which is somewhat different on both sides. Abdomen and hindwing light brown. $ 50 mm. Madagascar. Type 
in the Tring Museum. /+ 
C. fuscibasis n. sp. (79 c). Forewing from the base almost to the cross-vein blackish-brown, the border¬ 
line indistinct, incurved towards the inner margin. At the cross-vein white scales and below vein 3 white. 
The black distal line flawed at vein 5 and connected there with the anteriorly bifurcated submarginal line from 
which some black streaks extend to the margin. This marking is somewhat different in each of the 4 specimens 
before me. Body and hindwing pale greyish-brown. Antennae of $ strongly pectinate. 40—44 mm. Madagascar. 
Type in the Tring Museum. 
C. aegyptiaca Hmps. (79 c). Body pale reddish-brown. Forewing ochreous brown. The streaks at the 
costal margin, in the cell-end and the centre of the inner margin black. Inner margin and base of cell without 
any marking. Behind the cell light spots between the veins. Between the veins 8—5 and 4—2 without fine 
streaks at the margin. Hindwing white, at the margin a fine brown reticulated marking. $ 45 mm. Described 
from Suez, the figured $ from “Nubia” may belong to this species. In the latter vein 9 of forewing is separated 
from 7 + 8, the antennae being shortly pectinate. 
C. recfangulatus Wichgrf. Forewing silvery grey with 3 dark parallel lines vertical to the costal margin, 
almost straight. The first from the centre of the costal margin to the inner margin. Half way to the apex the 
second extending to vein 3. A little behind the middle of the remaining distance the third to vein 4. this line 
bifurcating in front. Besides many less distinct lines. Hindwing whitish-grey. $ 45 mm. East Africa. 
C. seineri Griinbg. (79 c). Light bluish-grey with few short black streaks at the costal margin of the 
forewing. From % of the costal margin, vertical to it, an undulate line to the anal angle, united with the 
marginal line at vein 3. Hindwing similarly coloured, feebly and finely striated dark. $ 44 mm. Betchuanaland. 
C. senex Btlr. (79 c). Body and wings whiter. Forewing finely striated grey. An interior black line is 
rather strong. Before the middle of the costal margin a black V. Before and behind it from the lower cell-edge 
2 indistinct lines, the distal one forked. From the apex a fine distinct line obliquely inward as far as vein 5, 
then to the margin near vein 2. Hindwing slightly brownish, with a dark reticulate marking. 34—40 mm. 
Madagascar. 
C. fulvosparsus Btlr. (79 c). Forewing greyish-white, striated somewhat darker, with lighter spots 
between. Inner margin as far as behind the base of vein 2 brownish, and often a brownish stripe above the 
anal angle. At the cell-end, behind it and at the margin orange spots. The whole wing and the patagia often 
with a green reflection, thus somewhat similar to the European Folia xanthomista, excepting the size. Head, 
tegulae, and abdomen brownish. Intensely green specimens are: — smaragdinus Btlr. Antennae of the $ thick, 
not pectinate. 40—60 mm. Madagascar. 
C. crassilineatus n. sp. (79 c). $ almost blackish-brown, £ greyish-brown. From before the middle 
of the costal margin a strong, straight black line extends obliquely outward, not reaching the inner margin. 
Behind it an X-shaped marking in which the anterior distal branch is stunted, the branches touching each 
other at vein 5. Behind it a short apical line. Hindwing of the almost black, of the $ brown. 20—26 mm. 
Madagascar. Type in the Tring Museum. albiplagiatus n. /. is presumably only a very light <$ lacking the 
strong oblique median line. The area below the distal portion of the cell, however, is white obliquely inwards. 
Also from Madagascar. 
C. pavidus Btlr. Forewing grey, finely striated black, costal margin with black spots. Below the cell 
in the middle a black horizontal V, and 2 indistinct black spots in the centre of the wing. At the margin 
likewise black spots. Hindwing lighter, in the apical area with somewhat darker striae. 36 mm. Madagascar. 
C. breviculus Mab. (79 d). Body pale brownish. Forewing white, clouded dark, with fine grey and 
black latticed lines. A square reddish-brown spot behind the lower cell-angle and another one above the inner 
margin behind the centre. Hindwing dingy white with a purely white fringe. 25—28 mm. Madagascar. 
C. impeditus Wkr. Owing to the narrow forewing with an oblique distal margin it surely does not belong 
to this genus and is omitted therefore. 
3. Genus: Pectieossus n. g. 
Antennae of $ as strongly pectinate as in Coryphodema. In the forewing veins 3, 4 and 5 are somewhat 
separated, 6 below the upper cell-angle, 7, 8 and 9 from the apex of the accessory cell, 10 from its anterior 
edge. In the hindwing veins 3, 4, 5 somewhat separated, 6 far away from 7, no bar to vein 8.
