" After the fourth day the green assumes a duller and rather 

 deeper hue, and the white freckles show up in stronger contrast. 

 Some spécimens are very boldly marked with black. The colour 

 then remains unchanged for a fortnight, after which time the 

 wings assume a more ochreous tinge, and become dull orange on 

 the 2ist day; the colouring of the imago then rapidly developes, 

 changing to purplish-brovvn on the 22nd day, while the head and 

 abdomen remain dull green. The imago emerged on the following 

 day, the pupal stage occupying twenty-three days. Another, 

 which pupated May 25th, 191 2, emerged early a. m., June i/th, 

 igi2, this also being twenty-three days m the pupa.
