five spots strongly incurved, so that the last spot is 

 rather nearer base than the first one ; a faint trace of a 

 sixth spot just below 1st median nervule ; a row of three 

 small and very indistinct spots of the same colour a little 

 beyond and parallel with upper part of discal row ; at 

 extremity of cliscoidal cell a scarcely visible ochreous- 

 yellow spot, preceded by a similar not quite so indistinct 

 spot in cell. Hind wing : Discal row of five spots less 

 distinct than in fore wing, not curved, but rather 

 irregular; the 1st and 2nd spots sublinear and confluent, 

 the last minute (below 1st median nervule). Cilia of 

 both wings dark brown, interrupted with white between 

 nervules. Under side : Dark brown, variegated with 

 whitish. Fore wing : 1st spot of discal row small, 

 white, the remainder larger than on upper side and of a 

 paler yellow; in discoidal cell a longitudinal whitish 

 streak from base and a terminal whitish spot ; between 

 extremity of cell and discal spots a transverse row of 

 three short whitish rays ; spots beyond discal row dis- 

 tinct, white ; three or four small white marks between 

 nervules on costal edge beyond middle. Hind wing : 

 A conspicuous, irregular, white, discal stripe, well de- 

 fined internally but not externally, and very sharply 

 angulated on radial nervure ; before discal stripe the 

 following whitish marks, viz., one on costa at base, one 

 in discoidal cell at base, and another just before extremity 

 of cell ; and an interrupted transverse row of very in- 

 distinct spots before middle ; between discal stripe and 

 hind margin a row of thin internervular lunules. 



From D. amakosa, Trim., this species is at once dis- 

 tinguished by (1) the conspicuous sharply-angulated 

 white stripe on the under side of the hind wing. Other 

 differences are (2) the want of whitish irroration gene- 

 rally on the under side ; and on the upper side, (3) the 

 more sharply incurved discal row of spots in the fore 

 wing, and (4) the not incurved and more irregular row in 

 the hind wing. A distinction is also perceptible in the 

 form of the wings, as (5) they — especially the fore wings 

 — have a much less curved costa and more produced 

 apical region. 



Only a single specimen of this interesting D'Urbania 

 has come under my notice. It was taken by Mr. L. 

 Peringuey, of Cape Town, in January, 1882; on the 

 Ilex Eiver Mountain, in the Worcester district of the
