The white band crossing both wings is comparatively narrow, and is drawn to a point at the costa of the anterior wings, and also* as it approaches the anal angle of the hind wings. The fulvous patch at the same angle is restricted, and only surrounds the terminal ocellus. In this respect this race resembles C. leelia, Feld., and C. strigata, Feld., from both of which it differs in the pointed form of the transverse white band; beneath it resembles the race we believe to be C. strigata (exempl. in mus. nostr. ex Gilolo or Morty, Wallace), except that the white submarginal bands of the hind wings are all narrower. Two specimens of this Cyrestis are in the collection, both alike as to their markings. Though, as we have already stated, but a race of C. acilia, it seems as much entitled to separation as several other races which have had names bestowed upon them. 18. MlNETRA, Sp.? One imperfectly developed specimen of a Minetra probably indicates that a distinct race inhabits these islands ; but it may be as well to defer characterizing it for the present, until more specimens come to hand. It most resembles specimens from Bouru and Ceram, collected by Mr. Wallace, and which are doubtless referable to the Amboyna species M. sylvia (Cram. Pap. Ex. t. 43. f. F, G ) . 19. DOLESCHALLIA BROWNI. (Plate XXII. figs. 3, 4.) 2 Exp. 3*8. Allied to D. australis, Feld. (Voy. Nov. Lep. p. 405, t. 51. f. 1,2), but larger; the inner edge of the terminal black portion of the primaries, instead of running nearly parallel to the outer margin, ends at the anal angle ; a well-defined subtriangular black spot at the end of the cell: the secondaries have-the two black spots as in D. polibete, Cr., but are without either white or blue centres. Beneath there are well-defined light marks across the cell, beyond it, and in the apical angle ; the base of the secondaries has also two light spots of a violet tint ; two ocelli on the secondaries beneath correspond to the black spots of the upper surface. W e have been unable to find any species exactly corresponding to this. It differs from all we have seen, in the black of the primaries ending at the anal angle instead of on the inner margin. Both the species recently described by Mr. Butler, D. herrichii arid D. mont-rouzieri (P.Z.S. 1875, p. 612), the types of which we have examined, appear to be quite distinct from the present insect. 20. CHARAXES JUPITER. Charaxes jupiter, Butler, Lep. Ex. p. 14, t. 5. f. 4, 7. This handsome species, of which Mr. Brown has sent a single specimen, agrees well with Mr. Butler's figure cited above. Tbe original specimen was obtained by Mr. Wallace at Dorey, New Guinea. PROC. ZOOL. Soc-1877, No. X. 10 |
