95. Teracolus catachrysops. 



Teracolus catachrysops, Butler, Ann. & Mag. Nat. Hist. ser. 5, vol. ii. 

 p. 178 (1878). 



East Africa, from the Sabaki valley southwards to Masasi. 



The wet form alone of this species has hitherto been re- 

 ceived. It is readily separable from T. mutans and vesta in 

 the small size of the submarginal spots on the black external 

 area, and in the white colour of these spots on the secondaries of 

 the female ; from T. mutans also in the greater distinction of 

 tint between the orange ground-colour and yellow apical and 

 external spots on the under surface of the primaries and the 

 deep red bands on the under surface of the secondaries, and 

 from T. vesta in the straighter character of these bands and 

 the slenderness of the innermost one. 



A female from the Sabaki valley has the ground-colour 

 above entirely white, feebly tinted with sulphur-yellow, and 

 the colouring below paler than usual. 



96. Teracolus Hanningtoni.

From the Victoria Nyanza eastward to Witu. 



This species may be distinguished at a glance from its 

 nearest ally T. catachrysops by the minute discoceliular spot 

 on the primaries, the more tapering series of spots on the black 

 external area of the secondaries, the minute subapical spots 

 on the primaries, the yellower discal colouring on the under 

 surface of these wings, and the dark veining of the same 

 surface of the secondaries. Mr. Marshall states that 

 Mr. Jackson's series shows the impossibility of separating 

 these two species ; but I have often been told similar things 

 about other butterflies, and am not inclined to accept any 

 such observation on trust, especially from a man who, though 

 a good observer, sees no difference between the illustration of 

 T. vesta and T. mutans, but speaks of both as " typical 

 specimens " *. 



97. Teracolus amelia. 



Idmais amelia, Lucas, Rev. et Mag. de Zool. 1852, p. 428. 

 Abyssinia. 

 Although more nearly related to T. Hanningtoni than to 



* I have recently examined Mr. Jackson's series, and had no difficulty 

 whatever in assigning them to their proper species.
