ill the middle. Siibiiiarginal line from the apex to vein 5, inward there, then to the anal angle, rather recti¬ 
linear. Abdomen and hindwing dark lirown. — camerunica Stixl. (20 e) differs in its white interior and exterior 
lines. The angle at vein 5 at the siibmarginal line is thick white, the continuation fine white. Distal area 
lielow vein 5 in the middle bluish white, cj ^2 mm. West Africa. 
30. Genus: Aiiua Wkr. 
IMost of the almost 50 A9t»o-fornis known, as well as the common African tirhaca, belong to the Ethi¬ 
opian Region, if the genus is comprehended according to Hampson whom we follow. The imagines rest on 
the ground during the day; the larvae (only that of tirhaca is known) are apparently not so variegated as those 
of many Ophiasa, but more like those of Catocala, bark-coloured grey above. Food-plants: Cistiis, Pistacia, 
and Rhus coriaria. — Proboscis normal, palpi reaching the frons, antennae of ciliated. Forelegs long-haired, 
middle and posterior tibiae hairy and spined. Margin of forewing slightly undulated. Neuration as hitherto. 
Type: finifascia Wkr. from Transvaal. The genus is also very well represented in the Indo-Australian Region. 
1. Hiudwing of beneath witli liairs at the base and vein 1. 
A. coronata F . (25 a) is widely distributed in the Indo-Australian Region, from Madagascar it is de¬ 
scribed as ponderosa Mah. Thorax and forewing pale red-brown. Two interior lines obliquely outward, two 
exterior lines obliquely inward, dark, parallel in pairs. The large reniform macula is 8-sha])ed. Abdomen and 
hindwing yellow with 2 broad black bands. Numerous forms in the oriental region. 70- -90 mm. Madagascar. 
2. Ilindwing of S at vein 1 without hairs. 
A. pelor Mat). (25 a). Body brownish ochreous. Forewing darker, redder, lighter only around the black 
ring-macida. Reniform macnla with a lighter edge, 8-sha])ed. Exterior line brownish ochreous, very oblique, 
straight. Submarginal line brownish ochreous, beginning near the apex, bent inward at veins 3—5. Darkest 
between it and the exterior line. Hindwdng orange with a l)road black svd)marginal band, the margin itself 
narrowdy greyish brown. ^ 104 mm. Madagascar. 
A. tirhaca Cr. This species has been dealt with already in Vol. 11, p. 327 and pi. 00 f. It occurs also 
in the whole of Africa and IMadagascar. 
Tlie next 4 species are very much alike. 
A. diaiiaris Gn. (24 c). Thorax and forewdng grey, abdomen yellowdsh grey. Forewdng wdth a fine dark 
interior line, undulate, obliquely outward, mostly absent. A fine dot in the middle of the cell. Reniform 
macula brown, with a dark edge and median streak, 8-shaped. Exterior line from a dark spot at the costal 
margin, excurved around the cell, then vertical to the inner margin, rarely discernible. Submarginal line 
whitish, distinct, broadly faded dark brown before it, more pointedly extra-angular at vein 7, more obtusely 
at vein 4, blackish before it. From veins 3 to 5 mostly red-brown at the margin, the rest light grey. Hind¬ 
wing yellow' at the l)ase, the rest blackish. $ wdth a darker forewdng and a broader margin on the hindwing. 
45—55 mm. Sokotra, Abyssinia, East, South, and South-West Africa. 
A. niejanesi Gn. (24 c). Thorax and forewdng red-brow'n, violettish grey at the margin. Interior line 
light, obliquely outward. The ring-macula is a black dot, the reniform macida brown, edged black, concave 
outside. Exterior line fine white, straight behind the cell, oblique, incurved to the costal margin and at vein 2, 
then slightly orrtward, and inw'ard at the inner margin. Srdunarginal line light, similar to dianaris, the pro¬ 
jection at vein 4 almost the same, ending somewhat more obliquely at the inner margin. The space behind 
it dark, ofterr with black scales, therr a blnish-grey shadow. Hindwing browmish ochi’eous, broadly blackish- 
brown at the margin. -- In purpurascens Strd. tire forewing is violettisli grey as far as the submarginal line. 
45—50 mm. Africa and India. 
A. tettensis Hpff. (25 b) is so similar that it may be nrerely a forrrr of piejanesi. Forewdng pale reddish 
brown, darker red-brow n between the exterior line and the srdmrarginal line. At the latter the corirer at vein 4 
is nrrich more rounded. The hindwing is not brownish ochreous at the base, but w'hitish grey. — Some speci¬ 
mens, in w'hich the irrterior lirre descends more steeply from vein 1 and the exterior line has the same shape 
but is situate a little more basad, are probably to be regarded only as aberrations, not as species. Their sub¬ 
marginal line has a short inward angle at vein 3. 40—44 mm. East Africa. 
A. wahlbergi Wllgr. (= tettensis Hnips.) (25 a, b). Aitrivillius states that wahlbergi is an older name 
for tettensis. Thorax yellow', abdomen wdiitish ochreous. Forewdng yellow, darker behind the exterior line. 
Interior line straight, light. The cellular dot, the reniform macula and the follow'ing lines agree exactly w'itli 
tettensis Hpff. The brow'nish marginal spots may be confluent or absent. Hindwing wdiite, slightly brown in 
the interior area, marginal l^and as in tettensis. - In rubicunda Strd. tlie tliorax and forewing are somew'hat 
redder. 36—45 mm. MAst, South and East Africa. — It cannot be decided w'hether e.vpedita IFA-?-. and cawe- 
ronis PJdtz belong to tettensis Hpff. or to tettensis Hmps. 
A. obsolescens Hmps. Body reddisli yellow'. Forewing yellowisli white, especially at the base. A red- 
brown streak at the cross-vein. Sul)niarginal line red-lwown, slightly excurved at vein 6, somewhat red-brown
