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 larve constantly, even in mid-winter, used 
to come out of their hiding-place during the night and feed 
upon the leaves, of which there are always a few remaining 
till the spring.—E. K. Robinson; Eagle House, St. Leonards. 
The time of Appearance of Pseudo Bombyces.—In Newman’s 
‘British Moths’ the time of pupation of Ptilodontis palpina, 
Notodonta ziczac, N. dicteea, N. dromedarius, and one of the 
Drepanule—Platypteryx falcula, is given as September or 
October. I have found both last year and this that the greater 
number of larve of these species spin up in the beginning 
of July, reaching their perfect condition a few weeks after; 
and this not only i in breeding-cages, but in a state of nature. 
Noctua brunnea and N. triangulum, which I have bred from 
ggs laid in June, have already become pupe instead of hyber- 
nating.—F’. K. Robinson; Eagle House, St. Leonards. 
Treatment of Larve of Chelonia villica and Pericallia 
syringaria during Hybernation; and of the Pupe of 
Burrowing Larve.—Can any reader of the ‘ Entomologist’ 
inform me the best mode of treatment of larve of C. villica 
and P. syringaria during hybernation? Mine have almost 
invariably died off or been attacked by fungus. Also, how 
to keep those pupe 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 I 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 [ kept them in a friable earth, with moss above, 
and in a wooden box, as when damping.—J/. Stewart ; New 
Cross. 
Acidalia emarginata, §c.—1 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, | 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 larve. Colias Edusa and C. Hyale have both been 
captured here this month.—Joseph Anderson, jun.; Chichester.
