that my specimens were females, though the shape of the wings should 

 have enlightened me as to their true sex. A closely allied species 

 appears to be the " Tajuria " dominus from Kina Balu, Borneo, described 

 by Mr. H. H. Druce in Proc. Zool. Soc. Lond., 1895, p. 600, pi. xxxiii, 

 fig. 12, male, but that species has the " sexual mark " on the upperside 

 of the forewing in the male more isolated, being outwardly bounded by a 

 streak of the blue ground-colour, the apex of the hindwing is more 

 broadly black; and on the underside the anal area of the hindwing is 

 much more broadly yellow, the two patches being confluent instead of 

 well separated. The shape of the hindwing also differs, it being much 

 more produced at the apex in T. dominus than in B. valentia. As Mr. 

 Druce has placed dominus in the genus Tajuria it is presumed that it 

 has three subcostal nervules to the forewing unlike valentia, which has 

 only two, though Colonel Swinhoe overlooked that fact. I had described 

 this species as new before Colonel Swinhoe's description of it was pub- 

 lished. I have, however, since received a specimen of his species from 

 him, and find that the two are synonymous, so my MS. name is of course 

 suppressed.
