appear to be identical with a pale variety, also sent to me by 

 Dr. Staudinger. There is, however, no doubt that the 

 majority of specimens in our cabinets under the name of 

 osseata are really interjectaria. Haworth's description of the 

 former species applies to the latter. — Henry Douhleday ;

Argyrolepia Musseliliana. — I have no recollection of the 

 Tortrix which the Rev. H. Burney says I named Argyrolepia 

 Mussehliana. The late Richard Weaver took a few speci- 

 mens of a Tortrix which were certainly identical with those 

 which were given to me by the late M. Becker under this 

 name : they were totally different from the griseana, Haw.= 

 udana, G//., and Dr. Staudinger puts more than fifty species 

 between them in his Catalogue. — Id. 



Larva of Notodonta trilophus. — The larva of this insect, 

 as near as I can give it, is dark green, with a reddish streak 

 along the back and one along the sides, with three promi- 

 nences on the 5th, 6th and 7th segments, and a smaller one 

 on the 12th segment. As to breeding from it, I think where 

 there is one insect there is sure to be some more; though we 

 cannot find them, they are sure to find one another. —

[There is a very exact figure of the larva of N. trilophus, 

 as well as those of N. cucullina andN. bicolor, in my ' British 

 Moths,' No. 13. I thought they might be useful to entomo- 

 logists. — E. Newman.'] 



Does Frost kill Larvce ? — In a paper addressed to the 

 Academy of Sciences by M. Reiset it is distinctly stated that 

 the general belief held by agriculturists, viz., that severe 

 frost kills noxious insects and larvse that grub in the earth, is 

 a fallacy. This proposition led to discussion amongst the 

 members of the learned body. M. Emile Blanchard, after 

 doing justice to M. Reiset's important researches, said that 

 it would be wrong to suppose that naturalists had hitherto 

 lived in ignorance of the habits of larvaj feeding on roots, 

 and that it was a well-known fact that, while the temperature 

 continued mild, they remained near the surface, and on the 

 contrary descended to greater depths as the cold became 

 more intense, so as always to escape the effects of frost. The 

 idea, therefore, that a severe winter would rid agriculture of 

 its greatest enemies was utterly without foundation. M.
