MYLOTHRIS. By Dr. C. Aurivillius. 
ockracea. M. ochracea Auriv. (10 f). In the cf the wings are above and beneath ochre-yellow or dark yolk- 
colour; the forewing above with broad black marginal band continuous to vein 3 and beneath with black 
marginal spots, of which those at the extremities of veins 6—8 are confluent; the hindwing with very large 
marginal spots, touching one another. In the ? the wings are ochre-yellow; the forewing has very broad 
black streaks at the extremities of the veins and the hindwing above a broad black marginal band. Cameroons. 
flaviana. M. flaviana Smith only differs from ochracea in having the ground-colour of both wings lemon-yellow 
and the marginal spots of the hindwing much smaller; as in ockracea the ground-colour of the under surface 
is not darkened at the base. Cameroons. 
The following 11 species differ from the preceding in that at least in the cf the marginal spots on the upperside 
of the forewing are either all free or at least those at the extremities of veins 2—4. Hence the apical band, when present, 
is only very short and narrow. In the ?? the marginal spots are not at all or but little prolonged proximad. 
crocea. M. crocea Btlr. (22 a). Both wings above light saffron-yellow with small, free, rounded marginal 
spots; beneath the ground-colour is lighter, the hindwing and the apex of the forewing whitish. Ruwenzori. 
citrina. M. citrina Auriv. (12 d). Marginal spots 6—8 or 5—8 on the forewing united into an apical spot; 
. forewing above with the ground-colour lemon-yellow at the base and gold-yellow (cf) or ochre-yellow (?) at 
the costal margin; hindwing above white with sulphur-yellow (cf) or ochre-yellow (?) basal half, beneath 
almost white; forewing beneath gold-yellow, basally gradually lighter and at the distal margin almost white. 
German East Africa. 
M. erlangeri Pay. (12c). cf: both wings light sulphur-yellow, the forewing with an orange-yellow 
basal spot on both sides; of the triangular marginal spots of the forewing above only those on veins 7 and 
8 are united into a narrow apical spot, which is continued at the costal margin to the base. ?: both wings 
dirty brown-yellow, the hindwing lighter; marginal spots 5—8 on the upperside of the forewing united into 
an apical band; base of the costal margin of the forewing above blackish; all the marginal spots larger than 
in the cf. Abyssinia. 
M. agathina Cr. (10f, 14 d cf; 11a ?). In the cf both wings are pure white above with the apical 
band on the upperside of the forewing continuous to vein 6 or 5; the red-yellow basal spot on the under¬ 
side of the forewing shows through somewhat above; beneath the forewing is white and the hindwing more 
or less yellow; the apex of the forewing is also sometimes yellowish beneath; the marginal spots on the 
under surface usually small, but sometimes large and more or less joined together. The ? has the wings 
above also more or less completely suffused with reddish yellow. Occurs from the estuary of the Congo in 
the whole of South and East Africa to Abyssinia and is the commonest species of Mylothris. — Larva with 
alternate black and reddish transverse bands and sprinkled with yellow spots, with a whitish yellow longi¬ 
tudinal line at. each side; head black; lives on a species of Loranthus and wanders about like the proces¬ 
sionary larva. Pupa whitish with black markings, fastened to leaves in the usual manner of the Pierid-pupae. 
M. similis Lathy (22 a) is intermediate between agathina and rueppelli; forewing above only with a 
small orange-yellow basal spot; hindwing above at the base slightly yellowish; wings with white ground-co¬ 
lour on both surfaces; forewing beneath with large orange-red basal spot, which extends at least to vein 3; 
marginal spots and apical band as in agathina. British Central Africa. 
M. rueppelli Koch (lOf) is somewhat smaller than agathina and differs in both sexes in having a 
large, bright yellow-red basal spot on the forewing; this spot extends far beyond the middle of the cell and 
also covers the basal part of cellules la and lb; also the hindwing is above more or less sulphur-yellow (cf) 
kikuyuensis. or orange-red (?) at the base. From Cape Colony to Abyssinia. ?-ab. kikuyuensis Bart, differs in the ver¬ 
milion colour of the basal spot of the forewing and the base of the hindwing. British East Africa. 
tirikensis. M. tirikensis Neave has an expanse of only 43 mm. and differs from rueppelli in having the yellow- 
red basal spot of the forewing above and the sulphur-yellow base of the hindwing densely sprinkled with black 
scales; the apical band of the forewing is broader and continuous to vein 4. Only the ? is known. Uganda. 
kiwuensis. M. kiwuensis Griinb. ?: both wings above light ochre-yellowish; apical band on the upperside of the 
forewing as in tirikensis; both wings, especially the hindwing, beneath lighter than above: forewing at the 
base bright orange-yellow nearly to the end of the cell and in the distal half with indistinct light ochre- 
yellow longitudinal stripes between the veins; hindwing with similar longitudinal stripes in the distal part. 
At the Kiwu Lake in Central Africa. 
M. yulei Btlr. (22 a) is somewhat smaller than rueppelli and is distinguished by having the forewing 
gold-yellow at the base above and beneath; the basal spot on the upperside of the forewing is much smaller 
than in rueppelli; marginal spot 4 on the forewing above united with the apical band; marginal spots of the 
hindwing small, punctiform; hindwing beneath more or less yellowish. In the ? both wings or only the fore¬ 
wing are above light ochre-yellowish. Nyassaland and German East Africa. — ertli Stiff', only differs in the
