newman 

 noticed the larva skin to be attached to the gi-ass by silken 

 threads. It certainly avoids serious risk from falling by 

 suspending itself veiy nearly down to the roots of the grass. 



This is, witliout doubt, our most abundant and universally 

 distributed butterfly, being probably, of all others, the best 

 adapted for our chmate. This is shown by its comparative 

 indifference to weather. Not only does it flit about with a 

 sort of flapping motion — as though the wings touched, above 

 and below, at every stroke — in every grass field at all 

 hours of the day, when it is sunny and pleasant, but a passing 

 footstep will stir it up to fly in every direction, when the 

 weather is not pleasant at all, but raining hard, and the 

 sudden advent of a thunder shower will sometimes rouse each 

 lazy butterfly, perhaps to look for a dryer jilace. Mr. Dale states 

 that he has seen it betaking itself to trees in such weather. 

 Certainly in warm rainy weather it will at times fly high 

 and round about in an aimless sort of manner, even visiting 

 trees and leaving them again, and probably it, in some cases, 

 settles down in them for the night. It does not seem to 

 frequent the higher mountains, nor to occur in the Orkneys 

 and Shetlands, and in one or two places, as, for instance, at 

 Huddersfield, appears, from some unexplained cause, to have 

 died out ; but with such exceptions, there hardly seems to be 

 a grassy field in the United Kingdom from which it is 

 entirely absent. It is found throughout Europe, excej^t 

 Alpine and Polar regions, in North Africa and the Canaries, 

 Syria, Armenia, and Asia Minor.
