THYMELICUS ACT AWN, AND OTHER LEPIDOPTERA 

 OF THE ISLE OF PUEBECK IN AUGUST, 1918. 



I^Y H. Piowland-Brown, M.A., F.E.S. 



The butterflies of the Isle of Purbeck are familiar to most 

 collectors, but a few remarks on some of them may even yet 

 be not out of place. I spent a short holiday at Swanage and 

 Corffe Castle from August 2nd to the 13th, and after a 

 preliminary Vv^et and windy day or two the weather settled 

 down, and all the time I was at Cori'e (August 8th to 13th)
