form macula also angled towards the base. Exterior line the same, but only indistinctly double. Submarginal 
line without the light spot at the costal margin. Hindwing white, brownish at the margin. 40 mm. 1 V from 
New Guinea. 
G. costipallens B.-Bak. (38 a) has somewhat narrower wings. Pale brown, lighter at the costal margin, costvpallens. 
greenish in the cell as far as the exterior line. A black streak below the cell as far as the base of vein 2. '\ he 
ring-macida is a black dot, reniform macula pointed outward. Exterior line excurved behind the cell-angles, 
concave between, then on parallel to the margin, vertical at the end. Submarginal line fine, a black streak to 
it from the apex. Hindwing more broadly edged with a diffuse brown. 40 mm. 1 $ from New Guinea. 
G. inexacfa Wkr. (38 a) with its forms has been largely dealt with in Vol. 3, p. 292 and pi. 53 b. In inexada. 
addition to the forms hitherto known we mention yet the form — buruensis E. Prout which is intermediary buruensls. 
between typical inexacfa and the form papuensis JVarr. The hindwing is rather white than whitish ochreous. 
The dark tint of the.centre of the wing is more distinct than in the New Guinea form, but paler than in typical 
inexacfa. The colour of the $ forewing is likewise intermediary between inexacfa and papuensis, the anterior 
half more red-brown than in inexacfa, but less so than in papuensis. The base at the costal margin in the $ is 
more red-brown, not so claret-coloured as in papuensis. According to E. Prout, the statement of the sexes in 
Hamson’s Cat. Lep. Phal. Br. Mus. does not agree with all cases. 
G. guineana Swh. Forewing white, densely dusted with pale chocolate brown. The interior line is re- guineana. 
presented by a large black spot at the costal margin, a smaller one near the apex. Ring-macula and reniform 
macula round, edged with black, with a brownish ochreous central dot, the reniform macula very large. Beside 
the spots mentioned a few more black spots. Black spots at the inner margin near the anal angle, diffuse white 
above them. Hindwing pale grey, with a broad blackish margin. 28—30 mm. New Guinea. 
G. albovenosa E. Prout is said to resemble exacta (37 h) and inexacfa (38 a). Antennae as long tufted albovenosa. 
as in the 1st group. Forewing dark brown, also brownish ochreous or lilac brown, a greenish shadow below the 
costal margin. Marking blackish, indistinct, except the silvery grey apical spot and the adjoining white sub¬ 
marginal line. A white streak at the inner margin, the veins in the marginal area also white. Interior line three¬ 
fold, oblique, undulate. Reniform macula as in inexacfa, but rather rectangular, without a point. Exterior line 
also threefold, similar to that of exacta, but not dentate. Hindwing similar to exacta, but somewhat darker in 
the basal area, for which reason it is less contrasting. 1 <$, 42 mm. New Guinea. 
G. aroa B.-Bak. (38 a) is remarkable for the two large grey spots. Forewing reddish greyish brown, aroa. 
Interior line double, dark brown, notched, extra-angular as far as the submedian fold. A grey spot behind it in 
the cell and behind the lower cell-angle. Reniform macula dark, indistinct, before it traces of lines parallel to 
the interior line. Exterior line double, undulate, downward as far as vein 4, bent to the lower angle of the reni¬ 
form macula. Submarginal line dark, notched, parallel to the distal margin. Hindwing dark brown. $ 46 mm. 
New Guinea. 
G. hades Lower (38 b). Forewing dark red-brown. Interior line rather straightly outward to the sub- hades. 
median fold, then angular. Behind it somewhat lighter, broader light at the inner margin as far as the sub¬ 
marginal line. Exterior line quite indistinct, outward as far as vein 6, then excurved at vein 2, inward at vein 
1 and above it. Submarginal line also traceable. Hindwing ochreous with a dark exterior line which is angled 
below vein 2. The margin behind it is dark. $ 35 mm. Queensland. 
G. cuprescens Pimps. In this species and the following ones the distal margin of the forewing is steeper, cuprescens. 
becoming more oblique only from vein 4. Forewing copper brown, with a slight olive green tinge on it, red- 
brown at the apex. To be separated from the following elongata by the ground-colour. Interior line indiscernible, 
black scales in the centre of the cell, reniform macula large, round, edged and centred with red-brown. Median 
line brown, indistinct, close behind the reniform macula. Exterior line double, somewhat undulate, slightly 
excurved behind the cell, vertical from the submedian fold. Submarginal line finely whitish, with copper brown 
spots inside. Hindwing dark brown. fakfakensis Strd. The interior line of the forewing may also be replaced fakfakensis. 
by black dusting from the costal margin to below the cell, one black spot each at the costal margin behind the 
exterior line and in the submedian fold. $ 36 mm. New Guinea. 
G. elongata Hmps. (38 b). Forewing olive green. Interior line vertical, slightly undulate, black, double, elongata. 
filled with yellowish brown. Reddish yellow scales in the centre of the cell. Reniform macula round, large, 
edged with reddish yellow, a black diffuse spot obliquely above it at the costal margin. Exterior line double, 
widely excurved, notched, vertical at the inner margin. Submarginal line whitish, with reddish yellow spots 
inside. Hindwing dark brown. 9 ^ mm. Assam. 
G. poliochroa Hmps. (38 b) is much smaller than elongata, but similarly marked. Forewing greyish poliochroa. 
white at the inner margin and in the last third of the costal margin, the rest reddish brown. Interior line in¬ 
distinct, double, a white streak before it at the costal margin. A black spot with a light border is in the cell. 
A black streak in the centre of the cell, composed of scales. Reniform macula as in elongata. Exterior line dark 
brown, its course as in elongata. Submarginal line whitish, as in elongata. Hindwing whitish, brownish at the 
margin. — brisbanensis Strd. The reddish brown colour on the forewing is confined to the area behind the interior brisbanensis. 
line at the costal margin. — 9 30—40 mm. Queensland. According to J. Turner, poliochroa is a form of elongata.
