IG mm. U p p e r s i d e. — Foreioing with costal margin brown, 

 apex broadly brown, outer margin brown decreasing in width to 

 angle, basal fourth brown, rest of wing pure white; this white 

 area almost circular, occupying -^ cell, extending above it and 

 also reaching inner margin Ilindwing brown, with a white 

 almost circular apical area, which beginning at about the middle 

 of costa extends downwards just into the end of cell and then 

 round towards apex. 



U n d e r s i d e. — Foreiving white, with much more restricted 

 l)rown margins. Costa only narrowly brown, apex and outer 

 margin less broad than on upperside ; brown outer margin 

 marked with a faint series of dots between the nervules, 

 inside of which is another series of larger white dots. A black 

 spot in middle of cell towards costa, a second above the cell and 

 below subcostal nervule, and three irregularly between nervules 

 at about J length of costa; these three extend at intervals along- 

 inner edge of outer marginal band. Hhidwing white, with a 

 brown narrow outer margin extending from near middle of inner 

 margin nearly to apex; a fine marginal white line interrupted by 

 the nervules, above which is another series of white dashes on 

 the brown outer margin as on outer margin of forewing; towards 

 anal area and above brown outer marginal band, three brown 

 dashes running parallel to outer margin. The most striking 

 feature of the underside is a very large black spot situated between 

 costal and subcostal nervures, just above the end of cell. (In 

 the allied smaller species X. zalmora, Butl., this black spot is 

 situated at the apex). 



The specimen {^ ?) from which this description is taken is in 

 the Macleay Museum from Daridey Island and is the only Aus- 

 tralian specimen I know of. Having been caught many vears ago, 

 the colour has probably faded, and freshly caught specimens 

 would in all likelihood be black and white.
