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. 



Queries. — John R. Smith, of South Pownal, Vermont, U. S., wishes 

 to ascertain the best locality for P. Luna 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 Society. — 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.
