Show 370 MR. A. G. BUTLER ON [June 5, There were several examples of this species in Mr. Forbes's collection, clearly showing that the differences of coloration are constant. 15. PAPILIO INOPINATUS, sp. n. Allied to P. adrastus of Felder, from Ceram and N. Guinea ; but the male with a broad oblique subapical white belt, which does not quite reach the outer margin and is cut by the black nervures; the fascia on the secondaries narrower, formed more nearly as in the Australian P. ageus, with zigzag outer edge, but of more uniform width throughout than in that species, and of a sordid cream-colour ; a scarlet spot near the anal angle, well separated from the central fascia. The female differs in the whiter and oblique belt across the primaries, the inner edge of which is not so deeply zigzag, and therefore is not angulated as in the allied species, and the outer half toward apex suffused with grey so as greatly to reduce its width ; secondaries with no trace of the central white patch, the submarginal scarlet spot large, oblong, and notched in front. Expanse of wings, 8 144 mm., § 153 mm. 8 var. Wings shorter ; the inner edge of the white band of primaries impinged upon by the discoidal cell, which also encloses a spot of the same colour as the band ; the band of the secondaries broader, cutting across the end of the cell. Expanse of wings 132 mm. Maroe Island. HETEROCERA. SPHINGID^E. 16. DILUDIA CASUARIN^E? Macrosila casuarina, Walker, Lep. Het. viii. p. 210. n. 19 (1856). "M. Saqueir," Larat.
