Japanese specimens. Eventually, other more reliable morphological 

 characters may be found to separate these two entities; or, it may be 

 shown that our North American insect merely represents an early 

 introduction of C. niponensis, and that the two names should be 

 synonymized. The correct identity of this insect is of great practical 

 importance because quarantine measures are currently being enacted 

 against the accidental entry of C. n. niponensis into this continent. 

 Thus, it is possible that we are needlessly guarding against a pest 

 species that already occurs in the United States. Carposina n. 

 niponensis, however, is a major pest of pome fruits over much of the 

 Orient, particularly Japan, and it seems unusual that its counterpart in 

 North America has not attracted equal attention. To my knowledge, 

 C. n. ottawana has never been reported as an orchard pest and ap- 

 parently has never been reared from rosaceous fruits. It would seem 

 that if ottawana merely represented a relatively recent introduction of 

 C. n. niponensis into this country, then the moth would be an even
