CHARAXES. By Dr. C. Atjrivillitts. 
The two following species differ very considerably from the preceding and are distinguished by having the under¬ 
side of the forewing white or silvery at the costal margin to the end of the cell and also by the hindwing beneath having 
a nearly straight silvery median band, only 2—3 mm. in breadth. The transverse markings of the under surface are reddish, 
as in the other species of this group, and only black in cellule 1 b of the forewing. The base of both wings above more or 
less broadly red-yellow or red-brown. The females with light yellow median band. The hindwing with two well developed tails. 
Ch. boueti is distinguished by a material reduction of the black markings on the upper surface. In 
the $ the basal part of the forewing above is only separated by a row of free black spots from the broad, conco- 
lorous median band and the marginal spots also only by a nearly straight row of thick, lunulate, black spots 
from the median band. In cellules 3—7 of the forewing the median band is divided into two by black spots. 
boueti — In boueti Feisth. the spots which divide the median band in cellules 3—7 are united into a band; the trans¬ 
verse streaks in the basal part of cellule 2 on the underside of the forewing are black; the $ is unknown. 
lasti. In Senegambia and the interior of Sierra Leone. — lasti Smith ($ 31 a, as boueti). $: the black spots on the 
upperside of the forewing which divide the median band are free or nearly so; the hindwing above is almost 
unicolorous red-yellow, only before the distal margin with a row of black submarginal spots. The $ has a whi¬ 
tish yellow median band, which on the forewing is already divided into two branches from cellule 2, the proxi¬ 
mal one composed of very irregular spots; the distal part of the forewing is black with small red-yellow marginal 
spots; the basal part of both wings yellow-brown; the hindwing with a broad black submarginal band before 
redans, the red-yellow distal margin. Manicaland to Mombasa in British East Africa. — In rectans RothscJi. <Sc Jord. 
(S) the marginal spots of the throwing are larger and the marginal band of the hindwing narrower than in the 
type-form. Forewing beneath with a silvery transverse band beyond the middle. Abyssinia. 
cynthia. Ch. Cynthia Btlr. (31 a $). The $ is above confusingly like that of lucretius (30 d), the only particular 
difference being that the red-yellow marginal spots on the forewing are smaller and the red-yellow marginal 
band of the hindwing broader; beneath, however, it agrees almost completely with boueti and hence is very 
different from lucretius. The $ is on both surfaces similar to that of boueti, differing above in the darker black- 
brown basal part of both wings, in the brighter yellow median band, which is red-yellow in cellules 3—7 of the 
forewing, and the larger marginal spots. Sierra Leone to Angola and LTnyoro. 
5. Lucretius Group. 
The cell of the forewing beneath with three undivided black, white-margined or entirely white transverse streaks. 
The wings above black with red-yellow markings, in the last species milk-white in the basal part, or in the $ blackish with 
common white median band and the base of the costal margin of the forewing red-brown. 
lucretius. Ch. lucretius Cr. $ (30 d). Wings above black with slight bluish reflection; forewing rust-brown in the 
cell and at the costal margin, beyond the middle with a nearly straight row of 8 large red-yellow spots and 
with similar but smaller marginal spots; hindwing beyond the middle with red-yellow, posteriorly narrower 
discal band and with broad red-yellow marginal band; the under surface red-brown with black transverse 
streaks in the basal part. In the $ both wings above are smoke-brown with common whitish discal 
band, placed as in the £ but much narrower; the marginal spots of the forewing very small or in¬ 
distinct ; the marginal band of the hindwing much narrower than in the $ and whitish with orange-yellow 
tinge; the base of the costal margin of the forewing only very narrowly red-brown; the under surface lighter 
than in the <$ and with whitish discal band, which is broader than above. In the West African forest-region 
from Sierra Leone to Angola and Uganda, widely distributed and very common. 
odysseus. Ch. Odysseus Stgr. (30 d). Of this rare species only the 9 is known. It somewhat recalls the 9 of 
lucretius but is smaller, has short, obtuse tails to the hindwing and instead of the light marginal band on the 
hindwing a row of 6 white submarginal spots in cellules 2—7. The wings are dark umber-brown above, somewhat 
lighter at the base of the forewing, and have beyond the middle a narrow whitish discal band, more or less 
broken up into spots, two being placed in cellule 5 and two in cellule 6 of the hindwing; in the basal part 
of cellules 3—6 on the forewing there are also small light spots; forewing at the distal margin with light spots 
in cellules lb—3. One of the many species peculiar to the island of St. Thome. 
lactetinctus. Ch. lactetinctus Karsch (30 d). Both wings above broadly suffused with milk-white at the base; the 
forewing then black with orange distal band, cleft at the costal margin, but at the hindmargin indistinct in 
cellules la and lb and with orange marginal spots; the distal half of the hindwing black with narrow orange 
marginal band, preceded by blue spots; thorax and abdomen above milk-white. Both Avings beneath dark 
violet-brown; the cell of the forewing with two transverse streaks, the first and second black and Avhite ringed, 
but the third entirely white. A rare species, only observed in the Togo hinterland and Adamaua. 
6. Tiridafes Group. 
The forewing beneath in cellule lit near the hinder angle with two large, more or less united, black spots, proxi- 
mally bounded by a thick, yellow lunule. The cell of the forewing beneath with three black, white-margined transverse spots, 
the second of which is occasionally broken up into two spots of unequal size. The wings above black with blue markings 
and in the females with white transverse band on the forewing; the ground-colour in the $ sometimes olive-grey. The veins 
are brown and the hindwing beneath has transverse markings at the costal margin in cellule 8. The hindwing in both 
sexes Avith tAvo tails, which, however, are sometimes very short, hardly more than teeth.
