Apatura Iris in the New Forest. — I am pleased to find by Mr. Goss's note (vol. xiv, 

 p. 256) my opinion as to the scarcity of A. Iris in the Xew Forest confirmed, but 

 I am inclined to think that his theory of the New Forest being too far westward 

 for A. Iris is scarcely borne out by facts. From what I can learn at Lyndhurst, 

 some 25 or 30 years ago A. Iris was plentiful in the New Forest, since which 

 time, from some unexplained cause, it has almost disappeared there. Again, in the 

 course of a conversation with Mr. Reeks, of Thauxton, near Weyhill, he informed me 

 that the insect in question was, at the proper time, to be taken in some quantity in 

 Cjllingbourne and Dole Woods, near Andover. 



They have, to my own knowledge, been taken in the woods near Salisbury, al- 

 though but rarely ; therefore, I think we must look to some other cause than that 

 suggested by Mr. Goss to account for its disappeai-ance in the New Forest. — H.

Colias Edusa at Folkestone. — I saw a specimen of Colias Fdusa on the borders 

 of Lady Wood, at Folkestone, fly swiftly past me, on the 28th ultimo. — H. V. Knaggb,

On the hahits of Biston hirtaria. — The observation recorded below may, or may 

 not, bear upon the notes on habits of this species published by Mr. Silcock in Vol. 

 xiv of this Magazine, p. 43. 



On the morning of Friday, the 3rd inst., I noticed a ? on the trunk of a lime 

 tree in this road, about nine feet from the ground : I think she was not there on the 

 previous morning. She remained in precisely the same position up to this evening, 

 when I dislodged her with my umbrella during a heavy rain, fearing the weather 

 might prevent a more minute examination. This ^ is in perfect condition, and as 

 inert as is usual in the species : but either she had previously laid all her eggs, or teas 

 originally barren; the latter is perhaps the more probable. To my certain knowledge 

 she had remained about 108 hours without shifting her position in the smallest 

 degree. It is unusually late for the insect. — R. McLachlan, Limes Gi-ove, Lewisham :

Penthina postremana bred ; a species new to Britain. — ^On the 7tli October last 

 when searching for the larva of Cidaria reticulata amongst the veild-balsam {Im- 

 patiens noli-me-tangere) , I split open a few stems of that succulent plant and found 

 an active Tortrix larva, whitish-green, with black head. Mentioning this discovery 

 to Mr. H. T. Stainton he was able to inform me, on referring to Kaltenbach's 

 most valuable work, that Penthina fuligana had been bred by Herr Miihlig from 

 larvae which wintered in the dry stems of Impatiens noli-me-tangere. About the 

 middle of April I split open some stems, and found the larvae were quite lively. On 

 the 4th inst., I bred two lovely specimens of postremana. — J. B. Hodgkinson, 15, 

 Spring Bank, Preston : May 8th, 1874. 



[The namefnligana is employed in Kaltenbach's work as being that used in 

 Staudinger and Wocke's Catalogue, whei'e ustulana and carbonana are quoted as 

 doxibtful synonyms.
