MYLOTHRIS. By Dr. C. Aurivillius. 
Pull. 7. VII. 1.910. Agathina Group. 
The marginal spots of the hindwing entirely free and rounded, at least on the under surface, rarely very small or 
absent. The forewing below only with isolated or nearly isolated marginal spots. The numerous species of this group are 
very nearly allied and form an almost continuous series of forms. 
M. nubila Moschl. (lib). Wings above and beneath with white (cf) or grey (?) ground-colour; fore- nubila. 
wing in the cd above dusted with blue-grey at the base and along the costal margin; the dark apical band 
4 mm. in breadth and only continuous to vein 5; in the ? there are only free marginal spots on both sides. 
Cameroons and Gaboon. 
M. sjoestedti Auriv. (11 a) has like the preceding species a large blue-grey basal spot on the forewing sjoestedti. 
above and white ground-colour, but differs in having the black apical band on the upperside of the forewing 
9—10 mm. in breadth and continuous to vein 2 or 3 and the basal part of the forewing beneath yellow; 
the ? is unknown. Cameroons. 
M. spica Moschl. (lOd) cd. Both wings with white ground-colour and beneath with isolated, rounded spica. 
marginal spots; forewing above without basal spot but with a black apical band of about 6 mm. in breadth, 
which is continuous to vein 3, beneath with yellow basal spot, which does not reach the middle of the cell. 
The ? differs in having the forewing ochre-yellow above and only whitish at the hindmargin, with elongate, 
streak-like marginal spots, which are usually entirely free proximally and only rarely connected by a dark 
curved line as in the figure. Ashantee to the Congo and eastwards to Victoria Nyanza. In ?-ab. caspi Stiff, caspi. 
the spots between the black marginal spots of the forewing are grey instead of yellow as in the type-form. 
Togo and Cameroons. — schumanni Stiff, only differs in that the marginal spots on the hindwing above in schumanni. 
the cd are small and punctiform and that the ? has on the upperside of the forewing a black marginal band 
strewed with yellow scales, which is continuous to vein 2. Island of Conakry off the coast of Sierra Leone. 
M. poppea differs from spica in the cd in having an orange-yellow basal spot on the forewing above 
and in the ? in the white ground-colour of both wings. — In poppea Cr. (lOe) the black marginal band of poppea. 
the forewing above in the cd is only continuous to vein 2 and the ground-colour between the elongated 
marginal spots on the upperside of the forewing in the ? is white or whitish. Sierra Leone, Togo. - hilara hilara. 
Karsch (IOe) has the marginal band of the forewing above in the cd continuous at most to vein 3 and grey 
ground-colour between the black marginal spots on the forewing above in the ?. Cameroons to the Congo 
and Uganda. ?-ab. continua Auriv. Ground-colour of both wings white; the forewing above in place of the continua. 
long marginal spots with a broad black marginal band continuous to vein 2 and proximally emarginate. 
Ruwenzori. ?-ab. dubia Auriv. only differs from continua in having the ground-colour of both wings yellowish dubia. 
white above and yellowish beneath and the basal spot on the forewing above more distinct; French Congo. 
M. asphodelus Btlr. (10 e) only differs from spica in that, the forewing of the cd above has a sulphur- asphodelus. 
yellow basal spot and the dark marginal streaks on the upperside of the forewing in the ? (beethoveni Stiff.) 
are broader and shorter. Old Calabar to Angola. 
M. primulina Btlr. differs from asphodelus in that the yellow basal area of the forewing is extended primulina. 
to the apex of the cell, covers the basal third of cellules la and lb and at the costal margin almost reaches 
the apical band; the yellow colour is darker at the base, distally sulphur-yellow; beneath the forewing has 
yellow longitudinal streaks before the apex in cellules 3—7. Lagos. 
M. dimidiata Auriv. (12 b) is nearly allied to the preceding, but easy to distinguish in that the sulphur- dimidiala. 
yellow colour on the upper surface of the forewing does not extend behind the cell into cellule lb and is 
not darker at the base, but on the other hand it completely covers cellules 3 and 4 and even a part of cel¬ 
lule 2, and that cellules 4—7 on the underside of the forewing are not traversed by yellow longitudinal 
streaks; on the under surface of the forewing the yellow colour has the same extent as above, but is gold- 
yellow at the base. Sierra Leone. 
M. basalis Auriv., like the preceding species, has the broad black subapical band on the upperside of basalis. 
the forewing continuous at least to the middle of cellule 2; the whole cell and the basal part of cellules la, 
lb, 2 and 3 are light sulphur-yellow; the costal margin, the basal part of cellules 4—8 and the distal part 
of cellules la—3 on the contrary are pure white; the sulphur-yellow colour has the same extent beneath and 
is scarcely darkened at the base; hindwing white on both surfaces, at the base sulphur-yellow and with 
rounded, free, black marginal spots. Congo region. 
M. sulphurea Auriv. (10 f ). Forewing above bright sulphur-yellow, at the base gold-yellow with broad sulphurea. 
black subapical band, continuous to vein 3 or 2; hindwing white on both sides, light sulphur-yellow at the 
base, with the usual black marginal spots; forewing beneath orange-yellow from the base to beyond the apex 
of the cell, otherwise sulphur-yellow and with free black marginal spots. Cameroons.
