 three lines. The fore-Avings are of a yellowish-brown color 

 with a purplish reflection, and near the middle of the hind

 The hind wings are of the same brownish color, with their 

 inner two thirds semi-transparent and dull golden-yellow. 



Remedies. — No. 20 ; spray fruit and foliage with No. 5 or 7, 

 to prevent moth from depositing its eggs.
