This species closely resembles in its colouring P. Ridleyanus, 

 and some of the Acrcece near to A. Zidora. For the first time I 

 have deviated from a rule I had laid down for myself, never to 

 name an insect after any living entomologist, or even after any 

 entomologist whatever ; but having, in accordance with the law of 

 priority, converted into a synonym the name oiBoisduvalii, given 

 to an Adolias by Mr. G. R. Gray, I have as a compensation de- 

 dicated this beautiful insect to my excellent friend, whose kind- 

 ness and liberality to me in placing at my service his books, ma- 

 nuscripts and collections has been beyond all praise.
