is invariably absent. In the bind wing the subcosta (vein 8) may be fused with the anterior edge of the cell 
for a short or greater distance ( Homoeomeria ), whereby a resemblance to the Arctiids is produced. Of great 
importance for the identification of the species is the position of vein 4 in the hindwing, which may be situate 
nearer at vein 5 or vein 3. The antennae are almost invariably pinnate, in the <$ mostly rather long, in the 
$ shorter. The palpi have 2 or 3 joints, being covered with shaggy hair or smooth, rarely very long (Marbla). 
The tibiae and tarsi are covered with appressed or projecting hair; the hind tibiae have 1 or 2 pah of spin’s, 
whereby very similar genera such as Liparis and AclonopJilebia can be separated. The tibial blade of the 
forelegs is mostly very long and characteristic of the genera; in future researches this mark ought to be par¬ 
ticularly taken into consideration. Certain genera exhibit the abdomen above provided with a number of dorsal 
hair-tufts. Proboscis absent. 
The majority of the species described has not always been ranged in the correct genera, whereas some 
genera are so very similar that species occur forming transitions. Even in very large collections of museums 
a completeness of the species is impossible owing to the enormous material. For this reason it could neither 
be ascertained in all cases, whether all the species belonged in fact to the genera to which they were placed, 
particularly in the Euproctis , Lcicipa, and Porthesici, Dasychira and Laelia. On the other hand, it may be possible 
that some more Lymantriidae were described in other families, for instance as Geometrids, as has been the case 
with Euproctis ( Soloe ) bigutta (22 e). Thus there remains rather much work that will have yet to be done with 
the African Lymantriidae, and the following classification is to be considered merely as a provisional one. In 
the Lymantriidae there occur quite similar species in quite different genera, and on that account it is to be 
recommended in identifying an insect not only to consult the figure, but also to compare the diagnose of the 
genus. For the correct identification the keys by Aurivillius (Arkiv for Zoologi vol. II, No. 4, p. 62) and 
Janse (Annals of the Transv. Museum vol. V, p. 3) are of immense value, though many a new genus has been 
added in the meantime. 
1. Genus: ISnzfsii Wlcr. 
«r, 
Hind tibiae with 2 pair of spurs; forewing with a long accessory cell which is behind almost open, vein 
11 separate, 10 on a long stalk with 7 to 9; in the hind wing 6 and 7 are separate, cross-vein between 8 and the 
anterior edge of the cell almost in the centre of it. 
B. perculta Dist. Body ochreous-yellow, like forewing; the latter at the apex and distal margin 
broadly black, also the veins in the apical third black. Hindwing with a black marginal area, veins near it 
also black. Beneath the black markings are less distinct. Expanse: 26 to 30 mm. Transvaal. 
B. phaeophlebia Hmps. Head, collar, and tegulae deep orange, thorax yellowish-white. Palpi, chest, 
femora, and abdomen yellowish-orange, tibiae yellowish-white, above striped blackish-brown. Forewing, 
yellowish-white, veins thinly dark brown. Hindwing pale ochreous, veins in the distal part finely dark brown 
Under surface with yellowish-orange costal margin, the terminal area being suffused with brown. Expanse: 
40 mm. Congo. 
2. Genus: Siilgmotisi Wkr. 
Cell of forewing without an accessory cell, vein 10 separately from the cell, vein 7 rises before the centre 
of the stalk of 8 + 9. In the hindwing vein 8 touches the anterior edge of the cell only in one place or it is 
connected with it by the cross-vein. Veins 6 and 7 rise from the same place, 4 and 5 are nearing each other. 
Palpi distinct, pointed; hind tibiae with 2 pair of spurs. -— Chiefly white species; as the descriptions are often 
insufficient, some of the following species will perhaps have to be ranged with other genera, e. g. Homoeomeria. 
Cf. Vol. II, p. 123. -— From the Indian and American regions the genus has not yet been mentioned. 
St. luteipes Wkr. (= laba Schs. & Clem.) (20 a). Wings lustrous white, forewing with a more or 
less distinct ochreous-yellow costal margin, at least on the under surface, particularly in the $. Head in front 
and legs ochreous-yellow. From Sierra Leone to Angola, also in Central Africa and Fernando Po. 
St. flavifrons Hmps. As the preceding species, but anterior and middle legs striped brown. British 
East Africa. 
St. purissima sp. n. (20 a) is separated from luteipes by a white frons, more intense gloss on the forewing, 
and a more densely scaled hindwing. Wings of a pure white, without ochreous areas. 2 $$ from Cameroon 
in the Berlin Museum. 
St. ogovensis Holl. (= nitida Swh.) (20 a) is similar to luteipes, somewhat larger, with a more intense 
gloss. Forewing with a few duller oblique stripes, if the light strikes it obliquely. Costal margin and fringe 
ochreous-yellow. In the whole of West Africa as far as the Transvaal.
