Ambukol. 



I much doubt whether this female would not be better placed next 

 to T. halimede, of which Klug says it may be a variety ; it is, I 

 should say, more probable that it is the female of T. pleione than a 

 variety of T. halimede.

5 Anthocaris (sic) eupompe, Lucas, Lep. Exot. pi. 36. fig. 4 

 (1835). 



Underside like T. cinerescens, but without the blackish line across 

 the cell of primaries or the orange costa to secondaries. Expanse 1 

 inch 9 lines. 



$ . Very like Klug's figure of T. acaste, but larger and darker, 

 the apical area of primaries greyish brown, crossed by a curved series 

 of whitish lanceolate streaks, bounded on the inside by black spots. 

 Wings below like the male of T. cinerescens. Expanse of wings 2 

 inches.

 This species is a link between the T.eupomp>e&\\(\. halimede groups.

The female forms a link between the T. -eupompe and antevippe 

 groups. It is the Anthocharis eupompe, var., of Trimen (Rhop. 

 Afr. Austr. p. 46), but it is ticketed " Seneg.," not S. Africa. The 

 long description is taken from an Indian species, there being no 

 African butterfly to which it will apply.
