071 Eastern Butterflies. 283 



This beautiful species is strikingly distinct. Mr. 

 Hewitson seems to have been led to class it as a variety 

 of Pandarus from the analogy of D. Lasinassa, which is 

 known to vary enormously; but there are these important 

 differences between the two cases, that many of the most 

 striking modifications of D. Lasinassa occur together on 

 the same spot, that they are connected by innumerable 

 intermediate forms, and that almost all these variations 

 occur in the female, while the male hardly varies at all. 

 D. Pandarus, on the contrary, is strikingly constant in 

 Amboyna and Ceram, where alone it is found, each of 

 the allied forms seems to be equally constant in its own 

 locality, there are no intermediate connecting links, 

 and the males vary quite as much as the females. I have, 

 therefore, no hesitation in naming this as a very distinct 

 species. 



9. DiADEMA OCTOCULA.

Hah. — New Guinea, Waigiou, Batchian (Wallace), Gi- 

 lolo (Lorquin) . 



My specimen from New Guinea has the small blue spot 

 on the hind-wings expanded into an oval white patch, 

 almost as in D. Deois, and the orange-rufous band broad- 

 er; the female has the white bands more distinct, and 

 the ocellate spots on the hind-wings smaller. The speci- 

 mens from Waigiou are intermediate, and as there are 

 other islands between Waigiou and Gilolo, I am inclined 

 to think that a complete gradation of forms will be found.
