 It is hardly necessary to say more of this insect than that 

 it is generally common throughout the Palsearctic Region, 

 frequenting fields and gardens, and that there is a succession 

 of broods throughout the year. There is a permanent form in 

 the Canary Islands, P. cheiranihi (Hiibner), with larger and 

 confluent black spots on the wings ; and forms intermediate 

 between this and the ordinary type occ ir in the Himalayas 

 {P. nepalensis^ Gray) and in Madeira {P wollasloni, Butler). 

 It is an insect of fairly strong flight. 



This Butterfly generally measures from wo and a half to 

 two and three-quarter inches across the wing , which are wliite 

 above, with a black triangular patch, somew "-^t indented on 

 the inner edge, at the tip of the fore-wings. There is also a 

 rather large spot on the costa of the hind-wings towards the 

 tip, and in the female there are two large spots on the disc of 

 the fore-wings, and a black streak about the middle of the 

 inner-margin. On the under side both sexes are nearly alike ; 

 the colour inclines to yellow, especially on the hind-wings.
