Among the sjjecles which Wiedenumn places in the genus Ortdtis, there are three closely allied ones, which do neither be- long in the genus Ortatin, nor in the group Orlalinn. They have to form a separate genus in the group riah/nluudiKi, which I will call Enoistoneura. They are: Oiialiii miK Fab., parallda Wied., and lugens Fab.; Trmnla alh »'t V i' , I •M 1 *' t. ^liAVi.
