 Besides the fine and beautiful insect described below, there are repre- 

 sented in the Zoological collections formed by Mr. Ossian Limborg and staff 

 in Upper Tenasserim during the months of December, 1876 and January, 

 February, March, and April 1877, 225 other species of Lepidoptera, partly 

 butterflies, 50 to 60 of which are considered to be undescribed, and several of 

 which are referred to new genera, by Mr. F. Moore, who has worked out 

 the whole collection and written a paper upon it which will shortly be pub- 

 lished and illustrated by three or four coloured plates in the Proceedings of
