variety of Ornithoptera Brookiana. 77 



markings of metallic green, and the slighter outer ones 

 of dusky pencilling, and there is also a narrow blue line 

 along that part of the upper margin of the wing nearest 

 the body. This line may be observed both in the type 

 female and in the variety also ; but the point in which 

 the sexes differ, as regards the blue markings, is that 

 both females have a parti-coloured patch in the upper 

 segment of the anterior wing, golden green towards the 

 outer and blue towards the inner surface, which is 

 altogether wanting in the male ; and also that on the 

 anterior wings of this variety the blue markings pre- 

 dominate, while on those of the ordinary female there 

 is rather more metallic-green. This specimen, which is 

 unfortunately rather worn, and has lost its antennse, 

 does not differ from the type as regards the red neck 

 collar, or in having, as Hewitson phrases it, " the body 

 belted twice with crimson,"
