THE STUDY OF INSECTS. 



phod'e-rus pol-i-ta'na). One of the most interesting of Tor- 

 tricid nests occurs commonly on white pine. Each nest 

 consists of from six to ten leaves drawn together so as to 

 form a tube, and is lined within with silk. This tube serves 

 as a protection to the larva, from which it comes out to feed 

 upon the ends of the very leaves of which the tube is com- 

 posed ; in this way the tube is shortened. We bred the 

 moth from nests collected at Ithaca, New York; but we 

 have found similar nests as far south as Florida. The moth 

 expands one half inch. Its head, thorax, and fore wings are 

 of a dull rust-red color, with two oblique paler bands cross- 

 ing the fore wings, one a little before the middle, the other 

 beyond, parallel to it. 



Superfamily TINEINA (Tin-e-i'na). 

 Tlic Ti acids (Tin 1 c-ids]. 



The Tineids are nearly all minute moths with narrow 

 wings, which are bordered with wide fringes. A few species 

 are of considerable size, and have broader wings, with nar- 

 rower fringes. 



The narrow-winged forms can be distinguished from all 

 other moths by the shape of the wings and the great width 

 of the fringes. The moths figured below (Figs. 298, 299, 

 300, 302) illustrate this. It should be remembered that in 



each of these figures the insect 

 is represented greatly enlarged ; 

 in most cases the size of the 

 insect is represented by a hair- 

 line near the figure. 



The wide- winged forms are 

 most surely distinguished by 

 the venation of the wings. In 

 its more general features the 

 venation of the wino;s in this
