As the Pompostolinae take here the place of the Asiatic Chalcosiinae being absent in Africa, we have 
also in the Ethiopian Region 4 subfamilies: 
A. Himantopterinae : proboscis and palpi stunted, frenulum absent. Hindwing transformed into a 
long narrow tail. 
B. Phaudinae: as above, but hindwing of normal shape. 
C. Pompostolinae: palpi and proboscis present. On the forewing only one hindmarginal vein. In 
the hindwing vein 8 more or less fused with the cell. Antennae typically Zygaena-\\ke. 
D. Zygaeninae: palpi and proboscis present. On the fore wing two hindmarginal veins. In the hindwing 
vein 8 is mostly connected with the cell by a fillet. 
A. Subfamily: Himantopterinae. 
Proboscis and palpi stunted. Antennae of $ with very long, in the $ short pectinations. All the tibiae 
without spurs. Forewing elongate, distal margin long, passing over in a large curve into the short hind-margin. 
Hindwing very narrow, so that the veins can hardly be ascertained. The larvae of the Indo-Australian species 
are presumed to live with termites. With the Ethiopian species probably the same is the case. For further 
particulars about this subfamily cf. Vol. X, p. 5. The genera exhibit partly 2, partly but 1 hindmarginal vein. 
We begin with the former. 
1. Genus: Himasctopierus Wesm. 
Forewing without small precostal veins, the upper cell-angle projecting very far. All the veins separate, 
3 veins proceeding from the anterior margin of the cell. Type: fuscinervis Wesm. 
fuscinervis. H. fuscinervis Wesm. has already been dealt with in Vol. X p. C and figured there on pi. 1 d. Forewing 
yellow, hindwing dark and filiform. This species described from Java is said to occur also in Africa. It is probably 
a mistake. 
2. Genus: &eiaiio]>tila Btlr. 
In the forewing the 2nd to 4th veins are far remote from each other, vein 5 nearer to 6, 7 + 8 + 9 
forked, 10 absent, frequently also the anterior part of the cross-vein. The species all have dark brown wings 
with an orange spot at the cross-vein. Type: torta Btlr. 
iorta. S. torta Btlr. Proximal half of forewing ferruginous-red. Hindwing uniformly narrow, only in the 
mcishuna. middle slightly widened, where there is an orange spot. — mashuna Rothsch. is paler. Hindwing with a larger 
lobe and a larger spot. Tail half as long as the hindwing is broad at the broadest part. Expanse 22 mm. Congo, 
Mashuna-Lancl. 
ansorgei. S„ ansorgei Rothsch. Body, proximal area of forewing und proximal third of hindwing yellow. Hindwing 
rather unifonnly broad in its whole length, only in the middle and at the end mostly somewhat widened. 
Angola. 
Irogolobci. S. trogoloba Hmps. Forewing almost to the cell-end and anal angle orange, costal margin and distal 
area dark brown. Hindwing with a moderately projecting lobe, below it strongly indented. As far as the lobe 
yellowish-orange, then dark. On the lower part of the lobe an orange spot. Expanse: 20 to 24 mm. East Africa. 
latifulva. S. latifulva Hmps. Forewing in the cell and as far as the margin near vein 2 orange. Hindwing at 
the base somewhat broader, then a long narrow tail; in the first half orange, at % a short yellow streak; below 
it very slightly widened. Expanse 20 mm. East Afiica. 
hilar is. S. flilaris Rbl. V ings of a bright orange-red in the centre and below vein 2. Hindwing only at the base 
a little wider and orange-red there. In the $ also at the apex oiange. Expanse 28 to 30 mm. East Africa. 
flavidiscaia. S. flavidiscata Hmps. (1 b). Forewing in the cell and below it as far as the anal angle yellowish. 
This, however, varies a great deal, sometimes only the hind-margin is light. Hindwing only at the base a little 
wider, in the $ still less. The proximal third is yellow. Expanse 22 mm. Rhodesia, Transvaal. 
lufirensis. S. lufirensis Joicey (1 b). Similar to the two preceding. Hind-margin and cell yellow. Hinclwing at 
the base and end slightly widened. At the base yellow. Expanse 28 mm. South Africa.
