"Fairly common, but not an easy insect to take; a fast flier 

 and a desperate donbler " {R. C). 



The single example sent belongs to the wet phase, which differs 

 from the dry phase in the better defined, browner, and much 

 darker bands on the under surface. This chai'acter, apart from 

 other differences, amply serves to prove its entire distinctness 

 from T. mutans of Southern Africa, whilst at the same time it 

 indicates some relationship to T. protomedia.

Rather a curious male, having a wet aspect on the upper surface, 

 but the under surface characteristic of a late intermediate phase, 

 the black veins being feebly indicated.

The wet phase of this species, of which we received a male from 

 Fwambo in 1897, is not very unlike that sex of P. falheiisteinii, 

 but has the costal margin of the primaries shorter and the outer 

 border more interrupted, represented only by spots at the 

 extremities of the first and second median branches ; the costal 

 margin of the secondaries below is deep orange. Expanse of wings 

 t)0 millim. 



The intermediate phase, of which (as well as of the male dry 

 phase) we received sexes in 1889 from Tanganyika, differs in the 

 reduction of the width of the outer border in the male and 

 the paler under surface. The female is bright orange, redder at 

 the base ; the primaries with a marginal series of rather large 

 greyish spots becoming black externally, and a similar smaller 

 spot on the disk beyond the middle of the second median 

 interspace ; the secondaries with smaller black marginal spots at 

 the extremities of the nervures : below, all the spots are small and 

 black, and there are five tiny squamose spots across the disk of 

 secondaries parallel to the outer margin : body blackish above, 

 whitish below. Expanse of wings, 6 63 millim., $ 61 millim. 



The dry phase (now sent by Mr. Crawshay) is smaller ; the 

 marginal blackish border of the male primaries is reduced to more 

 or less connected spots, the number of black spots on the secondaries 

 is reduced, and on the under surface those of the primaries are 

 absent, whilst the orange costal border of the secondaries is
