LITHOSIA. By Dr. A. Seitz. 
phaeopera. L. phaeopera limps, is similar to sarceola, somewhat larger (expanse 30 mm), but the forewing of 
a more yellow ground-colour with a dark brown tint, the costal-marginal stripe white. Hindwing much broader 
than in sarceola, but similarly coloured. Cape Colony, to the north as far as into the Transvaal. 
sokotrensis. L. sokotrensis Hmps. (10 h) is already very near to the European lurideola, but more intensely coloured, 
hindwing at the apex brownish; forewing narrower. Sokotra. 
natara. L. natara Mr. (= vicaria Wkr., antika WJcr., sarawaka Btlr., imitans Mob., vikaria Sz.) (Vol. X, 
pi. 15 c as vicaria) resembles the preceding ones and also the following gracilipennis, but the fore wing is darker, 
the yellow costal-marginal stripe not extended to the apex, but pointedly ending in front of it. Hindwing 
more yellow though not so lemon-coloured as in the figure in Vol. X. The imago has an immense range extending 
from Tropical Africa across India, Ceylon, the Sunda Islands, and China to the palearctic Amur District, if 
this is not a mistake. The older name vicaria is better avoided, since Walker described two different species 
by this name; vicaria Wkr. of 1864 is no more to be identified and the type does not exist any more. 
gracilipen- L. gracilipennis Wallgr. (= planissima Wallgr. , elongata Rothsch.) (10 i) is larger and somewhat less 
ms - dark on the forewing, the yellow costal stripe is broader, the hindwing more ochreous, towards the costa darker; 
otherwise very similar to natara. Natal, Transvaal. 
proleuca. L. proleuca Hmps. (10 i) is only half the size of gracilipennis , otherwise similar to a small sokotrensis ; 
the yellow costal-marginal stripe is more whitish, hindwing light yellow as in some natara. Gold Coast. 
sanguicosta. L. sanguicosta Hmps. (10 i) is coloured like the preceding ones, but much larger (36 to 46 mm); 
the costal-marginal stripe is broadly yellow, in the apical part still broader, and the costal margin itself red. 
British East Africa and Mashona Land; the specimens from Lake Nyassa ( nyassana Strd.) are but slightly 
and not constantly different. 
griseola. L. griseola Hbn. (Vol. II, pi. 12 li) is said to occur in a local West African form with a brown margin 
subumbrata. of the hindwing, having been placed by Holland as subumbrata to the genus Lepista. We do not think it 
impossible that these specimens belong to natara Mr. 
similipunc- L. similipuncta Hmps. (10 k) looks like a very large griseola with a broad light yellow costal stripe, 
ia - but on each forewing it has 2 black dots as in an Oeon. quadra -$, which it also resembles in size. Mashona 
Land. 
stevcnsi. L. stevensi Holl. (10 k). Head and thorax ochreous, marked with white. Forewing very pale ochreous, 
the costal margin in the distal half thickly black. Hindwing white, in the costal region with an ochreous tint. 
Expanse 44 mm. East Africa. 
phaeocras- JL. phaeocraspis Hmps. (10 k) is similar to stevensi, smaller, the costal margin is dark yellow, not black, 
pi-s. hindwing pale yellowish. East Africa. 
simulans. L. simulaiis Mob. ( = agonchae Ploetz) is much smaller, forewing dark ochreous, in the costal area 
more golden yellow; a broad dark antemarginal nebulous band is above broad, towards the hind-margin narrower. 
(juinencola. Hindwing ochreous. Congo. — guineacola Strd. from Guinea is said to have more elongate forewings, and the 
dark antemarginal nebulous band does not taper off towards the hind-margin. 
caff ran a. L. caffrana Strd. (10 k) resembles the palearctic morosina (Vol. II, pi. 12 i) from Asia Minor, but it 
has not quite such elongate forewings, without a distinct yellow costal stripe, and purer yellow hindwings, 
Caffraria. 
suhgriscola. L. subgriseola Strd. (11 a). Smaller, otherwise similar to caffrana; it also resembles a small griseola, 
but in the forewing there is scarcely a definable costal-marginal stripe, the costal margin but little lighter than 
the leaden-grey, slightly brownish-tinted ground-colour. Spanish Guinea. 
% 
vendama. L. verulama Strd. (11 a) is quite similar to a common European sororcula (Vol. II, pi. 13 b). Forewing 
dark yellow, hindwing paler, but also the abdomen is yellow, and the hindwing beneath exhibits a dark costal- 
marginal band of about 2 mm width. Natal. 
triplaiola. L. triplaiola B.-Bak. (= malanga B.-Bak., unistrigata B.-Bak., bisticta B.-Bak.) (11a) has either 
1 or 2 small dots on the forewing, which are sometimes besides connected by a fine stripe, owing to which 
differences it has received various names. Quite similar to verulama, distinguished by an oblique dark median 
shadow which may be more or less prominent and the greatest part of which is composed of scent-scales. West 
Africa. 
lamprocras- L. lamprocraspis Hmps.' (11a) is quite yolk-coloured with a light yellow costa of the forewing. 
pis. Seychelles. 
discifera. L. discifera Hmps. (11a) is like lamprocraspis, but in the distal halves of the wings paler golden 
yellow, and the forewings show small dull cell-end spots. Natal. 
squatida. L. squalida On. (= mauritia Mob.) (11 b) is much larger, otherwise quite similar to discifera-, forewing 
somewhat broader and without the dark dot at the cell-end, hindwing paler yellow. Mauritius and Reunion.
