The chrysalis is said to at first green, and afterwards brown. 



A variety of this species, described as a separate one under the 

 name of 'Polyommatus Alcippe,' has "the wings narrower, blue above, 

 with a broad black margin to all the wings, the under side of the 

 male of a deep greyish or drab colour; the ocelli very distinct in the 

 female, and the oblique series on the posterior wing consisting of four." 



Ill anotlicr taken by the late Mr. Haworth, and named by him 

 'Polyommatus maritimus,' "the ocelli on the disc of the under side of 

 the wings are elongated into those on the middle of the wing, being 

 almost confluent with the following row of spots." 



Another, taken by the late Mr. Hatchett, had the upper surface of 

 all the wings of a pale fulvous tawny-colour.
