It is evident, from Hewitson’s supplementary remarks, 
that he had more than one species under consideration ; 
but his description of the ¢ contains all the salient 
diagnostic characters of this species (except the possession 
of a sex-mark), and if he had used any other name than 
baldus, Fab., it must have been adopted. The name 
philomela, Johanssen, or philomelus, Linné, must be 
dropped altogether, as it is impossible now to determine 
what insect was intended, although the probability seems 
to be that it was the baldus of this paper, which is very 
common in Java, from whence philomela was described. 
De Niceéville’s investigation of the seasonal dimorphism 
of this species proves conclusively that the dry-season 
form has the ocelli on the under side of the hind wing 
very much smaller than in the wet-season form; it is 
also well to note that the distinctness of the dark bands 
on the under side is in direct proportion to the reduction 
in size of the ocelli; and it must be borne in mind that 
Butler’s description of Y. Marshalli applies only to the 
dry-season form. Distant’s description of methora fits 
the ¢ of this insect well, but his figure is not charac- 
teristic. The specimens of Y. Newboldii in the British 
Museum are all Y. Marshalli, wet-season form, the type 
being a ? in which the uppermost of the subapical pair 
of ocelli is accidentally wanting.
