Pect. castaneus n. sp. Thorax dark red-brown, abdomen lighter. Eorewing from the costal margin, castaneus. 
in the cell and below it as far as the middle of vein 2, and to the inner margin rusty brown. Distal area 
suffused with violettish-brown. Short black streaks in the distal area. Hindwing similar, but the streaks 
hardly recognizable. 30 mm. Transvaal, type in the Museum of Stettin. 
4. Genus: Corypliodema Fldr. 
Also similar to Cossus. Wings somewhat more elongate. In the forewing of the genotype vein 9 is 
long-stalked with 7 + 8. In the hindwing veins 6 + 7 on a short stalk. Between the antennae no hair-pencil. 
Type: punctulata Wkr. 
Cor. punctulata Wkr. (= capensis Fldr.). Forewing olive brown, at the costal margin darker and as punctulata. 
far as the centre of the wing where the border is formed by an undulate black line. Behind it a curved row 
of spots almost parallel to the distal margin. Then follows a more distinct dark line bifurcating at the costal 
margin. Distal area lighter greyish-brown. Hindwing at the base and inner margin somewhat brownish, the 
rest greyish-brown with traces of a distal dark band. 55 mm. Cape Colony, Natal. 
Cor. ochracea sp. n. (79 e). Yellowish-white, with a brownish ochreous hue, with few black lines on ochracea. 
the forewing. Median line double, distally angled below the costal margin. The distal line is incurved at the 
costal margin, between veins 4 and 3 obliquely outward and nearing the submarginal line. Abdomen and 
hindwing yellowish-white. In the forewing vein 7 is stalked with 8 + 9. $ 25 mm. Luitpold Mts. Type in the 
Tring Museum. 
Cor. albifasciata Hmps. Thorax and abdomen brown. Patagia somewhat whitish. Forewing greyish- albifasciata 
white, below the costal margin at the base white. The cell and a band below it purely white. An oblique brown 
shadow from the lower cell-angle to the submedian fold; there in the centre of the wing a black streak. Marginal 
area with brown reticulate lines, besides 2 stronger lines before the margin which are united above vein 4 and 
despatch rays to the margin at veins 4—2. Hindwing brownish-white. Veins and marginal line brown. As 
veins 6 + 7 arise on a long stalk in the hindwing, the species may belong to the following genus. <$ 30 mm. 
Cape Colony. 
5. Genus : Arctiocossus (Fldr., Jord.) 
Antenna of strongly pectinate to the tip. Between the antennae a hair-pencil. In the forewing veins 
7 + 8 and 9 from the apex, 10 from the anterior edge of the accessory cell. In the hind wing 6 + 7 on a long 
stalk, 8 not connected with the cell by a bar. This refers to the genotype. The species dealt with exhibit several 
differences. Type: antargyreus Fir. 
A. antargyreus Fldr. Thorax and forewing according to the original figure bluish-grey, below the cell antargyreus 
somewhat darker. Thorax in the middle blackish-grey. The cell whitish; at the base as far as the costal margin 
whitish. In the distal area between the veins dark streaks and below the apex dark dots. Abdomen and 
hindwing greyish-brown. 26 mm. Cape Colony. Beside the damaged type no other specimen seems to exist. 
A. punctifera n. sp. (79 e). Greyish-yellow. Forewing below the cell as far as y 3 of the inner margin punctifera. 
rusty brown, behind it at the inner margin whitish. Distal area in the distal half as far as vein 2 rusty brown, 
enclosing dark dots above veins 3—6. Inner angle somewhat lighter. Hindwing greyish yellow. In the forewing 
only vein 7 + 8 and 9 + 10 are stalked; no closed accessory cell. Probably only a casual variation. £ 36 mm. 
East Africa. Type in the Tring Museum. 
A. strigulata n. sp. (79 e). Body and forewing dark greyish-brown, reticulately latticed, at veins strigulata. 
3 and 4 somewhat darker. Hindwing lighter. Veins in forewing typical. In the hindwing 6 + 7 only on a 
short stalk, but vein 8 connected with the cell-end by a thin bar. 28 mm. East Africa. Type in the Berlin 
Museum. 
6. Genus: Molcoceroitles Strd. 
Antennae of not dentate. Wings as broad as in Cossus. In the forewing vein 9 arises short-stalked 
with 7 + 8, the joint stalk being long. In the hindwing veins 6 + 7 on a long stalk. From vein 8 no bar 
proceeds. In both wings veins 4 and 5 nearing each other at the base. The only species entirely makes the 
impression of an Arbelida, but it has 2 inner-marginal veins on the forewing. 
H. ferrugineotincta Strd. (79 e). Thorax brown and rusty brown. Forewing in the basal half dark violet- ferrugineo- 
tish brown, behind it more rusty brown, with rows of dark red-brown spots, being margined with a lighter rusty 
brown. Hindwing and abdomen blackish-brown. $ 28 mm. Spanish Guinea. 
7. Genus: Dmlgeonea Hmps. 
In the rounded forewing veins 8, 9 and 10 from the accessory cell, the others at about the same distances 
from the cell. The lower inner-marginal vein is very straight. In the hindwing veins 3, 4 and 5 almost equi-
