TORTRICES, TINE/E, AND PTEROPHORI. 



THE Tortrices or Twisters are so called because 

 many, though not all of them, are in the habit of 

 twisting or rolling up leaves while in the larval state. 

 There is little difficulty in knowing whether a 

 Moth belongs to this group. In these, the body is 

 comparatively short and slender, and the wings have 

 a peculiar wave on their costal margin, so that when 

 the insect is at rest with closed wings, the outline is 

 curiously like that of a bell. We will take a few of 

 the most conspicuous of these Moths. 



AT their head come some Moths which scarcely 

 seem to belong to the Tortrices. They are popularly 

 called by the name of Silver Lines, because their 

 green wings are crossed with some narrow lines of 

 silvery-whiteness. As a rule, the Tortrices are all 

 little Moths, but some of the Silver-Lines are excep- 

 tions to this rule, and are, indeed, the very giants of 

 their race. 



There are but three of these insects, which form 

 the family of the Cymbidae, a name which will be 

 presently explained. The commonest of them is the
