25. Genus: £nrosia limps. 
This chiefly Indian genus has been described in Yol. X, p. 166; it has also two Ethiopian species: 
E. lineata Hmps. (9 a). Forewing white with a dark, light-crossed transverse band through the middle; 
behind the base and before the margin an angular transverse line. From the Cape of Good Hope. 
E. fuliginea Hmps. (9 a) is very dissimilar to lineata-, forewing dark brown with a light cell-end dot. 
Hindwing black with a white basal spot. South Africa. 
26. Genus: C'hionaema H.-Schdff. (Bizone Whr.). 
In Vol. II, on pi. 12, and Vol. X, pi. 16, such a great number of species of this genus are figured that 
a glance at them gives us a good idea of the genus. We at once notice the predominance of 2 red transverse 
lines through the white forewing, being the typical marking. ■— To the description of the genus in Vol. II, p. 61, 
we have only to add that the number of forms known, which at that time had been estimated at about 80, has 
been almost doubled (140) within the last 15 years, about 100 of which are Indo-Australian and described in 
Vol. X, p. 168 to 175. -— Most of the African species are inferior to their Indian allies and, compared e. g. with 
Ch. bellissima (Vol. II, p. 12 b), they look insignificant and wretched. 
Ch. trigutta Wkr. (= atrigutta Wkr.) (9 a) is extremely similar to the Sunda-species infantula 
(Vol. X, pi. 161), but in the apex of the forewing there are mostly yet traces of red; otherwise all white 
with a black dot at the cell-end and another in the centre of the cell. — Larva according to Aurivilliiis set 
with bristly tubercles. Widely distributed in Tropical Africa. On this species the genus Isine Wkr. has been 
based. 
Ch. marshalli Hmps. (9 a) is somewhat larger, the forewing at the margin bordered with dark. In 
the costal area, in the centre and at the end of the cell there are heaps of dots being joined to chains. Also at 
the base and hind-margin as well as before the margin there are black dots. Natal. 
Ch. rhodostriata Hmps. (9 a) is marked like marshalli, but much larger; in the costal area of the forewing 
red colour is interspersed. Natal. 
Ch. rufifrons Rothsch. (9 a). Like rhodostriata, smaller, quite snow-white except the hemochrome 
frons and a costal streak as far as behind the centre of the costa. Isle of Sao Thome. 
Ch. capensis Hmps. (9 b). Across the white forewing 3 fine black, somewhat oblique lines bordered 
with red. Cape Colony. 
Ch. basisticta Hmps. (9 b). Across the forewing 2 honey-coloured, somewhat curved transverse lines; 
yellow traces at the base and apex; 3 small, feeble dark dots near the base, in the centre of the cell and 
near its end. Aburi on the Gold Coast. 
Ch. rubritermina B.-Bak. (9 b) is smaller than basisticta-, 2 red transverse lines, the distal one of which 
surrounds the cell-end dot; a small black spot at % of the costal margin. Besides a red marginal line. -— In 
rubriterminalis Strd. the two red lines do not reach to the costal margin. West Africa. 
9 
Ch. rubristriga Holl. (9 b) is very much like the preceding, but the two red transverse lines are very 
oblique and scarcely bent. Ogowe (West Africa). 
Ch. ugandana Strd. approximates rubristriga. White, forewing with a red subbasal spot; behind it 
a small black spot. Between the 2 red transverse lines 2 black dots, the distal one of which is transverse and 
situate on the cross-vein. At the apex of the wing 3 small brown marginal spots. Expanse of wings: 22% mm. 
Uganda. 
Ch. pretoriae Dist. (9 b) is twice as large as the preceding ones, but marked almost exactly like rubri¬ 
striga-, the 2 red transverse lines of the forewing are somewhat steeper. South Africa. — This form may perhaps 
be only a representative of delicata Wkr., from West Africa, which is only distinguished by lighter red transverse 
lines, the body marked with brown (rubbed off?), and some yellowish red in the base and before the apex 
of the forewing. -— delicata would then be the form described first. 
Ch. togoana Strd. (9 c) is likewise similar to pretoriae, but the red transverse lines are closer together, 
bordered with dark and close at them black dots. Bismarcksburg in Togo. 
Ch. amatura Wkr. (= hova Gn.) (9 c) is much smaller than togoana-, the 2 transverse lines are of a very 
bright hemochrome, the antemedian line rather vertical. Apical third of costa red; an antemarginal row of 
red dots. Madagascar.
