Museum is a series, identical wtih the types, bred from leaves of 

 Cottonwood received from Wyoming; also a large series bred from 

 Cottonwood in Colorado by Dr. Dyar. The larva rolls the leaves in 

 the same fashion as does the European populclla. Zeller's types are 

 from Texas." 



In the New Jersey List, 1910, W. D. Kearfott reports the insect 

 from Essex County, larvae in " curled leaves of poplar, not rare." 



None of these authors report the curled leaves lying on the ground 

 under the tree, as at Cold Spring, which may have been an unusual 

 occurrence and due to the effect of some particularly vigorous summer 

 breeze. — Wm. T. Davis. 



BOOK NOTICE. 



A Year of Costa Rican Natural History. By Amelia Smith Cal- 

 vert and Philip Powell Calvert. Octavo, pp. 577, with numer- 

 ous half tone illustrations and map. The Macmillan Co., New 

 York, 1 91 7. Price $3.00. 



This is a book of details and is carefully written. There is rarely 

 an animal or a plant mentioned that is not accompanied by at least 

 a short description of its more striking features. The accounts of 

 plants are particularly numerous, and many of the illustrations are of 

 interesting trees and flowers. A systematic list of plants and animals 

 mentioned, occupies twelve pages near the end of the volume, and 

 the list of Odonata is no doubt most complete, as that order received 

 considerable attention among insects. There is a list of literature 

 relating to the natural history of Costa Rica; also a list of the papers 

 based in whole or in part on the collections made by the authors 

 during their journey. The features of the country are described 

 with much care, and the different localities compared. This is also 

 very useful, for there have been but few naturalists or observers who 

 have given sufficient details to satisfy future generations. Every 

 country changes gradually, the forests often disappear, even some of 

 the insects become extinct, and we can well imagine the lasting 

 interest that will be taken in the natural history of Costa Rica as it 

 was in the davs of the Calverts. — W. T. D.
