Its range, therefore, coincides with that of many birds which 

 mark the South African Region as defined by Dr. Bovvdler 

 Sharpe.

The type of this genus (with which Anthopsyche, Wallengren, 

 referred to under Callosune, is probably synonymous) is a 

 female Butterfly figured by Cramer, from Sierra Leone. It 

 may be a variety of a common West African Orange-Tip 

 figured by Drury as Papilo arethusa (Drury, 111. Exot. Ent. ii. 

 pi. 19, figs. 5, 6), but does not quite agree with any specimen 

 at present in the British Museum.

This Butterfly measures i^ inches across the wings, which are 

 dull white, stained with ferruginous towards the base. The fore- 

 wings have a rather broad umber-brown border, a small black 

 discoidal spot, and some large black spots on the inner-margin, 

 which are continued on the hind-wings in an irregular row 

 on the disc. The border of the hind-wings is composed of 

 rather large contiguous spots. The under side of the fore-wings 

 is orange at the base, and rufous towards the hind-margin ; the 

 intermediate white space is marked with a black spot towards 

 the inner-margin. The hind-wings are brown, slightly tinged 

 with pink, paler in the middle, and reddish on the costa. The 

 discoidal spot is black and red, a short black line runs perpen- 

 dicularly from the costa, while below the middle of the wing 

 is a straight black transverse bar. The male will be white,
