2 14 SOUTH- AFEICAX BUTTERFLIES. 



hairs ; under side of tibia3 with two or three minute spines, but no 

 terminal spurs ; tarsi long, spinose beneath ; fm^c-legs of ^ more slender, 

 with tarsus not articulated, spinose beneath, and ending in a fringe of 

 small spines. 



Abdomen of moderate length, stout in ^. 



Larva. — Elongate, not onisciform, the segments well marked, clothed 

 with down and with, long hair. (Described from drawings by Mrs. 

 Barber.) 



Pupa. — Broad, rather thick, convex above, flattened below ; back 

 of thorax, and especially back and sides of abdomen, with fascicles of 

 long hair. 



The rather long, divergent, almost horizontally projecting palpi, 

 short, abruptly-clavate antenna^, short discoidal cell, and very long first 

 subcostal and first median uervules in the fore-wings, short submedian 

 nervure of hind-wings, and stout hairless legs are characteristic features 

 of this genus, which I founded for the reception of a species discovered 

 in British Kaffraria by Mr. W. S. M. D'Urban, F.L.S. Since the 

 publication of Iiho2Mloccra Africm Austndis, two closely allied species 

 (p. limhata and D. saga, Trim.) have been found in South Africa, and 

 to them I consider must be added the little species Aslauga, Trim., 

 which in 1873 I referred to the genus Liptcna of Hewitson. On 

 investigating, also, some of the species referred by Hewitson to Liftena} 

 I have come to the conclusion that /sc«, Hewits., Acra:a, Westw., and 

 probably also lima, Libyssa, Lagyra, undidaris, and Zirccea, Hewits,, 

 should be included in D'Urhania. The species named L. Eleaza by 

 Hewitson is (to judge by the figures) rightly referred by Mr. Kir by 

 to Butler's genus Psmderesia {Trans. Ent. Soc. Lond., 1874, p. 532), 

 founded on a Gold Coast butterfly which I have not seen. 



The species mentioned are all purely African ; out of the eleven 

 held to belong to D'Urhania, three (AmaJcosa, limhata, and saga) are 

 peculiar to the Southern Sub-Region, one {Ashmga) is common to 

 South Africa and Zanzibar, and the rest are only known from Western 

 Tropical Africa. The more typical species (Atnakosa and near allies) 

 are dark-brown, with spots or patches of some shade of red, and have 

 the under side much mottled with fuscous and grey ; but the longer- 

 winged Aawa, Westw., has an ochrey-yellow under surface barred 

 marginally with black and white ; and the Lagyra group consists of 

 white almost unspotted species with blackish margins. 



The only species that I have seen in life is D. Amahosa, and that 

 only on one occasion ; the $ which I captured flew very slowly and 

 looked like a small species of Acrart. This species, however, as Mrs. 

 Barber and Colonel Bowker inform me, habitually settles on stones ; 



^ Mr. Hewitson was aware that he had brought together under this genus butterflies of 

 considerably differing characters, for he wrote {Exot. Butt., v. p. 84), " I have preferred to 

 place several heterogeneous species in the genus Liptaia, rather than to make new genera 

 to receive them."
