Hist. ser. 6, vol. iii. p. 318 (1889). Kina Balu ( Whitehead). Mr. Grose Smith states that this species is nearest to S. cinesia, Hew., and S. maneia, H e w . The type is in Mr. Whitehead's collection. I have not seen a specimen, but it would appear to be quite distinct. S. cineas, Hew., and S. maneict, Hew., are, howr-ever, not allied to each other. BlDUANDA HEWITSONII, Sp. n. Mgrina cinesia, 2 > Hew. 111. Diurn. Lep., Lye. p. 29, pi. xii. fig. 20 (1863). 2 • Allied to B. cinesia but smaller ; upperside with the white band rather narrower and divided by brown nervules. Underside ochreous yellow, darker and richer in colour, tbe inner black band on the hind wing narrower and not so much waved; the outer black band also is straighter and is without the distinct black tooth which is so conspicuous in B. cinesia. Middle tail considerably longer. Expanse ly1^ inch. Elopura (Pryer) (Mus. Druce); Labuan ( Waterstr.). The specimen described above was taken by Mr. Pryer in March and agrees exactly with Hewitson's figure, no. 20, plate xii., which, now that we have the correct female of his B. cinesia, requires a name. B. hewitsonii should be easily distinguished from B. cinesia on the upperside by the white band on the hind wing being crossed by brown nervules. The male is unknown. Dr. Staudinger has sent me two females, and Mr. H. Grose Smith possesses one specimen, also a female. BIDUANDA STAUDINGERI, sp. n. (Plate XXXIV. figs. 5 cf, 6 2 •) cf . Upperside-fore w ing dark purplish blue, outer margin narrowly and evenly black, costal margin very narrowly black; cilia black. Hind wing dark purplish blue, costal and outer margin down to third median nervule narrowly and evenly black ; anal third, including tails, cream-wdiite, with a black baud beyond its middle divided by the nervules, extending from the second median nervule at the point at which the wing is dentated to the lobe, the inner edge of the white area being sinuous ; cilia along costal margin and apex pale yellowish, rest of wing white. Costal fold bluish grey. Underside pale brown, darker towards apex and outer margin of fore wdng, palest towards anal angle of hind wing; a faint wavy dark line in fore wing beyond the middle, commencing |
