ILIADES. 299 



It is bronzy-green, with a broad sub-marginal band of green 

 streaks on the fore-wings ; the hind-wings have a large blue 

 patch, dentated on the outer side, before the tip, and two large 

 red sub-marginal crescents on each side of the base of the tail. 

 [LXV. A-C.] Iliades, Hiibner. This genus includes a number 

 of large and handsome Butterflies, most of which measure five 

 inches in expanse of wing. They are extremely characteristic 

 of the Indo- and Austro-Malayan Regions. I have figured the 

 female of one of the commonest species.

This species belongs to a small group of closely- allied forms 

 in which the males are almost all alike, and the females differ 

 greatly. Boisduval united them all under one species, to 

 which he applied the name of Papilio memnon ; but Dr. 

 Wallace ("Trans. Linn. Soc. Lond." xxv. pp. 46, 47) recognised 

 two species, with polymorphic females. More recent authors 

 (Messrs. Butler and Distant, for example) are inclined to 

 recognise a larger number of species, thinking that it will be 

 found possible ultimately to separate the males into species as 

 well as the females. It is a parallel case to that of Papilio 

 merope^ Cramer, which we have already noticed (anteci, p. 291). 

 The present species belongs to the group of forms which are 

 peculiar to continental India, and to which Dr. Wallace applied 

 the name of Papilio androgeos, Cramer. They differ from the 

 forms found in Java, Sumatra, Borneo, and Lombock, in
