COMPLETION OF THE LIFE-HISTOEY OF LYCJSNA 



ARION. 



By F. W. Feohawk, M.B.O.U., F.E.S. 



Lycccna arion larva. 



Since July, 1895, I have been endeavouring to complete the 

 life-history of Lycceiia arion, thereby trying to solve the mystery 

 which has hitherto surrounded the last stages of this remark- 

 able larva. Notes and descriptions of its earlier stages will be 

 found in the ' Entomologist,' vol. xxxii. pp. 104-6 (May, 1899) ; 

 voL xxxvi. pp. 57-60 (March, 1903); and in vol. xxxviii. pp. 193-4 

 (August, 1905), is the description of the pupa which Mr. A. L. 

 Eayward and I had the pleasure of discovering in Cornwall last 

 July. This success led to our determination of again visiting 

 the Cornish coast in the endeavour of finding the larva in its 

 last stage, and our hopes of making its acquaintance were realized 

 on the afternoon of June 3rd last. As may be imagined, it was 

 with no small amount of satisfaction that we then, for the first 

 time, had before us a natural object which had never been seen 

 by anyone before, and had been wrapped in mystery and re- 

 mained one of the greatest of entomological puzzles.
