The next year he writes, "This species is common on Palau, southern Pacifi c[i nJapanese ].", probably based on the two specimens. Unfbrtunatel ythe two female sare not the same species. As shown in the picture hsere ,we cannotjudge which ofthem is the holotype from the original descrjpt iaondn from the label sattached to the specimens. One is nearly perfect, but the other is rather worn and the hindwings are broken. Iwill here choose the former as the holotype ofpalauensts, which is identic awlith lt` s[ytvi aBoisduva l(sy nn.ov.).
