of the Genus Teracolus, Swains. 497 
should no more regard them as synonymous (as Mr. Marshall 
has done) than I should Ganorts brassice and rape. T’. pseud- 
acaste ranges due southwards, whereas 7’. eupompe appears to 
follow the north-eastern coast, crossing over from Somaliland 
to Aden.

Ranges from the White Nile and Abyssinia south-eastwards 
to Somaliland, and thence across the straits to Aden. 
This species in all its phases can easily be distinguished 
from 7’. pseudacaste by the great reduction of all the black 
markings on the under surface of the wings, the subapical 
spots on the primaries and the discal spots crossing the 
secondaries being almost or wholly obliterated, whilst the red 
subapical stripe and the red discal spots on the under surface 
of the secondaries in the female are strongly emphasized. 
The wet-season form is 7’. eupompe=anteupompe ; the inter- 
mediate phase is 7. theopompe, having a dry-season upper 
surface, but a white under surface; whilst J’. dedecora, in 
which the apex of primaries and the secondaries below are 
rosy, 1s the dry-season phase. The two latter undoubtedly 
fly together, and in Aden it is tolerably certain that all the 
phases emerge at the same time as mere variations, which 
only become seasonally fixed in a more variable climate.

Appears to range from Karachi to Bushire; and one male 
in the British Museum series is said to have been obtained 
at Aden, but this I consider very doubtful. 
‘As I do not admit the identity of 7. pseudacaste with 
_ D. eupompe, still less can I agree to this purely Asiatic 
ae being the same. As arule, it may be distinguished 
at a glance by its narrower and internally arched apical 
carmine patch, but occasionally a male with a fairly broad 
patch does occur, though I believe never a female. Another 
point is that 7. dulcis has the base of the primaries below
