The reduction of Platypodidae and Scolytidae to subfamilies of Curculionidae by certain recent authors is questioned. Several fundamentally important anatomical characters that could not possibly have been derived from Curculionidae are cited. Platypodidae (including Coptonotidae) is recognized provisionally as a derivative of Scolytidae; Scolytidae, with subfamilies Hylesininae and Scolytinae (including Ipinae), is also recognized as a family. Protoplatypus, new genus, for P. vetulus, n. sp., a primitive platypodid from New Guinea, and Protohylastes, new genus, for Pr. annosus, n. sp., a primitive scolytid from Queensland, are described.
