Ehanda (August-September). Two male examples. 



94. Teracolus antevippe (Boisd.). 



S 2 . Anthocliaris antevippe, Boisd. Sp. Gen. Lep. i. p. 5/2, 

 pi. 18. f. 3 (1836). 



Omaramba-Oamatako (January). One male example. 



This male is a very fine individual, in perfect condition, and 

 larger than any that 1 have previously measured (exp. 2 in. 1 line). 

 There is only a very minute trace of black on the middle of the inner 

 edge of the apical bright red patch of the fore wings, and the hind- 

 marginal nervular black marks in the hind wings are sufficiently 

 large to be contiguous, and so to form a very sharply dentated 

 narrow border. On the pure white underside, the nervules of the 

 hind wings and of the apical half of the fore wings are blackish 

 near the hind margin, as in those examples of T. achine (Cram.) 

 which are mentioned in my ' South- African Butterflies ' (iii. p. 133), 

 as inhabiting the Transvaal and the Eastern South-tropical tracts. 



95. Teracolus achine (Cram.).

 (1781;. 



Humbe (October), Okavango River (December), and Omaramba- 

 Oamatako (January). Five female examples. 



All these specimens exhibit on the white ground of the fore wings 

 a shght tinge of yellow immediately before the inner edge of the 

 orange apical patch ; they approach the form gavisa, Wallengr., in 

 their upperside marking of the fore wings, but (with the exception 

 of one from Omaramba-Oamatako) are not nearly so heavily marked 

 on the hind wings. Ou the underside, three of the five have the 

 nenration in parts very finely marked with blackish, which is also a 

 feature indicating approach to gavisa. They agree very nearly with 

 specimens collected on the Marico River Cin 1883) by Mr. F. C. 

 Selous, and at the junction of that river with the Limpopo (in 1887) 

 by Mr. Eriksson, and tend to strengthen the view that gavisa is not 

 truly separable from T. achine.

Omrora (August). One male example. 



The Angolan specimens on which this species was founded were 

 two taken by the late Mr. J. J. Monteiro, respectively at the Quanza 

 (August 1872) and Ambriz (October 1872). The species belongs 

 to the group of which T. daira, Klug, is representative, its nearest 

 ally being the Angolan T. interruptus, Butl., which is larger and 

 has the black markings more developed. The male T. gelasinus
