tain, 6500 feet June 27th, 7400 feet June 30th; Kondowi, Lower 
Nyika, Nov. 30th, 1895; Kasungu Mountain, 5945 feet Feb. 29th, 
7425 feet March 2nd, 7200 feet March 5th, 1896. 
Most of the specimens are of the ordinary European type.

Dry-season form. 
Differs in the great enlargement of the discal series of spots on 
the secondaries, these being salmon-buff tinted in the male, and 
sulpbur-yellow in the female; the primaries in the latter sex are 
also coloured more nearly as in the male, but the salmon-buff area 
is washed with yellow; on the under surface the whole colouring 
of the male and the bands upon the yellow area of the female are 
deeper and redder.

The female contained *‘ pale orange ova” (R. C.). 
When describing the male of 7. mutans 1 compared it with 7. 
vesta (meaning the southern species usually so-called); but 7. vesta 
is an Abyssinian species, identical with 7. velleda of M. Lucas, and 
differs from the South-African butterfly in the much brighter 
colouring, with somewhat differently formed and much redder bands 
on the under surface of the secondaries: the southern species is 
only the wet-season form of 7’. argillaceus, and is T. vesta of Trimen 
(mec Lucas); the latter, on the under surface, is much nearer to 
T. aurigineus, whereas TJ. argillaceus is certainly the southern 
representative of 7. mutans.

At the last-mentioned locality Mr. Crawshay speaks of this 
butterfly as being plentiful; yet he seems only to have captured
