Labuan {Low and Waterstr.). 



Dr. Staudinger has sent me his type, male, for examination, and 

 I find that Bornean specimens are identical \^-ith it. B. phocas is 

 perhaps nearest to B. isabella, Feld., but the hind wing is less 

 produced apically, and the cyaneous patch extends dowTi to the first 

 median nervule, and besides the black spot in the lobe there is 

 usually a rather large black spot in the first median interspace 

 close to the margin. The female on the upperside is rich cupreous, 

 and on the underside the bands and spots are pale reddish brown. 

 It is as much worthy of specific distinction as any other species in 

 the genus. Messrs. Godman and Salvin's collection contains 

 j5. phocas from Celebes and from the Philippine Islands.

Dr. Staudinger has sent both sexes from Kina Balu, the male 

 being identical with Horsfield's type in the British Museum. I 

 quite fail to see how iS'. amba, Kirby, can be distinguished from 

 S. nasaJca, and in my opinion should be placed as a synonym of it. 

 Mr. Doherty (J. A. S. B. vol. Iviii. 1889) has possibly mistaken 

 the next species {S. amata) for S. nasaha, as the whole of the hind 

 wing of that species, except the basal portion of the costal margin, 

 is cyaneous.

 by the subcostal nervure, being paler and of a decided violaceous 

 shade, and not resplendent when held at an angle. The hairs which
