Ranges from Bombay southwards to Madras and Ceylon. 
The seasonal forms of this species follow the usual rules, 
the wet-season forms being heavily marked above, yellowish 
and white with the usual markings below ; the intermediate 
forms are similar above, but the females show more orange in 
the apical black patch ; the dry-season forms are more lightly 
marked above and much more rosy and more strongly striated 
below. Of each form there are two phases, one showing a 
double bar on the under surface of the male secondaries, the 
other only showing a costal dash or dot. Of the double- 
barred type are, first, the wet-season form, which has received 
no distinctive name ; then the intermediate form, representing 
T. pseudevanthe ; lastly, the dry-season form, which is typical 
of T. eucharis, Of the costal marked type the wet-season 
form is again unnamed; the intermediate form is 7. aurora ; 
and the dry-season form 7’. pallens, which differs from all the 
other phases in showing no trace of the dusky spot on the 
inner edge of the orange apical patch in the male. 
32. Teracolus evanthe. 
Anthocharis evanthe, Boisduval, Sp. Gén. Lép. i. p. 567 (1836); Mabille 
in Grand. Mad. pl. xli. figs. 1, 2 (1887). 
Anthocharis ena, Mabille, Bull. Soc. Philom. (7) iii. p. 134 (1879); 
Grand. Mad. pl. xl. figs. 6, 6 @ (1887). 
Madagascar. 
This species appears to have no wet-season form. The 
variety 7. ena is perhaps a little drier in character than the 
type, but both belong to dry-season phases. 
33. Teracolus evanthides. 
Callosune evanthides, Holland, Proc. U.S. Nat. Mus. vol. xviii. p, 268, 
pl. viii. fig. 9 (1895). 
Aldabra, Comoro Islands. 
Allied to C. evanthe, but evidently distinct. It has the 
brown irroration and striation of the under surface charac- 
teristic of the dry-season 7’. evanthe of Madagascar, but upon 
a pale yellow ground-tint, whereas in 7’. evanthe the ground- 
colouring of the under surface is dead white.
