This very interesting specimen was exhibited at a 

 recent meeting of the Entomological Society (Proc. Ent. 

 Soc. 1869, p. viii); Mr. McLachlan informs me that the 

 same form exists in the collection of Mr. Bond, but as it 

 seems never to have been described or figured, it is high 

 time that some notice should be taken of it. I caught 

 the insect on a slope facing the Mt. Blanc range, where 

 it was flying about in company with male specimens of 

 Aglaia and Niohe ; these two forms are constantly together, 

 vary into one another, chase one another about, and show 

 every sign of being one and the same species.
