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.
