in species of Phasis, but as much as I knoiv, they do not occur together there. Margin of the wings and fringes 
entirely margined. Palpi long, with appressecl scales and without bristles. Anterior tibiae unarmed. As to the 
marking, the discal spots are only proximally and distally (not all around) bordered with black, and the discal 
spots of the areas 1 b to 4 on the forewing are in an almost straight line. Abdomen of the $ at the apex with a 
dense ball of scales. Only 1 species is known. 
C. leroma Wallengr. (70 i). Both wings above monotonously light blackish-grey without markings 
(the spots beneath show somewhat through); fringes distally whitish; anal lobe scaled blackish. Under surface 
lighter grey with whitish spots on the forewing and indistinct or white ones on the hindwing; forewing with 
a broad black longitudinal streak at the base of area 1 b, a silvery dot at the base and a larger one posteriorly 
bordered with black in the centre of the cell, a transverse spot at the cell-end and 8 or 9 discal spots, of which 
those of the areas l b to 5 are only filled up with whitish, those of the areas 6, 8 to 11 more lustrous silvery 
directly on the outside of the discal spots a row of indistinct, silvery postdiscal streaks; hindwing beneath 
with basal and discal spots, postdiscal streaks and marginal spots all of which are generally very indistinct, 
but sometimes white and distinctly prominent, albomaculata form. nov.\ anal region yellowish, anal lobe black; 
the small tail is black with a white apex. The species was described by Wallengren according to specimens 
from the Collection of J. A. Wahlberg probably originating from Natal or Transvaal, and it has later on been 
met with in Cape Colony, in the Damara and Mashuna Land and even in German East Africa near Kigonsera. 
22. Genus: Erikssouia Trim. 
Eyes bare. Palpi long, porrect, below densely clad with hair-like scales. Antennae of moderate length, 
towards the apex only gradually thickened with a distinctly defined club. Forewing with 12 veins; vein 7 into 
the margin; vein 6 for some distance forked with 7. Hindwing at the anal angle distinctly lobate or angular 
without a small tail. Anterior tibiae in the G at the apex armed with a strong spine. Middle and posterior 
tibiae with very short terminal spurs. 
The species of this genus, by the colour and markings, recall certain forms of the Lipteninae, but 
they are actually closely allied to the genus Phasis and differ from all the Lipteninae by the hindwing 
being distinctly extended at the anal angle. 
Both species closely agree in the number and arrangement of the black spots beneath. The forewing 
has two successive dots in the discal cell, a transverse spot at the cell-end, generally a basal dot in 1 b, and 5 
or 6 discal spots of which those of the areas 1 b to 3 are situate nearer at the base than the others, the 
discal spots in 4 to 6 are situate in an almost straight transverse line, the spot in 1 b being sometimes absent; 
2 to 3 mm distant from the margin extends a coherent dark submarginal line or a row of submarginal 
streaks. Hindwing beneath with one basal dot in 1 b, two in 1 c, two in the cell, and one in 7, a transverse 
spot at the cell-end and 7 or 8 discal dots of which that in area 7 is larger and situate right before the 
spot at the cell-end; behind the discal spots there extends, like on the forewing, a dark, more or less bent 
submarginal line which borders proximally on the marginal band. 
Review of the Species. 
A. Marginal band above narrow, only 1 mm broad. On the under surface the veins are at the margin not or 
but finely black, the ground-colour there not divided into spots. E. acraeina. 
B. Marginal band above broad, on the forewing at least 2 mm broad. On the under surface the veins are 
between the margin and the submarginal line broad black and divide the ground-colour into 6 or 7 light 
marginal spots. E. cooksoni. 
E. acraeina Trim. (11 a). Wings above orange-yellow with a black marginal band of about 1 mm width 
and with markings faintly showing through from beneath; forewing with a black costal-marginal band beginning 
at the centre of the cell and reaching to the apex, but being before the apex deeply indented by the ground¬ 
colour in area 6; sometimes there are also above some of the discal spots distinctly visible; hindwing above 
unmarked or with a distinct black submarginal line. Beneath lighter or darker orange-yellow with the above- 
mentioned markings, the basal and discal spots small or moderately large. Discovered in the Ovambo Land 
by the Swedish explorer Axel W. Eriksson. 
E. cooksoni Elam. Druce (74 a) is larger and darker, more reddish than acraeina, particularly beneath 
where the hindwing is covered with red at the base and between the discal spots and the submarginal line; 
basal dots large; the submarginal line, the black marginal line, and the broad black ends of the veins
