TERACOLUS. By Dr. C. Aurivilllus. 
the presence in the <f also of the small black dot at the end of the cell of the forewing and the larger, 
white submarginal spot in cellule 3 of the forewing, which, however, does not agree with the specimens before 
me from Kaffirland; the winter form of the ? closely approaches the form fatma. — The form distributed 
maimuna. from Damaraland to tbe mouth of the Congo Butler calls maimuna. It is said to be distinguished chiefly 
by the dull, smoke-coloured ornamental spot and the feebly developed yellow spots of the cf; the white 
submarginal spot of cellule 3 on the forewing is always large and sometimes even proximally united with the 
ground-colour; the hindwing above with or without marginal spots. If the locality were not known, the cfcf 
appear to me to be scarcely, and the ¥¥ not distinguishable by any tenable characters from the other forms. 
A closer study of eris will without doubt show that it is not possible to find definite characters for the 
differentiation of local races.

The ornamental spot of the cf with bright blue-violet or red-violet reflection. The ?? are very variable, but have 
always on both sides of the forewing a curved row of 6—7 black submarginal spots, which on the under surface are always 
free, but above often form a broad submarginal band. This submarginal band is usually more or less completely united 
with the black marginal band and encloses light spots in cellules 2—8. Sometimes the submarginal spots are small and 
free above also,_but enclosed in a large orange-yellow apical spot (cf. 16 g). 
T. erone Anyas (17 a). The ornamental spot of the cf only consists of 3—4 short spots in cellules 
4—6, 8 and is basally so broadly margined with black that the proximal border of spot 4 is as long as or 
longer than the spot itself. The ground-colour of the upper surface in cf and ? white or sometimes in the ? 
somewhat yellowish, the under surface of the hindwing and of the apex of the forewing yellowish white or 
light yellow; the veins of the hindwing are distally finely black and the marginal spots in the cf small or 
medium-sized; in the ? very large and contiguous; both wings are above more or less broadly sprinkled with 
black-grey scales at the base. In the ¥ the black marginal band on the upperside of the forewing is larger 
than in the cf, usually reaching the hinder angle; it encloses either 3—4 white spots in cellules 4—6, 8 or 
a large orange-yellow ornamental spot with 4 black submarginal spots; at the hindmargin in cellule lb is 
placed a large black discal spot. - The winter form f. jobina Btlr. (16g) is as usual smaller and is distin¬ 
guished by having the underside of the hindwing and of the apex of the forewing reddish and more or less 
sprinkled with brown; the black markings of the upper surface are less developed than in the summer form 
and the ¥ has either a yellow-red ornamental spot or only 4 white spots (ab. albidus) in the marginal band 
of the forewing, erone is distributed on the east coast from Natal to Zanzibar and also occurs in German 
South-West Africa.

T. ione. The forms of this species are treated by Miss Sharpe as 5 different species; the so-called 
species, however, intergrade without sharp dividing-lines, so that it is often impossible to decide to which 
a specimen should be referred. All alike have the ornamental spot of the cf of moderate size (in cellule 6 
only about 7 mm.) and proximally distinctly bordered with black, consisting of 5 —6 spots, of which the last 
is usually placed in cellule 3, and the one in cellule 4 is never twice as long as broad; the veins on the 
ione. underside of the hindwing are not or only very finely black. — - ione Godt. (Lucas) (== imperator Btlr.) (1 7 b) 
is larger than erone and phlegyas ; the distal black bordering of the ornamental spot in the cf is but little 
bettoni. dusted with grey and the proximal bordering is broad or sometimes quite narrow (= f. bettoni Btlr.) Transvaal 
to Somaliland and Abyssinia, probably also Senegal. In the ¥ the basal area of the forewing above is black 
and broad, sharply defined distally and usually prolonged distad at the hindmargin, as the figure shows; as in 
the ? of erone the broad black subapical band contains either a large orange-yellow ornamental spot or 4—6 
phlegyas. light spots. — phlegyas Btlr. (= buxtoni Btlr., clifficilis E. Sharpe) (17 a) is smaller than the type-form and 
has the distal bordering of the ornamental spot in the cf densely dusted with grey, in the ? the base of the 
jalone. forewing is often, but not always (cf. pi. 17 a) less densely dusted. — jalone Btlr. is the winter form and 
differs in the more or less reddish and brown streaked under surface; in the ¥ (16g, as buxtoni) almost the 
whole apical spot of the forewing is sometimes orange-yellow. Distributed from Natal through East Africa to 
aurivillii. Abyssinia and Nubia, also occurring in German South-West Africa. Suffert gives the name ¥-ab. auriviliii to 
a female form in which the colour of the red ornamental spot shades of into pure sulphur-yellow distally and 
reaches the margin between the black marginal spots. German East Africa. 
bacchus. T. bacchus Btlr. (17 b) differs from the preceding in that all the veins on the underside of the hindwing 
in both sexes are black, but otherwise agrees almost entirely with the preceding species; as in this, the ? 
hydrophobus occurs in 2 forms, their ground-colour being sometimes white, sometimes yellow. — hi ¥-ab. hydrophobus 
Suff. the red ornamental spot is somewhat larger than usual. German and British East Africa to Equatoria. 
anomalus. — anomalus (17 b) is a very peculiar ¥-form, which., however, on account of the black veins of the under 
surface probably belongs to bacchus. — Lathy has figured a very interesting gynandromorph of this species, 
with the left side female in colour and markings, the right side male.
