1165. Caligula castanea : n. sp. 



cJ ? Of the colouration of C. simla but much smaller, the pale band 

 on the fore-wings as pale as in that species but narrower, markings 

 very similar to C.japonica, Butler: Ann. Mag. N. H. (4), xx. p. 479 

 (1877), of which it is no doubt merely a pale form ; but this form seems 

 to be constant, and there is a fine series of it unnamed in the B. M. 



Expanse of wings 4^ to 4^ inches.

Nearly allied to C. simla, but the difference in the markings in 

 the centre of the fore-wings seems to be constant in all the examples 

 I have examined.
