When defining this remarkable genus in 1868, I httle 

 thought for how long a time the three Kaffrarian examples 

 captured by my lamented collaborator, the late Col. J. H. 

 Bovvker, would remain its only known representatives. To 

 this day, no further specimens of the type, D. immaculata, 

 Trim., are forthcoming, Staudinger's insect figured (Exot. 

 Schmett., i, pi. 94. — 1887) under that name being rightly 

 referred by Auvivillins (Rhop. ^Ethiop., p. 278.— 1899) to 

 the genus Lvptcna. Plotz's Dclonetiva marginata (Stett. 

 Ent.' Zeit., xJi, p. 204.— 1880) has been identified by 

 Aurivillius (/. c. p. 284) with the type of Mr. F. Kirby's 

 genus Aslauga, vid. A. marginalis, K. (Ann. and M, Nat. 

 Hist., (6), 6, p. 261.— 1890). No doubt the absence of 

 specimens of Ddoncura led to the misplacing of these 

 West- African butterflies ; yet my diagnosis and figure 

 (/. c. 1868) gave very clearly the singular disco-cellular 

 and radial neuration of the fore-wings and other charac- 

 teristic features, and should have sutficed to prevent the 

 addition to the geuus of species not possessing those 

 features. 



The discovery of a new species of Ddoncura (described 

 below as D. millari), in Natal, enables me to dismiss a 

 suggestion I made in 1868 {I.e., p. 82, footnote) that the 

 fore-tarsi might be (as in a very few other genera of 

 Lycasnidse) perfect in both sexes, and that of the three 

 extant examples of D. immaculata — all of which possessed 

 completely articulated and clawed fore-tarsi — the two 

 smaller might be <^ ^ and the third alone a $ . The 

 three examples of the new Natalian species comprise two 

 unc^uestionable $ $ , exhibiting not only unarticulate fore- 

 tarsi, blunt and less than half the length of the tibiie, but 

 also a conspicuous sexual badge on the submedian nervure 

 of the fore-wings, consisting of an apparent slight mem- 

 branous expansion or inflation, covereti both on upper and 

 under surfaces of the wings — but much more densely on 

 the upper surlace — with elongated pointed scales, and
