colouring of my acquaintance: it is probably one of the genera of a family 
peculiar to the East Indies. Little is known of the Oriental Lepidoptera, ex- 
cepting those described in the Annulosa Javanica by Dr. Horsfield, so much 
so that I hesitate in hazarding an opinion respecting them. It is almost im- 
possible to describe the beautiful colouring of this lovely insect : the dye of the 
under wings is of a rich mazarine blue, which passes insensib] y into violet and 
black. In affinity the genus is allied to Campylotes of Westwood, described in 
Professor Royle’s work on the Natural History of the Himalayan Mountains, 
It is allied also to Gymnautocera of Guerin, and to Heleona and Anthomyza of 
the same author. It is doubtful if the insects composing this family are more 
allied to the Zygænidæ than the Lithosiadæ ; they appear to have been greatly 
neglected, and it is the more remarkable, as they are certainly some of the 
most beautiful of the Lepidoptera.
