Ilerr Semper, in his work on the Butterflies of the Philippine Isles, 

 does not apply the name hippoclus to the species of this genus occur- 

 ring in the regions of which he treats, but uses instead the second 

 oldest name, lucina, also of Cramer. His reason for this appears to 

 be that Cramer figured 8. hippoclus with an outer discal series of 

 white instead of violet spots on the underside of the hindwing. No 

 author from Godart to the present day has, however, ventured to 

 keep hippoclus and lucina distinct on account of what is probably 

 a slight inaccuracy of colouring only, nor has Herr Semper been 

 able, as far as I am aware, to produce a specimen agreeing with 

 Cramer's figure of hippoclus. Till this is done, I think it desirable 

 that this species should be known by the older and long-accepted 

 name. Dr. 0. Staudinger, in his "Ex. Schmett.," says that only 

 one species occurs in Amboyna, which must, therefore, be the true 

 S. hippoclus. As regards Herr Semper's new species, 8. anna, 

 he has sent me male specimens of it from the Philippines which 

 do not differ at all, as far as I can see, from male specimens of 

 S. Ivcina he has also sent me from the same region. To judge from 

 his figures of S. anna, the female appears to have the markings of 

 the upperside white tinged with yellow. It is probable, therefore, 

 that S. hippoclus is dimorphic in the Philippines in the female sex, 

 and that the albino form equals S. anna. 



M. Godart describes the female of S. hippoclus as differing from the 

 male in that the bands of the upperside of the wings are white 

 instead of yellow ; on the underside they are paler, and the 

 abdomen is whitish ringed with brown. One of the localities he 

 gives for this species is Java. 



In the "Genera of Diurnal Lepidoptera," vol. i, p. 191, it is 

 stated that the female of " Laogona hyjipocla has the fulvous colour 

 of the upper surface replaced by white." 



Mr. A. R. "Wallace says that the Indian form of S. hippoclus, 

 with a white female, is probably distinct from the form which 

 occurs in Java, Celebes, and the Moluccas, and has not yet been 

 named ; that the type of S. hippoclus is given by Cramer as from
