94. Ornithoptera pompeus (? rectius heliacon). 



Mr. Moore does not inform us, and we have not succeeded in dis- 

 covering, in what points his Om. heli\_a\conoide$ differs from the Oni. 

 pompeus of Sikkim and Assam. 



In one of our four males from Port Blair all the submarginal black 

 spots of the posterior wings are wanting except the first or anal, which is 

 fused with the marginal conical spot as it all but invariably is in Continental 

 specimens ; in another the second spot is present on the upperside only ; in 

 a third, the second and third, and in a fourth, the second, third, and sixth, 

 while in the feminine male upon which Mr. Moore founded his Oni. 

 heliaconoides the second, third, fifth, and sixth are present on both sides : 

 all of which variations are to be met with in a sufficiently large series of 

 Continental specimens, particularly in our own fine one from the Sikkim 

 and Khasi Hills. 



Of our five females two have the anterior wings conspicuously rayed 

 with white like some Assam specimens, and three (two from the Little 

 Brother Island and one from S. Andaman) have the veins of these wings 

 either simply bordered both sides with paler black than the general ground- 

 colour or only exhibit here and there faint traces of white scales like others 

 from the southern slopes of the Khasi Hills (Sylhet). 



The males which are least differentiated from the females in point of 

 markings, also resemble them in the fuller and more broadly rounded inner 

 angle of their anterior wings. 



95. Papilio mayo.

The shape of the wings and the presence of red markings on the under- 

 side of the hinder pair prove that P. mayo is more closely allied to P. 

 androgens than to P. polymnestor ; not a single red scale being to be detect- 

 ed in the hind wing of the latter except at the base of the organ, and 

 the conspicuous blue- grey band on the upperside of the former being no- 

 thing more than an excessive development and concentration of the radiating
