TOO LLOYDS NATURAL HISTORY. 



The type of this genus is G. maia (Klug), which is common 

 in Natal, where the larva feeds on the mimosa. The 

 moth is dark-brown instead of grey. The larva is green, 

 with silvery tufts, and the Kaffirs make snuffboxes of the 

 cocoons. 



A rather larger and paler moth than G. maia is found in 

 Tropical East Africa. The vitreous spot on the fore-wings 

 is much larger, and is set on a diamond-shaped black spot, 

 which rests on one of the dark transverse lines. In the 

 male the wings are subfalcate. It is called G, ivesiwoo^\ 

 Rothschild.

 " The wings measure very nearly six inches in expanse, and 

 are of a very pale colour, especially the anterior pair, which 

 are, however, almost entirely covered with fine black and 

 brown hairs. The centre of these wmgs is ornamented with 

 a small oval mark, half of which, towards the body, is covered 

 with black scales, and the other half is vitreous ; between this 

 and the base is a very curved and irregularly dentate fascia 

 crossing the wing, and immediately behind the eye is a nearly 

 straight, slender, brown bar. This is succeeded by slender, 

 black wavy bars, the space between which and the apex of 

 the wing is divided into, as it were, three compartments, the 

 first of which is covered with small brown patches, the second 

 is paler and covered with very fine black speckles, and the 

 apical part is much darker, with large black specks. The 

 apical margin of the fore-wings is slightly scalloped, the hind- 

 wings are entirely covered on the upper side by a most 

 magnificent eye-like spot, surrounded by successive rings of
