a little more reddish. The are somewhat larger and lighter, and their forewings not darkened at the costal 
margin and base; the proximal transverse line is therefore much more distinct than in the <J. The larva has 
a bluish-grey ground-colour with reddish segmental margins and is above and laterally scantily clothed with 
long light hairs; the segments 2 to 6 are besides decorated with transverse pads of dense black hair; of these 
transverse brushes there are three on the second segment, one on the sixth, and two each on the segments 
3 to 5; the segments 6 to 11 exhibit above in the centre two adjacent or united greyish-blue tubercles scantily 
clad with long hairs. Thus the consistency between this larva and the larva of the palearctic A. obsoleta King 
having been described and figured by Klug (Yol. I, p. 163) is very great. 
A. schonheiti Wichgr. is apparently closely allied to the preceding species. „<$. Upper surface. Fore¬ 
wing: ground-colour almost flesh-coloured greyish-pink; three faded grey transverse bands before and behind 
the indicated cellular spot, the distal one extending from vein 6 to vein 1, and a submarginal one composed 
of spots in the areas, 2 mm distant from the distal margin^ at the apex somewhat nearer and inwardly bent. 
Costal margin and base darkened by reddish hairs. Hindwing in the centre and at the base lighter, reddish- 
violet at the costal margin and anal angle. Forewing beneath: cell and anterior portion of vein 6 distinctly 
defined grey; the pink colour is posteriorly lighter yellowish. Hindwing beneath yellowish-white, only at 
the costal margin and posterior margin reddish violet. Fringes also violet.“ ,,$ corresponding though without 
the grey darkening of the forewing beneath.“ Expanse of wings: <$ 25, $ 35 mm. Portuguese East Africa. 
A. swierstrae Auriv. (37 b). unknown. $ body and legs blackish-grey; abdomen above somewhat 
lighter; patagia feebly rust-coloured. Forewing above grey without transverse lines, but with an indistinctly 
defined blackish median band and a short rust-coloured oblique band from the base of the costal margin to 
vein 1; marginal portion feebly lighter reddish. Hindwing above and both wings beneath dark grey; hind¬ 
wing with traces of a darker median line. Expanse of wings: 32 mm. Portuguese East Africa. 
A. jansei sj). n. (40 d). A- Both wings above and beneath reddish-grey, above more grey, beneath more 
reddish. Forewing with a red-brown spot at the cell-end and three red-brown transverse lines; the first sub- 
basal one is indistinct, the two others distinctly prominent, notched, and almost parallel; fringes reddish. 
Hindwing above in the centre broadly reddish. Antennae light yellowish. Abdomen with light fawn-coloured 
hair. $ unknown. Transvaal: Pretoria. 
Species with fringes of the forewings, that are light-spotted at the ends of the veins, the ground-colour varying 
from grey to blackish. 
A. uudata Klug has already been described and figured in Vol. II (p. 162, pi. 26 d). It is uncertain whether 
it also occurs within the Ethiopian Region. Sudan ? 
A. af finis Auriv. (37 c) is similar to A. undata, but differs, as the figure shows, in the submarginal line 
of the forewing being deeply bent towards the base at vein 5, and the distal white border of the discal trans¬ 
verse line being expanded at the posterior margin into a spot. $ unknown. Orange Colony: Bloemfontein. 
A. fuscofasciata Auriv. (37 c). unknown. The $ is very similar to the European Trichiura crataegi. 
The colouring and marking above is shown in the figure. Wings beneath brownish grey, at the distal margin 
lighter, with a joint bent dark median band. Natal: Durban (discovered by G. F. Leigh). 
A. definita B.-Bak. was described as Trichiura, but compared with obsoleta Klug, and is certainly an 
Anadiasa. Head and thorax iron-grey; antennae ochreous; abdomen grey. Forewing dark grey with an 
irregular antemedian transverse line being angular towards the margin behind the discal cell; the postmedian 
white transverse line is notched and sometimes proximad angular at the centre; the median area situate be¬ 
tween these transverse lines is much darker than the rest of the wing; traces of a dark notched submarginal 
line. Hindwing grey, with a postmedian broad light band almost reaching the hind-margin at the anal angle. 
Expanse of wings: 27 mm.“ White Nile. 
A. griseata Warren and Rothsch. is declared to be closely allied with sobria (Walk.) and obsoleta (Klug), 
but likewise ranged with the quite different genus Odontocheilopteryx. „<$. Forewing grey, in the median area 
darker; the basal transverse line is blackish, undulated, on both sides bordered with white; the discal trans¬ 
verse line from the costal margin to vein 6 obliquely extending distally and then obliquely proximad, bordered 
with white, particularly at the costal margin and posterior margin, where the white colour is accompanied by 
a dark line; the submarginal line is dentate and blackish; ground-colour between the discal and submarginal 
line often brownish. Fringes at the base with light and dark grey spots; at the end of the submarginal line 
a blackish anal-marginal spot. Hindwing above light greyish-yellow, fringes grey, at the anal angle blackish. 
Beneath the basal half of the forewing is dark grey with a light spot at the end of the discal cell, and with 
a light spot at the costal margin; marginal half light grey. Hindwing beneath light grey with a curved dark 
median line and a dark spot at the anal angle. The $ is light smoky grey, at the base and posterior margin 
with three undulating dark grey postmedian transverse lines; beneath light grey. Expanse of wings: $ 24 mm; 
$ 35 mm.“ Sudan and on the Atbara River.
