Tlie Box-elder Leaf-roller adult resembles very closely . in shape, size and 

 whitish markings, the above species. It differs, however, from it in that the 

 general color of the forewings is a much lighter brown, almost a fawn color. 

 The hind wings in the former species contrasted strongly in colour with the fore 

 wings but in this species they are practically the same pale brown or fawn color 

 only a little lighter in shade. Moreover, the white markings, as seen in the 

 photograph, usually continue farther in from the front margin forming in the 

 case of two of them irregular oblique transverse bands reaching most of the way 

 across the wing. In many males there is a noticeable dark brown spot, the size 

 of the head of a pin, enclosed or nearly enclosed by white areas and situated in 

 the middle of the front wing at about the outer part of the first third. There 

 are some very light colored specimens in which the white markings are very 

 indistinct. 



Egg masses of A. rosace- 

 ana, laid on glass. The 

 little line to the side is 

 a young larva just 

 emerged from an egg.

Egg masses of A. semiferana on pieces of apple bark. 



Those in the upper row, with one exception, are 



unhatched; the remainder have hatched.

Tbe adult of the Oblique-banded Leaf-roller is, as seen in the photograph, 

 considerably larger than either of the above species though many specimens are 

 smaller than those pictured. It can easily be distinguished from either species- 

 by the absence of white markings and by the front wings being a dull light brown 

 with two wide darker brown transverse bands on tbe outer half running obliquely 

 outwards from the front margin. The outer of these bands is sometimes incom- 

 plete. The hind wings are of a lighter l)rown than the front. There are some 

 very pale specimens of this species, too, (v»m]»an'(l witli the typical forms.
