C. dacena Hew. (80 c) very closely agrees with corduba in size, shape of the wings, and colouring, dam.n. 
and is probably the <£ of it. Both the species are also known from the same districts, dacena is distinguished 
from all the other species of Caenides by the dentate white marginal band on the hindwing above. Sierra Leone 
to Gabun. 
C. dacenilla sp. n. Of this new species there are two entirely similar from Cameroon before me. dacmUla. 
Both wings above blackish-brown; forewing with two small, quadrangular, whitish hyaline spots in the discal 
cell, which are only separated by the fold, a dot in 3 and one minute dot each in 6 and 7, beneath at the apex 
arrd anal margin lighter greyish. Hindwing without spots, above irr the discal cell with a large black hair-pencil 
showing distally, beneath at the margin somewhat lighter. Abdomen haired dark brown; palpi with intermixed 
light grey scales. Antennae blackish; tip of the club long, bent down, yellowish-brown. Expanse of wings: 
34 to 36 mm. 
C. hidarioides Auriv. (= artopta Drc.) (80 a) differs from the of the following species particularly hidarioldm. 
by the dark, unspotted underside of the hindwing and the smaller hyaline spots of the forewing. Cameroon 
to Congo. 
C. caenira Hew. ($ = calpis Plotz ) (79 lr, 80 c). The sexes are very different. In the the hyaline caenira. 
spots in 1 b, 2, and the discal cell are large and united into a transverse band, and the hindwing beneath shows 
a coherent, broad, white median band which is dusted with violettislr-reddish and indistinctly defined. In 
the $ (79 h, 80 c), however, as the figure shows, the hyaline spots of the forewing are smaller and separated, 
and the hindwing beneath lacks the coherent median band. Cameroon to Congo. — ceucaenira H. Druce is ceucaenira. 
unknown to me. It is described as follows. <$. Closely allied to C. caenira. Upper surface lighter and the 
pearl-coloured transverse band of the forewing much narrower and parted by the brown veins. On the under 
surface the light part of the wings is much more extensive and without the reddish-violet dusting in the apical 
region. Thorax, abdomen, palpi and legs dark brown. Congo: on the Upper Kassai. 
C. orma Plotz (79 k) is a very different and easily recognizable species. The fringes of the hindwings orma. 
are yellow behind the vein 3. The white transverse band of the hindwing beneath varies a great deal in width 
and may sometimes be almost linear. Togoland to Ogowe. 
C. iricolor Holl. (80 e) has been fully described in the review of the species. Cameroon to Ogowe. tricolor. 
C. latercula IIoil. (79 k) is very similar to iricolor, but smaller and without the yellow markings, Icdercula. 
Ogowe. 
C. sextilis Plotz (79 k), figured from Plotz (XX, plate 1352), is unknown to me. The description is sexlilis. 
short: ,,Dark brown, beneath blackish-grey, only towards the anal margin of the hindwing a little duller. 
Forewing somewhat pointed, hindwing also at the anal angle rounded. 15 mm (length of forewing).“ Gold 
Coast: Aburi. 
C. proxima Plotz (79 k). Whether this species belongs to Caenides, is uncertain. Plotz only describes proximo. 
it with the following words: ,,Dark brown. Forewing above on the marginal half huecl copper-red, beneath 
towards the anal angle dull brown; in the cells 2, 3 and 6 very feeble hyaline dots as in parvipuncta H.-Schdff. 
Fringes yellowish-brown. 15 mm. West Africa.“ The figure is said to have been copied from Plotz’ figure, 
but it does not agree with the description *). 
C. malthina Hew. (= euryspila Mob.) is easily recognizable by the marking and, owing to the malthina. 
formation of the antennae, it belongs to Caenides and not to Parnara. Forewing above blackish with a double 
hyaline spot in the discal cell and 6 or 7 similar discal spots, one each in 2 to 4 (5), 6 to 8. Hindwing on 
both sides with a broad, white or whitish median transverse band, which is above situate in the areas (1 c) 
2 to 4 and beneath between the veins 1 b and 6, without any other markings. Sierra Leone to Gabun. 
9. Genus: Semalea Holl. 
This genus is very feebly characterized. From Caenides with which it agrees in the formation of the 
antennal club, it only differs by vein 3 of the forewing generally rising very near at vein 4, and from Parnara 
only by the longer tip of the antennal club. Neither is the position of vein 3 of the forewing always the same 
in the species of Caenides.
