This moth has about as wide a range as A. janata, but has not been recorded quite so extensively from Polynesia, only as far east as Samoa. Our eight Guam specimens were mostly collected at light: Piti, Sept. 13 , 20, Oct. 12, Nov. 3, Swezey . One was reared from a pupa found among paper rubbish by a student at the Agricultural School, Piti, Oct. 28 . One specimen in U. S. National Museum, Fullaway, 1911 .
