more heavily marked variety of the same species, their identity being 

 well shown in the British Museum series, which represents a 

 gradual and unbroken gradation from one to the other. There are 

 three specimens in the British Museum labelled T. cyprcea ; two of 

 them are, in my opinion, 2\ calais and the third a white female of 

 T. amata. Capt. Watson, following Mr. Butler's identification of 

 the insect, considers T. cyprcea to be a synonym of T. calais. 

 Tabricius's descriptions are delightfully vague, but 1 prefer to 

 follow Boisduval in believing -that in t. cypraa he was describing 

 the female of his T. amata.

This handsome species is purely Asiatic, being recorded from 

 Kutch, Punjab, and Baluchistan. As Capt. AVatson has pointed 

 our, the seasonal forms are well marked on the underside, but, 

 curiously enough, they have never been separated like so many 

 others. 



12. Teracolus ocellatus. 



Teracohis ocellatus, Butler, Proc. Zool. Soc. p. 767 (1885). 



This species is of interest owing to the exactly intermediate 

 position it occupies between T.protracius and T. phimdia. I have 

 seen only two specimens— one is in Miss E. M. Sharpe's collection, 

 and the type in the British Museum ; they are both from Somaliland.

In this species the male is quite stable, as is the case throughout 

 this group, but the female is very variable, presenting four 

 gradations : (1) like the male ; (2) yellow, with base of primaries 

 suffused with pink : (3) pure yellow"; (4) white. The latter might 

 easily be mistaken for the Indian T. puellaris, Butler, but may be 

 distinguished by the curved macular discal stripe on underside of 

 secondaries. This is the Western representative of T. protractus, 

 occ;urring in Arabia, through Abyssinia to Senegal, but apparently 

 not south of 10° N. lat. M. Mabille records it from Madagascar 

 and India also; but this must be received with caution, for his 

 idea of the species seems to be a little vague, as he refers to it as " a 

 pretty species intermediate between T. calais and T. dynamene" !
