S. lasea Drc. (22 i) is quite similar to Pirga magna Swh., but the hindwing is white, only the fringe lasea. 
and sometimes the extreme margin brownish. Sierra Leone. 
57. Genus: Aiiexotamos gen.nov. 
In the habitus similar to Piiga, but in the forewing 11 rises from the accessory cell. Vein 10 rises about 
in the centre, 9, 8 and 7 from the end of the accessory cell, 6 from this cell near the base. 1 and 5 separate, 
the posterior angle of the cell in both wings much more distally produced than in Somatoxena, hindwing otherwise 
as in the preceding genus. In Lacipa, where in the forewing 11 rises also from the accessory cell, the veins 5 
and 4 of the hindwing are forked. 
An. flavibasis sp. n. (22 h) is quite similar to Somatoxena lasea Drc. (22 i) but smaller; hindwing in flavibasis. 
the basal half ochreous-yellowish. $ type in the Berlin Museum (Emin Pashah Habitat unknown, presumably 
in the East African Lake District. 
58. Genus: Marbla Swh. 
Palpi very long, projecting far beyond the frons. Hind tibiae with 2 pair of spurs. In the forewing 
there is a large accessory cell, vein 11 separate, vein 10, 7, 8 and 9 from the accessory cell, 6 distinctly separated 
from it. In the hindwing 6 and 7 are separate, 4 nearer to 5 than to 3. Characterized by the very long 
accessory cell of the forewing. 
M. divisa WTcr. (22 i). Body light ochreous, wings diaphanous white, apical third of forewing and divisa. 
an apical spot of the hindwing black. Madagascar. — The West African race: tenera Holl. (22 h) is a little tenera. 
larger, expanse more than 30 mm in the $. Gabim. The extent of the black markings in the hindwing is 
very variable. 
M. indentata Holl. (22 h) resembles divi.sa, in the forewing the black apical third exhibits a proximal indenlata. 
dentiform projection on the posterior edge of the cell, and a more feeble one on 1 b. The black apical spot 
sometimes occupies the whole distal margin. May be a northern race of divisa. Sierra Leone, Cameroon. 
M. nyctemerina Rbl. Forewing smoky grey, in cell 1 b with a white ray coming from the base, not nyctemeri- 
extending into the cell in front. Hindwing white with a smoky-grey marginal band of 4 mm width, though na 
narrowing down towards the anal margin. Expanse: 43 mm. East Africa, Morea. 
M. elegantula -sp. n. (22 i) is larger than indentata, wings not white, but darkened greyish, in the hindwing elegantula. 
the black distal margin extends to the anal angle, equably broad, proximally somewhat obsolete. Vein 11 of 
forewing rises from the same place with the accessory cell. $ type in the Berlin Museum. Central Cameroon. 
M. proxantha Holl. (22 i). Body yellowish-white, beneath white, legs uni-coloured. Wings hyaline, proxantha. 
forewing yellowish-greyish, costal margin light brown; hindwing and under surface purely white. Gabun. 
M. beni B.-Bak. (21 c). Body somewhat yellowish. Forewing milky white, sometimes hyaline, beni. 
Forewing with a black spot on the cross-vein and a similar one at the rise of vein 2. Congo State. 
M. azami Kheil. Forewing grey, hindwing white, body yellowish. Expanse about 40 mm. Spanish azami. 
Guinea. Very near to M. proxantha , perhaps identical with it. 
M. lindblomi Auriv. (21 d). White, wings almost transparent, without markings. British East Africa, lindblomi. 
M. hemileuca Rbl. (= semihyalina Joic. & Talb.) (21 d). Body yellowish, wings whitish hyaline, hemileuea. 
forewing in the apical portion as far as the cell black, at the cross-vein and at the rise of vein 2 a black spot. 
Beni (East Africa). 
59. Genus: MarMoides gen.nov. 
Consistent with Marbla, but vein 8 in the hindwing as far as the middle of the cell connected with the 
anterior margin of the cell, then slantingly angled towards the costal margin, as it occurs in certain Geometridae 
from which this genus differs in the absence of the proboscis and chaetosema and a different tympanal organ. 
(Genotype: M. paradoxa Her.). 
M. paradoxa sp. n. (22 i). Body yellow, antennae black, legs white. Forewing white, apical half paradoxa. 
and base of costa black. Hindwing white, at the distal margin somewhat blackish, but also there the fringe is 
white. The white places are hyaline, in the forewing in the cell, in the hindwing at the posterior edge of the 
cell creamy yellow. Beneath in the forewing only 1 / 3 at the apex black. Ivory Coast, ^ type in the Berlin 
Museum.
