S • Very close to Ch. latona stephanus, but the postdisco-submarginal patches 

 of the upperside of the hindwing partly separated from each other, the admargiual 

 tawuy intersjiaces at least vestigial between all the veins. 



? . Wings aboce. Forewing : discal luniform bars appearing farther away from 



the ])Ostdisco-submarginal patches, the latter being smaller, than in papuensis and 



stephanus, well separated from the marginal line. Hindwing : discal bar C — SO" 



well marked, all the other discal (luniform) bars vestigial; the ground-colour between 

 these discal Innules and the marginal line of (about) the same pale orange-yellow 

 colour as the disc at the outside of the median bars C — R- ; postdisco-submarginal 

 j)atches farther away from the marginal line than in the allied races from German 

 and Dutch New Guinea, more triangular, and marginal line much thinner. 



Underside more yellow than in the before-mentioned races, the discal (black) 

 lunules of the forewing farther away from the rather well-defined jmstdisco-sub- 

 marginal patches, the interspace between the lunules and the patches pale yellow ; 

 cell uniform in tint. On the hindwing the interspace between the discal lunules 

 and the tawny chestnut, postdiscal, spots broader than in papuensis and stephanus, 

 the pale yellow admarginal interspaces more than twice the width of those of the 

 allied New Guinean subspecies ; marginal line thin, well separated from fringe : 

 median interspace of both wings rather dark brown.

Both Dr. Pagenstecher and Herr Ribbe say that the specimens they have 

 examined are not distinguishable from the individuals from German N. Guinea 

 (Konstantinhafen), while Dr. Butler considers them to be specifically distinct 

 from papuensis, layardi being " a representative of C. cimon" Ch. cimon stands in 

 Dr, Butler's Revision two pages separate from Ch. latona, of which it is a synonym.
