We now pass to another group of Butterflies, called the 

 Danainae, several examples of which will be figured, and others 

 will be mentioned or briefly described. 



On Plate XIII. Fig. 1 is shown a large Butterfly called Eestia 

 Idea. This genus is rather a large one, and as all the species 

 are of very similar colouring, and there is a great tendency to 

 variation, it is not at all easy to distinguish between the species. 

 Mr. Westwood has figured several Hestias in his "Oriental 

 Entomology," and comments upon the difficulty of distinguish- 

 ing between a species and a variety. Speaking of Hestia Jasonia, 

 a Cingalese insect, he makes the following remarks, which are

 sive series of specimens of these insects from different localities)
