HYPOLYCAENA. By Dr. C. Aurivillius. 
oo. The transverse streaks at the end of the discal cell on the under surface are red-brown or 
yellow, bordered with white or dark. 
1. Wings beneath with a grey ground-colour and thick discal band. 
H. pachalica. 
H. aureolineata. 
2. Wings beneath with a grey ground-colour and fine, yellow transverse lines. 
H. buxtoni. 
**. Hindwing beneath with a very broad, orange-yellow discal band being reddish at the costal margin; 
that of the forewing is only feebly indicated. H. vittigera. 
B. Both wings above dull orange-red with a black marginal band. H. jacksoni. 
moyambina. H. moyambina Baker was described according to a single <$ and is unknown to me. The description 
says: ,,Both wings black; hindwing with traces of a short fine spot of blue scales in the fold and on the anal 
lobe; fringes of the forewing black, of the hindwing behind the apex white; thorax and abdomen with 
traces of some few blue scales. Both wings beneath whitish, forewing at the apex and margin covered with 
grey; a red-brown mealy spot behind the discal cell; an orange-red discal band bordered with brown, and a 
fine, interrupted submarginal line distally bordered with white; the discal cell at the end with a white trans¬ 
verse streak bordered with brown; hindwing with a scarcely noticeable transverse streak at the end of the 
discal cell and a broad, orange-red discal band bordered with dark, not undulated as far as vein ,,1“, but then 
dentate W-shaped as far as the proximal margin; a fine, undulate submarginal line and outside of it a series 
of grey spots; a black marginal line; a velvety-black spot of the anal lobe is surrounded with blue scales 
and proximally bordered with red; a large, black marginal spot curled red in the area 2 between the small tails 
being bordered with white; a white spot in 1 c.“ Expanse of wings: 28 mm. Sierra Leone. 
auricostalis. H. auricostalis Btlr. (68 b) is distinguished by the orange-yellow costal margin of the forewing. 
Butler only knew the $; H. frommi (68 c) described later on by Strand is most likely the $ of Butler’s species. 
cL (According to Strand) most closely allied with H. philippus ; a very interesting fact is that this is most 
similar to the $ of philippus, though it differs by the following marks: the upper surface of all the wings 
with a leaden reflection, but without any violet tint, the white submarginal spots in the areas 3, 4 and 5 of the 
hindwing are a little nearer at the margin and their row converges posteriorly with the margin (in philippus 
parallel), the black marginal spot in area 2 is in philippus proximally quite narrowly and indistinctly bordered 
with orange-yellow, whereas in frommi there is an orange-yellow spot which is even larger than the black mar¬ 
ginal spot; besides the black marginal spots are a little smaller and more ellipsoid and the angle formed 
by the margin at vein 3 less distinct, whilst the black anal spot which is proximally dusted greenish in philippus, 
shows here orange-yellowish dusting. Under surface darker than in philippus -$, of an ashy grey with similar 
markings, but the two transverse bands of the forewing are parallel (in philippus posteriorly divergent) and 
also anteriorly a little more remote from each other; the two bands of the hindwing are less regular than in 
philippus and at the veins more distinctly interrupted; all the bands, also those of the forewings less sharply 
marked and, like the basal spot of the hindwing devoid of red, but with orange-yellowish dusting, the two black 
marginal spots, however, are proximally bordered by one bright, orange spot each. Another characteristic 
mark is that the costal margin of the forewing is orange-yellow almost to the apex. — The according to 
Butler, is closely allied with philippus, above ashy-grey; forewing with a (particularly at the base) light golden 
ochreous-yellow costal margin; veins dark; margin smoke-coloured grey; an antemarginal, curved row of six 
whitish discal spots increasing in size; a whitish ring-spot at the anal angle; hindwing almost as in philippus, 
but at the distal, small tail witli a much larger, more light orange-yellow spot. Under surface whitish with 
dark grey markings bordered with white and huecl orange-yellow at the proximal margin. Nyassa Land. 
philippus. H. philippus F. (67 a). Wings above dark brown, in the $ with a faint bluish or violet reflection; 
forewing unmarked; hindwing with a black submarginal spot in 1 b, 1 c and 2, of which the spot in 2 is proxi¬ 
mally bordered by an orange-red spot; the black border-line is proximally bordered with white; the $ has besides 
two antemarginal transverse rows of white spots, the distal one of which consists of 3 (or 4) spots in the areas 
3 to 5 (or 6) and the proximal one of 3 or 4 spots of the areas (1 c) 2 to 4 (and 5); the distal one of these 
rows of spots is sometimes faintly indicated also in the Wings beneath grey or whitish with orange-yellow 
markings; forewing with a transverse streak at the cell-end, an almost straight discal line and a fine submarginal 
line; the hindwing with a basal dot in 7, a transverse streak at the cell-end, a somewhat irregular discal line 
angularly broken in 1 c towards the proximal margin, and a fine sub marginal line which is thickened and more 
distinct at the proximal margin in 1 b; hindwing besides with rounded, black marginal spots in 1 b and 2, 
the former being dusted blue, the latter proximally bordered with a reddish yellow; the area 1 c at the margin 
only somewhat darkened, grey and with some blue scales; the yellow discal lines are sometimes very finely 
bordered with blackish. The larva, according to Lamborn, is visited by ants of the genera Pheidole and Campo- 
notus. A common species occurring in the whole Ethiopian region.
