small, dull brown insect with a very large eye on the tips of the fore wings, and a very small one on the hind pair. The Genus _Heteronympha_ contains seven species, all of which have a wide range along the coast; the Yellow Wood Nymph, _H. merope_, being one of the commonest in all open forest country from Tasmania to Brisbane; it is remarkable from the fact that the sexes differ both in size and markings. The male measures 2½ inches across the wings, which are of a general dull tawny yellow colour mottled with black and brown, the fore pair in a scroll-like pattern, the hind ones only barred along the edges and slightly touched with black. The female, ½ an inch broader, has the greater part of the fore wings black, enclosing two yellow patches fading into tawny yellow toward the basal portion, and with a large yellow angular blotch standing out on the posterior sides; each wing in both sexes has a small eye towards the tip. The dull brown larvae feed upon various grasses, and hide close to the roots. The chrysalis is not attached to the food plant, but rests in a frail network on the ground. _H. mirifica_, found between Sydney and Brisbane, is about the same size as the female of the last species; it also haunts sheltered country. It is of a uniform, blackish brown tint with small eye spots and a broad irregular white stripe across the middle of the fore wings. The Genus _Xenica_ is peculiar to Australia; it contains nine species, four of which are confined to Tasmania, several being found only on the higher portion of the mountain ranges. They are all small, tawny yellow or reddish brown butterflies of small size, spotted and mottled with brown, and have small eyes upon the tips of the wings. _Xenica achanta_, one of the largest, measures about 2 inches across the wings, and is of a uniform dark orange yellow, with the apical portion of the fore wings marbled with dark brown; the hind pair are regularly mottled all over; and the margins of both are edged with two fine black lines; it ranges from S. Australia to Queensland. Several smaller species have been described from the Australian Alps. _X. correae_, described by Olliff from Mt. Kosciusko, feeds upon the native fuschia: _X. fulva_, also described by Olliff, is the male of this species. Family 2. Horned Butterflies. LIBYTHEIDAE. This family contains only a single genus, representatives of which are found scattered over all the warmer parts of the world, but the largest and most brightly coloured forms are found in New Guinea. They are remarkable for the formation of the palpi, which, standing out in front like a beak, are four times the length of the head; the wings are angulated, and the pupa hangs by the tip of the abdomen. One species, _Libythea nicevillei_, ranging from Port Moresby across to Cape York, represents the family in Australia.
