hinder wings corresponds to the surface, but the 

 green is of a more golden hue, and the circular spots 

 larger, and seven in number. The antennae, head, 

 and thorax, black — the latter with a central line 

 and two posterior spots of golden green; breast 

 spotted with red on the sides ; abdomen bright 

 yellow. 



The female is considerably larger, frequently 

 measuring nearly eight inches between the tips of 

 the wings. The prevailing colour is dark brown, 

 deepening towards the extremities of the wings ; 

 the upper pair traversed by a macular band of im- 

 pure white, the spots unequal and generally inter- 

 rupted or notched ; the hinder pair having a curved 

 row of six large wedge-shaped spots behind, of a 

 whitish colour powdered with black, the base tinged 

 with yellow, and each with an orbicular black spot 

 in the centre. Head and thorax entirely black, the 

 abdomen whitish yellow above and deep yellow 

 beneath. 



Varieties of both sexes have occurred, for there 

 seems little reason to doubt that the insect figured 

 by Guerin {Voyage de la Coquille, Ins., pi. 13, fig. 

 1 and 2) under the name of P. urvillianus, is a 

 variety of the male, while a female variety is de- 

 scribed by Boisduval*. In the former, the green 

 of the superior wings is replaced by violet-blue of a 

 very brilliant tint, and in the hinder part that colour 

 runs in a broad stripe along the nervures, dilating
