CHARAXES. By Dr. C. Atjeiyillius. 
§§ Wings above deep black with blue markings. Hindwing in the $ without tail, in the $ with 
a small but distinct tail at vein 4. 18. Laodice Group. 
1. Jasius Group. 
A very distinct group on account of the number and variety of the markings on the under surface of both wings, in 
particular the alternate light and dark longitudinal lines at the inner margin of the hindwing in cellules la, lb (and 1 c). Both 
sexes have two tails at the distal margin of the hindwing, one at vein 4 and a longer one at vein 2; sometimes there is also 
a shorter tail at vein 3. Both wings have usually on the upper surface a light discal band, which is often sharply defined, but, 
when the ground-colour is light, occasionally shades into it without any sharp dividing line. 
Ch. jasius differs from all the other species in wanting the discal band, so that both wings are uni- 
colorous or almost unicolorous black-brown above to far beyond the middle. Forewing above with a broad 
brown-yellow marginal band, more or less divided by the black veins, preceded by a sometimes indistinct 
row of much smaller brown-yellow submarginal spots. Hindwing above with a similar brown-yellow or yellowish 
marginal band, which, however, is separated from the margin itself by a black terminal line, becomes narrower 
jasius. towards the anal angle and is there suffused with grey or grey-greenish. — In the type-form jasius L. (= jason 
L.) (vol. 1, 52 b, c) the hindwing above lias no submarginal spots or only 3 or 4 small, separate blue ones be¬ 
fore the marginal band in cellules 1 c—3 and the forewing bears distinct submarginal spots. To the south of the 
Sahara, hence in the Ethiopian Region, Lieutenant A. Schultze found at Hossere Mai’koli a specimen which 
is almost identical with the type-form, only differing in the absence of the brown-yellow submarginal spots 
of the forewing and in the hindwing having 4 or 5 slightly larger blue submarginal spots in cellules 1 c—4 (5). 
In these characters it approaches the following form and proves that that is only a geographical race of jasius. 
epi jasius. — epijasius Reiche (30 a) differs in having the marginal band on both wings broader and lighter, the submarginal 
spots of the forewing absent or only occurring near the costal margin and especially in having the blue sub¬ 
marginal spots on the upperside of the hindwing united into a broad blue transverse band, extending from 
the anal angle to vein 5, 6 or 7. — Larva beneath greenish white, above bright green with two rounded, eye¬ 
like dorsal spots (on segments 6 and 8) and a fine yellowish lateral line, beginning at the fourth segment 
and separating the darker upper from the lighter underside; the four long horns on the head reddish at the 
tip; the head with yellow lateral line. Occurs to the south of the Sahara from Senegambia to the Nile, in 
maculatus. Unyoro and Abyssinia. — ab. maculatus Suff. has like jasius seven yellow-brown submarginal spots on the 
upperside of the forewing, but otherwise quite agrees with epijasius. From the island of Konakry off the coast 
of Senegambia. 
Ch. brutus. Both wings above black or black-brown with a common white or whitish yellow discal 
band, which on the forewing is broken up into spots towards the costal margin. Marginal spots wanting; but 
the hindwing has before the distal margin 2—4 small blue spots, 2 in cellule 1 c and one each in 2 and 3. 
The under surface has a continuous white discal band; the ground-colour of the basal part is red-brown with 
the black, white-edged markings peculiar to the genus, which stand out sharply; the marginal part is brown- 
yellow next to the discal band and then ornamented with large, triangular black spots, distally bordered with 
brutus. pale grey. The hindwing also at vein 3 with a distinct, but short tail. — brutus Cr. (30 a). The discal band 
on the upper surface pure white, not or only indistinctly margined with blue, on the forewing also with a 
nutalensis. spot in cellule 7 and measuring 5 — 9 mm. in breadth in cellule 1 b. Sierra Leone to the Niger. — natalensis 
Stgr. only differs in having the discal band distinctly margined with blue and the small marginal spots somewhat 
angustus. more distinct than in the type-form. East Africa from Natal to Kilimandjaro. — angustus Rothsch. (30 a) has 
the discal band much narrower, only 2. 5—4 mm. in breadth in cellule 1 b of the forewing, and the marginal 
andara. spots of the forewing very small or entirely suppressed. Old Calabar to Angola. — In audara Ward, from Mada¬ 
gascar, the median band in the is about as broad as in the type-form, but broadly margined with blue and. 
without light spots in cellules 6 and 7 of the forewing. In the $, on the other hand, the spots in cellules 3—-7 
Junius, of the forewing are enlarged, orange-yellow, and in cellules 6 and 7 divided into two spots. — junius Obertli. 
is distinguished by having the discal band on the upper surface light yellow and in cellule 1 b of the forewing 
somalicus. 6 — -1 mm. in breadth. Abyssinia. - — somalicus Rothsch. only differs from junius in the somewhat narrower 
median band on both wings. Somaliland. 
ansorgei. Ch. ansorgei Rothsch. is nearly allied to the preceding species, but has the basal part of the forewing 
above chestnut-brown, not black; the discal band of the hindwing is bluish white. G '■ discal band of the fore¬ 
wing ochre-yellow, continuous to vein 4, then broken up into spots, one each in cellules 4 and 7 and two each 
in 5 and 6; on the proximal side of the discal band the ground-colour forms black spots in cellules 2—6; 
small light marginal dots; hindwing with orange-yelloAv submarginal spots in cellules 2—7 and 2 blue spots 
in 1 c; the tail at vein 4 somewhat shorter than that at vein 2. The $ is larger than the $ and has the me¬ 
dian band on the forewing white, only at the costal margin somewhat yellowish; the tails of the hindwing 
are longer than in the $ and the anterior longer than the posterior. A rare species, only met with as yet in 
British East Africa in Nandiland and the Kikuyu forests. 
Ch. castor has the ground-colour of the upper surface deep black, as in brutus ; the median band is
