Kanges 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 T. aurora ; 

 and the dry-season form T. pollens, 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. Gen. Le"p. i. p. 567 (1836) ; Mabille 



in Grand. Mad. pi. xli. figs. 1, 2 (1887). 

 Anthocharis ena, Mabille, Bull. Soc. Philom. (7) iii. p. 134 (1879) ; 



Grand. Mad. pi. xl. figs. 6, 6 a (1887). 



Madagascar. 



This species appears to have no wet-season form. The 

 variety T. 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, 

 pi. 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 T. evanthe of Madagascar, but upon 

 a pale yellow ground-tint, whereas in T. evanthe the ground- 

 colouring of the under surface is dead white.
