I append here the following species having been based upon much flown specimens and therefore only incompletely 
described. 
A. simplex Pag. ,,Palpi reddish-brown. Thorax and abdomen blackish-brown. Forewing greyish- simplex. 
brown with an indistinct transverse line. Hindwing lighter greyish-brown, in the posterior margin and anal 
angle shaded darker. Beneath as above.“ Somali Land. 
Note: A. sahariensis Rothsch. (1921), from the Sahara: Ashen, probably does not belong to this region. This genus sahariens 
surely comprises many more African species that have not yet been described. There are about five species before me, which 
are probably unknown, but which cannot be described owing to their bad condition. 
7. Genus: Pseiidometsi Aur. (= Allenella Strand; .= Gastroplakaena Strand). 
Palpi in the $ short, not projecting beyond the frons, in the $ often longer, projecting more or. less 
beyond the frons, and with a longer terminal joint. Antennae with two rows of pectinations which are 
slightly shorter in the $ than in the <$. Hind tibiae with very short terminal spurs. Hind tarsi with appressed 
scales or above scantily haired. Forewing elongate, pointed, with a long curved distal margin, entirely roun¬ 
ded anal angle, and short posterior margin; veins 6 and 7 stalked, 8 from this stalk, veins 9 and 10 shorter 
or rarely about as long as, or longer than their stalk; vein 9 into the apex of the wing. Hindwing at the base 
of the costal margin with a very large lobe, costal margin then straight or emarginated, rarely convex, distal 
margin curved or in some almost straight. Fringes of both wings short, entirely margined. 
Although this genus shows a neuration and shape of the wings very similar to those of some other 
Gonometinae, yet it seems to be a natural one and differs from all the others in the strong development of the 
basal lobe of the hindwing. The £<$ exhibit a coniform abdomen and are smaller than the stout Many 
species are still insufficiently known and their differences are uncertain. 
Ps. basalis Walk. {<$ = acuminata Walk.). Antennae black, with honey-coloured pectinations. Fore- basalis. 
wing above fawn-coloured, at the posterior margin red-brown, slightly mixed with grey, with an antemedian 
and a postmedian transverse line, which are particularly in the <$ very indistinct; the distal transverse line 
is composed of dark, distally concave bows; the submarginal line is represented by round black dots which, 
however, are generally only distinct in the areas 6 to 8, and may also be indistinct there in the $. Hindwing 
above grey (d 1 ) or fawn-coloured with traces of a darker median band ($), beneath somewhat lighter, often 
yellowish, with a distinct median band and darkened blackish-brown costal margin; the latter is distinctly 
emarginated between the basal lobe and vein 7. — Larva cylindrical, in front (the joints 1 to 3) somewhat 
thickened. Head rounded, hairy. First segment in front on each side with a hair-pencil; second and third 
segments each with a short-haired decorative spot formed of an anterior yellow transverse streak and a poste¬ 
rior blackish one; the second segment above in the median line with two erect hair-pencils; the first black, 
the other one grey. The segments 5 to 10 above each with two black hard coniform appendages; those of 
the eighth segment are longer than the others, and those of the segments 9 and 10 short, knot-shaped; the 
11 tli segment above with a rounded elevation. The lateral appendages are short and long-haired. The skin 
is tan-coloured decorated with red and black streaks or dots. The cocoon is solid, parchment-like, with inter¬ 
mixed short hairs. Natal. 
Ps. concava Strd. (37 c). Forewing and fringes brown with a reddish hue above and beneath. Hindwing concava. 
a little lighter and more scantily scaled, but before vein 7 darker, with a violettish hue; under suiface slightly 
darker than above and without the violettish hue before vein 7; the concave margin appears above and be¬ 
neath lighter than the fringes. Body like the fore wing. Antennae black with light yellowish pectinations. “ 
Separated from the other species by the deeper concavity of the costal margin of the hinclwing and its roun¬ 
ded anal angle, for which reason Strand placed it to a special genus, Alenella. South Cameroon: Alen. 
Ps. tenebra B.-Bak. was described as Glocia, but according to Tams it belongs to Pseudometa. „<$. tencbra. 
Head, thorax, and antennae very dark crimson. Forewing monotonously dark crimson, without any markings. 
Hindwing very dark purple black. Both wings in spite of their dark colours somewhat transparent. Expanse 
of wings: 32 mm.“ Nigeria: Lagos. 
Ps. choba Druce was described as Taragama, but according to Tams it also belongs to Pseudometa. choba. 
Head, antennae, thorax, patagia, abdomen, and legs very dark blackish-brown, almost black. Forewing 
dark reel-brown with two white spots at the costal margin and a white streak at the end of the discal cell. 
Hindwing dark blackish-brown.“ Expanse of wings: 33 mm. Nigeria: Lagos. 
Ps. nigricans Auriv. $. Size and shape of wings almost as in Ps. viola, but the forewing somewhat nigricans 
narrower and the concavity at the costal margin of the hindwing deeper. Head, thorax, and abdomen very 
dark chestnut-brown. Antennae with almost black pectinations. Forewing above very dark red-brown, be¬ 
neath blackish, in the centre more thinly scaled, with a very small whitish dot or streak on the cross-vein, 
beneath at the posterior margin with lighter brownish hair, above there are three indistinct submarginal dots 
or streaks in the areas 5 to 7, exactly as in Ps. basalis Walk. Hindwing blackish, above in the areas 1 a to
