more or less washed with sulphur-yellow, whereas 7. eupompe 
and 1’. pseudacaste are uniformly pure white; the veins 
below are sometimes black-tipped, but never black 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 TT. dirus (=ebore- 
otdes) ; T. immaculatus is a variety of the same approach- 
ing 1’. 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, 1. alberta the dry- 
season form, and 1’, subroseus a starved dry-season form or 
the dry form of the dwarfed 7. 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 7’. dulcts, 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 7’. Danae, whilst even in the 
males of the dry-season form it is far more heavy than in 
the allied species. 7’. Danae is the wet phase, 7’. sanguinalis 
is intermediate, and 7’. Taplind dry, the last-mentioned havirg 
the usual rosy under-surface coloration.

fairly well-marked seasonal variation. The true 7. fausta
