blackish markings. At the apex a short black oblique streak. Hindwing dark red, basally more ochreous; anal 
margin not black. Anal angle dusted with grey, with 3 blackish transverse streaks the exterior one of which 
is continued to the costal margin; marginal area red-brown. Expanse: 20 mm. Kedai, East Africa. It was 
described as Dovania. 
Tribe: Sphingicae. 
Separated from the Acherontiicae by the middle palpal joint not being hollowed out. 
5. Genus: Xaiilliopaii R.u.J. 
Last palpal joint not hidden beneath the scales of the middle joint, but smooth, distinctly projecting 
from it and pointed. The longer one of the two terminal spurs of the hind tibiae is as long as, or longer than 
the tibia. Larva unknown. 
X. morgani Wkr. (61 b). Forewing varying between olive-brown and red-brown, with blackish transverse morgani. 
lines and longitudinal streaks, one of which above and below vein 3 is particularly distinct; at the cross-vein 
with a white macula. Hindwing blackish-brown with a round yellow subbasal spot and a similar spot along 
the greatest part of the anal margin. Thorax beneath white. West and East Africa. — In praedicta R. ds J ., praedicfa. 
from Madagascar, the underside of the thorax is of a pink colour. The proboscis of this race is 22 ]/, mm long; 
the species thus represents that lepidopteron the presence of which in Madagascar has been predicted by 
Wallace, because the blossoms of Angraecum sesquipedale can only be deprived of their honey 
by a form provided with such a long proboscis; he found that X. morgani almost met this requirement, and 
Rothschild and Jordan, on discovering this Madagassic race, ascertained that it was the ,,predicted“ one. 
6. Genus: Panogeiisi R. u. J. 
Near to Xanthopan, but the last palpal joint hidden beneath the scales of the middle joint. Pulvillus 
between the two last claws of the tarsi strongly developed, anterior tibiae spined, posterior tibiae with middle 
and terminal spurs. Paronychial appendages (without the claws) on each side composed of 2 threads. Larvae 
unknown. 
P. jasmini Bsdv. (= chromapteris Stir.) (61 b). Forewing varying from a brownish grey to bluish grey, jasmini. 
at the cross-vein a white spot surrounded by dark, transverse lines and longitudinal streaks blackish. Hindwing 
in the basal third yellow, outside blackish brown, sometimes basally lighter, towards the yellow basal area 
defined by a black transverse line which does not exhibit any posterior expansion or projection. Middle tibiae 
with thorns. Madagascar. 
P. lingens Btlr. (61 b). Forewing mostly more brownish, in the hindwing the black median band is lingcns. 
extended into a dent directed towards the base, distally to it a distinct yellow transverse stripe. Extreme 
base black. Middle tibiae without thorns. Madagascar, rarer than jasmini. 
7. Genus: Poliana R. u. J. 
Separated from the preceding genus by the unspined anterior tibiae. Paronychium on each side only 
with a plain lobe. Proboscis not longer than the body, anterior tarsi with short thorns. The stalk of veins 6 
and 7 on the hindwing is longer than the adjoining part of the cross-vein below it (as far as vein 5). Larvae 
unknown, a purely African genus, though 1 species is described from Cambodia. 
P. buchholzi Pliz. (61 c) (= laucheana Drc., weiglei Mschlr.), Forewing greyish-white, more or less buchholzi. 
powdered with rusty brown, with a few such transverse lines, in the centre 3 black dentate transverse stripes, 
basad to them a rusty brown area around the white macula at the cross-vein. Marginal area more or less 
chalk-coloured, with a blackish dentate submarginal line. Black longitudinal streaks between veins 2 and 4 
are absent. Hindwing blackish-brown, with 2 indistinct darker suhmarginal transverse lines, and a whitish 
brightening near the base and before the anal margin. Anterior tibiae outside at the end with a distinct thorn. 
West Africa, a very rare species. ■— The East-African race: marmorata Fawc. (61 d) is darker, the antemedian marmoraia. 
line more distinct and blackish, the postdiscal band divided into larger spots, the antemedian line on the posterior 
edge of the cell projecting more distad. Masongaleni, East Africa. 
P. micra R. A J. is allied to buchholzi , in the habitus similar to Praedora marshalli, the first tarsal joint micra. 
of the hind legs not longer than the following ones together (in the preceding species one and a half times as 
long). The antemedian and discal lines of the forewing united in the centre as in Pr. marshalli, otherwise 
similar to buchholzi. Length of fore wing: 21 mm. Ganale, East Africa. 
P. natalensis Btlr. (= spei Btlr.) (61 c). Forewing with blackish longitudinal streaks between veins 2 natalensis. 
and 4, of a variable colouring, almost blackish or bluish white-grey, postdiscally often lighter chalk-coloured. 
First tarsal joint of hind legs twice as long as the two following ones together. Larger than the preceding ones. 
South Africa. 1 specimen from Cameroon. — The species is very similar to the Indian Psilogramma menephron Or.
