Genus Zeritis, Wesiw, 

 Zeritis orear, Trim. (Plate VI, figs. 19, lO^/.) 



Zeritis orcas, Trim., Trans. Ent. Soc. Lond., 1891, 



p. 176. 

 Chrysoritis oreas, Butl., Proc. Zool. Soc. Loud., 1897, 



p. 849. 



This extremely distinct species of Zeritis — as I have 

 pointed out {I. c.) — comes closer to Z. chrysantas, Trim., 

 than to any other congener, but its under-side maikiug is 

 quite unique. 



I have given (/. c.) Mr. J. M. Hutchinson's interesting 

 account of his discovery of Z. orcas in the year 1890, at an 

 estimated elevation of about 7,000 ft. in the Drakensberg 

 Mountains, Natal, and Mr. Butler has published (/. c.) Mr. 

 G. A. K. Marshall's notes of his subsequent visit with Mr. 

 Hutchinson to the same locality, in September 1890, 

 identifying it as the " summit of Niginya, 6,500 ft., some 

 10 miles from Ulundi." On this visit over fifty specimens 

 were taken, but only in a limited area of two or tliree 

 acres. No other locality for this butterfly is known. The 

 $ here figured is one of those captured by Mr. Marshall 

 on the occasion mentioned, and the ^ was taken by Mr. 

 Hutchinson, and presented to me by Mr. C. N. Barker in 

 1898. 



Genus Arrugia, Wallengren. 



Arrugia protumnus (Linn.). (Plate VI, figs. 20, 

 20rt, 20h.) 



Pcqjilio protumnus, Linn., Mus. Lud, Ulr. Reg., p. 840, n. 

 158 (1764), and Syst. Nat. (Ed. 12), p. 794, n. 258 

 (1767). 



I give figures of the typical (Cape Town) form of this 

 remarkable South-African butterfly, because those hitherto 

 published — Cramer's, Herbst's, Donovan's, and Staudinger's 

 ■ — are extremely poor, and fail to render its characteristic 

 features with any approach to accuracy. 



As described by me in S.-Afr, Butt., ii, p. 228 (1887), 

 the typical form of iirotumnus is the dullest in colouring, 

 and appears to belong only to the extreme S.W. of Cape
