Genus ANCYLIS Hubner 

 (i) Ancylis comptana Frolich. (The Strawberry Leaf- 

 roller.) 



Syn. conflexana Walker ; fragarue Walsh & Riley. 



This little insect has proved a very destructive foe of the 

 strawberry in parts of the Mississippi Valley. There are two 

 broods annually. The insects roll up the leaves, and feeding 

 upon the tender paren- 

 chyma, cause the plants 

 to wither and dry. So 

 bad have the ravages of 

 the larvie proved in some 

 places that horticultur- 

 ists have been led to 

 abandon growing straw- 

 berries in those localities. 

 The insect is found in

 size ; b, enlarged view of anterior portion of 

 larva ; c, moth ; d, anal segment of larva. (After 

 Riley.) 



Canada and in the portions of the United States immediately 

 south of the Great Lakes. Although the moth occurs in western 

 Pennsylvania, no great loss from its attacks has as yet been re- 

 ported from this part of the country. 



Genus ECDYTOLOPHA Zeller 



(1) Ecdytolopha insiticiana Zeller, Plate XLVIII, Fig. 29, ? . 



The larva of this species has the habit of boring under the 

 bark and causing gall-like excrescences to appear upon the twigs 

 of the common locust {Robinia). 



Genus CYDIA Hubner 



(i) Cydia pomonella Linnaeus. (The Coddling-moth.) 

 This well-known and most destructive little insect is estimated 

 to inflict an annual loss upon the fruit-growers of America which 

 amounts in the aggregate to tens of millions of dollars. Every 

 one is familiar with the pinkish v/orm which is encountered at 

 the heart of apples and pears. But for every apple and pear
