284 Mr. A. R. Wallace's Notes 



This must be considered as an extreme form of the 

 New Guinea type of B. Tyclea, from which^ however^ it 

 differs in the shape of the anterior wing, as well as in 

 markings. The females of this species and of D. Hewit- 

 soni have a great resemblance to some of the forms of 

 Melanitis Melane, Hewits., which inhabits the same islands. 



12. Diadem A Diomea. 



Diadema Diomea, Hewitson, Proc. Zool. Soc. 1861, p. 51, 

 pi. viii. f . 2 {$). 



Hah. — Menado, Celebes (Wallace) . 



The female differs only in having the bands broader 

 and whiter, and the submarginal spots on the hind-wings 

 more distinct. 



13. Diadema featerna, n. s. 



Male: very near D. Dimnea, rather smaller; upper- 

 wings less elongate, and the outer margin straighter. 



Above; the bands are smaller, and completely covered 

 with a violet blue gloss, costal margin entirely black, 

 band of hind-wings of four spots only. 



Beneath; has a large oval white spot above the origin 

 of the first branch of the subcostal vein, which is entirely 

 absent from both sexes of D. Diomea. 



Hah. — Macassar, Celebes (Wallace) . 



This insect is certainly very close to D. Diomea, but it 

 differs decidedly in the form of the wings, as well as in 

 several characteristic markings. Many species, both of 

 birds and insects, are found exclusively in the North or 

 South of Celebes, but very rarely do they possess repre- 

 sentative species. One such case, however, occurs in 

 birds, and with that now noticed, would seem to indicate 

 that the extreme points of this strangely shaped island, 

 have formed two or more distinct islands, at a not very 

 remote epoch. 



14. Diadema antilope.

 antilope, Godart, Enc. Meth. ix. 397. 



Male: smaller. Above; light olive-brown, with a large
