Socotra. 
T. niveus represents the wet-season phase and 7’. candidus 
that of the dry-season; the latter is less heavily marked than 
the type, and the orange patch, instead of filling the apex of 
the primaries, is represented by an oblique pale orange sub- 
apical band of five spots, widest in the middle and narrowest 
at its lowest extremity.

Aldabra. 
This is a very distinct and singularly coloured species. 
Without seeing the type, I should judge that its nearest 
relation was probably my T. niveus, from Socotra. It 
appears to be a wet-season form.

Southern Africa as far west as Damaraland, eastwards as 
far as the Zambesi. 
The seasonal forms of this species differ but little on the 
upper surface; the dry-season male, however, has slightly 
less black on the inner margin and on the inner edge of the 
orange apical patch. C. decdamiordes is the dry-season form.

The seasonal variation of this species is considerably more 
marked than in the southern 7. evenina; TT. stpylus, the
