cia. Central fascia broad, distinctly dark brown, sometimes reddish-

 the anal angle. Fringes dark ochreous.

I have now described and figured all the North American species 

 known to me of the genus Tortrix as limited by the late authors of con- 

 tinental Eui'ope. No attempt has been made in this paper toward a 

 systematic arrangement, as some of the species figured are represented 

 by single specimens which would be rendered unfit for the engraver by 

 any examination of the details of their structure. I hope that the de- 

 scriptions with the aid of the plates will render the preservation of such 

 specimens unnecessary.

 this continent. Of the few specimens in collections to which I have 

 had access a large proportion resemble closely varieties of European
