'AN ELUSIVE PAPILIO.' 



This photograph is from a coloured drawing made by Mr. T. A. 

 Barns from memory. It represents a species of Papilio of which two 

 specimens were seen by Mr. Barns in the district of the Upper 

 Congo. A similar species, but probably identical, has been reported 

 from Liberia. 



No specimen has been obtained of this insect, and it must be 

 exceedingly rare. We reproduce Mr. Barns' drawing in the hope 

 that entomologists in Africa will look out for the insect. We should 

 be glad of any reports from anyone who has seen it. 



The band on the fore wing is of a brighter blue than in zalmoxis, 

 and the coloration of the hind wing is similar to that of antimachus.
