XANTHOSPILOPTERYX. By Dr. K. Jordan.

the base, in the 9 the extremity yellow. Forewings marked with pale yellow: two large antemedian blotches, 
frequently confluescent, a subapical band dissolved in single spots, a small spot before the inner angle and fre¬ 
quently another additional one in the cell near the base. Hindwings black. Underneath the markings of the 
forewings paler than above; hindwings with a large red patch, varying much in extent, ab. batesi Bruce hatesi. 
(4 f) has on the forewings a yellow dash at the inner margin. Cameroon. 
X. hornimani differs from all other species in having on the abdomen a middle row of white dorsal 
dots. Sexes unlike, the ^ having the markings of the forewing orange, the hindwing red, the $ both white. 
Abdomen with a reddish or yellow dorsal tuft of hair at the base, in the $ the extremity tipped with 
yellow. A large triangular basal area, two large antemedian blotches, frequently united with the former, 
and a white subapical band usually followed by a white dash sitiiated between the two median nervules. 
Hindvdngs with black outer and costal margins. — hornimani Bruce {(^ = comaria Drace) (2 c, 4 f). Specimens hornimani. 
from between Sierra Leone and the Niger have the marginal border of the liindwing broad and the white 
portions of both wings ($) devoid of any yellowish tinge. Those from Cameroon, Gaboon and the Congo State 
are likewise usually clear white, but with the dash between the two median nervules as a rule distinct, the 
black space between the anal spot and the large blotch before the internal vein generally narrower than the 
black discocellular band, and the marginal band on the hindwings less broad than in the specimens from the 
Northwestern Region. — The forms from the Ituri District, Uganda (with Toro and Unyoro) and British 
East-Africa I unite under the name of melanosoma Bruce (1 e d'). cJ rather darker than Westafrican the $ melanoso- 
with a yellowish tinge, the subapical band on the fore wings somewhat broader, the dash between the median 
nervules generally larger, and the terminal band on the hindwings narrover. — In $ ab. minchini Hmjis. minchini. 
the white markings of the hindwings are so broad and confluent that of the black ground colour only a broad 
terminal band, a narrow discocellular streak and two submedian spots remain. Another, very curious aber¬ 
ration is $ ab. diffusa ab. nov. (4 g), which has the inner portion of the forewings dirty white, shading out- diffusa. 
wardly into brown, but outside of the brown nervures without any markings; only underneath the edge of the 
terminal band is faintly indicated. Hindwings white, shaded with fuscous distally, and with brown veins; under¬ 
surface more broadly white. Toro. 
c) Abdomen in both sexes ringed with black and yellow above. 
X. mozambica Mab. (lb) has the abdominal segments narrowly edged with yellow and white above, mozambica. 
The markings of the forewings orange, in the black basal area a distinct white dot before the internal vein, 
and near the costa a few bluish-white dots. Hindwings red with a large black discocellular spot; a black 
terminal band widening out considerably below the middle and marked with a yellow spot before the anal 
angle underneath. From the coast-region of German and Portuguese East-Africa. 
X. perdix Bruce (1 c). Abdomen ringed with yellow also beneath, the extremity in the black, in $ perdix. 
yellow. Forewings with two yellowish basal dots before and one below the cell, and a somewhat deeper 
yellow streak before the internal vein, but without any markings on the inner margin; a subbasal band, 
shortened both in front and behind, two occasionally confluent antemedian blotches, a generally elongate, 
oval subapical band and a round spot before the inner angle orange. Hindwings crimson, occasionally with orange 
tinge; before the anal angle a I’ed spot in the black terminal band, in the sometimes absent either above or 
on both sides: ab. indecisa Btlr. (1 c). ab. angustella Strand (= ab. 1 Hnvps.) refers to a very poorly pre- indedsa. 
served ^ specimen in the Tring Museum, from Mpuapua in German East-Africa, having the antemedian blotches angustella. 
united to a band, the three bands on the forewings narrow and approximately of the same width. — Occurs 
from Natal northward as far as German East-Africa and the Albert Nyanza. 
X. africana Btlr. {— meretrix Westw.) resembles perdix-, abdomen underneath in front with yellow, 
behind yellowish-white transverse bands, tipped with black in both sexes. Forewings in the basal area before 
the internal vein with a small yellow spot instead of a streak, hindwings without a red spot in the terminal 
border. Forewings, as in perdix, with a broad, shortened subbasal band and without any markings at the 
inner margin. Hindwing either red: = f. africana Btlr. (1 c) (= meretrix Westw.) or yellow: = f. flava africana. 
form. nov. (Id). — From Natal to Nyassa Land. flava. 
X. flavisignata Hmps. Abdomen, as in perdix, ringed with yellow also beneath; the subbasal flavisignata. 
on the forewing narrow, broken up into spots, preceded before the internal vein by a small yellow oblique 
streak; median blotches as in perdix-, subapical band narrow, the 4th spot projecting outwardly, the 5th 
short and nearly isolated. Hindwings salmon red with narrow black terminal border. — Lusinga, on the east 
shore of Victoria Nyanza; 2 in the British Museum.
