 Australia {Du Boulay). Type, B. M. 



This species comes nearest to the Javan form which I 

 considered, in my Revision, to be the C cyrene of 

 Westwood ; Mr. Moore has, however, shown me that the 

 latter is closely allied to if not a variety of C. clotlio ; the 

 C. rhesus of Boisduval from the Philippines seems to me 

 to be the same as the species from Java, the latter may 

 therefore provisionally bear that name. From C. rhesus 

 of Java, then, my new species may be distinguished by its 

 greatly superior size, deeper coloration, the absence of a 

 dorsal abdominal line or the black dot at the end of the 

 cell of primaries, the redder and more blurred pale border 

 of the secondaries, and the redder and less distinctly marked 

 under-surface. 



The type of this species has recently been presented to 

 the Collection by H. Walduck, Esq., to whom it was 

 given in Queensland by Mr. Du Boulay. It was probably 

 captured in Western Australia.
