sccoiulaik's, wliilst the subapical patch uii the primaiii-r^ is 

 bright brick-red, as in the brii^htcst examples of T. theoffone 

 (the dry-season lonn of T. oniphnlc). The intennediatc 

 pha&e has the bhick batidinj^ of the upper surface still weaker, 

 and below the subapical patch on the primaries and the discal 

 stripe across the secondaries are sharply detined 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. thaogoyie, and 

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

 apex of primaries and the secondaries below are bright rosy, 

 the former with difl'used bright brick-red suba|)ical patch, tiio 

 latter with the discal stripe varying trom 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 1 have ever seen in the slightest 

 degree resemble its dry-season phase. Tiiat T. pijrrhopteras 

 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 Loauda ; 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 w4iich 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
