506 Revision of the Genus Teracolus, Swains. 
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 7. 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 7’. 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 7’. 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 Hanningtont. 
3b Q. Teracolus Hanningtoni, Butler, Ann. & Mag. Nat. Hist. ser. 5, 
vol, xii. p. 104 (1883).

From the Victoria Nyanza eastward to Witu. 
This species may be distinguished at a glance from its 
nearest ally 7. catachrysops by the minute discocellular 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 ” *,

* T have recently examined Mr. Jackson’s series, and had no difficulty 
whatever in assigning them to their proper species. of
