YPTHIMA. By Dr. C. Aurivillius. 
quadri- wing, two in lc and one each in 2, 3, 5 and 6 . Cameroons. — ab. quadripunctata Strand only differs from 
punctata. tripunctata in the absence of the eye-spot in cellule 5 of the hindwing beneath. Cameroons. — ab. quinque- 
punctata P unc tata Strand has above two eye-spots in cellule 1 c and one each in 2, 3, 5 and 6 , and beneath two in 
septemocel- lc and one each in 2 — 6 . Togo; Cameroons. — ab. septemocellata Strand. Hindwing above and beneath 
lata. w ph 7 eye-spots, two in 1 c and one each in 2 — 6 . L Cameroons. 
impura. Y. impura Elw. & Edw. is beneath similar to the preceding species. Wings above brown; both wings 
with a narrow dark submarginal band and a double dark marginal line; eye-spot area of the forewing 
subelliptical, sharply defined distally; hindwing above with an eye-spot in cellule 2 and sometimes A or 2 in 
cellule 1 c, the area round them not defined, beneath with three eye-spots, a double one in 1 c and one each 
in 2 and 6 . Gaboon, Angola and East Africa. 
pup ill avis. Y. pupillaris Btlr. is allied to doleta\ smoke-brown; wings above with the marginal part lighter, 
proximally hounded by a dark line, with two fine marginal lines; forewing with a large, oval, bi-pupilled eye- 
spot; hindwing with an eye-spot in cellule 2 and a very small double one in 1 c. Wings beneath grey, densely 
striated with olive-brown, a submarginal stripe and a marginal line dark. Hindwing beneath with three eye- 
depupillala. spots, one with double pupil in 1 c, one in 2 and a larger in 6 . Central Africa. — ab. depupillata Strand. 
The eye-spots in cellules 2 and 5 on the upperside of the hindwing are large, but without white pupils. Loma. 
Y. itonia is almost the size and shape of asterope, but differs from this and from all the other allied 
African species in the hindwing having 3 — 6 eye-spots above and usually 7 beneath, placed in a nearly straight 
line. Wings above pretty uniform grey-brown with fine dark submarginal line, but without distinctly defined 
eye-spot areas. Eye-spots ringed with light yellow and with silvery white pupils. The under surface is grey 
with rather dense, uniform brown transverse striation. The number of the eye-spots varies in this species 
itonia. also and on this the unimportant aberrations here mentioned are based. — itonia Hew. has above 5 and 
beneath 7 eye-spots on the hindwing. Distributed from Sierra Leone to Angola, Manicaland, German East 
hoehneli. Africa and Abyssinia. — ab. hoehneli Holl. (29b as itonia). Hindwing above with only 3 eye-spots, otherwise 
quadriocel- similar to the type-form. East Africa. — ab. quadriocellata Strand. Hindwing above with 4 eye-spots, two 
microocel- sma ^ ones i n cellule 1 c and one each in 2 and 3, beneath with 7. German East Africa. — ab. microocellata 
lata. Strand. Hindwing above with 4, but beneath with only 6 eye-spots, the one in cellule 4 being absent. German 
pluripupil- p as t Africa, — ab. pluripupillata Strand only differs from the type-form in the eye-spot of the forewing having 
subocellata. three white pupils and being accompanied posteriorly by a small eye-spot. Central Africa. — ab. subocellata 
Strand, according to its author’s description, only differs from ab. quadriocellata in the hindwing beneath 
having one small eye-spot in cellule 2 (!). German East Africa. 
Y. albida is larger than the allied species and is at once recognizable by the blue-grey or bluish 
white, somewhat silvery ground-colour of the upper surface, with brown distal margin; the dark; transverse 
striae are sparse or some of them entirely absent and only denser towards the distal and 'costal margins. 
Beneath the ground-colour is almost completely darkened by the dense striation. The forewing has usually 
on both surfaces a large bi-pupilled eye-spot, ringed with light yellow and dark brown and the hindwing 1—3 
albida. eye-spots. — albida Btlr. Hindwing above only with one small eye-spot, in cellule 2, beneath usually with 
argentata. three ocelli in 1 c, 2 and 6 . German and British East Africa. — ab. argentata Bartel only differs in the 
hindwing above having two eye-spots, a small one in cellule 1 c and a larger in 2 . German East Africa. — 
conradsi. ab. conradsi Strand (29 c) has on the upperside of the hindwing 3 eye-spots, there being also one present in 
uniformis. cellule 3. German East Africa. — uniformis Bartel is distinguished from all the other forms by the complete 
absence of the large eye-spot on the forewing. The whole surface of the wings is silver-white; only the basal 
part of the costal margin and an extremely narrow apical part of the forewing and the inner margin of the 
occidentalis. hindwing are dusted with dark; hindwing only with a minute eye-spot in cellule 2 . Central Africa. — occi- 
dentalis Bartel is the West African race and only differs in the darker, more bluish ground-colour and the much 
larger eye-spots on the under surface of the hindwing. In the interior of the Cameroons at an elevation of 1000 m. 
Third Group. 
The antenna is extraordinarily short, scarcely reaching beyond the middle of the cell, but has a distinct, pear-shaped 
club. Forewing with a bi-pupilled eye-spot, widely removed'from the apex. Hindwing above without eye-spots. 
mashuna. Y. mashuna Trim. (29 b). Both wings above uniform dark brown; the forewing with small, reddish- 
yellow-ringed eye-spot; the hindwing without markings. Forewing beneath, as above, uniform dark brown 
without striation, at the costal margin sprinkled with some grey scales; the hindwing beneath dark grey with 
widely separated dark transverse striae and with 2—7 very small black eye-spots with silver-white pupils. 
The club of the antenna is yellowish. Mashonaland.
