tinged with pale yellow, and dusted with brown. On the 

 middle of the inner margin is a large, oval patch of dark 

 brown, forming, 

 when the wings are 

 closed, a conspicu- 

 ous, nearly round 

 spot ; there is a wide 

 streak of the same 

 hue opposite, ex- 

 tending to the front 

 margin, and a dark- 

 brown spot near the 

 tip. In the figure 

 the moth is shown 

 highly magnified. Sometimes this insect appears in immense 

 numbers, and then becomes injurious. 



Remedies. As the cocoons of the second brood remain 

 attached to the trees all winter, abundant opportunity is 

 afforded to destroy them. Any oily or alkaline liquid brushed 

 over them will usually penetrate and destroy the enclosed 

 insect. A minute parasitic fly is destructive to this pest, 

 and the cocoons may often be found perforated with small 

 round holes at one end, through which these tiny friends have 

 escaped. 



No. 54. The Apple Lyonetia, 



Lyonetia saccatella Packard. 



This is a tiny moth, but a very beautiful one, which ap- 

 pears early in the summer; its wings, when expanded, meas- 

 ure only one-fifth of an inch across. It is 

 shown, much magnified, in Fig. 117. The 

 fore wings are of a light slate-gray on the 

 inner half, while the outer half is bright 

 orange, enclosing two white bands, one 

 arising on the front edge, the other on the 

 inner margin, both nearly meeting in the middle of the 

 wing ; these white bands are margined externally with black.
