The Scottish Naturalist. 41 



Time of Appearance— Imago. June, July; August-October. Larva. 

 July-October. Food-plant. Potato, &c. 



This species affords a good instance of the effect that cultivation has in alter- 

 ing the fauna of a country. The native food-plants (unless perchance the 

 insect had once some other and now forsaken food-plant), arc so few, and so 

 comparatively rare, that it is probably entirely owing to the introduction and 

 cultiration of the potato that Acherontia atropos now inhabits Scotland and 

 some other countries.
