This beautiful and very distinct species is most nearly allied 

 to T. Terpander of Hewitson (Proc. Zool. Soc. 1862, p. 90), 

 which I consider to be the insect figured inadvertently in the 

 'Genera of Uiurnal Lepidoptera' (pi. 21. fig. 3) as the Cla- 

 rissa of Boisduval, the latter being a much larger species, with 

 more strongly falcated fore wings. My species only differs from 

 Terpander, on the underside, in the narrower and darker yellow 

 discal band and smaller white spots of the hind wings.
