BOOKS ON ENTOMOLOGY 



An important new Catalogue, No. 4, to be issued early in 

 October, will, like Catalogue No. 3, be devoted entirely to items 

 on Insects. These two Catalogues index in a comprehensive 

 and intelligible manner the largest stock of books on this sub- 

 ject for sale in America. 



Among the many recent purchases to be included in this 

 new Catalogue are the superb library of Mr. George W. J. 

 Angell, chiefly devoted to Coleoptera ; the library of the late 

 George Marx, relating entirely to Arachnida ; also the remain- 

 der of the library of the late C. V. Riley. 



Economic items of especial interest at this time in connec- 

 tion with food problems, will be presented in unusual detail. 



Excerpts from various entomological and other journals, 

 both American and foreign, are available for specialists who do 

 not need full sets or volumes. 



If you wish this new Catalogue, or if you 

 did not receive Catalogue No. 3, apply to
