332 SOUTH-AFEICAN BUTTERFLIES. 



edging beginning below second subcostal nervule, abruptly widened 

 between second and first median nervules, and emitting a more or less 

 acute projection just below submedian nervure. Under side, — Hind- 

 wing, and (less conspicuously) narroio costal and moderately broad apical 

 margiji of forc-iving, whitish, finely hatched and clouded with dark-broivn, 

 irrorated with yellow in parts, and shot faintly with violaceous. Fore- 

 going : discal spots better marked tlian on upper side, but never well- 

 defined. Hind-iving : basal area with a round white spot between 

 subcostal nervules ; quite across middle a straight rather narrow white 

 fascia (with edges ill- defined), which crosses the extremity of discoidal 

 cell ; dark-brown with yellow scaling most developed beyond this fascia, 

 and itself succeeded by some ill-defined violaceous lunules ; about middle 

 of hind-margin a narrow whitish cloud. 



Head and body above blackish, — the head and thorax clothed with 

 mixed yellow and blackish hairs, — the aMomen with the last four seg- 

 ments shining j^wx-white, and with an anal tuft of blackish hairs ; 

 beneath white. Falpi mixed blackish and yellow above, white beneath; 

 antennm black above, white-barred laterally, and whitish beneath, — the 

 club with a conspicuous white bar beneath. 



$ Duller, not so blcvkish as $ ; in fore-wing the two disced spots con- 

 siderably larger, tvell-defined ; occasionally a third much smaller spot 

 between second and third median nervules. For e- wing : between ex- 

 tremity of cell and apex a faint trace of minute spots placed trans- 

 versely, — in one example fully developed in a curved subcostal line of 

 three. Hind-wing : pure-white edging with less-developed expansions. 

 Under side. — Fore-ioing : lower discal spots conspicuous, subcostal ones 

 always more or less distinct ; yellow scaling much more developed 

 hind-marginally, especially at apex, Hind-ioing : much ivltitcr in basal 

 area, so that median white fascia is barely separable on its inner edge. 



Abdomen not shining-white terminally, but only with thin white 

 incision rings, well-marked laterally, but almost obsolete above. 



Though smaller and with broader wings, and wanting altogether the white 

 central bar and transparent spot in the hind-wings, this Hesperid is nearly 

 related to Philander, Hopff. I named it, in 1868, after the late Mr. M. J. 

 M'Ken, Avho discovered it in Natal, and from whom I first received it. In 

 June and August 1865, and subsequently in February and March 1867, I took 

 several examples about D'Urban ; they frequented the edges of woods, flitting 

 rapidly about bushes, and when settled holding all the wings erect. I took 

 one specimen on flowers of Laniana in the Botanic (Tardens. Colonel Bowker 

 and Mr. A. D. Millar have both met with the species pretty frequently in the 

 same vicinity.
