inner margin near the anal angle. Interior line finely blackish brown, violettish white outside. Exterior line 
next to it, somewhat steeper, edged with white on both sides, bent inward, another parallel light line before 
it below the cell. Submarginal line whitish, extending at vein 7 to the margin, then blackish brown, bent inward, to 
the anal angle. Hindwing dark greyish browm, narrowly yellow at the margin as far as vein 4. $ 46 mm. Madagascar. 
A. leucopera Drc. (27 d). Thorax and forewing at the base chocolate brown. The border-line is light, Leucuycm. 
somewhat outward, slightly projecting below the cell. The interior half of the median area is greenish white, 
the exterior half bluish brown. Reniform macula edged with a black streak and black dots. Median line dark, 
dentate, extra-angular at vein 5, bent inward in the submedian fold. Exterior line dentate as far as the sub¬ 
median fold, forming a large bow, below it outward again. Marginal area darker. A rusty brown spot at the 
apex, edged with white inside. Submarginal line yellowish brovm, parallel with the margin. Hindwing blackish 
brown, a white spot at the apex dowm to vein 5. The $ has a red-brown base on the forewing, the rest being 
more reddish, the median area with a violet hue. Hindwing lighter brown. — In deviridata Strd. the green deviridata. 
dusting in the median area has almost disappeared. — banjonis $ Strd. (20 f) has a dark red-brown basal area, banjoniis. 
the space behind it as far as before the submarginal line is uniformly lighter. The interior line is quite straight, 
vertical. Hampson does not mention the latter in leuco'pera. In both the forms the white apical spot of the 
forewing is pointed behind. 45 mm. Cameroon, Congo. 
The two following species are much stronger, similarly marked. 
A. retrorsa {21 e). Body pale red-brown. Forewing chocolate brown at the base. Median line rctrorsu. 
dark, yellowish outside, bent inward from the middle of the costal margin to vein 1, then still more obliquely 
to the inner margin. Paler red-brown behind it, gradually darkening as far as the submarginal line. Reniform 
macula indicated by 2 black dots and a fine connecting line. Exterior line double, faded, bent S-like, some¬ 
what dentate, dusted violettish white inside, the interior branch with a faintly black spot at the inner margin. 
A round spot of the ground-colour at the apex, encircled by dark brown. From vein 7 the inwardly broad dark 
border of the marginal area extends at first inward, then parallel with the margin, bent from vein 2 to the 
anal angle. Marginal area above somewhat white. Hindwing brown, dusted bluish white at the base and on 
a median band from the middle of the costal margin to the anal angle. Besides a light submarginal line near 
the anal angle. 70 mm. Madagascar. 
A. echo Wkr. {= mariaca Plotz) (27 f). Body and base of forewing darker than in retrorsa. Median line echo. 
dark brown from the middle of the costal margin to the middle of the inner margin, uniformly bent inward 
between. Median area very pale red-brown inside, darker outwardly. Two black dots at the cross-vein. Ex¬ 
terior line single, more dentate than in retrorsa, also S-shaped. The border of the marginal area extends from 
the apex, otherwise similarly bent as in retrorsa, very dark before it. Margin pale red-brown, the veins in the 
interior part light, darker between. Hindwing somewhat darker than in retrorsa, otheinvise similar, with a 
white apical spot. 62—70 mm. West and South Africa. 
A. indicabilis Wkr. (27 f). Body greyish brown. Forewing chocolate brown in the basal area in front, indicabiUs. 
greyish brown at the inner margin and in the median area. Interior line whitish, very irregular. Ring-macula 
and reniform macula edged with pale brown. Median line brown, shortly excurved around the cell, then in¬ 
ward to the middle of the inner margin. Exterior line black, dentate, extra-angular at vein 6, then straightly 
inward, greenish before it as far as the median line, dark red-brown behind it. The border of the marginal area 
similar to that in retrorsa. Margin slightly greenish. Hindwing greyish brown, darker in the distal half. 
A white spot at the apex as far as vein 5, a short light marginal and submarginal line from the anal angle.

The following 3 species are lighter on the forewings. 
A. orthogramma Mab. (= sarcopasa Drc.) (27 e). Body yellowish brown, forewing somewhat more 
reddish. Interior line white, edged with grey inside, oblique, straight. Reniform macida formed of two circles 
connected by a bent streak. Median band faded, straight, incurved from vein 3. Exterior line white, edged 
dark inside, vertical, almost straight. Submarginal line indicated by a few dark spots. Marginal area violettish 
white, tapering at the ends. Hindwing pale greyish brown, with a broad black band from costal margin 
to the anal angle, margin broadly blackish, white behind the cell. 46—56 mm. Madagascar. 
A. leucopasa Wkr. (= karschi Pag.) (27 e). Thorax and forewing reddish yellow, somewhat violet be- icucopasa 
hind the median line, feebly rusty brown at the margin. Interior line dark, straight, undulate, rather oblique. 
Reniform macula with 2 black spots, shadowy. Exterior line of 3 parallel branches, the middle one less strong, 
dentate, slightly excurved behind the cell, vertical below vein 2. From the apex an oblique line to vein 6, 
where there is a dark spot, the marghi behind it rusty brown. Hindwing similar to orthograrntna . Around the 
white marginal spot the two black bands are fused. 55—70 mm. Madagascar. 
A. serva F. (= fascicidipes Wkr.) is said to occur also in Madagascar, though it is distributed from India far 
serva. 
into the Australian archipelago. It is larger than the following species or form, quite similarly varying; the bluish 
white median band of the hindwing is interrupted in serva and less faded than in mercator(a. 65 mm. Madagascar. 
A. mercatoria F. melicerta Cr., vulpina F., ino Hbn., accelerans Wkr., serva Mr.) (27 f). Thorax mercatoria. 
and forewing pale red-brown. Interior line indistinct, doiible, undulate, oblique as in leucopasa. Reniform macula
