ACHAFA. By M. Gaede. 
36. Genus: Aehaea Hbn. 
Proboscis and palpi normal. Antennae of ciliated, strongly pectinated only in the first species. Ab¬ 
domen with short basal tixfts. Middle and hind tibiae with spines. A genus consisting of more than 50 almost 
purely African species. Type: melicerfa Hbn. distributed throughout the Indo-Australian Region as far as the 
celelxrated Easter I.; a characteristic lepidopteron of the coasts of Tropical Asia. 
pccibiicor- A. pectinicornis B.-Bab. (27 d). Size and shape of wings almost as in Parallelia fri2)Iocy7na (29 d), but 
the whole forewing broader and the margin more convex, the oblique streak before the apical third of the fore¬ 
wing and the strigiform spot before the anal angle of the hindwing whiter. Thorax and forewing brownish 
ochreous and red-brown, darker in the median area. Interior line double, black, obliquely outward, vertical 
from the centre of the wing, the branclxes rather far separated. Reniform macula rusty brown, narrow, in¬ 
distinct. Exterior line whitish, tliick, oblique, somewhat double as far as vein 6, then finer, sharply bent in¬ 
ward at vein 6, and vertically on to the inner margin. At some distance before it traces of a dark line. Sub- 
marginal line fine white, xmdulate, distinct only at the costal margin. Hindwing smoky brown, lighter at the 
base, at the anal angle the beginning of a white line. 38—45 mm. Congo, Cameroon, Central Africa. 
1. ^liddle tibiae of d widened, enclosing a cavity and a liair-pencil. iVIiddle tarsi not hairy. Tlie two species 
of this group are very similar, the first has a very hairy base of the hindwing, the other only shows the base at the 
inner margin of the forewing hairy. 
iUi(.<<irafa. A. illustrata Wbr. (= mabillii Saalm.) (26 f). Thorax rusty brown, abdomen brown. Forewing greyish 
brown with a violet reflection, a white dot at the base. Interior line dark brown, oblique, somewhat concave 
in the middle. Reniform macula narrow, edged with black. Median line dark browm, undulate, far excurved 
behind the cell, from vein 2 vertically to the inner margin. Exterior line dark, notched from near the apex to 
vein 2, somewhat excurved between, then yellowish, finely dentate, vertical to the inner margin. This line is 
surroxxnded at the costal margin by a large white spot, divided by the veins and a transverse line, a white spot 
before it beloAv vein 2 and a small one above and below it. Hindwing greyish brown, darker in the marginal 
area. A wdiite square at the apex, and white below it at the margin. The $ shows a less distinct marking. 
50—65 mm. West Africa. A similar specimen is at hand from Madagascar from the Senckenberg Museum. 
dasj/ha.'^lH. A. dasybasis Hnvps. seems to differ in the absence of hair on the hindwing and an irregularly running- 
interior line. The median line is not so far excurved behind the cell, the exterior line is less distinct. 60 mm. 
East Africa, Rhodesia. 
2. Hindwing of with a fine hook at the base of the median vein and a horny plate at the base at tlie 
costal margin. The S produces a sound in flying. 
mormotde.^t. A. mormoides Wlr. (= mania F/dr.) (27 a). Body and forewing reddish brown, the median area some¬ 
times lighter. Interior line distinct, black, straight, mostly light-edged outside. A large black spot at the cross¬ 
vein and a small one below it; they may be fused. Median line undulate, excurved behind the cell, double, rather 
indistinct. Exterior line more excurved between veins 6 and 4 than the median line, single, dentate, blackish. 
Submarginal line light, dark outside, almost straight, lighter behind it, obliquely dark only at the apex. 
Hindwing lighter or darker brown. A faded light line excurved from the middle of the costal margin to the 
inner margin near the anal angle. A fine whitish submarginal line from the anal angle to vein 2. Variably broad 
white at the apex, the margin below' it narrowly light. 60—66 mm. West, South, and East Africa. — 
schiUzei. schutzei Bryl', from Nigeria, differs only in very fine dots replacing the reniform macula, and is therefore hardly 
entitled to receive a special name. 
rcguJaridia. A. regularidia Strd. (27 a) is very similar to mormoides in colour and size. The interior line, how'ever, 
obliquely outward, undulate as far as below the cell, then somewhat steeper. The two dots of the reniform macula 
equally large. The median line also double, but parallel to the exterior line, just as strongly bent as the latter. 
The indistinct light submarginal line in the darker marginal area more extra-angular at vein 7, much nearer to the 
margin than in mormoides. The tw'o lines on the hindwdng very indistinct. 56—64 mm. East Africa, Abyssinia. 
3. Wings of the d normal. 
prucsiaiia. A. pracstans Gn. (= bryoxantha Hnvps.) (27 b). Rather variable. Body dark red-broAvn. ForeAving 
the same, but Avith a variably intense green hue on it. A few dark undulate lines at the base. Interior line 
composed of 2 or 3 branches, vertical, slightly undulated, often also fused. Reniform macula finely edged Avith 
broAvn, with 2 black dots. Median line slightly double, dentate, broAvn, slightly excurved behind the cell. 
Exterior line dark, very oblique from the costal margin to vein 6, strongly edged Avhite outside, then sharply 
iiiAvard, double, filled with Avhite. Submarginal line pale, very dentate, parallel to the margin. A large rusty 
broAvn spot, often bluish Avhite outside, is at the apex behind the exterior line. HindAving dai’k red-broAvn. 
praesianiis. blacker outAvardly, Avith a large yelloAv spot at the apex as far as vein 4. — In praestantis Strd. the basal and mar- 
hrunnescens. ginal areas broAvner, the median area sap-green. — brunnescens Strd. is broAvner, the space betAveen the in- 
rufohrunnea. terior and median lines pale green, Avhitish at the costal margin, the apical spot dark outside. — In rufobrunnea 
Strd. (= arabella Bryk) (21 b) tlie colouring is uniformly red-brown, the marking indistinct, the narroAV median 
lunata. area almost Ai hite. - - lunata Strd. is red-brown Avith Avhite lunar spots behind the median line aliove and be- 
cinercovircn- loAv vein 3. — citiereovirescens Strd. differs from lunata in its greenish grey ground-colour. As the exterior 
ecus.
