tion by its injuries to junipers, the leaves of which it fastens 

 together with silk. In this way it makes a more or less per- 

 fect tube within which it lives. The moth expands about 

 one half inch, and has bright, glossy, orange, fore wings, 

 crossed by four reddish brown bands. 



Family TORTRICIM) (Tor-tric'i-dae). 



The Typical Tortricids {Tor 'tri-cids). 



The Tortricidae agree with the preceding family in lack- 

 ing a fringe of long hairs on the basal part of vein VII of the 

 hind wings, but differ in that vein VII a of the hind wings 

 separates from the main stem before the outer third of the 

 discal cell. More than one hundred and twenty North 

 American species are known. 



Several of our best-known members of this family belong 

 to the genus Caccecia (Ca-cce'ci-a). These may be called the 

 Ugly-nest Tortricids, ugly dwelling being the meaning of 

 Caccecia, and also descriptive of the nests of the larvae of 

 these insects. 



Figure 291 represents the nest of the larva of Caccecia ro- 

 sana (C. ro-sa'na), which we bred on currant ; and Figure 292, 



the adult of this species. This 

 moth expands three fourths of 

 an inch. The fore wings are 

 olive-brown, crossed by bands 

 of darker color ; the hind wings 

 are dusky. This species differs

from the two following in that each larva makes a nest for 

 itself.
