Rev. F. W. Hope o;? so7ne »e«' Insects collected in Assam. 447 



The above insect is one of the most lovely in colouring of all the Lep'idoptera. 

 When viewed by individuals standing in a different light, the blue appears to 

 one j»erson to be of a vivid green, to another of a lazulite blue. I have had 

 drawings made by different persons ; the first contends that the colour is green, 

 and the second that it is blue; in short, both are right; all depends on the 

 situation in which the individual views the specimens.
