7G ISORROPUS; PASTEOSIA; PARAONA; LAMPROSIA ; OEONISTIS; OEDALEOSIA. By Dr. A. Seitz. 
37. Genus: Isorropus Btlr. 
The only species known of this genus has bright colours, somewhat like an American Cisthene. Pro¬ 
boscis strong, the short palpi straightly porrect, antenna with a comb of rather long scales behind the centre 
of the antenna, tapering off towards the apex. Forewing with an areola; in the hindwing vein 5 is absent. 
tricolor. I. tricolor Btlr. (9 k). Body purple, marked with brown; wings orange with a broad black marginal 
band. Forewing with a broad black transverse band through the centre. Madagascar. 
38. Genus: I®ast«?osIa Hmps. 
Proboscis developed; palpi bent upwards before the face; on the anterior tibiae both the spurs are 
short. In theforewingthe 1st subcostal branch approaches the costal vein and is adjacent to it for some distance, 
but soon leaves it again, terminating separately. The 2nd subcostal branch rises far before the cell-end, sometimes 
forming an areola by anastomosing with the stalk of the 3 other subcostal branches. The lower radials rise jointly 
stalked from the lower angle of the cell. Beside 1 species from Singapore 2 Ethiopian species are known. As 
to the former cf. Vol. X, p. 199; strictly speaking, it does not belong together with the Ethiopians. 
irrorata. P. inorata Hmps., from Cape Colony, has a dark brown forewing with a black dot in the cell-end 
portion and another one in the submedian area. Hindwing light yellow, with a slight brownish tint. Expanse 
of wings: 26 mm. 
plumbea. P. piumbea Hmps. is somewhat larger; forewing dark lead-coloured, with a narrow dark yellow costal 
stripe. Hindwing orange. Likewise from Cape Colony. 
39. Genus: Paraona Mr. 
Rather closely allied to the Oeonistis , and treated upon in Vol. II, p. 63, and Vol. X, p. 197. In addition 
to the palearctic and Indian species mentioned there, two occur in the Ethiopian Region: 
cocciniceps. P. cocciiliceps Mab. (9 h), like the other species of the genus, has a darker ground-colour, but the 
head, thorax, base of abdomen and bases of wings are of a bright red. Madagascar. 
interjecia. P. interjecta Strd. (9 i) is quite different from cocciniceps-, larger (expanse 40 mm). Head, dorsum 
of thorax, and forewing silvery white, forewing with a black dot at the cell-end, and a rather indistinct greyish- 
black longitudinal stripe extending from near the base below the cell to the distal margin. Hindwing with a 
black cell-end streak. Natal. 
40. Genus : Lamprosia Hmps. 
The only species of this genus is so closely allied to the genuine Lithosia (Eilema) that it was described 
as Lithosia, but the cell has at the end two tips owing to the cross-vein being strongly proximally angular, 
and vein 5 of hindwing is present here, whereas in the genuine Lithosia it is absent. 
cborella. L. eborella Bsd. (= pygmaea Wkr.) almost looks like a very pale Liih. lurideola (Vol. II, pi. 12 i), 
but it is somewhat smaller, the forewing darkened so dull grey that the yellow costal stripe is but feebly visible. 
Hindwing yellow. Cape Colony. 
(Genus: Oeonistis Hbn.) 
To this palearctic genus to which the common European-Asiatic Oe. quadra belongs, also one South-African species 
is said to belong, described as ,, Selina airiardial a“ by Walker. Hampson lists it as alroradiella among the indeterminable 
species. The type does not exist anymore. 
41. Genus: Oe<laleosia Hmps. 
At once discernible from the preceding genera by the entirely stunted proboscis, the absence of the 
areola on the forewing, from the Lithosia by the presence of vein 5. Only Ethiopian species are known. Type: 
Oe. nigricosta Hmps. 
frontalis. Oe. frontalis Strd. (9h) is quite uni-coloured luteous, at the costa of the forewing somewhat darker, 
towards the hind-margin of the hindwing paler. Expanse 26 mm. East Africa.
