Male. — Very similar to thai o^ T. jo/u/sfo/ii, but the golden yellow apical patch on 

 the primaries seems to be more reduced in size and has a more violaceous gloss ; the 

 white spot between the second and third median nervule is nearly obsolete, being 

 entirely absent in some specimens ; the white central area is not so much toothed as 

 in T. jolinsioni. The secondaries are similar in colour to those of the latter species, 

 but the broad black costal border extends more towards the middle of the discoidal 

 nervule. 



Underside. — Not to be distinguished from that of T.jo/insfoni. Expanse 1 "10 inches- 



Female. — Having the same markings as in the corresponding stage oi T.jo/i/isfo/u\ 

 but the general colour is sulphur-yellow instead of white. The sub-marginal row of 

 spots on the secondaries appears to be more pronounced than in T.johnsfoni. 



Underside. — Rather lighter than the upper surface, the primaries being marked like 

 those of tlie male. Secondaries similar to the primaries in colour, liaving the deep 

 orange streak along the costal margin and a distinct discal row of small spots 

 situated between the nervules : these are generally absent in the females of T. johnsfoni, 

 although occasionally faint indications of them ma}^ be observed. Expanse 2'1 inches. 



The type of T. abyssinicus, Butler (Fig. Id), is of a much deeper yellow than the 

 ordinary " wet-season "■ female and the brown markings are much heavier in every 

 way, the pale spots near the apex being almost obsolete, and the brown on the inner 

 margin also deeper in colour and more suffused over the base. On the secondaries 

 the nervular spots unite, thus forming a distinct hind-marginal border ; the base is 

 also more heavily dusted. The underside is very similar to that of the example 

 from Abyssinia figured (Plate 9, fig. Ic), the general colour being a little 

 deeper yellow, the nervules of both wings terminating in dark spots. Expanse 

 2'1 inches. 



"Dry-season " FORM. — Only represented b}^ one specimen in the British Museum, 

 and is apparently T. fafnia of Felder. The apical ])atcli on the primaries 

 is tawny brown as far as the first median nervule. There is also a row of disconnected 

 discal spots, the inner margin being entirely white. A few of the specimens in Mr. 

 Rothschild's collection from East Africa show a very faint indication of the usual 

 dark streak along the inner margin. Tlie secondaries are entirely without 

 spots. 



Underside. — The whole of the primaries white with the exception of the apex and
