considerably towards the posterior margin. This 
example was found at OfFack. 
The Priam butterfly is found in the islands of 
Amboina, Rawack, and Ceram. It has been ob- 
served to hover about the Mangifera Indica in 
preference to other trees, and it has hence been 
conjectured that it deposits its eggs on the leaves, 
and that they constitute the food of the caterpillar. 
It never occurs in large numbers, and is hence 
somewhat rare in collections- Specimens of both 
sexes are preserved in the valuable collection of in- 
sects belonging to the Edinburgh University Mu- 
seum.
