hrunnea. C. bruiinea B.-BaJc. is evidently closely allied with the two preceding, but known to me only from 
the description. ,,Both wings monotonously dark umber-brown, without markings. Under surface: hindwing 
white, at the margin tinted olive-brown; costal margin as far as vein 8 brown; a very large brown spot covers 
the whole margin, and is proximally bent, whereby the white part is distally emarginated in the shape of a 
crescent; the brown marginal band is indented at vein 4 and ends at vein 2; in the white area there is a dark 
spot at vein 8 with two slanting dots before them and two small spots below vein 2. Expanse of wings:

phocion. C. phocion F. (79 g). With respect to the sexes and their variability and to the following species 
there prevails great confusion which can only be reduced to order by breeding and observations in nature. 
According to Holland (1920), argyrosticta Plotz would be the $ of phocion. Rebel, however, probably by 
rights (see below) considers argyrosticta to be a distinct species. Another difficulty is that some $$ which were 
described as female forms of flava and its races, can hardly be distinguished from typical phocion. I do not 
dare to decide whether the difference between phocion and flava having been stated in the review can stand 
the test. Joicey and Talbot who had a very great material before them, report (1921) that they were unable 
to decide which $$ belonged to phocion and which to flava. —- $ and $: forewing above blackish-brown uni¬ 
coloured without white dots (<J) or with some small white dots in 4 to 8, rarely also with one similar dot 
each in 2, 3, and the discal cell (d\ $); beneath the dots are generally more complete, and the dot in the 
costal angle of the discal cell is almost invariably distinct, at the costal margin and in the apical part there 
occurs sometimes brownish-yellow dusting. Hindwing above lighter or darker yellow, at the base and at the 
costal margin as far as vein 5 or 6 blackish-brown, at the proximal margin rarely longer than to the centre 
darkened; no dots or spots at all; the under surface is quite light yellow with small, silvery white dots, which 
are more or less bordered by brown scales and which are rarely quite absent (a separate form ?) and sometimes

at the apex of the wing sometimes brown. Sierra Leone to the Congo District. 
C. flava. The of this species are at once recognized by the bright yellow, spotless basal half of 
the forewing above. The extent of this yellow colour and in connection with it the width of the black marginal 
band vary, however, a great deal. The hindwing is in all the races above yellow without spots or only with 
small dark marginal dots at the ends of the veins, and with a narrow dark apical spot which is rarely extended

the base and the blackish-brown marginal band entirely reaches the costal margin and also covers the basal 
half of the areas 4 to 6; the marginal band is thereby only about 3 mm broad in these areas, and only in 
the areas 7 to 9 it is somewhat extended towards the base. At the base there is only a short black streak

very closely allied to flava and only differs by the dark marginal band on the fore wing above being on the

band extending from the base to the marginal band and reaching to the discal cell. The marginal band is still 
broader than in ivollastoni and seems also to cover the base of area 3; the base is also more broadly covered
