wings, and a slender black tail, tipped with white, appears to be 

 a continuation of vein 2. The under' side is grey-brown, with 

 numerous white wavy lines and broader streaks ; there is a 

 whitish band on each wing before the outer margin, and black 

 spots as above, but these are ringed with metallic blue. 



I have not seen any of the early stages of this butterfly. The 

 caterpillar, which feeds upon the green seeds in pods of the 

 Leguminosae, including the garden pea and the lupine, is 

 figured on Plate 102. It is described as being green or 

 reddish-brown in colour, with a dark stripe on the back, double 

 oblique lines on the sides, and a white line below the yellow 

 spiracles ; head black. The chrysalis is of a red or yellowish 

 colour, and dotted with brown. It has a silken girdle and is 

 said to be attached to a stem, as shown in the figure, but pro- 

 bably it is more often fixed up among the withered leaves of the 

 food-plant. Two of the earliest known British specimens of 

 this butterfly were taken by the late Mr. Neil McArthur on 

 August 4th and 5th, 1859, on the Downs at Brighton ; the third 

 example was captured by Captain de Latour at Christchurch, 

 where it was flying about a plant of the everlasting pea in his 

 garden on August 4th of the same year. Newman has noted 

 that in that particular year the butterfly was very abundant in 

 the Channel Islands and on the coast of France. No other 

 specimen seems to have been observed in England until 1879, m 

 which year one was taken at Freshwater in the Isle of Wight 

 on August 23rd. In 1880 a specimen was captured in a garden 

 near Bognor, Sussex, on September 12th. On October 2nd, 

 1882, one was obtained at West Bournemouth. Three were 

 netted in 1893, one of these in late August, and one in the third 

 week of September, both in Sussex ; the third was taken in 

 Kent (inland) in September. In 1899 a specimen was found at 

 Winchester on September 1st, and one at Deal on the 16th 

 of the same month ; each of these, curiously, was sitting on a 

 window. On August 2nd, 1904, one example was taken in a
