G. forficulata Mschlr. $ (41 a). Antennae black with light brown pectinations. Head and thorax 
ochreous mixed with brown; thoracal dorsum with smoothly appressed scales. Abdomen above rusty red 
with broad black transverse bands. Forewing above ochreous mixed with red-brown, at the base and towards 
the apex the darkest; transverse lines wavy or notched, often partly indistinct and double; discal dot black 
and distinct. Hindwing with an almost straight distal margin and thereby almost triangular, at the costal 
margin as far as vein 7 yellowish-brown, then blackish-brown with yellow veins, at the hind-margin rusty yellow; 
its fringe brownish-yellow. Both wings beneath blackish with yellow veins and margins. Anal tuft brownish- 
grey. — The $ is probably a form with a brown, smoothly scaled thoracal dorsum speckled with whitish-grey 
scales, and blackish-brown hindwings which are broadly ochreous at the base and hind-margin. Abdomen 
ochreous with distinct black transverse bands. This form, however, does not agree well with Holland's 
description of the $. Gold Coast. 
G. greyi Holl. <$. Head and thoracal dorsum whitish-grey; abdomen above orange with seven black 
transverse bands and a light yellowish anal pencil. The chest at the bases of the wings, and the metathorax 
are orange. Under surface otherwise light whitish-grey. Forewing above like the thorax whitish-grey, at the 
distal margin lighter; discal dot black; transverse lines undulating and notched, double or single. Hindwing 
with a curved distal margin, dark brown, at the base and hind-margin orange, in the centre with a shortened 
dark transverse line and without the latter with a dark nebulous band; veins light. Wings beneath grey with 
yellowish veins. Expanse of wings: 80 mm. — The 2 (39 b) is easily recognisable from the figure; it is especially 
distinguished by the patagia being at the hincl-margin clad with long and erect hairs. Ogowe. 
G. rufescens Auriv. (39 c). unknown. The as the figure shows, is particularly distinguished 
by the yellowish-brown ground-colour of the body and wings. West Africa: Asaba. 
G. punctifera Riel was described as a Taragama, but it is undoubtedly a Gastroplakaeis. $. Thorax 
violettish-reddish, collar reddish-yellow. Abdomen above bright reddish-yellow with black transverse bands 
and a yellowish-brown anal pencil. Forewing above with a brownish-yellow ground-colour which is often covered 
in the centre with violet, and a black discal dot; first transverse line double, undulated; second transverse 
line also double; the proximal line of the first and the distal line of the second transverse line are sometimes 
indistinct or absent; the submarginal line is scalariform and composed of blackish streaks or small spots. Hindwing 
above brownish-yellow, darker at the hind-margin; its distal margin slightly bent, between the veins 2 and 7 
almost straight. Wings beneath yellowish. — Thorax yellowish grey. Abdomen yellow with black transverse 
bands. Forewing yellowish ochreous, or more or less darkened by black scales, the markings as in the J. Hindwing 
reddish-yellow, at the costal margin and distal margin darkened by black scales. Expanse of wings: 52 to 55 
(db 78 to 88 ($) mm. Senegal. 
G. schultzei Auriv. <$. Light whitish-grey. Antennae black with yellow pectinations. Abdomen above 
golden yellow with 5 broad black transverse bands (at the ends of the joints 2 to 7). Anal tuft whitish-grey. 
Forewing whitish grey with a reddish hue and a black dot at the end of the discal cell ; both the transverse 
lines are double, wavy, indistinct, of a dark colour; submarginal line indistinct. Hindwing and both wings 
beneath whitish-grey without markings. Expanse of wings: 57 mm. — The $ (39 b) is much larger (78 mm) 
with distinct markings of the forewings, but without black transverse bands of the abdomen. The larva living 
on Combretaceae, chiefly Terminalia, exhibits a whitish-grey skin with a porcelain-like gloss, reticnlately 
marbled with dark; stigmata black; head grey with two black streaks. Cocoon set with the larval stings. 
Adamaua, discovered by A. Schultze. 
G. annuligera Strand. $ (41 b). Forewing reddish fawn-coloured, rather densely and uniformly strewn 
with fine light greyish scales, the total colouring more greyish-brown than in rufescens. Blackish, shadow-like, 
very indistinct transverse markings similar as in schultzei, but still less distinct and broken up into spots. The 
distinctly prominent submargmal band of schultzei is here indistinct, because it is distally not bordered with a 
lighter coloui. Hindwing above and both wings beneath uni-coloured fawn. German East Africa: Songea. 
G. parinarii Guer. was described as a Lasiocampa, but according to the description it probably belongs 
to Gastroplakaeis and might even be identical with schultzei Auriv. Head and thoracal dorsum grey. Forewing 
reddish-grey, at the distal margin lighter, above with two notched, blackish transverse bands and between 
them with a black discal dot. Hindwing light yellow, at the base somewhat reddish. Abdomen bright yellow, 
almost orange, the posterior edge of the joints broadly bordered with black. Forewing beneath greyish-brown, 
with light-yellow base and veins. Hind wing beneath, chest and ventrum light yellow. $ more unicoloured 
grey, without the reddish hue of the forewing. Hindwing darkened, only at the base somewhat yellowish. 
Abdomen red-brown, the joints at the posterior edge slightly darkened. The whole under surface dark smoky. 
Larva on a species of Parinarium. Senegal. 
G. meridionalis Auriv. The d (40 e) is easily recognisable by the figure. The $ is much larger (about 
138 mm). ,.Body very densely clothed with light greyish brown scales and hairs. Head and thorax with inter¬ 
spersed white scales which are rather densely accumulated on the patagia and in the centre of the dorsum. Legs 
deep brownish red. likewise with scattered white scales. Black transverse bands on the abdomen quite absent.
