wing. According to the late Mr. Jenner Weir, the orange spot 

 extends to the hinder angle in Continental, but not in British, 

 specimens. On the hind-wings the markiiigs of the under sur- 

 face show indistinctly through. On the under surface the orange 

 spot of the male is smaller, and the tip of the fore-wings, and 

 the whole of the hind-wings are of a bright green, dusted with 

 yellow and mottled with white. The antennce are white, ringed 

 with dusky. 



The larva is green, slightly pubescent, very finely dusted with 

 black, and with a white lateral stripe. It feeds on Caj-daniine 

 iinpaticns and various other cruciferous plants in July. The 

 pupa is greenish-yellow, and is remarkable for its curious 

 boat-shaped form, thick in the middle, and pointed at both 

 ends. 



I append full particulars of one or two forms generally re- 

 garded as mere varieties of E. cardamines^ but which some 

 authors consider to be distinct species.

 Ochsenheimer remarks, respecting this insect: "A very small 

 aberration, from Italy, is distinguished by having the central 

 spot on the edge of the orange-coloured spot, whereas in 

 F. cardaniines it is placed within it. I have seen both sexes 

 under the name P. iurritis in the collection of the Abbe 

 Mazzola." 



In the first edition of my "European Butterflies and Moths" 

 I treated this insect as a distinct species, on the strength of in-
