Review of the Species. 
A. The area 2 of the forewing beneath one-coloured without a light spot or only at the margin light coloured. 
In the $ the longish, yellow spot is situate at the anal angle of the forewing above in the area 1 b. 
a. The second and third black transverse lines of the hindwing beneath are coherent. Hindwing beneath 
at the base of the areas 2, 6 and 7 orange-yellow. H. boisduvali. 
[3. The second and third transverse lines of the hindwing beneath each broken up into 4 or 5 spots. Hindwing 
beneath partly, especially in the areas 6 and 7 and on the distal side of the fifth transverse line in 1 b 
to 2 reddish-brown. H. similis. 
B. The area 2 of the forewing beneath in the middle with a large, light spot. Hindwing beneath marked almost 
the same as in similis. In the $ the longish, yellow spot is situate at the anal angle of the forewing above 
in the area 2. H. kirbyi. 
H. boisduvali Hew. (64 f) Wings above blackish with a light blue, white-spotted subapical band 
and a large, blue spot at the anal angle in 1 a to 2 of the forewing and a large, blue spot at the margin of 
the hindwing, entirely covering the areas 2 to 4 and a part of the areas 5 and 6, and separated from the margin 
by a black line. In the $ the forewing above shows a light yellow subapical band of 5 mm width and a longish. 
light yellow spot in 1 b near the anal angle. Ashanti to the Southern Congo District. 
H. similis Auriv. only deviates from boisduvali by the marks beneath mentioned in the review, 
is unknown to me. Gabun. 
The 
H. kirbyi Dew. (64 f). In the the forewing above has a blue spot in the middle of 1 b and another 
one behind the middle of 2, not or scarcely touching each other; the subapical band is white and consists 
only of small spots of the areas 5, 6, 9 and 10; the blue colouring of the hindwing above is more extensive and 
covers also the area 1 c as far as the base. In the $ the forewing above shows a very slanting, yellow subapical 
band of almost 5 mm width, nearly reaching the margin in area 4, and a long large spot in area 2; sometimes 
there also occurs a small yellow spot in lb. — Larva yellowish grey with a black head, everywhere covered 
with extremely fine and short hair; each joint has a lateral fleshy cone covered with a pencil of long grey hair; 
the first joint and the last moreover with a dorsal pencil, and the sixth joint with two very small, white brushes. 
Pupa grey, above strewn with minute black dots; sheaths of the wings marbled dark. Professor Sjostedt 
found the pupae in Cameroon on the whitish-grey, somewhat spotted bark of a tree, where they were difficult 
to discover. Cameroon to Angola. 
29. Genus: Powellana Baker. 
This genus is closely allied with the two last genera in the neuration, but it differs from all the other 
Liptenins by the veins 10 and 11 of the forewing being petioled together. The antennae scarcely reach 
the middle of the costal margin of the forewing and are slender with a slightly thickened cylindrical club. Wings 
broad with a feebly bent distal margin and a strongly bent costal margin of the hindwing. 
P. cottoni Baker { — weberi Roll.) (64 g) £. Wings above of a bright blue; the apex and margin of 
the forewing is 4 mm broad black; the costal margin of the forewing and distal margin of the hindwing is scarcely 
more than 1 mm broad black; sometimes the forewing has a white subapical spot in 5 and the hindwing one 
in 6; the dark bands beneath show through on both wings; the under surface of both wings is white with 7 or 
8 dark transverse bands or lines, the arrangement of which is best to be seen from the figure; the third and fourth 
are at their ends more or less connected with each other. In the $ the wings are broader, above brown 
with a faint blue reflection, and have a white transverse band extending from the middle of the costal margin 
of the forewing almost to the anal angle of the hindwing. Cameroon to the Congo District.
