SUPPLEMENT. 



Genus CORYDON. 



Corydon, Boisduval, MS. 



Head of moderate size : eyes smooth. Palpi thickly covered with hair, closely embracing 

 the head, the terminal joint unfortunately broken off. Antennae gone. 



Wings as represented on the plate. 



Legs as figured, a fore leg, b hind leg : the tarsi of the fore legs thickly armed with a 

 double row of spines. 



I would scarcely have ventured to place this very remarkable Butterfly amongst the 

 Lycsenidse without better authority than my own, although I have very little doubt that it 

 belongs to this family. Professor Westwood has, with his usual kindness, examined it for me, 

 and expresses himself quite satisfied that this is its proper position. It has, as most of the 

 African Lycamidae have, four branches from the subcostal nervure, and in no way differs in its 

 neuration from Epitola Elion, except that the cell of the posterior wing of that species is 

 closed somewhat more obliquely. 



Oorydon Boisduvalii, Hewitson. Plate I. 



Upperside dark rufous-brown. Anterior wing crossed obliquely beyond the middle by 

 a band of white, divided into five parts by the nervures : the anal angle broadly blue. Pos- 

 terior wing blue from the discoidal cell to the outer margin : the apex white. 



Underside pale yellow. Anterior wing with the basal half, except the costal margin 

 and the anal angle, dark brown, black where it touches the costal margin and marked with 

 three spots of silvery blue : the costal margin and the apex with the nervures and lines 

 between them dark brown. Posterior wing with a large spot of orange-yellow on the costal 

 margin bordered outwardly and on the margin with black and two black spots, and radiating 

 from it five bands of dark brown : two near the base, the third not reaching to the inner 

 margin, the fourth extending to the anal angle, the fifth short ; between the third and fourth 

 of these bands there is another short band : some of the nervures towards the outer margin 

 and lines between or on each side of them (some of them united at the top and on the margin) 

 dark brown : a spot of black near the apex. 



Exp. 2| inch. 



In the Collection of Dr. Boisduval, from the Gaboon. 



It is with very great pleasure that I have dedicated this very remarkable species to Dr. 



Boisduval, mingled, however, with regret that I cannot better express my estimation of the 



extreme kindness and liberality with which I have always been treated by him.
