200 THE CANADIAN ENTOMOLOGIST. 



Purchase of Insects. — It often happens that an Entomologist is at 

 a loss to procure specimens of certain rare species that he desires for 

 purposes of study or to complete a series in his cabinet ; he has seen 

 them, perhaps, in the collection of a friend, or read of them in some 

 publication, but is unable to obtain them for himself. We are glad to 

 find that a provision has been made for such cases by the establishment 

 of the " Philadelphia Agency" for the sale of specimens of insects ; it 

 is mider the management of Mr. J. H. Ridings (518 South 13th Street,) 

 and is evidently in close connection with the American Entomological 

 Society. The Agency not only sells to purchasers, issuing price-liats of 

 species from time to time, but also receives and disposes of collections 

 from individuals upon commission. The names, moreover, of all insects 

 sold by the Agency are guaranteed to be correct. We would recommend 

 any of our friends who desire to procure rare and beautiful specimens, to 

 send to the Agency for a price-list.
