Through the courtesy of the officials of the American Museum 

 of Natural Histor\^ we have been allowed to use the magnificent 

 series of Beutenmueller illustrations of certain Cynipid galls, and 

 by arrangement with the executor of the will of the late S. Millett 

 Thompson of Providence, R. I., we were at liberty to reproduce fig- 

 ures from the original photographs used in the Illustrated Catalogue 

 of American Insect Galls by the late Dr Millett Taylor Thompson. 

 The late Cora H. Clarke of Boston, Mass., well known as an 

 enthusiastic student of insect galls, kindly placed at our disposal 

 a number of excellent illustrations, and with the consent of Mr 

 L. H. Weld of Evanston, 111., we have reproduced a nimiber of 

 his admirable photographs. Miss Fannie A. Stebbins, Springfield, 

 Mass., has loaned the use of several illustrations. These and the 

 approximately two hundred original line drawings and a number 

 of illustrations appearing in earlier publications of the office are 

 also incorporated in this work, the whole making an unrivaled series 

 in the literature of American insect galls.
