to whether the frenum, or spur, of the hind-wing might not be connected with the 
sound, Mr. Swinton informs us that, according to experiments he made, the 
spur has nothing to do with it. Hehas sent us excellent drawings of the structure 
of the body of H. quercana, which we are sorry we cannot reproduce.—Eps. 
FRidophasia Messingiella bred.—At last I have succeeded in detecting the larva 
of this pretty species. I had fancied it must feed on Equisetum, as that plant 
always grew where I took it most freely. The first week in May, whilst hunting 
amongst the Equisetwm, I observed two leaves of Cardamine omara (large bitter- 
cress) pulled:together by a silken thread; at once I thought of the long sought 
Messingiella, and sure enough, there was a small green larva, not at all unlike that 
of a Plutella. I revisited the locality twice, and collected about a dozen of these 
larve, which fed well, and formed open net-work cocoons similar to those of the 
genus Plutella. Two specimens of the imago appeared on the 18th June. 
The larva is green, rather larger than that of Plute la cruciferarum ; the pupa 
is of a yellowish-green.—J. B. Hopextnson, 15, Spring Bank, Preston, June 24th, 
1871. 
Rhodophea marmorella bred.—Early in May I found several larvee feeding on 
the lichen that grows on some stunted sloe-bushes on Whitbarrow, in Westmore- 
land. I could not find the leaves at all eaten; the larva makes a gallery at the end 
of the sloe-twigs, I fancy mainly to change in, as I found the pupa as well. The 
larva seems sometimes to save itself the trouble of spinning silk by using up the 
wool that was sticking to the bushes, where the sheep had passed through. 
The larva is a flat, brown one, with a black head. Mr. Buckler will no doubt 
describe it better than I can. About a dozen specimens of the perfect insect were 
out when I returned home on the 19th June.—Ib. 
Note on Entomological Nomenclature —Mr. Kirby, in the last number of the 
Ent. M. Mag., states that Linnzeus gave names in 1746 which he, “ with scarcely 
an exception,” altered in 1758. If any one willexamine the first ed. of the “Fauna 
Suecica”’ he will find that no specific names are used in that work, the familiar 
twelve-worded diagnosis being alone appended to each insect. Moreover, in the 
preface to his tenth ed. of the “ Systema” (1758), he says expressly that he uses 
trivial names for the first time; and I can only suppose that Mr. Kirby refers to 
the fact that, after the synonyms, the common name is added ; thus No. 772 is dis- 
tinguished “‘vulgo, Morio:” the essence of a specific name, however, is that it is not 
the common name.—G. R. Crorce, University Library, Cambridge, 3rd July, 1871.

Professor Westwood exhibited the minute-book of proceedings of an Entomolo- 
gical Society existing in London in 1780. The members appeared to have con- 
sisted of Messrs. Drury, Honey, Swift, Francillon, Jones, and Bentley. The meet- 
ings were held weekly, but, in consequence of some internal disagreement, the 
society seemed to have collapsed in about a year. 
Mr. S. Stevens exhibited a collection of Coleoptera, recently made by him in 
Treland. The most interesting species was Chlenius holosericeus, of which he had 
captured several specimens at Killaloe, near Lough Derg.
