species, being already as early as 1875 used by Butler for a species of this genus, but the name ochracea 
may be retained to designate the individual form with yellow abdomen. — niepelti Oherth. I only known niepelti. 
from the description and figure. Abdomen in both sexes yellow (?), the black costal margin of the forewing 
broader at the base than in the preceding forms, with orange instead of white spots ; the lower black ante- 
median spot on the same wing is broadly confluent with the black border and united by a fine streak below 
the cell with the black discal band, so that there appears an isolated orange median spot; fringes of the fore¬ 
wings, as in f. zeodita, largely black, only at the apex and anal angle black. — M’Pala on the westshore of 
Lake Tanganyika. 
X. karschi Holl. is likewise a most variable species. Abdomen black or yellow, frequently with an ad¬ 
mixture of yellow, resp. black, and often spotted with white or yellowish beneath, in the $ the extreme end 
distinctly orange, occasionally with only a few orange scales. Forewings with two yellow transverse bands, 
the subapical band at least by one half narrower than the black apical area, reaching the upper median vein, 
indented inwardly at the third radial nervule; below the band a narrow spot forming an acute angle with the 
last spot of the band; the median band consists of two large patches generally separated by the fine black 
median vein, the second one of which projects basad either in front and behind or only anteriorly; before the 
anal angle a roundish spot, in the basal area a small spot within the cell, two further ones before the inter¬ 
nal vein, and a dash at the inner margin; all these are yellow, with a few additional small spots of bluish; 
but those yelloAv spots may frequently either in part or entirely be absent. Hindwings red or yellow, the basal 
area always more or less black, also the black border varying in width, the abdominal margin occasionally only 
with black hair, but in the majority of cases broadly black. Known to exist from Cameroon to the Congo 
Region. According to the colour we distinguish: f. egregia Wicligr. Hindwings more or less red; only known 
to me from Cameroon, f. tris/riata Bart. (= tessmani Strand) has the hindwings orange, generally suffused iris^riata. .e 
with red beneath, f. karschi (2 c), Hindwings pale yellow, abdomen black? f. hollandi worn. wov. (= kirbyi Aam-Zit 
Holl. nec Cari)ent.)^ Abdomen yellow both above and beneath. According to the extent of the spots on the hoUcmdi. 
forewings and of the black colouring of the hindwings one might establish in addition to the above a great 
number of individual groups, to which may be probably referred A", ahacata Karsch and lomata Karsch, both 
described from a badly preserved specimen the sex of which is not given; from Cameroon, not German South¬ 
west Africa, as mentioned in Strand's Catalogue of the Agaristidae. However, it is advisable to await a 
closer examination of the two specimens in question; should my sup])osition prove to be correct, the name 
of the species must be ahacata. 
X. gruenbergi Wichgr. takes the place of karschi in LTganda and the adjoining parts of British East 
Africa. The spots on the forewings are yellowish-white, beneath almost clear white, whereas in karschi they 
are beneath darker than above. Marginal border of the forewings very broad in front, the black basal area 
above not any broader than the border at the middle, the abdominal margin clothed with black hair 
(S) or having only the outer edge black. iVbdomen black, or (in $) greyish yellow beneath, the latter with 
the tip occasionally orange. Hindwing yellowish-white (f. gruenbergi Wichgr.) (2 b as paucicolor) or red gruenbergi. 
(atribasalis Hmps.). The subapical band of the forewing generally much narrower than in karschi, and more atrihasalis. 
distinctly separated in spots, resembling A. longipennis (1 f). The basal area occasionally with a distinct 
cell-spot, two spots before the internal vein and a dash at the inner margin. The two specimens mentio¬ 
ned by Hampson from Uganda and Unyoro as aberrations of ,,cirbyi\ and named from his discriptions by /1 
Strand ab. campala and ah. alice, do not belong here. 
X. abacata Karsch. (2 a). Collar and tegulae according to Karsch with white, accorchng to Bartel ahacata. 
with yellow spots; basal area of the forewings without any yellow spots, the lower antemedian spot tapering 
posteriorly; the spots on the forewings paler beneath than above (in our specimens of karschi the reverse 
is the case). Hindwings orange with broadly blackish basal area above and equally broad black border; abdomen 
clothed with dull yellow hair, legs black, foretibiae covered with ochreous-yellow hair. A much-damaged spe¬ 
cimen from Cameroon in the Berlin Museum. 
X. lomata Karsch (5 a) resembles the preceding, but with the forewings shorter (possibly $?). Abdo- lomata. 
men covered with plain dull yellow hair; on the forewing the antemedian discal spot projecting basad anteriorly, 
the second spot tapering in front. Hindwings ochre-yellow, at the innermost base blackish, the black border 
very broad, the fringe at the apex yellow both above and beneath. One much damaged specimen in the Berlin 
Museum. As above said, it is possible that neither ahacata nor lomata. are specifically different from 
karschi; to decide this, a comparison with a series of freshly captured specimens from Cameroon would be 
desirable. 
X. flavipennis Bartel (2 a) has the yellow markings of the basal area of the forewings very broad and flavipennis. 
the posterior yellow median spot projecting towards the base at the cell. The hindwings have only a trace of 
black at the base, otherwise orange with feeble suffusion of red or orange. Congo Region. 
X. longipennis Wkr. (= alice Strand, ? doenitzi Griinh.) (1 f). Head and thorax spotted with white; longipennis. 
abdomen dirty yellow, that of the ^ tipped with black, the last but one segment of the and on the under¬ 
side also the two or three preceding segments in both sexes edged with white, in the C occasionally the entire
