SYSTEMA NATUR.E. 



[The spring is, we believe, the natural time for the appearance of A. 

 atropos on the wing. Mr. Stainton gives August to October for the imago, 

 and from July to October for the larvae! — Vide "Manual." If the pupa? 

 are kept in a warm atmosphere the imago will sometimes appear in the 

 autumn, but it is clear this is not normal. The plants upon which the larva 

 feeds, and upon which the eggs are deposited, are annuals, such as the 

 potatoe and other solenaceous plants. — Ed.] 



Deilephila Galii. — On the 20th. of August I captured a beautiful specimen 

 of this insect hovering over a bed of verbenas, in a garden near the resi- 

 dence of the late Colonel Montagu, who was the first to discover it here. 

 These are, I believe, the only two captures in this neighbourhood. — Idem. 



Clouded Yellow. — On the 4th. of June I saw a fine male Clouded Yellow 

 Butterfly. I did not succeed in capturing it, although I knocked it down 

 with my hat; before I could secure it it arose and flew across a river where 

 I could not follow. I see Mr. Wesley, of Winchester, has noted one on the 

 8th. of June, which is the earliest I have ever known except this one. 

 The Clouded Yellow has been tolerably plentiful here this season. — Stephen 

 Clogg, Looe, September 7th., 1858. 



P. avion in duplicate. — I have a few unset specimens of Polyommatus 

 avion which I should like to exchange with any entomologist for others. — E. 

 R. Elliot, Tresilian, Kingsbridge, Devon.
