(J. 11 mm. Up per side. — Foreivimj brown, with a white 

 central elliptical area occupying a portion of cell, but not extend- 

 ing to base or inner margin. Iluidwhig wholly brown. Cilia 

 white. 



Underside. — Forewitig white, with a brown apical area, 

 and a decreasing brown outer margin marked by two parallel 

 series of white lines (one marginal) interrupted by the nervules. 

 Cilia brown. Illndwing v/hite with a marginal series of brown 

 spots encircled with white; a large black oval spot present 

 between costal nervure and subcostal nervule at apex. 



^.13 mm. U p p e r s i d e. — ForeA.ving with central white area 

 smaller than in ^. Hindwing with indications of a white marginal 

 line. 



Underside. — i^o?'6i(;m^ with brown outer margin broader, 

 and the two white series of lines dividing up the brown margin 

 into a series of spots; a further series of brown spots some little 

 distance from the brown outer margin. Hindicing as in (J, but 

 with the addition of another series of submarginal brown lines. 



The above descriptions are taken from what I believe to be the 

 only two known Australian specimens, in the Macleay Museum, 

 from Darnley Island; and these were caught a number of years 

 ago. The colour of the upperside in freshly caught specimens 

 will probably be black. 



De Niceville considers that the four described forms belong to 

 one species. They vary from the wet-season form (A', horsfiddi, 

 Dist.), which has no white on the upperside, to the dry- season 

 form (iV, gaura, Moore), which has large white areas on upper- 

 side in both wings. Intermediate between these two forms come 

 typical N, zalmora, Butl., and N. dharma, Moore. 



Almost the s^>me variation as this is shown in the somewhat 

 allied species Megisha mcdaya, Horsf.; but in Australia it is the 

 whitest form of that species that is present, while in N. zaiwora 

 it is one of the darkest forms that we have, though it is quite 

 possible that, w^hen more specimens of these two species are 

 obtained and at different times of the year, it will be found that 

 they exhibit as much variation as they do in India and the Malay
