more or less washed with sulphur-yellow, whereas T. eupompe 

 and T. pseudacaste are uniformly pure white ; the veins 

 below are sometimes black-tipped, but never blaek throughout, 

 and, as already hinted, the apical patch is carmine, with a 

 faint lilac shot rather than crimson. The females vary much 

 in the colouring of the apex in all three species. 



The wet-season form is represented by T. dims { = ehore- 

 oides) ; T. immacuJatus is a variety of the same approach- 

 ing T. eupompe in the partial obliteration of the spots on the 

 under surface, although differing in the colouring of the 

 apical patch and sulphur tinting at base of primaries below ; 

 T. dulcis is a starved wet-season form, T. alherta the dry- 

 season form, and T. suhroseus a starved dry-season form or 

 the dry form of the dwarfed T. dulcis.

Ranges throughout Wallace's Ceylonese subregion — that is 

 to say, from Bombay to Madras and Ceylon. 



This species is in some respects nearer to the African 

 T. pseudacaste than to T. dulcis, there being no sulphur- 

 yellow at the base of the primaries on the under surface of 

 the males and the carmine apical patch being distinctly 

 broader than in the latter species in both sexes; the heavy 

 continuous black bordering to the secondaries in the wet- 

 season form is characteristic of T. Danae, whilst even in the 

 males of the dry-season form it is far more heavy than in 

 the allied species. T. Danae is the wet phase, T. sanguinalis 

 is intermediate, and T. Taplini^xjj the last-mentioned havirg 

 the usual rosy under-surface coloration.

The range of T. fausta appears to be from Syria and the 

 Turko-Persian frontier, through Afghanistan, into North- 

 western India, where it becomes slightly modified and exhibits 

 fairly well-marked seasonal variation. The true T. fausta
