forms, and to the fact that typical specimens occur throughout 

 the eastern side of Africa, I think it advisable to regard them a,s 

 merely synonyms of one variable species. T. vesta ranges practi- 

 cally through the whole of Tropical Africa, but south of the Tropics 

 it does not occur westward of the Transvaal and Natal. 



21. Tekacolus ANSonGEi, sp. nov. 



c^ . Upperside bright ochreous with black markings. Fore wing : 

 Pattern and colouring similar to that ol: T. cmr'ujineus, Butl., except 

 in the following points : («) there is no trace of the whitish-grey 

 patch at base, it being replaced by slight blackish clouding; (h) the 

 discal zigzag black band is narrower and ends abruptly on inner 

 nervure, instead of being continued to, and suffused along, inner 

 margin. Neuration more finely black throughout. Hind luing : 

 Ground-colour as in fore wing, base with very slight fuscous 

 clouding, and a curved dentate baud across disc of same colour as 

 basal clouding, much lighter than same feature in T. aurigineus, 

 and continuous, not macular ; a broad black hind-marginal baud, 

 containing inter-nervular dots of ground-colour. Neuration black 

 beyond middle only. 



Underside. Pattern exactly lilve that of T. vesta, Eeiche. Fore 

 iving : Grround-colour somewhat lighter than above ; discocellular 

 spot distinct, smaller than above ; zigzag discal band of upperside 

 reproduced, but macular, being divided by nervules which are dark 

 pink in colour, near costa the band assumes a brownish tinge ; 

 beyond this a row of yellow spots, large below first median nervule 

 and of same colour as base, but above it they are smaller and of a 

 pale yellow tint ; beyond this a narrow curved brownish line, 

 which is succeeded by a hind-marginal row of subquadrate pale 

 yellow spots, which diminish towards posterior angle. Hind wing : 

 Pale yellow, with basal half of costa and a ray along inner nervure 

 ochreous yellow. A longitudinal ray from base in cell and a 

 shorter one above it deep pink ; an irregular transverse band of 

 the same colour passing through the extremity of discoidal cell, 

 then a band of ground-colour and a discal angulated brownish-pink 

 band about middle of wing ; then another broader band of yellow, 

 divided into spots by the intersecting pink nervules ; beyond this 

 a narrow curved line of brownish pink, and finally a hind-marginal 

 row of subquadrate spots of ground-colour. A thin black line 

 runs along extreme hind margin of both wings, which is present 

 in T. vesta but absent in T. aurigineus. 



Female same as the male, but the colouring duller on both surfaces. 



This is a most interesting species, combining as it does the 

 upperside colouring of T. aurigineus with the underside colouring of 

 T. vesta, being at the same time quite distinct from either species. 

 Prom the former it may be at once distinguished by the complete 

 absence, in the male, of the basal white patch in fore wing, and 

 the great reduction of the black discal band in the hind wing, but 

 the underside is hardly distinguishable from some specimens of 

 the variable T. vesta (more particularly of the T. ^nutansiorm).
