Cambridge Entomological Society. 
The November meeting of this Society 
was held on Friday, the 27th ult., at the 
Secretary’s rooms. 
F. Barlow, Esq., Vice-President, in 
the chair. 
F. Stainforth, Esq., Mr. L. Cumming, 
H. Baiubridge, Esq., and F. H. Knapp, 
Esq., were balloted for and elected as 
members of this Society. 
Mr. Preston (of Emmanuel College) 
then read a paper on the structural 
changes observable in the several stages 
of Lepidopterous insects. He described 
the various organs of the larvae, briefly 
reviewing the nervous, digestive, circula- 
tory, respiratory and muscular systems, 
and proceeded to show what modifica- 
tions the insect underwent in its suc- 
ceeding stages as pupa and imago. He 
illustrated his subject by reference to 
numerous diagrams and specimens. 
Several questions arising out of the 
subject of the paper, especially on the 
sensation of insects, were started by 
Mr. Dunning, Mr. Bree and Mr. Crewe, 
and discussed at some length. 
Mr. Brown exhibited H. Peltigera, 
taken near Newmarket, and very pale 
varieties of N. lypica and P. marginaria. 
Mr. Barlow exhibited a splendid black 
var. of Galleria cereana and also a fine 
series of the insect, which he distributed. 
Mr. Crewe exhibited a box of Eupi- 
thecice. 
Mr. Preston exhibited Cynips aplera. 
— A. F. Sealy, Hon. Sec., 70, Trump- 
ington Street.

NAMES. 
to the editor of the ‘intelli- 
gencer.’ 
Sir, — With regard to the letter of 
Mr. T. J. Stainton, in this week’s ‘In- 
telligencer,’ I have to say that I have for 
long past paid much attention to the 
derivations of words, and that I should 
be very happy to work out such a list as 
he speaks of, and which, I believe, from 
my own correspondence with entomolo- 
gists, to be much called for. I have no 
doubt there are others equally willing 
and more capable than myself; but here 
is the hitch I, and probably they, too, 
are unable to venture the risk of losing 
even a few pounds, and the sale of such 
a list as we are speaking of could not 
be expected to be remunerative; and, as
