20 THE CANADIAN ENTOMOLOGIST. 
As it is almost impossible to keep butterflies perfect on pins while 
moving from place to place in wild regions, each specimen of Diurnal 
Lepidoptera of my next collection will be placed in a paper envelope, 
and my subscribers will, no doubt, receive the remainder of their 
specimens in good condition. Moths will be pinned, and collected 
chiefly by sugaring, as I believe it is the cheapest and most prolific 
method of procuring good specimens. I am anxious to obtain three 
additional subscribers for the Northern Diurnal Lepidoptera, to be 
collected during the season of 1873.—WILLIAM COUPER, 38 Bonaventure 
Street, Montreal. 
Quertes.—John R. Smith, of South Pownal, Vermont, U. S., wishes 
to ascertain the best locality for P. Zuna and Ceratocampa regalis ; also 
if there is any published price list of American insects. 
Will any of our readers kindly give the desired information ? 
A New Sociery._-We are glad to learn that a new Entomological 
Society has been started in Brooklyn, N. Y. We cordially wish it every. 
success. 
ExcHANGE.—Mr. W. Cole, of London, Eng., is desirous to enter into 
correspondence with Canadian Entomologists with a view of effecting 
exchange of specimens. For further information address W. COLE, care 
of C. Browne, Esq., 5, Old Square, Lincoln’s Inn, London, England.
