 (1833); and {Terias fl.) Sp. Gen. Le'p. i. p. 671. n. 29 (1836). 



Omrora (August and November), Ehanda (September), and 

 Humbe (October). Eight examples ; six males and two females. 



Mr. Eriksson's specimens all show a difference from more southern 

 examples in having the apical portion of the black border of the 

 fore wings v^ith a more prominent inward projection, so as more to 

 resemble the corresponding markings in T. butleri, mihi. Moreover, 

 two of the males taken in the summer at Humbe and Omrora 

 respectively approach T. butleri in the absence of the usual under- 

 side markings; and another male from Omrora (November) has 

 the same markings only slightly developed.

Ehanda (September). One female example. 



It is with some doubt that I refer this specimen to the species 

 named, as on the upperside it has the fore-wing border considerably 

 narrower apically, and the hind-marginal nervular marks reduced (as 

 in T. desjardinsli, Boisd., § ) to dots, while on the underside there 

 is a decided rufous tinge over the margins of the hind wings and 

 the apex of the fore wings and the ordinary inarkings are obsolescent. 

 Except in its being narrower apically, the fore-wing border agrees 

 with that in the female T. regularis ; and altogether the specimen is 

 intermediate between this form and the closely-allied T. desjardinsii.

Omrora (August) and Humbe (October). Three examples; 

 two males and a female. 



The two ( S and $ ) specimens from Omrora are markedly 

 smaller than usual ; but the Humbe example is of full size.
