second emergence. I have no doubt, in some places, the 
larva does a degree of injury to the roots of the potato, as 
the moths swarm occasionally in and about potato-fields.— 
J. R. S. Clifford. 
Cerastis erythrocephala at Darenth Wood.—\ took a fine 
specimen of Erythrocephala in Darenth Wood, at sugar, at the 
end of October. I took it at first for a variety of Spadicea; 
I think it might easily be overlooked for a pale variety of that 
species.—J. Moore; 51, Chapel Street, Pentonville.

Preserved Larve of Lepidoptera.a—Mr. R. L. Davis 
exhibited an extensive series of beautifully preserved larve - 
of Lepidoptera and other insects. Among them were speci- 
mens illustrating the complete natural history of Cossus 
ligniperda, and of some other common species. Mr. Bond 
exhibited examples of Zygena exulans, a recent addition to 
the British Fauna, captured at Braemar, by Dr. F. Buchanan 
White. Also a specimen of Catocala Fraxini, captured in the 
Regent’s Park, on the 12th of September last; and he 
remarked that the insect had occurred in that locality for 
three successive years. Furthermore he exhibited a very 
singular variety of Cherocampa Elpenor, from Ipswich, in 
which the central portion of each fore wing was perfectly 
hyaline and free from scales, the insect being in perfect 
condition, and presenting no indication. of the peculiarity 
having been induced by artificial means. 
[These specimens of Zygena exulans have been deter- 
mined as thevariety “ Vanadis,” which fact I mentioned several 
months ago on the wrapper of the ‘ Entomologist.’’ It was 
perfectly excusable for my friend Bond to have overlooked a 
wrapper notice of this kind; but certainly zrexcusable in me 
not to have inserted it in the body of the work.—Edward 
Newman. | 
Black Variety of Melanagria Galathea. Mr. Vaughan 
exhibited a nearly black variety of Arge Galathea, captured 
in Kent by Mr. Farn. 
New British Coleoptera—Mr. EK. W. Janson exhibited 
two new, or recently detected, species of Coleoptera, captured
