My impression is, though I can scarcely pi-ove it by lists of species, 

 that the insects of this mountain region, are almost purely Indo- 

 Malayan, or at least more so than those of the coasts. If this is true, 

 it does not at all agree with Mr. "Wallace's belief that the Indo-Malayan 

 element is of recent introduction. As these mountains are very easy 

 of access from Bima, where steamers stop every month, and as travelling- 

 in the island of Sarabawa is safe and pleasant, it seems a pity that 

 some competent ornithologist does not investigate the birds of this dis- 

 trict, which ought to afford many novelties. 



Family Danaid^. 



1. Salpii^x mbizon, n. sp. 



Male, above, forewing rich brown with blue reflections, a short 

 slender pale lilac spot in the interno-median space, a costal spot and 

 seven large inner- submarginal ones, light blue with purple reflections, 

 generally pointed outwardly and inwardly, the second largest, separated 

 only by a vein from the first, which is prolonged costally, the last with an 

 obscure streak below it. Hindwing with the blue gloss much less conspi- 

 cuous, the velvety patch pale ochreous extei-nally, darker internally ; two 

 or three small subapical lilac spots. Below dark brown, both wings with 

 the cell and the spaces just beyond it much paler than the outer part. 

 Forewing with a costal lilac dot, and sometimes one or two subapical, a 

 larger one in the lower median space ; below the lower median vein a 

 large ochreous area, pale brown in the middle, extending below the 

 subraedian vein, enclosing a short sericeous band. Hindwing with a 

 varying number of minute inner-submarginal lilac spots subapically, and 

 sometimes two or three still smaller outer-subraarginal ones subanally. 



The basal tuft of the male is very large, light reddish at base, 

 fuscous outwardly ; the outer tuft white, very short. 



Expanse of male over four inches, the female still larger. Type 

 from Sumba, where it is scarce, also occurring in Sambawa, apparently 

 unchanged. It differs from 8. leucostictos and pasithea in the pale 

 internal areas of the underside, and in the absence of most of the sub- 

 marginal spots. It somewhat resembles S. viola, Butler, from the 

 Celebes, but lacks the blue spots on the hindwing above. 



Salpinx (Selinda) elbusina, Cramer. 

 Sambawa, very common. An undescribed Isamia occurs in Sam- 

 bawa. 



2. Salpinx (Callipl(ba) sumbana, n. sp. 



Above, forewing brown, slightly glossed with blue, the outer margin 

 paler; a costal white spot, and a submarginal row of nine others, the
