MICROLEPIDOPTERA OF JUAN FERNANDEZ ISLANDS — CLARKE 45 



ventral lip of ostium of chiloma, absent in imitator, distinguishes the 

 two at once. 



With the type series, but not as part of it, I associate a female 

 from Masafuera, Quebrada de la Calavera (Jan. 15, 1952). This 

 specimen measures 14 mm. in alar expanse and shows slight differences 

 in the size and shape of the ventral lip of ostium, which is narrower 

 and proportionately longer than in typical imitator; but the markings 

 are the same and more material, including males, is needed to prove 

 or disprove the correctness of the association.
