 three smaller dorsal ones. 9 mm. 



This species is transitional to the following group.

 tegular golden ; fore wing with golden fascia? fading out above, the first one meet- 

 ing a dash in the base of the fold, connected by suffusion to the base of the costa ;

 12-14 mm. 



July. 



Ottawa, Ontario, to British Columbia; Europe. 



If the American form is distinct, its name will be chalcochrysa Meyrick.

6. A. freyella Walsingham. Golden yellow and silvery white. Base of the fore 

 wing streaked, the rest marbled, tending to form wavy anastomosing transverse 

 bands; tegula? golden; antenna? annulate. 8 mm. (abdominalis Zeller, in part,

 passing through the stem from leaf to leaf, completely emptying the leaves, and 

 scattering the frass. It hibernates in the mine; it pupates in May, in a cocoon 

 of open meshes, formed outside the mine. 



Connecticut to southern Ohio.
