B. Forewing above in the discal cell with but one small hyaline spot at the anal angle. Hindwing above without 
a spot in the discal cell, but with two triangular hyaline spots (in 2 and 3), beneath with a straw-coloured 
ground-colour. Forewing only in 1 b, 2, 3, and 6 with small light.discal spots. G. subflavidci. 
G. afikpo H. Drc. (77 d) is somewhat larger than the other species and differs from all by the discal ajikpo.

G. aburae Plotz (77 b, 79 c). The spots in the discal cell and the discal spots 2 and 1 b of the forewing aburae. 
above are in this species in a straight line. Gold Coast to Gabun. — diversata Holl. only deviates from the diversata. 
type by its lighter under surface. Ogowe Valley. 
G. mocquerysi Holl. (77 c). The discal spot 1 b of the forewing is situated much more towards the mocquerysi 
base than the discal spot 2. Hindwing beneath with small black marginal spots and three black dots in area

G. aretina Hew. (= dolus Plotz) (77 c) is the most easily recognizable by the under surface of arelina. 
the hindwing. Togo Land to Gabun. 
G. subfacata J\Iab. (77 b). This species also differs from the other species by the marking beneath, subjacala. 
The apex of the abdomen is not white as it is incorrectly set forth in Holland’s figure. 
G. vosseleri Griinb. (77 e) is unknown to me, but according to the figure of the underside it can vosseleri. 
probably be ascertained. $. Forewing above only with three hyaline spots, 2 in the apex of the discal cell and 
one in area 3. The $ besides shows there a discal spot in 1 b and 2 or 3 small subapical dots in 6 to 9. 
East Africa near Amani. 
G. johnstoni Btlr. (77 b). Forewing above with 6 small hyaline dots, 2 in the discal cell and one each johnstoni. 
in 2, 3, 6 and 7, beneath besides with a fine white longitudinal streak at the anterior edge of the discal cell 
and a discal spot in 1 b. Hindwing above spotless, beneath coloured dark with a dark brown band and a 
violettish-grey longitudinal stripe at vein 1 b. British Central Africa and Gabun. 
G. minima Holl. (77 c) is extremely similar to johnstoni, but still somewhat smaller and with a minima. 
somewhat different under surface, both wings showing rounded dark submarginal spots, without a white longi¬ 
tudinal streak in the discal cell of the forewing. French Congo. 
G. indusiata Mab. differs rather considerably from the other species. Forewing above black with 7 indusiata. 
small hyaline dots, 2 in the discal cell, a somewhat larger one in 2 right behind those of the cell and one each 
in (1 b) 3, 6, 7, 8, which are also situate almost in a transverse line, beneath somewhat lighter, at the costal 
margin yellowish, before the apex lighter grey, and in 1 b with a large whitish diffuse spot; fringes grey. 
Hindwing above black without hyaline spots, but with a white, about 2 mm broad, interiorly dentate marginal 
band between the anal angle and vein 6; fringes long and white. Cameroon. 
G. subflavida Holl. (77 b) is easily ascertained by the review and figure. East Africa: Usagara. subflavida. 
10. Genus: Serial on 4 k ura Mab. 
Only different from Gorgyra by vein 2 of the forewing and the adjoining part of the median being 
expanded into two adjoining, lustrous white vesicles. Palpi horizontally porrect. The only species is not 
lying before me. The peculiar thickening of vein 2 and of the median on the forewing probably occurs 
only in the <$. 
Oe. lieteroclirus Mab. exactly corresponds with Gorgyra aburae (77 b) in the size, shape of wings and lietcrochrus 
macular marking on both wings, and only differs by the hindwing being on both sides at the proximal margin 
broadly whitish; hindwing otherwise beneath with a yellowish ground-colour, the forewing beneath being also 
yellowish at the costal margin and apex. In Mabille’s figures there is nothing whatever to be discovered of 
the swollen veins of the forewing. They may be West Africa. 
II. Genus: Gastrochaeta Holl. 
Closely allied with Gorgyra and only different by the somewhat shorter point of the antennal club, 
the short, erect terminal joint of the palpus, and in the marking by the hyaline spot 2 of the forewing being 
more removed towards the margin. The hyaline spots are otherwise the same as in G. aburae (77 b). 
Review of the Species. 
A. Forewing with a small hyaline spot in area 4 being situate in a line with the hyaline dots in 6 to 8. 
Hindwing above with a hyaline spot in the discal cell and two or three not transparent whitish discal spots 
in 2 to 4. G. meza.
