with long soft hairs and very sharp long stings. The latter are black, with a blue reflection, at the base yel¬ 
lowish. The hairs are whitish-grey, at the indentations longer and denser, and on the sides above the feet 
they form long hair-tufts; the lateral appendages are short and obtuse. Cocoon about 75 mm long, thick, parch- 
ment-like, yellowish-grey, and densely armed with the larval stings like a hedgehog. Cameroon. 
G. regia Auriv. (40 c). $. Forewing with traces of transverse bands and a light discal spot. Hind¬ 
wing at the anal angle broadly rounded off, at the distal margin only in the centre feebly emarginated. $ very 
large (155 mm), reddish or yellowish-brown; dorsum, legs, and ventrum violettish-brown. Forewing above 
ochreous-brown, the base and four broad transverse bands violettish-brown. Hindwing red-brown without 
markings. Both wings beneath ochreous, at the costal margin violettish-brown. Uganda. 
G. imperialis Auriv. $ (36 c). $ unknown. Upper surface with an ochreous ground-colour. Head 
and thorax suffused with a violettish brown. Fore wing with a somewhat darker ground-colour; its base and 
5 broad transverse bands (compare the figure) violettish-brown. Hindwing unicoloured without markings. 
Both wings beneath ochreous, at the distal margin and near the apex violettish-brown. The largest of the 
Gonometa- species known so far. Gold Coast. 
G. ferox Kenr. (37 a). $. Black. Head, palpi, antennae, and collar orange-yellow. Abdomen with 
fine yellow segmental margins and a yellow anal pencil. Wings black without markings. Distal margin of 
hindwing feebly emarginated. $ unknown. Madagascar. Scarcely a genuine Gonometa ; the figure shows that 
vein 8 of the forewing proceeds from the stalk of 9 and 10 (!). 
G. attersuata Kenr. (37 b). g. Head, palpi, and chest dull orange-yellow. Antennae, legs, thoracal 
dorsum, and abdomen dark chestnut-brown. Wings above dark brown; forewing with a small white discal 
dot. Hindwing with a not deeply emarginated distal margin and an acute anal angle. Madagascar. 
G. griseocincta Hmps. (37 a). The <$ differs from all the preceding species in the broadly rounded hind- 
wings. The very distinct marking and colouring is to be seen from the figure. $ unknown. North-East 
Rhodesia. 
G. christyi Em. Sharpe is quite unknown to me. Forewing: ground-colour reddish-yellow, somewhat 
lighter at the posterior margin; two darker transverse bands across the centre, the proximal one from the costal 
margin to the posterior margin straight. Hindwing: yellowish, somewhat silky, darker at- the base and hind- 
margin. Under surface: reddish-yellow, hindwing lighter, especially at the distal margin. Head, antennae, 
thorax, and abdomen reddish yellow. Expanse of wings: 86 mm. — Forewing bright reddish-yellow with 
three darker transverse lines, the two proximal ones only feebly undulated, at the posterior margin a grey 
colouring extending across the centre of the wing to the costal margin. Hindwing lighter than forevving, and 
with a slight silky gloss. Under surface as in the <3 without spots or lines. Expanse of wings: 135 mm. 
Nigeria: Jebba. 
The following species are apparently closely allied to each other and differ from the others in the sexes being 
but little different. 
G. fulvida Dist. Head and pronotum dark mouse-grey. Abdomen, antennae, underside, and legs more 
or less ochreous. Tarsi speckled with grey. Forewing dark mouse-grey, densely speckled with grey, with 
ochreous veins and two dark undulating submarginal transverse lines. Hindwing dull ochreous, semi-trans¬ 
parent-, at- the distal margin darkened. Both wings beneath dull dark ochreous and at the distal margin dark¬ 
ened. Expanse of wings: 60 mm. Transvaal. 
G. drucei B.-Bak. (40 c). Palpi, head, and antennae red-brown; thorax purple brown; abdomen 
light yellowish-brown. Forewing dark purple brown, somewhat rust-coloured on the veins; an indistinct undu¬ 
lating, slanting, light reddish line to the costal margin near the apex of the wing is accompanied by a similar 
rust-coloured submarginal line; the space between this line and the distal margin is grey; fringes dark, at the 
veins slightly interrupted by light; the posterior margin as far as vein 2 darker purple. Hindwing purple 
brownish grey, at the base and in the centre as far as vein 6 white.“ Expanse of wings: 70 mm. — ,,$. 
Quite similar to the <$. Expanse of wings: 85 mm.“ Hampson, in his treatise on lepidoptera from Rhodesia, 
supplied the figure of the $ being copied here. North-East Rhodesia. 
G. bicolor Dew. (37 b) is only known from Dewitz’ description and figure of a $. There is a re¬ 
markable consistency between Dewitz’ figure and Hampson’s figure of drucei and the differences may 
only be individually, or to be explained by the different preservation of the specimens. If, however, bicolor 
is a Gonometa, the course of vein 9 of the forewing must be wrongly reproduced. West Africa: Chinchoxo. 
G. (?) argibasis Mab. ,,Forewing red-brown, at the margins slightly darker. A black undulating 
line distally bordered with grey extends from the apex of the wing slantingly liindward and reaches the po¬ 
sterior margin near the base, at about the first third of the posterior margin. Hindwing blackish without mar¬ 
kings, at the base purely white; this colour only occupies a third of the width of the wing (of the distal mar¬ 
gin) and forms a large basal spot being distally parted by the black-edged veins. Fringes reddish. Beneath 
as above, but with distinct veins and the forewing without a line. Body blackish-brown, beneath darker. The
