FAUNA BURUANALEPIDOPTERA, Fam. TORTRICIDAE(5th Communication on Indo-Malayan and Papuan Microlepidoptera)byA. DIAKONOFF(Pflsoeroean, JaYIt).During the expedition to the island of Boeroe t Buru I, Moluccas, in 1921-1922, some Microlepidoptera were collected by Dr L. J. Toxorzos which noware preserved in the Leiden Museum. Although they include only a few Tortri-cidae, there are interesting forms among these. The following list. contains 6genera and 9 species; 3 species are described as new.CACOECIADES.Adoxophyes privatana WALK.Station 9, 3.VI; 17.VI; 4.VII. ] C, 2 '?Adoxophyes moderatana IVALK.Station 9, Station A, 11.'V; 12.VI; ] 8XI. 1 .j, 2 S'.Adoxophyes rufostriatana P.'.c.Station 1, Station 7, IV; VI; IX. 4 '?, 2 specimens ex larva.Epagoge affinianaWALK.Station 9, 19 - 20.V. 2 d.Homonacoffearia NIE'1'N.Station 1, V.
