370 MR. A. G. BUTLER ON [JunC 5, 



There were several examples of this species in Mr. Forbes's col- 

 lection, clearly showing that the differences of coloration are con- 

 stant. 



15. Papilio inopinatus, sp. n. 



Allied to P. adrastus of Felder, from Ceram and N. G-uinea ; 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. cegeus, 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 there- 

 fore is not augulated as in the allied species, and the outer half to- 

 ward 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 A\'ings, 

 c? 144 mm., 5 153 mm. 



S var. Wings shorter ; the inner edge of the white band of pri- 

 maries impinged upon by the discoidal cell, which also encloses a spot 

 of the same colour as the baud ; the band of the secondaries broader, 

 cutting across the end of the cell. Expanse of wings 132 mm.

The specimen is so much rubbed that it is impossible to be sure 

 that it is the same as the Australian species.
