of the Genus Teracolus, Swains. 389 
The wet-season variety has the apex of the primaries and 
the secondaries greenish yellow instead of pinky buff on the 
under surface; intermediate specimens also occur, and it may 
be doubted whether the three forms do not all fly simul- 
taneously, as is frequently the case in very dry regions. 
There are altogether seventeen specimens in the Museum 
series. 
3. Teracolus ocellatus. 
Teracolus ocellatus, Butler, P. Z. S. 1885, p. 767. 
A single wet-season male of this still rare species was 
obtained by Mr. J. G. Thrupp in Somaliland in 1884; I 
have since seen a second example in Miss E. M. Sharpe’s 
collection, I had long expected to see this butterfly betore 
it actually came to hand, as I felt certain that some inter- 
mediate form must exist between the salmon-colourel 7. pro- 
tractus and the half-salmon, half-white 7. phisadia. As 
might be expected, 7’. ocellatus is somewhat nearer to 7’. phi- 
sadia than to the Indian species, both in outline and in the 
general pattern of the primaries. ‘The dry-season form is at 
present unknown, but it is quite possible that, as in 7. phi- 
sadia, it may only represent the female phase of the species.

The male of this species is a wet-season form and the 
female (in all its varieties) invariably dry-season ; of course 
they all fly together at the same time. The species occurs 
abundantly in Arabia and ranges to Syria. According to 
Mr. Marshall it also occurs through Abyssinia to Senegal, 
but I have never seen an African specimen; its reputed 
occurrence in Madagascar is doubtless due to an error in the 
labelling of a collection from Aden containing single examples 
of many species which have been thus included in M. Gran- 
didier’s splendid work by M. Mabille. It would, indeed, be 
remarkable if Adenese species could leap over Somaliland 
and the intermediate sea to Madagascar without appearing 
upon the African continent.
