secondaries, whilst the subapical patch on the primaries is 

 bright brick-red, as in the brightest examples of T. theogone 

 (the dry-season form of T. omphale). The intermediate 

 phase has the black banding of the upper surface still weaker, 

 and below the subapical patch on the primaries and the discal 

 stripe across the secondaries are sharply defined and very 

 vivid upon a creamy ground-tint ; the fringes rosy : the 

 (typical) dry-season form retains the black internal stripe on 

 the primaries, which is absent in males of T. theogone, and 

 still shows a trace of the discal stripe on the secondaries; the 

 apex of primaries and the secondaries below are bright rosy, 

 the former with diffused bright brick-red subapical patch, the 

 latter with the discal stripe varying from brick-red to gravel- 

 brown. 



I cannot agree at all to Mr. Marshall's arbitrary decision 

 that this localized form is inseparable from T. omphale^ no 

 examples of which that I have ever seen in the slightest 

 degree resemble its dry-season phase. That T. pyrrhopterus 

 and T. omphale had a common origin will not be disputed, 

 but that they are now distinct I firmly believe.

On the west of Africa this species ranges from Sierra Leone 

 to Old Calabar and the Cameroon Mountains ; it reappears 

 at the Cape, and extends up the east side of Africa as far as 

 Natal. We have one almost typical example from the West 

 Coast as far south as Loanda ; therefore, although the species 

 is represented in S.W. Africa by T. ocale, the latter can 

 hardly be regarded as more than a climatic race. On the 

 other hand, the northern T. epigone appears to be geographi- 

 cally separated from T. evippe, and, though nearly allied, 

 must be regarded as a distinct species. T. pseudocale is a 

 starved southern variety of the wet-season phase. 



The females of the typical wet-season T. evippe vary con- 

 siderably in ground-tint and in the character of the apical 

 patch ; the rarest form of the female is that which most 

 nearly approaches the south-western race, with white ground- 

 tint and the black apical patch of the primaries enclosing a 

 clear orange arched band ; a second less rare form has this band
