three last abdominal segments above and laterally bright reddish-yellow. Antennae short with short black 
pectinations.“ Size not stated, West Africa. The author states besides that the species is somewhat similar 
to G. bicolor Dew. Whether argibasis is a Gonometa, Pachymeta, or something quite different, cannot be deci¬ 
ded without the type having been examined. 
4. Genus: Hypotrabala Roll. 
Palpi short, last joint tiny. Eyes bare. Forewing: veins 4 and 5 separate, 6 and 7 stalked, 8 from the 
stalk of 6 and 7, 9 and 10 shorter than their stalk, 9 into the costal margin or apex; distal margin almost 
straight, posterior margin bent. Hindwing: vein 3 near the posterior angle of the discal cell, 4 and 5 on a 
short stalk; basal cell large, without accessory veins; vein 7 rises behind the centre of the anterior edge of 
the discal cell. Distal margin of $ somewhat projecting at the veins 2 and 3, between 3 and 6 almost straight, 
in the $ rounded off. • 
Tams unites the genus Pehria Slrd. with this genus. He may be light in doing so, but as the stages 
are still unknown, it may be advisable for the present to keep the genera asunder and to use the name Hypo- 
trabala solely for castanea. Hypotrabala differs from Pehria in the veins 9 and 10 of the forewing being much 
shorter than their stalk, as well as in the different marking. 
H. castanea Holl. $ . (37 e) is easily recognisable from the figure. The $ is much larger (68 mm), with castanea. 
somewhat broader wings, but otherwise coloured and marked like the Cocoon small, oval, dark brown.“ 
Ogowe and Nigeria. Apparently rare. 
5. Genus: Ciirniiiiiiodora gen. nov. 
Palpi short, not projecting beyond the frons; last joint very small. Pectinations of antennae modera¬ 
tely long, slightly shorter in the $. Hind tibiae only with terminal spurs. Hind tarsi with appressed scales. 
Forewing: veins 6 and 7 stalked, 8 from the discal cell, 9 and 10 longer than their stalk, 9 into the distal 
margin. Hindwing: veins 4 and 5 on a very short stalk; basal cell large without accessory veins. 
It was formerly regarded as a Lenodora, but it differs in the longer pectinations of the $, the ab¬ 
sence of the accessory veins in the hindwing, and particularly in vein 9 of the forewing terminating into the 
distal margin. 
G. nigrolineata Auriv. (37 b). G- Ground-colour white or yellowish-white. Forewing above with bright- nigrolinea- 
coloured veins; vein 1, the median, the stalk of 6 and 7, and vein 12 are more or less red (varying from he- ta " 
mochrome to yellowish-red), the others black or on each side finely bordered with black. In the larger $ 
the hindwing is above blackish-grey with light yellow fringes, and both wings beneath are covered with blackish - 
grey. — Larva almost cylindrical, the 2nd and 3rd segments somewhat stouter/ and with feeble deco¬ 
rative spots. Head hairy, bluish-grey with a yellow vertical line. Abdomen beneath yellowish with black cen¬ 
tral spots, on the sides beneath grey with yellow oblique streaks, above with a broad yellow lateral line being- 
interrupted on each segment by a black spot; dorsum with short hair, coloured grey and whitish, and on each 
segment with a black transverse spot which is connected with the black lateral spot. The decorative spots 
have only been produced by the expansion of the dorsal spots and are, like them, clad with short brown 
bristles. First joint on each side with two black, obliquely porrect hair-pencils. Cocoon ellipsoid, parchment- 
like, grey. According to specimens most kindly communicated by A. T. Cooke. 
6. Genus: Auadfasa Auriv. 
Small Gonometinae with broad wings, in which vein 9 of the forewing terminates into the distal mar¬ 
gin. Eyes hairy. Palpi short, not or little projecting beyond the frons. Antennae with moderately long pecti¬ 
nations; the latter are shorter in the $ than in the <$, wings particularly in the $ scantily scaled with short, 
entire-margined fringes, Forewing: veins 6 and 7 stalked, 8 from the apex of the discal cell, or a little united 
with the stalk of 6 and 7; 9 and 10 at least as long as their stalk. Hindwing: veins 4 and 5 stalked, 7 rising- 
very near to the apex of the discal cell; basal cell without accessory veins. 
These small Geometrids only occur in dry steppes or deserts, where the larvae live gregariously on / 
species of Acacia. 
Species with unicoloured not mottled fringes of the forewings, and a pale fawn-coloured or reddish-grey ground- 
colour. 
A. punctifascia Walk. ($ = sobria Walk.) (37 b). A- Head and thorax, red-brown. Forewing above punctifa- 
and still more beneath at the base and costal margin darkened with grey; the two proximal transverse lines scia - 
are thereby indistinct, the submarginal line, however, distinct, composed of bows. Hindwing at the anal angle
