TERACOLUS. By Dr. C. Aurivillius. 
T. amelia is perhaps only another race of vesta, but always differs in the small, almost punctiform 
spot at the end of the forewing and in the forewing beneath being light yellowish white from the base to 
amelia, the discal band and only in the cell brighter yellow, sulphur-yellow or orange-yellow. — amelia Luc. is distinguished 
especially by having the discal band of the hindwing placed far behind the middle and almost confluent with the 
marginal band, so that the submarginal spots are very small; the cell of the forewing beneath orange-yellow; the veins 
hanningtoni. of the hindwing beneath not darkened. Senegal to Nubia. — hanningtoni Btlr. (15 e) has dark veins on the 
hindwing beneath, sulphur-yellow base to the underside of the forewing and the discal band of the hindwing 
further removed from the distal margin. British East Africa. 
protomedia. T. protomedia King (16e) is a very beautiful, bright sulphur-yellow species, which is rather isolated, 
but most nearly approaches the preceding. On the upperside of the forewing the veins, a transverse spot at 
the end of the cell, a thick discal band (which, however, terminates at vein 4) and the light-spotted marginal 
band black; the hindwing has above only a narrow, yellow-spotted marginal band, but is beneath beautifully 
ornamented with brown-yellow veins and two yellow-brown transverse bands; the ? only differs in having a 
thicker transverse spot at the end of the cell on the forewing and a dark discal spot at the costal margin of 
the hindwing. The pupa is light yellow-brown with widely projecting wing-cases and short point to the head. 
— German and British East Africa, Somaliland, Abyssinia, Nubia and westwards at least to Yola in the 
Niger region; Arabia. 
In the next 4 species the apex of the forewing above is very broadly black and contains at least in the d 2 trans¬ 
verse rows of bright, violet-red iridescent spots, which are separated by the zigzag, black discal transverse line. The proximal 
row consists in the first 3 species of 4 (—5) short spots in cellules (3) 4—6 and 8, but in zoe also of long spots in 1 b—3 
and in the apex of the cell. 
pholoe. T. pholoe Wallengr. is very similar to the following species and only differs in that the hindwing 
above has only free dark spots instead of the marginal band; the ? quite similar to the d. Damaraland. 
celimene. T. celimene Luc. (16 e, f). Both wings above with white ground-colour, at the base not or but little 
darkened; the spot at the apex of the cell on the forewing is absent or very small, punctiform; the hindwing 
above with a continuous, light-spotted, black marginal band, beneath with 3 dark brown transverse lines, of 
which the first is straight, and with some yellow longitudinal streaks in 1 b. 2 and the cell; the veins darkened 
at least at the distal margin; the cell of the forewing beneath more or less yellow; the ? has (always?) small 
yellow spots in the black apical part of the forewing above and is consequently very dissimilar to the d. 
sudanicus. South and East Africa to Abyssinia. — sudanicus Auriv. only differs in the broader marginal band of the hindwing 
above, which is 5 mm. in breadth, and the absence of the first dark transverse line on the hindwing beneath. Soudan. 
praeclarus. T. praeclarus Btlr. closely approaches the preceding species, but has the marginal band of the hindwing 
unspotted, very broad anteriorly, narrowing to a point at the anal angle and irregularly curved proximally, 
and a large black spot at the end of the cell on the forewing; the ? is quite different; above almost the whole 
apical half of the forewing is black with a transverse row of short, quadrate red spots and red marginal dots, 
beneath the base of the forewing is broadly red and behind the apex of the cell is placed a broad, bright 
red, black-spotted transverse band, which is broader at the inner margin; the basal area of the hindwing on 
both surfaces darkened, yellowish. Somaliland. 
zoe. T. zoe Grand. (l6e) has in both sexes a sharply defined blue-grey basal area on the upperside of the 
forewing; in the d this basal area immediately adjoins the black, red-spotted apical part, in the ? there is a 
white hindmarginal spot in la, lb and 2; the hindwing above white with small punctiform (d) or larger (?) 
marginal spots and in the d yellow at the costal margin, beneath white with a black discal band. This 
beautiful species only occurs on Madagascar. 
Here follow 4 small species with white ground-colour on the upper surface of both wings. The hindwing is entirely 
without markings or has above only small dark marginal spots at the extremities of the veins and beneath at most some 
not very distinct discal spots. The forewing in the ? with distinct discal spots, which are placed in a curved row. 
venosus. T. venosus Stgr. (16 d). Both wings pure white, above narrowly dusted with black-grey at the base; 
the forewing above with thin, dark marginal line, which is somewhat thickened at the extremities of the veins, 
and narrowly black veins; the ? differs in having on the forewing a curved row of dark discal spots and a 
broad marginal band. British East Africa. 
T. halimede. The forewing above at the base with a sharply defined, blue-grey patch, which covers 
the first three-quarters of the cell and the base of cellules 1 a and 1 b, at the hindmargin, at least in the d, 
halimede. with a large ochre-yellow spot, in the d without, in the ? with a black spot at the end of the cell. — halimede 
King (16 d). The light ochre-yellow hindmarginal spot on the forewing above extends at least to vein 3 and 
acaste. occurs also in the ?; hindwing above ochre-yellow at the costal margin. Arabia — acaste King (16 d, e); the light 
ochre-yellow hindmarginal spot only reaches vein 2 in the d and is entirely absent in the ?; somewhat smaller 
than the typical form. German East Africa, British East Africa, Somaliland to Nubia and from there to Senegal.
