NORTH AMERICAN EUCOSMINAE. 31 



the more important references are given above. The purely European 

 synonymy is also omitted. It is of chief economic concern as an 

 apple pest. 



Male genitalia figured from specimen in National Collection, 

 reared from apple (New York). 



Distribution according to specimens in National Collection, Amer- 

 ican Museum, and collection Barnes : New York, Massachusetts, Con- 

 necticut, New Hampshire, New Jersey, Pennsylvania, Ohio, Wash- 

 ington, British Columbia. 



The variety lariciana Heinemann is only a color form without the 

 characteristic white median shading on fore wing. It does not ap- 

 pear to be in any sense a local race and shows no variation in geni- 

 talia from the typical ocellana. I have seen specimens from New 

 York, New Hampshire, and British Columbia. Heinemann described 

 it as a larch feeder. Our reared specimen, however, was from apple..
