Death's-head Hawk-moth at Skerry vore Lighthouse. — 



To Mr R. Wilson, lighthouse-keeper, Skerryvore, I am indebted for 

 a Death's-head Hawk-moth {Acherofitia atropos) which he found 

 clinging to the wall beside the entrance door to the lighthouse 

 tower, on the forenoon of i8th September last (191 5). A strong 

 breeze from the south-east was blowing at the time, and for a 

 fortnight before the wind had been continuously in that direction. 

 The specimen is a male, with an expanse of 4^ inches. The 

 occurrence of the Death's-head at this distant Hebridean rock- 

 station is another demonstration of the insect's great power of 

 wing. We are left wondering whence it came, and whether it was 

 one of a migratory flight. Unfortunately, moths cannot very well 

 be "ringed" like birds. — Williaini Evans, Edinburgh.
