crenata. • L. crenata R. & J. Paronychium on each side with 2 appendages. Body and wings greyish tan-coloured, 
the lines in the fore wing umber-brown, not distinct; 4 in the proximal half, between the 3rd and 4th dark 
filling; stigma small. In the disc 3 transverse lines, the 1 st and 3rd composed of basally open demi-bows, 
the 2 nd broad, band-shaped. At the margin a triangular brown spot, a brown dot at the apex and one at the 
tornus. Hindwing with white fringes and chestnut-brown veins, a brown streak at the tornus, towards the 
base edged with whitish-grey; at the anal margin an indistinct brown spot. Expanse: 50 mm. British East 
Africa. 
29. Genus: Poliodes R. u. J. 
Structurally allied to the preceding genus, pulvillus reduced, small and narrow, paronychium on each 
side with but one appendage. 
roseicomis. P. roseicornis R. <£■ J. (64 c). Antennae with pink scales. Body grey. Forewing grey, but centrally 
pinkish whitish-grey, with a triangular costal-marginal spot at the cell-end. Discal line strongly dentate. 
Marginal area behind it and the interior margin grey, at the tornus a whitish spot, a whitish oblique line from 
the apex, towards the costal margin bordered with blackish, towards the termen with brown. Hindwing brown, 
with traces of a thin postdiscal line, and a broader submarginal line which is is more distinct at the tornus, 
blackish. British East Africa. 
30. Genus: Ceriilia R. u. J. 
Anterior tibiae ending in a strong thorn, middle tibiae spined, hind tibiae with a pair of spurs. 
heuglini. C. heuglini Fldr. (=- beuglini Bsdv.) (64 c) is easily recognizable with pink hindwings and pinkish-grey 
forewings with a dark red-brown angular marking. Antennae not pectinate. West Africa, Abyssinia. 
mira. C. mira R. <&■ J . Antennae of and $ pectinate, the angular spot at the costal margin of the forewing 
quadrangularly trapezoidal, posteriorly indented; hindwing pinkish-grey, with an indistinct darker median 
and marginal band, and a postdiscal dark transverse line. Expanse: 45 mm. British East Africa. 
31. Genus: Xeiiosphingia Jonl. 
Allied to the preceding genus, antennae very strongly pectinate, 3 rd palpal joint long and narrow 
cylindrical; anterior and middle tibiae spined; anterior tibiae without, posterior tibiae with terminal spurs. 
jansel. X. jansei Jord. Body and forewings yellowish sap-green. Shaft and outside of pinnae of antennae white, 
front side purple, underside ochreous, palpi and legs partly purple brown. Forewing with a snow-white costal 
margin, in the distal third shaded with dark, the stigma and basal tuft at the interior margin whitish. 3 mm 
distant from the termen, parallel to it, a darker green line. Apex pointed, but not produced. Margin below 
it straight, then convex, tornus rounded off. Hindwing whitish-green, at the anal margin whitish. Expanse: 
36 mm. Rhodesia. 
32. Genus: Acaiitliosphinx Auriv. 
Middle tibiae spined, posterior tibiae with 2 pair of spurs, the longer terminal spur being as long as 
the 1 st tarsal joint; paronychium and pulvillus present. Margin of forewing entire, not dentate. Easily separable 
from Polyptychus by unspined posterior tibiae and the very long tibial spurs. 
giissfeldti. A. giissfeldti Deuiz. (64 c). Margin of forewing in the $ straight, in the $ somewhat concave; forewing 
violettish-grey with brown transverse markings, the marginal area varying between yellowish-green and dark 
olive green. Hindwing darker grey, with an olive green marginal area and in it two darker lines dying away 
gigas. in front. Expanse: 110 mm. in the much larger form: gigas Auriv. 120—140 mm. Sierra Leone to Congo. 
33. Genus: Xjopliostetliiis Btlr. 
Middle tibiae spined, posterior tibiae with 2 pair of spurs, the longer terminal spur half the length of 
the 1 st tarsal joint. Anterior tibia with a long terminal thorn. Pulvillus absent, paronychium present, on each 
side with one lobe. 
demolini. L. demolini Anyas (= dumolini Wh\) (64 d). Easily recognisable by the brown, posteriorly faded and 
narrowed median band of the forewing, containing a silvery white dot and nail-spot. The nominate race is of a 
more yellowish-brown colour, the black submarginal triangle in the forewing between veins 4—6 is longer and 
carteri. extends to. or almost to the white discal line. Natal to Uganda. — In carteri Rothsch. the submarginal triangle 
negus, does not extend to the discal line, the colouring of the wings is greyer. Senegal to Congo. — In negus Jord. the 
forewing shows a more cinnamon-brown tint, and in the white nail-spot the branch showing to the costal margin 
is the longest. Subbasal stripe more prominent. South-West Abyssinia.
