LITHOSIA. By Dr. A. Seitz. 
it possible that the $ of this form is the form albicans Btlr. described as a race of kingdom. — The name ,, sordida'' 1 
is not well chosen, since a very similar lepidopteron was already named Phryganopsis sordida by Felder and 
the differences of the two genera are still so uncertain that several species have changed their places in the 
two genera. Phr. sordida Fldr. is a synonym of asperatella Wlcr. and chiefly differs in the transverse stripe 
of the forewing running exactly medianly and quite straightly from the centre of the costal margin to the centre 
of the hind-margin. 
makomen- L. makomensis Strd. (10 c). Forewing dark earth-coloured brown, the transverse stripe extends 
sls • around the cell-end in a round bow. Hindwing pale yellow. Spanish Guinea. 
angulifas- L. angulifascia Strd. (10 d) is very similar to makomensis and probably the same species. End of abdo- 
cia ■ men, not only the extreme apex, yolk-coloured, the brown ground-colour of the forewing not so uniformly 
tinted, but marbled somewhat dark. Cameroon (Buea). 
tuscicorpus. L. fuscicorpus Hmps. (10 d) is somewhat smaller than the preceding ones, forewing more intensely 
tinted red-brown, hindwing pale golden yellow. The transverse stripe of the forewing is as in angulifascia, of 
which it may be merely a geographical race. Gold Coast. 
oblitterans. L. oblitterans Fldr. (= undulata Heyl.) (10 d). This very widely distributed species varies exceedingly, 
if in fact all the forms combined here belong to one species. Forewing earth-coloured brown, hindwing yellowish- 
brown; through the forewing a somewhat curved nebulous postmedian stripe not reaching to the costa. The 
typical oblitterans, which we figure here for the sake of comparison, is Indian, and Ido not know any typical 
brevipennis. specimens from Africa. Nor do I know any African specimens of the form brevipennis Pimps, (nee Wkr.) which 
is figured in Vol. X, pi. 15 a as oblitterans ; here we do not see anything at all of the transverse stripe of the 
angulifera. forewing. ■— angulifera Fldr. is the common form with a distinct transverse stripe of the forewing, pointedly 
projecting towards the margin. This species also occurs in India, but it hardly differs from the East African 
kilimanja- (kilimanjaronis Strd.), the $$ of which are somewhat greyer. -— Larva with very long hairs forming pencils 
ronis. on +} ie s i c l es G f the head; light grey; dorsum darker with a bright yellow dorsal stripe. On lichens. 
goniophora. L. goniophora Hmps. (10 d). Both wings are yolk-coloured, hindwing somewhat paler, otherwise 
similar to the preceding ones; the transverse stripe of the forewing, however, is thicker, the dent behind the 
cell-end almost rectangular, but not projecting so far towards the margin. Cape Colony. 
melasonea. L. melasonea Hmps (10 e) likewise resembles the preceding species, but the transverse stripe of the 
forewing is only obtusely broken. The dark brown fore wing shows a light yellow costal-marginal stripe. Hind¬ 
wing quite pale yellow. British East Africa. 
jractifascia. L. fractifascia Hmps. is very much smaller (expanse 20 mm); the transverse band in the forewing 
is pierced below the costa. Forewing whitish, with a yellowish-red tint and strewn with small dark scales; base 
of costal margin black; hindwing greyish-white, slightly tinted with red-brown. Cameroon. 
goniopho- L. goniophoroides Strd. (10 e). Forewing dull yellow, towards the margin lighter; the transverse 
roides. stripe is thick and feebly bent. Hindwing pale yellow. From Buea in Cameroon. 
bipartita. L. bipartita Aur. (10 e), from the Kilima Ndjaro is similar to goniophoroides, but it has broader wings 
of a purer dark yellow colour, the forewing with an ochreous tint, the transverse stripe thinner and exactly 
median. 
rufofascia- L. rufofasciata Pothsch. (10 e). Forewing light tan-coloured; the transverse band is dark red-brown and 
ta - extends obliquely from behind the centre of the costal margin to before the centre of the hind-margin. Hindwing 
paler. On the forewing beneath a conical androconium extends from the costal margin behind the centre into 
the submedian area. British East Africa. 
punctUinea- L. punctilineata Hmps. (lOf) is quite similar to rufofasciata, but the transverse stripe of the forewing 
ta - is not quite so oblique, not red-brown, thinner, near the cell-end and in the submedian area punctiformly 
thickened. British East Africa. 
punctistria- L. punctistriata Btlr. (10 f) is like the preceding ones, but the transverse stripe of the forewing runs 
differently, from the centre of the costal margin to the last third of the hind-margin, thus obliquely from above 
and inside to below and outside. Madagascar. 
curvilinea. L. curvilinea Aur. (lOe) is much smaller than punctistriata-, 6 or 7 dark punctiform shadows form 
a transverse chain bending round the cell-end across the tan-coloured forewing. Hindwing paler. Madagascar. 
catenata. L. catenata Mab. is somewhat larger, with brownish-grey forewings; the transverse chain extends 
in a similar way as in curvilinea (lOe), but it is composed of small dark streaks pierced by the veins. Hindwing 
white, at the hind-margin and distal margin with a pale red-brown tint. Madagascar. 
angulistri- L. angulistrigata Strd. (lOf). Forewing lighter or darker brown, a postmedian transverse stripe is 
gata. the centre bent like a knee, as in some specimens of L. oblitterans from which, however, this species is 
separated by the veins. Hindwing brownish, towards the base lighter. Cameroon. 
pulverosa. L. pulverosa Aur. (lOf). Wings short and very broad, forewing of <$ above covered with rough scent- 
scales. Forewing brown with an orange tint, at the apex lighter; before and behind the centre and in the distal 
area incomplete transverse streaks. Hindwing dingy white. Cameroon.
