A. atrifasciata limps. (80 a). Body brownish-white, thorax with a V-shaped dark brown marking. 
Forewing dark brown. From the base to below the a-pex, and at the inner margin a yellowish-white stripe with 
orange streaks. Hindwing whitish, partly with pale brown stripes. $ 70—80 mm. Nyassa District, Rhodesia. 
A. simplex Am. (79 g). The species is rather isolated, as it looks like a narrow-winged Cossus terebroides. 
Dark grey, on the forewing the black lines are distinct and much farther separated than usual. Hindwing also 
dark. $ 26 mm. Yola. 
A. psyche Le Cerf. Thorax and forewing blackish-brown, without markings. Abdomen and hindwing 
greyish-brown, at the anal angle lighter. In the $ the abdomen is also blackish. 25—34 mm. Dahomey. This 
is perhaps one of the dark species of Phragmatoecia. 
12. Genus: Xyleutes Him. 
Only separated from Azygophleps by the thinner antennae of the The marking is mostly somewhat 
similar to that of Cossus. Type: crassus Dry. 
X. crassus Dry. (80 a). Thorax brown, laterally in front and behind black, abdomen blackish-brown. 
Forewing brown, in the lighter, in the $ very dark, at the base and above the centre of the inner margin 
white, the latter portion outside with a black spot at vein 1. Distal area irregularly defined, white. In it below 
the apex a crescentiform dark band at the distal margin, and blackish marginal spots. Hindwing reddish-brown, 
feebly latticed blackish. 100- 160 mm. Cameroon, Sierra Leone. polyoplaga Hmps. The basal area and 
distal area on the forewing suffused with brown. The light spot above the middle of the inner margin outside 
with a large black lateral spot and also inside with such a spot. Hindwing also with feeble marginal spots. 
C 105 mm. Niger District. lunifera limps, is a smaller form, still more uniformly brown. In the the light 
spot above the middle of the inner margin is also absent, the black distal spot next to it is only small. Costal 
margin with black little strokes, only the black crescentiform line at the distal margin is prominent. 75—95 mm. 
Sierra Leone. In East Africa also 2 races. The smaller one corresponds to lunifera: - - sjoestedti Aur. (80 a) of an 
ochreous ground-colour. Thorax and abdomen finely dusted with black. Forewing finely latticed dark, with 
a larger, somewhat darker spot before the middle of the costal margin, and an oblique spot behind the cell from 
vein 5 to the inner margin. The crescentiform marginal line is brown. Hindwing latticed paler brown. 55—100mm. 
East Africa, Uganda, Natal. Whilst the genuine $ of sjoestedti has the very same colour and marking as the <$ 
and it only occurs in East Africa, the $ described as sjoestedti by Atjrivillius belongs to another form which 
may be denominated vosseleri /. n. (80 b). Body light grey. Wings milky white. Forewing scantily latticed 
black, with olive brown spots at the costal margin near the base, before and behind the middle, as well as 
above % of the inner margin, in the d 1 they may also be absent. Apical band normal. Hindwing also latticed black. 
Both wings less densely latticed than in sjoestedti. 80— 140 mm. East Africa and (more frequently) Cameroon, 
Sierra Leone. Types in the Berlin Museum. 
X. capensis Wkr. W 7 hitish. Thorax and abdomen spotted dark. Fore wing finely spotted (striated?) 
black with a crescentiform line and black marginal spots. Hindwing paler with dark marginal spots. Natal. 
As sjoestedti also occurs in Natal, it may be that capensis was merely a faded specimen of it, though the latter 
name may be prior. 
X. cretacea Btlr. (80 b). Yellowish-white. Forewing in the posterior portion suffused with light brown, 
scantily speckled with black. At the costal margin behind the middle a long black streak and at vein 1 a short 
one. Subapical crescentiform line strong. Hindwing slightly brownish, feebly latticed brown. 65—90 mm. 
Madagascar. 
X. moderata Wkr. (80 c). Body brown. Wings yellowish-brown. Forewing at the inner margin, below 
the cell-end and before the middle of the distal margin browner, densely covered with short black streaks which 
are reticularly united in the marginal spot. Directly behind the cell a large black spot and at the distal margin 
a smaller one. Hindwing in the marginal area latticed black. Margin in both wings spotted black. $ 130 mm. 
Sierra Leone. 
X. geminatus n. sp. (80 c). Head and thorax brownish-white, in the middle probably darker, abdomen 
reddish-brown. Fore wing reddish-brown with short creamy white double streaks, at the costal margin with 
broader light spots. In the centre of the inner margin a large double spot of the ground-colour without light 
streaks. A postcellular spot and the distal margin partly also without streaks. Hindwing dark brown, at the 
costal margin almost yellowish-white. A 100 mm. Cameroon. Type in the Tring Museum. 
The following species are smaller. With radial stripes at the costal margin of the forewing and with spots. 
X. atriplaga Le Cerf. Body and forewing slate-coloured grey, at the cell-end somewhat reddish, with 
black reticular lines between which there are irregular grey spots. These are arranged in 2 rows between veins 
1 b and 5 behind the cell and from the inner angle to vein 6 before the margin. The basal third at the costal 
margin with a projection to vein 1 c black, besides 1 black spot above the cell-end. Hindwing grey, at the anal 
angle lighter, only with feeble traces of darker reticular lines. $ 66 mm. Angola.
