mained unknown, as the species was no more found. One third of the species are African (cf. Vol. 15, pi. 17 i 
and g); the others are Indo-Australian. 
G. niveidisca Hmps. (= triangularis Hmps.) (36 g) and the following niphea exhibit a broad triangular niveidwcu. 
dark spot at the middle of the inner margin of the forewing. Forewing white, feebly pink. A dark brown spot 
at the interior margin. Exterior line double, filled with pale green, from the middle of the costal margin far 
outward as far as vein 3, then inward; blackish behind it as far as behind the centre of the cell, and whitish 
to the inner margin. Hindwing yellowish white. — A from Sumatra shows another less distinct oval spot 
above the spot at the inner margin. Marginal area blackish as far as the anal angle, except a light patch behind 
the cell. — 20 mm. India, Burma, Tonkin, Sumatra. 
G. niphea Hmps. Forewing purely white. The dark interior line undulate, oblique to the spot at the niphea. 
inner margin, dark horizontal streaks before it. Exterior line fine, double, undulate, olive green, outward from 
the costal margin to vein 2, then vertical; blackish behind it as in niveidisca. Submarginal line of black streaks. 
Hindwing brownish white. 20 mm. Ceylon. 
G. pura B.-Bak. (36 g). Silvery white. A reddish brown spot at the base of the forewing. A fine black pur a. 
median line from the centre of the costal margin to the base of vein 3, then sharply inward to vein 1 and more 
distinctly very obliquely outward to the inner margin. Exterior line black, oblique as far as vein 6, then finer, 
notched, bent parallel to the distal margin. Faded reddish brown behind the cell, and a smaller spot at the 
inner margin. The dark submarginal line indistinct, double at the costal margin. Hindwing white. 30 mm. 
New Guinea. 
G. owgarra B.-Bak. (36 h). Forewing also silvery white. Red-brown at the base at the costal margin, owgarra. 
Median band red-brown in front, outside with 2 angles at the cell-margins, then inward, white. Behind it the 
exterior line indicated by a row of black dots. Behind the cell faded red-brown as far as the submarginal line. 
The black submarginal line introangular behind the cell, otherwise indistinct. Hindwing white, margin brown. 
26 mm. New Guinea. 
G. apicalis Hmps. (36 h). This species and the following ones are white, though not silvery white. Fore- apicalis. 
wing somewhat brownish, especially in the marginal area. Two brown radial patches at the costal margin at 
the base. Median line double, indistinct, filled with dark, with a black dot at the lower cell-margin. A fine red- 
brown streak at the cross-vein. Exterior line indistinct, white, outward as far as vein 6, then notched, straight. 
Submarginal line blackish, excurved in the middle, otherwise indistinct, a faded black spot before it at the costal 
margin. Hindwing brownish at the margin. <§ 26 mm. Burma. Only 1 known. 
G. lichenosa Hmps. (36 h). Forewing white at the base. Median line black, undulate, excurved. vertical lichenosa. 
to the middle of the inner margin, pale red-brown behind it. Exterior line dark, double, filled with light, extra- 
angular below the costal margin, then vertical. A white spot at the costal margin before it and behind the sub¬ 
marginal line. This line black, somewhat undulate. Hindwing pale brown. 24 mm. 1 $ from Assam. 
G. niphostola Hmps. (36 h). Forewing white with a very oblique pale brown interior band; a triangular niphoslolc. 
brown median shadow behind it at the costal margin. A black dot at the cross-vein. The double exterior line 
and the submarginal line concave behind the cell, outward above it and below it. Hindwing pale brown. 20 mm. 
1 from New Guinea. 
G. leucopasa Hmps. Forewing greyish Avhite, dusted blackish at the costal margin as far as the middle leacopasa. 
and at the inner margin a little farther. A blackish brown spot at the base. Interior line fine, black, undulate, 
introangular in the cell. Blackish brown scales in the middle of the cell and red-brown scales below them. Median 
line black, undulate, oblique, an indistinct parallel line before it; a black line behind it at the costal margin near 
it, then obliquely to the exterior line at vein 2, somewhat red-brown outside. The indistinct white exterior line 
outside also red-brown. Submarginal line of black spots. Hindwing white. <$ 22 mm. New Guinea. 
G. leucophaea Hmps. (36 h). Forewing brownish white. Interior line oblique, black, undulate, with a leucophaca. 
black dot behind it above vein 1. Median line indistinct, double, oblique, behind it black at the costal margin 
and in the cell-end. Another spot behind the lower cell-angle before the likewise indistinct exterior line. The 
latter is excurved below the costal margin, then red-brown outside. Submarginal line notched, dark. Hind¬ 
wing pale brown. 20 mm. 1 couple from Borneo. 
G. minor Hmps. (36 i) is one of the larger species. Ground-colour olive yellow with white patches. A minor. 
dark brown spot at the costal margin near the base. Median line black, undulate, oblique. Behind it a more 
oblique broad dark band from the costal margin to the exterior line at vein 1. Two black dots at the cross-vein. 
Exterior line black, somewhat undulate, straight, proceeding from a dark spot at the costal margin. Submarginal 
line notched, blackish, white outside. Hindwing brownish white. 28 mm. 1 $ from Ceylon. 
G. obalauae B.-Bak. Forewing pale ash-grey, darker at the base, a narrow dark line forming the border. obalauac. 
Behind it a broad pale area, broadest at the inner margin. Exterior line replaced by a somewhat darker band, 
bordered outside by a white line. Submarginal line dark. Hindwing pale grey. 20 mm. 1 $ from Fidji.
