Piti , June 16, at light, Usinger ; Asan, Nov. 2, a chrysalis found in webbed leaf on Erythrina indica , moth issued Nov. 9, Swezey. A few small caterpillars on an Erythrina tree at Agat , Oct. 17, may have been this species but we were not successful in rearing them . The tree was nearly defoliated, as though the caterpillars had been very abundant previously. There is one specimen in U. S. National Museum and one in Bishop Museum , Fullaway , 1911 .

This fine large moth has a wide distribution from Africa throughout the Oriental region to New Guinea and Australia, and to Fiji and Samoa. We record it for the first time in Guam.
