5. Mimeusemia persimilis, n. sp. 
Very like Eusemia villicoides, the primaries black, crossed by 
~ two or three plumbaginous lines ; a spot near base of cell, a dot 
at centre of costal area, a large spot below it, cut by the 
median nervure and its first fork, and two large spots placed 
obliquely on apical area, yellowish cream-colour; secondaries 
deep orange, with a broad irregular costal and external black- 
brown border, a large black spot across the end of the cell, and
