The spots near the apex of the wing are white, not fulvous, and are situated further from the costa than in Hombron and Jacquinot's plate. The specimen is not in good condition ; and the examination of more examples may prove that the species is really distinct from any of those above mentioned. 13. JUNONIA VELLIDA. Papilio vellida, Fab. ; Donov. Ins. N. Holl. t. 25. f. 3. A single specimen of this widely ranging species is in the collection. 14. CETHOSIA OBSCURA. Cethosia obscura, Guer. Voy. Coq. Zool. p. 277, t. 15. f. 4 (New Ireland). Mr. Brown has sent two specimens of this rare species, which we believe has not been obtained since the voyage of the ' Coquille,' when specimens were taken at Port Praslin in New Ireland. 15. DIADEMA INEXPECTATA, sp. n. 6* Exp. 3*4. Allied to D. alimena (Li), but differing in the much narrower band of blue which traverses both wings, and which becomes nearly obsolete as it turns towards the costa of the fore wings ; beneath the fore wings are devoid of the blue patch which traverses the median nervules, the apex of the wings is darker, and an oblique band of spots which passes from the costa to beyond the cell is evanescent; the hind wings show only traces of the pale transverse band of D. alimena, and the submarginal spots are much larger; the basal portion of both wings is deeper red-brown. The specimens of the widely ranging D. alimena are all fairly constant in their characters; and from them the male specimen in Mr. Brown's collection differs in the above particulars. 16. DIADEMA UNICOLOR, sp. n. (Plate XXIII. figs 1, 2.) 8 Exp. 3*6. Above uniform dark brown ; the margin of the secondaries hardly paler, with a narrow black submarginal line ; a row of minute bluish spots parallel to the outer margin of both wings : beneath slightly paler; three bluish spots in the cell near the subcostal nervure, and a distinct row parallel to the outer margin; a marginal dark band with a central lighter band surrounds the outer margin of both wings. Allied to D. perryi, Butl. (P. Z. S. 1875, p. 613, t. 67. f. 3), but differing in the uniformity of the colouring of the upper surface and the reduced size of the submarginal spots of both wings, and other characters. This species seems to be separable from any yet described. We compared it with the type of D. perryi, and found that Mr. Brown's specimen differed in several particulars. 1 The former of the last-named species is distinct from the latter, though placed together by Kirby (Cat. Lep. p. 192), as is quite apparent from a comparison of the two sufficiently accurate figures. |
