underside whitish. On the forewing the spots far apart, in the basal half at the inner margin a heavy dash, 
before which often two small spots, sometimes also a larger yellow patch in the cell; the two antemedian 
blotches varying in size and shape, as in many other species, always distinctly separated, the suhapical band 
narrow, the veins crossing it more or less broadly black, the fourth spot long and projecting outwardly. Hind- 
wings red, the base black, the black marginal border variable, the abdominal margin never black, but the costal 
margin generally so as far as the base. Fringe at least at the apices of both Avings Avhite, those of the 
hindwings sometimes (particularly in $) mostly white underneath. — From the Gold-coast to the Congo and 
Uganda. 
X. aemulatrix resembles X. longipennis (1 f), but is smaller, having the forewing less projecting at the 
apex, i. e. the outer margin less oblicpie, and the hindmargin longer in proportion to the costal margin than 
h\ longipennis', in the ^ the apex blackish. Tarsi of ^ with much thinner and longer spines than in the prece¬ 
ding species, those of the front tarsi hairlike; also the genitals differ from those of the other species. On 
the foreAving invariably a narroAA’, long, yelloAV dash at the inner margin, and a small yelloAv cell-spot in the 
basal area, the antemedian spots as in longipennis, the suhapical band on the Avhole less distinctly broken up 
into spots, occasionally only the loAA^er s])ot sejAarated proximally, the preceding nervules in these cases being 
not black. HindAvings red, reddish orange or Avhitish-yelloAV. Underneath the pale markings of both AA'ings paler 
than above; the inner portion of the costal margin of the foreAving and the abdominal margin not black, in 
the red specimens the costal portion of the red area ahvays orange. From Cameroon to Uganda. — aemulatrix 
Westw. (= longipennis Mob. nec Wkr.), (1 f, as mabillei). HindAAungs red, with the black border narrow, in the 
middle at the most 3^2 mRi hi AA'idth. Described by Westavood from a specimen bearing no indication of 
the locality; the specimen preserved in the Oxford Museum has the spots on the foreAAdngs pale yellow, not 
AA’hite, as WestAA'ood says; the 5 spots composing the suhapical band are distinctly separated, the upper 3 
and the 5th small, ah. mabillei Bartel^) refers to specimens liaAong the band broader. Cameroon, Gabun, 
Congo. — campala Strand (—? doenitzi Griinb.) has the border of the hindAving much broader, measuring at 
the middle at least 5 mm; liindAAdngs red or reddish-orange: f. campala Strand, or the hindAAdngs as AA'ell 
as the spots on the foreAAdngs AAdiitish-yelloAv: = f. perpallida /orw./mv. Both forms found in FTganda and Toro. 
It is easily mistaken for X. gruenhergi which is likewise found there, but is chstinguished by the black 
hair or scales on the abdominal margin of the hindAidng, having at the same time the antemedian spots on the 
foreAAdngs less far apart and the bristles of the male tarsi not prolonged. — suda subs])- nov. resembles almost 
exactly aeniulatrix, but Avith the spots on the upperside of the head and thorax yellowish, the AAdngs even 
more rounded and the black border of the hindwings on the Avhole narrower. The tarsal spines as in aemula¬ 
trix. From IxAAddjAAd Lake, the Avestern part of KiAvu Lake; 1 G collected by R. Grauer, in the 
Tring Museum; possibly a species of its oaaoi. 
X. monslunensis. The dots on the upper sAirface of head and thorax yellowish, abdomen yelloAv, AAdth 
or AAdthout admixture of black, in the G l^^t and last but one segment more or less black, both occasio¬ 
nally comjdetely yelloAA'. Costal margin of the foreAAdng with three yellow, not white or bluish-white, dots in 
the basal area, the dash at the inner margin, if at all jAresent, short, cuneiform; tAA^o antemedian blotches, 
occasionally confluent; suhapical band as in aemulatrix and longipennis, or the first three spots nearly as long 
as the fourth and not separated by the black nervures. The spines of the foretarsi of the G prolonged, 
as in aenrulatrix, only those of the fourth segment delicate, hair-like. The species occurs in three slightly different 
forms: t. monslunensis Hmps. (2 c), from Unyoro, Uganda and the adjoining parts of British East-Africa, has 
the hindAAlngs orange, and lacks on the foreAving the yelloAV dash at the inner margin, f. signata Bart. (2 a) 
has the hindAAungs red; the forewing Avith a yelloAv dash at the inner margin. Found in the same localities 
as the former. Synonymous with signata is ruwensorica Strand, a name given by Strand erroneously to Hamp- 
son’s ab. I, AA'hich did not come from the Ruwensori Mts., but from Unyoro as Hampson himself states, f. 
neavei Hmps. (2 c) differs from f. signata in the absence of the dash at the inner margin of the forewings; Rho¬ 
desia (Neaa^e), possibly a local form. i.] 
X. nigridorsa Mah. (4 f). Body black, head and thorax dotted with Avhite; abdomen feebly mottled 
Avith yelloAv, AAdth Avhite dots at the sides and underneath, in the G l^st but one segment edged AAdth 
AAdrite, in the $ the most extreme tip yelloAv. Forewing Avith yellow spots: a dash at the inner margin (very 
small in IMabille’s figure), tAA'o sej)arate antemedian blotches and a rather narroAV suhapical band, the latter 
contiguous, only the last spot almost separated, the 4th the longest, 7 or 8 mm in length. HindAvings crim¬ 
son, AAdth very broad black border; abdominal margin in G wide, in $ very narroAV, black; costal margin 
broadly black. Underneath the spots on the foreAvings darker yelloAV than above, represented by a subbasal spot 
in the cell and a smaller one before the anal angle. Cameroon and Gabun. 
X. grandis Druce (= buchholzi Plotz, melanchiton Mab.) (4g). Body black, head and thorax dotted 
Avith Avhite, abdomen of G with a feAv feebly Avhite spots underneath and a yelloAA^ longitudinal streak at 
*) The specimen figured on PI. 1 f as mabillei is a typical aemulatrix.
