Forewing above densely clothed with greyish-brown and lustrous white scales, two prediscal and two postdiscal. 
narrow brown bands irregularly notched and undulated as in the but very indistinct. The black discocellular 
spot is very sharp, circular, surrounded by pure white scales. Hindwing brownish-grey, centrally hyaline, 
transparent. Under surface light brownish-grey, both wings only along the costal margin more densely scaled 
white and brown.“ Mashona Land. Damara Land. 
G. flaveola Closs. <$. ,,Thorax, head, and forewing pale ochreous, forewing with two very faint flaveola. 
subbasal transverse bands, two similar postdiscal ones and a strongly notched submarginal pale grey one. The 
anal-marginal portion of the cliscal area between the two inner bands slightly powdered with reddish, the stigma 
is a tiny black dot. Abdomen beautifully bright yellow with thin black ringlets; the shaggy anal tuft is of 
the colour of the thorax. Hindwing pale yellowish, the basal and anal portions bright yellow.“ Senegal. 
G. delicatula Auriv. <$ (39 d). Colouring and marking above to be seen from the figure. Wings delicaiula. 
beneath darker, blackish-grey with whitish veins; forewing in the centre whitish; hindwing as above at the 
hind-margin yellowish. 9 unknown. Gold Coast. 
G. rubroaraalis Wichgr. <§. Rather plainly tinted greyish-brown with darker markings, but conspicuous rubroana- 
by the characteristic contours of the forewings and a large tuft of long scales on the outer half of the 
anal margin of the forewing, as well as by the bright red anal tuft of the abdomen. The feebly undulated distal 
margin of the forewing suddenly projects a little at vein 4; the reddish-brown ground-colour speckled with 
grey scales is distally somewhat lighter, whereas the very narrow fringes are again darker. The first transverse 
line is dark zigzag-shaped and extends from the first third of the costal margin to the centre of the anal margin; 
' a blackish-brown, oblong discal dot; the second transverse line from the centre of the costal margin to the second 
third of the anal margin projects the farthest distally at the stalk of the veins 6 and 7. Hindwing at vein 7 
sharply angular. Abdomen above blackish lustrous, the base of the rings with a reddish tint. Expanse of wings: 
64 mm. £ unknown. Cameroon. 
G. idakum B.-Baker. unknown. $ head, frons, and last abdominal segments light orange-grey; idakum. 
thorax and abdomen light ochreous grey. Forewing light ochreous grey finely speckled with dark grey; costal 
margin and an expanded preapical spot ashy grey; traces of a fine, undulated, grey median line; a similar post¬ 
median transverse line; submarginal line irregular, slanting, and formed by nebulous spots; a black discal dot. 
Hiudwing uni-coloured light straw-colour. Expanse of wings: 60 mm. Nigeria-Lagos. According to Lamborn, 
the larvae are light green with a black dorsal band and clothed with short hairs. Thoracal legs bright scarlet. On 
being disquieted, the larva throws its front body up and backwards so that the forelegs are upturned. It is 
questionable whether it is really a Lasiocampid larva. 
25. Genus: gen.nov. 
The large species upon which this genus is founded was formerly regarded as a Gastroplakaei s. It differs, 
however, obviously from the latter in vein 9 of forewing terminating into the distal margin, and the basal cell 
of the hindwing exhibiting a strong accessory vein. Moreover, the stalk of the veins 9 and 10 of the forewing 
is much longer than the veins. 
D. maputuana Wichgr. <$ (39 d). It suffices to refer the reader to the figure; the thorax is above not maputua- 
unicoloured but speckled by wliitish-grey and brown scales. Distal margin of hindwing feebly bent. The $ is n ' 
much larger (130 mm) and differs in a much smaller discal dot of the forewing and a more bent distal margin 
of the hindwing. Portuguese East Africa: Maputo Land. 
26. Genus: IMapalpus Strand. 
An interesting genus chiefly distinguished from Gastroplakaeis by the marks mentioned in the table 
of genera, but exteriorly of a different habitus somewhat similar to the species of Odontocheilopteryx. 
Palpi porrect, projecting beyond frons, last joint sloping (3) or longer and more porrect ($). Eyes bare. 
Antennae with moderately long, distally gradually shortening pectinations which are in the $ somewhat shorter 
than in the Hind tarsi distinctly hairy. Forewing short and broad with an obtuse apex and a bent distal 
margin, at the centre of the anal margin clothed with long scale-hairs; veins 4 and 5 separate, 8 from the stalk 
of 6 and 7, 9 and 10 on a long stalk, shorter than their stalk, 9 into the apex. Hindwing with an almost 
straight costal margin and a bent distal margin: veins 4 and 5 stalked, basal cell broad, but rather short, 
without developed accessory veins.
