BRITISH BUTTERFLIES 



and throughout July it may be seen .f(racefully sweeping through 

 the trees and undergrowth of woods, often setthng down on a 

 favourite flower for a short time. So strong is its flight that it is 

 useless to attempt to pursue it for any distance. Sometimes it will 

 sail along a wooded path, followed at short intervals by others of 

 its species, and may be taken in the net as it passes. But perhaps 

 the most successful method of netting Paj^hia is to wait till it 

 has settled, and then secure it by a quick upwaixl or side stroke 

 of the net. If then you miss your aim, off it will dart, sailing 

 over the tree tops till, in a very short time, it is quite out of 

 sight.

orange-brown ground is carefully marked. There is a considerable 

 difference between the male and female of this species. The figure 

 on Plate III represents the male. The female does not possess 

 the broad black lines that follow the course of the veins of the fore 

 wings ; the basal portions of all four wings are also tinged with a 

 rich olive -brown colour, often with a decided tendency' to green ; 

 and the black spots of all the wings are larger. 



The under side is pai'ticularly rich in its decorations. The front 

 wings are of the usual orange brown, chequered with black. The 

 hind wings are partly brown and partly- orange, and exhibit beautiful 

 greenish reflections. They have also two bars of silver, and a silvery 

 spot in the basal angle, all with rather indefinite outlines.
