This pure white moth is known from Ceylon, Burma, Cocos Keeling Island, Christmas Island (Indian Ocean), and New Caledonia. It was not previously recorded in Guam, although there is one specimen in U. S. National Museum, collected by Fullaway in 1911 . It came commonly to our screen at night at Piti . Specimens were taken Aug. 18 , 19 , 20 , Sept. 4 , 7 , 11 , 12 , 13 , Oct. 2 , 10 . We collected it in the open only twice; Sumay Road, in mangrove swamp, May 23, Usinger ; Tumon, swept from Thespesia populnea , May 30, Swezey . We did not find its caterpillar, so learned nothing of its habits.
