pupa is yellowish. Another and very similar species of this 

 group is O. rliadamaitihus^ Boisduval, which is found all over 

 India, South China, and Indo-China. For this species and its 

 allies, the name Fachliopfera^ Reakiit, may be retained, if they 

 are generically distinct from OrnitJioptera^ the type of which is 

 O. Jielena (Linn.). Other yellow species, such as O. mficollis, 

 Butler, from the Malay Peninsula, have a red collar ; others, 

 like O. ampJirysus (Cramer), have the fore-wings more or less

rayed with yellow in the males ; and the male of one species, 

 O. ?iiagclla?iiis, Felder, from the Phili[)pines, exhibits a won- 

 derful iridescence of the most delicate pale silvery blue or 

 green over the golden-yellow hind-wings. This is quite uni^pie 

 in the group, though something resembling it is seen in some 

 South American Butterflies belonging to the genus Prianiides 

 in the Eqtiitince^ and to the genus Euselasia in the Lemoniiche. 

 Even Mofpho sulkoivskyi will not compare with OrfiilJioptera 

 magellanus for metallic beauty.
