Primaries grey, semitransparent, the borders narrowly 

 ochreous, and a large oblong spot of the same colour just be- 

 yond the cell; basal area tinged with ochreous ; two irregular 

 blackish stripes, as in most species of Botys, the outer one 

 abruptly mangled from below the first median branch ; a 

 blackish spot near the end of the cell, and a submarginal 

 series bounding the external border, the inner edge of which 

 is irregularly zigzag ; secondaries ochreous, with a small spot 

 at the end of the cell, two irregular series towards outer 

 margin, and a large subanal spot dusky : body ochreous. 

 Under surface nearly as above, but the stripes across the pri- 

 maries obsolete. Expanse of wings 27 millim. 



Banks of the Wai Levu, Viti Levu. 



One imperfect example, but so distinct from any species 

 hitherto described, that I do not hesitate to characterize it.
