CERATRICHIA. By Dr. C. Aurivillius. 
yellow band; the white dots are in black rings, more distinct than above and occur in the areas 4 to 9 or 10. 
Hindwing above orange, at the costal margin broad black, and with a dark stripe at the proximal margin from the 
base to beyond the centre. The under surface is marked almost as in the <$$. Cameroon. Rebel describes 
and figures a $ as the $ of flava, which is very much like fasciata and seems only to differ by the yellow transverse 
band of the forewing being a little narrower and the dark costal-marginal and distal-marginal band on the 
hindwing above being still broader. Central Africa. The $ of semliJcensis figured by Joicey and Talbot is still 
darker by the entire absence of the yellow transverse band on the forewing, the forewing being thus above 
uni-coloured black with 1 to 3 white subapical spots. Semliki Valley. A fourth female form is considered by 
Heron to be the $ of wollastoni ; it closely approximates C. phocion ; forewing above uni-coloured blackish- 
brown without a yellow median transverse band, but instead of it with a small, yellowish, separate spot in 
2 and a similar spot in the posterior angle of the discal cell; besides the usual small white dots are before the 
apex, and the forewing beneath is entirely coloured and marked as above. Hindwing almost as in phocion 
beneath, but at the costal margin broadly coloured dark grey. Ruwenzori. Hereto probably also belongs 
tessmanniana Strand. ,,Very similar to C. wollastoni Heron % the upper surface differing from that of wollastoni, tessmanniar 
judging from the figure, only by the four subapical dots of the forewing being of a pure white, and the two na • 
posterior spots of the three discal spots being only indistinctly or not at all remote from each other.“ ,,On 
the hindwing beneath the dark dusting of the costal area of wollastoni is absent here, and small black marginal 
spots are present. The forewing beneath is distinguished by a yellow costal area being in the terminal half 
striated black; in the marginal area the yellow colouring extends as a narrow band landwards to vein 3, 
but the distal margin and costal margin of the wing remain black. Corresponding to the discal spots above, 
the under surface exhibits a yellow transverse band interrupted by the darker veins and posteriorly angularly 
curved. The subapical dots in the yellow area are situate in black, more or less elongate spots and are therefore 
rather distinctly prominent. The anal margin of the forewing is light greyish. Expanse of wings: 25% mm.“ 
South Cameroon. The description of the under surface agrees very well with that of fasciata, and tessmanniana 
seems to be an intermediate form between fasciata and ,,■ wollastoni-. 
C. indefernimabilis Strand. The following may be mentioned from the description: ,,Forewing dull indetermi- 
black with 4 small white punctiform spots forming an oblique row being slightly bent convex towards the margin, nabilis. 
from the centre of the anal margin to area 6, where it is 4 mm distant from the apex of the wing; the hindmost 
of these spots is the largest, triangular, somewhat yellowish, and is situate on the anterior side of vein 1 b, 
then follows a spot in area 2, appearing as a transverse band between the veins 2 and 3, whilst the spot 
between 3 and 4 is almost circular, which is also the case with the spot in area 6; before the latter spot, a 
little farther towards the base, there are two small, white spots close together, forming a transverse row 
vertically directed to the costal margin. Moreover there is a white punctiform spot in the cell, very near at 
the costal margin, but remote from the discocellular. Fringes black, but with a slight greyish reflection; the 
surface of the wing shows single greenish-yellow scales in the costal area, and in the dorsal area not far from 
the base a greenish-yellow longitudinal spot. Hindwing of a bright light yellow, but the costal area as far 
as vein 5 black, the costal margin narrow yellowish; the yellow part encloses in the basal area two blackish 
longitudinal patches which may sometimes be confluent. Forewing beneath black, the apex and a narrow 
longitudinal band at the base of the costal area are yellow, but the apical area is very scantily scaled yellow. 
Hindwing beneath yellow, but paler yellow than above, in the centre with a subtriangular black spot and 
midway between this spot and the anal margin with a subsquare black spot. Besides there is a black sublimbal 
spot in area 1 b, and in the areas 2 to 4 there may be smaller black spots anteriorly decreasing in size. 
Moreover there are two small, indistinct, black, antemedian transverse streaks in the cell, some submedian 
similar ones and a post median transverse row of such streaks between the larger spots. Body above black, 
scantily strewn with greenish-yellow scales, beneath yellow. Legs yellow with darker tarsi. Expanse of wings: 
26% mm.“ South Cameroon. In its exterior this species must be very similar to C. phocion, but as the position 
of the discal dot 7 of the forewing is not cpiite clear, I cannot decide for certain whether the species 
belongs to the Phocion-group or to the following. 
Argyrosticta-Group. 
C. argyrosticfa Pldtz (79 f). Forewing above black, in the basal part with three yellow, not transparent argyrosticta. 
longitudinal stripes, a broad one at the costal margin, a narrow one in the discal cell, and a broad one being 
sometimes spot-shaped in area 1 b, to which the base sometimes does not quite reach, and in the centre with 
7 light yellow hyaline spots almost arranged in a circle, two oblong ones of which are in the discal cell, a larger 
one in 2 and one each in 3, 4, 6, and 7; on the under surface these spots are still more distinct, encircled 
with black, and in the areas 4, 6, and 7 outside with a lustrous silvery pupil, and besides there are dots 
with silvery pupils in the areas 5, 8, 9 and 10. Hindwing on both sides almost exactly coloured and marked 
as in C. aure%-$ (79 f). The $ is unknown, to me. Cameroon to Mawambi in Central Congo.
