die in the winter. This year I have succeeded ; and I 

 believe the reason is that a bramble plant was growing in 

 their box, and the larva3 constantly, even in mid-winter, used 

 to come out of their hiding-place during the night and feed 

 npon the leaves, of which there are always a few remaining 

 till the spring. — E. K. Robinson; Eagle House, St. Leonards. 



The time of Appearance ofPseudo Bomhyces. — In Newman's 

 'British Moths' the time of pupation of Plilodontis palpina, 

 Notodonta ziczac, N. dictaea, N. dromedarius, and one of the 

 Drepanula? — Platypteryx falcula, is given as September or 

 October. I have found both. last year and this that the greater 

 number of larvae of these species spin up in the beginning 

 of Jul}', reaching their perfect condition a iew weeks after; 

 and this not only in breeding-cages, but in a state of nature. 

 Noctua brunnea and N. iriangulum, which T have bred from 

 eggs laid in June, have already become pupae instead of hyber- 

 nating. — F. K. Robinson ; Eagle House, St. Leonards. 



Treainieni of Larvce of Chelonia villica and Pericallia 

 syringaria during Hybernation ; and of the Pupce of 

 Burroiving Larvce. — Can any reader of the ' Entomologist' 

 inform me the best mode of treatment of larvae of C. villica 

 and P. syringaria during hybernation ? Mine have almost 

 invariably died off' or been attacked by fungus. Also, how 

 to keep those pupae which burrow underground .'' I have 

 tried both damp and dry earth, and by the former mode lost 

 many through rot or fungus; and by the latter they have 

 become so dry as not to be able to escape from the pupal 

 envelope. When damping them 1 kept them in a wooden 

 cage, with a depth of earth about four inches, and a layer of 

 moss above, and damped them about once a fortnight; by the 

 latter mode I kept them in a friable earth, with moss above, 

 and in a wooden box, as when damping. — F. Stewart ; Neiv 

 Cross. 



Acidalia emarginata, S^c. — I took a nice series of this 

 somewhat local species during the last week of July, and 

 until the 8th of August : judging from their brightness and the 

 perfect condition of the cilia, 1 should say the insects had but 

 very recently emerged. Is not this unusually late for them ? 

 I should be obliged for information as to the food-plant of 

 the larvae. Colias Edusa and C. Hyale have both been 

 captured here this month. — Joseph Anderson, Jan.; Chichester.
