SOUTH-AFRICAN 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 hroad apical 
margin of fore-wing, whitish, finely hatched and clouded with dark-brown^ 
irrorated with yellow in parts, and shot faintly with violaceous. Fore- 
wing : discal spots better marked than on upper side, but never well- 
defined. Hind-iuing : 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 hody above blackish, — the head and thorax clothed with 
mixed yellow and blackish hairs, — the abdomen with the last four seg- 
ments shilling pure-iuhite^ and with an anal tuft of blackish hairs ; 
beneath white. Palpi mixed blackish and yellow above, white beneath; 
antennae black above, white-barred laterally, and whitish beneath, — the 
club with a conspicuous white bar beneath. 
$ Duller, not so hkckish as $ ; in fore-iving the tivo discal spots con- 
siderably larger, ivell-defined ; occasionally a third much smaller spot 
between second and third median nervides. Fore-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-ioing : pure-white edging with less-developed expansions. 
Under side. — Fore-wing : lower discal spots conspicuous, subcostal ones 
always more or less distinct ; yellow scaling much more developed 
hind-marginally, especially at apex. Hind-wing : much whiter 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-Avings, this Hesperid is nearly 
related to Philander, HopfF. I named it, in 1868, after the late Mr. M. J. 
M'Ken, who 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 Lantana in the Botanic Gardens. Colonel Bowker 
and Mr. A. D. Millar have both met with the species pretty frequently in the 
same vicinity.
